Beginning and End had always been two sides of the same coin.
They were not two different existences.
This also meant that Beginning did not only occupy the starting point of time, but also the end of time.
This was already the extremity of the Peak Return to Void Realm, the same level as Cui Heng's current realm.
Hence, a competition in time was no longer meaningful to the two of them.
Beginning controlled time at the beginning to bring forward the final end of countless years, intending to let Cui Heng die at the hands of End.
However, Cui Heng also occupied the endpoint of time.
After sensing that the final moment of death was about to arrive, he also controlled time and delayed this end point indefinitely. Through constantly modifying the future, he made the extreme state of emptiness grow further and further away from him.
However, this situation seemed to make Beginning even happier.
