When Yin Cheng and Bai Yu arrived at the lunar base station, they were carefully examined, and Yin Cheng's life span was undoubtedly longer, but Bai Yu wasn't far behind.

    The first time I saw it, I thought it would be a good idea for me to get a new one, but I didn't know why it was put in the backup system.

    Yin Cheng also searched for some information about the intelligent system on the internet, but did not find any useful information.

    As Yin Cheng looked at the search on the Star Network, a sentence from the previous system suddenly flashed in his mind, "...the Capay High Civilization is a third class civilization..."

    Yin Cheng thought about it and typed in the word "low level civilization".

    It's a great deal more than that, Yin Cheng slowly tapped on the related search terms, from "low level civilization" to "high level civilization" and then to "civilization level". "Second class civilization" and so on.

    It took a while to click on it before pretending as if it was unintentional to click in third class civilization.

    However... the third class civilization was just a legend.

    Having searched for these things, Yin Cheng searched in the same way for the issues he was looking for, including the things about time and space retrieval and rebirth.

    The Technology Research Institute of Time Regression had been working on it, but there was no news of success on the Starnet, and the search about rebirth was more of imagination and stories.

    Moreover, although the system devices on the Starnet also carried spatial compression, but they were all fixed size, there was no such thing as more energy to open more.

    The things he wanted to search for were not found, and Yin Cheng looked at the system on his wrist with a little surprise in his eyes.

    "Brother Cheng? What's going on?" The first thing you need to know is that you can't afford to buy a new one.

    The first thing you need to know about the system is that it's not just the system, it's also the system.

    The system didn't reveal too much even though Yin Cheng and Bai Yu asked a lot of questions, and finally said that there was only one chance to go back in time and space, and that even if there was more energy in the future, they couldn't go back again.

    Since they couldn't find out about those ethereal tertiary civilizations, Yin Cheng and the others didn't dwell on it and lived on the moon at ease.

    The environment in the base station was similar to that on Earth, and the space was not small either, besides the place where the Starnet studied, there were also places for sports and fitness, chatting and resting, in addition to their activities here, those starfighters who were on rotation were also present at the meeting.

    The three hundred people who came up to study have all walks of life, naturally there are also military people, they have a lot of questions about these "interstellar soldiers" naturally, it did not take long for aliens and earthlings to become friends.

    The first two years on the lunar base station is actually quite boring, most of the time other people are studying, star network star network off the study, Yin Cheng and their leisurely and those three hundred people are a bit out of place.

    But then Li Shuhan and the others took the initiative to contact the Chinese among the three hundred people, and occasionally would transfer to them the starnet time limit that they could not use idly, their relationship was much better, although they did not know if the other party was sincere or for the time limit, but at least on the surface, everyone was melting cha cha cha.

    Li Shuhan didn't really care if they were sincere or not, as long as they weren't isolated out and maintained a superficial friendliness was enough.

    Two years passed by and they were about to return to Earth for the first time.

    This time, Yin Cheng and Bai Yu were also planning to go back with them, after all, the first two years were definitely safer than later.

    If they didn't go back this time, when the knowledge they carried with them this time was brought back, Earth would probably have to undergo a major blood change, and the next few years would be even more chaotic.

    It wasn't like Yin Cheng and the others had done nothing in these two years, at least while the others were learning various specialized knowledge, Yin Cheng had Bai Yu copy a few highly rated business books on StarNet and some of the already publicized methods of making small goods, intended as a gift for the Bai family.

    --Although the opportunity to learn on the Star Network was a compensation, it did not allow for direct data copy transfer, they could only look up what they wanted to learn and then record it down, of course, this record could be recorded on some electronic devices.

    The flying ship slowly descended, there were many people on the ground standing by waiting.

    "Cheng, look, it's my brother and the others." Bai Yu looked down from the window, looking for them he found Bai Xu and Bai Yi standing in the front row, somewhat excitedly tugging on Yin Cheng's arm and shaking it.

    "Mm." Yin Cheng nodded, looking at Bai Yu's excited appearance, suddenly hesitant to leave Earth and go to another galaxy.

    He himself was definitely indifferent, but if he brought Bai Yu, Bai Yu's family was still on Earth.

    The ship landed, the first to go down were also those three hundred people, Yin Cheng and the others waited until everyone else had left before going down.

    Although those three hundred people all knew about Yin Cheng and the others these special quotas, it was better not to expose too much in front of the public.

    "Yu Yu." Bai Xu and the others waited until everyone else had left and stayed here under Yuan Hongwei's acquiescence, finally waiting for the few people who came down from the flying ship.

