In the year 198, Cao Cao, Prime Minister of the Han Dynasty, ventured to the east and defeated China’s greatest warrior Lu Bu, terrifying every ambitious warlord across the country. Several years later, after taking the Han Emperor under his wing, Cao crowns himself King of Wei. He built a magnificent Bronze Sparrow Island to symbolize his power and rumors spread that he would replace the Emperor. Meanwhile, young lovers Mu Shun and Ling Ju are taken from a prison camp to a hidden tomb, where they spend five cruel years together, training as assassins for a secret mission. In the year 220 astronomical signs predict dramatic change. As a result, Cao’s son Cao Pi and Cao’s followers urge Cao to become the new Emperor – but unknown opposing forces plot against him.
