Most people won't have enough rice to eat.
If they don't have enough rice, they can only starve to death.
Eating soil, eating grass, even resorting to cannibalism, these kind of tragic scenes will all be played out on this land.
If such a scene really occurs,
ask yourself, if you were a conscripted Wei soldier and you knew that your family back home was facing this tragic situation, would you still have the heart to fight to the death against Chu people?
Moreover, they themselves might be starving and personally experiencing this tragic situation.
If these things truly erupt, the morale of the Wei Army would inevitably plummet, and its people's hearts would scatter.
Let alone fighting, if there weren't a mutiny or rebellion with everyone killing the instigators, it would be like the sun rising in the west.
Just the issue of insufficient grain alone is a deadly weakness for the Wei soldiers on both sides.
