Indeed.
Some of the True Immortals in the Sealed Heaven Land who had lost parts of their bodies actually had the ability to undergo reincarnation rebirth, but they had not done so.
For one thing, they had already lost parts of their bodies. Without finding those missing parts, restoring their true immortal cultivation would be almost impossible even after reincarnation rebirth.
The other, most important reason was that although reincarnation rebirth could allow cultivators to be reborn into another life, it carried considerable risks.
After reincarnation rebirth, not all their memories would follow them into their next life. Only as they cultivated and slowly recovered some of their cultivation and power...
Could they gradually unlock those sealed memories from before their reincarnation and recover them...
To put it simply, after reincarnation rebirth, before they gained sufficient cultivation and strength, they were just like ordinary cultivators. They could only rely on their own cultivation to increase their power, and they might be killed by other cultivators before they ever reached the point where their memories could recover...
Of course, reincarnation rebirth also offered considerable benefits. One was preserving their lives. Another was that reborn cultivators could generally retain their original spirit root attributes and bloodline aura. In terms of talent, they would absolutely rank among the finest cultivators...
That was also why some cultivators occasionally mistook Ye Han for a powerful being who had undergone reincarnation rebirth...
Thus, although reincarnation rebirth could preserve their lives and offered tremendous benefits, it was also extremely dangerous. It meant abandoning the undying lifespan they had finally gained after becoming True Immortals through so much hardship...
Unless they were like the Night Spirit Immortal Emperor, suppressed by Ye Han with absolutely no chance of survival, they would never choose reincarnation rebirth.
It was like that
