At this time, Zhou Yun could feel that the Moon Butterfly Clan man was hostile to him, that is, the kind of hostility that faced a rival in love.

Seeing this situation, he couldn't cry or laugh, he didn't expect that he was inexplicably considered a rival in love, he didn't have any idea about Yueyu, he didn't want to have an interracial love, as long as the man of the Yuedie clan didn't provoke him, everything would be fine.

Hearing the other party's explanation, Zhou Yun also knew why the other party was here, it turned out that this annual science and technology exhibition was hosted by the high-level of the Moon Butterfly Clan, and every member of the Moon Butterfly Clan was required to come.

Many young people are very impetuous and don't want to come to this kind of place at all, so the high-level of the Moon Butterfly Clan will take coercive measures.

Knowing the reason, Zhou Yun was very surprised, he didn't expect that the high-level of the Moon Butterfly Clan would be so frustrated that they would take coercive measures, but, thinking about it, this kind of science and technology exhibition is too boring, and only some professionals will be interested.

He didn't know what the higher-ups of the Moon Butterfly Clan thought, but it was none of his business, in this world, he just wanted to figure out what the black crystal was as soon as possible.

It had been hundreds of years since this kind of thing was discovered, and he felt that the races of this world must have a unique understanding of this kind of thing, so he wanted to go to the library of the Moon Butterfly Clan now.

However, this matter is not in a hurry, and he has not yet mastered the language and writing of the Moon Butterfly Clan, so even if he goes to the library, he will not understand what is recorded in the book.

In the past two days, as long as he has free time, he will go to Yueyu's residence and ask the other party to teach him the language of the Yuedie clan, his learning ability is very strong, no matter what he learns, he can master it in a short time, and the language of the Yuedie clan is no exception.

It only took one day for him to basically master the other party's language, only some more esoteric language symbols, which he did not master, in his heart, the language symbols he currently mastered were enough.

He could still see the surprised expression on Yueyu's face now, the other party didn't expect that Zhou Yun had mastered the language of the Yuedie clan in just one day, and this world didn't have the ability to transmit knowledge, and it also needed to be learned.

Zhou Yun noticed Yueyu's surprised expression, smiled, and was not proud, the reason why he learned this alien language was to avoid his eyes being black and not being able to understand the contents after going to the library of the Moon Butterfly Clan.

If he could bring Ryuki in, he wouldn't need to be so troublesome, but for the sake of respecting the other party, he wouldn't bring Ryuki to the library, which was a matter of principle.

The most important thing now is how to enter the library of the Moon Butterfly Clan, the ordinary library is not in his consideration, only the most important library of the Moon Butterfly Clan is his goal, where can he find the answer he wants.

However, he didn't know how to enter that library at all, after all, he was a foreigner, and he didn't contribute much to the Moon Butterfly Clan, and if he wanted to enter that library, it could be said that it was almost zero.

Suddenly, a shrill siren sounded in the floating city, he had just come to this place, and he didn't know what it meant, but Tsugeta was different, she had lived in this city since she was a child, so she naturally understood what this siren meant.

Yueyu's mind drifted to the time she was ten years old, and at that time, the city also sounded this kind of alarm, that kind of scene, she still remembers vividly, every night, when she thinks of that scene, she does not feel sleepy.

With this level of alarm reappearing, she can only pray in her heart, praying that the tragedy of the last time will not be repeated.

The creatures of various races who were watching the results of scientific and technological research heard the alarm, their bodies suddenly stopped, and then they quickly left here, their steps hurried.

At this time, even if Zhou Yun didn't know what the alarm meant, he also knew that the matter was big, otherwise, the creatures of all races here would not have such a look.

"Mr. Zhou Yun, this alarm indicates that the floating city is in danger of being destroyed, and I experienced it once when I was ten years old, and that time, I lost my parents."

Speaking of this, Yueyu's face was full of evil energy, and her heart was obviously not calm.

Hearing Yueyu's words, Zhou Yun's eyes showed surprise, he didn't expect that the other party would have such a tragic encounter, and he didn't know what to say now.

He had always been curious about where Yueyu's parents were, and at first he thought that they had something to do, but he didn't expect that this would be the result.

Zhou Yun felt that the other party's experience was very similar to him, and his parents were not by his side, but the only difference was that the other party's parents had been confirmed to be killed, but his parents were only missing now, and he still didn't know if they had finally passed away.

When he was on Earth, he had not given up looking for his parents, but until he came to this world, there was still no news, and there was no hope in his heart.

At this time, there were not many creatures at the scene of the entire science and technology exhibition, seeing this situation, Zhou Yun wanted Yueyu to say goodbye, he wanted to rush back as soon as possible, only when he returned to the laboratory and put on the meteorite steel suit, he was at ease.

From Yueyu's mouth, I learned that this level of alarm is the highest level, indicating that the floating city is facing an unprecedented disaster, and after the last alarm of the same level, there is not one in ten creatures in the floating city, and it almost became a dead city.

Hearing Zhou Yun's farewell, she nodded, she has to go back to prepare now, otherwise, in the face of such a situation, there is no preparation, and the hope of survival is very small.

After putting on the meteoric steel suit, he flew to the top of the floating city in a small rented transport aircraft, and immediately saw a surprising scene, it turned out that the outside of the city was full of flying machines, densely packed, if people with dense phobia saw this situation, it would definitely be very uncomfortable.

Zhou Yun didn't have a phobia of intensity, but seeing this situation, it was not easy to feel good.

Judging from the appearance of these flying machines, it seems that they are the Li Mo clan flying machines that are chasing and killing Yueyu, and they were only a small team and twenty flying machines before, but now there are tens of thousands of flying machines.

The most important thing is that he saw ten one-thousand-meter-long space battleships, and the gun barrels on the battleships glowed with cold light, which was not easy to mess with at first glance.

Judging from the current situation, it seems that the Li Mo clan is attacking the floating city, but I don't know what the result of the battle between the two races will be.

However, from the fact that the Limo clan did everything to attack the Moon Butterfly Clan, it can be known that the energy crisis of the Li Mo clan has arrived, otherwise, they will not let go, and the strength of the Moon Butterfly Clan is not much worse than that of the Li Mo clan.
