Strategy to repel the enemy

Everyone looked at the mountain peak that had been fired upon 12 times with an automatic rifle, then at the confident soldier who shot it.

To be honest, everyone, including P5092 and the others, was surprised. That was a mountain! But that soldier said that as long as those 12 points of the mountain could be turned to sand, the entire mountain would collapse?

To humans, those towering mountains were not something that could be destroyed with human strength unless they used firearms and explosives.

Ji Zi'ang asked, "How large of a cross section should I turn to sand?"

The soldier answered, "Just 1.38 centimeters in diameter. Of course, you might not be able to control it so accurately, so you just need to achieve around one and a half centimeters of sandification horizontally. That should be within the limits of your power."
