As soon as he returned to the inheritance palace, he looked for AI and asked, "Can you open the last building? I need to finish this as soon as possible."
"Yes." AI nodded and waved his hand toward the last building, the sphere building.
Alex took a peek and saw a few big translucent crystals sealing a certain book. He thought. 'I wonder which book I need to choose. The suitable one, of course.'
"Please enter the building."
Alex turned around and entered the building. He found five books inside and read their titles one by one. "Inverted Dimension, Space Compression, Space Distortion, Black Hole, and Subjective Reality."
"Damn. They sound powerful… Every single of them. I think I have learned Space Compression back then, but I have never had the time to properly use it. Maybe this one is different and it will be suitable for me?" Alex muttered as he looked at them with a curious face.
Suddenly, the tower's door was closed, leaving Alex alone with the five books. He was contemplating which book he would choose for this test. "Let me see. I don't know what the usage of this Inverted Dimension is, but I guess it's something like a space that turns everything upside down.
"Space Compression… The one I learned compressed air and such to create a blast that releases a powerful shock wave. However, my Pure Fire is far more powerful than it, so I have never used it. I wonder if this one is the same…
"As for the Space Distortion, I am not very sure. The effect must be distorting space, but I can't imagine the end product. On the contrary, Black Hole must be implying the real black hole… Just a smaller one.
"Last but not least, Subjective Reality. This is something that I can't understand." Alex tilted his head in confusion, wondering which one he needed to choose.
However, his thought was shattered by a paper that was left behind by the Dungeon God. It was the instruction for the last test, so he picked up gently, knowing that it must be saying he needed to choose one of them.
Whether it was fortunate or unfortunate, Alex froze when he read it.
"For the one who managed to complete the first four tests, I applaud you for coming here. Just like before, you wouldn't be able to escape from this place unless you have mastered everything. This is a kind of reward from myself, so be sure to take the books, alright?
"My instruction for this test is simple. Because I don't like hearing 'You need to choose one of these treasures in every single inheritance I had met in the past, I decided to not follow their thing. Instead, just take it all! Hahahahahaha!
"This is the real instruction. You need to master all these five books inside this tower and the door will only open when you have cleared it. At the same time, you can enter the Greatest Vault of all time, my fault. Now, go! Take them all. Hahahahaha!"
"…" Alex's eyebrows twitched as he wanted to throw this paper to the floor.
"Seriously? I mean, this is surely a fortune since I can learn all of these at once, but I also need to worry about the timing. Luckily, the previous tests didn't take too long, but one and a half years for all five techniques, huh." Alex facepalmed and shook his head helplessly. "I wonder if this is luck or misfortune. Anyhow, I need to finish this as soon as possible."
Alex activated his Spirit Eyes and found that the crystals were made of Space Energy, so he quickly covered his hand with it and entered the first crystal.
Surprisingly, it slipped in that solid crystal as if his hand was swimming inside a liquid. He grabbed the book and pulled it out.
"The first is Inverted Dimension," Alex muttered and opened this red-colored book.
"Inverted Dimension is a special dimension that reverses every single law in the world. The Gravity will pull you to the side or even to the top, so your sense of direction will become weird after this.
"Everything will be according to your will, allowing you to even set an amount of energy in this space. For example, if you are an Alchemist, you can filter what elements you want in this certain space or something like that.
"It's a technique that is useful for combat and miscellaneous things, so use it only when you need it."
Alex contemplated for a while before looking at the other four books. "That's right. I can choose which one do I want to master first, right? I need to read all of them first and determine which one of them is easier."
With that thought in mind, Alex walked to the second crystal and took the book.
"Now, this is the Space Compression book." Alex smiled and started reading.
It turned out the Space Compression Technique in his hand was far superior to the one he practiced. The Space Compression allowed him to seal someone's attack and compressed it.
"Hmm, I can store up to ten beads that contain powerful attacks. This can become a small bomb for me. Unfortunately, I can't give it to the others since if I want it to explode, I need to resolve the technique." Alex narrowed his eyes.
"Still, if I store my own Pure Fire, Lin Xingzhi's attack, and the others' strength, this will become an ultimate trump card." Alex smirked before slipping the second book to his other hand that carried the first book.
He then walked toward the third book and grabbed it without difficulty. "The third book is Space Distortion Technique.
"This technique has a similar effect to the covering. It allows me to distort someone's attack to a certain degree. If someone is stronger than me, this technique will give me a big opportunity against them. Of course, its strength is far stronger than covering.
