There is a taboo bond about protection, secret love and uncovering the truth between Yan Jin, the new demon king who carries the unawakened demon fire and supports the Nine Netherlands alone, and Xuan Chen, the emperor of heaven who transforms into a mysterious Taoist priest and sneaks into the demon realm quietly.
In the past, there were many doubts about the death of the Demon Fire King and his wife in battle, and the thousand-year prophecy predicted that the Demon Fire would shake the sky. Xuan Chen came here as promised by his father, but hidden under the cold appearance is the deep-rooted love and admiration that he has cultivated since he was a child. He approached in the name of chasing the murderer, melting the sharp thorns around Yan Jin's body bit by bit with the sunset glow on his fingertips and silent care. Yan Jin, who was in deep trouble, gradually became addicted to this powerful and gentle protection through dependence and temptation, but she didn't know that under that robe was actually the Supreme Being of the Three Realms.
The two work together to track down past conspiracies, go deep into dangerous situations, and experience life and death together. There are constant treacherous and turbulent situations along the way, Jiuyou's internal troubles are not over, and the murderous intention in heaven is coming again. When the truth opens a cruel corner and points to the hypocritical master in the highest place, how should they choose? Should we fight against each other, or should we abandon the shackles of the three realms and join hands to rekindle the fire that burns the sky?
This is a beautiful legend in which the Demon King and the Emperor of Heaven redeem each other, grow together, fall in love with each other amidst conspiracy and war, and finally burn out lies and redefine the world.
Intention: Secret love for each other
