I can upgrade the shelter

Qin Lan and Mo Qingyan couldn’t quite grasp what Chen Xin meant by electromagnetic metallurgy, but since Chen Xin asked for their help, they naturally wouldn’t refuse and followed his instructions on the tasks he assigned them.

"Qingyan, these metal rods are already wrapped with copper wire, take them to Axin." Qin Lan handed several metal rods wrapped with copper wire to Mo Qingyan, instructing her to take them to Chen Xin.

Mo Qingyan took the iron rods passed by Qin Lan, nodded, and walked towards Chen Xin.

At this moment, Chen Xin was working on a rather peculiar-looking machine, with several metal rods wrapped with copper wire connected to a circular turntable, resembling an upside-down tripod stool that could rotate.

Mo Qingyan handed the metal rods she brought to Chen Xin, glanced at what he was making, and asked, "Axin, is there anything else you need help with? Is it really sufficient to just wrap copper wire around these few iron rods?"

"That’s enough, I can handle the other parts myself, and this machine itself isn’t complicated." Chen Xin smiled at Mo Qingyan, indicating that it was sufficient.

Using a mechanical arm, Chen Xin welded the metal rods brought by Mo Qingyan onto another turntable, then assembled the two turntables and another mechanical arm together.

Mo Qingyan watched as Chen Xin finished assembling the item, thinking it looked much like an egg beater, which made her somewhat curious about how it operated.

Even though Mo Qingyan voiced her curiosity to Chen Xin, she wasn’t expecting an answer, as she assumed she wouldn’t understand his explanation even if he provided one.

"This device uses these metal rods as electrodes to discharge onto the metal materials placed in the center, using the arc produced by the discharge to melt the metal materials." As Chen Xin assembled the machine, he spun the metal rods on the turntable, which looked like chicken claws, introducing the setup to Mo Qingyan: "As long as the current is strong enough and the arc’s temperature is high enough, anything can be melted."

"(⊙o⊙)..." Mo Qingyan indicated that she didn’t understand what Chen Xin was talking about.

Chen Xin wasn’t annoyed, simply smiled and said, "It’s okay if you don’t understand, just know that I can use this machine to remelt recycled scrap metal into new materials."

"Oh, so that’s how it works!" Mo Qingyan showed a face displaying "I totally understand now."

Chen Xin could tell that Mo Qingyan actually didn’t understand at all.

However, he didn’t mind, once the machine was assembled, he connected it to another Isotope Thermoelectric Battery he had removed from his vehicle, planning to use it for power supply.

Currently, one of the car’s three batteries was removed to power the rescue station, one was used here, and the car only had one battery left for power. Unless Chen Xin reinstalled the battery, the car wasn’t capable of driving for now.

This didn’t significantly affect Chen Xin, as he only had residential needs for his car now, not driving needs, so there was no immediate necessity to drive. Even if there was a need, temporarily making a battery or reinstalling the battery wouldn’t take much effort or delay anything.

Of course, the setup before them was fairly rudimentary; to make it functional, Chen Xin had to invest some survival points into it.

The investment of survival points transformed the machine, making it appear newly upgraded and more sci-fi, like a real deal. Simply put, it shifted from a green style to a NEC aesthetic.

The overall design of the machine didn’t change much, as it still featured a pillar connecting two circular turntables with metal rods protruding from them.

The bottom turntable resembled a large tray, surrounded by three vertical metal rods that looked like chicken claws, whereas the top slightly differed with the metal rods turning black, seeming more like a plug.

After upgrading, Chen Xin was quite satisfied with the machine, deciding to test its effectiveness.

Placing some scrap metal onto the bottom turntable, after signaling Mo Qingyan to step back, Chen Xin pressed the machine’s start button.

Upon power supply engagement, the three metal rods at the base began to rotate, and as the speed increased and the current intensified, the scrap metal on the tray surrounded by the metal rods gradually started vibrating and then levitated.

"Those three metal rods are actually electromagnets. Their rapid rotation forms a magnetic field, thus lifting those scrap metals." Chen Xin explained to Mo Qingyan and Qin Lan, who had arrived at some point, while observing that the metal rods’ speed was stable enough to keep the scrap metal levitating. Following this, he pressed the second button.

The plug at the machine’s top lowered slowly, its metal rods touching the floating scrap metal in the center, then began discharging.

Bright arcs were released from the electrodes at the metal rods’ ends, striking the suspended scrap metal, creating snapping sounds and intense sparks which made both Qin Lan and Mo Qingyan unable to resist shielding their eyes with their hands, while Chen Xin had already lowered the shading mask on his face shield.

As the arcs crackled, the scrap metal bound by the magnetic field started to melt gradually, and the sparks released from the electrodes grew increasingly intense, resembling welding operations.

Qin Lan’s Power Armor also had a shading mask, so she lowered it to clearly see the scrap metal in the machine transforming into a mass of orange-red liquid under the arc’s effect.

The melted liquid metal emitted massive heat, causing the surrounding snow to melt, generating copious steam which immediately sublimed into water vapor due to the high temperature.

Although they had melted into a mass of liquid, the liquid was still held by the magnetic field, suspended in the machine without falling.

"A-Lan, what’s happening exactly?" Mo Qingyan, whose Protective Suit helmet lacked a shading mask, could only shield her eyes with one hand while turning her head to inquire Qin Lan.

"I don’t know either; it seems like after Axin started the machine, many sparks appeared, causing the scrap metal to melt. Now it seems impurities are dripping off." Qin Lan adjusted the aiming scope on her helmet, switching visual modes to clearly see black impurities continuously surfacing on the molten metal surface and then falling to the tray below.

At this point, Chen Xin wasn’t keen on answering the doubts of Qin Lan and Mo Qingyan. With the machine’s operation, Chen Xin was fully engrossed in observing the machine, focusing on the orange-red liquid metal, continuously monitoring its condition with a scanning device on the mechanical arm.

"The machine is somewhat simplistic; it can’t control temperature, and impurity discharge is ineffective. It seems improvement is necessary." Watching the liquid metal gradually exhibit layering, Chen Xin felt somewhat dissatisfied.
