"This is the first time that the rifle and sniper guns have changed shape, and everyone can feast their eyes on it!" Lei Zhen said.

A slightly thinner barrel rises from the thick barrel, a silver-white sheen with a sense of science and technology that takes on a blood-like red in the slanting sunset.

"Lei Zhen, did you do it yourself? Didn't ask your Aunt Tang for help? If you ask her for help, you have to ask her to say thank you! Tan Xiaolin suddenly said loudly.

"Mom, don't worry, Xiao Yezi stared at me when I made this shot, how could I ask Aunt Tang for help, but Aunt Tang was indeed at the scene at that time, if you don't believe it, you can ask Aunt Tang!" Lei Zhen pointed behind everyone and said.

Everyone turned around, only to see Tang Xinyi standing behind He Zhijun, as if reporting something, seeing everyone looking at themselves, Tang Xinyi nodded at everyone as a greeting.

And the crowd didn't listen carefully to the content of the report, but took the initiative to take two more steps forward, leaving enough space for them.

This is a habit of being a senior special forces, listening to what should be listened to, and resolutely not listening to what should not be heard.

What's more, it's obvious that the gun in Lei Zhen's hand is more fun.

"The barrel of this gun is actually retractable!" Hades' eyes widened.

"That's right, it's an assault rifle in its constricted form, and it's a sniper rifle in its elongated form," Lei Zhen nodded, "That's why it's called a rifle!" ”

"Amazing, doesn't that mean that you can achieve two functions with a gun, why can't I think of such a brilliant idea! Otherwise, I'm the one who is competing with Xiaoyezi now! Tang Ren looked left and right and sighed.

"you, Xiao Yezi is there to compete with Lei Zhen for the gun, obviously for Lei Zhen," Li Ben pushed Tang Ren and questioned, but there was something wrong with the words in his mouth.

"Sanniuzi, if you talk nonsense again, I will throw my underwear on the windowsill of your dormitory and then complain to Uncle He, and let you eat for half a month!" Ye Qingtian said angrily.

"It's still getting longer!"

"It's been so long, it's time to stop, it's all on the same level as the anti-materiel gun!" Yuan Bao exclaimed.

"That's what to do," Lei Zhen smiled, "Let's take a look!" The most complete body of this gun is 10 meters! ”

"Ten meters?! You're a cannon, right? ”

The five-section titanium barrel has been elongated, and the next barrel is starting to turn a little red.

And there are some strange lines on the barrel, which makes everyone a little strange.

Everyone's eyes were sharp, and they soon realized that what was on it was not an ordinary object, but a combination of small pieces of copper, and between the copper sheets there were black silicon wafers that played a sealing role.

It's hard to imagine that this was made by Lei Zhen himself.

In fact, it is difficult for Lei Zhen to imagine that such a large amount of work was completed by himself within an hour, and it can only be said that he is really awesome with system control.

The system is awesome!

"Now the barrel that sticks out is no longer silvery-white, but the color of copper!"

"This is the red copper sheet, because the strength of the titanium alloy is too high, the stress conditions are not suitable for rifling in the rifle state, so I chose the red copper as the material, in order to meet the requirements under the two modes, I made the red copper into such a sheet, using the wedge-shaped structure of the ancient structure to control, to achieve the operation of two caliber bullets compatible at the same time!"

Lei Zhen explained at length, but few people at the scene could understand what was being said here except for Ye Cunxin and Tang Xinyi, two members of the Future War Research Institute.

"Amazing, amazing, Lei Zhen, this kid didn't expect to have this hand, it's really hard work to have such results!"

"Where, where, this is just a small contribution," Lei Zhen said modestly.

The barrel is still growing! It's still growing!

Huge waves, huge waves, continuous growth!

After five minutes, it was finally not long.

"It's ten meters here!"

"That's right, this is the full form of the rifle, the muzzle velocity can reach more than 100 kilometers per hour, and the kinetic energy contained in it can already avoid most air disturbances," Lei Zhen explained.

As long as the speed is fast enough and the kinetic energy is large, the air disturbance can be ignored.

"Awesome!"

"Awesome!"

"Brother Zhen, hurry up and let us see how awesome it is!"

Cai applauded in his heart and made some cards for Lei Zhen.

"Wait!" Lei Zhen scratched his head, "After all, time is limited, and I personally can't polish the lenses myself, so I still have to borrow your sniper goggles." ”

"Here you go!" Ye Qingtian's eyes straightened when he looked at the ten-meter-long sniper rifle, "Let me see if it's easy to use!" ”

"By the way, if I use this 12.7mm caliber bullet, will it cost me? I don't have so much living expenses as Miss Ye! Lei Zhen said.

"If you can win me, I'll give it to you, and if you lose, watch it yourself!" Ye Qingtian squinted.

Lei Zhen squatted down with a ten-meter-long rifle and sniper gun, looked at the sniper scope in a half-kneeling position, and found a balloon.

Press the trigger!

Tang Xinyi whispered to He Zhijun: "No. 1, you see, this is the infantry and sniper dual-purpose gun that Lei Zhen made himself." ”

"You're saying he did all the work himself?" He Zhijun raised his eyebrows and said.

"Yes, all the processes, I watched him start processing from one pipe to another, and the thing he made," Tang Xinyi chiseled.

"So what's so exciting about you?" He Zhijun asked, "At present, I don't see that there is such a factor, it's a bit like a child's play, the ten-meter-long barrel is simply unreasonable." ”

"What if it's a foldable three-meter barrel?" Tang Xinyi said leisurely, "For many anti-materiel weapons, large size has always been a very big difficulty...... This is also a question that we at the Institute for Future War Studies have been researching, and this kid Lei Zhen has inadvertently opened a door to portable counter-materiel weapons for us. ”

He Zhijun is not a stupid person, he has already understood Tang Xinyi's train of thought when he heard this.

"This thing can't just flow out casually...... He Zhijun said in a low voice, "Fortunately, it was Lei Zhen who made this, and we can make it clear to him calmly, if it is someone else...... Tsk, the consequences are unimaginable. ”

Large!

The sound of vigorously tearing the silk made He Zhijun's heart tremble.

Burst!

As soon as the words fell, a crisp balloon burst sound was heard in the distance.

Just the first bullet is amazing enough.

There was a chaotic sigh from the onlookers in the distance, and He Zhijun saw that Lei Zhen was bounced away from a distance and smashed on the ground.
