The greatest difference between an Overlord Body Realm Martial Artist and an Internal Breath Realm Martial Artist was that an Internal Breath Realm Martial Artist could mobilize his Internal Breath to his entire body at will and easily unleash a huge power with his external cultivation moves. Under normal circumstances, his strength would naturally far surpass an Overlord Body Realm Martial Artist.
Although Overlord Body Martial Artists could also mobilize their Internal Breath, they either cultivated a special Internal Breath cultivation method and could casually mobilize their Internal Breath at the Overlord Body Realm or relied on the special external martial technique, the Hong Clan's Long Fist, like Chu Nan, to complement their powerful data ability and perfectly fuse the trajectory of their Internal Breath and fist technique to achieve the effect of fusing their Internal Breath into their moves.
