Nie Sheng looked somewhat uncomprehendingly at Wu Zixiu.
Wu Zixiu sighed, "He used several different methods in projecting a single pill formula, some of which this old man could not even recognise."
"He probably did not have to go through so many steps in projecting and restoring the pill formula originally. He must have intentionally done this due to having seen through our intentions."
"Having comprehended so many principles of the dao of alchemy, it has instead prevented this old man from being able to tell what the true path he follows is. I can only say that his attainments in alchemy are definitely higher than mine."
Wu Zixiu repeatedly shook his head, "He is expressing his dissatisfaction with us."
Nie Sheng looked rather shockedly at Wu Zixiu, only saying after a long time, "In having intentionally concealed his background, this might mean that he has some unspeakable goal."
