Actually, MAs don't have stars, True Body Refining is something completely different from what MAs use. Martial Cultivation is fundamentally reliant entirely on TW's blood, no matter how hard someone works, If they don't have TW's blood, they just don't get any stronger. MA are bloodline users similar to beasts rather than true cultivaters. Only Dao is something that MAs and Cultivaters share. MA extract the body's essence to get stronger which actually degrades their potential for actual body refining.
Yeah I think TW explains (or used to before) that Body Refiners just infuse the Qi they gather into their flesh instead of keeping it in their Dantian, but they still have to gather the Qi, and as far as I am aware you need Meridians and a Dantian for that in any case.
