Li Sibai looked at the scene in front of him in surprise, these iron sand were floating in the air at the moment, completely fused together, Li Sibai only looked at it for a moment, and his mind "buzzed" and understood.

"I see...!No wonder I felt a little familiar before, but I never understood it. Li Sibai said to himself, his face was expressionless at the moment, but he was overjoyed in his heart.

The patterns presented by these iron sand are just three-dimensional representations of the patterns on the stone walls, and this three-dimensional presentation made Li Sibai realize almost instantly that it was the spatial criterion contained in it, and this spatial criterion was closely related to the "awl" type magic weapon used by Wu Feng to break the space at that time, so Li Sibai felt both familiar and unfamiliar before.

Looking at this hard-won space criterion, Li Sibai was excited, but he remained sober again.

The spatial criterion involves the comprehension of spatial ability, and Li Sibai has also seen some introductions in the library of the sect, but this spatial criterion is too advanced and profound, and it is not something that his level of cultivation can comprehend.

But now that the situation is compelling, he can't get out of here without understanding some spatial guidelines, and the spatial guidelines here may be because of the reason why the iron sand has been suspended and turned into a three-dimensional presentation, Li Sibai feels that it is not so obscure, so at this moment he completely calmed down, sat in the middle of the entire secret room, closed his eyes and comprehended this spatial law.

Time passed minute by minute, about half a day passed, Li Sibai suddenly opened his eyes, and an imperceptible smile appeared on the corner of his mouth.

Just now, he had comprehended some of the power of spatial principles, and he believed that with this knowledge, he could successfully break through this space.

Looking at the suspended iron sand around him, Li Sibai re-sacrificed the Xuantian Sword in his hand, and under the continuous input of vitality, the Xuantian Sword in his hand was wrapped in golden light, Li Sibai shouted, and the Xuantian Sword in his hand continued to fly, and he continuously shot out the sword against a position.

One sword, two swords, three swords, at the beginning, there were only some faint fluctuations in that position, four swords, five swords and six swords, the fluctuations there are getting more and more severe, and it seems to be a little unstable, the sword in Li Sibai's hand is getting faster and faster, seven swords, eight swords and nine swords, and a loud sound of "bang!" was heard, and a small hole appeared in the place where it was attacked.

Li Sibai did not hesitate, his divine sense was released to detect that there was no danger in the space outside, and a group body flew out, and with a return move, the iron sand suspended in the secret room also flew out with his figure.

Li Sibai looked at the hole that was constantly returning to its original state, and there was no joy on his face, so he felt a little regretful.

With his understanding of the power of the spatial criterion just now, he used the continuous nine swords to replace the "awl" type magic weapon used by Wu Feng and them, which broke through the space, and if he had that magic weapon in his hand, he would also only need one moment to break through the space here.

And this secret room doesn't know which master arranged it, it actually contains an understanding of the power of space guidelines, if it weren't for the urgency of time, Li Sibai really wanted to stay in it for a while, after all, this kind of opportunity is not always encountered.

"With my current cultivation, it's already good to be able to understand these, maybe no matter how long I stay in it, I won't be able to comprehend more of the power of spatial principles if I can't cultivate. Li Sibai could only comfort himself like this.

The most important thing at the moment is to find out your location and situation, I have been in it for too long just now, and those previous colleagues don't know if they have gone out.

The divine sense was released, and the purple light divine eyes also scanned the surroundings, and Li Sibai found himself in a narrow aisle.

On both sides of the aisle, there were countless secret rooms, and Li Sibai found that the same divine sense could not enter them for a long time. But these rooms are different from the previous secret room, they all have doors, and inside the door, looming, Li Sibai seems to feel some familiar atmosphere.

Li Sibai easily found the door closest to him, and a large amount of vitality entered his eyes, and the purple light divine eye immediately saw the scene in the room clearly.

There was a white tiger lying on the ground inside, with a bright silver chain tied around its neck, the chain was the thickness of a bowl, but it was glowing with blue light, and it seemed to have a faint power of thunder and lightning, and the white tiger itself had its eyes closed, and the expression on its face was stable, as if it was sleeping.

"Could this be a White Tiger Demon King?!" Li Sibai had seen the introduction of this White Tiger Demon King in that "Strange Things", and according to the introduction in the book, this White Tiger Demon King turned out to be a kind of Heavenly Extreme Demon Beast, Li Sibai had never seen it, but he didn't expect to see it here, which surprised him.

Looking at the second chamber again, a huge electric eye lizard was prostrate on the ground, with a bright silver chain around its neck, and its eyes seemed to be asleep.

And if Li Sibai remembers correctly, this electric eye lizard has always been a heaven-level demon beast!

Next, Li Sibai checked almost all the secret rooms here, Shura Black Wave Snake, Feng Xu Yan Heavy Spider, Wheel Flame Five Elements Phoenix Bear, Starry Night Golden Martial Jiao and other heaven-level demon beasts all appeared in front of Li Sibai, and there were many that could not be named, but they should also be Tianji demon beasts.

And they were all in a state of deep sleep! This surprised Li Sibai, and at the same time muttered in his heart, where are so many cherished demon beasts here?

Li Sibai was surprised in his heart, but he didn't stop under his feet, and before he knew it, he had come to the end of this aisle, and here, there was a wide door of dark gold standing in front of him.

"This is?!" Li Sibai felt more and more surprised the more he looked at it, on this gate, there were all kinds of strange patterns depicted, like some kind of Sanskrit statue, giving people a sense of sacredness, and the fighting spirit in his body seemed to be oppressed by some kind of pressure at the moment, and he shrank to a corner of his body, unable to mobilize it at all.

Li Sibai wondered in his heart, the Sanskrit statue on this door seems to be some kind of mark of Buddhism, and it appears here, so where is he?

After thinking hard but still having no clue, Li Sibai was heartbroken, "That's it, let's see what is behind the door first!"

After trying a few times, the fighting qi in his body could not be mobilized here, Li Sibai touched the huge door with one hand, and wisps of pure true qi entered the door from the palm of his hand, but this true qi disappeared without a trace like a stone ox entering the sea.

Li Sibai frowned, and his other hand also touched the door, and at the same time, the true qi was output from both hands, and the speed was more than twice as fast as just now.
