This story happened after the gods were conferred, the saints retired, Kunlun Mountains were closed, and all religions were eliminated. The strength of the entire prehistoric world has regressed and it is no longer prosperous.
The third great tribulation has receded, and the gods are at ease. In the heavenly court, Emperor Haotian kept the list of gods close to his body. After the Lich Tribulation, the Demon Court was changed to the Heaven Court. Ancestor Hongjun ordered the boys Haotian and Yaochi to jointly take charge of the Heaven Court.
