After thinking about it, Li Sibai felt that he had to go out of this room first, after all, there was a divine sense prohibition here, and he couldn't determine his exact location, and only when he went out might be able to find a clue to judge where he was.

And although his divine sense was blocked, but just now under the observation of the purple light divine eye, he still saw some clues, this confined space is surrounded by stone walls, but there are no doors, but some patterns can be faintly seen on those stone walls, which seem to be very mysterious, making him have a sense of familiarity.

It's just that these patterns seem to appear alternately, looming, and it is not possible to fully see his full picture.

Li Sibai flipped his wrist, and there was an extra Xuantian Sword in his hand, and under the gaze of the purple light god, he stabbed at a wall. Said it was a thorn, but in fact it was a sword brandished on the wall, and he actually wanted to draw those looming patterns.

But after a while, Li Sibai stopped and frowned at the same time. Just now, he took a lot of effort to draw the pattern, the back has not been finished, the front has disappeared out of thin air, and the stone wall has returned to its previous appearance at this moment, and there is no sword mark at all.

Li Sibai frowned at the moment, obviously the patterns on this stone wall had a lot to do with leaving here, and he didn't hesitate to consume his vitality to portray them, just to have a good understanding, but he didn't expect that this stone wall could recover on its own.

At this moment, if he spares no effort and continues to depict it many times, he will be able to familiarize himself with this pattern, but the effect will definitely not be good, and it will consume a lot of vitality. Although it is not difficult to memorize these patterns by memory, these patterns seem to be connected with the stone wall, and the group case memorized alone does not seem to have that mysterious feeling, which makes Li Sibai have a headache.

Li Sibai hesitated slightly, and there was an extra gourd in his left hand, which was his gourd with iron sand.

I saw Li Sibai carrying the Xuantian Sword behind him, with a shake of his right wrist, iron sand squirted out of the gourd, flying towards the other stone wall, and then a vitality was struck, and the latter came first, fused into those iron sand, and the two showed a faint gold after fusing with it, and after encountering the stone wall, it stopped, and it was attached to the stone wall.

Li Sibai did not relax for a moment because of this, and continued to manipulate the iron sand in his hand to the stone wall continuously, and in a moment, almost half of the wall was attached to the iron sand, and a clear picture appeared in front of Li Sibai.

But Li Sibai couldn't be happy at the moment, this method was to use his vitality as an adhesive, so that the iron sand was barely attached to the stone wall, although it could show a pattern, but it still didn't have the mysterious feeling before, so it was useless at all.

Li Sibai was not discouraged by this, sat cross-legged, closed his eyes and began to think while pranayama, although he did not consume much just now, but now he is in an unknown environment, and he also hopes to be able to keep himself in the best condition at all times.

After a cup of tea, Li Sibai's eyes lit up, he stood up, and once again sacrificed the Xuantian Sword in his hand, and the iron sand that was originally attached to the stone wall was withdrawn into the gourd, and the gourd was also placed on the ground close to him.

Under Li Sibai's purple gaze, with a wave of his left hand, a cloud of iron sand erupted from the gourd again, and the Xuantian Sword in his right hand stabbed at the patterned wall.

In a moment, those sword marks emerged, and at the same time, without waiting for those sword marks to heal, the iron sand controlled by his left hand was quickly stuffed into those sword marks, and after doing all this, Li Sibai did not stop, but continued to perform the action just now alternately with his left and right hands.

After a while, beads of sweat the size of beans appeared on Li Sibai's head, although this continuous operation does not consume too much vitality, but it is extremely challenging for people's minds, although Li Sibai's divine sense is strong after being tempered by Zizhu, but this kind of subtle operation still makes him feel a little unbearable.

However, he persisted in this way until most of the stone walls were filled with iron sand, and when Li Sibai looked at this stone wall again, a smile appeared on his face.

I couldn't tell what the pattern meant, but the subtle and familiar feeling seemed to return.

Li Sibai came to his senses all of a sudden, he had been here for an hour, and he should not have been in a coma for a long time before, but he didn't know what was going on outside, so getting out as soon as possible was something he urgently needed to do now.

Thinking of this, Li Sibai took an elixir that helped restore his consciousness, and re-followed the method just now.

In this way, about two more hours were consumed, Li Sibai's face turned pale but he couldn't hide the joy in his heart, looking at the pattern in front of him that was completely clear, the entire pattern had been completely filled by him with the Xuantian Sword and iron sand, at this moment there were two different colors on the stone wall, and the black pattern presented by the iron sand was much darker than the cyan color of the stone wall itself. Li Sibai sat cross-legged at the moment, carefully looking at the pattern in front of him, pranayama and recovering again and again, and comprehending the essence of this pattern.

The pattern on the wall had struck him a familiar one from the start, and though it was irregular, it felt familiar, as if he had seen it recently.

Li Sibai carefully recalled some things that had happened recently, staring intently at the stone walls around him, and did this for another half an hour, but he still had no clue.

Obviously, he had a familiar feeling with these patterns, but he couldn't find a way to start, and he couldn't pierce that layer of window paper, Li Sibai was obviously a little anxious, and punched a stone wall, as if venting his anger and annoyance.

"Huh?!" Just after Li Sibai punched the stone wall, the iron sand that was originally embedded in this stone wall was shocked out, and Li Sibai shouted in his heart that it was not good!

After a few breaths, the iron sand stopped, and just suspended there, the grains vibrating slightly in a certain position, as if calling for something.

At the same time, the iron sand of the other three stone walls seemed to feel this call, and even trembled slightly.

Li Sibai was overjoyed in his heart, is this the way to break the ban here?

No longer hesitating at the moment, three consecutive "bang bang bang" punches out, hitting the three stone walls respectively, those iron sand are really like the iron sand on the first stone wall before, slowly floating towards the middle, after a few breaths, the whole room has been covered with iron sand.