"Instead of creating a barrier, I should use this technique to deflect my opponent's attack." Alex then turned around and reached the fourth book. "Next is Black Hole. The name alone has told me everything.
"It's basically creating an artificial black hole. Like Lin Xingzhi who managed to create all elements disturbances, I can create a torrential wave of Space Element to create a powerful shucking force. I will then become invincible. That is if I don't meet someone stronger." Alex sighed.
"Four books are interesting for me, so I will check the last book first. The one that piques my interest the most, Subjective Reality."
The moment he took the book, he decided to sit down and read what this technique was all about.
"Subjective Reality is the world's entirety. It's impossible to distinguish between a dream and reality. It's a technique that allows the user to manipulate the boundary between fantasy and reality. And this is the ultimate technique I have ever created…" Alex read the first few sentences out loud and gasped. "This… This is the original technique that the Dungeon God created?
"If I am not wrong, the Dungeon God is just a pseudo title. His real title is Space God." Alex was sweating because this might be at the same level as Phitrus's Fire Authority. "Anyway, the user can control the boundary between fantasy and reality… What is and what isn't, turning one into other and blurring the border between them.
"With enough compression, you can create an attack that is close to the perfect one. If one needs to be wary of one thing, it's the only flaw of this technique. No matter what kind of level you've achieved, an illusion is just an illusion. It won't ever interfere with reality.
"But if you are serious in learning this, you need to increase your repertoire, forcing your opponent to think which one is actually your real attack. This technique also carries the traces of pain and sense of touch, so the enemies will find it hard to distinguish which one is the reality.
"Hmm. I can probably see this through with my Spirit Eyes, but my eyes are the only ones that can see through Spiritual Energy in everything. Anyhow, I think I have chosen the order of these five books.
"First, I am going to learn the Space Distortion since I have understood the basics before moving to the Black Hole for the same reason. The third will be Space Compression since it's the only one that is not related to a dimension type technique.
"Then, I will choose the Inverted Dimension since it's easier than the Subjective Reality. And with this, I'm set." Alex nodded with a serious expression as he began reading the first book.
It wasn't that thick, so Alex finished it within three hours. Unfortunately, when he created a Simulation Room, it seemed to cause a certain reaction inside the tower, preventing it from activating.
Hence, Alex decided to rely on his Spiritual Energy and Void Flower instead.
As the name implied, the Space Distortion deflected something that passed through it. During the first week of training, Alex was able to achieve the smaller success where he could erect the barrier, albeit it was still unstable.
It took him another two weeks to create a solid one before testing it himself.
He summoned the distortion barrier and hit it with his own Pure Fire. Unfortunately, the challenge was a failure because Alex's Pure Fire ended up burning it as if reacting to it.
Alex could only sigh since he controlled the Pure Fire to do no harm earlier, but this accident told him that everything wouldn't go according to his way.
Still, that experiment actually gave him good data about his Pure Sword Qi. Because the Pure Sword Qi and Pure Spear Qi had a similar characteristic to that of Godly Pure Fire, he managed to break that Space Barrier with his weapons.
For now, the only thing that had no power to break it was his array. Sadly, his array's main purpose was to control the battlefield due to how fast he could create an array.
When the Spear from the array hit the Distorted Space, it passed through the barrier without a problem but ended up going in another direction instead of him.
Although it looked like something he shouldn't use in a battle, it was a good technique for one on one battle since he wouldn't accidentally injure someone from his side.
Ultimately, it took a total of one and a half months to master this technique.
The same applied to the second technique, Black Hole. Alex already had the foundation, which was the spiral wave of Space Element.
According to the book, he needed to learn a bit about the gravity and torque of that technique before he could master this technique.
Nonetheless, it was already good enough for him as Alex spent a total of three months learning the first two techniques.
The Black Hole was quite special than what he had found this whole time. Because of the smaller size, the sucking force was stronger, so it would be absorbed faster. Yet, Alex was a bit sad since he could literally slash his own Black Hole or even burn it.
No matter how you beautified the technique, it was just a technique. The Black Hole couldn't be compared to that of the natural one that could suck planets.
Either way, Alex was satisfied with the two techniques as it would improve his fighting style a lot. In fact, he might be able to kill a Rank 3 God after learning everything in this place. And yes, it was with his Rank 5 God cultivation stage.
Now that he almost reached Rank 4, Alex should be able to do more like challenging a peak Rank 3 God. Unfortunately, Rank 2 God was still too strong for him, let alone the God King that was said to have a gap with the level before it far surpassed what people had experienced so far during the previous stages.
After mastering the two techniques, Alex finally started learning about the third one, Space Compression.
