The colonel was surprised to hear his lord's words. This is Quicksand Land, and opening it up means occupying less territory, which doesn't quite fit the Emperor Mountain style of doing things.
"Lord, why is this a good place?" the colonel asked curiously.
"Of course it's a good place. If we conceal it now, it will serve as a natural barrier during future sieges," Ling Tianyu replied. "Even if tools can be used to slide over, mechanisms can be set up beneath the quicksand, reducing the pressure on defending the city."
The colonel had considered this, along with setting up mechanisms, but it would not withstand the sheer number of people. Sooner or later, this Quicksand Land would be leveled.
"Once too many people fall into it, the Quicksand Land will turn into an ordinary place," the colonel said.
