Looking at the fat man Cao who rushed out like a demon, Zhang Wenjing laughed: "He is actually a technical nerd." ”

When Li Guan came back from rebirth, he was a little out of touch with society, and wondered: "What is a technology nerd?" ”

Zhang Wenjing said: "It is an otaku with strong hands-on ability, very rich professional knowledge, and likes to create some strange and amazing products." ”

Li Guan nodded thoughtfully, and asked again, "Then what are you proficient in?" ”

Zhang Wenjing asked rhetorically: "What do you think?" ”

"Firearms?"

Zhang Wenjing laughed and said with an extremely serious expression: "If I tell you that I can even make cannonballs, do you believe it or not?" ”

Li Guan was silent for a while and said, "Let's eat." ”

“……”

'Boom'

At night, the bright light kept flashing, and Cao Fatzi was wearing sunglasses, holding an electroslag pressure welder in his hand, constantly tapping the steel.

The welding of steel bars can not be welded by argon arc welding, but can only be welded by more powerful electroslag pressure. And the repair shop just has this kind of large-scale electroslag pressure welding, too, after all, it is a repair shop for repairing trucks, and there are few places where common argon arc welding can be used after all, and the repairs are all steel monsters.

However, electroslag pressure welding has very large requirements for power supply, and now in the end of the world, how can there be power supply?

Not only is there no electricity, but there is not even a diesel generator. However, this is not difficult for Cao Fatzi, this guy can actually make his own electricity.

A few hours ago.

Cao Fatzi found a lot of steel scrap in the repair shop, as well as obsolete heavy truck circuit facilities. Cutting with a cutting machine, punching holes and screws, using his professional knowledge, he actually built a hand, electricity, and dual-kinetic energy generator. With the assistance of Li Guan and Zhang Wenjing, it only took him half a day to build the generator.

An electric motor for ignition was removed from another trailer, and the manual power generation was directly discarded and electricity was used. And this battery also directly helped Cao Fatzi to use the cutting machine and a series of equipment in the early days, so that he did not have to build it by hand.

The electric motor is used as the heart of the generator, and the electric motor of the heavy-duty truck is used as the power. As soon as the battery is connected to the electric motor, the generator is complete.

While installing the generator, Cao Fatzi said: "This is actually the conversion process of force, using the direct current in the battery as kinetic energy, acting on the generator, and converting it into alternating current." ”

Li Guan and Zhang Wenjing looked dazed, and they couldn't understand.

Cao Fatzi wound the copper wire around the self-made generator rod, and said to himself: "Now the star connection method is adopted, the rod rotates at high speed to generate a rotating magnetic field, and the kinetic energy propagates to the claw pole to produce the beak pole, and the magnetic track is formed through the current magnetic field winding......"

Li Guan and Zhang Wenjing listened to the book of heaven, but they opened their mouths wide in surprise and looked at Cao Fatzi who was talking to himself. There was only one feeling in my heart - I didn't know how to feel it.

Cao Fatzi, a gangster, is too good, how can his scientific knowledge be so powerful? With such a powerful skill, it is really blind to go to the Golden Triangle to participate in the gang.

At this moment, Cao Fatzi was simply charming, and his disfigured face seemed to exude brilliance. Wiping the sweat from his fat body, he continued to mumble to himself while working. It's like he can't do a job if he doesn't talk to himself, it's a habit.

"The two conductive slip rings are fed with direct current through the carbon brush, and the current in the magnetic field shaft appears, generating an axial magnetic field, that is, the rotating rod rotates synchronously with the magnetic field...... The kinetic magnetic field rotates and enters the star stator windings, generating a three-phase alternating current. ”

The more the fat man speaks, the more unfathomable it feels, and the movements under his hands are not slow at all.

"When the ratio of the output of the stator coil to the speed of the generator increases, the regulator adjusts the amount of the energizing current of the rotor coil, so I can control the output voltage. Then this last copper wire is connected to the electroslag pressure welder, which outputs the arc and electroslag, melts the steel and produces a fusion ......"

