Usually, I treat the disease, but what do I do in my spare time?

Sleep? No, the great Comrade Gao Sen team may spend his precious time on sleeping. Of course, he is looking for some of these free laborers that he needs very much.

Rules and layout diagrams of magic circles.

This kind of thing exists in the human world, but there is no very useful magic array. For Gao Sen, those who cannot kill a dragon all at once are small magic arrays. The dragon clan has existed in this world for so many years, and it also claims to be the most noble and wise race in the world. Then they cannot easily dig a cave like a primitive tribe like what ordinary people think, and then use two taels of gold to pave the dragon cave in the city. That is impossible.

They must have an extremely developed civilization, and what they showed in front of Gao Sen should be just what they did for Gao Sen to see, which is simply unreliable. Their real world should still be in a certain corner, as if they were saying, and above their heads is a huge dragon soul barrier used to isolate external terrifying forces.

Just imagine, who would set up his home on a very dangerous frontline? Humans don’t know, and dragons are so smart, probably they don’t know, so the reason is that these things are for Gao Sen to see.

When Gao Sen proposed to learn about the rules and composition rules of magic circles, Elder Jinlong did not immediately express it and showed unprecedented difficulties.

A bunch of dragon elders discussed together for a long time, but in the end they decided to agree to Gao Sen's request.

However, they also have a condition, which is to require Gao Sen to teach the dragon clan the technique of portraying the magic array on the body when it is convenient, and to make a contract, and not use the techniques he learned to deal with the dragon clan. Gao Sen naturally agreed to this condition without any hesitation.

Some Dragon Clan elders expressed varying degrees of concern about Gao Sen's promise so happily, but since Gao Sen had agreed to them, there was nothing to say.

Then Gao Sen left Long Peak under the leadership of an elder. Of course, this time Gao Sen did not enjoy the enjoyment of the bureau-level sitting on the dragon's back. Instead, he followed the dragon elder all the way to a small forest in the distance, where there was a very inconspicuous black stone.

"Please come in." The elder made a gesture of asking for help, but Gao Sen did not move because his gesture pointed to the stone, and Gao Sen did not move. Who knows how that thing was used? Is it to be activated? Or should it be moved away? Or is it just the knowledge itself? You must understand these things. If you don't understand, you will be laughed at by others.

"You'd better ask first, after all, you're an elder." Gao Sen was very polite.

The elder who brought Gao Sen over looked strange. When did he become a human elder? After all, he is not of the same clan. There is no seniority to be said. However, Gao Sen's rare politeness still made the elder not think of more, so he nodded and walked directly into the stone.

Gao Sen sweated coldly. His own detection equipment always thought that this thing was a stone, but he didn't expect that this thing could actually be entered. It seemed that this thing was just a door.

When Gao Sen saw the other party enter, he carefully tried to touch the surface of the stone. Sure enough, this surface was the same as if it did not exist. Without any obstacles, Gao Sen's hand reached in. Since he knew that this thing was fake, Gao Sen had nothing to worry about, so he walked in directly.

What appeared in front of Gao Sen was a hey corridor. Gao Sen felt that even his own night vision equipment could not work well in this corridor. He could only see a rough outline like the boundary on all sides, and there was nothing else, and only the position of the Dragon Clan Elder was brighter.

Seeing the elder looking at him, Gao Sen quickly stepped over.

"This is the only way to enter our Dragon Clan Knowledge Hall, and it is a corridor of wisdom. After this, you must go through the test of wisdom, otherwise even we cannot come in casually." The elder explained to Gao Sen.

"I have to wait for the test when entering a library?" Gao Sen looked disbelieving.

"This is not a library, young man." The elder explained to Gao Sen.

"The place you are about to enter is the Hall of Knowledge, an entity of thinking and consciousness composed of millions of immortal souls of the dragon clan. Since he inherited almost all the knowledge of the dragon clan for millions of years, he is said to be omniscient. However, since he is a ** consciousness body, he also has his own personality, hobbies, likes and dislikes. Therefore, he also has his own regulations on the teaching of knowledge."

