In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

After the nth time of failing a marriage meeting, Xiang Han got himself a job: good treatment, high salary, free world traveling with food provided, house provided and even a ‘lover provided’?!

At first, he thought, apart from having to travel into the body of a scum cannon fodder, a scheming fake white lotus, everything else was okay. It was only later he realized that saving the target was also a problem. His imagination was neverending, even eating a cup of ramen was seen as a way to rouse his ( target’s) interest!

Xiang Han: This target is a no-go.

Certain Target: Very good, you’ve already managed to rouse my interest.

Xiang Han: Go outside and make a left turn to the optometrist, go get your eyes healed! Additionally, this “lover provided” isn’t necessary.

A Certain Target: This is certainly necessary!
