This is a time of great struggle. Qin, Han, Tang, Song, Yuan, Ming and Qing competed with each other for hegemony. A top student from the modern National Defense University died on a mission and traveled through time to become the legitimate son of the King of Qin. He has extremely high military talents and IQ, a gentle personality and a sharp edge. He is good at making decisions and has a deep mind. He impressed the first emperor Yingzheng and all the officials. He promoted the alliance between Qin and Tang Dynasty, allowing Great Qin to embark on the road to becoming a powerful country. He decided to rebel internally, plotted to seize Jiuding, and suppressed the Xiongnu outside. He always upheld the idea of national justice and aspired to make Great Qin unify the world.
