Chapter 894: The High-Tech Crossbow Comes Out

In addition to the black technology crossbow, Lu Yu also designed a new type of dagger.

The dagger is one of the cold weapons used by the special forces for the longest time, and it is also the weapon that Lu Yu is best at using!

In close combat and stealth combat, the dagger is the easiest to quickly kill the opponent.

Like the black technology crossbow, Lu Yu also redesigned the dagger, and there are two styles.

The first type of shape is relatively small, suitable for use as a finger knife.

Because of its small size, a belt can be specially designed for large-scale carrying.

Similarly, it is also suitable for use when flying to take the enemy's head thousands of miles away.

The belt will also be equipped with an electromagnetic recovery device, as long as the throwing knife is pulled out and locked electromagnetically, it can hit the target 100% of the time.

Of course, because of the summoning device, all the flying knives will be recovered and recycled.

The second type of dagger is no different in size from ordinary daggers.

But Lu Yu installed a laser device, and there will be a special button on the handle of the knife.

Just press the button and a laser will shoot out from the front of the blade.

This laser can easily cut steel plates up to 50 centimeters thick, making it invincible.

Even in the face of heavily armored tanks, it will be as easy and casual as cutting tofu.

However, the only difficulty is that the requirements for the laser device will be very high.

With the current scientific and technological strength, it cannot be manufactured, so Lu Yu can only redesign and create a laser device.

In addition to these two, there is also a new high-explosive explosive.

On the basis of the original, this explosive has undergone polymer rearrangement to achieve high concentration and saturation of energy.

It only needs the size of a pigeon egg, and the energy it releases is equivalent to hundreds of grenades exploding at the same time.

Small in size, but very powerful and easy to carry.

Looking at the design drawings of these weapons in front of him, Lu Yu carefully revised them one by one.

It wasn't until early in the morning that he put down all the drawings and let out a long sigh of relief.

Now, the design drawings have all been done, just waiting for the next step to be put into production.

Boom!

Suddenly there was a knock on the door.

Lu Yu walked over to open the door and found An Ran: "It's so late, why haven't you gone back?"

Looking at the time, it was already half past two in the evening.

An Ran showed a soft smile, but couldn't hide the tiredness on her face: "Didn't I wait for you to go back together? I stayed outside for more than three hours. I only came to call you when I saw you were busy. You didn't even notice it yourself. , haven’t been home for a long time?”

Looking at the smile on An Ran's face, Lu Yu was filled with emotion and hugged her.

"Okay, let's go home together!"

...

Going home this time, Lu Yu stayed with An Ran for a day and two nights without leaving home.

As for what the two of them were doing at home during this period of time, only they themselves knew.

On the morning of the third day, Lu Yu took An Ran's hand and returned to the military factory research institute with a red face.

"I'm going to make a new weapon in the past two days, and I can't go back."

Lu Yu stretched out a hand, caressed An Ran's face and stared at her: "After you finish your work, you can go back to rest early by yourself, you don't have to wait for me, you understand?"

"Um!"

An Ran nodded docilely: "You work at ease, I will definitely not bother you! I will be on duty in two days, and I will accompany you at night."

Lu Yu smiled and patted the latter's head before turning around and walking into the laboratory.

Originally, time was tight, and Lu Yu spent a day and two nights with An Ran because he felt that he owed An Ran too much.

So, give a little compensation within the scope of your ability.

After explaining things well, he can devote himself wholeheartedly to weapon research.

Entering the laboratory, Lu Yu spread out all the design drawings one by one.

Although the weapons designed on each blueprint are different, there are many similarities among them.

For example, the weapons are mostly made of the same material, a high-strength titanium alloy.

This composite material is extremely stable, and it is not easy to deform in various environments, and it is specially used for the protective coating of helicopters.

Moreover, it has very high-strength high-temperature and low-temperature resistance properties, and its toughness even exceeds that of the hardest steel in the world.

Lu Yu first synthesized a large amount of titanium alloy materials to prepare for the manufacture of weapons.

Next, start building the first black technology crossbow.

The first step is to customize a one-to-one crossbow model. Only when the real thing is built can the problem be found.

Although the drawing is drawn, it is only a floor plan.

Whether the size is suitable or not, how it feels to use, etc., depends on the actual product.

At first, Lu Yu had to build a mold and have all the details specified.

It took a whole day for Lu Yu to basically complete the model.

This is only done when he practice makes perfect and with the help of the machine.

After the mold cooled, Lu Yu placed it under a high-power microscope and polished it meticulously.

Although it is a crossbow, it is not an ordinary crossbow, and it is a combination of cold weapons and modern technology.

This is a new and bold attempt. Whether it can be successful or not depends on how much Lu Yu spends on it.

Any small flaw may cause the weapon to be scrapped and eventually affect its use.

Every step of Lu Yu was very careful, as if carefully polishing a work of art.

Even if the design of a place is flawed or inaccurate, mistakes will occur and even cause casualties.

Therefore, we must wholeheartedly, not the slightest sloppy.

Boom!

Some time later, there was a knock on the door outside the laboratory.

The door was pushed open, and Ye Ziqing walked in with a tray.

"It's so late, are you still busy?"

The latter put the tray in front of Lu Yu, with some fruits and milk on it, and a bowl of fragrant noodles.

"Here, I'll reward you for seeing you work so hard!"

Lu Yu smiled: "I can't tell, are you here to give me warmth?"

Ye Ziqing curled her lips: "Don't make up your mind! This is what An Ran's sister-in-law ordered. She just came back from get off work, and I happen to be on duty today!"

"Okay, thank my wife for me." Lu Yu chuckled: "It's still my wife who loves others!"

The two chattered a few words, and Ye Ziqing continued to go out to be on duty.

Lu Yu ate and drank enough, but he became more energetic, and started working at full speed overnight.

Now that the model has been made, it will be much easier to make a bow and crossbow.

In the middle of the night.

In the laboratory, there was the humming sound of various machine tools working.

It lasted until the next day when the sound of the roaring machine gradually stopped.

And in Lu Yu's hand, he also succeeded in having a prototype bow and crossbow.

Of course, this is just a prototype, it looks dark and has not been carefully processed.

Next, as long as it is polished carefully and installed with electromagnetic devices and thermal induction devices, the crossbow will have extremely strong lethality.

crunch!

Just in time, Ye Ziqing came in with breakfast, and was surprised when she saw the crossbow.
