First of all, the timing of the two of them leaving the forward operating base and the appearance of the snipers at Mt. Dashi was so consistent it was difficult to explain.
According to P31921, Ren Xiaosu's reason for leaving the base was so he could go into the mountains to pick some medicinal herbs. However, P5092 was certain Ren Xiaosu's medicine was not an ancestral remedy. Instead, it was conjured up by Ren Xiaosu's superpower. Otherwise, it would not have such a miraculous effect.
Others might still be superstitious enough to believe in secret ancestral remedies, but P5092 only believed in science. Science was what told him there were no secret ancestral remedies in this world that could make a wound heal in just three short days.
Alright, one might argue the plants had also mutated, but to say that the remedy was passed down from their ancestors, did the plants already mutate when their ancestors formulated this remedy? That was the flaw in the story!
