Dual male leads: Xuan Ling (the attacking role, a deranged master) x Su Luoqing (the receiving role, a scheming disciple)
Su Luoqing is a child abandoned by the Heavenly Dao. He has an older brother named Moyu. Together with his brother and several friends, he forms the Keys that protect the world. Once every thousand years, they sacrifice their lives to seal the Shadow, repeating the cycle for ten lifetimes. After the tenth lifetime, a new set of Keys is chosen, and the cycle begins again.
After an accident, Su Luoqing mistakenly swallows a Forget-Desire Pill and loses all seven emotions and six desires. By a twist of fate, he becomes a beloved disciple of the Heavenly Venerable Xuan Ling of the Heavenly Dao Sect. But his good fortune doesn’t last. He regains his memories and joins two of his friends to seal the Shadow once more.
The Heavenly Venerable Xuan Ling’s love for his disciple sinks into an abyss. He intends to spend the rest of his life with him once his disciple has finished dealing with everything. Su Luoqing’s fall deals him a devastating blow. He has spent a thousand years laying his plans, all for Su Luoqing.
Reborn, Su Luoqing tries to avoid punishment from his master while cultivating and finding a way to break the deadlock. In the end, he still falls into his master’s hands. He thinks he’s as good as dead, but who could have guessed that his master would force him to marry him? Shocked, Su Luoqing runs away, only to be caught and made to listen to his master say again and again, “Susu, you’re being naughty again.”
