章 364: Humans Need A Hero

Su Bai looked at his contract book. The contract book had completely fused with the knowledge book. Now, it could be said to be the strongest contract book among the Pet Tamers. There was no other one like it.

The Book of Knowledge of the mermaid Recorder of All Things was formed from the first strand of water origin that had been separated from Chaos. As long as it was something that happened in the endless void, it could be found in this Book of Knowledge no matter how much time had passed since it happened.

Even if it was a secret that had been deliberately hidden, clues could be found in the Book of Knowledge. This book could be said to be the most powerful treasure in the endless void.

The reason why the mermaid had died was related to this Book of Knowledge. The existence of the Book of Knowledge made it so that secrets that were deeply hidden could potentially be exposed to a third party.
