Shadow Cleaner: Seven-Day Loop

Veteran Zhang Huaiyuan makes ends meet by running a housekeeping company, but life is hard. One day, he gets bound to a mysterious System and takes a job cleaning an abandoned haunted house. The payment is energy coins and an improved constitution.

But the jobs grow increasingly sinister: bloody handprints, ghosts in mirrors, and foul-smelling mops keep appearing. Each completed job loosens the seal a little more.

He gradually realizes that his clients never show their faces, and every address is a place where spirits have been sealed. The System's rewards aren't rewards at all, but bait to feed evil spirits.

He's not cleaning rooms. He's performing a ritual to awaken something that has been sleeping. The seven-day cycle is about to begin, and he has become the final key.

Now the thing has awakened, and it's staring right at him.
