"It's nothing too exciting. That is the remains of a Nine-Life Cat. It is their leftover genes," Old Cat said with a slight tone of awkwardness.
"Does that mean there is more than one?" Han Sen asked.
Old Cat hesitated for a moment, and then said, "There aren't many."
"What's going on?" Han Sen frowned. Old Cat wasn't answering fully and forwardly, and it was clear he was hiding something.
Old Cat retreated into thought before speaking next. He said, "It's not a big secret. Only rare Nine-Life Cats can leave behind something like that. And to the best of my knowledge, there are only ten."
Hearing him say this, Han Sen's mind drifted back to Zero, who had the exact same thing. He still went on to ask, "How many are there in the sanctuaries?"
"Just one. It was from Human Emperor..." Old Cat suddenly stopped short.
