() A thick layer of dust has fallen on the door on the second floor, and I don't know how long no one has set foot here.

Su Jiu sacrificed a dust talisman, the talisman took effect, and the layer of ash on the door was instantly cleaned up, revealing the original appearance of the door.

The pattern engraved on the door on the second floor is like an ancient totem, and judging from the material and age of this door, it does not look like a product of the millennium of the Cang realm, but it is similar to the mural on the outer wall.

Su Jiu always felt that this totem was familiar, as if he had seen it somewhere.

"Senior sister?"

Xia Jue's reminder pulled Su Jiu's thoughts back. Only then did he realize that he had been staring at the totem on the door for a long time.

"Su Daoyou is fine. Lan Ziyi looked at her expression, and it didn't seem to have changed.

Su Jiu smiled, slowly pushed open the door in front of him, and what appeared in front of him was a library.

These bookshelves are placed in eight different directions, of which there are exactly twenty-four bookshelves.

In the middle of these bookshelves is a small platform that is not very high, with three steps from the bottom to the top, and in the center of the small platform is the pattern of a yin and yang fish.

In addition, the walls around the perimeter are wide, and the walls above the head show a huge star map.

As soon as Su Jiu pushed the door open, the people who followed him rushed up.

Probably because of the previous lesson, neither the casual cultivators nor the sect disciples were in too much of a hurry to explore this not very large space.

Xia Jue didn't know what to think of, smiled, and took the lead in stepping in.

Everyone saw that Xia Jue did not have any abnormalities, so they followed up one after another.

Although Su Jiu doesn't understand the Five Elements Bagua Qimen Dunjia, he has an excellent memory ability for what he has seen.

When I saw the totem above in front of the door, I felt familiar, but now I see the star map on the wall of this room.

Different from Su Jiu's doubts, when Lan Ziyi saw the star map of this space, he directly stood in place.

This star map is in the Heavenly Machine Sect, and ordinary disciples have never seen it, but he has seen it.

The star map on this stone wall is compared with the star map brought out by Yun Huanling from the cold of the night, although the position of the natal star is different alone, but the trajectory of many natal stars on it is the same.

Obviously, the star map that Yun Huanling handed over to the sect had a much earlier trajectory, and what he saw now was a little later than the star map in the sect.

But no matter which of these two star charts they are, there is a world of difference between them and the life star orbit running in the sky of the Cang Realm today.

Lan Ziyi even suspected that these two alien star maps were not star maps of the Cang Realm, but he couldn't explain where this star map came from.

While pondering the various special features of this, he carved the star map part of this secret room into the jade slip.

Although the little disciple who followed behind Lan Ziyi was still shallow, he also saw the problems in the star map of this secret room.

After all, the people who can be brought out by Lan Ziyi are enough to prove that their talent is extraordinary.

"Huh, this star map is so strange, according to this star chart, shouldn't that era be a prosperous era when flowers are in full bloom and stars are shining?"

Lan Ziyi entered the star map into Yu Jian's hand, yes, this star map does not look like the Cang realm, although he doesn't know the past Cang realm, but he also knows that in the past ten thousand years, there has been no star shining in the Cang realm.

Another little disciple said, "It's a pity, this star map is only half, and I can't continue to see the follow-up from that era, as if..."

In the end, it was Lan Ziyi who helped him connect and said, "It seems that this Heavenly Dao deliberately erases what may happen in the future, leaving only this current star map." ”

When he said this, Lan Ziyi's eyes couldn't help but sink slightly, and he tried his best to deny in his heart that this was not the star map of the Cang realm, but his sixth consciousness told him that this was the star map of the Cang realm.

Lan Ziyi's mind is very confused, and he will definitely check the trend of the star map of this Cang Realm ten thousand years ago after he goes back this time.

The little disciple listened to Lan Ziyi's words, and quickly nodded, "Yes, just like the senior brother said, it seems to have been deliberately erased." ”

After everyone entered the door, Su Jiu did not follow in, but still stood at the door with a little thoughtfulness.

She was deaf and clear-sighted, and she also heard the conversation between Lan Ziyi and the little disciples.

She said, how could she feel that this star map is so familiar, it turns out that it is like this, at the same time, Su Jiu also remembered the totem on the door, where had she seen it.

After the Blood Mist Forest was broken, the Phantom Blood Demon died, and the bottom of the blood pool in the cave where she lived, after the blood was sucked dry, revealed the totem exactly like what she had just seen on the door.

Su Jiu can be sure that this white attic has an inevitable connection with the night cold tan, but now she has too little evidence in her hands, so what kind of connection it has, she can't figure it out yet.

Tong Qi seemed to be a little worried about Su Jiu.

"What's the matter? You've been weird since you first walked through the door. ”

Su Jiu shook his head and asked a little absent-mindedly, "Do you know the origin of this Extreme North Secret Realm?"

Tong Qi was stunned for a moment, and said with a wry smile, "Where do I know this, I only know that this secret realm can actually be opened if you want to, but the key is in the hands of the Scattered Cultivation Alliance, but the people of the Scattered Cultivation Alliance don't open this secret realm very much, and even the time to open this secret realm is not as frequent as the cold night." ”

Su Jiu's pupils narrowed slightly, and he always felt that the people in the Scattered Cultivation Alliance seemed to know something.

"Is there a pattern to the time when they open the secret realm?"

Tong Qi thought about the matter of the Extreme North Secret Realm nearly thousands of years ago, and then shook his head, "There is no pattern. ”

At least not every few years.

Could it be that if you want to open it for no reason? Don't talk about Su Jiu, I am afraid that I will not believe it if I change it casually.

She knew there had to be a reason for that.

But what was the specific reason, she thought that she went to the Scattered Cultivation Alliance, and she was afraid that she would also be sent out in a few words, if it was really a secret, they would not easily tell it.

Su Jiu glanced at the Buddha beads in his hand, and said in his heart, as well as the old monk who buried the beads here when the secret realm was opened last time, maybe he would know something.

It's just that the Cang realm is so big, where can she go to find such a monk.

If there are many secrets hidden in the Nightfall, there will be no fewer secrets in this secret realm than in the Nightfall.

At least Su Jiu knew that the night cold Tan was the place where the demon realm invaded and turned into that desolate appearance, and since then she has been isolated from the Cang realm and sealed it with eight secret keys, but in this extreme northern secret realm, she now has no clues.

And the only thing that can have anything to do with the cold of the night is this white attic.

Su Jiu's thoughts were flying, and he couldn't help but think of the Demon Realm descent and the destruction of the Tower of Babel recorded in the book.

With the passage of time, the events of the past have gradually turned into the dust of history, and even such major events as the advent of the Demon Realm and the destruction of the Tower of Babel are only a few quick strokes in the historical record.

Su Jiu felt a little powerless, is it really possible for the secrets that have been buried in this world to be excavated?

And in today's world, how many people are left who really want to excavate?
