To be honest, Fang Lin really had not decided who to take as his mentor, and deep down, he was somewhat reluctant to have one at all.
In Fang Lin's view, no one was qualified to be his master, especially in the realm of Alchemy Tao. Having been the Pill Sovereign in his past life, there was no one left who could instruct him.
If he really were to take a master, Fang Lin seriously doubted who would be teaching whom.
Despite his reluctance, Fang Lin knew he had to choose someone to be his mentor.
Accepting a mentor was not ordinary. To a large extent, it was not about finding a master, but finding a support.
If Fang Lin wanted to gain a solid foothold in Purple Mist Sect, finding a support was indeed necessary, apart from improving his strength.
Although Han Yinyue could offer Fang Lin a considerable amount of help, considering her status and relationship with Fang Lin, this help would be very limited.
But if Fang Lin were to have a mentor, it would be entirely different.
