From this point of view, the Sage's Key is indeed highly compatible with Fang Mu.
The true Sage's Key is hidden within the thick crimson-gold shell. The material of this shell is unknown, but after absorbing Fang Mu's blood, it has started to show signs of separation and disintegration.
However, judging by the current rate of progress, it will take at least six to seven days to completely peel away the shell.
In other words, Fang Mu will have to wait six or seven days before being able to contract the true Sage's Key hidden within the shell!
Fang Mu had originally thought that by injecting his blood into the Sage's Key, he would be able to contract it immediately.
However, Lin Zhi did not mention to him that the Sage's Key would gradually disintegrate its crimson-gold shell after absorbing his blood.
It seems the Wise Cat Clan is merely searching for so-called descendants of sages but doesn't know the true details of contracting the Sage's Key.
