The problem of temperature, in fact, Song Zihang still has some methods, such as burning a real fire array in the iron-making furnace, the temperature of the real fire is definitely not comparable to ordinary fire, and it is absolutely possible to reach a high temperature of tens of thousands of degrees, so the problem of flame temperature can be solved, but if the real fire array is burned, then the burning energy is another problem.

Ordinary kerosene electricity can't support the operation of the real fire array at all, but this is not impossible to solve, Song Zihang thought about it and took out a piece of paper, and drew two very complex formation drawings on the paper, one is the real fire array, and the other is the energy conversion formation.

The energy conversion formation is a commonly used formation in the cultivation world, and the function of the formation is to convert all kinds of different energies into the energy you need.

The mountain protection array often needs to be used to resist enemies who are stronger than themselves, so it is necessary to gather the strength of everyone, but the strength of everyone is often different, and everyone's true qi is different, so it is necessary to summarize everyone's true qi and turn it into a kind of true qi, so as to urge the large array to change the situation of the battle!

This is the function of the energy conversion formation, it is the true qi of various attributes, which becomes an attribute true qi, so as to urge, Song Zihang combined the real fire array and the energy conversion formation with each other at this time, and then created the formation that Song Zihang needs, a formation that can convert coal, oil, and electricity into real fire!

After this formation is studied, the problem of flame temperature is solved, and the next problem to be solved is to find a refining equipment that can accommodate this temperature.

What kind of equipment can resist the continuous burning of real fire? Song Zihang thought about it, and felt that at the very least, the so-called magic weapon-level magic weapon in the world was needed to resist the burning of the true fire.

But if you want to refine a magic weapon, this is a very troublesome thing, Song Zihang is a little reluctant to get involved in this trouble, after thinking about it, Song Zihang suddenly thought of a metal material that can definitely withstand tens of thousands of degrees of high temperatures.

That is the fragments of the battleship that Wang Xingren shattered, and the battleship was blown up by Song Zihang himself one by one, so the hardness of the battleship Song Zihang has a number in his heart, in fact, the hardness of the battleship is very high, how high is it?

Song Zihang thought about it and gave a range, the hardness of the battleship should be comparable to that of ordinary immortal weapons, so the true fire is absolutely not damaged This kind of battleship, if you want to melt this kind of battleship, at least you need the samadhi true fire, or the sun true fire with a higher temperature than the samadhi real fire.

Only these two true fires can cause enough damage to the battleship!

Song Zihang thought, a teleportation, the whole person has flown out of the earth's atmosphere, appeared on the cosmic battlefield outside the atmosphere, on the battlefield, Song Zihang looked at the empty battlefield and was a little stunned, this earth country is too greedy, the fragments of the four destroyed warships are simply obscuring the sky, now it is so empty, you are too ruthless, there is nothing left!

However, when Song Zihang first thought of this, he felt that something was wrong, these countries on the earth are quite greedy, but in greed, they want to empty here, and they must also have this strength!

It's not that Song Zihang laughed at them, just their small spaceship, it is estimated that they will run two or three times, and the fragments of a battleship cannot all be taken away, so in addition to the possibility of being taken away by these people, there is only one possibility, that is, it was carried away by the universe itself.

The universe is like a calm lake, you see it is very calm, but if you put a leaf on it, it will soon be carried far away by the water.

And the fragments of those battleships should have been transported away by the universe, thinking of this, Song Zihang's divine consciousness radiated out, and the next moment Song Zihang really found that a large number of fragments were transported to a place very close to the sun, the temperature in that place was too high, and it was difficult for human spaceships to approach, which may also be the reason why human beings gave up.

Song Zihang thought, followed by a teleportation to the side of these fragments, and the next moment Song Zihang rummaged through the pile of fragments to see if there was anything that could be used.

At that time, during the war, Song Zihang's shot was a little heavy, which caused the engines of these warships, the command light brain and other parts to be damaged, and there was no valuable part left, which made Song Zihang feel a little pity, and said to himself that he was a little ruthless, and he knew that he would leave some fragments.

Song Zihang thought about it, and accidentally glanced at this pile of debris, followed by the whole person was stunned for an instant, looking in one direction, with some doubts in his eyes.

Brush!

Song Zihang flew over with a teleportation, and the next moment he reached out and picked up the thing that made his eyes light up in the ruins, it was a fist-sized stone, it was pitch black, but its surface contained a halo of energy visible to the naked eye.

Song Zihang knocked carefully, and found that this stone contained a very powerful energy, which was almost comparable to the mana of a heavenly immortal, Song Zihang looked at the stone and was slightly stunned, and then he remembered that in the pile of information that Anubi gave himself, it seemed that the origin of this stone was recorded.

Thinking of this, Song Zihang took out the information storage device that hid the entire Wang Xingren technology and looked at it, and soon he found a record about this stone.

Dark energy stone, a very valuable energy resource in the universe, can only be found on a very small number of white dwarf stars, white dwarfs, that is, the products of stellar energy depletion, slowly cooling for hundreds of millions of years, this kind of star has low luminosity, high density, high temperature and other characteristics, the overall color is white, the volume is relatively short compared to the star, so it is called a white dwarf.

The dark energy stone is produced on such a star, but it is difficult to mine, so it is very valuable, and in the three-star civilization of Wang Xingxing, such a power stone can only be used by the military, not for civilian use.

And it is precisely because the Wang Xingren discovered and used the energy of this dark energy stone that Wang Xing was able to complete the interstellar jump and support the warship to carry out a long time and space travel in space.

According to the records of the Wang Xingren, one dark energy stone is enough for a city of Wang Xingren to use for ten years without worrying about the problem of energy depletion, which shows how huge the energy of this dark energy stone is!!

Seeing this, Song Zihang couldn't help but nodded, this dark energy stone is definitely a good thing, now that I have this dark energy stone, then I have the energy to refine special metals, and I don't need to use conventional energy sources such as kerosene and electricity, so it seems that it will help me a lot.

Song Zihang thought about it and hurriedly radiated the Yuan Shen, and the next moment he began to carefully explore the entire space to see if there were any fish that had slipped through the net, and the dark energy stones that he hadn't found, this kind of good thing couldn't make him become cosmic garbage in the universe!
