Bloodthorn Flower!
Thistleblood Sect!
Chen Yang stared at the symbol around the eye socket on the inside of the mask, immensely shocked.
During his previous return to the Qingyun Daoist Temple, he had learned from his master that the Bloodthorn Flower was the emblem of the Thistleblood Sect.
He had never expected that the leader of the Sanctuary would be a member of the Thistleblood Sect.
No wonder the leader of the Sanctuary gave him the impression of a ninja, because the Thistleblood Sect was the predecessor of Ninjutsu. Although they didn't use Ninjutsu, there were still similarities in their techniques.
When cross-referenced with the words of that Westerner, Chen Yang suddenly realized the truth.
The leader of the Sanctuary was indeed searching for something, and just like "Sane" who was utilizing Japanese Ninjutsu factions, he was looking for martial arts Secret Manuals.
