When the heaven and earth first opened, spiritual beings were born and divided into two, one yin and one yang, one good and one evil. The two were born with enlightenment. There are three thousand avenues, all of them are accessible and all of them are unknown. And this is what they are distressed about. Without pursuit, life is meaningless. Therefore, they sealed their memories and reincarnated in the three thousand worlds. Only when they broke through the limits of this world could they recover their memories and continue the next reincarnation. Both are spiritual beings and have no gender distinction. Therefore, in reincarnation, sometimes they are born as boys and sometimes as girls, and for unknown reasons, the two of them will appear in the same world every reincarnation, and there will be various ties in the process of growing up.

Life after life, this seems to be a rule that even omnipotent spiritual beings cannot break. However, this does not prevent the two from continuing to find fun in reincarnation. But all enjoyment and willfulness will always have to pay, and every reincarnation will touch the rules of heaven and earth. The spiritual beings that are supposed to guard the rules have repeatedly broken the rules. In the end, in this life, they encountered heaven's punishment, and what greeted them was death. Spiritual creatures reincarnated and were born in Zhongzhou Continent. In this life, they are two brothers. They are the eldest son of the Nangong family, one of the four major families, and the prince of Zhennan King. When their wings are not full, a human tragedy is about to hit them...