"Is this person who wants to enter the temple going through his test?"

"That's right, that great existence believes that some lives have no meaning even if they have acquired knowledge, because they don't know how to truly use the knowledge they have obtained. Some lives can carry forward this knowledge as long as they have obtained a little knowledge and make him more knowledge. Therefore, only when he thinks there is a necessary life, he will truly tell him the knowledge." The elder explained to Gao Sen in detail.

"Since that's the case, let's go and see what kind of existence this powerful man who is said to be omniscient." Gao Sen shook his head indifferently.

Gao Sen always believed that this was a conspiracy discussed by the Dragon Clan. They didn't want to give themselves what they wanted, but they couldn't confront themselves head-on. So they simply let themselves come to this strange person to hit the nail. Anyway, they knew that they would definitely not understand what the Dragon Clan was studying every day. As long as they didn't pass this level, they would have no complaints that they were not cooperating, and they didn't have to give their things.

Therefore, these dragon clans who call themselves great all day long are fearful of death. In order to save their lives, they gave them so many good things casually, and they were unwilling to tell themselves about some simple magic circles.

In fact, what Gao Sen didn't know was that this kind of thing that Gao Sen thought was simple was the most serious thing in the magic circle.

Over the years, countless magic circle experts have racked their brains to find the composition rules of the magic circle. Some magic circles that have spread in the human world are simply derived from the knowledge of the dragon clan. Humans can only understand the rules of some simple magic circles, but what people don’t know is the basic composition rules of the magic circle.

For countless years, humans have been using simple magic arrays that have been spread all over the world. However, if someone masters the composition rules of the real magic array and with the infinite creative ability of human beings, it is estimated that this world has not been destroyed by alien races, and they may have been destroyed in the hands of human beings.

With all kinds of questions, all kinds of confusion and boredom, Gao Sen finally arrived at the gate of the legendary Hall of Knowledge.

The gate is very simple, without any brilliant golden walls or any very complex decoration, just a simple wood gate.

"When you open the door, there is the temple of knowledge. Here you can think of the great existence to ask all the questions you want to know. But at the beginning, the great existence will ask you questions. Only if your answers satisfy him, you can be qualified to ask questions." The elder explained to Gao Sen.

Gao Sen noticed a word, satisfaction. This word is different from correctness. In other words, the answer to this question may not be correct, but it will definitely satisfy the smartest person in the legend. Gao Sen's scalp was numb. What he was most not good at is using his brain. It's okay to be clever, but this kind of wisdom that is said to be true and real swords and guns. How could he be his opponent?

But since you are here, you must go in!

Men must not be soft at critical moments!

When he opened the door, he welcomed Gao Sen one by one. Then Gao Sen immediately began to adjust his vision, and soon he completed the adaptation to the surrounding light. This light did not come from a certain light or source, but from the entire space around him, and the fluctuation interference of the surrounding light was almost zero, that is to say, almost every molecule around this space is luminous.

"Hello, visitor--" A loud and full voice appeared around Gao Sen.

"Hello, it is said that you know everything... Uh... what should I call you?" Gao Sen carefully asked the voice for his politeness.

"You can call me a dragon, but I am not a dragon. Although I have the knowledge of countless dragons, I am not a dragon. I am a collection of immortal souls after countless dragons' death. I am the dragon soul." The other party's speech speed always maintains an average speed, and there is no fluctuation in the tone at all, just like an old-fashioned sound synthesis system.

"Are you a dragon soul? Then the dragon soul barrier outside is also your work?" Gao Sen showed strong curiosity.

"Yes, there are invaders from other planes on the periphery of the barrier, who are very powerful. Before finding the power to destroy them, I must prevent them from entering our world. Once they come to our world, this world will be immediately infected by their power, then sink, and finally become an eternal death."
