Xiao Yu only stayed in the Ursa Major dwarf galaxy for a short period of time, and after receiving Zhang Shengya and the Arrow Beast family, he embarked on a journey to the galaxy again.

This will be Xiao Yu's last return to the galaxy. At least, in the foreseeable future, Xiao Yu has no plans to return to the galaxy again. The current Xiao Yu, although he is not able to draw energy directly from space, but the progress of science and technology has allowed Xiao Yu to break the restriction that the sixth-level civilization cannot sail across the river system, and just by relying on the stars stored in his small universe, it is enough to sail from the Milky Way to the Andromeda Galaxy.

After becoming a seventh-level civilization, the small universe will be abandoned by Xiao Yu. The small universe has no meaning for a seventh-level civilization. Because the seventh-level civilization has almost fully grasped the mysteries of space, there is no difficulty for the seventh-level civilization to accept such a thing as mustard seeds in Sumeru. A seventh-level civilization can completely create a spaceship that looks extremely small in appearance but has an incomparably large internal space.

The Ursa Major dwarf galaxy is 100,000 light-years away from the Milky Way, and at Xiao Yu's current speed, it will take less than 500 years to cross this journey. During this time, Xiao Yu will complete large-scale industrial construction, building a spaceship that can destroy the entire Sweeper civilization. The theoretical research and development of space conversion weapons has been completed and will soon be put into practical production. Xiao Yu will use this weapon to destroy the most powerful weapon of war of the Sweeper civilization, the Neutron Warstar.

"Are you leaving the galaxy after destroying the Sweeper civilization?" On Mars, Zhang Shengya and Xiao Yu's phantom sat side by side, and Zhang Shengya asked softly.

"Yes." Xiao Yu said.

"I don't want to go." Zhang Shengya meekly leaned her head on Xiao Yu's phantom's shoulder, and said softly, "I'm tired of wandering, I just want to find a place." I live quietly with you. ”

"You can live on Mars forever, here, the starry sky you see will always be so magnificent, the sun will rise every day, there will be fixed spring, summer, autumn and winter here, there will be rain and snow, you will not feel the distance and loneliness of the journey." Xiao Yu replied, "The Beast Clan will also live here and accompany you. ”

"It's different." Zhang Shengya shook her head and said, "I want you to stay in the galaxy with me all the time." After the Sweeper civilization was destroyed by you. You are the most powerful being in the galaxy, and no one can disturb us. The time when I was controlled by the Taihao civilization made me feel a sense of fear for the dark cosmic starry sky. I'm afraid of the unknown and like to settle down. ”

"Haven't you thought about it all along?" Zhang Shengya turned her head and looked at Xiao Yu fixedly with her own eyes: "We are the last two remaining humans in the universe. You really didn't want to be with me. The intention to reinvigorate our human civilization? I can be Eve, if only you will be Adam. ”

Xiao Yu shook his head a little bitterly. "I've always seen you as my sister. If you like. If you want more people to keep you company, I can always create a large number of humans through biotechnology. ”

"Don't forget that in our ancient Chinese legends, the ancestor of creation, Nuwa and Fuxi are also brothers and sisters." Zhang Shengya continued. "What's more, we're not really brothers and sisters."

Xiao Yu stood up: "You have a good rest, No, Lina has already come to you." ”

Xiao Yu turned off the virtual display. Zhang Shengya looked at the place where Xiao Yu disappeared, and was stunned there. Lina had already come to Zhang Shengya's side and asked with concern, "What's wrong with you?" ”

"I'm fine." She shook her head faintly: "I don't want to leave, I want to stay in the galaxy." ”

"Me too." Lina said, "We of the Beasts think the same thing. The unknown dark universe terrifies us, and we like a stable life rather than wandering around. Although I really want to be with Brother Xiao Yu, I am also the leader of our race, and I can't let my personal feelings be the basis for determining the future of my race. ”

"Do you like your brother Xiao Yu?" At this time, Zhang Shengya suddenly asked.

Lina was slightly stunned and replied, "I like it." ”

"What kind of like?"

Lina smiled slightly and said, "Is there several kinds of liking?" ”

"Oh." Zhang Shengya replied a little lost.

The body structure of the beast and the human beast is not the same, the beast has only one gender, so in the group of beasts, there is naturally no such thing as love. Lina's feelings for Xiao Yu naturally can't be love. Because the beast doesn't know what love is.

"My friend, don't worry, even if Brother Xiao Yu finally leaves, our Arrow Beast Clan will stay here to accompany you. I have a good relationship with the leaders of the Pegasus civilization, and after Xiao Yu's brother leaves, the galaxy will be their world, and they will definitely take good care of us. Lina seemed to see Zhang Shengya's loss, so she comforted softly.

