Yang Fan didn't turn his head, and answered, "I am thinking maybe we could cultivate a plant similar to Boston Ivy. Its roots can secrete a sticky substance to reinforce dams, but it's non-corrosive.
If it's an earthen dam, this plant can prevent soil erosion. If it's a concrete dam, it can cover the dam, reducing weathering effects on the cement and greatly slowing the aging process."
Ling Shuiling immediately praised, "That's a great idea!"
Yang Fan continued, "Besides reinforcing the dam, it must have a very strong adaptability, able to withstand both high and low temperatures, otherwise it will die if there's a sudden climatic change, rendering such a species meaningless.
It also must be as aesthetically pleasing as possible, ideally having a very long flowering period, capable of blooming flowers of various colors. Once it enters the blooming phase, the whole dam will turn into a huge wall of flowers, making the city more scenic."
