This is an examination that puts your life at stake. Answer a plethora of questions, pass the exam, and you may live.

Two-faced examiner, Qin Jiu, meets the cold examinee, You Huo. In this inhumane system, both of them who have lost their memories go head to head against each other.

Despite that, they have a strong mutual understanding. Alarms go off and the system collapses time and time again. During which, their memories gradually return.

It turns out that even at the end of the world where there's only dust left, you're still the first person I met.

What's so great about this system? We'll just destroy it.

The world is brilliant and grand still, so welcome home.
