After the sparring was over, eventually everyone forgot the manifestation of an Empress. The world would forget about it, not until the manifestation of Heavenly Dao occurred.
The Manifestation is when the 5 Heavenly Continents reunited, the Continental Wall broke and the Providence of the Myriad Martial World returned.
It is because Eastern Heaven or any other part of Heaven cannot carry the idea of an Emperor appearing. The idea of an Emperor in this generation is valid but never a young Emperor at this time.
This is the time when the last generation of the last era and the first generation of the new era are interchangeable with each other.
Those who were born at the time of Heavenly Dao manifestation are the 'Heaven Chosens' with talent that could suppress the old. Their cultivation is fast and their Providence is one that everyone would envy.
Those Heaven Chosen however would envy the talent known as Yun Haoran.