After wiping the sweat again, Cao Fatzi drank a sip of water and stood up, clapping his hands: "It's done." ”

Li Guan and Zhang Wenjing were stunned to see that the shell was assembled and nailed up with wooden boards, and the internal equipment was extremely simple, and they looked like they didn't feel safe, and they were speechless for a while.

Cao Fatzi didn't have the heart to chat, so he plunged into the work again, initially tried to use electroslag pressure welding, and couldn't help but breathe a sigh of relief when he saw that the arc had been generated: "Fortunately, the welding machine is good, or you have to build a welding machine." ”

Li Guan's eyes widened, listening to this meaning, Cao Fatzi even built an electric welding machine? Do you want to be so rebellious, what is the story of Cao Fatzi before he became a gangster? He's even better than a scientist. It's too hands-on.

'Poof'

With a soft sound, the generator caught fire, and Li Guan and Zhang Wenjing hurriedly dodged away, for fear that the arc would shoot out.

Cao Fatzi was not in a hurry, wearing sunglasses and constantly welding and modifying the muck truck, and said without looking back: "Zhang Wenjing, please use sand to extinguish the fire, otherwise it will burn apart later." ”

Then he sighed again: "Alas, the structure and shell of the wooden nails are really unreliable." If only I had enough time, I used steel bars as a frame. ”

Zhang Wenjing found the sand and threw herself on the generator in fear. The fire was extinguished, but her heart was boiling.

Cao Fatzi, this simple you can't even tell that it's a generator, it's quite reliable?

'Boom'

Arcs and electroslag constantly weave between the steel, quickly melting the steel and then being welded together.

Zhang Wenjing and Li Guan saw that Cao Fatzi was just a simple weld now, and he no longer built any machines, so they were quite bored, so they went to sleep.

All night, the sound of welding and the sound of collision just now, the noise of the cutting machine did not stop. Cao Fatzi's dedication to it is like a "martial idiot", too focused.

Early the next morning.

Li Guan and Zhang Wenjing both got up, and as soon as they went out, their eyes widened in shock. In Cao Fatzi's professional field, the two of them were only surprised except surprised.

But I saw that there was a ferocious steel monster parked in the courtyard.

It's a muck truck, but you can't tell it's a muck truck at all.

In front of the muck truck is a shovel like a snow plow, which is wide and very sharp. Like the tusks of a wild boar, they stick out of their heads and are two meters long.

And above this huge shovel, there is a row of steel spikes. Each steel spike was polished into three edges, each of which was serrated and nearly two meters long. Just the front of the car, there is almost a feeling that the gods block and kill the gods, and the Buddha blocks and kills the Buddha.

Looking at the left and right sides of the muck truck, the uneven and messy furnishings are all steel knives, each steel knife is cut out of pure steel, and then polished into a sharp jagged shape, piercing out the body about half a meter.

Just by looking at the steel knife groups on both sides, it is not difficult to imagine what it is like to drive through the zombie group, and everywhere you go, you can cut everything in half.

The four wheels of the front single and rear double are densely covered with steel thorns. It's not hard to imagine that as soon as the car moves and the tires spin, these steel spikes spin with them, creating a terrifying twisting force that tears everything apart.

The compartment behind the muck truck, as well as on the butt of the car, were all uneven steel spikes one or two meters long, which made it difficult for anything to approach.

Above the muck wagon, a push-pull closure cover extends out like fang-like steel spikes in all directions. Because the last time the forklift was smashed by the birdman, this time Cao Fatzi was still on the roof of the muck truck, not only installed steel spines, but also installed an eaves type anti-collision layer that is narrow at the top and wide at the bottom.

As long as a boulder falls, it will not hurt the muck truck, but will slide down directly along the narrow and wide anti-collision layer.

There are also a lot of articles on the front of the car, and on several glass windows, there are steel guardrails like anti-theft windows, as long as they are not opened from the inside, from the outside, the gods can't enter.

This can already be called the first car of the apocalypse.
