Just like when conducting nuclear reaction experiments on Earth, nuclear fission and nuclear fusion also use hydrogen and helium for nuclear reactions, but the energy produced is different.

The energy produced by nuclear fission reaction is not at all comparable to nuclear fusion reaction, and the two are not comparable at all.

For the study of the dark spirit crystal, it can only be regarded as keeping up with the steps of this world, but how can he be satisfied with the current state.

Now that we have stood on the basis of our predecessors, the next step is to break through the existing research progress and reach an unknown field.

With the continuous deepening of research, Zhou Yun has gained a lot, however, these gains can only be regarded as some small gains, after all, he has only studied for a day, even if he has mastered some knowledge about the dark spirit crystal, it is impossible to have a major discovery in such a short period of time.

Time passed slowly, the sky slowly darkened, in this world, the night of the sky took on a dark red, especially in the evening, the sky was darker, like a beast that chose people and loved it, quietly waiting for its prey.

It's already evening, and I've been busy for a long time today, and I'm a little tired, so I'm ready to take a good rest and continue my research tomorrow.

After a night without words, after getting up, stretched a lazy waist, Zhou Yun walked to the window, looked at the sky outside the window after the light, a little stupid, the morning sky, and the evening are completely two extremes, the evening sky is deep in color, no beauty, the morning sky is completely different, the color is beautiful, like a beautiful painting.

A new day has begun, and Zhou Yun is also going to start a new research, yesterday, he has a great understanding of the dark spirit crystal, and the research progress has also advanced.

But he didn't expect that at this time, an uninvited guest came, Yueyu, the woman of the Moon Butterfly Clan, he hadn't seen each other for more than a day, but he didn't expect the other party to appear in his laboratory.

Now it seems that his next arrangements have to be changed, the plan can't catch up with the changes, he doesn't want to expose his research on the dark spirit crystal in front of Lingyue, the other party is a person from this world after all, and he hasn't let down his guard yet.

Zhou Yun didn't understand why the other party came here, but now there was no choice but to let go of what he was doing.

"Lingyue, what's the matter with you, why did you come to my lab?"

Hearing Zhou Yun's words, Lingyue was a little helpless, can't he come if there is nothing to do, Zhou Yun doesn't know what Lingyue thinks, he only has one thought now, that is, he hopes that Lingyue will leave the laboratory as soon as possible, he doesn't want to waste time.

As a person who is obsessed with scientific research, female creatures are important for research, which is the only thought in Zhou Yun's heart.

"Tomorrow, the high-level of our Moon Butterfly Clan will hold a conference, in order to celebrate the victory of the previous war, and also to alert the residents of the Floating City, just now, the high-level of the clan found me and wanted me to invite you to participate in this conference."

At this time, Zhou Yun pondered for a while, but he couldn't make up his mind, he didn't like that kind of noisy scene, if it was someone else from the Moon Butterfly Clan who came to invite him this time, he wouldn't accept the invitation at all.

But this time it was Yueyu who came, which made him fall into contemplation, and in the end, he decided to accept this invitation, although there was a factor of Yueyu, but the most important thing was that he didn't want to get too stiff with the Yuedie Clan, and he still wanted to learn the knowledge of the Yuedie Clan in the future.

Every civilization has merits, and he has never doubted this, even if he looks down on the deformed civilization of this world, he will not deny the merits of this world civilization.

Taking the essence and removing the bad cypress is the most correct attitude of a scientific researcher.

Lingyue saw Zhou Yun enter into contemplation, and did not bother, she knew why the high-level of the Moon Butterfly Clan would look for her, although she didn't want to come, but the Moon Butterfly Clan was her race after all, although she was reluctant, she still came to Zhou Yun's laboratory.

Hearing Zhou Yun's clear answer, Yueyu was relieved and was about to leave this place, she really didn't have the heart to stay, she knew in her heart that after today's incident, there would definitely be a gap between the two of them, and there was no way to do it.

For this situation, Zhou Yun did not keep the other party, although the incident just now was not from Yueyu's original intention, but since the other party did this for the sake of his own race, it also means that their friendship has become very dangerous.

However, Zhou Yun didn't feel sorry for this kind of thing, in this world, he could only be regarded as a passerby, and when he left this world, he wouldn't take the place away at all, because he didn't want Yueyu to become his weakness.

On the earth star, the reason why he is not worried about Millican's revenge is because he does not have any weakness, his parents are nowhere to be found, and he has no other relatives, as the saying goes, barefoot is not afraid of wearing shoes, Zhou Yun is the kind of barefoot.

After a while, Yueyu had already walked away, Zhou Yun returned to the experimental instrument, ready to continue the research, just now, when talking to Yueyu, an idea suddenly appeared in his mind, and it was this idea that would make him hurry back to the laboratory for verification.

Dark spirit crystals have appeared in this world for hundreds of years, but the application is very narrow, only for the research of weapons, it will appear more professional, no matter where it is, weapon research is always put in the first place, only with strong force, is fundamental.

Zhou Yun naturally understood this situation, but now his thoughts have changed, the energy crystal containing huge energy can be used as the energy source of the meteorite steel suit, and now he is a little helpless, now it is just an idea, and it has not been studied yet, and it cannot be realized at all.

As the energy source of the meteoric steel suit, it is impossible for the people of this world to think of it at all, because in this world, there is no meteoric steel suit at all.

Now that he has an idea, he naturally wants to realize this idea, the energy source of the meteorite steel suit is the Ark Reactor, in terms of performance, it is naturally inferior to the Dark Spirit Crystal, but he still doesn't know how to obtain stable energy from the Dark Spirit Crystal.

A few hours later, Zhou Yun looked at the research data in front of him, his face showed happiness, he finally found a way to develop this dark spirit crystal, at present, it seems that this dark energy crystal can replace the Ark Reactor, after coming to this world, he has been worried that the energy consumption of the meteorite steel suit is too fast and cannot be replenished, in that way, he will lose this big killing weapon, but now, he doesn't need to worry.

As long as he has a dark spirit crystal, he can have a steady stream of energy.
