Tian Zong, an ordinary college student, traveled to the late Qin Dynasty and became a servant in the family of leader Tian Heng. He explored deep caves on the seabed, killed giant pythons, built strange ships, and developed gunpowder. Modern knowledge, arrogant character, and the teachings of many generals with unique skills gradually made him an invincible and handsome commander. Adventures continued to appear in various oceans, allowing him to obtain dragon pills that could improve his skills, and swords that could cut iron like clay. He also captured the hearts of wealthy ladies, well-behaved maids, singing girls, exotic girls, and even enemy beauties. . .
