He stammered a reply, then turned into sword light and flew towards the black book.

Chen Lin smiled secretly, shook his head and stopped teasing the other party. Instead, he took out the slate, input his innate power, and allowed the rules and patterns to appear, and carefully studied it.

But no matter how much research I do, I can't find any clues.

This stone slab is just the key to activate the regular patterns in the cave. There is no mystery in itself. Therefore, this object is reserved for a specific person. That person must be able to activate this black book and leave here.

And although he came here by chance, he couldn't take the black book away, and he couldn't even leave by himself.

Chen Lin glanced at Xiaocao and saw that the other party was using his sword light to slash at the black book, but the black book was motionless and showed no reaction at all.

This was what he expected.

Not to mention the sword light, he had used every means available before, including the spiritual treasure, the magical power, the five-thunder blast, and even the soul-destroying finger, but it was of no use at all.

The only thing useless now is the Thunder God Sword.

He only used pure innate power to test, but did not use the Thunder God Sword to attack. He was worried that the Thunder God Sword would be too powerful and if the Black Book was completely destroyed, he would really be unable to leave this place.

The cave was surrounded by an unknown hard ore and was blessed with strange energy. There was no way he could break through it.

If the secret of the black book cannot be found, the only way to leave is to wait for Princess Gegeyun to return to Baiyun Ranch.

It was precisely because there was still this way that he was not too anxious.

With Princess Gegeyun's ability, she should be able to pull his body directly into the demon world, because Niu Niu has done this before.
