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

The apartment building looked the same as always, with 10 vertical corridors leading to the end, and two rows of rooms that were completely identical except for the door numbers, as neat as a morgue.

The white lights overhead filled the entire corridor, and the air was filled with the familiar scent of air freshener.

Shark Baby covered his nose: "Does all human poop smell like this?"

"This is air freshener!"

"Sorry, I thought this was the smell right next to the toilet."

Li Ji strode forward: "Please follow me, tourists. Today we're going to visit the former residence of the wanted criminal Li Ji!"

The three of them went up to the fourth floor, and as soon as they got off the elevator, they could see yellow and black lights flashing in the corridor.

It was an electronic seal, placed across the doorway of room 405.

A camera was installed on the door, and its red beam almost covered half of the corridor.

"The corridor is narrow and there are security cameras. How are we going to get through?"

Delulu pulled a fluffy golden hamster out of her pocket and started scratching her face.

"what is this?"

"A hamster robot that can share visual perception."

She put the hamster on the ground, and the hamster ran straight towards the door of room 405.

While waiting, Li Ji continued to study the black box.

Based on previous reasoning, the atomic structure diagram represents the number "62" of fundamental particles in the universe, and the one-eyed man represents the history of the one-eyed ruling family's rule over the planet Barbaradu for "44878.93" years.

According to the original owner's habits, the number of years would be accurate to two decimal places, that is, calculated in days.

What do the remaining cockroaches, rockets, and robots mean?
The file mentions cockroaches, and the number of cockroaches in the experiment was "48".

Does "rocket" refer to the number of rockets you've built since you were a child?
That's "4.5". The first launch failed, so it can only be counted as half a launch.

The same applies to robots, which is represented by "17".

With the numbers basically determined, the remaining question is what the four colors represent in terms of operational rules.

No clue at all.

Am I not the one who set the questions? Why can't I understand this at all?

Li Ji, Li Ji, why did you make this piece of junk?
Why would you give Li Keliu something like this?

You can't just be swearing because you can't solve a puzzle, right?
It's not impossible.

Li Ji suddenly realized that both the atomic diagram and the one-eyed man seemed to be things that Li Ke had used to mock him.

Does that mean that all the icons here are related to Li Ke?

It's impossible for Li Ke to know how many rockets he made. Since the original owner gave Li Ke the little black box, he must have given Li Ke a chance to figure out the answer, otherwise it would not be in line with the principle of fair confrontation between the two of them for a long time.

Following this line of reasoning, the number of cockroaches should be four and two-thirds.

The original owner of this body once bought a set of cockroach figurines, but as soon as she entered the convenience store, she dropped one of them, and the cockroach's head was smashed and disappeared.

Unaware of the truth, Li Ke picked up the cockroach head and thought it was real. He was terrified and ran to the police station to confess that he had found a third of a cockroach.

Following this line of reasoning, the rocket number should be 1633454.

When the original owner was 16 years old, he aspired to build a rocket. Li Ke mocked him, saying that even if he were given 1633454 years, he still wouldn't be able to build one.

The original owner remembered the number so clearly that the other party had just made up off the top of their head. There was no need to recall it carefully; the number was as clear in her mind as her birthday.

The original owner of this body was just as vengeful as Nini.

The robot is the natural constant e.

The two were playing a board game, and Li Ji always lost. So he made a robot to train with, but it still lost. Finally, he simply let the robot compete against Li Ji, and that's when it won. The robot's code name was "e".

As for color, that refers to race.

The original owner of this body once proposed a game: standing at the doorway and watching people, with different colors representing different races and arithmetic symbols. The number of eyes and tentacles were calculated using these symbols, and the winner was the fastest. Li Ke said it was a game only idiots would play and refused to play with the original owner, a grudge he still holds to this day.

Looking back, Li Ji realized how important Li Ke was in his life. This wasn't a mystery; it was clearly a love letter to Li Ke!

"It feels disgusting."

"Could the original owner really have a crush on him? But she just deleted the relevant memories, so I don't know?"

Without time to think too much, Li Ji quickly calculated and entered the result.

The box opened with a "click".

Dailulu and Shark quickly surrounded them.

What's inside, meow?

Delulu peeked inside, saw what was inside, and let out a scream: "Danger, meow!"

Li Ji quickly threw away the box, and a cockroach crawled out of it.

The cockroach made a strange sound: "Nissimanam."

"What do you mean? Is that how cockroaches make that sound?"

Shark Baby tugged at Li Ji's tentacle: "Step back a little, or you might accidentally go down the path of crime."

“I’ve been on the path of crime for a long time.”

"Then don't go further down this path."

Lee Ki reached out and tried to touch the cockroach.

Suddenly, the cockroach flapped its wings and took flight, startling everyone into retreating.

The cockroach flew along the corridor, quickly passing through the area blocked by the cameras. The three of them slammed on the brakes and almost got caught on camera.

"There's definitely something wrong with this thing. What if we can't get through?"

Watching the cockroach fly further and further away, Delulu said, "Let my little hamster chase after the cat! Anyway, you can't open the door, so we can't let it come for nothing!"

The little hamster suddenly stood up, and blue flames shot out from the center of its paws, flying towards the cockroach and quickly disappearing at the end of the corridor.

Delulu squinted one eye: "Come with me, meow!"

The three quickly went downstairs, exited the convenience store through the underground passage, and walked along the street.

Looking at the familiar street, Li Ji immediately realized, "This is the road out of the city!"

The three of them left the city and walked along the road toward the distant green mountains.

The Ueno Road and the mountain path were completely unpaved, relying entirely on the shark to clear the way.

Shark Baby's mouth is like a lawnmower; it can chew up any weeds, thorns, or even man-eating flowers.

Li Ji and Dai Lulu were panting heavily: "Is this supposed to be a search for clues, or a wilderness training exercise, meow?"

Green scum kept spitting out of Shark Baby's mouth: "Is this a search for clues or a picnic?"

They arrived at the cave halfway up the mountain. The cave was pitch black inside, and they couldn't see anything.

"A cockroach went in, meow."

Shark let out a burp: "Burp~" The sound made both of their eyelids sway.

"Is it possible that the cockroach simply ran away without any other intention?"

"Impossible. You just heard it, the cockroach made a strange noise. The file records that I used cockroaches in experiments, and one of them could meow like a cat. Maybe this cockroach is the same, it's a test subject."

"Then let's go inside, meow."

As the three were about to go inside, they heard strange noises coming from within.

"Coo coo~ Coo~ Coo coo coo~" (End of this chapter)
