Now, the family allows Chu Jiao to drive by herself, allows her to recruit bodyguards she is satisfied with, allows her to go home a little later, and so on.

After making a phone call home and making up an excuse to go back a little later, Chu Jiao and Zhao Youcai moved all the application items into the lathe room.

The two pistols used in the raid were both revolvers, one was a 0.38-inch Colt pistol and the other was a 0.32-inch Weber Les Coult pistol.

Chu Jiao is not very satisfied with this, but something is better than nothing, and now is not the time to pick and choose.

From seeing and learning, to hands-on operation, Chu Jiao was most interested in lathes in addition to planning and rebuilding in the car repair shop.

The workers thought that the eldest lady was purely curious, and no one knew what Chu Jiao was doing for this, let alone what the use of some small parts she made from time to time.

Zhao Youcai was the same, watching Chu Jiao bring a big box, and took out iron pipes, gaskets, rubber, and some small parts that he couldn't tell, he was also confused.

Chu Jiao carefully measured the caliber of the gun, then replaced the rotor head, drilled holes in several small parts, sharpened the front sight of the pistol, and put the threads on it......

This girl, who looks like her sister when she does things, looks like her sister.

Zhao Youcai didn't know why, looking at Chu Jiao's busy work, he seemed to see his sister again, slightly curled the corners of his mouth, and showed a faint smile.

Most of the parts are machined, but it takes a little effort to drill the hole. Chu Jiao had to thank Shen Chen for the drawings and the few words of guidance on the phone.

Now, with her own hands, a knock-off version of the silencer is gradually taking shape and finally being assembled.

Call! Chu Jiao let out a sigh of relief, fiddled with the toys in her hands, and smiled.

Although it does not reach the level of fine processing, it is not satisfactory.

In order to ensure the effect, Chu Jiao listened to Shen Chen's suggestion, and also installed a thick rubber with small holes in front of the muffler.

The gadget is replaceable, and the holes slightly smaller than the caliber of the bullet also enhance the sound duffling.

"Look, screw this to the muzzle." Chu Jiao proudly raised her eyebrows at Zhao Youcai, put the silencer on the pistol, and looked around, the doors and windows were closed, and there was no one in the factory, so you should be able to try it, right?

"Phew!" Chu Jiao shot at the corner of the wall, and the sound sounded like a firecracker, but the effect was not too satisfactory.

Zhao Youcai's mouth opened wide, he didn't expect Chu Jiao to be a stupid and bold person, and he dared to test the gun here, let alone that the gunfire was not as deafening as he imagined.

The main sources of gunfire are the violent vibration of the explosive gas of gunpowder when it is ejected from the muzzle, and the popping sound produced by compressing the muzzle air. As for the sound of the primer, it is not very loud, it is similar to a cannon.

At the same time, because of the air leakage between the nest of the runner and the barrel, the silencer is less effective than an automatic pistol with good breath-holding performance.

Of course, even with a perfect silencer, it's not completely silent, it's about reducing noise and changing the timbre to improve concealment.

"This, you figured this thing up?" Zhao Youcai was surprised and admired.

Chu Jiao raised the gun again and tried it, the front was relatively heavy, and it required a lot of wrist strength, if it was holding the gun with two hands, it would be more stable.

"Listening to my brother, there are people in the United States who make gadgets for poaching, and I want to imitate them." Chu Jiao handed the gun to Zhao Youcai and said with a smile: "This way it will be much more convenient to assassinate." If it were a different pistol, it might work better. ”

Zhao Youcai took the gun, raised it and put it down, feeling the difference in feel.

Chu Jiao started the lathe again, made a silencer for the other gun, and said in her mouth: "Try two shots, I don't think you can hear it outside." ”

Zhao Youcai raised the gun, hesitated for a moment, then put it away and walked to Chu Jiao's side, and said, "I'll do it, you will guide by the side." ”

This silencer took a little longer, Chu Jiao explained while teaching, Zhao Youcai didn't understand it very well, but the shape of various parts, as well as how to manufacture and install, should have learned how to draw a scoop according to the gourd.

"This gun could be quieter." Chu Jiao judged according to the caliber of the pistol, held the gun in both hands, and fired a shot at the foot of the wall.

Oh, like opening the cork of a champagne bottle, maybe even bigger. However, it is indeed quieter than just now.

"It's really small." Zhao Youcai was also interested, took the gun, first with one hand, then with both hands, and fired a shot steadily.

Looking at the bullet point, Zhao Youcai thought about it, nodded and said: "Although the muzzle of the gun is a little heavy, it can also be adapted, but it doesn't make the muzzle jump too much." ”

Muzzle jump? Chu Jiao was thoughtful, guessed and said: "If you want to say that the muzzle jumps up, it seems that I also feel this way when I shoot at the shooting range." When we have another gun, let's try again. ”

"Take your time, with these two guns, you can do a lot of things." Zhao Youcai separated the gun from the silencer and said, "Hide it first, this good thing can't be discovered." By the way, it's getting late, and it's time for you to go home! ”

Chu Jiao nodded, you can't become a fat man in one bite, Rome was not built in a day.

Right now, these two pistols equipped with silencers, although they can't make the sound of biu and biu as Shen Chen said, they are already very advanced.

After hiding her things, Chu Jiao drove and pulled Zhao Youcai home. Although Ah Si is loyal, he is not his own person, and it is inconvenient to do things.

Therefore, Chu Jiaocai changed her mind and turned Zhao Youcai into her bodyguard. As for Xie Yuelan, she said to Xie Yuefan that Xie Yuefan sent the brothers in the gang to be responsible for protection.

The host drove the car, and the bodyguard sat in the car, which looked rather weird. Moreover, Chu Jiao is still a woman, which is even more attention-grabbing. Therefore, she wears a hat when she drives out, and it is not easy to distinguish from the outside of the car.

"We should find a place where we can safely test guns." Chu Jiao said in a deep groan while driving: "There are many pedestrians who repair cars, and they are not so safe. ”

"I'm afraid it's hard to find!" Zhao Youcai thought about it and said with some embarrassment: "Out of the concession, it is the territory of the Japanese, and it is difficult to guarantee personal safety, let alone carry a gun, and you have to test it." ”

"I'm talking about the concession." Chu Jiao said: "A house with a basement should be okay, right?" ”

"Even if it's expensive." Zhao Youcai also knew that after the outbreak of the Songhu War, a large number of refugees poured into the concession, including many wealthy people, and the housing prices in the concession skyrocketed.

Chu Jiao nodded. It stands to reason that she is not short of money to spend, but it is not easy to spend a lot of money to do big things, and she has to go through her father.

Back at home, Chu Jiao knew that a man had called to look for her, but he didn't leave his name. She was a little happy, but more annoyed, angry at the guy for hiding his head and tail.
