The greatest value of reincarnating as an ancient immortal was actually the memories in their minds!
These memories included everything they had experienced, seen, and touched before they were reincarnated!
Although memories were things that could not be seen or touched, they were in fact a huge fortune that could bring many unexpected benefits.
For example, if Tai Yi did not remind him, Chen Xiaobei might have the demonic Dragon's edge, but he did not know if it could counter the demonic essence.
Perhaps, Chen Xiaobei would only realize this after he had suffered a lot.
However, all Taiyi had to do was to point it out and Chen Xiaobei would be able to solve the problem that everyone thought was a dead end.
This was the value of the ancient immortal's memory.
In the Three Realms, Taiyi was a top quasi-Sage, second only to the heavenly path Sage.
