Weapons are an extension of limbs, and humans don't have sharp claws, but with weapons, they can turn beasts with sharp claws and fangs into food.

Now, Yang Yi is that person, and the boxing king is that beast.

So Yang Yi needs weapons, and he needs weapons very, very much, but he doesn't have weapons and he doesn't have a way to get weapons, so ...... It's a big deal to make it yourself.

Being a garbage handler is the most convenient way for Yang Yi to get weapons, if he can't get a job as a garbage collector, he will naturally think of other ways to get weapons, and being able to get garbage is just the most convenient and trouble-free way.

Packed up the few things he had prepared, and after the preparation was completed, Yang Yi took a big shovel-like shovel and began to clean up the dirt on the shovel, he wanted to make the shovel as clean as possible.

Chris swallowed and whispered, "Can you use the drink bottle, it will become very brittle after melting and hardening, and it won't be easy to use, right?" ”

Yang Yi smiled, and then he said confidently: "There are many kinds of plastics, not all plastics will become brittle after melting and hardening, at least not polyethylene." ”

Yang Yi carefully put the plastic bottle on the shovel and stretched it into the furnace, and at a high temperature of more than 1,000 degrees, the plastic bottle was deformed very quickly and burned.

Quickly took out the shovel, Yang Yi wanted to blow out the burning plastic bottle, but the fire was too big to blow out with his mouth, so Yang Yiyou had to put the shovel into the furnace until the plastic bottle stuck to the shovel burned out.

Polyethylene melts at temperatures between 160 and 80 degrees, and it's not easy to melt the bottle instead of burning.

The shovel quickly burned red in the hearth, Yang Yi put the shovel on the ground, and waited for the color of the shovel to change from bright red to dark red, and then back to black, Yang Yi put the plastic bottle directly on the shovel.

The temperature of the shovel was about 400 degrees, and the plastic bottle soon began to melt when it was placed, but it also quickly began to emit green smoke, and then it burned again.

Blowing out the flames with his mouth, but the plastic bottle soon stopped melting, Yang Yi shook his head and said, "No, you still have to burn." ”

Chris was watching from the sidelines, he just did his job.

Yang Yi put the plastic bottle on the shovel again and then put it in the furnace to burn, but this time he didn't wait for the plastic bottle to burn, he put the shovel into the furnace and then quickly took it out, repeating the same action all the time.

Soon, the plastic bottle turned into a puddle of melted liquid, emitting green smoke and emitting an unpleasant smell.

Looking at the current form of the plastic bottle, Yang Yi nodded with satisfaction, and then put the shovel into the furnace again, letting the plastic liquid burn out.

Chris couldn't help but say, "Why is it burning again?" ”

Yang Yi shrugged his shoulders and said: "It's just a test, it's not very reliable to use only plastic, because it can't be made too coarse, it's not easy to pierce it if it's too coarse, it's too fine if it's too soft, it will bend, and if it's too brittle, it may break, and I need plastic that has enough strength and hardness but not too brittle, so I need a little additive." ”

Picking up the wooden stick that had been prepared a long time ago, Yang Yi smiled: "This is it." ”

"Stick, what can this do?"

Yang Yi put the wooden stick into the hearth, and the stick quickly burned, and then Yang Yi pulled the stick out of the hearth again.

After waving a few times in the air and extinguishing the burning stick, Yang Yi said lightly: "It's not a stick, it's charcoal, I don't know what will happen if you add charcoal to plastic, but according to the characteristics of polyethylene, even if it is melted once, it is still too soft, so after adding impurities, it may be able to harden." ”

After burning all the sticks and waiting for them to be extinguished and cooled, Yang Yi began to break the thin sticks, and then crushed the small charcoal pieces on the ground little by little.

Yang Yi only got a small handful of charcoal powder, but it should be enough.

In fact, Yang Yi doesn't know if adding toner to the melted plastic can increase the hardness, but logically speaking, adding other impurities to the plastic will definitely change the form, except for the toner, other things can be used, but Yang Yi can only find charcoal powder, which is an easily obtainable powdery object, and if there is no toner, then even if a stone is crushed into powder, it can be tried.

Anyway, it's all experiments, and Yang Yi has neither done it himself nor seen others do it, so just try it all and know it.

Ready to prepare the toner, Yang Yi once again turned several plastic bottles into a semi-liquid and semi-solid state, with experience, this time it was much smoother.

Poured the smoking, pungent smell liquid into the paper tube containing potato chips, and then Yang Yi quickly threw the toner in, and then used a wooden pipe to stir it hard, and when the plastic liquid could not be stirred, he pulled out the wooden stick and waited for the plastic to cool.

Until it was quite hot to touch the plastic liquid, but it could also be touched with his hands, Yang Yi quickly destroyed the paper tube, and then began to ** it with his gloved hands.

Soon, a black plastic stick about 30 centimeters long was formed, and then a tip could be easily pinched out by hand.

The plastic stick is as thick as a thumb, and the resistance is too great when it is thick, it is not easy to go deep when stabbing people, and it will break if it is too thin, or it is too soft and bent when stabbed, but Yang Yi doesn't want to just need a stick, he wants a triangular pyramid.

The triangle is the most stable shape, and as a weapon that can only be stabbed, the triangular pyramid is undoubtedly the most stable shape, and it is too simple to make three edges with your hands on a stick that can be kneaded at will.

While the plastic was not yet hard, Yang Yi tried to make the tip of the triangular pyramid as smooth as possible, because it was a spike made of plastic, Yang Yi did not dare to make the triangular pyramid too sharp, but the shape he chose was to ensure the strength as much as possible, and also have the greatest strength.

The triangular pyramid finally cooled down completely, and Yang Yi casually blasted to the ground beside him, he would rather do it again than use a weapon that didn't know the performance at all.

The plastic triangular pyramid is not broken, nor is it bent, but the tip of the cone is deformed by the top, but with the same force, it can definitely pierce a person's stomach.

Yang Yi was satisfied, very, very satisfied, and now, he had a weapon that was lethal enough, and longer than the self-made weapons of most prison inmates.

But Yang Yi was not satisfied, an inch long is an inch strong, so he decided to make a longer and easier weapon, and he already had a plan for what to do.

For Yang Yi, who has already been beaten with a baton twice, he feels that it is a good choice to make a baton, and it is a baton that is easy to hide and has enough lethality.
