Ethan Vance Becomes an Ancient Son-in-Law

Ethan Vance is a soldier fighting on the battlefront between the kingdoms of Hua and Sheng when an explosion throws him away from his unit and knocks him out cold. He awakens in a prison cell in an unfamiliar world, but his modern weapons are still with him and he manages to break free. Returning to the army camp, he discovers that he is actually the son of Chancellor Vance, a noble traveling with the troops on this campaign, and his true place in this ancient realm is far more tangled than he expected.
