Before transmigrating:
An orphan, a professional assassin in the cultivation world, whose final assassination target turns out to be a lover who vanished years ago.
They elope, are hunted by the organization, and seek a doctor for the lover. The orphan becomes a renowned physician, but by the time they return, the lover has passed away. (In truth, the lover made a deal with the Butterfly God to save the male lead, then transformed into a butterfly.)
The male lead leaps off a cliff for love and unexpectedly transmigrates to the mortal world.
After transmigrating:
He becomes the personal bodyguard of a cold-faced female CEO.
He unexpectedly becomes a crime boss, too.
He also gets caught up in a scandal with a famous actress.
He opens a health soup house with a little girl.
In the end, he meets the butterfly that his old lover became,
unravels the secret, and journeys to the Heart of the Desert and the depths of the ocean.
