After a long discussion it was decided that before embarking on the journey into other dimensions or realities, he should know about the wizarding world and learn as much as possible about it first, as it was six months before the grail war, and he was only supposed to travel to train, In the three months before the war he had to learn about the wizarding world and improve his skills.

The trip to the diagonal alley was scheduled for two days later, unfortunately Harry was not allowed to train or isolate himself within an illusory barrier as usual.

During these two days he rested in his room, watched some movies with Jamie and Mark, or studied with Rick, who presented him with several hundred memory orbs containing his knowledge and experiments over the course of a few years.

In addition to a whopping 50 points in intelligence and 100 points in wisdom, he gained a wealth of ideas for new spells and items, along with an extremely valuable and diverse load of knowledge.

On the appointed day, only Zelretch and Pheles accompanied Harry during the visit, as the purpose was to mingle and get the least attention. Harry and Zelretch wore simple black full formal suits, Pheles wore a long black overcoat that went mid-shin under a thin dark blue cloak, his green hair was tucked into a tight bun and hidden underneath a black witch hat.

Since they were already in central London, they only had to walk a few streets and came to an aged pub that seemed to be completely ignored by people passing by.

When they entered, they were in a dimly candlelit environment, the tables were full of dust and crowded with people who were drinking or talking quietly, the bartender was a plump, bald man, cleaning a mug with a dirty cloth.

Zelretch led the way to the back to a brick wall and hit the bricks with his cane and the wall opened.

On the other side a crowd of people roamed around, with occasional owls flying, at first glance it looked a lot like a street fair he'd seen. Wooden stalls on the street selling various strange things like monkey fingers and dragon's liver (which he bought out of curiosity), behind the stalls were several different shops.

The first stop was at a book store where he ordered a copy of every book sold in the store, without the books about a man named Gilderoy Lockhart and books about his alleged adventures, on the advice of his grandfather, who classified both books as disposable garbage.

At first there was some confusion as one of the sellers did not believe he had enough money to pay and refused to pick up the books, fortunately for the seller when Harry was about to burn the store, Pheles pulled out a large bag of clothing and dropped it. on the table spilling several galleons that Harry had left with her earlier.

After counting the money, two salesmen rushed to prepare their order while the manager appeared and began to apologize. After several minutes when all three were fed up with the manager's apology, the clerk arrived and handed over a spellbound bag with all the books inside.

The next two stops were the obscurus bookstore and a second-hand bookstore that he didn't bother to remember the name.

The next store on Zelretch's advice was a trunk store, where he bought two of the largest available in the store, there were 10 compartments, made of manicured and dark leather, according to the old vampire was the most common form used to carry large quantities of objects and occasionally magic beasts and other smuggled objects.

Then they went to a potion shop, and Harry bought all the ingredients along with all the potions available inside, from the most common items like snakeskin to the most exotic like dragon liver and unicorn horns. He repeated the same action in two other stores and in an apothecary.

The next shop they visited was a cauldron shop, where they found a strange variety of this product, tin cauldrons, clay cauldrons, iron cauldrons, decorated, gold, silver, decorated, folding and even moving cauldrons. Alone.

The next stores were an enchanted goods store and a candy store that caught the young man's attention for the strangeness of the names.

Along the way the group passed a huge, completely white building guarded by two ugly little creatures dressed in golden and red robes holding silver spears.

Out of curiosity Harry used Observe, on one of the guards.

Race: Goblin

Name: Kogguff

Age: 32 Level: 18 Next level: 71.46%

Class: Gringotts guard

Hp: 200 Mp: 330

Strength (STR): 7 Vitality (VIT): 15

Wisdom (WIS): 13 Luck (LUK): 11

Points: 0

Looking at the status, Harry realized that although the level is relatively higher than the average person's average, the goblin should not be much stronger than an average ȧduŀt. They, too, were very different from the goblins he fought inside the illusory dungeons, if not for magic, they would not be so much a threat to an ordinary ȧduŀt, let alone a trained one.

Soon afterwards he glances at the shining spear the goblin held.

[Gargott's Goblin Silver Spear - Class: Special]

A goblin silver spear made by goblin Gargott. It is almost indestructible and rejects any mundane dirt, is capable of absorbing anything that makes it stronger.

Effect: Absorb, Paralyzing Poison.

After observing the spear from afar for a moment, Harry lost interest and headed for a nearby alley, called knockturn alley. According to Zelretch here was where all that was dangerous and illegal things are sold and bought, basically an open-air black market.

The first store they came in was called creepy poisons and toxins, despite the idiotic name the store had lots of interesting products, magic acids, poison gas bottles, smoke-blowing candles, and several poison and toxin recipes, that were banned.

