The vast majority of men in the world like to "shoot" two things, one of which is a lethal firearm.

What Yang Xiu wants to make is a machine with great lethality, of course, not a firearm, but a mechanically powered bow and crossbow.

The reason why he chose to major in mechanical and power engineering is that he likes machinery, and once secretly made a 51 pistol, which was melted into molten iron immediately after it was made, this kind of thing is not difficult to make, but the difficult thing is ****.

After this thing was discovered, he could get a pair of iron bracelets for free, and he didn't want to spend his next life with a group of big men.

The pistol is not as good as the bricks without bullets, so Yang Xiu does not plan to use the weapon, but to make a bow and crossbow that makes it easier to obtain arrow feathers.

In fact, if he could shoot arrows, he wanted to make a compound bow and arrow, which could shoot through a cow in a short distance, which even ordinary pistols could not do, and you can imagine how terrifying the lethality of this compound bow and arrow is.

He didn't know how to shoot arrows, and the kind of bow and arrow was very heavy, not easy to carry, and there were no special materials, so it was better to make a light bow and crossbow to wear on the hand.

He studied all these things when he was bored in college, and kept them in his head.

The small engine made a rumbling sound, all kinds of machinery were running, the temperature in the room gradually rose, the red molten iron was bubbling, all kinds of simple molds were generated, and time passed little by little, and the sweat wet Yang Xiu's back, as if falling into the water, and the sweat dripped on the hot iron, making a sizzling sound.

After a few hours, all the parts needed for the bow and crossbow are made, and then it is easy to assemble them, which is fixed by electric welding.

Soon, a crude composite bow was made, about twenty-five centimeters long and weighing about ten pounds, with beautiful grooves wide enough to hold arrows a finger thick, and easily accessible steel nails.

Put it on your left arm, pick up a steel nail and snap it into the crossbow, and come to the window.

Looking out, a bunch of zombies gathered under this floor, gnawing on the corpses on the ground in groups of three or five, extremely bloody, Yang Xiu was sick to his stomach for a while, and he was more afraid, if so many zombies broke in, they couldn't stop it at all.

Some zombies have their intestines on the ground, some zombies have lost half of their heads, and some zombies are very faceless and undressed, which is disgusting.

"Why are there so many zombies gathered outside this building?" Yang Xiu looked out the window curiously, there were many zombies outside his building.

Suddenly, he thought of something and looked at the engine in the room.

The world without human activity became extremely silent, only the roars of zombies and the sound of generators were extremely harsh and obvious.

Could it be the sound?

Thinking of this, Yang Xiu walked to the generator and turned off the generator, and slowly, these zombies wandered in confusion and gradually dispersed.

Yang Xiu was sure that it was indeed a problem with the voice, and silently remembered the habit of zombies.

Raise your left hand and aim your crossbow at the zombie below.

"I'm sorry, you've lost consciousness, the antidote says that it's impossible to recover if you become a zombie, if you are conscious and don't like to become these ugly things, I'll help you get free."

Zombie: I think that's good.

Aim the crosshair at the legless zombie lying on the ground below and pull the trigger.

With a bang, the steel nail disappeared from the bow and crossbow, and plunged straight into the concrete ground in front of the zombie, but did not hit the zombie.

Yang Xiu's heart was shocked, it was so lethal that the cement floor was broken.

He stuck a steel nail in the crossbow again, continuing to aim at the creeping zombie's head.

"Puff~"

The iron bar hit the body of the zombie, and the black disgusting liquid flowed out, but the zombie was still crawling, and the injury had no effect at all.

It seems that it is really like the other side in the movie, only by blowing the head out.

Yang Xiu pondered.

After several attempts, he finally shot the zombie in the head three times in a row, and the poor zombie was completely motionless.

Immediately afterwards, Yang Xiu began to test the effective range.

After a few minutes, a certain amount of data was obtained, and the effective range was about 20 meters, beyond which the arrow would lose its accuracy and lethality.

However, Yang Xiu is still very satisfied, with this thing, he can directly explode the zombie's head, the disadvantage is that the material of **** is not very good, the bow and crossbow only have a lifespan of about 100 times, and it will be scrapped after this value.

But that's enough, and he doesn't go out, as long as he stays for three days and waits for the army to arrive, this thing is dispensable.

This thing is a psychological comfort, anyway, there is a high top.

When I join the army, I will find an opportunity to operate and let them contact the army in the north and ask my sister about the situation.

But immediately, his dry throat made his face distort.

Several hours of high-temperature and high-intensity work made the water in his body evaporate extremely quickly.

Just then, a glass of water was handed to him.

"You're really a mechanical genius." Ma Yuan's beautiful eyes stared at the bow and crossbow on Yang Xiu's left arm, her beautiful eyes flickered, "By the way, why can your left hand move?" ”

Yang Xiu did not take the water in Ma Yuan's hand, but looked out the door, looking for the figure of the fat man Li Ruiming.

Li Ruiming lay weakly next to the water dispenser, hungry and kept pouring water from the water dispenser into his mouth.

Ma Yuan whispered, "Don't worry, that fat man has been drinking for five or six hours, according to the news on the news, infected zombies will mutate in an hour at the latest, and it has already passed that time, so I am sure that the bucket of water is not poisonous...... You're really ruthless, take the two of us as an experiment to see if the water in the water dispenser can be drunk. ”

Ma Yuan saw something.

Yang Xiu still didn't catch the water cup, walked outside the mechanical room, and took a few cups by himself with a disposable paper cup and drank it in a big gulp.

When the thirst subsided, he picked up the tomato sauce cup from the ground and filled it with a glass of water, returned to the mechanical room, and continued to work.

In addition to special arrows, there are several important things he wants to make.

Seeing that he was being ignored and the ups and downs of the mountain peaks, Ma Yuan wanted to open his mouth and scold, but he thought of something, he didn't scold, closed the door, slowly took off the experimental clothes on his body, walked to Yang Xiu's side, and slowly hugged Yang Xiu.

A gentle and charming voice sounded, "I looked at the leftover packaging in the kitchen, there is a bag of instant noodles missing, you now have at least one bag of instant noodles, is it okay for me to eat, as long as you promise to do me a favor again, I will promise you everything......"

"Your husband just died and can't wait to cuckold him?" Yang Xiu was calmly making things, his words could not be described as non-poisonous, directly attacking his character.

Sure enough, Ma Yuan's face became extremely ugly, and she didn't react for a long time.

Ma Yuan let go of his hand and looked at Yang Xiu with a cold expression, "Now give you a chance, give me food, and do me a favor, otherwise the army is coming, and I have the ability not to let my father take you away." ”

Yang Xiu, who was making machinery, paused.

Ma Yuan stared at Yang Xiu's back tightly, sweat dripping from her hair, she seemed to be nervous about something, and her breath was unconsciously held, waiting for Yang Xiu's answer.

Yang Xiu, who was silent for several minutes, slowly took out a bag of instant noodles from his arms and threw it to Ma Yuan, "This is the last bag, save it and eat it, and stick to it for three days." ”

This is the result of weighing the pros and cons, Yang Xiu is not arrogant enough to think that he can survive alone in the end of the world, and can only rely on the army.

Zhang Zhe's strength increased by two to three times yesterday, and this thing was still in groups, so it was impossible for him to beat it.

In addition, he also planned to ask his father to help contact his sister in the northern army through Ma Yuan's connections to find out the situation.

But he just gave her a bag of instant noodles, and the piece of meat had to be hidden just in case.
