Anyway, the Zhen Army has many people. In battles of a few thousand each time, even if mostly defeated, it's still training. As long as the defeated army can escape back to the camp, the loss won't be too significant, not enough to cause damage to the vital parts.
Considering the disparity in national power and manpower, if we can hold the line at the Yingzhou Defense Line, at least wear them down for three or four years, exhausting the edge of the rebel army, depleting their middle-level officers, and cultivating the Zhen Army's officers, only then will both sides have the opportunity for a decisive battle.
The current rebel army, weren't they also honed on the icy front of the Yin Mountain, suppressing demons?
But it's easier said than done to hold the line and confront the rebel army, isn't it?
Didn't the Three Constellations Immortal Army have such plans? The Gen River is much wider, and wading couldn't cross it, yet it was still shattered in one blow.
