Modern materials engineer Shen Yan traveled through the troubled times of Jingkang in the Northern Song Dynasty and built Taohuo Village among the refugees in the north. He established a stronghold with military firearms and stabilized the people with a republican system. He resisted the iron hooves of the Jin army externally and defeated the Song court's encirclement and suppression internally. He swept north and south all the way, destroyed the decadent Jin and Song Dynasties, and ignited the spark of peace in the troubled times.
