Li Cheng froze. He immediately took a small notebook from his pocket and said with a trembling voice, "Please continue. Don't mind me..."
He had originally wanted to refuse, but he could not refuse this knowledge.

At the same time, He Ao recalled the book on Talent Sequences he had seen at Deres's place.

This was relatively easy to verify, because among the Rank C to Rank B Talent Sequences He Ao had encountered so far, the serial numbers of C and B always differed by seventy-two, and there was a one-to-one correspondence between Rank C and Rank B Talent Sequences.
Moreover, He Ao suspected that there might also be a unique succession relationship between Rank A and Rank B. Rank A might also have seventy-two Talent Sequences, but he could not confirm it for now.
Besides that, He Ao had obtained another key piece of information from that book.
The contents of this key information did not come from the book itself, but from a photograph of what appeared to be a fragmented manuscript.

The manuscript in the photograph was very simple. It was a
