At the time, the fleet is being ravaged by scurvy, but Qiu Yu uses modern medicine to bring the sick back to health. Later, when they face violent storms and threats from pirates, he relies on the intelligence and courage of a special forces soldier to lead everyone out of danger. He earns Zheng He's trust, and the two become sworn brothers.
After completing his mission, Qiu Yu retires to a deserted island with a group of beautiful women who have fallen for him. Using his knowledge of modern science, he leads them in farming and developing the economy, while fending off pirates and Western colonizers.
