Dragon Ball, while crossing the heavens and the world

In weapons class, Kuniji Aoi finally had a chance to teach Oga a lesson openly.

Weapons class requires two people to practice in pairs, so Kunieda Aoi formed a team with Oga without hesitation.

……

"What's wrong? Oga, the leader of the Hundred Demons, can't even beat a girl?" Kuniji Aoi pointed the wooden sword at Oga Tatsumi, who was half kneeling on the ground, and laughed proudly.

"What a hateful woman." Oga wiped the blood from the corner of his mouth and threw away the wooden knife in his hand.

"Hey, what's your name, teacher? There shouldn't be a rule in weapons class that everyone has to use wooden swords to fight, right?"

Rong Qishi shook his head: "This student, you can choose any weapon you want, Desperate Situation Classroom can provide it."

"The light wooden sword is too awkward." Oga showed a wicked smile: "By the way, just use that weapon!"

Oga received the authorization from Nanami, and stamped his feet on the floor. Immediately, a magnetic fluid robot rose from the floor and combined into a... mace.

Bang!

Oga banged his mace on the floor, making a loud metal clang sound.

"Yes, I'm very satisfied with this weight." Oga fought with Kunieda Aoi again amid the cheers from Bell.

Then 10 minutes later, Oga... rushed to the street.

Oga didn't know how to use a mace at all. He sprained his arm by swinging the huge mace, and was knocked down by Kunieda Aoi after seeing the flaw.

The other boys are similar. Heiwajima Shizuo, Hayashida Megumi, Yusuke, etc. are not used to using weapons.

They are better at hand-to-hand combat.

On the contrary, the girls are far more talented in learning swords than the boys. With the guidance of Rong Qishi, their strength has improved rapidly.

If the fighting class in the morning was about the boys stealing the show, then the weapons class in the afternoon was about the girls.

The cold weapon classroom is full of competition.

The thermal weapons class was much more harmonious. The T-800 transformed many weapons. The first class only taught students to understand the structure of weapons, disassemble and assemble weapons, and there was no live ammunition shooting, so it seemed very peaceful.

The afternoon slipped away quietly.

At 04:30, the class is over.

Luo Yan will not take elective courses until seven o'clock in the evening.

There are four elective courses, namely the structure of the world (geography), the distribution of monsters (biology), the secrets of the world (history), and the detailed explanation of martial arts.

Luo Yan only teaches one class every night during self-study. From Sunday to Thursday, that is, from Monday to Thursday, he will take an elective class every night.

Each student must enroll in at least one elective course, or all.

Elective courses are not only taken by the Gotham class, but also by the entire school of [-] students.

Tonight is Luo Yan's first elective class, which talks about the structure of the world.

A total of [-] students have signed up for this course tonight.

As the elite of the Gotham class, the class teacher naturally wanted to cheer for the first class, so all 100 people were present.

At seven o'clock, they arrived at the auditorium on time, waiting for Luo Yan to start class.

The tens of thousands of chairs in the auditorium were almost full of people. Tens of thousands of bad guys were whispering to each other. Although they shouted and cursed, very few people took action.

During the day, all the students saw the terrible side of the teacher in this school.

Everyone in the Gotham class was seriously injured by Luo Yan in the fighting class and had to recuperate in the resurrection water.

The students in Fuyuki's class were all mentally pulled into Sachiko Shinozaki's realm and experienced extreme mental intimidation.

Students in other classes also had their own horrific experiences.

They already understand that this school is different. Every teacher is a formidable and powerful person who needs to be respected. Disobeying teachers casually will only bring misfortune to themselves.

That's why all the students in such a large auditorium with tens of thousands of people were so restrained.

Of course, another important reason is that they have received brutal physical training during the day. Their backs and legs are already sore and their legs are shaking when they walk. How can they still have the energy to fight?

The students in the other six classes are not physical monsters like Oga and Yusuke. Without magic and spiritual power, their physical fitness is worse than Mihashi. After a day of training, it is already a miracle that they can still move around.

When Luo Yan stood on the podium, all the students in the auditorium stood up. The scene was quite spectacular.

Luo Yan raised his hand and pressed it softly to signal the students to sit down, and then entered the lecture mode without any nonsense.

