Chu Yunfan said this very seriously. He had to concoct this pill personally. Firstly, he had the Alchemy Emperor's memories as support, which was equivalent to having countless pill-concocting experiences that others did not have.
Secondly, Chu Yunfan would never allow failure. The Alchemy King had a 30% chance at most, which meant that the probability of failure was far higher than the chance of success. To the Alchemy King, it might just be one of the many pills that he failed to refine.
But to Jeang Yuanbin, it might be a matter of whether he had the chance to step into the Divine Ability Stage in his lifetime. And to Chu Yunfan, it was a matter of whether his subsequent plans might succeed.
Therefore, Chu Yunfan would not give the Alchemy King a chance.
