Long Chao Da Du

In the prosperous Dragon Dynasty, the invention of the perpetual motion machine has driven the city of Dragon Metropolis toward unprecedented innovation and growth. However, beneath its gleaming surface lies a hidden rot, as the machine's true cost begins to surface.

Long Zhengyi, a hero suffering from severe memory loss, awakens in an unfamiliar city with no recollection of his past. Through notes he wrote before losing his memory, he uncovers the dark truth: Dragon Metropolis is a divided territory carved up by great powers, and the perpetual motion machine has brought devastation rather than salvation. His own warnings urge him to flee the dying city before it's too late.
