C9 Wall with Ear

The restaurant was numbered 7, which meant, firstly, that this school was really big, and secondly, that there were really a lot of people in this school.

There weren't many people in the dining hall at the moment. Ji Kang thought that the students were too lazy. When he was at school, he had already run five laps around the sports field.

"Little Hua, how old are you this year?" Teacher Chen opened his mouth to speak.

"En, I was picked up by an uncle and brought home. I really can't recall anything about my birth. I'm sorry." Ji Kang randomly asked.

"I see. But you look to be about the same age as the students at school. It's really hard for you to come out to work at such a young age." You don't know, these college students at the age of twenty-four or twenty-five are sometimes really as stupid and annoying as kindergarten kids. "

"So those youngsters are the same age as me," Ji Kang thought to himself.

Teacher Chen finished eating first. She wiped her mouth with a tissue and said, "I'll take care of this little friend of yours. If there's anything you need help with, please contact me. As long as it's something I can help with, I will." This is my contact number, please take it. " She handed over a business card.

Ji Kang still had to continue working. After leaving the restaurant, he bid farewell to Teacher Chen.

When it was eight or nine o'clock, Ji Kang had already diligently cleaned up the entire campus. On the way back, he coincidentally met Officer Chu Yang, who was wearing a police uniform. Are you used to it? When you're not working, you don't have to stay in your room and look at the screen every day. It's also good to come out and get some fresh air. " With that, he waved his hand and quickly walked forward, as if he had something important to do.

Ji Kang was in no hurry to return to the police station. He just leisurely strolled around the campus.

Suddenly, a middle-aged woman entered Ji Kang's sight. Ji Kang recalled that this was the person he met in the park with Huang Fan that day.

The middle-aged woman entered a five story school building. Ji Kang naturally followed behind her. Thinking that she and Huang Fan must have a deep connection, Ji Kang decided to find out her identity.

She entered a classroom on the first floor. It seemed like she was a teacher at this university. Ji Kang pretended as if nothing had happened as he walked through the door, faintly hearing the words "Hello, Professor Plum".

So she was the one who recommended him? Ji Kang walked back out of the building.

At this moment, there was no one outside. Perhaps it was due to the fact that class was still going on, Ji Kang approached the outer wall of the classroom. He squatted down by the front window and attentively listened to the sounds coming from inside.

"Fellow student Chu Feng, please repeat the general contents of our course yesterday morning."

Only a melodious voice could be heard saying, "We learned briefly about wormhole safety yesterday morning, and because of the spatial curvature of the wormhole, there is a great deal of tension when passing through it, so that when the wormhole is less than 100 million light-years in diameter, any hard substance will be torn to pieces. Thus, by constructing a large number of wormholes near the wormhole and building a certain number of wormholes at the entrance to the wormhole to counteract the tension, the entrance of these wormholes is the opposite direction of the target wormhole, but even so, after a short period of time, the offset effect will be immediately reduced to the lowest point, so our spacecraft must travel at over 50% of the speed."

"We have also learned the theory of the N-dimensional universe," the bell-like girl continued. "The Yellow Emperor's ancestor believed that when we pass through the wormhole, we can only reach a time and space later in the same universe. That is to say, we can only travel to the future and not to the past.

"Very good," Professor Plum said. "Student Chu Tu's description is very complete and accurate, so we will continue to study the N Dimensional Universe, N Dimensional Universe, which refers to the past and not the future. To put it simply, we can bring that space-time thing to the present in the future, of course, we need to take it into account when we return to the present space-time, but there is a limit to our stay in the future, which is generally 33 years, because the expansion of the universe is constant, the technical conditions are limited, and the wormhole that we need to construct after 33 years has already exceeded our imagination. Therefore, once we have passed this time limit, we will only be able to live in the future and never return here. "

She continued, "And to travel to the past, we have never implemented it. The Yellow Emperor believed that transmigrating to the past could not change history. If he wanted to change the past, there would be a powerful force field to prevent events from happening. In recent years, however, some cosmologists, such as Professor Gao Yuan at our school, have come to believe that going back to the past can change history. We call it the N-dimensional theory of the universe. "Recently, Professor Gao contacted the Aerospace Center to organize the implementation of this experiment. However, there are still a lot of technical loopholes in the structure that allow one to pass through the wormhole in the past. Professor Gao believes that the spatiotemporal fine pipes that lead to the future are concave, while the fine pipes in the past are convex …"

Ji Kang became more and more interested as he listened, and the next lesson made him feel as if it was a fantasy story.

