"The cost is too high, and it doesn't provide much protection."
"How come it doesn't work?"
"Commander, you've seen the terrain underwater. It's uneven, with highs and lows, plus the shape of the boats isn't very regular. Not to mention the difficulty in finding enough boats, even if we do find them, sinking them won't provide much protection. Instead, it would artificially change the flood flow direction, making the dike even more dangerous."
Seeing the commander and Vice Mayor Zhong deep in thought, Han Yu picked up a pen and quickly sketched a diagram on paper, explaining as he drew: "Once the boats sink, how do we plug the holes beneath the boat's bow? How do we handle the junctions between the boats?"
All these will alter the flood direction, turning the previous overall force on the dike into multiple stress points, leading to the flood washing out large cavities!"
The commander frowned tightly and asked, "Are you saying that sinking boats won't work?"
