The Red Devil Sword is not easy to use, so there is no need to think about the Nine Lives Soul Banner. Although the Nine Lives Soul Banner is of a higher grade, it is not a sharp weapon after all. Yuan Tian wanted to simply try Shennong's Measuring Ruler, hoping that the attack of that green light would be effective.

What's going on, what Yuan Tian thought about was to use the Shennong Measuring Heaven Ruler to repeatedly strengthen the outer wall of the Treasure Hall, and wait until the number of times was enough to launch a green light attack. But Shennong's measuring ruler had just come into contact with the outer wall, but it was like knocking into the water, and the whole ruler fell directly into it.

The place where Shennong's measuring ruler came into contact with the outer wall of the treasure hall directly turned into translucent green. Yuan Tian carefully touched it with his hand, and he was able to put his hand inside. It was as if a key had opened a door, and the performance of this Shennong Measuring Heaven Ruler in the Land of Chaos was too amazing.

Yuan Tian was holding the Shennong measuring ruler in front of him as if he was swimming, and he himself staggered in. The outer wall of the treasure hall is really thick enough, and it takes several zhang to swim in it before you officially enter the inside of the main hall. Yuan Tian even had an idea, if the Heavenly Realm was really destroyed, would it be okay to hide here.

Even the Red Devil Sword couldn't make a mark on the outer wall of the treasure hall, and this wall was several feet thick, so it really felt like it was invulnerable.

Of course, this is just a thought, even if it is really possible to avoid natural disasters here, it is impossible for Yuan Tian to hide in it from now on. After all, there are so many relatives and friends outside, and Yuan Tian can't let go of them and leave them alone.

It's such a tall hall, thanks to the fact that I didn't go around to find the entrance just now. After entering the hall, Gentian looked up, and the top of the main hall was far from the ground. This treasure hall as a whole is very large, and if you just went around from the outside to find the entrance, you don't know how long it will take.

Hey, the layout of this hall, the supporting pillars, and the way all kinds of things are arranged are so familiar.

Yuan Tianxian walked around the neighborhood and took a look, and the layout of the entire hall reminded him of two places. One is the mysterious cave mansion next to Tianyuan Mountain in the cultivation realm, and the other is the stone mansion under the bottom of the Luohe River, where the earless stone monkey took him to intrude unintentionally.

Both of these places are related to the Gun Emperor, and this place is very similar to those two places, but it is much grander and more advanced than those two places.

A place of this grade could not have been built by the Spear Emperor, it should be said that it was not built by a Heavenly Realm monk, at least not by a Heavenly Realm monk known to Yuan Tian. Then it can be considered that the old man of the Gun Emperor imitated this hall, so he built the two halls in the back.

In fact, Yuan Tian only guessed half right, the Spear Emperor did imitate the structure of this hall. However, only the cave mansion in the cultivation realm was made by his old man and then brought down, as for the stone mansion at the bottom of the Luohe River, it was not built by him, but a finished product, and it was found from the surroundings of the treasure hall in front of him.

Yuan Tian didn't bother to surround the treasure hall, in fact, there were really some things around it. Because this treasure hall is not only a hall, but also a back garden, which means that part of it is exposed.

It's just that I don't know what caused the sinking of the treasure hall. Therefore, whether it is the main hall itself or the surrounding facilities, they all sank into the ground. The Gun Emperor found some treasures when he was wandering around the back garden.

From the ancient twins, Yuan Tian heard some meanings, the Spear Emperor and the Sword Emperor were more powerful than the ordinary Demon Emperor and Immortal Emperor, and the reason why these two people had stronger strength was inseparable from the Land of Chaos. Now that Yuan Tian sees this treasure hall, he seems to understand everything, at least the rise of the Gun Emperor has a lot to do with it.

Yuan Tian was indeed right, not only the Spear Emperor but also the Sword Emperor also got some benefits from here, but the two of them did not enter the main hall, but both of them got some benefits from the back garden, that is, the periphery.

The stone mansion that the Spear Emperor got that could change its size freely contained many treasures in itself, such as weapons, armor, and elixirs. It was precisely because of this that after he arrived in the cultivation realm, he imitated a stone mansion of that kind again.

As for whether the internal purchase structure of the stone mansion is the same as the treasure hall in front of him, his old man doesn't know at all. Because neither the Spear Emperor nor the Sword Emperor could enter the Treasure Hall at the beginning, even if they were already very strong at the beginning.

Shennong's measuring ruler was something that Yuan Tian had found in the immortal ruins, and it was buckled from a broken door frame. If it weren't for his carefulness, he wouldn't have found this ruler at all. It was a wooden ruler with no energy fluctuations, and it was also inlaid on the same wooden door frame, which was not easy to find.

Think of the broken immortal relics, and then think of the ancient battlefield that is also withered. These places all seem to have existed in the Celestial Realm, and they are more advanced than the existing environment in the Celestial Realm. I just don't know why they all fell and became a compressed independent space.

Is this what the so-called Heavenly Realm Annihilation means, it will be like the ruins of the immortal realm, or it will be like a lifeless ancient battlefield with only a pile of bones left. It seems that no matter how strong the monks are, they all died one after another in that natural disaster, and none of them were spared.

Yuan Tian thought of the black chip he had picked up on the ancient battlefield, which should have collapsed from a powerful weapon. Just such a collapsed horn is more powerful than the current Demon King Weapon Sword. What kind of power was it in the first place, and what kind of weapons were used to be able to do this?

The body of that powerful man was not found on the ancient battlefield, whether he died in battle and disappeared, or found a new way out. This source heaven is unknown, and even the existing masters in the heavenly realm are unknown.

However, there is one person who seems to know something about the ancient battlefield, that is, the old man who had observed Yuantian on the periphery of the Illusory Demon Sect at the beginning, but had never made a move. I remember that when Yuan Tian killed Elder Ye, Elder Ouyang, and even Lin Yixuan's father, Lin Keyi, that old man had seen it.

Especially when he saw the pitiful appearance of the deputy sect master of the Phantom Demon Sect, the old man once sighed.

This old man who has been hiding behind his back and refusing to show his face is actually the founder of the Illusory Demon Sect, that is, the former old sect master. He had entered the Ancient Battlefield earlier than Yuan Tian, and had studied some of the situations over there, and knew that it was the place where the former Demon Cultivators had fallen.

Xiaolong was going farther and farther away in the ancient battlefield at this time, always looking for the direction of the demonic wind. The magic dragon spear he was holding in his hand was given by Brother Yuan before.
