However, this kind of rebirth did not necessarily happen in a logical way. Perhaps, in order to achieve the purpose of rebirth, he would have to pay a special price.
This could be seen from the number of times Yi Chang and churong had been reborn.
Yi Chang was the leader of the Requiem clan. His position was the highest, equivalent to the clan leader. He was the spiritual leader of the clan and was indispensable. Therefore, he had to constantly be reborn through the long river of time, which was why he had been reborn the most.
If one considered being less than 80 years old as one reincarnation in his life, he had been reincarnated 12 times so far. In other words, he had lived for at least 900 years, almost 1000 years old.
In comparison, churong's dress had less than half of his, only five or six layers. This meant that churong had lived at least half of his life.
