Although it is only the physical quality that has reached the level of a Qi Refining to Gang Level Martial Artist, this degree of physical quality alone is already comparable to most elite veteran soldiers.
It's important to know that even if one has studied Inner Qi, if they do not use Inner Qi to enhance their body during a battle, a direct hit by an arrow with Inner Qi Manifestation can be fatal.
After all, it's still a flesh body, not a steel plate. Even at Dian Wei's level, getting hit by dozens can still be manageable, but if there are too many, one could still get shot to death. The body's strength mostly relies on energy support, it's just that Dian Wei's body enhancement allows for better energy utilization.
Generally speaking, the body with Inner Qi Manifestation is much stronger than most Qi Refining to Gang bodies, and the body of Qi Refining to Gang is basically stronger than Martial Artists with Inner Qi Refinement.
