Half a month later.

Clear salt water had begun to flow out of the small holes in the knots of pine and cypress trees, which meant that the Kunlun Plateau and Fenbao Rock outside had been completely submerged by the rising sea level.

This was also expected. After all, the leak in the sky could no longer be repaired at this time. It was only a matter of time before the whole world was submerged by the water of the Milky Way.

Xu Yinglian came to the pine and cypress trees and asked:

"How long will it take for the entire secret realm to be filled with water?"

"Probably more than twenty days." Qiu Changtian replied, "But even if the secret realm is flooded, it will not affect our survival."

"The real threats are the stars and demons outside."

If a star hits your head, you will die. However, if you are in a place with good visibility, you can effectively avoid it in advance.

The demons are not difficult to deal with, but the real problem is that they are endless and are accustomed to attacking in groups.

Being besieged by demons for a long time without any chance to breathe, even the most powerful cultivator will eventually die of exhaustion of vital energy.

What is even more troublesome is that, as of now, the demons in this world do not seem to be in a hurry to hunt human races after passing through the sky, but instead watch them kill each other leisurely.

When the water of the galaxy completely floods the entire world, in the deep sea where undercurrents surge everywhere, even a cultivator who is good at water escape will not be as fast as the invisible and colorless demon who can move freely.

That will be the day when the world will truly be extinct.

"Demons..." Xu Yinglian asked thoughtfully, "You said they are hovering over the Kunlun Plateau. What are they looking for?"

"I don't know." Qiu Changtian shook his head.

The two looked at each other silently, and suddenly turned their heads to look at the ancient statue of Taiqing Tianzun.

"Could they be looking for this thing?" Qiu Changtian pondered, "If they were looking for this, why didn't they invade this secret place?"

"Could it be because we couldn't find the secret realm before?" Xu Yinglian guessed, "Look, to enter the Tianmen Palace from Fenbao Rock, we have to go through two secret doors, right?"

"And now we have broken down all the secret doors outside, so..."

The two men stared in a daze at the pine and cypress knots that were still oozing water.

I don't know how long it took, but suddenly a column of black smoke rushed out from it.

Qiu Changtian was quick-witted and quick-handed, and he struck the big hole thunder on the spot. Only the black smoke screamed and quickly dissipated without a trace.

"Senior Brother, do you think that if this demon dies here, will other demons know about it?" Xu Yinglian asked with a frown.

"I don't know." Qiu Changtian shook his head and said, "If they do whatever they want, then this demon should not have time to notify its kind."

"But if there is a command behind this demon, and each demon is searching different places separately, then this demon didn't go back, which in itself means that there is a problem in this area. It is only a matter of time before the other party narrows the search range and finally locates us."

"It would be great if we knew how many people are left in the secret realm." Xu Yinglian sighed, "We are hiding in here, and we don't know what's going on outside."

Qiu Changtian did not answer, but continued to wander around the secret realm of Tianmen Palace, asking A Jing to record every corner here.

"In the real world, when you went to the secret realm of Tianmen Palace, I also recorded the situation there." Kunlun Mirror said seriously, "Most of the details of the environment on both sides are the same, only Tianmen Palace and the sky bridge should have been built later."

"Is it the same for pine and cypress?" Qiu Changtian asked cautiously.

"Yes." Kunlun Mirror paused for a moment and said, "When I went to the secret realm of Tianmen Palace, this pine and cypress tree did grow in the same position, slightly below the top of the mountain, but I have not explored whether this passage to the law of heaven and earth exists."

"That is to say, after returning to the real world, I have to go to Fenbao Rock to confirm it." Qiu Changtian said thoughtfully.

Each person and a mirror were checking and comparing, when suddenly they heard an explosion in the distance.

Qiu Changtian hurriedly flew over on his sword and saw Xu Yinglian fighting with many demons. Black smoke covered the entire mountaintop and flames were everywhere.

Although there were a large number of demons, their sizes were reduced by Fa Tian Xiang Di's magical power, and they were burned by the great light fire that could destroy evil and evil spirits, and they were immediately turned into ashes.

"So many at once?" Qiu Changtian landed beside her and asked.

"These demons rushed out at the same time." Xu Yinglian said solemnly, "They must have confirmed our position, so they organized an attack from outside."

"Fortunately, we have the protection of Fa Tian Xiang Di." Qiu Changtian breathed a sigh of relief.

"Can the restrictions of Fa Tian Xiang Di resist the attacks of external demons?" Xu Yinglian asked uncertainly.

After being asked this by her, Qiu Changtian felt a little unsure, so he could only turn to Kunlun Mirror for confirmation.

"Generally speaking, it is almost impossible for a demon or cultivator without spatial attainments to break this restriction of the Law of Heaven and Earth." Kunlun Mirror replied, "But if the opponent has some spatial attainments, as long as he can find the weak point of the restriction and forcibly consume the restriction itself, it is only a matter of time before it is broken."

"Can't this restriction be repaired?" Qiu Changtian asked hurriedly.

"It is possible, but..."

"But what?"

"With your level of cultivation, it's no different from being unable to do it." Kunlun Jing said honestly.

Qiu Changtian was stunned for a long time, but he had to admit that there were indeed many things in this world that only immortals could do.

Just like his current attainments in formations, he could even say that most formations would not be difficult for him, but if he wanted to transform the formations into restrictions and create all kinds of secret realms and caves like the great powers of ancient times, he was still unable to do so.

But in this way, the two of them were like turtles in a jar, and could only wait for the demon outside to make a move.

Fortunately, the opponent seemed to have run out of tricks, and in the next few days, no demons entered the secret realm.

Qiu Changtian and Xu Yinglian took turns guarding the pine and cypress trees. In their spare time, they would meditate or wander around the secret realm.

A few days later, when it was Qiu Changtian's turn to guard the entrance, suddenly a black line shot out from the tumor.

He quickly fired the big hole mine, but saw the black line suddenly change direction and escape from the attack range of the big hole mine. It turned into a beautiful woman in the air and said with a smile:

"So it's the Law of Heaven and Earth. No wonder so many of my men died when they came in."

Qiu Changtian narrowed his eyes, showing no fear at all, and simply asked Kunlun Mirror:

"Why hasn't this guy been shrunk?"

"This is the Great Free Heavenly Demon of Hehua." Kunlun Mirror replied, "The top demon among the Heavenly Demons. To them, the body is like mud and can be shaped at will. It only takes a thought to enlarge or shrink it."

"Can you beat her?" Qiu Changtian asked, but his hands did not stop moving at all. The Tianyuan Yiqi Sword was already raised and the flying sword was aimed at the beautiful woman from a distance.
