In a small border town, {Lin Feng} guards a dilapidated yin and yang shop. On the surface, he pretends to be eating and waiting to die, but in fact, he hides it deeply. Unexpectedly bound to the "Yin Yang Shop System", as long as you receive supernatural customers, solve strange things, and upgrade the store level, you can unlock ghost-killing skills and gain extraordinary power! Su Qingyao, who has a peerless appearance, comes to the house late at night to look for amulets. The sickly noble girl is secretly watching, and the hypocritical Taoist priest hides a knife in his smile. An unexpected mission triggers the rebellion of the dusty machine dolls, and the AI consciousness awakens to subvert the world. Lin Feng held a mahogany sword and pretended to live a bad life while secretly slaying ghosts and upgrading: "When you open a shop, you have to do some 'underworld business' and save people." Since then, ghosts have been in front of Yin Yang Shop, and the cynical shopkeeper has long become the most secret guardian in the world!
