He is not someone with whom another human in this world can deal
Considering the current condition of Bai Zemin, it was impossible that there would not be some mutinies and usurpers trying to take his position. After all, greed was a really powerful emotion and not for nothing was it part of the seven deadly sins recorded in the Catholic bible and in many other legends.
Although Bai Zemin tried to rule as well as possible, it was impossible for him to do everything right and therefore it was impossible to keep everyone happy. There were always some who would feel that what they were getting was not enough or who would be dissatisfied with the way he led.
Bai Zemin was fully aware that once he left the gray corridor and his broken body was exposed to the eyes of everyone there would definitely be at least one person who would rise up against him. However, even Bai Zemin could make wrong judgments at times.
