Zane was driving home from work when the world changed. Thousands of dungeons spawned at once, taking up every inch of Earth—including the road he’s driving on. He wakes up to a totaled car and a broken leg, facing down a goblin trying to spear him through the guts. And that's just the start of it.

The luckiest of us might even become one of them, they say—if we serve the Dynasty well enough and harness the power of Qi. But I want none of that. I'm sick of serving, and I want nothing to do with their world. Instead, I want them to pay for what they did to mine.

An AI calling itself Schema has assimilated Earth into its System. As a consequence, everyone gained access to status screens, power-ups, and skills.

For Daniel, however, it's closer to a nightmare.
