Tianchao is where eternal spring resides, and where blood and war prevail. Taken from his home nation of Tianchao and raised into a powerful commander and government official of one of five Xiaoweis, Yang Zihun is ferocious Xiaowei of Spear, a cunning and exemplary image of a soldier, a loyal dog of an emperor. Ten years later, Zihun had been sent to his long forgotten home nation of Tianchao, but with one simple mission: Kill the Holder of the Mark Heibao, the ferocious and brutal rebel prince of Tianchao who started the DaiZai-Yige, the intranational civil blood war. After a bizarre, powerful bloodlust sent Zihun to chase and to attack the rebel prince of Tianchao, he is forced into a situation where he must contend with court politics of a hostile emperor who'd rather seen him dead, a brutal prince who would cut his throat from a mere sign of betrayal, and the dark past haunting him from his childhood. While even then, he gets pulled into the bloody corruption under the bleeding moon of Tianchao where his goals begin to shift to a more sinister and darker path.
