Xiao Yi walked into the hardware supermarket and bought a cutting machine, an electric welding machine, an electric drill, a percussion drill, and a nail gun. There are also quite a few screws. In the end, he bought some thick steel plate material. After these things are processed, the doors and windows can be reinforced, and his main consideration is to weld his own doors into steel plates. In this way, collisions can be avoided and the door can be quickly deformed.

Xiao Yi finished shopping and was about to leave, when suddenly he saw several special pieces of metal on the ground of this hardware supermarket. It was a few inconspicuous pieces of black metal, but it was these inconspicuous pieces of black metal that caught Xiao Yi's attention.

"What kind of metal is this, why haven't I seen it?"

"That's the special S steel newly developed by the Telling Steel Mill."

"How do you have this here?"

"This thing was taken out by my brother in the factory and given to me to play, but this is a good thing, the S-grade steel produced by Terlin Farm, this is a special steel, I heard that it was researched to make metal clothing!"

"Boss, do you sell this piece of steel?"

"What do you want him to do? It's useless, this kind of steel is not something that ordinary 3D printers can smelt. I've tried it since I brought it, and now I can only use it as a collection. ”

"Boss, you can sell him to me. I'll go back and make a collection. ”

The sales boss looked at Xiao Yi, who had a serious face, and immediately smiled.

"You can take both of them, but this thing is not cheap, so you can give 2,000 yuan."

Hearing this, Xiao Yi immediately happily agreed, and directly picked up the two pieces of black metal.

This thing is not heavy, pick it up, Xiao Yi paid the bill through the citizen terminal and left.

He had seen this kind of steel in his previous life, this kind of steel could not be cut with normal cutting tools, but he could use his ability to turn it into molten steel, and the devil in his previous life could kill humans wearing armor of this material by releasing a lightning ball, and Xiao Yi remembered that after the person was attacked, he was directly vaporized, and even this steel coat was melted into molten iron, but it did not hinder the reality of this material's super defense, so this thing is still very valuable.

When I returned home, I said hello to Lu Xuexin and immediately got busy.

"Xuexin, you go to the bedroom first, it may be noisy outside for a while, and you are buying some food at the online store through the computer."

"I see."

With the arrangement Xiao Yi also officially began to get busy, first cut the steel, welded, began to install, cut the steel plate, reinforced on the original metal door, suddenly the metal door has a sense of heaviness, for safety reasons, Xiao Yi also added an artificial lock, is a heavy guy, so as to avoid the door being knocked open, and then he began to reinforce the door frame. Punching holes in the wall, he wanted to make the door frame fixing points more, he added a steel frame, and at the same time pierced the door frame and fixed it with screws, and immediately felt quite satisfied. In the end, the screws were dried up with electric welding. Looking at his work, he nodded with satisfaction.

Xiao Yi stood in front of the unrecognizable iron gate that had been transformed by himself at this moment, he was extremely proud in his heart, although he had never done it, but this level was not bad.

Everything that can be changed has been changed. Even the small door at Maoyan, he also replaced the steel plate, Xiao Yi thought about it, through here, assassinate the zombies outside, and avoid the zombies from entering the door, which is also very good.

And the floor, Xiao Yi is also wrapped in metal, this is Xiao Yi in order to awaken the electric ability, can use the conductive properties of the steel plate to kill the zombies outside.

Everything was ready, at this moment, the sound of propellers suddenly came from outside, Xiao Yi knew that this was an unmanned delivery plane, Xiao Yi was not pretentious, and came directly to the window, and saw that there was a huge package in front of the window that had been placed on the balcony.

Then the sound of the propeller became farther and farther away, Xiao Yi took the package into the house, opened it and took a look, and was suddenly a little speechless, they were all things commonly used by some girls, and after a while, the sound of propellers flew again.

This time, there are 5 boxes of instant noodles and 5 boxes of ham, which is enough to eat for a few weeks.

It's 18 o'clock in the afternoon. Xiao Yi saw that there was no other goods delivered, and looked at the bedroom door and saw that there was no movement.

Xiao Yi opened the bedroom door and asked Lu Xuexin inside.

"Anything else?"

"That's all."

"Yes! Then I'll strengthen the balcony! ”

Xiao Yi began to strengthen the balcony again. These key exits must be strengthened, and in the future world, in addition to zombies, there will be mutant beasts, such as mutant bats, mutant rats and so on.

These are quite dangerous.

When everything is ready, 23:25.

Xiao Yi and Lu Xuexin were already armed to the teeth, wearing thick clothes and wearing gas masks.

There was a gas leak in the neighborhood that injured a lot of people, and then the government issued this gas mask to everyone, so let's just use it.

The fire axe, and a steel cone with a sharpened head, this thing was welded to the front end of an iron pipe at the moment, and Xiao Yi felt that this thing could be used as a spear.

The two walked to the window and looked at the night outside, today it was exceptionally quiet outside, and at the same time it was exceptionally cold, the weather in May should not have been like this. But today it's a little weird.

Time: 23:50

At this moment, the sky suddenly changed.

"Xiao Yi, what's that?" Xiao Yi looked in the direction of Lu Xuexin's finger.

At this moment, a bright spot suddenly appeared in the sky, it should be a military aircraft.

"What the hell is going on, in the next moment, the sky suddenly rumbled, and a lightning bolt appeared out of thin air.

Xiao Yi only felt a pain in his head, and he was about to faint, but at this moment, Lu Xuexin had already fainted on the ground. Xiao Yi covered his forehead, what the hell is this.

At this moment, Xiao Yi's brain clearly felt abnormality, and just after the loud bang just now, there was actually an extra thing in the middle of his brain out of thin air.

The next moment, Xiao Yi found that his body was getting hot, Xiao Yi didn't know what the situation was, but he still hurriedly walked to the direction of the door of the room, trying to stay away from Lu Xuexin, he was afraid that the abnormality of his body would cause harm to Lu Xuexin.

With a loud bang, the sky suddenly and inexplicably began to rain black. The rain was dark, like ink.

The fall of the black rain, the sound of car collisions outside, and the strange roar, suddenly there was a commotion outside, accompanied by the sudden sound of air defense sirens, which made the whole city explode.

The rainy night that had been quiet was broken all at once.

At this moment, Xiao Yi's body is exuding a frequency of lightning, at the beginning, a flash, dotted with stars, and gradually the arc of the body flashes faster and faster, Xiao Yi knows that his ability is about to awaken, and he must not faint this time, at this moment he clenched his fists, gritted his teeth, and felt the numbness in his body, he felt that his heart must have been cooked under such a strong current stimulation, but his feeling told himself that this was very cool!
