The slave soldiers around him didn't know how to ride horses, so Xia Pingan easily snatched a horse from the military governor. Riding on it, he followed the main Army and charged towards King Zhou's Army.
On such a battlefield, it was easier for people to understand the true meaning of the phrase "an Army defeated like a mountain."
What was like a mountain collapsing?
It was like a domino effect on the battlefield.
The collapse and defection of the slave Army directly collapsed King Zhou's regular army behind them. The moment King Zhou's vassals started to run away, the entire Army of King Zhou broke up with low morale.
King Zhou's 5000 catapults then collapsed. After the catapults, the strongmen who were strong enough to lift a cow and throw a stone turned and ran.
The 18 Giants held the burning wooden stakes in a daze, then turned around and ran.