Then they went to a bone shop and a necromancer shop, the interesting thing about the latter was that the shop was shaped like a coffin, which was pretty curious.

They visited two different book stores for banned or rare books, of course in the end the price was quite high compared to other stores they had already visited.

While visiting store by store, they soon found themselves in front of a store called Borgin and Burkes.

The shop was a strange oddity, you could find almost everything inside, from dragon leather clothes to rare poisons and cursed necklaces. The salesman and owner, Mr. Burke, was a rather cowardly man, trembling with fear just looking at Zelretch's red eyes.

In addition to a coward he was a master of dark articles and a good salesman.

First, he presented the items from his showcases and bookshelves, then he showed some of the most interesting items and finally when he saw that they still had plenty of money after several purchases he started showing the most valuable items.

In all, they left the store with over 20,000 galleons of purchased products, much to the delight of the man who already treated them as friends he had not seen in a while.

Finally, the last store was a very illegal pet store called menagerie oscurus, the owner was a very beautiful woman with long brown hair and almond-shaped eyes, but deep down she could see a hidden cruelty that showed when she kicked a house elf With joy shining in the eyes.

The place was full of big and small cages full of different creatures Harry had never seen. After exchanging a few pleasant words with the owner of the place, the young man began to walk around the store, watching the creatures and the prices.

After walking around the store and checking each cage or cage along with the prices, Harry talked quietly with Zelretech and Pheles, and pulled out a huge pile of money making her eyes widen and her chin slacken.

About an hour later and over 50,000 lighter galleons, Zelretch teleported them back.

Harry was curious about the method the old vampire had used, as it was so different from the teleportation spells he knew, unfortunately all he received were vague answers and an annoying smile from the old vampire, who seemed to relish his frustration at each answer.

Stopping to analyze the situation, Pheles also seemed to be enjoying it.

Before going to his room, he asked the old vampire why the wizards were not part of the abyss. The answer was quite long, most of wizard-kind didn't know about the abyss nor they were bounded by its rules.

So a wizard or a witch could easily show or use magic in front of normal people without consequences, the only reason that they didn't do it was because or wizard-kind laws, however it don't stopped some people.

The abyss didn't act much in the wizard world mostly because two factors, first wizard were considered by Gaia as normal people so the members of abyss were restricted in their actions, the second reasons was a treaty made by some wizard and some forces in the abyss.

The only people that could act directly in the wizard world, were called War-wizards. A War-wizards that by any reason became part of the abyss, each of them was a lot powerful than a common wizard.

An ordinary wizard were a rank G or F and a hit-wizard who was the equivalent to a soldier was an E or D rank, some of the most powerful like Grindelwald or Dumbledore were C in their bests, a War-wizards were ranks C or B, with some rare members being a rank-A.

The number of War-wizards was scarce, having one was already considered rare. As members of the abyss most of War-wizards were infamous, being know by their "dark" magic, power and hearthless experiences. War-wizards were feared by their power and for being uncontrolled among others wizards.

9 in 10 War-wizards were known by a large massacre, usually the victims were poor idiots or law enforcements and politicians, making all the wizards' governments, fear them, since they were too powerful to be controlled or restricted by law or politics.

The most powerful War-wizards, were Ranks A and they were Franklin Beans in the USA, Mukhina Vitalievna in Russia, Huangfu Haoyue in china and Ranjan Adhya in India.

The UK also had one War-wizard Ruth MacPhilip, a Scottish B-rank woman known by massacring a large group of death eaters, werewolves and aurors, while she also fought both Dumbledore and Voldemort together.

In the wizard world they were feared and avoided, but in the abyss even Huangfu Haoyue the actual most powerful War-wizard, were nothing special, any second and some third-rate groups could kill him, not even to mention the first-rate groups or S ranks.

The next three weeks were intense in Harry's life, it took about two weeks for Harry to learn most of the books he bought in the wizarding world, with his high status in intelligence and wisdom, he was able to learn everything easily and after he distributed the points he was saving, it became even easier.

There were huge differences between the wizarding world magic and the abyss, they were present in both spells and creatures that existed.

By using his ability to learn spells in a book, he would gain a skill of the same name, however when he tried to learn spells from a wizard book, he gained the skills, Spells, Enchantments, and Transfiguration.

Spells learned through wizarding books would appear directly in one of these three categories. It was a little weird, but it had its advantages, he didn't have to practice spell-casting until he mastered it perfectly, he just had to use spells of one of these three categories and the level would rise.

There were also others branches but them were purely theorical like, herbology and Arithmancy.

