The fist broke.

No, to be more precise, it was the wrist that broke. The entire fist of the Undying Emperor maintained a clenched fist pose, but it was torn apart irregularly from the wrist by a tremendous force and fell to the ground.

Clearly, even this fist felt helpless.

After all, the target it was required to strike exceeded its capabilities, bearing a weight that a fist should not bear.
