When Liuyu and the eight of them returned to Blue Star from the 47 wormhole, Black Egg had already cleaned up all the probes arranged by Team 47 on Planet 47. All traces of the Blue Star Civilization on Planet 47 have been erased, and even some of the footprints and ruts of Team 47 on Planet 4 have been swept away, which is really the same as the Blue Star Civilization has never been to Planet 47.

After they returned to Blue Star, the black egg also accelerated the closing speed of the 47 wormhole, and the time speed of the 47 wormhole was accelerated by a factor of 10, so that the closing of the 47 wormhole could be observed with the naked eye.

On the side of Blue Star's 47 wormhole base, the sand and dust that had been inconspicuous and slowly falling before began to become obvious, and the speed of landing was almost exponentially increased.

At first, the dust was like a mild sandstorm, turning the entire base into a gray sky. Eventually, the 47 wormholes began to become particularly violent, with dark matter and dark energy being ejected like fireworks.

The rate of annihilation of dark energy and dark matter has also become particularly fast, and they are ejected into the air and quickly become ordinary dust.

47 The wormhole seems to have turned into a well, and countless sand is constantly spewing out from the mouth of the well. When the sand erupted completely, the 47 wormhole disappeared completely.

This process went very quickly, and it took only about 10 minutes for the artesian jade to come out of the 47 wormhole and disappear from the 47 wormhole.

Liuyu knew that it was the egg civilization that accelerated the closure of the wormhole, and they watched the final performance of the 47 wormhole with great interest, and paid tribute to them while sighing at the science and technology of the egg civilization.

How many people, or how many civilizations, can be strong and not bully the weak, and this kind of behavior deserves the respect of others.

It was different for the people at the base of 47 wormholes, and the outbreak of 47 wormholes was very sudden for them. Researchers had predicted that the wormhole would close linearly and gradually, but they didn't expect it to accelerate suddenly.

Among them, Miao Qing was the most depressed, she worked hard to collect so much data to verify the speed of change of the 47 wormhole, looking for the change law of the 47 wormhole, but she didn't expect the 47 wormhole to change as if there was no law, and it was gone.

Not to mention the combatants, they thought that something terrible was going to come out of the 47 wormholes, and they all quickly prepared for battle, and the guns and guns were all aimed at the mouth of the 47 wormholes.

After Liu Yu and the others landed, they were quickly called into the command room.

There were quite a lot of people in the command room, the black general was there with two staff officers, and Miao Qing was also with two scientific researchers. In addition, Qingfeng Mu of the Silk Civilization also came, and this time she didn't come alone, she also brought two scientific researchers from the Silk Civilization.

The egg civilization that I accidentally came into contact with this time, their technological level is much higher than that of the silk civilization, so the silk civilization also attaches great importance to the intelligence of the egg civilization. After all, any civilization wants to make itself stronger, and it is rare to encounter a civilization that is much stronger than itself, but will not fight with itself, of course, I hope to collect their intelligence in as much detail as possible, and learn from the experience of technological development or civilization development.

As the main contact of the egg civilization, Liuyu made the main statement at the meeting. Regarding the part of science and technology, Miao Qing and the three of them had a heated discussion with two scientists from Tao Wenming.

However, the focus of the black general and Qingfeng Mu is the military capabilities of the egg civilization, such as their means of communication, means of attack, etc., especially the great civilization can block quantum communication and control time, these two technologies are simply miraculous.

As for why the Egg Civilization didn't attack Blue Star, and they talked so much about Liuyu, no one knows.

Looking back at Heidan's performance, he looks like a soldier or a killer, he is carrying a gun and fully armed on a mission, and in the process of performing his mission, he accidentally meets a little kid named Liuyu.

Any piece of equipment on Black Egg's body can easily kill this little brat. But he didn't, but talked a lot to the little boy with great interest.

Although Liuyu is a little boy who keeps asking questions, he really only has to listen. What the black egg wants to say, how much he wants to say, the initiative is completely in his hands, and he also sneers at the Blue Star Civilization from time to time.

Liuyu, or the entire Blue Star, is a little kid who can be killed at any time in front of the black egg.

Liuyu's luck this time was really good, he met an extremely dangerous person, but this person did not embarrass him, but taught him a lot of things.

This is very similar to the Silk Civilization, which did not invade the Blue Star after coming to the Blue Star, but kindly helped the Blue Star to progress and gave the Blue Star a lot of things.

The difference is that the Silk Civilization has shown complete goodwill so far, while the Egg Civilization has shown neither kindness nor malice.

Of course, the most amazing thing about the egg civilization is that they will close the wormholes, and all the wormholes that can be connected to their home planet will be closed by them.

The Egg Civilization is also scattered throughout the universe and will communicate with other civilizations, but their home planet still exists. Therefore, the egg civilization pursues a strategy of protecting the home planet while communicating with the outside world.

This should be the biggest difference between the egg civilization and the silk civilization, the home planet of the silk civilization has long since ceased to exist, and the humans of the silk civilization can only find new planets that can survive in the whole universe, and then integrate into them. The Silk Civilization helps others develop technology, and then borrows other people's planets to multiply, and eventually becomes one with them.

As for why the Silk Civilization finally chose the path of peaceful development, Qingfeng Mu once said that their home planet was too arrogant and domineering in the early stage, and after invading several planets, it was discovered and wiped out by a higher-level civilization, and the surviving Silk Civilization humans chose the path of peaceful development.

Of course, this is only one side of the Silk Civilization, and Blue Star does not have the ability to verify the authenticity of this statement, nor can it investigate the history of the Silk Civilization.

In addition, there are now countless branch civilizations of the Silk civilization, and no one can guarantee that all of them are still adhering to the path of peaceful development. Even Qingfeng Mu himself said that Qian Wenming himself could not guarantee it.

The Silk Civilization and the Egg Civilization are both civilizations whose technology is far higher than that of the Blue Star Civilization, and they also need to rack their brains and work hard for the survival of their own civilization, and they really don't know if they can survive well in the cosmic environment with the current level of science and technology and the speed of progress of the Blue Star Civilization.