    "Brother!" Bai Yu looked at Bai Xu with curved eyes, "You came to pick me up."

    "Yeah." Bai Xu also smiled, nodding and saying mildly, "Go home."

    Nothing major had actually happened on the ground in the past two years, the only thing that had changed was that there were more places to restore the network, because the plants and animals wouldn't be spewing out evolution again, and the evolved plants and animals left behind were all accounted for, and the various bases had sent people to collectively hunt and clean up the area with initial success.

    But also because there would be no more new evolutionary creatures, evolved plant and animal flesh became extremely expensive - because they increased supernatural strength, and there were still people who didn't believe in them who thought that eating them would stimulate supernatural powers.

    Of course, these are things that the state wants to promote and manage, and they don't have much to do with them.

    After eating at the Bai Family, Li Shuhan and the others were invited to stay directly in the Bai Family guest room again, and they didn't refuse, after all, they hadn't come back for two years, and this time they would only stay for a week, so they didn't need to rent a house outside again.

    In the evening, Bai Yu handed over the gift he had prepared for the Bai family to Bai Xu.

    The advanced study materials copied from the Star Network had been compiled since which three hundred people had returned, and a small portion had already been posted on the Internet, so it was naturally impossible for Bai Xu to guess what Bai Yu was going to give him.

    Bai Xu's eyes struggled a bit, looking at the look in Bai Yu's eyes completely for his family, the guilt was even stronger.

    Bai Xu opened his arms and hugged Bai Yu, looking at the other party, his lips opened and closed slightly, "Yu Yu, I'm sorry..."

    Bai Xu's tone was so far from his usual gentle and accommodating manner that Bai Yu was a little stunned at what he heard, before he realized what Bai Xu was saying.

    "Oh... "Bai Yu responded somewhat dryly, bowing his head, his newly happy mood lowered, and said in a small, somewhat hesitant voice, "Brother, I don't want to accept this apology... ..."

    Bai Yu used to really feel that his family was more important than anything else and that they were equally fond of him, but what he knew at the beginning of the end times first made Bai Yu feel cheated, and then the fact that they even let him go outside the capital was even more of a blow.

    Even though Bai Yu was protected by Yin Cheng at the beginning of the end times and didn't suffer too much, it still couldn't hide the fact that they could almost be considered to have given up on Bai Yu before.

    But even so...Bai Yu couldn't be ruthless enough to break with them.

    "No need to accept it." Bai Xu's eyes softened as he looked at his brother, reaching out to rub the top of Bai Yu's head, "We're the ones who did wrong."

    "Brother... "Bai Yu looked at Bai Xu and pursed his lips, his eyes a little red.

    Yin Cheng sat outside and waited for Bai Yu to come out of the study, as a result, Bai Yu just came out Yin Cheng saw the other side of the red eyes, a few steps to the side of Bai Yu, reached out to hold Bai Yu's hand, and asked Bai Yu in a low tone, "Who bullied you?"

    "No." Bai Yu shook his head in a small way, then hugged Yin Cheng and smiled out at Yin Cheng up in his arms, his eyes were red, but they shone with laughter and he didn't look wronged, and only then did Yin Cheng put his heart at ease.

    "Brother, we are going to sleep!" Bai Yu and Bai Xu said to each other, then dragged Yin Cheng away.

    "Brother Cheng, my brother just apologized to me." Back in the bedroom, Bai Yu lay on the bed and looked at Yin Cheng with bright eyes.

    Yin Cheng hooked his lips and smiled, asking Bai Yu, "Did you tell him to go to the base station next time?"

    Bai Yu shook his head, his tone with a little bit of leap, "Haven't told yet, and he hasn't even seen what my gift to him is yet."

    Yin Cheng looked at the smile on Bai Yu's face, his heart softened and his eyes also flashed with laughter, reaching out to rub the top of Bai Yu's head.

    Bai Yu was really easily satisfied, a family member's pleasantness without interest could cheer him up.

    "Brother Cheng, when do you think I'll tell them we're going to the moon next time?" Nesting in Yin Cheng's arms, Bai Yu asked in a low voice.

    "All can, if you want, we will return after two years, wait for the Earth's star network to be built and then leave, and then you will be able to contact them wherever we go... "Yin Cheng looked at the little young master in his arms, with a smile on his face and a soft voice, and said slowly.

    "Then let's wait until the star network is built before we leave!"

    "All at your service." Yin Cheng's eyes reflected Bai Yu's smiling face, and the corners of his lips were slightly hooked, revealing a smile as well.
