Everything you work hard on is an "experiment" in the eyes of the gods.
"Heaven and earth are unkind and regard all things as stupid dogs."
In the land of Shenzhou, the Immortal Sect is high in the clouds, using the dynasty as a chessboard, and regularly launches wars to harvest "luck", euphemistically called the "Cycle of Heaven". Folks call it the "Three Hundred Years Catastrophe".
Zhao Heng, the prince of the former dynasty, endured the humiliation and shouldered the burden and became the founding emperor of the new dynasty. On the surface, they have been working hard to govern, but they have been secretly planning for twenty years, just to gather the fate of the human race and kill the immortals in the next "catastrophe".
The ultimate confrontation between "chess players" and "chess pieces". Under the dual supervision of the court and the immortal sect, Zhao Heng used mortal wisdom to kill the gods.
When he finally cut off the foundation of the Immortal Sect, he glimpsed the truth outside the world - the so-called Immortal Sect was just a window for a higher-dimensional civilization to observe the "stress response of lower civilizations".
