The broadsword can be used, but against a swarm of rodents, its advantage isn't obvious.
Xia Hong pondered for a long time and finally thought of the Yi Blade, one of the four systems of Tang knives.
As the name suggests, the Yi Blade, due to its length and delicacy, initially symbolized solemnity and grandeur, and for a long time was used as a ceremonial implement for royal or important occasions, with little practical combat use.
However, during the Ming dynasty, a famous general combined the Yi Blade with the Long Spear, devising a method suitable for battlefield duels and flag captures, giving the Yi Blade practical combat value, reinvigorating this weapon.
The Yi Blade is best suited for charging into formations, opposing many foes with few, and due to its long blade, it has a wide attack range, making it highly effective against speed-type enemies.
