"Hmm?"
Yin Tian looked at the King in surprise, not expecting him to say such a thing.
"Do you know about the Hidden World Clans?"
The King asked in a soft voice.
Yin Tian shook his head, indicating he did not know.
"Hidden World Clans, transcendent and reclusive, seldom venture out into the world, only choosing to reveal themselves at special times. The books in your hands were entrusted to me by someone from the Hidden World Clans to auction off on their behalf."
"What do you mean?"
"According to them, these ancient books contain tremendous opportunities, but the Hidden World Clans have never been able to fully comprehend them. Thus, they thought to disperse the books, to have more people assist in understanding them."
"Then why is only one book auctioned off each year?"
"Because these ancient books were obtained through great effort and difficulty from various places."
The King said softly, "So in fact, even they do not have a complete collection of the books."
