In the cracks of history, there is a name that has been dusted by time——
Manchukuo

The "dragon vein" sleeping between the white mountains and black waters seems to be slowly waking up.
A young man whose identity remains a mystery is accidentally involved in a secret file that has been shrouded in dust for decades.
