After dying, Sang Yan transmigrates into a novel called Vanquishing Demons, where he becomes a cannon-fodder spy the cultivation world planted in the demon realm.
The day he arrives, his identity is exposed, and he is locked up in prison as an assassin.
Another high-profile prisoner is held there too: Fu Xuanye, the cultivation world's greatest prodigy.
Fu Xuanye is peerlessly handsome and extraordinarily gifted, a once-in-an-age genius and the revered senior brother admired by everyone in the cultivation world.
During a dangerous excursion into a secret realm, Fu Xuanye exposes his demonic bloodline while saving his fellow disciples. His spiritual roots are destroyed and his golden core is ripped out. In a single night, the heaven-blessed prodigy falls from grace and becomes a despised cripple.
Forced to turn to demonic cultivation, Fu Xuanye confronts the Demon Venerable alone and protects the entire cultivation world. But when he is gravely wounded, his closest junior brother and his master join forces to kill him.
As a devoted fan of the Demon God Fu Xuanye, Sang Yan swears to change his fate, no matter what!
Sang Yan: I like you so much! You're amazing! You're exceptionally talented! So don't ever sell yourself short! You have to stay alive. As long as you're alive, all your dreams and comforts can come true. Don't give up...
Fu Xuanye: ?
Sang Yan protects Fu Xuanye like a mother hen guarding her chicks.
He helps him escape his enemies, restore his spiritual roots, and rebuild his golden core, making him a powerhouse no one in the three realms dares to cross. He even secretly arranges an engagement between Fu Xuanye and the heroine.
Satisfied, Sang Yan packs his belongings and finds a quiet place to retire.
But Sang Yan has no idea that, during the few days he was gone, Fu Xuanye went mad searching for him.
