Zhang Zimo is the most conscientious Immortal Emperor in the Three Realms. He approves memorials until late at night every day and manages the Immortal Realm with KPIs. He is the most deviant Demon Lord in the Demon Realm. He fishes and lies around all day long, but he plots secretly. When changes occur in the Meteor Star Sea, these old enemies are forced to form a team, and a cooperation full of trials and confrontations begins.
In the ancient mirror of Huan Xin, they glimpsed the deepest secrets in each other's hearts - the Immortal Emperor who had been alone for ten thousand years, and the Demon Lord who was forced to grow up. From being wary of each other to relying on each other in life and death, from opposing ideas to being connected. However, the ancient prophecies reveal the cruel truth: the existence of the Demon Lord itself is a threat to the survival of the Three Realms.
When the evil god from outside the territory came, the immortals and demons forced her to execute him with her own hands. On the execution platform, she raised her sword and pierced his heart, but she heard him whisper with a smile: "Don't cry, this is my voluntary choice."
She spent all her life's cultivation and held his cold hand: "This time I will chase you."
From then on, the rules of the Three Realms were completely broken. The barrier between immortals and demons melted, and a half-immortal and half-demon tree of loneliness emerged from the ground, witnessing this love that transcended life and death, and also opened a new era of the Three Realms.
