It's quite common to artificially create a grandiose presence at a nation's founding ceremony—be it Great Qian, Great Yu or even Great Xia had made no small stir during their own founding ceremonies.
If one were to trace the source, it could be traced back to Immortal Jiuchong's ascension to immortality.
Therefore, neither Yun Zhi nor Jiang Pingan paid too much attention to the founding ceremony.
Unexpectedly, Wu Yao chose to use the founding ceremony as an opportunity to pass his immortal tribulation and ascend to immortality.
Originally, Nightmare Supreme, relying on his status as a semi-immortal, believed that even if he were defeated by Wu Yao and the Imperial Teacher by chance, so what? He still had the chance to make a comeback.
But he never considered that Wu Yao might have become an immortal.
The mere possibility of Wu Yao becoming an immortal was enough to make him beat a hasty retreat, not even daring to probe.
