Chapter 147: No Turning Back

After hearing what Xu Feng said, Mr. Zhuge was so moved that tears filled his eyes. He bowed to Xu Feng respectfully.

"Master Xu's kindness today will be forever forgotten by us, the Holy Fire Sect."

Start taking action as soon as you say it.

The steel used to produce cannons and pistols is completely different in hardness and some individual parameters.

Xu Feng brought Mr. Zhuge to the branch of the Holy Fire Sect first and improved the steel production process.

Fortunately, Xu Feng had studied these parameters in advance, and he made rapid progress in just two days.

Mr. Zhuge held the newly forged steel and looked at Xu Feng with admiration. "I'm truly in awe of you, sir. You were able to complete such a crucial step in improving the process in just two days, and this steel is clearly..."

In response to Mr. Zhuge's praise, Xu Feng just smiled and waved his hand.

In fact, the barrel is the most important part of a gun. After all, when the bullet is fired, the high temperature and high pressure generated by the burning gunpowder pushes the bullet forward.

When the bullet leaves the muzzle, the bullet head will be launched forward at an initial velocity of several hundred meters per second or even more than 1000 meters per second.

Of course, how far the bullet can be fired depends entirely on this initial velocity.

Therefore, if you want to increase the lethality of a pistol, it is equivalent to increasing the initial velocity in disguise.

But the greater the initial velocity, the higher the requirements for the pistol rifling and barrel.

How to overcome and solve these two major problems is the current top priority.

In order to ensure the smooth progress of the pistol, Xu Feng personally polished the steel according to the pre-designed drawings that night.

Every step here is extremely critical, and he doesn't even dare to let others do it.

"Master Xu, in order to increase the lethality of the pistol, I suggest that we increase the diameter of the muzzle."

Mr. Zhuge looked at the drawings and spoke with insight.

Xu Feng immediately shook his head after hearing this. "Increasing the diameter of the muzzle means increasing the caliber of the bullet, which also increases our production difficulty."

The situation in the court is now extremely unstable, and the right prime minister's faction is eyeing Xu Feng covetously.

If he really wants to preserve the Holy Fire Sect, he must achieve corresponding results within a short period of time.

The most urgent task is to successfully manufacture the pistol, and improving the process can be left for later.

I think about the traditional manufacturing methods used in the past when cannons were produced. In order to speed up the production schedule, the barrels were simply made using the method of sharpening scissors and kitchen knives.

However, when the first batch of cannons were brought to the Japanese pirates' land to fight, their shortcomings gradually became apparent.

In order to prevent similar incidents from happening again, Xu Feng plans to increase the hardness of the steel.

The manufacture of gun barrels requires materials that are strong, pressure-resistant and high-temperature resistant.

Fortunately, Xu Feng had already accumulated experience and foundation in this area when making cannons before, so it is not difficult to use the same method to make gun barrels now.

About an hour later, the newly forged steel was taken out of the high-rise building.

Xu Feng carefully looked at the raw materials and smiled with satisfaction.

However, this type of steel still has some internal flaws and needs to be polished before it can be used to produce pistols.

The surface of steel that has not been deeply processed is extremely rough and black, and looks completely inconspicuous.

However, Xu Feng already had a new plan for this. After the gun barrel was processed, he would place it on a grinding stone and polish it to reveal the glossy color on the surface.

However, in this case, at least two-thirds of the high-quality steel will be wasted. However, this is the only way at the moment. If it is used to directly manufacture the steel, it will explode 100%.

About half a day later, a semi-finished product gradually took shape in Xu Feng's hands.

A semi-finished product is drilled with a hole depth of seven mm, and then after further processing, the diameter of the smooth rifling can reach seven nanometers.

If the distance between the rifling line and the tang line can be squeezed out to reach exactly half the length of a pistol, then the assembly will be a perfect pistol.

But it was not until the last step that Xu Feng discovered a new problem.

The mold originally used to make cannons was too thick and the barrel diameter of a pistol could not be accommodated.

"Mr. Zhuge, we have to polish a new mold."

Xu Feng frowned slightly and scratched his head with some regret.

I was so anxious just now that I even forgot an important step, but fortunately it's still not too late to make amends now.

Mr. Zhuge felt that doing so was too risky.

"Polishing it into a fine mold requires tremendous pressure and gravity. If you fail, it could cause casualties."

Xu Feng certainly understood the danger here, so he planned to complete the next operation independently.

"Mr. Zhuge, please take your craftsmen to have dinner first."

Xu Feng turned around, picked up a hammer, and gently cast and polished the steel.

"No, that's too dangerous."

If it explodes accidentally, it will most likely hurt someone.

"Don't worry, I'll be more careful."

Finally, Xu Feng picked up the hammer and continued to polish. Mr. Zhuge was worried and could only silently guard Xu Feng from the side.

Even if you encounter danger, you can take remedial measures at the first time.

It was not until dawn the next day that the new mold gradually took shape.

At this time, Xu Feng had already collapsed on the ground due to exhaustion. He dragged his exhausted body, leaned on the recliner and gradually fell asleep.

Seeing this, Mr. Zhuge took a quilt and gently covered Xu Feng with it, then took out the polished mold.

He carefully observed the appearance of the mold, and then poured the steel raw materials that had been prepared long ago into the mold.

"Mr. Zhuge, Lord Xu hasn't woken up yet. Why don't we wait until he wakes up before doing it?"

The craftsman standing by was worried.

"Master Xu has worked hard all day, and the next task should be completed by us."

Mr. Zhuge sighed slightly. "If the pistol can truly be manufactured, and the emperor can clear our name, then Lord Xu will be the great benefactor of our entire sect."

"We certainly understand."

"We will certainly remember Mr. Xu's kindness, and we will definitely not refuse if you need us in the future."

Following Mr. Zhuge's order, all the craftsmen gathered in the house.

They first polished the mold according to the standards on the drawing, and then injected the raw steel into the mold.
