The Floating Boat Airship Fleet arrived in Guan Tuan County, delivering a total of thirty thousand stones of cargo, the vast majority of which was grain.
Originally, the design of a single floating boat had a cargo capacity of only five thousand stones. However, the Qingming tradition is known for its fine craftsmanship and solid materials, so as they kept loading, they discovered after reaching the set load that the flying boat could still hold more. Unknowingly, they loaded from twenty thousand stones to thirty thousand stones, and the structure of the flying boat still held strong, only the oarsmen got a bit tired, so Zhang Sheng brought two additional groups.
