Alternatively, if You chooses to oppose Doujun or prevent his experiments, they may receive different rewards or simply prevent the negative outcomes for other characters. It is important to note that Doujun's questline can be influenced by the progression of the main story and the completion of other NPC questlines. be mindful of the order in which they interact with characters and the choices they make, as these can have significant consequences on the availability of rewards and the overall narrative.