There was silence on Mars. The sun had set, and the earth was covered in infinite darkness. The night breeze blew, and it was slightly cool.

In the rest of the small universe, busy construction is underway. New spaceships have been built one after another, and the renovation of the old ones is also in progress. In the war against the Sweeper civilization, these ships will be the most powerful weapons of all.

Hundreds of years have passed, and Xiao Yu's fleet has reached the edge of the galaxy, once again detecting the gases escaping from the galaxy.

"Shenzhou civilization, are you okay?" Xiao Yu thought silently, "Where are you?" ”

Now Xiao Yu can already use some detection technology within the scope of a seventh-level civilization. Xiao Yu plans to find out the Shenzhou civilization first, and after merging with the Shenzhou civilization, he will find the traces of the Sweeper civilization, and finally destroy the Sweeper civilization.

Hundreds of thousands of extremely sensitive detection instruments have been dispersed into an open space with a radius of tens of millions of kilometers. The space of the entire galaxy is like a huge spider web, and Xiao Yu's detection instruments are like spiders lying on top of this spider web. Any subtle fluctuations in the spider's web will be detected by the spider, and similarly, within the scope of the Milky Way, any subtle spatial fluctuations will also be detected by Xiao Yu.

Xiao Yu believes that a long time ago, the technology that the Sweeper Civilization found out was similar to the technology he was using now. It's just that the difference is that the Sweeper civilization has achieved this with the help of the legacy technology of the seventh-level civilization, while Xiao Yu has achieved this through his own ability.

Huge spatial data poured into Xiao Yu's mind like a tide. A large number of spatial fluctuations with certain characteristics were eliminated by Xiao Yu in an instant. These excluded data are undoubtedly caused by natural phenomena, and they have no meaning to Xiao Yu.

After this data is excluded, there are far fewer suspicious targets left. After analyzing them one by one, Xiao Yu finally locked on a suspicious target.

"There is a great deal of high-speed curvature going on in this area, and at the same time, space seems to be distorting at a strange frequency, and through this distortion, a labyrinth-like effect will appear in this space. This is a seventh-level civilization relic. And the large amount of curvature navigation fluctuations and other fluctuations that appeared in this space should have been caused by the battle between the two sixth-level peak civilizations. ”

"Huh? What is this volatility? So strong? Hmm, it's supposed to be a Neutron Battlestar. Don't...... The Sweeper civilization is at war with the Shenzhou civilization, so much so that the Sweeper civilization has used all the neutron battle stars? Isn't the Shenzhou civilization very dangerous at the moment? Xiao Yu, who noticed this, suddenly tightened in his heart. The Shenzhou civilization that has its own presence is not the opponent of the Sweeper civilization, and after he leaves, how can the Shenzhou civilization be the opponent of the Sweeper civilization?

"The Shenzhou civilization is very dangerous at the moment." Xiao Yu quickly confirmed this matter, "It is impossible for the Shenzhou civilization to take the initiative to attack the Cleaner Civilization, then it can only be that the Cleaner Civilization is taking the initiative to attack the Shenzhou Civilization." And the Shenzhou civilization did not escape at the moment, is it because of the relics of that seventh-level civilization? ”

Xiao Yu quickly determined a conjecture in his heart, "No, you must not let the Sweeper Civilization get the relics of that seventh-level civilization." The Neutron Battlestar is already a weapon of a seventh-level civilization, and if you get this seventh-level civilization relic again, then it is very likely that some accidents will happen. ”

"The Shenzhou civilization occupies this ruin, and is using this ruin as a base to fight against the Sweeper civilization. Late will change, and I can't allow the unexpected to happen. After confirming this, Xiao Yu did not stop any longer, and controlled his fleet, at a speed of at least one hundred and eighty times the speed of light, quickly moving towards the position among the detection targets.

That location was thousands of light years away from where Xiao Yu was at the moment. It will take Xiao Yu about ten years to arrive.

More than ten years have passed in a hurry, and in these ten years, Xiao Yu has been paying close attention to the movements there. Thankfully, nothing has changed during this time.

Xiao Yu finally arrived here. The moment he saw the situation here, Xiao Yu breathed a sigh of relief in his heart: "I finally caught up, if I came a little later, the consequences would be unimaginable." ”

"Shenzhou civilization, I am Xiao Yu. Don't worry, I'll take care of the Sweeper civilization......"

Looking at the neutron battle star quietly suspended in front of him, Xiao Yu sent out this message lightly.

"Neutron Battlestar, today is the day you are destroyed......" (To be continued......

PS: The three chapters are finally complete...... It seems that it is the end of the month, so I ask for a monthly pass......
