The old man was there to cast a spell with all his might, wanting to reseal this lock demon tower, but this was also the time when the original seal here was the weakest.

"As the saying goes, if it is not broken, it is not established, only by recasting the seal here, it is possible to reseal this lock demon tower for a thousand years. This is exactly what the old man told Li Sibai before.

Li Sibai looked at some demon beasts that ran out of the gate of the Lock Demon Tower from time to time in front of him, and thought thoughtfully, this method of reconstructing the seal Li Sibai naturally couldn't understand, but this didn't prevent him from enlightening a thing or two. Of course, this did not affect him to command those giant ape puppets to destroy those demon beasts that ran out from time to time.

Although these demon beasts were all Heavenly Extreme Demon Beasts, they were consumed when they passed through the seal on the gate of the Locked Demon Tower, and when they came out, they faced the attack of more than forty Giant Ape Puppets of the Tengyun Realm, and most of them died here. Only a small number of demon beasts who were proficient in concealment and retreat, with their own strength in this area, barely escaped the attack of these giant ape puppets.

Of course, although these giant ape puppets are the cultivation of the Tengyun Realm, they are not as good as Li Sibai of the Qin Mental Realm in terms of divine sense, although Li Sibai found that some demon beasts were missing, but he was subject to being distracted to control these giant ape puppets, so he could only turn a blind eye and couldn't take care of it.

Even so, there were more and more demon beasts coming out of the giant gate of the locked demon tower, and Li Sibai couldn't take care of it, and these newly run demon beasts saw that their side was getting stronger and stronger, and they actually began to take the initiative to fight with those giant ape puppets, which made Li Sibai even more careless.

He was only able to control a dozen giant ape puppets to fight at the same time, and more giant ape puppets were autonomous operations, this autonomous mode could only simply deal with some lone demon beasts, once they encountered this kind of siege, they were naturally overwhelmed, and they were quite embarrassed, and after a while, there were several giant ape puppets with injuries on their bodies, and their actions became sluggish.

Li Sibai was anxious and smiled bitterly, although he didn't know how many demon beasts there were in this lock demon tower, but if they all ran out like this, even if the lock demon tower was resealed, how many demon beasts could there be in it.

At this moment, the old man was still suspended in the air, and his body, which was originally a phantom, trembled slightly. Despite this, he was not worried in his heart, even if the situation seemed a little bad for Li Sibai, as long as he could complete the seal here, those demon beasts that had escaped so far were not the strongest in those lock demon towers, so even if they escaped, they must not be able to set off much of a storm in this Seven Illusion Tower.

The only thing to worry about is Li Sibai, once those giant ape puppets can't support it, then it is obviously a great risk for him to face these Heavenly Extreme Demon Beasts with the cultivation of Qin's state of mind.

The old man shook his head and tried not to think about it, "How can there be smooth sailing in cultivation, how can you take some risks in order to have opportunities." The old man muttered to himself.

And now Li Sibai is still struggling to support it, but fortunately, the intelligence of these demon beasts is not very high, and at present, he is only attacking those giant ape puppets, and he has not found that Li Sibai is manipulating them, so Li Sibai is still not in any danger at present.

But even so, there are more and more demon beasts that can't resist running out, and now several giant ape puppets have lost the ability to move and have completely fallen to the ground.

Li Sibai frowned tightly, his divine sense was released, and the vitality on his body was also released, always on guard against a demon beast sneaking up on him. And while he himself was manipulating these puppets, he was already thinking about how to save his life if these giant ape puppets couldn't stop them.

After all, although this space blocks most of the divine sense, it shouldn't be too small, and his cultivation is too low, and these heaven-level demon beasts can't be defeated by themselves, so there are still some opportunities to escape. Myself

Although he promised the old man, his own life was still more important.

At this moment, Li Sibai felt a movement in his chest, and his heart became overjoyed.

There is only Cai Yao in this place on the chest, Cai Yao has fallen into a deep sleep since he returned from the Dark Forest before he entered the Seven Illusion Tower, and it seems that he is about to face a breakthrough.

But whether she broke through or not, Li Sibai was very happy that she could wake up at this moment.

Immediately said to Cai Yao: "How is Cai Yao, are you awake, how do you feel?"

Cai Yao seemed to adapt to the new changes in her body before she spoke: "Brother, I'm fine, it seems to have been upgraded." But where is this, why are there so many heaven-level demon beasts, I was woken up by the breath on their bodies. After speaking, he seemed to be a little unhappy, and his face showed a disdainful expression.

Li Sibai heard Cai Yao personally say that she had been upgraded, and he was happy in his heart, "Cai Yao, this is a secret realm of the Xuantian Sword Sect, this tower is the Demon Sealing Tower, and many demon beasts in it are about to be uncontrollable, what can you do after you upgrade?"

Although Li Sibai knew that Cai Yao was a Heavenly Extreme Divine Beast for a long time, he didn't know exactly which level it was. Cai Yao only showed some skills to assist him in his cultivation before, although most of the time this upgraded skill will continue the original skill type, but for some reason, maybe it is because Cai Yao's performance before the upgrade is relatively special, so he is still very curious about what kind of ability Cai Yao can improve after upgrading.

After hearing this, Cai Yao smiled and said, "It should be a little useful, I'll try it." ”

After speaking, his wings shook and flew out of Li Sibai's chest. After flying high in the air, the feathers stretched, revealing all the seven-colored feathers.

Between Cai Yao's wings flapped slightly, those colorful feathers kept shaking rhythmically, and the colorful glow accompanied by the flapping of the wings, like layers of waves, spread from far and near.

Li Sibai was stunned, he had seen such a scene many times before, and the colorful glow that Cai Yao had assisted him in training before was like this, what did it mean to use it here now?

But before Li Sibai could figure it out, a moment later, when those colorful glows spread to him, Li Sibai's mind was tumbling, and countless distracting thoughts came up, as if he was about to fall into an endless environment.

At the same time, a cool breath came from Li Sibai's sea of knowledge, obviously Yuan Jue activated to protect him, Li Sibai was taken aback, he didn't expect that this thing that seemed to be like a colorful glow was so powerful, and it almost made him fall into an illusion.

glanced up at Cai Yao, and found that she was smiling at herself, presumably she was also testing herself just now, and she didn't put too much mana on her side, so she escaped this illusion.
