The variable barrel is the most difficult to achieve on the entire drawing, and although the wedge-shaped structure is ancient, it is a wonderful structure that can only be made by the most skilled craftsmen in ancient times.

Is it okay to thunder quake?

Originally, Tang Xinyi didn't believe it, but the skillful movements before made Tang Xinyi have to believe that this kid really has this ability.

The difference between the standard 7.62 mm caliber and the 12.7 mm caliber of tungsten carbide bullets is huge, and in order to be compatible with the two modes, the barrel is definitely sporty, but it must be tight, not a little worse.

I saw Lei Zhen carefully arrange the metal pieces, and then weave them together, making them staggered, layer by layer.

"This is the barrel? What should I do if there is an air leak? Ye Qingtian leaned on Tang Xinyi's shoulder and watched the thunder shock operation on the screen.

"This is rifling in rifle mode," Tang Xinyi said, "in sniper mode, this becomes an extension of the barrel again, as long as the craftsmanship is done properly, it will not leak." ”

"Oh, that's it......" Ye Qingtian looked confused.

Through the glass, I heard Lei Zhen downstairs let out a triumphant laugh: "Hahahahaha!" That's it! ”

I saw Lei Zhen find two compressed air cylinders and put them on both sides of the rifle, and raised them: "Perfect!" ”

"That's it?" Ye Qingtian looked at the time again, an hour was just right.

"This should be over, let's go down and see the results," Tang Xinyi couldn't wait to push open the door and go downstairs, walking quickly.

She really wanted to see the true face of this sniper dual-purpose gun for the first time!

Downstairs, I saw Lei Zhen carrying two cylinders on his back, and then connected to the gun with a hose.

"Aunt Tang!" Lei Zhen saw Tang Xinyi coming down, and responded politely, "Look at this gun, it's good!" ”

"I have a small question, are you going to snipe with me with such a cylinder?" Ye Qingtian also came down, and he was really happy to see this scene.

"Time is urgent, I can't make the small air compressors that were originally planned to be placed on these sides," Lei Zhen said, "Replace them with big cylinders first!" ”

"Lei Zhen, give me this blueprint, I'll help you with the staff staff, what do you think?"

"Then thank you Aunt Tang! But now, let's compare the said good test first, otherwise the thoughts of our first beautiful girl with wolf teeth will be concerned about me, and it will be the most difficult to accept the grace of the beauty......"

Lei Zhen walked out as he spoke, and the words in his mouth were so angry that Ye Qingtian jumped three feet high.

"Accept your sister, grace your sister," Ye Qingtian scolded and said, "How do you know if you can use it if you don't test it?" ”

"I know it in my heart," Lei Zhen thought to his head, "I was completely prepared when I designed it!" This is called the success of successful people! ”

"Cut!"

On the playground, Chen Xinzhe, Cai Congxin and a vote of soldiers were stretching their necks in anticipation.

Even the new fighters who had just entered the wolf's tooth knew the beginning and end of this duel under Cai Congxin's enthusiastic gossip, and they became more and more curious about characters like Ye Qingtian.

And the old soldier with wolf teeth was also quite curious about what kind of Lei Zhen and Ye Qingtian would make.

Especially what kind of thing Cai Congxin said that Lei Zhen wanted to DIY himself.

"Dazhe, what did you ask me to come out for, and you pulled so many of your uncles and aunts out together, I still have to write a review, No. 1 is very angry, and the consequences are very serious! Originally, there was a 2,000-word review, but you didn't wake up for a long time, so you directly added 20,000 words to No. 1! ”

Hades said with a look of grievance.

Behind Hades, the Thunderbolt Commando, the former Blood Cell, and a group of female warriors of the Fire Phoenix all came.

Cai Congxin directly called the master he had just recognized, and the two stood one after the other as if they were father and son.

Yuan Fen followed behind Yuan Bao with a sweaty face, looking unhappy.

