Ever since Yu Yuan left, Wen Zhong devoted himself wholeheartedly to the improvement of the Linhuan Pass.
Besides teaching children, he used the rest of his time to instruct the people of Linhuan Pass to fell trees from the forest and drag them to the river to construct a giant wooden device.
This device was called: Water Wheel.
The Water Wheel didn't rely on Divine Skills, nor did it require Daoist Skills.
It rotated upon encountering water, ceaselessly day and night.
When the Water Wheel turned, it could draw the waters of the Huai River up onto the bank.
Seeing that the Water Wheel really could draw water, the doubts of the people of Linhuan Pass vanished altogether. On one hand, they continued to build more Water Wheels after the model, on the other hand, following his suggestions, they constructed irrigation canals, dredged the riverbed, piling the silt dug up from the river's shores into the fields.
