He lives on another planet and is majoring in Earth Science.

Nini smiled excitedly, immediately opened the spaceship's engine cover, and began tampering with it without saying a word.

Sitting inside the spaceship, Li Ji took deep breaths, trying to calm his agitated mind and begin to organize his reasoning.

These past few days he's been thinking about how his memories of Earth, which weren't sealed away in his mind, were retrieved.

He kept going around in circles with the ideas of neuroscience, but ignored quantum mechanics.

Currently, there is only one known way to transfer memories from Earth's Liki brain to an alien Liki brain: quantum communication.

Quantum communication can instantly transmit information regardless of distance without any external assistance.

By forming quantum entanglement between the electrons in the neurons storing Earth's memories and the electrons in one's own consciousness, the memories can be directly transmitted.

The consciousness is in a quantum superposition state, like Schrödinger's cat. The existence of memory can only be determined at the moment it is observed.

When the outside world reads his consciousness, the existence of Earth's memories is already determined. If he does not recall those Earth memories at this moment, the outside world will not be able to observe them at that moment.

This is why existing memory reading technologies can only read memory fragments, but it is difficult to read the feelings of the person involved, because human consciousness is also in a quantum state.

In layman's terms, Earth Li Ji and Alien Li Ji have a data cable installed in their brains. The data cable is connected to a disk containing Earth's memories. He can read this disk at any time, and if he doesn't read it, no one else has permission to read it.

When the outside world enters his mind, it can only read the memories sealed within his mind. The data cable only appears when Li Ji wants to connect, so the outside world cannot access those Earth memories.

This leads to a chilling question.

Quantum communication is bidirectional; if one can access another's memories, the other can also access one's own.

My own time travel might be related to this.

I can't quite figure out the principle yet, but it seems somewhat similar to the quantum mosquito experiment. I'll have to ask the big mosquito when I get out.

Perhaps the original owner of this body is currently using it to wreak havoc on Earth.

"Looks like I'll be busy once I get out here."

Li Ji quickly listed the tasks he would be tasked with after leaving the camp.

First, we must find evidence of our time travel. The original owner must have achieved a consciousness swap through some kind of experiment, presumably related to the cat-calling-cockroach incident. The destruction of the experimental equipment must have left clues, which we can look for by following the missing fragments of memory.

Secondly, the original body must be found and switched back. Earthlings are considered primitive and therefore not considered human in the Interstellar Alliance, thus having no obligation to obey the law. Without switching back the body, the original body cannot be brought to justice.

Otherwise, it would be necessary to challenge the existing judicial system of the alliance and let judges determine whether the perpetrator of a crime is a physical body or a consciousness.

Before the curfew that night, Li Ji came to the phone booth again.

He dialed Shark's number.

"Shark, transfer me to Dailulu."

A familiar, sweet voice came from the other end of the phone: "What do you want, meow?"

Li Ji chuckled: "How come you have Shark Baby's communicator?"

"Let's meow together."

A noisy commotion came from the other end of the phone, with men, women, and children arguing and shouting things like "cannon," "gun," and "spaceship."

"It's so noisy over there, where are you?"

"Wait a minute at Milia's house, I'm going to find another place, wait a minute meow."

Dailu covered the phone and wiped the engine oil off her face.

She was lying on an old-fashioned spaceship, its roof covered with various cannons, like a machine gunner.

Several slime uncles were busy running around on the spaceship.

"Second Uncle, how do I get down here, meow?" Without saying a word, Second Uncle Slime stretched out his arms, forming a sloping bridge connecting to the ground.

"Thank you, Uncle Meow!"

Delulu slid down her second uncle's arm and asked Milia to take her to a secluded place.

Milia, her eyes sparkling, linked arms with Delulu's: "Li Ji called?"

Dailu nodded: "Hurry up, he doesn't have much time. I heard that in prison, each person can only make one phone call a day at most, meow."

The two quickly went into the metal hut, where the soundproofing was excellent and the noise outside could not be heard at all.

Dailu picked up the phone again: "Li Ji, are you alright, meow?"

"I'm fine. I've gotten used to being here and am prepared to stay for a long time. It's just a pity that I'll miss your birthday."

Delulu understood immediately. Her birthday had long passed, and this was clearly Li Ji's signal to confirm the time for the prison break.

She said playfully, "Then call me on my birthday. You didn't forget my birthday, meow? Tomorrow, meow. When are you going to call me, meow?"

"I can only call you at night. If I had a choice, I would call you at 2 p.m. if I could."

Li Ji has not yet come up with a plan to escape at night; his current option is to create a disturbance during the afternoon working hours and then flee.

Dailulu said with a grin, "Then you'd better think of a way, meow! I'm going to celebrate with my friends tonight, everything's all set up. If you call at 2 pm, we can chat for a long time, meow."

"I'll go ask the warden."

Dailulu feigned a coquettish resentment, saying, "What do you mean 'ask' meow? I need you to confirm it meow! Two o'clock is two o'clock meow. If you call me tonight, I won't answer meow!"

How can you be so unreasonable?

"Is this the first day you've met me, meow?"

"Okay, okay, I'll try my best."

"You must call me on time, meow. I'll be waiting by the phone from noon onwards. I'll be very sad if I don't hear your voice, meow."

Dai Lulu's delicate tone made Li Ji's heart tremble. He didn't know if it was a coded message or a genuine expression of emotion.

"I will."

Delulu gripped the communicator tightly and shouted, "I miss you so much, meow!"

Li Ji was taken aback; this didn't seem to be a code.

He hesitated before saying, "I miss you too."

"Let's talk again on my birthday, meow."

"it is good."

After the call ended, both of their hearts pounded for a long time.

The prison guard, who was eavesdropping on the call, smiled like an aunt: "Such pure emotions. It's been a long time since I've felt this comfortable while eavesdropping. Compared to those guys who have sex over the phone, they're a breath of fresh air."

Milia, standing next to her, watched with hearts in her eyes, her face burning with excitement.

Shark Baby ran straight out, muttering to herself, "It's the class monitor's birthday, what gift should I give him? This is so troublesome. I also need to prepare one for Li Ji. Li Ji will definitely thank me."

Shark bumped into a four-eyed toad dressed in military uniform, and the two apologized to each other.

The four-eyed toad asked, "Where is Miss Delulu?"

Shark Baby pointed to the room: "She's inside." (End of Chapter)
