The addition of two new heads, though not very smart, was also a good thing, they completely obeyed the commands of the main head without any trace of resistance.

He then made the copper corpse move its arms, and initially, the six arms seemed somewhat awkward for it to handle.
Fortunately, the four new arms were controlled by the two new heads, and after some time getting used to them, the copper corpse could now manipulate all six arms with ease.
Here it must be mentioned that the copper corpse's innate combat instinct made it born for battle, whether naturally occurring or refined by cultivators, fighting was their purpose for existence.
Not to mention having three heads and six arms, even if given a more bizarre body, it could quickly utilize it and turn it into a weapon for combat.
