Making you a son-in-law is not about making you conquer the world.

The blacksmiths, who had been training for a thousand days, were filled with undisguised excitement when they heard the words "real combat."

For soldiers, combat means going to the battlefield, while for blacksmiths, combat means forging weapons.

They deeply admired Lin Ping's invention of the dog-leg knife and triangular bayonet, and eagerly hoped that Lin Ping could bring even more impressive weapons.

Lin Ping was pleased to see the blacksmiths working so hard.

He placed the blueprints he had prepared in advance in the middle, which immediately sparked the blacksmiths' enthusiasm.

The drawing shows a bolt-action pistol on the left and a series of intricate parts on the right, which are clearly the parts used to assemble the bolt-action pistol.

Since these blacksmiths were all citizens of the city lord, Lin Ping wasn't worried about leaking secrets, which is why he dared to take out all the blueprints for the Shattered Hair Pistol without reservation.

"Such exquisite weapons exist in this world! I've wasted half my life!" an elderly blacksmith exclaimed.

The reason this person was able to achieve great success in iron smelting was because of his open-mindedness and willingness to learn, even in his own area of ​​expertise.

It is precisely because of the superb craftsmanship that the exquisite details of each component can be seen.

“If I’m not mistaken, the essence of these parts lies in the barrel and the spring,” the elderly blacksmith continued.

“That’s right.” Lin Ping nodded in satisfaction. “The core of the Suppressor pistol lies in the spring. Don’t be fooled by its thickness of only a finger; it must be able to withstand a force of over a hundred pounds in order to give the bullet the strongest firing force.”

"A spring as thick as a finger has to withstand a force of over a hundred pounds?" Everyone was dumbfounded, they simply couldn't imagine it.

They truly lived up to their reputation as top-notch blacksmiths; someone immediately raised the question, "If such a fine spring could really be made, it could be placed on a crossbow, not only making the crossbow smaller but also increasing its power."

This is true. As the power source of a crossbow, the strength of the crossbow arm directly affects the power of the bolt. In order to increase the killing power of a crossbow, the crossbow arm is often lengthened, which ultimately makes the crossbow heavy.

However, replacing the crossbow arm with a spring not only reduces the size of the crossbow but also increases its power.

"That's right. As long as the spring is struck against the crossbow, its power can be multiplied, and the crossbow can also be used as a concealed weapon," Lin Ping explained.

"If that's the case, what use is a firearm to us?" the blacksmiths asked again.

Lin Ping was not the kind of person who was arrogant. He humbly accepted opinions. When someone refuted him, he was not angry at all. Instead, he nodded with satisfaction. "The improved crossbow does look very similar to the flintlock pistol, but there are essential differences between them."

Everyone knew that Lin Ping was learned and talented, and that he would not make things up out of thin air, so they all pricked up their ears to listen.

"Whether it's a spring or a crossbow arm, both belong to elastic potential energy. Although their power is not small, it is far less than chemical energy." Lin Ping spoke modern terms confidently and boldly to these students from Huiwen Academy.

"You mean the power unit of the strafing pistol uses chemical energy?" one of them asked.

Lin Ping nodded. "The function of the spring is not only to provide power, but also to provide energy to ignite the gunpowder inside the bullet, thereby producing an explosion and creating terrifying force to propel the bullet out of its casing. If swords are like cold weapons, then the quick-firing pistol is a firearm, a revolutionary change."

As students of Huiwen Academy, they naturally knew what an explosion was and had witnessed its power.

But aren't all explosions devastating? Won't the person involved be harmed?

"Won't the explosion from the bullet hurt yourself? Is the shotgun a weapon that hurts the enemy a thousand but also hurts yourself eight hundred?" someone else asked a professional question.

"So, the barrel needs to be sturdy enough to withstand the power of a bullet explosion. There was once a country that also manufactured flintlock pistols, but the barrels were not sturdy enough, and barrel explosions occurred frequently, so they gave up manufacturing pistols." Lin Ping recalled the Ming Dynasty, the dynasty that once stood at the top of the world.

If the Ming Dynasty had been able to solve the problem of firearms exploding, it might have actually been able to unify the world.

Lin Ping did not have any ambition to unify the world; he was simply acting in self-preservation.

He was glad that these people had all learned modern knowledge and were excellent blacksmiths, otherwise they would have been completely dumbfounded.

"I see. What are we waiting for? Let's get started." The older blacksmith was eager to try, and he picked up a piece of pig iron with tongs and put it over the fire to heat it.

"The spring needs to have strong rigidity, requiring thousands of hammer blows. The barrel needs to be seamlessly cast, preferably from hard cast iron," Lin Ping instructed from the side.

Jiang Yunying followed quietly behind him, somewhat infatuated with Lin Ping's serious expression. Was this still the same husband who was always joking around and only flirting with girls?

This wasn't what surprised Jiang Yunying the most. In order to manufacture the first batch of flintlock pistols as soon as possible, Lin Ping actually stayed here overnight, neglecting to eat or sleep.

Only by eating and sleeping alongside soldiers can one earn their respect and lead an indomitable army.

When Lin Ping was the Grand General of the Wu Kingdom, he didn't work this hard, but as the son-in-law of the city lord, he actually showed the demeanor of a great general.

The logic is simple: no matter how high the position of a general is, he is still just working for the king, while no matter how undignified the status of a prince consort is, he is still a member of the city lord's mansion. This is what it means to start your own business.

Lin Ping only knew the theory; his practical skills were not as good as these blacksmiths'. When everyone was on the right track, he relaxed and even dozed off next to the iron-making furnace.

"My husband, are you trying to move me to death? How am I supposed to punish you for all the mistakes you've made?" Jiang Yunying shook her head, a happy smile on her lips.

The hammering in the armory never stopped all night. When the first blacksmith got tired, the second blacksmith immediately took over. In short, they had to forge a qualified spring in the shortest possible time.

This continued for five days. Lin Ping stayed there for five days as well, while Jiang Yunying would occasionally return to the mansion to check on her parents, not wanting them to worry.

By evening on the fifth day, the iron block, which had been hammered thousands of times, had taken on the shape of a spring and was radiating a bluish-purple light.

"Hurry up, quench it!" Lin Ping said excitedly, knowing that the bluish-purple light meant that the spring had reached its best quality.

The experienced blacksmith naturally wouldn't miss this opportunity. He immediately put the spring into the specially made salt water, and with a hissing sound, a cloud of white mist floated up from the water tank.

The quenching time is extremely short. When the spring resurfaces, it is completely black, giving people a feeling of full of energy.

Although no tests have been conducted yet, Lin Ping has already been able to discern the quality of the springs from their color.

"Success! Finally success! From now on, the Suifa pistol can be mass-produced!" Lin Ping held the trigger spring in both hands and laughed maniacally.
