On the surface of the Qing River, a large ship was plowing through the waves.
The part of the hull in contact with the water had many fin-like things flipping up and down.
This was the Mo's Mechanical Art hundred-finned ship, modeled after the fins that assist fish in swimming.
About a dozen men were in the hold, stepping on the water wheel to propel these "fish fins," accelerating the ship's travel.
Of course, it would be even faster without manpower, simply by placing the Path Origin Stone into the array plate carved by Mo's Monk for sailing.
But obviously, using manpower was cheaper.
This large ship could carry two hundred people and was considered quite good within the waterways of Zhuang Country. It belonged to the government, but it also engaged in passenger and cargo transport.
Du Yehu was on this hundred-finned ship right now.
