The 5th Year of Zhengyong, November 5th.
Xu Mujun utilized the power of the Thunderbolt and the Red Coat Cannon to bombard Black Mountain Pass.
The walls of Black Mountain Pass collapsed halfway through the day, and most of the buildings inside the pass were destroyed, with countless soldiers of Wu Country trapped under the ruins and rubble.
Xu Mujun led a hundred thousand iron cavalry into Black Mountain Pass, engaging in street battles with the remaining soldiers of the pass.
In just half a day, after a night of fierce fighting, the soldiers of Great Yu finally took over Black Mountain Pass.
Of the five hundred thousand soldiers defending the pass, fewer than fifty thousand managed to escape.
The rest of the soldiers were either killed by the Thunderbolt, crushed under the collapsed buildings, or died in battle, with only a very small number captured as prisoners.
And for Great Yu in this battle, the number of casualties was just over ten thousand.
