Having lived for tens of billions of years, Lin Changsheng has become the most powerful person in the universe, and all laws are unified. Endless time has obliterated all emotions. Although the universe is big, it is just a gorgeous cage for him. Loneliness and ennui are his only companions.
In an accident, a system named [Harmony and Friendship Exchange Group of All Heavens and Worlds] was suddenly bound. The "rookies" from all over the world are noisy and stir up troubles in the stagnant life. The boring daily life of the retired Emperor of Heaven was finally broken.
With nothing to do, Lin Changsheng transformed into a "cutie" and sneaked into the group chat. He casually instructs the loser boy, speaks out tricks to create the sun for the apocalypse, and plays games in the human world to subvert the heavenly ways of other worlds... In the process of helping (or teasing) his friends, he found fun for the first time in a long time.
However, Lin Changsheng gradually discovered that this group chat was far from a simple cheat. It seemed to have its own consciousness and had other expectations for him. When the group mission attracted not rewards, but "cleaners" who could annihilate the world, a bigger mystery emerged: Why did this group chat that connects all realms find him, the retired Emperor of Heaven, alone?
