Cold Knife Sets Mountains and Rivers

At the end of the Eastern Jin Dynasty, the powerful families were at odds with each other, and Hu Qi took a look south. Liu Yu, a young man from a poor family in Jingkou, took over the ancestral black sword "Iron Horse" when his father died. The knife was rusty but slightly warm, leading him into a shocking mystery that spanned three hundred years. They maintained their aloofness through a cycle of war. From a coolie on the riverside to a pawn in Beifu, from the bloody battle in Feishui to the top of Zhouzhou Mountain, Liu Yu relied on the rusty knife in his hand and his fierce strength to struggle forward in the conspiracy and war. Brothers were sworn in and broken up, and their true love stayed with each other but left forever. He climbed all the way to the top of power, was proclaimed emperor by Zen, and founded the Southern Song Dynasty. However, when he finally faced the ultimate truth, he discovered that the most cruel opponent was his former self, which was gradually eroded by power and responsibility. This is a bloody journey that is ignited by the original intention of chivalry but ends in the loneliness of the emperor.
