There was a lot more work involved in crafting an Upper Lv 4 weapon, compared to a Lower Lv 4 weapon. More than 20 materials were required to craft just one weapon.
He put more than a dozen main materials into the furnace and steadily started to melt them. Now that Su Mo had advanced to the True Darkness Realm, the fire created from his Dark Force was even stronger. It wasn't long before everything had melted.
It took less than 15 minutes for all the materials to melt.
The next step was to remove the impurities from the melted materials. Thanks to his strong willpower, he easily sifted them out.
He spent another 15 minutes refining the melted materials to their purest form.
He added three more materials into the furnace.
Two of them were added to increase the weapon's durability, while the third was added to stabilize it.
Ou Lianzi's craftsmanship Legacy had meticulously detailed the craftsmanship techniques for various weapons. It included the required amount of each material, when to put each material into the furnace, and the function of each material in the craftsmanship process.
All Su Mo needed to do was follow the instructions in the Legacy.
It didn't take long before all three materials had melted and blended well with the solution. Su Mo stopped fueling the fire.
He used his strong willpower to control the casting of the weapon.
The ball of liquid slowly stretched to form an 80-centimeter long saber.
"I overdid it!"
Su Mo frowned. The knife should have been a meter long, given the materials' quantity.
He hadn't controlled the duration and degree of the fire well enough, resulting in the materials being over-refined.
This was due to his lack of experience. After all, he had only spent a few days in total practicing craftsmanship.
When the long saber was formed, he opened the lid and waited for the saber embryo to cool.
Once the saber embryo had cooled, he poured the quenching liquid into the furnace.
A moment later, a saber with imperfections appeared in the furnace.
There was still more work to do. He fueled the furnace again with Dark Force to forge, heat-treat and finally, sharpen the saber.
Another two hours passed before an Upper Lv 4 long saber was finally crafted.
He nodded with satisfaction as he studied the saber in his hand. The saber had turned out a bit on the small side, but it was of good quality.
This was due to his strong willpower!
"That wasn't too difficult!"
Smiling, he recalled what Ou Lianzi had said. "You've got an innate willpower talent that is unprecedented. It's as if you were born for craftsmanship."
He didn't think Ou Lianzi was exaggerating; he took extremely easy to craftsmanship.
Guided by Ou Lanzi's Legacy, his craftsmanship path would be mostly smooth-sailing, free of major obstacles.
Su Mo spent the rest of his time in the Divine Map's Space crafting Upper Lv 4 weapons.
He successfully crafted all kinds of weapons, including long swords, long sabers, battleaxes, a shield, and spears.
The more weapons he crafted, the more adept he became, and the better the quality of the weapons.
After ten days, Su Mo had used up all his craftsmanship materials and crafted a total of 310 weapons.
He had only failed once. He had been a little too impatient in adding the quenching liquid, which led to a sword breaking apart
Crafting more than 300 weapons in ten days significantly boosted his level of experience.
"I should be ready to try crafting Lv 5 weapons next!" He beamed.
He packed all the weapons into his storage ring.
It was time to sell the weapons and some of the treasures in Nie Yu's storage ring for Spiritual Stones to temporarily alleviate his poverty.
Su Mo willed himself out of the Divine Map's Space and appeared in the thorn bushes.
He put the Divine Map away and took off.
After more than two hours' flying, he spotted a city before him.
The city might have been smaller than Dalong City, but it was big enough for the Sky-sea Pavilion to set up a branch.
He landed and entered the city.
He asked around and learned that the Sky-sea Pavilion indeed had a branch here.
The branch Deacon immediately recognized Su Mo the moment he entered the branch.
Su Mo was just too famous right now. He was a top talent who had managed to make the List of Top 1,000 Talents at the Enlightenment Realm. His achievement had amazed everyone and many had seen his portrait.
Moreover, since Great World City was not too far from here, Su Mo was even more famous around these parts.
The Deacon quickly introduced him to the elder of the branch.
Su Mo sat on a sandalwood chair in the living room. A clean-shaven middle-aged man sat in the master's seat.
The man was dressed in blue. He had a look of command and his eyes were sharp.
"What an honor to have you here! Sorry for the late welcome!" The man greeted Su Mo politely with a fist salute.
"It's my honor as well!"
Su Mo returned the greeting. He could tell that this man was a Martial King Realm expert and paid his due respects.
Su Mo did not treat it as a sincere apology, he knew that they were just polite remarks.
"There's no need to be humble. You're a young man blessed with unprecedented talent. You have more potential than all the other geniuses of the Central Continent!" Elder Wang exclaimed, his eyes full of wonder.
Normally, he would not have brought out these formalities unless the visitor was one of the top 100 talents on the list.
Yet, Su Mo was different. A man with such incredible talent was bound to achieve greatness in the future, so he was especially polite in his mannerisms.
"You're flattering me." Su Mo laughed.
The man shook his head and asked with a smile, "How may I help you today?"
"I wish to sell some weapons." Su Mo got straight to the point.
"Oh? What level are these weapons?" Elder Wang asked.
With a wave of his hand, over 300 weapons appeared in the living room.
Elder Wang reached out to summon a long sword.
"Upper Lv 4!"
He studied the sword and nodded.
He rose to his feet and carefully checked through all the weapons, his eyes flashing with excitement.
After a moment, the man said, "Su Mo, these weapons are all Upper Lv 4 and do not vary much in terms of quality. I propose a unit price of 80 Upper Spiritual Stones for each weapon. What do you think?"
"80 Upper Spiritual Stones per weapon?"
Su Mo did a quick calculation. If he sold each weapon for 80 Upper Spiritual Stones, 310 weapons would equate to 24,000 Upper Spiritual Stones.
