Spending money to let the system give him a haircut, a facelift, a shortening, and a return to his mentality, after Chen Yu thought about it, he entered his personal space and looked at the huge big black, he planned to charge it with some money.

"Master." Shenlong Xiaojin ran over happily.

"Xiao Jin, you seem to have grown a little longer." Chen Yu said with a wicked smile.

"Master, where did I grow?" Xiao Jin hurriedly shook his head and denied it.

"You've grown at least two centimeters." Chen Yu said with a determined expression.

"Master, how big do you think the big black is? How mighty is it? I've been wronged enough, as a five-clawed dragon, it's only so big, woo woo. Xiao Jin squeezed out a few dragon tears and said pitifully.

"Forget it, if you grow, you will grow." Chen Yu said.

"Master." The star-swallowing beast with a body length of more than a thousand kilometers shouted loudly for nine days.

"Da Hei, how are you practicing your dragon technique?" Chen Yu asked with a smile, the reason why Star Swallowing Beasts can swallow stars, in addition to spatial talent, the most important thing is that they are huge, and some Star Swallowing Beasts are tens of thousands of kilometers long.

"Master, I'm already getting started." Daikoku said happily.

"When will you be able to transform?" Chen Yu asked again.

"Maybe in a few hundred million years, I will be able to transform." Da Hei said seriously.

After Chen Yu thought about it, he began to charge Da Hei with money, and after tens of billions of cosmic coins, the other party reached the demon infant stage.

Da Hei's body changed, and a burly, strong man with no wisps on his body appeared in front of him.

Chen Yu frowned and said, "Change back to your original appearance and reduce your body size as much as possible." ”

Da Hei nodded, and turned into a Star Eater again, but at this time, it was only a little more than a meter long.

"Not bad." Chen Yu nodded with satisfaction.

"Big black, hahahahaha." Jin couldn't help but laugh.

"Brother Long, what are you laughing at?" Da Hei asked dumbfounded.

"Big black turns into little black, it's so funny." Xiao Jin said with a smile.

After playing with Xiaojin and Da Hei for a while, Chen Yu left his personal space, and seeing that the sky was getting brighter, he put away the stand-in robot, lay down on the bed and fell asleep, until his mother shouted for breakfast, he didn't get up from the bed.

After breakfast, he returned to the room again, sat in front of the computer, and with the help of the intelligent system, he began to make the production materials of helicopters, passenger planes, high-speed rail, large excavators, shield machines and other machinery and equipment.

"After the sniper rifle developed by Wang Mingchuan was accepted by the military, he began to manufacture helicopters."

"There is too little land, and we have to let Wu Zhenshan buy some land, there are more and more factories, and the existing land is far from enough."

"High-speed rail can be made in advance, and it is more convenient to travel in the future, after all, high-speed rail is safer than airplanes."

This morning, Chen Yu rode a bicycle to the Fujishan Industrial Park.

"Director Chen, you're finally here." Wang Yonghua, who was standing at the gate of the factory, shouted with a smile on his face.

"Someone from the military is coming?" Chen Yu asked thoughtfully.

"Well, Captain Yu, they've arrived." Wang Yonghua said.

"Okay, I'll go in first." Chen Yu nodded and rode his bicycle into the factory.

"Director Chen." Wang Mingchuan, a weapons expert, shouted respectfully.

"Director Chen, this sniper rifle has an impeccable look and feel, but I don't know how it performs?" Yu Jianjun said with a smile.

"Find a place to try, won't you?" Chen Yu said with a smile.

"Well, I'll be waiting for you." Yu Jianjun said.

The group took three sniper rifles, several boxes of armor-piercing bullets, sniper bullets, and high-explosive shells, and left the factory in a military vehicle.

"I'll try it first." Yu Jianjun picked up a sniper rifle, skillfully loaded the bullet, and aimed at a target 100 meters away.

"It's not a pistol, it's a sniper rifle, okay? Let's start with a kilometer. Chen Yu said.

"Okay." Yu Jianjun nodded, aimed at the target thousands of kilometers away, and after adjusting his breathing, he pulled the trigger.

Gunshots rang out, armor-piercing bullets burst out, and the metal target in the distance was pierced by the bullet.

"The marksmanship is not bad." Seeing that the other party had hit a nine ring, Chen Yu praised with a smile.

"Director Chen, can you see so far?" Yu Jianjun asked suspiciously, how could the other party see the situation on the target a thousand meters away without using a telescope?

"I have better eyesight." Chen Yu said with a smile.

"Director Chen, can you really see so far?" Yu Jianjun asked again.

"Isn't it just a nine-ring? It's still a stationary target, and if you want me to come, the gun is fine. Chen Yu said.

"Come, I want to see, how do you shoot ten rings?" Yu Jianjun questioned.

Taking off the scope on the sniper rifle, seeing that everyone looked puzzled, Chen Yu said, "This thing is too much of a hindrance." ”

"Don't say so much, let's start fighting!" Yu Jianjun couldn't wait.

Chen Yu picked up the sniper rifle, and after aiming quickly, he pulled the trigger without hesitation.

"Bang bang......" bullets shot out one after another, and the center of the target thousands of kilometers away was shot into a circle by the bullets.

"Zhang Manjiang, the sharpshooter of our military region, has always been angry, and his marksmanship is many times worse than yours." Seeing that the opponent's gun hit the bull's-eye, Yu Jianjun said in disbelief.

"Basically meets the design requirements, this sniper rifle, should be able to meet the requirements of your military, right?" Chen Yu asked with a smile.

"I heard that this sniper rifle is designed to have an effective range of up to 3,000 meters, is it true?" Yu Jianjun asked.

"It also depends on who uses the gun. Sniper bullets must also be used. Chen Yu said.

"If you use it, can you hit 3,000 meters?" Yu Jianjun asked.

"It shouldn't be a problem." Chen Yu said.

"Can you open our eyes?" Yu Jianjun asked again.

"You don't seem to have a target here that is 3,000 meters, right?" Chen Yu asked with a smile.

"Zhang Jin." Yu Jianjun shouted.

"Here!" A soldier ran over.

"Go get a three-thousand-meter target." Yu Jianjun said.

"Yes!" Zhang Jin nodded in response, took a target, and ran quickly into the distance.

Ten minutes later, Yu Jianjun said, "Director Chen, it's time for you to perform." ”

Chen Yu put on the scope, looked at the target, and after aiming, the muzzle of the gun moved a little to the upper left, and then pulled the trigger.

The gunshot rang out, and a sniper bullet flew out quickly, and the constantly rotating bullet began to deflect to the lower right.

In the center of the target three thousand meters away, there was an extra hole, and Yu Jianjun said incredulously: "You can also hit ten rings here?" ”

"When I was designing this sniper rifle, I studied the trajectory of the bullets...... Chen Yu said casually.

"Director Chen, when you have time, can you come to our barracks to give a lecture?" Yu Jianjun asked expectantly.

"At that time, I might as well go and develop a gunship." Chen Yu said.

"That's just as well." Yu Jianjun said with gains and losses.

"By the way, is this sniper rifle produced by your military factory, or are we producing it?" Chen Yu asked.

"You're willing to let our arsenal produce?" Yu Jianjun asked curiously.

"If your military factory is willing to produce this sniper rifle, we will hand over the relevant technical information to you, and if you are not willing to produce it, our factory will produce it." Chen Yu said nonchalantly.

"I'll ask for instructions from above, and I'll reply to you within three days." Yu Jianjun said.

"Okay!" Chen Yu nodded, and said, "I plan to develop helicopters and high-speed rail...... The relevant procedures should be completed as soon as possible. ”
