The Protector Sword Lord Yun Zhan is a sword of frost that hangs over the entire cultivation world. He protects the human world and suppresses the demonic realm. He has a flawless Taoist heart and has never killed anyone under his sword. Until that rainy night, he met someone who shouldn't exist.
The demon prince Li Ye returned from the abyss and sea of blood, disguised as a romantic monk, and broke into his world. Evil, charming and arrogant, his words are like a knife tempered with honey, and his behavior is like a prairie fire, breaking his indestructible laws time and time again.
"Yun Zhan, your sword is for the world you protect, but my life is only for you."
A series of strange murders involved the civil strife of the demon clan that had been silent for thousands of years; life and death were shared again and again, and the ancient secrets that subverted the three realms were revealed. When the truth about the different paths of immortals and demons comes to light, and when trust is shattered inch by inch amid the conspiracy——
He faced him with his sword, and used his body as a shield.
How will this forbidden love, which begins with conspiracy and redemption, end? When the cold night in the sky falls, can they find their final destination on each other's sword?
