"What's wrong?" Wang Lin asked as soon as he got closer.

"What do I feel, Lao Zhang?" Xiaoyu looked at the people who came around, but she didn't notice Zhang Heng and asked.

Everyone turned their heads to look around, and finally saw a bright spot coming this way, and they were speechless, where did they run.

As soon as Zhang Heng stopped beside Xiaoyu, he immediately heard the queen's prompt, and his heart was overjoyed, this three-dimensional space in space is too sinful, and the ghost knows where this entrance is hiding.

The rest of the people heard Zhang Heng's surprise and immediately understood that this was found.

"Here?" Xiaoyu asked.

"Well, but I don't think I can get in yet."

Everyone waited here for a long time, and Xiaoyu shouted, "Look." ”

Under Xiaoyu's finger, a drop of liquid slowly condensed from in front of him.

"Catch me."

Everyone immediately put their hands on Zhang Heng's body according to his words.

"Hey, won't you take me on the back, what are you doing in front of me?"

Zhang Heng felt that there were several people crowded in front of him, and he couldn't see it, so he shouted.

The few people in front coughed dryly, flew down, and began to grab Zhang Heng's legs.

Zhang Heng looked down at the few people holding his legs at his feet, a chill swelled up, and he shook his spirit, and then reached out to touch the place where the liquid came out.

"Captain, you see they're gone." The people on the ship suddenly noticed that the group had disappeared and shouted.

"Well, make a note of the coordinates, we'll wait here."

Zhang Heng and his entourage felt that their eyes lit up, and Zhang Heng's feet had fallen to the ground.

A few people at the foot looked up, quickly got up from the ground, and turned their heads to look around.

It's a small space, only about forty or fifty square meters, very simple, surrounded by bookshelves full of books.

The rest of the people were afraid that the books would not dare to reach out and touch them without touching them, lest they break them.

Zhang Heng reached out and took a copy from the shelf, it was very heavy and cold.

"It's made of metal." Zhang Heng wondered.

When the rest of the people heard this, they reached out and touched the book in Zhang Heng's hand, and it was indeed metallic, but the flexibility was terrifyingly strong, just like ordinary paper.

Everyone immediately reached out and touched the books on the shelves, and after making sure that they were metal, they took one from the shelf.

Zhang Heng opened the writing in his hand, and there were a few words written on it--the first chapter of physical training.

Damn, what a bullish feeling, is it those cultivation methods in it?

Zhang Heng's heart was pounding, and he quickly opened it and looked at it, but unfortunately it was not suitable for his own world, because the rules of the world seemed to be a little different, and who had seen the legendary aura.

"Citation, engine chapter." Suddenly, Luo Yun shouted.

Everyone immediately gathered around, Luo Yun quickly turned a few pages, his eyes widened, "Oh my God, it's those high-tech engine technologies." ”

Everyone was shocked, and their hearts were overjoyed, what is missing on the blue star now is these engine technologies, although the current technology has improved a lot, but these technologies are still very backward, and compared with the technology in those science fiction movies, it is countless levels worse.

"It's useless, scientists don't necessarily have access to these technologies now." Xiaoyu said suddenly on the side.

The words of light rain are like a basin of cold water directly poured on everyone's heads.

Everyone thought about it carefully, and it was indeed the case, the knowledge gap was too big, and they felt that it was simple, and they might not be able to understand it by the Blue Star scientists here.

"Hey." Everyone sighed, this is a treasure mountain but they don't know how to start.

"It doesn't have to be unusable." Zhang Heng said loudly, "We can find some basics and give them out little by little, I think there will always be some knowledge that can be connected with the current science." ”

"Well, what Lao Zhang said is right." Xiaoyudian praised.

The rest of the people are also sure in their hearts, among the knowledge left by Luo Cheng, there must be those worlds with low technology, just like Zhang Heng turned to the physical training chapter, and at first glance it is used in the so-called cultivation world.

After having a reassurance, everyone immediately picked out a bookshelf and began to check it.

"Damn, weapons, neutron bombs."

"The making of the Space Ring. Day!!! ”

"Teleportation Circle Arc !!"

Immediately, all kinds of scolding sounded in this room, and this Nima couldn't understand it at all.

After touching it, several people sat on the floor and sighed, "Hey, Nima doesn't feel like I need it." Wang Lin sighed.

This space ring looks like a divine object, if you have one, how good it would be, you can go out without something.

"Long-distance teleportation is also very good, if we have this, we can directly transport troops and supplies back and forth in several major bases." Bai Yun sighed.

"In terms of space, don't think about it for the time being, under the influence of that kind of lifeform, space interference is very serious and unsafe." Zhang Heng shook his head.

"Let's sort out this knowledge, I think this knowledge seems to be closer to the current level of knowledge at the lower level, as for the upper level, I think it's better to keep it for now, and talk about it later." Xiaoyu said when she saw that everyone was in an unhappy mood.

Everyone nodded, Zhang Heng asked each person to be in charge of a bookshelf, and then photographed the bottom two layers of books, because the knowledge in these two layers is the closest to the current science, and it will be foggy if it is high.

If you have time to engage in those, it is better to take advantage of the past few years to directly improve some combat power.

As for those martial arts knowledge, Zhang Heng also picked some of the most basic ones, which should be achievable now, and handed them over to the Federation when they are ready to come out.

While the rest of the people were busy checking those who had a little more knowledge, Zhang Heng came to the balcony of this room.

Gently push open the glass door and enter the balcony, which is quite large, with some potted plants in the corner.

Zhang Heng took a closer look, thinking that the liquid outside was leaking out of this potted plant, although he didn't understand how it got out, but it was okay, there were many things he didn't understand.

From the balcony, the surroundings are white and cloudy, and you can't see the space outside, and it seems that there are still some differences from the courtyard on the first floor.

After everyone was busy, the group came out of it, reappeared in space, and returned to the spaceship to ask, it turned out that several days had passed, and it seemed that the time passed inside that people could not detect the speed or slowness.

After getting what they needed, Zhang Heng and his party returned to the moon base and handed over the basic knowledge they had gained to Commander Tom.

Commander Tom was holding the stack of printed things, and his mouth was so long that he couldn't close it.

"Quick, quick, let the best military scientists come here." Tom, who came to his senses, immediately called out to the staff officer.

Zhang Heng and the others will stay at the moon base for a while, one is to rest, and the other is to see how much knowledge these scientists can analyze, if these can be completely digested, Zhang Heng is ready to take some out.

The scientists looked at these various materials in their hands, and several of them fainted with excitement, especially the engine technology in this knowledge, which is currently the most lacking.

As long as this knowledge is mastered, the time to travel to and from major bases can be shortened by switching to a new generation of engines.
