[Online Game + sole player + maximum satisfaction + not mindless + absolute payback]
The city you live in is actually a real-person Online Game.
Going to work is a daily quest, dating is an affection system, and the stray cats and dogs by the roadside are outdoor mobs.
Wang Qing only finds out on the day his engagement is called off. The ring he picked up is a game controller, the old key at home can be bound as a respawn point, and killing fish or slaughtering pigs counts as grinding mobs. You can even get real money as drops!
While everyone else is still rushing around to make a living, Wang Qing is already calculating: kill one LV2 breeding pig for 50 EXP, get a Yellow-rank item for 8 Attack, then clear the stray dog dungeon and he'll reach LV5...
What, your ex wants to get back together? Sorry, NPCs aren't qualified to date players.
