This is a chaotic era of the Republic of China where superpowers and guns dance together. Li Yao, the ace of the Japanese superpower unit "Crow", is known as the "Blade of the Empire" because he is of Chinese descent. During a mission, he came into contact with ancient jade, and the suddenly awakened memory of Chinese blood was fiercely torn between the loving control of his adoptive father. When he discovered that all superpowers were just weapons consumed by all forces, he chose the most dangerous path: dealing with the Japanese invaders, military commanders and underground parties, establishing a secret sanctuary for superpowers, and trying to conclude a "Dawn Pact" that transcended nationality and camp. In this era where superpowers determine the direction of the war, he will use the blade in his hand to carve out a new path to dawn for his kind and for this land.
