In the last years of the Daqian Dynasty, there were treacherous ministers in power, powerful enemies outside, wars were raging, and the people were in dire straits. Murong Yi, the generalissimo of the Northern Territory, emerged from the sea of blood and corpses, holding the most elite warriors of the dynasty. He originally wanted to be a pure minister loyal to the country, but due to the suspicion and frame-up of the court, and the lamentations and expectations of the people, he was forced to take a completely different path step by step. When loyalty becomes ridiculous, when the object of protection has long been rotten, he can only choose to kill to end war, fight to end chaos, and use the knife in his hand to carve the word "safe" again for the world.
