Given Elder Liao's current condition, it was clearly infeasible to have him stand up and execute a punching routine. The fastest way was to knock the other party and analyze him through the Library of Heaven's Path as an artifact.
Previously, he could still rely on medicinal herbs to knock others out, but that would not work on a Saint 7-dan expert like Elder Liao.
"Utter nonsense!"
Before Elder Liao could say a word, Divine Healer Bai Yu had already lashed out furiously.
As the head of the Sanctum of Sages' Physician Guild, he had a deep understanding of the various diagnosis methods out there, and this was inclusive of those eccentric and unorthodox ones. But one that required the patient to be knocked out… Pardon his ignorance but he had really never heard of something like that!
