The boundary wall is a barrier between two worlds. It is generally invisible, material and formless. Only through the extreme force can one contact, break through the boundary wall, and achieve the connection between the two worlds through the boundary wall.

However, in reality, the boundary wall is more stable than space because it is the foundation of a world.

To give a more popular analogy, in a huge building, there are rooms separated by different sizes. Some rooms are larger, representing the world of the world, and some rooms are smaller, representing the world of the world. The walls separated by the big room and the small room can be seen as the walls between the big room and the small room.

A boundary wall like the prehistoric world is probably equivalent to the exterior wall of the entire huge building, full of steel and concrete. Not to mention ordinary people, even if they are real boxers, they will have to break their bones and tendons when they hit them, and they will not be shaken at all.

If the boundary wall is punched, it will naturally be connected to other worlds.

Looking at the three-foot-square hole not far away, Ye Xuan was naturally extremely shocked because he wanted to break through the boundary wall of the prehistoric world, according to his estimate, at least a strong cultivation man with the Hunyuan Daluo Jinxian could do it.

And who can have such ability in this blood-colored forbidden area?

Three figures soon appeared in Ye Xuan's mind, the ancestor dragon of the dragon clan, the phoenix ancestor of the phoenix clan, and the first Qilin clan.

This is the ancestor of the three ancient tribes, and the strong man who reached the peak of his cultivation back then. He was able to lead the appearance of the heavenly way. It can be seen that the ancestors of these three tribes have extremely strong cultivation, and they may have surpassed the realm of Hunyuan Golden Immortal and reached the realm of Hunyuan Daluo Golden Immortal.

Another point is that according to the great witch of the Zunrong Tribe before, this blood-colored forbidden land was the ancient battlefield of the three ancient tribes that year. The three ancient tribes fought each other in order to seize the position of the protagonist of the world, but later the Qilin ancestor died here.

This is a bit strange. You should know that since the Qilin clan can be compared with the Dragon and Phoenix clans, the Ancestral Dragon and the Phoenix Ancestor can reach the realm of the Hunyuan Daluo Golden Immortal after making the vow of heaven. This means that the Qilin ancestor Shi Qilin, the ancestor of the Qilin, must have also had the same realm as the Ancestral Dragon and the Phoenix Ancestor. Otherwise, the Ancestral Dragon and the Phoenix Ancestor could completely kill the Qilin from the beginning. Wouldn't this reduce an opponent?

Since the Qilin clan that year was able to rise up countless Yuanhui and stand above the prehistoric tribes, and be known as the three prehistoric tribes together with the Dragon and Phoenix tribes, it can be seen that the Qilin ancestor's cultivation must have been very strong at that time.

Ye Xuan even had a bold guess. The ancient tribes were regarded as the place where the three tribes fought, but the Qilin ancestor died here, while the ancestor dragon and the phoenix ancestor survived. Then the three tribes battle might have hidden tricks.

Ye Xuan himself is a cultivator, so he naturally understands the rules of fighting among cultivators. If the Qilin Ancestor is really too poor in cultivation, then the Ancestral Dragon and Phoenix Ancestor would have removed him long ago, so how could he keep him until the final battle?

Perhaps, before the three tribes' war, Zulong and Fengzu had a secret agreement that the two of them would fight Zulong and Fengzu together during the three tribes' war. In this way, this could make sense why Zulong and Fengzu were able to escape unstoppably during the war, but Qilin's ancestor died in that war.

Another point is that if the Shi Qilin was actually killed in battle, the battlefield would not have become such a blood-colored forbidden area this time.

Don’t forget that Ye Xuan has experienced all the heavens and all realms, and his knowledge is much richer than other people. The dark yin energy in the blood-colored forbidden land has been seen a lot in the world of Uncle Jiu. This kind of yin energy that only produces in the underworld is also called ghost energy. The reason why ghost energy is produced in the human world is because there is still resentment before the person dies.

There is no place in the ancient world like Netherworld, and this blood-colored forbidden land can actually produce Netherworld Yin Qi. It is likely that the resentment of Shi Qilin before his death has gathered and caused a change, which has formed this strange blood-colored forbidden land.

The three-foot hole in front of me is likely to be the strong attack that might threaten the Hunyuan Daluo Jinxian when the three tribes fought each other. It was a powerful attack that might have threatened the Hunyuan Daluo Jinxian, so it broke through the boundary wall of the prehistoric world.

At this time, Ye Xuan thought of the space crack that he had killed the bone spirit before. Perhaps it was also the space crack that was created by an extremely powerful man. In this way, it is very likely that such a cave that penetrated the boundary wall was not the only one in this blood-colored forbidden area.

After all, there were three powerful people from Hunyuan Daluo Jinxian when the battle was fought here. Since a broken boundary wall could appear here, it is naturally possible that there would be broken boundary walls in other places.

Looking at the colorful light flashing in the three-foot cave, Ye Xuan's eyes flashed. Behind the boundary wall, there was probably nothingness, and there might be another world.

Ye Xuan decided to cross the boundary wall and try it. Anyway, the blood-colored forbidden area he is in is extremely dangerous now. Maybe the bone spirit equivalent to the Daluo Golden Immortal turned his head again, or it is very likely that the forbidden existence in the depths of the forbidden area is paying attention to him. Even if there is nothing opposite the boundary wall, with his cultivation level, there is nothing to be afraid of. Even in the depths of the starry sky and above the sun, he can't do anything to him.

But he could take this opportunity to heal his wounds directly, at least he could expel the strange aura in his body first, otherwise he would not know what would happen if he dragged it down.

Even just now, less than a quarter of an hour passed, the strange aura in his body had eroded one-tenth of his immortal energy.

Can't drag it on any longer!

A firm look flashed in Ye Xuan's eyes, he looked at the three-foot hole, and then jumped down.

Rumble!!!~~

Suddenly, colorful light flashed, and Ye Xuan felt the endless laws turning into thunder in an instant, intertwined and bombarded him.

The eternal immortal essence planet in Ye Xuan's body was circulating, and endless immortal essence rushed into his body in an instant. Mysterious talismans appeared in his skin in an instant, possessing an immortal aura to resist the bombardment of these laws.

If the laws of this world wall are intact, even if the quasi-saint arrives, they may die here. Fortunately, the world wall here has been penetrated, and there is a loophole in the world wall and no one has repaired it. Therefore, the laws here are not complete laws of the prehistoric world, which also allows Ye Xuan to pass through here safely.
