If you ever wonder why shinobu fans gets a lot of shit it's because of this
People are being too comfortable larping demon slayer
First off not only does this person completely fail at basic biology, it's obvious they don't know how the human body works, so am gonna teach them
Total Concentration Breathing works by hyper-oxygenating your blood and increasing heart rate and circulation to give your muscles explosive speed which actually speeds up poison circulation, not slows it. You can't just dial down your blood flow without your blood pressure crashing and passing out from lack of oxygen to the brain.
You cannot consciously tell your smooth muscle tissue or cardiac muscle to slow down through simple thought. Heart rate and vascular constriction are regulated by the autonomic nervous system.
The only reason Tengen survived is because he explicitly used extreme muscle control to stop his heart entirely to freeze the poison's spread, a lethal, specialized trick that standard Total Concentration Breathing cannot do, as well as him having poison resistance. I mean most of y'all should know this basic info but apparently not all
And lastly, Muzan's blood/poison causes rapid cellular destruction, but it was actively being delayed and weakened by Tamayo's four-stage anti-demon drug injected into Muzan, while Gyutaro's poison is an instant kill lethal toxin with zero antidote available during the Entertainment District Arc.
If you haven't figured it by now am absolutely throwing shade at this user and their d**b argument but I didn't show their name so I didn't break any rule, it's not hard to so basic research instead of just larping