"Please keep the following information a secret from strangers, or you will be punished by the Chief Justice for violating the code of confidentiality. Our ancestors knew that they were from Earth, in the distant Milky Way, hundreds of thousands of light years away from our fairy galaxy. Actually, the Yellow Emperor was born more than four thousand years ago — more than ten thousand years ago on Earth — but he was conceived on Earth. His mother was captured by the Abbey and taken to Abbey. She was in her sixties by then, and the child in her womb was our ancestor. But instead of killing or mistreating them, the Abigail took care of their lives after a series of not-too-excessive experiments with them. The Yellow Emperor had fully integrated himself into their lives and had learned from them how to travel through time and space. Suddenly one day, a group of terrifying people appeared on Abbey. The Yellow Emperor called them the Ghost Starmen. After understanding the language of the Earth, the Yellow Emperor felt that this phrase couldn't be more appropriate to describe them. "According to the Yellow Emperor's description, these guys are two and a half meters tall, even more ferocious than the barks in our class."

A cheerful laugh came from the classroom.

Professor Plum continued, "These guys have maroon skin, shawls, and yellow aprons. Their bodies were as hard as rocks, impenetrable, and bloodthirsty and brutal. Before Abacus could respond effectively, its inhabitants had been almost completely slaughtered, and it was recorded that the Yellow Emperor still had some lingering fear when he recalled how the Ghost Star Men had ripped open the Abbey's chest and plunged into it to chew its flesh. Fortunately, the Abbey survivors who were with them had reacted in time to flee into the universe, creating wormholes and fleeing awkwardly to an unknown place, where we were. They even brought a certain amount of food with them as they fled. After arriving here, the Yellow Emperor's mother and son clearly felt that the amount of oxygen they had was too little. The Abbey had expected them to help build wormholes and search for dark matter, but the mother and child were dying, so they thought the two of them were a burden and wanted to kill them. At this moment, the Yellow Emperor suddenly exploded. It turned out that the Yellow Emperor had already adapted to the hypoxic environment, and his previous illness was only similar to a cold. "The Yellow Emperor used his own intelligence and stamina that is far stronger than the people of Abbey, and killed them all one by one …"

Ji Kang listened with relish as an hour passed unknowingly. Professor Plum said, "Alright, let's take a break. We'll continue after a quarter of an hour."

Just like this, Ji Kang had nothing to do other than work. When he saw no one around him, he ran to the window to eavesdrop. In the evening, he would record down everything he heard. Through this period of time, Ji Kang learned a lot of information about this planet. For example, the Yellow Emperor used the machines left behind by the Abbey people to prepare to return to Earth, but due to his lack of skill, he didn't adjust the time and place properly. Finally, they arrived at the Southern Song Dynasty on Earth. He did not understand why the white man wanted to slaughter his own kind, so he decided to return to the planet where he had fled to. This time, he studied the information left behind by the Abigail people, made sure that this would not go wrong, and then began to search for a woman who could bear his children, as instructed by his mother, whom he now revered as the Virgin, worshipped by tens of thousands of people, and who, with the patient persuasion of the Yellow Emperor, returned to Earth in the tenth year. Since the creatures brought back from Earth did not adapt to the environment here, and died pretty quickly, and the food consumption was very fast, and the Holy Mother died soon after she returned here, the Yellow Emperor decided to make another trip to his home planet. This time, he went to Earth 10,000 years later, around 111,000 AD, and brought back from there more complete species of species and knowledge about improving the environment here and some apparatus.

One day, Ji Kang, who was listening in on cosmology lessons outside a teaching building, was concentrating on stealing the free knowledge. Suddenly, someone patted his shoulder and gave him a big jump. "It scared me to death."

Huang Fan was standing right in front of him, smiling as he looked at him, "Kid, how was it? Are you used to it? "

"Mm, okay, how did you find me?"

"I drove past here today to visit you, but when I arrived at the police station, the duty officer said that you weren't there. I was about to leave when I met Officer Chu Yang, who told me that you might be hanging around, so I thought I shouldn't come here for nothing. In the end, I found you in just a short while. "

"Then let's go back to my place and have a chat." Ji Kang and Huang Fan walked towards the police station.
