Without Di Jun's instruction, they could accept such a result.
But with Di Jun's directive, they needed to keep trying to entrust themselves to the River Map and Luo Book together.
The relationship between the Good Corpse, the Evil Corpse, and the Self Corpse was not one of competition, but one that required cooperation to accomplish this task.
A single individual entrusted within would not suffice; all three needed to be able to entrust themselves at the same time.
Under these circumstances, the Three Corpses began to continuously try.
They took turns entrusting themselves to the Innate Undying Spiritual Light within the River Map and Luo Book while the other two tried to entrust themselves anew.
Without a doubt, they failed.
The exclusivity of the Innate Undying Spiritual Light was too strong; when one was entrusted within it, the other two could not enter.
So they all left the Innate Undying Spiritual Light and began to try other methods.
