Traveling Through 1937: the Ghost of the Island

Those who are harmless to me can live; those who have contributed to the country are respectable; those who want to kill me - must die! Traveling through 1937, I opened my eyes from purgatory. When the bricks and stones smashed the head of the first invader, a system called [Mountains, Rivers, Blood and Tears] awakened in the darkness. I, Jiang Xiaolong, am wandering in the darkness from now on, using absolute rationality as my ruler and ruthless survival as my blade: those who are harmless to me can live; those who have done meritorious service to the country, are respectable; those who want to kill me - must die! This is the darkest age and the loneliest battlefield. There are no flowers and applause, only silent protection and precise judgment. Until the night before dawn, the success is achieved and the legend fades into dust.
