"Yo? What new stuff have you made?"

Seeing the crossbow playing with Lu Yu's hand, Ye Ziqing walked over with breakfast curiously.

"Bow and crossbow." Lu Yu smiled.

"What?" Ye Ziqing widened her eyes in surprise: "You are bored, have you tinkered with cold weapons?"

"Don't underestimate it, this is not an ordinary crossbow..."

Next, Lu Yu introduced the function of the black technology crossbow, and the latter looked incredible.

"Are you serious? This little tool has such powerful abilities?"

Ye Ziqing asked in shock while covering her mouth.

A crossbow actually has the ability to recycle, which is so terrifying!

Lu Yu said lightly: "Actually, the principle of this crossbow and an electromagnetic rifle is similar! But the kinetic energy of the bullet is too great and the shooting is farther than that of the crossbow arrow, so it cannot be recycled. However, the speed of the crossbow is far lower than that of the bullet, and it cannot be so far in the later stage, so there is no problem in recycling."

"In addition, this crossbow is very suitable for close combat. It can fire three arrows at the same time. If the enemy fails to react, it will be killed. It is invincible in melee combat!"

"It is suitable for special forces' infiltration and reconnaissance behind enemy lines. In addition, when the special police rescue hostages, this thing is much better than a gun and faster!"

Lu Yu said loudly.

"Is it so magical?"

Ye Ziqing curled her lips and put the breakfast on the table and said, "Don't just listen to you brag alone. The key is whether it is so powerful in making it?"

Lu Yu laughed: "You just wait and see, its function will only be better than what I said!"

Ye Ziqing nodded: "If I really want to be as you said, I will be convinced by you!"

The breakfast served by Ye Ziqing was quite rich.

Maybe because Lu Yu has been tired from working overtime all night these days, he also has a can of fragrant chicken soup to nourish his body.

Lu Yu didn't ask who made the breakfast either.

When he thought, who else was so considerate besides his wife Anran?

Seeing Lu Yu finish all the chicken soup, Ye Ziqing showed a satisfied smile on her face.

This is the chicken soup she made with her own hands when she got up early this morning.

Seeing that Lu Yu worked so hard yesterday, he wanted to make up for him.

"Thank you for my wife for me, the chicken soup tastes good."

Lu Yu drank a bowl of chicken soup and placed the bowls and chopsticks on the tray.

"Hmph, you only have your wife in your heart!"

Ye Ziqing glared at Lu Yu and left angrily with the tray.

Today is Tang Xinyi coming to duty, so she has to go back and rest quickly.

"This girl, have I offended her again?"

Lu Yu shook his head and muttered, then continued to bury his head, and stepped up his efforts to follow up the production of the crossbow.

Below, two sensors must be installed for the crossbow.

Lu Yu immediately started making it.

The sensor has been used very well in the electromagnetic rifles and helicopters at the time, and this technology is easy to use for Lu Yu.

In addition, the two sensors installed on the crossbow are not as complicated as those on the rifle.

It took only more than an hour to design the two micro sensors successfully.

It was built in strict proportions. By the afternoon, he finally fixed the two finished devices in the weapon groove of the crossbow.

After the crossbow and the sensor are connected, the next step is to turn on the power supply.

At the tail of the crossbow, a battery box is specially designed, and like an electromagnetic rifle, it uses a blade battery.

Not only is it sufficient electricity, it is also explosion-proof and high temperature-proof, and even if water inlet, it will not cause leakage.

In addition, there is solar charging technology.

As long as you use sunlight, you can automatically store electricity without worrying about insufficient electricity.

After another busy day, at night, this black technology crossbow finally took shape.

Lu Yu found a wooden stick for experiments.

He tied a small piece of metal to the top of the stick.

Metals and electromagnetic devices induce, which immediately creates a dark connection.

Lu Yu casually aimed at a target on the wall and pulled the crossbow trigger.

With a swish, the wooden stick instantly bounced out and hit the target.

Then, Lu Yu pressed the button on the crossbow, and because the distance was not more than twenty meters, the wooden stick was magically summoned back by the electromagnetic device.

Holding the wooden stick, a faint smile appeared on the corner of Lu Yu's mouth.

This is his first time trying. If he practices a few more times, he can automatically fly back into the quiver.

In this way, you need to catch the crossbow arrows yourself, and the frequency of shooting archery with both hands will be faster.

“The effect is pretty good!”

Lu Yu was very satisfied with the performance of this crossbow, although it still looked ugly.

This crossbow is compact and easy to carry. It can be used with hand-held speed and can completely cause uninterrupted firepower attacks.

He can be said to be the absolute king on the melee battlefield and the invincible master!

Especially modern people will not practice avoiding shooting of crossbows like in the cold weapon era.

When it comes to the powerful attack of the crossbow arrow, there is almost no power to fight back.

"Next, continue to create a few crossbows and then create crossbow arrows for shooting."

Lu Yu did it as soon as he said it.

However……

Just as he was about to make the next crossbow, he caught a glimpse of the wall that had just been hit by a wooden stick.

Although there are no arrows installed on the wooden stick, only metal blocks are tied.

But under the strong kinetic energy, a small hole was directly sunk on the hard wall.

Lu Yu was shocked and hurriedly ran over to watch carefully for a while, and suddenly realized a possibility.

Although I created a powerful crossbow, I didn’t seem to have made any preparations in terms of defense!

Those who followed him were still very fragile and dangerous.

Although most people have injected super genes to improve their physical fitness, the ability they have obtained is less than one percent less than Lu Yu.

No one can have an invulnerable body of steel like Lu Yu!

With Lu Yu's current fusion of steel body, it is no problem to reach more than ten heavy machine gun bullets.

If it were someone else, let alone heavy machine guns, an ordinary person would die immediately if he snatched a bullet and hit the body with an ordinary person.

Lu Yu frowned: "I don't know what the defense system in the fifth area is, but since it is Lao Mi's heart, the defense there must not be underestimation. It is inevitable that a close encounter will occur..."

Thinking of this, his expression gradually became serious.

If you meet in a small space, you will not be afraid of his defense, but others will be unable to escape if they are hit.

Maybe, because of my carelessness, everyone was wiped out!

"No! You have to find a way to improve everyone's defense, otherwise it will definitely not work if you have weapons but no protection."

Lu Yu lowered his face and immediately searched for Iron Man's weapons knowledge in his mind.

Soon, I found the memory of this aspect, all about the protection system.

The most advanced protection is of course the Iron Man Mark armor, but it involves nanotechnology.

This kind of high-tech black technology is difficult to realize at one time for Lu Yu.

It’s not that Lu Yu can’t make it.

But there are too many machines missing.

A good cook cannot cook without rice!

With the current domestic technological level and field, without corresponding supporting technology, even if the design drawings are drawn, there is definitely no way to manufacture them.

Basic science and manufacturing industry cannot keep up, and everything is useless.

Therefore, Lu Yu found the only effective protection method that applies to these memories.

Titanium Bombproof Vessel!
Chapter completed!
