Bai Zhi, a modern gangster young man, unexpectedly traveled through the Warring States Period of Zhao State and became a "poor boy" of unknown origin. He has no one to rely on, only his charming "sister" Bai Ling to accompany him, and he can barely survive by relying on the martial arts secretly taught by his sister and his rogue temperament. In the marketplace of Handan, he was an "extraterrestrial" who could call the rich and powerful's children a brother. He made jokes in the streets with Ying Zheng and Gao Jianli and weathered the difficulties together. No one knew that this demon king had a mysterious identity and was sent to the Kingdom of Zhao to be raised. When Yingzheng returned to the Qin Dynasty, Bai Zhi also embarked on a journey with his "rules of survival" and used the cunning and ruthlessness of modern people to stir up the situation in the Qin Dynasty. From a small "troublemaker" to a "mad dog of the Qin Dynasty" that frightened the six countries, in the confusion of power, swords and life experience, he wrote a Warring States legend in which friendship and ambition are intertwined!
