This should be the inheritance of the Ancestor of Medicine.
There's even Supreme Elixirs in there aimed at experts at the Peak of the Divine Emperor Realm.
This kind of elixir is called the Divine Emperor Nine-Turn Pill. Although taking it doesn't allow one to directly step into the Eternal Life Realm, at the very least it lets a Peak Divine Emperor take a huge step forward within that realm, vastly boosting combat power. After all, between the Peak of the Divine Emperor Realm and the Eternal Life Realm lies an extremely vast gulf.
Even so, this Divine Emperor Nine-Turn Pill is already amazing enough. It would absolutely drive those Peak Divine Emperor Realm experts mad with desire. Nowadays there are almost no Supreme Elixirs that can raise the strength of Peak Divine Emperor Realm experts, not even by a tiny bit, and once you reach the Peak of the Divine Emperor Realm, wanting to take even a small step forward is incredibly difficult.
