It's a normal day, and the larger Star Rail is about to be built, this time with the Rhombolite battleship as the standard.

One kilometer long and four hundred meters wide, there are fewer weapons, mostly fuel with redundant parts of various systems.

Ai AA is leaving.

In a large ecological park under the Blue Star, Cheng Xin used a 3D printer to print famous paintings to decorate her future home, where she plans to spend the rest of her life waiting for the clouds.

A "Starry Sky" was printed, which was a famous painting by Van Gogh more than six centuries ago.

The pale yellow two-dimensional stars and moon hung high in the sky, and seeing Saddle Sima, Cheng Xin thought of the solar system that was becoming two-dimensional two hundred and eighty light years away, the earth that was being destroyed, and the billions of lives that were dying.

"Alas... It's really black. ”

With a sigh, she found a picture frame and framed it on her desk.

"Ma'am, Ai AA is coming down."

The housekeeper dawned and prompted aloud.

Cheng Xin nodded, went to the coffee machine to pour himself a cup of bitter coffee, and prepared a black tea for AA.

I don't know when she fell in love with the bitter taste.

"Friend, I'm leaving!"

Before I saw him, I heard his voice first, and Ai AA's capable voice came.

"Well, good luck." Cheng Xin hung an elaborate paper crane pendant on AA hair.

The thousand paper cranes are known as the meaning of good luck and peace.

Ai AA took a sip of black tea and asked, "How is the tea tree cultivated?" I want to pick a little tea and drink it on the way. ”

"Don't worry, it's all ready for you, there are some cocoa beans, and Dawn is packing."

"Well, thank you, by the way, I also have a gift for you, I have translated the high-fidelity game of "Sailing with Dreams" into the principle of optical path computers, and it and Sister Shuguang can spend a long life with you."

Cheng Xin choked up a little, "Thank you." ”

"Where's the port, I'll transfer it to you."

"Study." Cheng Xin took AA to the study, where there is a physical port that links to the 'tree-level' optical path computer.

After a busy time, the data in the pocket memory was transferred to the database, and it began to be decompressed and run.

At this time, AA noticed the painting on the desk.

"Did you paint this "Starry Sky" yourself?"

She asked, confused, that it looked like it was printed, but that the print should not be wrong in the details.

Cheng Xin replied puzzled: "No, it's printed, what's wrong?" ”

"Starry Sky has six distinctly yellowish stars, which is the right number, but the position and size are wrong."

Ai AA has taken the Ph.D. in art and naturally knows the famous paintings in history very well.

When she looked closely, she noticed that in addition to the different stars, the gray spire had also changed, slightly to the left and closer to the flame-like dark greenish-brown cypress.

Cheng Xin asked: "Shuguang, do you have this starry sky in your database?" Is it a typographical error. ”

"I searched the database, there are no such paintings, there may be something interfering with the optical path of the computer."

"It's almost impossible, the planetary defenses didn't detect the enemy."

AA pondered for a moment and thought of something that a Ph.D. in history must know.

She made a few strokes on the table, and three figures appeared on the wall, each with a number of black dots randomly distributed on it, each with a relatively large black dot in the picture, and a small arrow to indicate it.

Cheng Xin also knows these three pictures, which are the spells that Luo Ji cast on the 187J3X1 galaxy more than 400 years ago.

She looked at the starry sky, and it was the same thing, only more succinct: "Oh my God,! ”

The painting marks a location with the relative positions of six star systems, it uses the size of the stars to indicate the distance ratio, and with the relative position, with the distance ratio, it is easy to find them.

Dawn: "Found it, the marker is only 23.5 light-years away from the blue star, do you need me to send a probe?" ”

Ai AA shook his head and said, "No need, only our compatriots and Trisolarans know so much about human civilization. ”

"We did meet ghosts, they need help, Star Rail refueled, I want to go over and take a look."

AA thought of Taylor the Wall-Facer's Quantum Ghost Fleet project, which she remembered was reactivated by the Coalition Government.

This is the last line of insurance for the fleet.

It is difficult for quantum life to interfere with macroscopic reality, it belongs to another 'dimension', the required resources macro-civilization will not be used, and it will not pose a threat to macro-civilization, and the fleet will break away from the dark forest of macro-world in the form of 'dimensionality reduction' to avoid being hit.

But the downside, the universe is full of forbidden places for quantum life: the blind spot of intelligent subons that destroy quantum entanglement relationships.

Quantum life can indeed become an observer, changing the trajectory of light quanta from the quantum level.

Ai AA asked, "Dawn, are we out of the blind spot of Zhizi?" ”

The blind spot created by the alien civilization is very large and does not move, and the moving star system will sooner or later break out of the blind zone of the wise son.

"Wait, verifying."

The method of verification is very simple, just try to carry out quantum entanglement experiments, and if it succeeds, it will prove that it is detached.

Cheng Xin said worriedly: "They are all at sub-light speed!" What kind of technology can attack them? ”

Three hundred light years, too close to the solar system, the fleet will not stop at all, and in a state of sub-light navigation infinitely close to the speed of light, there is only one possibility:

"The attacker has an over-range strike method, which is the ability of a god, and there is a high probability that the fleet will encounter a god-level civilization spaceship."

Dawn: "Verified, indeed left. ”

"I'll go first, Dawn will carry out the Black Domain Project in ten days, if you want to get out of here, that's your last chance."

Ai AA got up and hurried to the elevator.

"Goodbye, friend."

Star Orbit docked in the Blue Star synchronous orbit, and immediately after the AA landed, the spacecraft entered a state of curvature acceleration.

For her, more than twenty years is just a few dozen minutes, and after exiting the speed of light, the radar begins to work.

AI report: "A large number of metal wreckage was found, and judging by the parts, it is a stellar-class battleship." ”

Stellar star, this establishment has been canceled, so, this is the StarUnited fleet that once parted ways in the four-dimensional cemetery.

The image came next, and the image made Ai AA shudder: hundreds of battleships collided together, forming an irregular metal ball, with its head pointing outward, proving that the fleet had tried to slow down desperately, and the speed had indeed slowed down, otherwise under the high-speed impact, the wreckage of the battleship would have turned into a vast interstellar garbage dump.

Ai AA's brain made up what happened at that time: when the fleets were separated by a light, they were traveling in a loose formation at sub-light speeds, and the spatial structure suddenly changed, and something intersected hundreds of parallel tracks, and the cars on the track did not have time to slow down and collided at the intersection.

"No, it only takes three minutes to accelerate to sub-light speed, and it only takes three minutes to slow down, and something at the intersection sucks them in, black hole?"

Ai AA docked the spacecraft next to a metal ball with a diameter of more than 100 kilometers, and sent miniature robots to search through the gap into the wreckage of the battleship.

There are many well-structured chambers in the wreckage, which are the key protection facilities of the electromagnetic law system, so that they can survive the impact.

Through the dug up database, Ai AA confirmed that this was the fifth formation of the First Fleet, and they had been in the four-dimensional graveyard for thirteen years before setting sail first.

Not a single corpse was found, and they should have all been turned into quantum ghosts by macro-nuclear fusion weapons.

AA tried to print things to talk to the quantum ghosts, and the sounds, and even most of the radio waves, were impossible for the quantum-scale ghosts to hear.

She needed someone to teach her how to do it, and in physics, she had studied curvature, but she had little exposure to quantum mechanics.