In the end the wizarding magic was far more versatile, but it lacked the power that the common spells of the abyss had. If a strong wizard and a common spellcaster of the abyss used the same spell, in most cases the used by the spellcaster would be stronger.

In addition to the spells the creatures were also very different, a wizard Ghoul, were 120 cm ogroid supposedly related to trolls, Ghouls in the abyss were undead creatures, the size of a human. As long as he had only heard, the werewolf wizards did not control their actions and were no more than beasts, while werewolves of the abyss could turn at will and keep control.

Goblins in the wizarding world were totally different from the wild green-skinned goblins that would appear within illusory barriers.

A vampire of the wizarding world was only slightly physically stronger than a human, and lost the magic used by wizards for a weak magic used by vampires, in the abyss, vampires were very strong, had a wide range of abilities and spells, and could use the same spells as everyone.

In addition to wizarding world magic, Harry began to learn about summoning magic and contract magic from his algebra teacher who was one of the clan's key sorcerers.

A week later, in the streets of London an intense battle was taking place all over the place, thousands of different monsters infested the streets in a huge chaotic battle, giant mices, bus-sized tigers, green goblins, gardens gnomes with sickles, zombies, ogres, trees with teeth and eyes, even giant cars, statues, and cell phones fought, and a multitude of creatures of all shapes and sizes fought each other and devoured the fallen.

"Dude, things are crazy down there." Tigg commented watching the fight going on below.

At the top of a building, Mark, Jamie, Angela, and Harry, along with two other people, agreed with the man's words, watching the huge unbridled struggle down the streets, it was an extremely worrying situation for a number of reasons.

"Get ready, we'll get down and we have to clear this area as soon as possible."

Harry said after he analyzed the situation below.

The vast majority of these beings were called minions, remnants of negative thoughts and emotions that gathered within illusory barriers given life to these beings, these "remnants" attacking and absorbing each other to evolve.

Above the minions were the demons, they also had all sorts of different shapes and powers, the newly generated were not so clever, but if given time they would gather knowledge and become more cunning than humans.

They would organize attacks, form groups, as well as all kinds of hostile behaviors.

In recent weeks, an economic crisis has come as a surprise, catching many people off guard, this economic crisis has culminated in the bursting of the English property bubble, leaving millions of people in a state of despair.

High unemployment, falling real estate prices and the failure of multiple businesses led to a huge wave of suicides and negative emotions, which flowed into illusory barriers causing a massive increase in the already high number of minions and demons appearing.

Given the city's current population, the numbers of minions and demons were already quite high, and that rate increased so much that even the large clans around the city were having trouble controlling the situation.

That's why Tigg, Mark, Jamie, Angela and Harry, who weren't part of the red oak clan, had to help control the situation.

The two newcomers were Stacy Morgan and Charlie Rhodes, Harry bought them both for the abyss auction, both were part of abyss groups that were destroyed by stronger groups and eventually sold out.

Stacy was an aura user, not very strong, but still pretty decent for her level, Charlie was a magic user, a decent wizard, but not very skilled at fighting.

Neither was a good or decent person before, but the contract magic and the ring of ownership kept them obedient.

"Tigg, you're in charge, I'll leave these two with you."

Harry warned and jumped off the building.

As he fell, Harry opened the inventory and pulled out a sword. It was a shiny and beautiful sword, the blade was long and thin, only two fingers thick and 170 cm high, made of pure silver, the hand guard was 'C' shaped with a small purple octagonal jewel, the handle was Simple big enough for two hands, the Snitch was small and simple fish-tail shaped.

[Harry Potter's Goblin Silver Sword - Class: Special]

Weeks ago, when he observed a goblin guard's silver spear, his Structural Grasp understanding completely analyzed the spear, creating a design model for the weapon, thereby copying the method and spells used by the goblins, and using it to make his own weapon. Relying on his own abilities, he added various spells of his own to the blade.

Turning his body in the air, the young man posed perfectly above the head of a huge red dog and buried the sword in his skull without difficulty, he leapt the dead dog's head toward a being shaped like a huge cell phone.

With a flick of the sword he cut the cell phone in half and raised his free hand capturing a club held by a pig man in a suit, the sword cut the air and split the pig man in half from top to bottom.

Kicking the ground, Harry crossed several feet and reappeared in front of a huge spider and buried his sword between her eyes. At the same time his instincts kicked and he swung his sword quickly deflecting two sharp green thorns.

The attacker a cactus with various eyes and mouths, which began to shoot thorns, using the old Feng clan's sword technique, he easily deflected the thorns and cut the cactus into several pieces.

