This is just speculation but I think that the ml is the legendary character that was renowned for fulfilling all his missions without using a single tool (seems obvious) but I also think that Wang Yi was his AI… the one that took a human form and became human which is why they banned AI from taking human forms from then on out. Anyways they say that Qin Xian went crazy because of the power he obtained to be able to read minds, but it might’ve actually been because Wang Yi died. Since his soul shattered and scattered then that might be why there is always a Qin Xian in every world Wang Yi goes to.
