He didn't even wait for the skeleton to manifest all the way before throwing a punch with nearly all his strength behind it. The air moaned and the space lightly rippled as it went straight through the skeleton as if it wasn't even there.
At the same time the skeleton swung his way but Hao Xuan weaved out of its path. Unfortunately, the air pressure created by their combined attacks sucked him in right as the second bony fist came at his face.
Hao Xuan pulled back as much as he could but there was no way to avoid it completely. So he channeled some chaos Qi into his arm to create a shield that could absorb the damage.
The skeletal fist landed and the shield of Chaos Qi burst apart as it was made from paper. It continued forward and slammed into Hao Xuan's chest with almost half its previous strength.
