Would the two patriarchs of the Shi Family not have the Three Yin Candles Blood?
99%, they do!
The combat ability of the patriarch of a martial art family clan was the foundation.
If one's combat strength was lacking, no matter how outstanding one's abilities were, one would not be able to become the patriarch.
Even if he does manage to become one, he would not be able to hold the position for long.
The logic was simple.
The people below would not be convinced!
For example, would a fourth-grade martial artist listen to the whims of ordinary people?
Most would not!
A small part would, but because of other reasons.
This was especially so for the patriarch. If his own strength was insufficient, he wouldn't even know when he has been assassinated by the enemy forces.
