Although metal smelting is very difficult for humans on the mainland, it is not a problem for Shi Leiyin. Slimes already have the ability to refine metals, and different slimes will have the ability to disassemble and store different metals. It's just that this ability is very random, and even the same slime will change after splitting, resulting in humans discovering this ability, but they can't use it to help smelt metals.

This kind of problem does not exist for Shi Leiyin, who has a large number of different slime abilities. The Devouring Fusion ability allows Shi Leiyin to disassemble any natural alloy that enters his body at will, record the proportion of metals it is made of, and then reproduce the alloy in his body using direct synthesis. If necessary, Thunder can even use this ability to synthesize Mithril or Adamantite.

Of course, even if it is an artificial alloy, as long as it takes enough time, Shi Leiyin can also be analyzed, but for those special metals Shi Leiyin does not have enough ability to make them. Fortunately, because the body of this institution is to adapt to the new style created on this planet, the metals used are also alloys synthesized from metals that are not very rare on the mainland, which allows Shi Leiyin to obtain the metal raw materials he needs by dismantling mixed metal ores and those high-level equipment.

The mixed metal ore is not large, and Shi Leiyin simply took a moment to mine all the ore. Then he used some of it to make a huge chest on the back of the body of the machine, and put the rest of the ore in it along with those high-level weapons, ready to move and slowly refine it to the desired state.

Because of the need to refine, Shi Leiyin slowed down his movement. It also alleviates the situation that after adding a back box, the volume increases, and it is easier to attract those aggressive plants to attack.

While refining the ore, Shi Leiyin also shifted the center of the analytic body's body to the nuclear power system. The simple knowledge of nuclear energy in his mind knew that this energy system contained the technology he needed to make an external electromagnetic cannon.

Nuclear energy is a very powerful energy, and Shi Leiyin does not expect to be able to replicate the fusion power furnace at the core before completing a full analysis. What he needed was a cooling system as an auxiliary and a voltage system that regulated the energy output.

The basic principle of the electromagnetic cannon is not complicated, what affects its power is the initial velocity that the electromagnetic coil can achieve when pushing the projectile. When he is in Shi Leiyin's body, he can control his body to generate a large amount of current and extremely high voltage, which makes the cannonballs fired have quite good lethality.

In the case of in vitro, it is necessary to use additional capacitors that store current and a booster device that is responsible for increasing the voltage. Shi Leiyin did not have the knowledge of these devices, so he could only use the devices used by the energy system in the body of the mechanism to make a certain degree of modification attempt, and then make a device that was sufficient to provide an external electromagnetic cannon launch.

Similarly, the huge heat energy generated by the electromagnetic gun has an impact on the material of the gun body, and also has high requirements for the cooling system. When in the body, Shi Leiyin naturally doesn't need to worry about this problem, not only can the body withstand a high enough temperature, but the ice attribute energy can also allow him to easily offset those high heats, and the worst can be solved by rapid regeneration.

The material of the external barrel, Shi Leiyin has chosen the normal temperature superconducting material in the body of the mechanism, and the superconducting material is one of the best materials for the electromagnetic gun. However, the relatively low melting point of superconducting materials is a serious problem, which means that the high temperature after the launch of the electromagnetic gun is very likely to melt the superconducting coil. This is also the purpose of the cooling system of nuclear energy, the high temperature of the fusion reaction is much higher than the temperature produced by the electromagnetic gun, so the function of the cooling system should also be enough to quickly cool the high temperature brought by the electromagnetic gun when it is fired.

Of course, all these problems will have to be confirmed after Shi Leiyin officially makes the electromagnetic cannon.

After spending nearly three hours, Shi Leiyin finally finished refining the ore and dismantling the equipment before nightfall.

The night of the Stone Forest Secret Realm came much earlier than outside, and due to the relationship between the tall stone pillars and the plant network at the top, the ground of the Stone Forest Secret Realm had already entered darkness when it entered dusk. Those plants that were able to move also reduced their activity, and stopped harassing Shi Leiyin.

The secret outer circle of the stone forest at night is a completely different scene from the daytime. Dots of light emerge from the reticulated plants at the top, shining like a starry sky above the Stone Forest Secret Realm.

However, in Shi Leiyin's field of vision, those nocturnal flying insects attracted by the 'starlight' were stuck to those nets, and then quickly decomposed and absorbed. Apparently, this is the nocturnal predation of these reticulated plants.

At night when the plants stop moving, nocturnal insects begin to appear. Beetles of all sizes crawl out of underground burrows where they hide and eat their favorite plants. Spiders, scorpions and other predatory insects sneak up from stone pillars and plants to prey on their favorite food.

Without the threat of carnivorous plants, the secret outer circle of the stone forest at night is actually more lively than during the day.

Shi Leiyin turned off the light irradiation function on the body of the mechanism, and he did not need these functions that would attract phototaxis insects with night vision.

However, Shi Leiyin didn't mind turning the bug that accidentally knocked him down and tried to bite him into his own nutrients. There are many insects that have not been included in Shi Leiyin. Because these insects are just ordinary insects and not monsters, even if Shi Leiyin has encountered them before, he has no idea of absorbing their genes. However, after absorbing a few bugs that tried to attack the soles of his feet, Shi Leiyin realized that he had almost missed out on a large gene pool.

Unlike mammals, insects have more powerful and perfect structures, and in addition to being affected by oxygen levels due to their natural defects, they are far more survivable than mammals and even reptiles, and perhaps only top-tier creatures such as ancient wurms can win.

Shi Leiyin disdains the genetic structure of ordinary creatures because these ordinary creatures lack the great strength or special abilities of monsters.

But insects can't be treated equally, and after absorbing several bugs, Shi Leiyin was stunned to find that the body structure of these ordinary bugs was even more reasonable and powerful than the Lemut spider, which belonged to the insect family of demonic beasts. This completely subverted the fixed notion in Shi Leiyin's consciousness that monsters were more powerful than ordinary creatures.

After taking the initiative to absorb more kinds of bugs, Shi Leiyin was even more sure of one thing - these ordinary bugs, at least these ordinary bugs in the Stone Forest Secret Realm, evolved more perfectly than most of the bug-based demonic beasts on the continent.
