The Undying Heavenly Emperor looked at the Sky-Supporting Great Emperor with uncertainty. The current situation had already exceeded his understanding.
He had endured through the ages for so long not by luck, but because he had found a method of becoming immortal.
By undergoing transformation after transformation amid the mortal world, he had gradually set foot upon the path to immortality.
Yet all of this had a prerequisite: to undergo a qualitative transformation, one had to wait until the twilight years of a lifetime.
Only by undergoing an unimaginable transformation in one's later years and enduring the passage of vast ages could one successfully live out the next life.
He had endured through the ages and gained his present peerless strength through transformation after transformation.
But what was going on with the Sky-Supporting Great Emperor?
If the Sky-Supporting Great Emperor had entered his twilight years, using heaven and earth as a furnace and the myriad Daos as fire, borrowing the hands of Supremes to transform himself, he would not have found it surprising.
There would always be astonishing geniuses in this world. It was remarkable that the Sky-Supporting Great Emperor had reached this point, but no more than that.
Yet the Sky-Supporting Great Emperor had deceived everyone. He had not entered his twilight years at all, but was instead at the peak of his life.
This clearly surpassed his understanding. How could one undergo transformation while at the peak of life?
But the facts were right before him. He could sense that the Sky-Supporting Great Emperor's transformation had been utterly extraordinary.
Just how had this transformation been achieved? It was a question worth deep consideration.
Whenever one entered old age, one's vital energy and blood declined and one was no longer at one's peak. Attempting transformation then was undoubtedly perilous.
