Mu Caisang was known as the Poison Immortal, her mastery of poison techniques was so profound that it seemed otherworldly. There was probably no one else in the world who could merge poison arts so seamlessly with their body except for her. Even Tang Manhong, who was recently referred to as the Poison Empress, still had a considerable gap compared to Mu Caisang. What puzzled Tang Ye was that the living Gu within Murong Mu Yu's body greatly resembled Mu Caisang's poison techniques—could it be that Mu Caisang was the one who had placed the living Gu in Murong Mu Yu?
Previously, Tang Ye had never considered this possibility. After all, the living Gu had been placed in Murong Mu Yu over a decade ago. At that time, Mu Caisang had just emerged from Miao Jiang and was barely in her twenties—how could she have possessed such advanced knowledge of Gu poison and witchcraft? It was likely that Mu Caisang had not yet reached the pinnacle of integrating poison arts with her body back then.
