After the professor disappeared, Siji did not think about his own affairs anymore. Since even the professors and the others were confused, it would be useless to think about it here. He believed that the answer to the mystery will definitely be revealed in the near future. All he had to do was to improve his strength and be prepared to face it.

Just like when the professor appeared, there was no trace of him when he disappeared. If he had not seen it directly, he would have to at least this level if he wanted to fight against those unknown beings.

"I heard that the professor is stronger than Lord Vivika, but I don't know how he is compared to the president."

Arisu muttered as he looked at the professor's disappearance.

"I'm afraid no one knows that he has never fought. After all, they are all strong people in the core circle."

This is not the first time Xia Xu has met a strong man of this level, but even if her strength has improved, she still cannot tell the other party's level.

"I was really shocked. The president actually came here in person. This is a strong man in the core circle."

Mixue, who is already completely familiar with the world of relay, is no longer the novice of the past, and of course understands the meaning represented by the other party.

"Is that true? Hasn't Miyuki seen other interferers in the core circle?"

Siji could not understand the reason why Miyuki was surprised.

“Is there any?”

"Yes, Mixue has seen Vivika?"

"Hmm...oh? Is she that strong?"

Seeing Miyuki so surprised, she seemed to have no idea at all. Siji looked at Natsuo and Arisu.

"Um~~~ I don't seem to have said it. But it wouldn't be unnatural when Miyuki-chan faces Lord Vivika like this, isn't it very good?"

Xia Xu showed a satisfied expression.

"You want me to make a fool of myself!"

Mixue seems to be able to see Xia Xu's routine.

"What is the level of the core circle? My concept of the inner circle is vague."

"It's really time to tell you these."

In fact, Siji originally planned to find time to tell everyone about this, especially Chu Ying, Qiu Hua and Mei Xue are not far from the inner circle.

"I remember I told Miyuki and Chuying about the difference between the inner circle and the middle circle before?"

"Self-circulation system!"

Chu Ying immediately answered.

"Yes. In addition to the accumulation of strength, the outer ring, the middle ring, the inner ring and the core ring are also a person improvement."

Because there is Anna and Mikoto who have recently become an interferor, the four seasons will explain it in detail again.

"I have said before that the outer circle to the middle circle is a breakthrough in the concept of the individual and the rise to the influence of society and civilization, and this is one of the definition methods. When the definition method is aimed at the level of the living body itself, it is manifested as adaptability. To give the simplest example, the physical laws and world laws in different worlds are different, big or small. We interferers can enter various worlds without being affected because of the protection of the system. If ordinary people directly pass through the body, it will be difficult for them to exist. However, although they may be severely damaged or even lose their strength after reaching the middle circle, they can survive in a world where the laws are not very different."

"This adaptability to the law is also proof of reaching the middle circle."

Ramsey, who had always been a teacher next to him, then followed up with the conversation.

"When this response to physical laws and world laws reaches a higher level, it means breaking through from the middle circle to the inner circle. A relatively complete rule system is built, forming a self-consistent structure, so that it completes its own cycle. This system is called the simulated universe, and some people call it the small world, the kingdom of gods, the fairy world, the subspace, the small universe, etc. In short, it is a system that can cycle by itself. After reaching this level, it can open up a world of its own in the current world. As long as it can withstand the correction of the original laws, it will not be damaged or lose its power."

"This self-circulation system is roughly divided into two forms."

Xia Xu, who also reached the inner circle, couldn't help but explain it.

"One is to go outward and build a world of oneself. As Ramsey said just now, it is similar to the Kingdom of God, perhaps a continental form with a round sky, or a galaxy form of the sun, moon and stars, in short, it is a simulated universe model. The other is to go inward, making oneself eternal and unchanging, uninvasive of all laws, and not affected by external objects. This is more common in warriors and treat themselves as a small universe. But ultimately it is to innate one's own laws and form a self-consistent system, and not corrected by the laws of the world."

"If the rules mentioned above are inherently upgraded, it means breaking through to the core circle."

All seasons go back to the question Miyuki asked in the first time.

"It is about to simulate the universe and turn itself into the original singularity. The so-called strong man in the core circle is the universe itself."

Maybe it was digesting the explanations of the four seasons, and no one spoke for a while.

"Of course, what is mentioned above is only for the person of life. For example, some great philosophers and great thinkers have realized the level of the way of heaven entering the inner circle just by thinking, but because of the power of the world they are in, they are like ordinary people."

Siji nodded at the expression "can't be like this" that Mixue and others appeared.

"Well. This will not happen only when it reaches the core circle. At that time, thought itself is a kind of power."

In order to prevent them from becoming more and more chaotic, the four seasons will no longer explain in detail.

"Actually, everyone just needs to have a concept, and there is no need to worry about how they want to develop such things. They will naturally know at that time."

"You're talking about yourself?"

Mixue showed an unacceptable expression.

"It seems we have to work hard."

Even after hearing those words, Qiu Hua's attitude was no different from usual.

"Qu Ying will work hard!"

Chu Ying responded positively.

"The inner circle always feels that it is quite a distant thing."

"Don't be discouraged, Huangquan."

“…”

"Come on."

Even if the level of the inner circle is relatively far away from Huang Quan and others and the feeling is not so deep, it does not prevent them from being affected.

"Ramsey."

After talking about this, Siji is preparing to continue the original purpose of coming here. Ramsey has just expressed his willingness to take over, and he doesn't need to find anyone else.

"It's a matter of the sovereign world, right? Leave it to me and come with me."

After saying that, Ramsey strides towards the teleportation point.

The group followed Ramsey, and they were not going to the inside of the headquarters, but outside of Space City.

"What is the sovereign world you are talking about? You can talk about it now?"

Mixue on the road said that most people who were not sure of it asked.
