The greatest threat he feared was that if his soul were annihilated, it would neither return to the Realm God Continent nor to the reincarnation of this world.
If that happened, his true self would fall into slumber, and he would truly be doomed.
Even though the possibility was slim, he dared not take the gamble.
Currently, he could not endure the absorption of the blood light. Once he entered the altar, he feared he would have no choice.
Therefore, he decided to self-destruct his soul before entering the altar.
Don't forget, his soul body within the Nine Prison Pagoda was considered the true self in this world.
However, the Nine Prison Pagoda originally belonged to Immortal Jiu Chen, and he worried that Jiu Chen might have tampered with it. Thus, he wanted to destroy his current soul to prevent Jiu Chen from gaining any leverage over him.
