Ling Wen has immortal mermaid bloodline
His flesh and blood can heal wounds, and his heart's blood can cure all diseases and prolong life.
For this he suffered a lot and lived in hell
And the person who stands at the pinnacle of power doesn't want his flesh and blood
But what he wants
it's his heart
The man in red clothes said, "I don't need immortality, I just need you."
If I don't have you in my long life, the world will be gray and white
Concept: Love that supports each other in the whirlpool of power
