By the water well.
Watching the well water swiftly flow through the stone column's pipes, Xu Yun's expression grew increasingly grave.
As an engineer, how could he not know what this phenomenon implied?
It was obvious.
Somewhere in the middle or at the other end of the pipe, there must be some mechanism generating suction.
However, given that the maid Yue Lian was supervising the site, Xu Yun could only temporarily shelve the many thoughts swirling in his mind and start drawing water with Zhang San.
The East Wing of the Su Mansion was a guest room, currently unoccupied.
Thus, their task was relatively laid-back; they only needed to fill the water for the main house and the West Wing.
After about a quarter of an hour.
All twenty buckets of water were poured completely.
Yue Lian replaced the cover on the stone column and locked it securely before saying to Xiaosan and Xu Yun:
"All right, Third Brother, Wang Lin, you can go have your breakfast now."
"Yay!"