"I am very happy that so many students have taken the course 'The Structure of the World'. Before the course starts, I would like to briefly tell you what this course is about."

Luo Yan looked at the classmates below, randomly named a person and said: "Lion King, what is your understanding of the world, and what do you think the world is made of?"

The Lion King who was named stood up, thought for a while and said: "Teacher, the world is just a food chain or pyramid of layers of oppression. What makes up the world are the corrupt upper ones who need to be destroyed, and the lower ones who are enslaved... "

"Well, Mr. Lion King, the teacher is not discussing political and philosophical issues with you now." Luo Yan said speechlessly: "You can just describe the structure of the world on the material level."

Because of what happened to his sister, Lion King is full of hatred for the existing vested interests that control many resources, and his opinions are mixed with too many personal thoughts.

Luo Yan was not here to discuss social politics today, so he asked Lion King Si to stop speaking and reorganize his words.

The Lion King also seemed to feel that he had said something wrong on this occasion, and changed his words: "The so-called world is the third planet in the solar system under our feet, which is composed of the atmosphere, hydrosphere, biosphere, lithosphere, and many forms of life. The miracle..."

"Okay, please sit down! Lion King Tsukasa-kun."

Luo Yan really chose the wrong spokesperson and directly stopped the Lion King Division from talking.

He stopped asking students to speak, and simply stated his conclusion: "In fact, from a modern scientific point of view, the world is the earth under our feet, and there is nothing wrong with this...

But from a mystical perspective, in addition to the earth where humans live, which is the human world, the entire world also contains many extradimensional spaces, such as the spiritual world, the demon world, the abyss, the mirror world, the digital world and other spaces. "

There were whispers under the podium. When they heard Luo Yan's speech, these students thought that Luo Yan was joking with them and telling them stories.

Many students who have not been exposed to supernatural powers, such as students in Mihua Class, Los Santos Class, and Raccoon Class, do not believe Luo Yan's words.

The students in the Fuyuki class have seen Sachiko Shinozaki's field, and the students in the Amamiya class have seen Yamabuki Otome show her true form as the Hagoromo Fox. There are many students in the Gotham class who have mastered supernatural powers.

Therefore, these three classes can accept Luo Yan's conclusion.

For example, Yusuke knew that what Luo Yan said was absolutely correct. He himself had personal contact with people from the spirit world and the demon world.

Luo Yan ignored the doubts of the students in the audience and continued his explanation: "I don't need to say more about the human world. In today's class, I will mainly explain other worlds to you in general."

"The first is the spiritual world. The so-called spiritual world refers specifically to the world where souls live, which is the underworld, underworld and underworld in various myths. After everyone dies, the soul will go to the spiritual world to wait for reincarnation."

"The spiritual world is vast and boundless. Each region has a corresponding Yama and Pluto. Each region is only responsible for the reincarnation business of its own area of ​​​​the human world."

"The spiritual world is the plane closest to the human world. The space between the two worlds is very thin. At certain times, people and souls can even travel between the two sides at will, such as during the Bon Festival."

"Besides the spiritual world, another material dimension far away from the human world is the demon world, which is also hell."

"The demon world allows both spiritual bodies and flesh and blood bodies to exist in this space. Therefore, in the demon world, there are evil spirits and monsters. It is a zone of energy chaos, filled with countless violent and difficult-to-absorb energy..."

"The biggest difference between the demon world and the spirit world is that the demon world cannot reincarnate spirit bodies. The souls of the demon world can only suffer in the demon world (hell) forever."

"There are also many rulers in the demon world. In addition to the demon kings of the Seven Deadly Sins, there are many existences that are not inferior to them in strength, such as Bo Xun, Luo Hu, Chi You, Lei Chan and other mythical and non-mythical figures."

"Although the demon world is a material world, its rules are very different from those of the human world. When creatures from the demon world come to the human world, they will be greatly restrained and their strength will be greatly reduced."

"Generally speaking, the more powerful a monster is, the harder it is for it to come to the human world. Except for those monsters that have special talents or rely on sacrifices to come to the human world, their strength will not drop significantly. There are almost no exceptions for monsters."

Luo Yan talked eloquently to the students below. Although those students only thought Luo Yan was telling stories, they gradually became fascinated.
