In fact, in the previous life, there was also the issue of silt accumulation when building the Three Gorges Dam.
But how was it resolved?
Engage in large-scale infrastructure construction.
Because large-scale infrastructure consumes a massive amount of silt, the silt accumulation problem caused by the dam naturally disappears.
The people of this world probably can't imagine that silt can be sold for money and make a fortune.
"The Ministry of Industry is already researching cement, but who knows when they'll achieve results. Even if they do, excavating large amounts of silt requires mechanisms, as relying solely on manpower is too costly." Xu Qing could only be thankful that there are still soul stones.
Using soul stones to power the mechanisms of the Fang Immortal Dao could also replicate the effects of some machines from his previous life.
