It is a miracle that it has only taken hundreds of years for this world to develop from a primitive charcoal civilization to such an extent since the discovery of this bizarre crystal.

Now it seems that the edifice will fall, but, undeniably, it was once glorious, and this is an undeniable thing.

Thinking about the Earth Star Civilization, it took thousands of years to develop from the charcoal civilization to the nuclear energy civilization, and now it still has not reached the energy civilization, I have to say that the foundation is really important.

Earth Star also encountered the problem of energy shortage, but the problem encountered was quickly solved, when the oil reserves were still very considerable, there was early nuclear fission, and now there is a nuclear fusion reactor, and the sources of energy are diversified.

This situation is something that this world does not have, and the way this world obtains energy is too simple, and it has a lot to do with the innate conditions.

Since there is no problem with the instrument, he is ready to go to the place where the upper echelons of the Floating City are located, ready to ask for a request, the situation on the battlefield just now, I believe the other party has seen it.

Now the entire floating city has suffered a serious blow, and it is in ruins, and it can't bear the slightest blow.

Moreover, he also has his own hole cards, and he doesn't believe that the top management of the Moon Butterfly Clan will make a wrong decision.

Thinking of this, he left this place and flew to the place where the other party was most likely to appear, and dozens of minutes later, Zhou Yun came to a place, and sure enough, one of the high-ranking members of the Moon Butterfly Clan was here.

"Your Excellency, you know me."

After saying this, Zhou Yun waited for the other party's answer.

When the high-ranking member of the Moon Butterfly Clan heard someone shouting at him, he turned around, and when he saw Zhou Yun's full appearance, he immediately showed a look of surprise.

He is no stranger to Zhou Yun, speaking of which, the victory of this war has a lot to do with Zhou Yun, if it weren't for Zhou Yun disrupting the military deployment of the Li Mo clan, the loss of the Moon Butterfly clan would definitely be greater than that of the Li Mo clan.

"Of course I remember, if it weren't for Your Excellency, the loss of my Moon Butterfly Clan would be immeasurable, I don't know if I have anything to help you?"

Zhou Yun raised his opponent's words, and secretly said in his heart, sure enough.

Since the other party asked him to make a request, he naturally would not shirk it, this middle-aged man of the Moon Butterfly Clan has a status of at least the top ten in the Moon Butterfly Clan, if the other party says Zhou Yun's request, those people will also seriously consider it, not to mention that Zhou Yun's previous performance on the battlefield has left a deep impression in the hearts of these Moon Butterfly Clan high-level officials.

He is wearing a meteoric steel suit, and when he appears in front of those people, he will definitely be recognized, and when the time comes, I believe that there will be no objections.

I have learned about the temperament of this race before, and I naturally have a great grasp in my heart.

He was naturally very happy that he had received the other party's promise, but he knew that the other party was now busy restoring the construction of the city and did not have time to go to the database with him.

However, the other party gave him a token and told him that he could use the token to enter that place and store the database of materials and documents, unlike those secret areas, which require other high-level officials to have the ability to authorize.

Holding the token of the high-level of the Moon Butterfly Clan, Zhou Yun went to the database where the Moon Butterfly Clan stored the information, and after explaining his intention to the guards, he took out the token.

The guards of the database saw the token and didn't dare to stop it, so they let Zhou Yun enter this place, and before entering, he took off his meteorite steel suit and stored it in a locker.

He wasn't worried about the theft of his Meteorite suit, as soon as a stranger moved, Ryutsuki would warn him, and without his permission, other creatures wouldn't be able to get close at all.

After entering the database, Zhou Yun had a feeling of going back to when he was young when he entered the library, everything was so similar, however, the location of the two was different, and now it was in an unknown world, and besides, these books were all electronic, and it felt like reading it like a paper book.

However, since it is to obtain information, the form of information is no longer important, as long as he can figure out what the black crystal is, it is good information.

According to the instructions, Zhou Yun came to an electronic material, which uses holographic projection, just like a real book, with a few large characters written on the first page of the information, and the study of the dark spirit crystal is explained in detail.

Seeing these words, he knew that he had found the right one, picked up these materials, and these virtual materials appeared in his hands, and the materials on the bookshelf were still there, seeing this situation, Zhou Yun felt that the materials in his hands were copies of the original materials.

The use of virtual technology has undoubtedly made some things easier, and copies of these materials can be discarded in the recycle bin after reading.

After taking out these materials, Zhou Yun came to a reading room and read them carefully, the language and characters in it, through previous learning, basically knew everything, and occasionally a few unknown words and symbols appeared, and also speculated through the surrounding sentences.

Closing the information, Zhou Yun appeared in his mind, from these materials, he knew the origin of these so-called dark spirit crystals, it turned out that hundreds of years ago, there was a race that discovered this kind of thing, and inadvertently threw it in the burning coal, but after a day, it was found that there was no damage in the slightest, and it was still as black as ink, like a piece of black crystal.

This strange phenomenon immediately aroused the curiosity of the alien creature, but he couldn't study it himself, so he handed it over to the upper echelons of the race, and in this way, the research of the dark spirit crystal officially began.

It has been developed for hundreds of years, to such an extent, but from these materials, he has not obtained anything useful, and now there is one last kind of information left, which he hopes will be gained.

Time passed slowly, and Zhou Yun was also very happy in his heart, because he got what he wanted, threw all the materials he had seen into the recycling bin, and he walked out.

Now, two hours had passed since he entered the data room, and after he came out, he did a full-body scan and left with his meteoric steel suit.

After entering the library just now, the token on his body shattered, apparently, it was a disposable item.

He didn't have any opinion in his mind about this situation, once or again, he had already gotten what he wanted, and even if he had the opportunity to go to that place again, he wouldn't have any interest.

Returning to the laboratory again, he had a feeling of being in a different world, and now, after reading those materials, he knew in his heart that there was a long way to go to study that kind of dark spirit crystal.

The races of this world have been studied for hundreds of years, and there are not many things obtained, but with this foundation, it will also make his research path more convenient.
