Long Chao Da Du

The Dragon Dynasty, an ancient country with a long and deep history, is becoming increasingly prosperous thanks to the invention of the perpetual motion machine. Like a locomotive, the Never-Ending Machine guides the city in its quest for change and innovation.

The story centers on a hero named Long Zhengyi, who has suffered severe memory loss. After waking up in an unknown city, he gradually discovers the hidden truth of the country through the notes he had written before - Dragon Metropolis is nothing but a big cake divided by the great powers. The rotten darkness beneath the surface is the devastation caused by the perpetual motion machine. Moreover, what he discovers in the notes warns him to leave the dying city as soon as possible.