He felt uncomfortable when he saw Cai Congxin and Chen Xinzhe coming, this was obviously a scenery scene prepared for Lei Zhen.

As a result, I was rubbing the air conditioner in my father's room at the time, and I was dragged together.

quietly asked Cai Congxin, and the answer he got was even more troublesome than he imagined.

The two people in PK are Lei Zhen and Ye Qingtian.

I thought there was only one child from someone else's family, but now it's two!

I don't want people to live!!

Lei Zhen is already very excessive, Ye Qingtian has grown up listening to legends since he was a child, and Yuan Fen, who is harmful, will tremble when he hears this name.

As a result, you tell him that this time you have to watch them pretend to be X!

it!

"Come on, I've seen Brother Zhen!" Cai Congxin suddenly screamed, and this cry shocked everyone's spirits.

On one side is the first beautiful girl with wolf teeth, Ye Qingtian, who combines beauty and strength.

On one side is the son of Lei Zhan, who claims to use a rifle to hit a thunderbolt against over-the-horizon targets.

Lei Zhen held the rifle with both hands, and the barrels of the two heads were particularly eye-catching.

At first glance, everyone saw the two metal cans that were larger than watermelons on Lei Zhen's back, and they were a little confused.

What the hell is this, spraying pesticides?

"Eh, brother. Lei Zhen tinkered for an hour to make such a thing? A wolf-toothed warrior said.

"I don't know, Brother Zhen just asked me to come over and call you, and I don't know anything else," Cai Congxin hurriedly said.

"The gun he said should be the iron bump on his waist, it's so thick, could it be an RPG launcher?"

"According to Brother Zhen's character...... Maybe......" Cai Cong thought about it and said with a wry smile.

Lei Zhen doesn't like to play cards according to common sense, and it's not impossible for him to get an RPG to fight.

"Cai Congxin, are you talking bad about me again," Lei Zhen had already heard the voice and said loudly.

"Brother Zhen, everyone is in a hurry, you are still so leisurely, everyone tell me what's wrong with you?" Cai ran to Lei Zhen in a hurry, "What is this thing?" Could it be an RPG launcher? ”

"Do you follow their?" Lei Zhen glanced at Cai Congxin, "This is a rifle and sniper dual-purpose gun, so that the shrinkage mode can be loaded through the magazine, and after elongation, only one bullet can be loaded at a time, and the bullet is sent from the feed port here, which is adapted to the domestic 8.6 mm caliber bullet." ”

"Rifle and sniper?" Hearing this, Hades raised his eyebrows, "It's kind of interesting!" ”

"Don't get in the way, you kid," Ye Qingtian raised the butt of his gun and made a gesture to smash, "We're very busy, don't get in the way!" ”

"Hey, as a girl, you should be gentle," Cai Congxin cried out with his head in his hands.

"Gentle? Eat gently! Ye Qingtian was really about to smash it, Lei Zhen hurriedly stretched out his hand to stop him, "Brother cowardice has PTSD, if you really smash it, he will be sick in this life, you will raise him!" ”

Ye Qingtian looked up and down at Cai Congxin, who was on the side: "It's not easy, what have you experienced, you actually got such a miserable illness." ”

"And ...... It's none of your business! Cai Congxin hurriedly walked behind Lei Zhen.

"Say!" Ye Qingtian glared, and the butt of the gun was raised again.

Cai Congxin hurriedly glanced at Ye Cunxin, but she didn't look at this side at all, muttering to Lei Zhen and her mother.

I'm afraid that even if I saw it, I wouldn't say anything.

"Okay, my dad forgot about it in the dung pit......" Cai Congxin whispered.

"I'm sorry for you......" Ye Qingtian pursed his lips, and suddenly regretted why he asked this question, he was full, right?

"Don't make a fuss, let's start quickly, it's hot," Tang Ren said with a smile, and Lei Zhen noticed that everyone in Poseidon's team was actually there.

"Ye Qingtian, your influence is really big enough, two generations of falcons are shocked together!" Lei Zhen smiled.
