how to get stone breathing in demon fall

One of the main issues like Mc has mastered all breathing techniques of demon slayer to the height yet every single time I mean in every time he only uses stone breathing and fire breathing he never uses thunder breathing or others it's so annoying too it Mc has soo many many interesting abnormal skills yet he never use instead he always use fire jutsu with flame breathing and stone breathing so so annoying that I want to beat the author why restrict Mc to use only two skills in every single fight I have read mtl so you guys will be disappointed if you know what I mean

Demon Slayer: Perverted Breathing Style.......................................................................................................................................................................... .

this is a really good book despite the fact that he rarely updates and I would recommend other people to read it. but now for what I want. I want the MC to fight All for One and to barely stand against All for One with All Might, basically being a severe detriment instead of a helping hand and for him to realize that and to give a speech about how he's lived a good life and that he doesn't mind dying younger than he would like just to get rid of All for One so he crosses his arms like the Stone Hashira did and unleash a Demon Slayer Mark that Amps his physical capabilities where he stands next to a weakend All Might taking on All for One toe to toe and basically doing his version of Tengen vs Gyutaru with him using either Sun Breathing or Stone Breathing along the Red Blade the Stone Hashira used in his fight against Upper Moon 1
