In the Beginning, I Started as the Prince of Yan Kingdom, but I Became the God of War of Qin Dynasty.

He traveled through time and became the prince of Yan State, Ji Dan, and was held hostage by Qin State. His fate should have been to flee to Yan in panic, then send Jing Ke to assassinate Qin, and finally end up being killed by his biological father. But he chose not to take the ordinary path, and decided to conquer the world for Qin Shihuang Yingzheng, sweeping through the five countries and becoming a generation of war god. Just when everyone thought that Qin would dominate the world, they suddenly discovered that the once weak Yan had become as powerful as Qin at some point. He has an invincible Yan army that can rival Qin Rui Shi. The person commanding this army is none other than the Great Qin God of War: Ji Dan.
