Douluo's transformation from becoming stronger starts with eating soul beast meat

Everyone's attention was focused on the flintlock pistol, and no one noticed the terrifying glint in Su Ling'er's eyes at that moment—a ruthless killing intent.

After seeing the final product, Su Ling'er realized the seriousness of the matter.

Secrecy.

This matter required absolute secrecy; no information could be leaked to the outside world.

Because of this, the thought of killing everyone who knew about it surfaced in her mind.

Fortunately, her rationality quickly suppressed the killing intent.

She strictly controlled all production stages, and, most importantly, the gunpowder was handled by a small number of clansmen, making information leakage almost impossible.

In the entire research institute, only Yuan and his son knew about this matter. As long as they were controlled, secrecy could be maintained.

Moreover, the people who made the gunpowder and the people who made the guns didn't know each other and couldn't communicate, which further reduced the risk of leaks.

Thinking of this, Su Ling'er's killing intent gradually receded, but the solemnity in her heart did not diminish at all. This matter was no longer something she could bear alone.

Quan Yi was currently immersed in test-firing the iron gun and didn't notice his mother's change in expression at all.

After trying several shots, Quan Yi happily put down the gun in his hand.

"As expected of the Yuan blacksmith! Even after so many tests, the gun body didn't shake much, and the barrel didn't overheat. The quality is impeccable," Quan Yi praised Yuan blacksmith.

The quality of this flintlock pistol was top-notch. Whether it was the barrel's temperature resistance or its toughness, it was first-rate.

"Can you take me to your workbench? I'm very curious about how this gun was made," Quan Yi was full of curiosity about everything here, and even more curious about how Yuan blacksmith usually worked.

"Of course, please follow me," Yuan blacksmith led Quan Yi inside.

The interior of the independent research institute was very spacious, not only accommodating a test-firing range but also individual workbenches.

Upon entering the workbench area, the first thing that caught Quan Yi's attention was the large pile of drawings neatly stacked on the workbench.

The drawings were covered with dense drawings, and a familiar expression appeared in Quan Yi's eyes as he looked at them.

Yuan blacksmith introduced, "These are all design drawings for the iron gun. I've organized all the drawings together."

These were all design drawings for the flintlock pistol.

Moreover, some of them were drawn by Quan Yi, and they were drawn very realistically.

Quan Yi was also very surprised by this. In his previous life, his drawing skills were only at the elementary school level, but in this life, he could accurately depict the images in his mind.

Quan Yi felt that this feeling of being able to move his hand at will might be the effect of the Lieyang Gauntlet.

With this skill, Quan Yi could use drawings to explain remotely during communication.

Quan Yi would draw his general ideas into drawings and give them to Yuan blacksmith. After understanding them, Yuan blacksmith would experiment and test their feasibility, and then draw his experimental results and improvement plans into drawings and give them to Quan Yi.

Quan Yi only knew the general idea about firearms, and many of his ideas needed experimental support.

In the past six months, the two of them had used this method to conduct trial and error and modifications, eventually creating this flintlock pistol.

These drawings condensed the wisdom and effort of both of them.

Then, Yuan blacksmith walked to a cabinet on the side, on which were placed various metals and minerals, with the name written under each mineral.

He introduced, "These are all the metals and minerals that the young master entrusted us to collect. This part is mainly the responsibility of my son. He is also working hard to research and test the properties and functions of various metals according to the young master's instructions."

For the sake of ironware research, Quan Yi instructed to collect various metals and minerals.

The materials in this world still need to be researched. Quan Yi's ambition will not stop at flintlock pistols, but if he wants to go further, Quan Yi needs to understand more materials.

And all of this requires years of accumulation and experimentation to accumulate.

"Can I ask about the cost of this gun?" Seeing the mineral material cabinet, Quan Yi suddenly thought of an important question.

"The iron gun that the young master just test-fired, if you don't count the labor, it will cost at least three to four hundred gold soul coins. If you count the labor, this cost will double," Yuan blacksmith explained casually. His tone was as if he wasn't talking about gold soul coins, but copper soul coins.

"What! Why is it so expensive?" Hearing the cost, Quan Yi couldn't calm down. You should know that a Soul Master can only earn ten gold soul coins for winning a match in the Soul Arena.

"Young master, this gun alone consumes dozens of pounds of iron essence in materials. And the price of iron essence on the market is ten gold soul coins per kilogram. The weight of this gun is roughly thirty to forty kilograms.

Iron essence is the essence extracted from ordinary iron ore, and it is extremely tough.

And using this kind of iron essence to manufacture items, the difficulty of use and the difficulty of extraction are basically the same.

So, if you count the labor costs, its cost will double," Yuan blacksmith explained to Quan Yi.

So that's how it is.

Compared to the two, iron essence is obviously more cost-effective.

Quan Yi also understood Yuan blacksmith's thoughts, but his purpose in making flintlock pistols was not for his own use, but for use by family members without soul power.

Yuan blacksmith may not have realized this yet.

The Quan family has thousands of members, and it would cost hundreds of thousands of gold soul coins to equip each person with a refined iron gun.

Moreover, the density of refined iron is too high, and the weight of a refined iron gun is too heavy, which is simply not something that ordinary people without soul power can use.

Carrying thirty to forty kilograms of heavy objects, just walking is a big problem.

"Yuan blacksmith, I admire your attitude of striving for excellence, but I now need at least thousands of flintlock pistols. If we use iron essence, even if our Quan family is rich, it will be difficult to bear," Quan Yi explained to Yuan blacksmith.

Yuan blacksmith's way of thinking is still stuck in the forging thinking of cold weapons, pursuing the durability and toughness of weapons.

However, this concept is not applicable to flintlock pistols. Compared to the toughness of the weapon itself, Quan Yi pays more attention to replicability and low cost.

It was necessary for Quan Yi to remind Yuan blacksmith, after all, he would need to continue to cooperate with Yuan blacksmith in the future.

"I understand the young master's meaning. Using refined iron can indeed greatly reduce costs, and many blacksmiths can easily use refined iron, and labor costs can also be greatly reduced.

Moreover, if we don't consider durability, we can also use wood to replace part of the refined iron, which can not only reduce weight but also further reduce costs."

After being awakened by Quan Yi, a sense of fear suddenly surged in Yuan blacksmith's heart. He thought of the scene of thousands of people holding flintlock pistols and shooting together.

At this moment, he truly realized the horror of this weapon.

At the same time, he also developed a deep sense of awe for Quan Yi.
