Outside the Nine Heavens, the four emperors of green, white, red and black occupy the four directions, restraining each other and maintaining the balance of the heaven.
Back then, they only fought to preserve themselves. Thousands of years later, a shocking change occurred at an unexpected moment. The balance is broken, and no one can stay out of it.
When we first met, he was just the son of the Heavenly Palace Emperor who was depressed and at the mercy of others; but he fell from the ninth level of the sky and fell around him like mist by accident.
I thought he was just a little immortal who had lost his memory. He kept him by his side and wanted to give him the ultimate pampering, just because he felt that they were too similar.
Unexpectedly, with his father's words, he turned into his brother. Although their identities have changed, their friendship has not changed, but a series of drastic changes in Black Emperor City have made them unable to control the direction of their destiny.
The color of the world changes, the situation is chaotic, and the price of ascending to the throne is really that you can no longer see the person standing behind you when you look back?
