Ye Xuan flees to the county town with his wife, where he meets the heroic swordswoman Wang Yifei and carefully investigates the truth behind the massacre. Watch how this modern-time trader uses modern weapons to fight his way through a dark world, build a commercial empire in another realm, and embark on a path of revenge and a triumphant comeback!