Shortly afterwards a purple lightning bolt and several metal spikes hit him, the blast caused by the lightning to raise a cloud of dust on the spot. The dust slowly lowered, revealing Harry completely intact surrounded by a silvery gaseous aura.

Silver Body, an advanced body strengthening technique evolved from the skill, Steel Body, which in turn was an evolution of the Steel Skin skill. A powerful skill that enhanced the body and could easily block some attacks.

Glancing at the attackers, Harry saw a woman wearing dress with huge buŧŧerfly wings, and a man wearing a white shirt and jeans with completely black eyes.

High Pixie - Demon - Lv 60

Iron Eater - Demon - Lv 63

Using teleportation magic, Harry appeared on top of the fairy woman and landed a kick on her back sending her to the ground that cracked on impact, then he disappeared and reappeared in front of the iron eater and grabbed his head and smashed against the floor, making both demons unconscious.

With both demons unconscious, Harry opened the inventory and pulled out a staff. The staff was long bident (trident-like but only two), the U-shaped tip was sharp made of bone-white metal with a small skull in the middle on each side, the handle was made of black metal with details of Bones in bronze.

Hades Staff (Replica) Rarity: Mythic / Class: Staff

A replica of the staff is said to have been used by Hades, an ancient Greek god. It has two sharp points that can be used in combat, a symbol of Hades, the god of the underworld, who rules darkness and the dead.

It has less power than the original staff, but it is powerful nonetheless.

Effect: + 500% magic attack power

Effect: 200 MP Per Second Recovery

Effect: Permanently Applied 'Negative Energy' Skill

Effect: Nirvana Ability Available

Effect: Create Undead skill available

Effect: 'Undead Control' ability available

The staff had been one of the many things he bought with the Zelretch voucher on his birthday, thanks to the voucher he could buy items that like this staff could not be bought with cash alone. In fact, he had bought so many things from the voucher that the old vampire almost had a heart attack when he paid off the huge debt of a few billion.

He should probably study if vampires could also die from a heart attacks for futures purposes.

Harry conjured chains made of purple mana, and used powerful sleep magic, causing both of them to fall into a even deep sleep. Shortly afterwards the young man pointed his staff and cast a new spell.

"Eternal Theft Skill."

The spell struck the iron-eating demon and a dark aura came out of it forming three black spheres that Harry picked up, and used his ability to observe.

Iron Control Essence

Unique Legendary item.

An orb that condenses the essence of iron control possessed by the iron-eating demon. When consumed grants you the ability to 'Control Iron'. When consumed by someone who has the ability to control iron increases the skill level and increases their skills.

The other two were the essence of iron generation, and the essence of magic, while consuming the essence of magic, increased intelligence status directly by 20, it was like climbing four levels at once.

Then by consuming the iron control essences and essence of iron generation, he gained the Ferrikinesis ability. Which allowed him to generate, shape and control iron at his will, unfortunately the ability only allowed to control and generate iron and no other types of metals such as copper or lead.

As soon as he had absorbed the iron-eater's abilities, he cut off the demon's head and put the body in inventory, a demon's body was much valious to be wasted, when he was about to do the same to the fairy an idea suddenly came up, making in change his plans.

"Total Forced Servitude Contract"

As soon as the contract was formed, Harry felt total control over the unconscious demon, the forced bondage contract magic created a link between the user and the target, through this link the user gained full control over the target.

Of course, there were some limitations as suicide orders would not work.

With the contract formed, he removed a small orange-sized cube from the inventory and pointed to the fairy, a vortex emerging from the cube and suċkɨnġ the unconscious fairy inside. Harry strapped the cube to his waist and flew somewhere else.

Deciding to test his new skill, the boy put his sword away, summoned dozens of iron weapons and fired them toward a group of fighting demons, most of the weaker dying quickly, while the stronger survived only sustaining minor injuries or no damage at all.

Harry raised his arms and created a vortex of iron dust that began to grow in size, several of the demons and minions saw it and tried to attack, but all attacks were stopped by the energy barrier formed by the silver body.

As soon as the vortex reached its maximum size, it lowered its arms toward the multitude of minions and demons, burying them beneath a huge amount of iron dust.

"Powerful wrath Lighting."

Harry said streams of powerful lightnings bolted from the tip of the staff striking the iron dust on the floor, making it glow blue with the powerful electric energy. The lightning lasted only a few seconds, but it was enough to melt some parts of the iron on the floor.

As soon as it was over, he saw Tigg covered with yellow rays, shooting down powerful bolts from above as the rest of the group struggled with what looked like a building size huge green tiger-striped octopus covered in burning mucus

It definitely was going to be a very long day.
