I Play Evil God in the Grocery Store

When Chen Mo woke up, he found himself trapped in a strange grocery store. Nothing here can be destroyed. All he can do is sell goods, make money, and attract customers to maintain his declining mental value—and his own life. Selling goods can be upgraded, upgrading can be expanded, and expansion can unlock new abilities. But every customer who buys the pendant will unknowingly become his mouth, nose and even body. He originally just wanted to live quietly as a grocery store owner. Until he discovered that the abyss believers worshiped him as an evil god, and the world he lived in also regarded him as the incarnation of the abyss, testing, wooing, and encircling him, all with their own agendas. And he himself couldn't even get out. The bigger the store, the deeper the nightmare and the stronger the madness. Maybe he will become the real evil god after all. But the store still has to open, and I am still the store manager. So... Where did the store come from?
