Hua Haoyu, the last descendant of the Heavenly Master, was ordered by his master to go down the mountain to practice spiritual practice, and came to the prosperous and strange Lanjiang City. He has only one mission: to find and protect the "Destined One" because the prophecy states that she will be the key to the catastrophe of the Three Realms.
However, when he found the so-called "destined person" - the popular actress Bai Xingyan, everything went wrong. Not only did this eldest lady make things difficult for him, the "Heavenly Master's Bodyguard", she also had a strange aura about her that even ancient jade slips couldn't analyze.
Hua Haoyu originally wanted to complete the task in a low-key manner, but found that his every move was being watched by various forces: the cultivation family, the hidden sect, and even the demon clan that had been sleeping for thousands of years were preparing to make a move. And the secret of Bai Xingyan seems to be more terrifying than the catastrophe of the Three Realms itself...
When the seal was loosened and all the demons were about to come, Hua Haoyu discovered that what he was guarding was the key to saving the world, or the switch that destroyed everything?
