In that battle, Ji Xinghe wielded such dual blades.
The past didn't fade into smoke, but became the Cutting Heart Blade. It sliced at every Imperial Mecha that could see Ji Xinghe, cutting into the heart of the Apes within them.
Charge.
Facing the encirclement, Ji Xinghe didn't choose to sit still. As he pulled out his blades, he began his charge, targetting the Viscount Level Imperial Mecha he had just taken down with his spear.
When this leading Imperial Mecha was pierced, it fell forward. However, the spear was still stuck in its body, stopping it from collapsing completely, leaving it kneeling on the ground supported by the spear's shaft.
Its body obstructed the charging momentum of the Imperial Mechas behind it.
The spear piercing through its body affected the morale of all nearby Imperial Mechas.
How could these Imperial Apes ignore the tungsten gold spear that had destroyed thousands of Imperial Mechas under Ji Xinghe's command?
