On the busy streets, the neon lights flickered back and forth, the endless stream of people went back and forth like ocean waves, back and forth, the night sky of the city looked particularly clear in the frozen air, Zhou Yue stood on the top of the building and looked up at the starry sky, and slowly looked down at the mottled city, she began to can't tell whether this is illusory or reality, the entangled dream made her sleepless all night, and from time to time a few familiar strangers appeared around her. She paced a few times on the edge of the roof in high heels, and a kind of thought germinated in her heart, and she kept silently saying to herself: "Everything is illusory, come back to reality!" Let's get back to reality! Suddenly, she opened her eyes, looked at the flowing traffic, and the tears that flowed from her eyes could not be stopped, and she knew that it was not the end yet.

Liu Fei and the clones lingered for a few minutes where they met the sacred tree, but there was no sign of the tree.

"Sometimes a lot of things are not what you want to see...... said the cyborg

"We just wondered how this big tree disappeared, it was here, and I could vaguely smell it in the air." Liu Fei said

"Don't force it if you can't see it, we have more important things to deal with." The clone said to Liu Fei

"Okay, listen to you, we need to have more important things to do." Liu Fei said

In the factory inside the gate of time, the machine resumed production, the memory liquid bottle by bottle was transmitted from one end to the packaged box, the robot quickly loaded the packaged package into a huge wheeled cart that could be rowed, ready to be transported directly to the cyborg spaceship, Uesugi looked at the whole factory running in an orderly manner, did he have everything that happened in this factory some time ago in his mind, he remembered the fragment that Liu Fei said to him about going home, "home" Thirty years later, this word appeared strange and familiar in his ears and began to ripple, and the aftermath lingered. He lowered his head and began to recall the bits and pieces of his past youth, tears began to appear in his eyes, he began to regret his actions, and locked Liu Fei here, a young man who had suffered the same thing as him back then, and began to follow his path again under his decision......

Uesugi is full of contradictions, he walks and looks at the robots walking back and forth around him, on the surface it seems to be orderly, but everything is so lifeless, the efficiency of the machine age has a qualitative leap, but in terms of spirituality, it is step by step, so that human beings have come to the single-plank bridge on the edge of the cliff. Humans will be judged by the machine if they violate the mechanism set by the machine, which has been in place for 70 years, and no one can resist it, and they can only obey in order to live. There are thirteen such factories running simultaneously in this time gate, they are independent of each other, but they are connected to each other, and if there is a problem with the instructions of one factory, the other factories can directly sense it. In addition to this factory, the other factories are managed by the rest of the "humans".

"Where the hell does this belong?" Liu Fei asked

"This is in the middle of the galaxy, where the kinetic energy of all the planets comes from, and here is the Silver Core." The clone said

"How do you know?"

"According to the data given by the probe instruments, and, moreover, what we saw from the instruments on the cyborg spacecraft that day."

"Don't you feel like it's special here?"

"What's so special?"

"You try kicking a rock."

Liu Fei walked to the side of the road and saw a small stone and kicked it with his foot as the clone said, only to see the stone fly quickly from the ground into the distance, the stone disappeared instantly, they looked at each other and felt very curious, Liu Fei was just about to speak, the stone flew back according to the original path, and fell in place.

"All the material that flies out of here is gravitationally pulled back to its original place, and it's back to the starting point." The clone said

"What does this mean?" Liu Fei asked

"This is the center of the Milky Way, and all the laws come from here." The clone said

"The gravitational force is very fast here, causing us to have a lot faster time here than we do on Earth or Gliese 581d, and that's why we feel like time is passing very slowly here, the slower our speed, the faster the time outside, and sometimes with the difference in the strength of gravity, the speed of time will also vary, in short, it's relative." The clone continued

"According to what you mean, all matter is absorbed back by gravity, and so should the signal transmitted here." Liu Fei said

"You're right, so they use this inertia to quickly retract the signal sent with the gravitational inertia, which saves a lot of unnecessary resources, and the signal is completely attached to the gravitational field." The clone said

"Wouldn't it be a great harm to the people of Gliese 581d to turn off the signal here and stop processing at the factory? Can we think of a way to do both? Liu Fei said while thinking

"Don't forget, Liu Fei, the purpose of our here is to turn off the signal, and we also need to go to Gliese to see what is going on, because our real purpose is to restore the health of the people of the planet, not to become cyborgs." The clone said

"You're right, let's wait until we see what's going on." Liu Fei said

After saying that, Liu Fei and the clone returned to the secret room of the factory, and Uesugi came over at this moment.

"How are you staying here?"

"It's okay, but I'm not used to eating." Liu Fei smiled awkwardly as he spoke

"Hahaha, that's right, the hospitality is not good, we'll have a good meal later." Uesugi said

"Uesugi-sama, I don't know something, we saw the sacred tree before we came, and I never understand why it disappeared, and I heard that you have also seen this tree, I wonder what is the difference between this tree?" Liu Fei asked

"This tree is a little different, I saw it on an island in the ocean back then, and I got here through the guidance of a drifting bottle."

To tell you the truth, sir, we also found clues through the drifting bottle before we came, and we came here step by step, and the drifting bottle is strangely the same as the one found here, with ancient Eskimo characters written on it, and I once went to a cave in Greenland with a friend to see these words, and understood part of them, and strangely enough, I completely forgot all about it when I got out of the cave. Moreover, I also saw a series of drifting bottles on the river where I came here, and I wondered if it was some kind of coincidence, or if the bottle was trying to send a signal. Liu Fei said

When the two clones heard what Liu Fei said, they remembered that they had picked up a few bottles from the edge of the waterfall they had seen outside the passage here that day, and they took the bottles out of the bags they were carrying.

"Isn't that it?" The clone said, holding the bottle

Uesugi and Liu Fei saw the bottle and stepped forward to take a closer look, convinced that it was the bottle they saw.

"Yes, it's the bottle with the note in it." Liu Fei said

"No way, I've never seen a drifting bottle here, there are no humans here except me, this drifting bottle is a mystery."

"Mr. Uesugi, my friend Frank said that he found a building here with the bottle upstream, and the bottle was flowing out of the building."

"Is there such a thing? There are no buildings here except for the factory, could it be your friend's hallucination? Uesugi said

"Don't worry, my friend is very right-minded, what he sees can't be an illusion, then again, isn't this bottle just right here?"

"The waterfall outside the factory flows down, and the bottle can't appear in the upper reaches of the waterfall, so let's go to the waterfall outside the factory to see it, and as for the tree, I really can't explain why it's here, I came here through it, and I think I'm cursed by this tree. And you ...... You have all seen it, but you are safe and sound, and time will answer you. Uesugi continued

"Then let's take a look at this drifting bottle first!" Liu Fei said

After speaking, Liu Fei, Uesugi and the clone cyborg put on a protective suit that can dive, and came to the waterfall outside the factory passage, the circular waterfall is particularly spectacular, under the light of the light, eight rainbow bridges were erected in the center of the waterfall, and the water quickly flowed from them. I saw several drifting bottles around them, the bottles went down along the water flow, and the strange thing is that when the bottles flowed downstream, several bottles would repeatedly emerge from the water upstream, and several people felt very strange when they saw this scene, and prepared to dive to find out...

At this time, the factory is in full swing processing memory liquid, and the day of the ship's departure is getting closer and closer...... The electronic clock on the factory machine moves minute by minute......
