The mc could discover a new form of cultivation, such as body cultivation, not necessarily invent it can only discover the abode of a sword cultivator who tried to create a way to cultivate and it may be like the rebreathing techniques of demon slayer The stages would be the same only it would be more difficult to improve without effort and resources this can be good for the clan as well because it ignores the necessity of the martial spirit you can also replace the necessity of spiritual rings with blood or something else Translated with Google Translate
