When Chu Feng carefully observed the array here, his expression gradually became strange.

When he got the mysterious ancient books in his previous life, he once lamented that the vast amount of knowledge in the mysterious ancient books was because there were too many things recorded on them, so he just chose a suitable study.

But in the selection time, or the whole content of the book are rough browsing.

Among them, there seems to be such a strange eight trigrams array recorded in the array.

Because the learning difficulty of the array is too high, Chu Feng didn't learn too much. He just learned the knowledge about the border, that is, the energy shield.

Later, because of the need of the situation, he learned the seal array.

For this special kind of chicken ribs array, because the difficulty is too high, so he gave up, his energy is limited, more willing to use to improve their strength.

Chu Feng thought to himself: "although it seems to be different from the impression, there is no doubt that it is the same series of arrays. Was it the last owner of the mysterious ancient books who came here, or did you say that all the arrays will return to the same direction when they develop to a certain extent?"

I don't know why, but I'm not going to ask.

There are too many contents in the mysterious ancient books. Even if he wants to impart them to others, it must be under his control.

If the previous owner of the mysterious ancient book really has a certain connection with this place, and the other party deduces something from the clues in his own words, the consequences may be great.

Maybe both sides were not enemies originally, and they will become enemies as a result.

Chu Feng is never afraid of making enemies, but there is no need to increase them. After all, it's easy to protect himself, but it's hard to protect the people around him.

This is a strange array. There is only one use, that is, to save important things.

If there is anything important in the future, it must be used on the spot, or as far as possible to dig out the usage, where someone would be so stupid to save it, so Chu Feng refused to learn.

The eight directions of the eight trigrams array are actually eight keys.

Every time a key is put in, the door lock will be weakened by one point to a certain extent. Even if all the "keys" are not gathered, the array can be forcibly opened.

Chu Feng thought about it, then took out a flag and put it into a groove.

After putting a flag in, Chu Feng felt that the array was weakened, but at the same time, a message came into his mind.

Heaven and earth! 】

although there are only a few simple words, Chu Feng still reads out some inexplicable meanings. This heaven and earth is not the real heaven and earth, but refers to heaven and earth.

That is the complete version of Xuantian seal.

When these words appear in his mind, Chu Feng feels that his soul seems to have an invisible mark, and appears in his soul silently.

Because of the existence of this seal, when you meet the holder of the seal of heaven and earth, you must obey the other party's orders, or you will be backfired.

Of course, it seems that the degree of this kind of backfire is not very great. It's just like that ministers should obey the king's orders and do some small actions in the corner where the king can't see.

"No wonder those people try their best to take the Xuantian seal from me, but they are not willing to use their strength to take it. It's because they are limited."

When feeling this imprint, Chu Feng also understood some things.

However, even if xuantianyin was in his own hands now, Chu Feng did not want to be restricted by this kind of shackles.

"Refining!"

In the operation of the unknown skill, this mark was quickly refined into the purest spirit and the power of rules, and disappeared in his own soul, as if it had never appeared.

This is also Chu Feng's courage to try.

Then Chu Feng put in the spear, machete and dagger, and the seal of the eight trigrams array was weakened in half.

Every time he put in a weapon, Chu Feng felt that there was a soul shackle imposed on his soul, but Chu Feng easily refined these soul shackles.

In front of the unknown method, everything must return to the essence.

When the seal here was half removed, Chu Feng did not continue to place these treasures, but directly extended his hand to the middle of the seal.

The power of earth, water, fire and wind condenses in Chu Feng's hand, and then reaches a delicate balance. A space ripple appears, and Chu Feng's hand reaches directly into the middle of the eight trigrams array.

The complete Qimen Bagua array has the effect of confining the forbidden space. It is the four treasures that Chu Feng just placed. They represent the four directions of Kun, Kan, Xun and Li, that is, the earth, water, wind and fire. This makes the spatial layout of this Qimen array lose its foundation and the effect of resisting space.

This is also the reason why Chu Feng deliberately did it in order to confirm the relationship between this array and the mysterious ancient books. Otherwise, he would prefer to use force to break the art.Because Qimen array has some explanations on earth, it's not surprising that he knows this.

After the space ripples flashed, Chu Feng had a small seal the size of a palm in his hand, and then Chu Feng took the seal into the yuan house.

He didn't know what kind of changes would happen when the former Xuantian seal and the mountain seal were combined, but for the sake of safety, he preferred to put them in the yuan palace, so that the changes were controllable.

After taking out the seal, Chu Feng also confirmed one thing.

The layout here is really related to the way of array in the mysterious ancient books.

Just as Chu Feng was about to turn around and leave, the mysterious voice suddenly said, "I'd like to exchange one thing for a promise. I don't know if you want to."

"It depends on whether what you give is in line with my mind." Chu Feng said calmly.

If what the other party gives himself is really valuable, he doesn't mind giving a promise.

Although he is not the kind of person who sticks to his promise, as long as the interests are big enough, it is nothing to let him give up his promise, but his position here, his promise also has high value.

If the other party is clever, he has no reason to destroy it.

He was hostile to Shuifu because the other side was too arrogant.

Chu Feng is a staunch racist. In his eyes, it is above the human race. Although he knows that this idea is not conducive to the development of the whole human race, he is not willing to change it.

Anyway, he is not interested in being the master of the human race. As long as the racist is not in a high position, sometimes it will be a good thing.

Of course, the real high-ranking racist is a racial disaster.
