Shen Qingci, an amnesiac detective who can see the "price" of all things, got involved in the mystery of the transaction between gods and demons in order to find his girlfriend, and had to sign a marriage contract with his ex-boyfriend Lu Jin, whose identity is a mystery and who has "sky-high price" and "danger" written all over his body. She thought she was tracing the truth, but she didn't know that she was the ultimate auction item with the word "World" on the price tag in the eyes of all buyers.
Concept: A truly priceless thing never needs a price tag. It is priced from the heart and guarded by love.
