During the troubled days of the Dayin Dynasty, Shen Yan, a modern science student carrying half a broken star, traveled through time and became a young farm boy in the south of the Yangtze River. He relied on scientific thinking to establish himself in the countryside, studied martial arts under his master, and integrated science and logic to create "scientific and martial arts solutions."
Deep in the palace of the capital city, the third prince Xing, holding the other half of the broken star pendant, is approaching. He has endured humiliation since he was a child. He combines street fighting and assassination techniques to create shadow killing techniques. He secretly builds power and stirs up trouble in the government. He takes advantage of the palace changes to go to the extreme. He controls the court with iron-blooded means and wants to control the world.
The two met due to the fetters of the Broken Star Pendant, but because of their chivalrous ways and desire for power, they went from pretending to be friends to turning against each other. Coinciding with the invasion of Shuofang's wolf cavalry and the rebellion of the Youxu sect, the world was in danger. The two temporarily put aside their personal grudges and joined forces to defeat the enemy and destroy the evil sect. However, the fundamental contradiction was difficult to resolve. In the final showdown in the Hall of Supreme Harmony, the Broken Star Pendant shattered, and both of them suffered losses. Finally, a check and balance pattern of "the chivalrous guard guarding the south of the Yangtze River, and the emperor controlling the divine capital" was established. A Broken Star Elegy tells the ultimate game between chivalry and lust for power in troubled times.
