This is the first time Jingyuan has been active at night. To be honest, facing those rotting zombies alone at night in such a ghost town is quite psychologically stressful.

Darkness is one of the most primitive fears deep in the human heart.

He found that a small number of zombies were attracted by the beam of a flashlight. The difference lies in the eyes of the zombies. Zombies with less decayed eyes seemed to be able to distinguish the beam in the dark.

In order to avoid unnecessary complications, he could only move forward in the dark, completely abandoning his blurry vision and relying only on his "snake" senses.

He took off his shoes and stepped on the ground wearing only his socks so that he could feel the vibrations nearby more clearly.

This was not a very good choice, because there were many sharp stone fragments on the ground nearby, and his socks were scratched within a few steps.

Fortunately, after evolving, his defense has also been improved. His skin is more tough than before and will not be so easily pierced by stone fragments.

I went out to find an abandoned truck and remove the leaf springs from its bearings.

There were abandoned vehicles everywhere in the city, and trucks were not difficult to find. Soon he found a large overturned truck on a nearby asphalt roadside.

It was a tank truck, and the cargo box carried a huge metal can. Jingyuan's purpose was just the leaf spring, so he didn't pay attention to anything else and went directly to the base of the truck.

I turned on the small flashlight and looked around. I found those layers of curved steel slats where the tires connected to the big frame, just above the tires.

It is about one meter long and looks very thick. After counting, there are a total of thirteen steel plates from long to short forming a triangle-like shape.

A cage-like lock is fixed on the bearing. To remove it, it is best to unscrew the thick bolt on the lock first.

Jingyuan did not have a wrench suitable for the size of such a thick bolt, so he tried it directly. It was very strong and could not be tightened at all.

After all, it is a shock-absorbing component for trucks and is very strong.

He thought there might be relevant tools in the car, so he used an eggplant knife to smash the front glass of the car.

There was a long-dead corpse inside, that of the truck driver. The driver's forehead deflated under the violent impact, and the round head turned into a toilet-shaped dent, which looked weird and terrifying.

Jingyuan endured the nausea in his heart, grabbed the corpse's neck, pulled it out, and threw it out. The left hand of the corpse was torn off and left on the twisted driver's seat.

Jingyuan took a deep breath, calmed down, and got into the driver's seat. After some searching, he found a large tool box.

That's it. He hurriedly got out. The smell inside was indeed a bit unpleasant. It was clogged and turbid. The stench produced by the corpse's decomposition process had been gathering in this small space. If he hadn't blocked his sense of smell in a hurry,

, it’s really disgusting.

He smelled it a little, and even his body was covered in the smell.

Fortunately, he found a wrench that was large enough, and there was a half-used bottle of lubricant in the big tool box.

He took a wrench, climbed onto the overturned truck box, poured lubricant on it, then unscrewed several bolts on the wheels, removed one tire, then unscrewed the bolts on the leaf spring, and removed the retaining bracket.

.

The twisting was very strenuous, and after a while, he felt exhausted because he felt hungry again.

However, he finally removed the leaf spring.

There are a total of thirteen arc-shaped elastic steel plates. They are not glued together, but overlapped together like tiles.

Four of them have been broken, and it is inferred that they were broken when the truck rolled over and slid.

Most of the rest were still in good condition, especially the longest one, which was about 120 to 130 centimeters. He overlapped two or three of them, placed them on the ground, and stepped on them, but he couldn't even bend them.

It wasn't until he moved and applied more downward pressure that he felt the toughness and elasticity.

A very good material that can definitely provide strong elastic potential energy for bows and arrows.

He couldn't carry all the leaf springs away because they were too heavy. According to his estimation, the remaining nine together were heavier than the diesel generator he found at the high-speed rail station, which means the total weight exceeded 100 kilograms.

There is no need for nine steel plates, because they are stacked together and reach Jingyuan's knees, which would be too thick to make a crossbow arm.

He only took the four longest and heaviest ones, carried these heavy industrial products on his back, and hurried back to Shiliyangguang.

After returning, he added some food and water, and then cooked these tough bones.

He tried to tie the leaf springs tightly with straw ropes, but the quality of the straw ropes was not enough. When he applied force, the ropes would break, so he used snake tendons instead.

After it was tied, it was placed on the ground, and with a dull sound, the prototype of a heavy crossbow arm was formed.

With just his arms, he couldn't bend this thing at all. He had to use both hands and feet together to clearly feel the heavy and solid power.

Jingyuan recalled the shape of the crossbow and drew the design on paper.

A long object is needed to stand up the crossbow arm in order to adjust the shooting direction and place the crossbow arrows.

Then there is the issue of stringing. The strength of the snake tendon is sufficient, but you have to consider how to fix the snake tendon into a string.

According to his intuition, if this crossbow is built, its range will be at least 300 meters, which is enough for him to set fire to the mutated sparrow's nest from a safe distance.

This will also become a huge killing weapon, such as rifles and pistols. When facing certain large mutant monsters, they will inevitably show fatigue.

Take Brother Snake for example, the mutated python is 12 meters long, and he must accurately hit the snake's head with bullets to cause effective damage, which requires very high accuracy on the head.

But after building this heavy crossbow, it was different. He could use thick steel bars as arrowheads. When he encountered similar mutant creatures, he didn't need to be so careful and wait for the opportunity. He could directly use steel bars to nail them to the ground.

Let's call it the Leaf Spring Heavy Crossbow. Before it was finished, he had already thought of a name for this new weapon.

He had to take it back to the southern suburbs for processing, otherwise the weight would be too heavy for him to move alone after it was built.

However, it can be fixed on an agricultural tricycle to create a mobile fort.

It's a pity that Xiaobai is a dog who can't drive a three-wheeler. If he had a partner who could drive, he would be excited just thinking about it. He could fire the gun while driving! The three-wheeler can be used as an earthen tank!

Isn’t that what ancient chariots were like?

He became more and more excited. He picked up the snake tendon and measured it on the leaf spring crossbow arm. However, after thinking about it, it seemed that he could not fix the snake tendon on these steel plates well by himself, because their surface had no

The groove also has no bolt holes and is a complete flat surface.

He didn't dare to use a hammer to dig a hole. It didn't matter whether he could dig it or not. This kind of brute force method could easily break the leaf spring, which required an electric drill.

Or, he thought of Xiao Yun'er. With the speed and strength of those vines, it wouldn't be a problem to drill a few holes in the steel plate.

However, it was clearly stated that I would not meet her until the day after, and she had not found a new dress yet.

Jingyuan thought for a long time and felt that it would be most reliable to ask Xiao Yuner for help.

But I don't feel good about going to see her empty-handed and asking her for help. I won't be able to get the new dress tomorrow, and it will take a whole day just to wash the clothes and dry them. I can't go to her with dirty clothes.

What should he do? He thought for a while and went to 902 to get all the jewelry back, clean it, and use these jewelry as reward.

After making this decision, he used the remaining water to carefully wash away the stench mixed with engine oil, and then lay down on the sofa to sleep.
