Appearance of the Cave Mansion's Owner

The King of Blood-Thirsty Bat looked at Su Yang and knew that this was the last chance given to it. If it didn't agree, it would face the consequences in the next second.

So, the King of Blood-Thirsty Bat could only show weakness and said, "If I hand over this cultivation method, will you really let me go?"

"Of course, a gentleman's word is as good as his bond," Su Yang smiled.

"Alright, I'll trust you this time," the King of Blood-Thirsty Bat gritted its teeth and agreed.

Then, it flew towards the Thousand Years of Milk. Su Yang and the purple lightning lion frowned simultaneously, not knowing what this creature was up to. However, at this point, they didn't dare to play any tricks.

As Su Yang expected, the King of Blood-Thirsty Bat didn't play any tricks. Instead, it picked up a book from under the Thousand Years of Milk.

The book looked worn out, but under the nourishment of the Thousand Years of Milk, it appeared somewhat whitened.
