The Alchemy Archaeologist

Zhou Ye transmigrates into a cultivation world and is diagnosed with the 'Dan Du Zhi Ti'—any pill he consumes causes severe rejection, from vomiting to meridian reversal. The entire Qingyun Sect considers him useless and assigns him to the chores department, tasked with 'poison testing' since he isn't harmed by toxins. However, he soon discovers a secret: whenever a pill 'explodes' inside him, he can 'see' the pill's complete 'memory'—who refined it, how long it was baked, which ingredients were added too early or too late, what the refiner was thinking, and even how many times their hand trembled. In other words, he is a natural 'alchemy archaeologist'—by eating a pill, he can reconstruct its entire refining history. And the most valuable thing in the cultivation world is never existing pills, but lost pill formulas. Others refine pills through talent; he refines pills by 'eating'—eating a waste pill to restore an ancient formula.
