Tremble! Even Breathing Makes Me Stronger!

[Feel-good power fantasy] Jiang Ming transmigrates to another world, bringing along a System he built himself. Since he made it himself, of course he can make it as satisfying as he likes. Don’t want to cultivate? Easy. Just breathing will make you stronger. Want to do a little cultivation? No problem. Every session will give you supercharged gains, so one day of training is like a year for anyone else. Don’t want to cultivate, and would rather start a side hustle? That works too. Learn alchemy or artifact forging in a flash, graduate in three days, and become a master in ten. As long as Jiang Ming wants to, he can easily reach the pinnacle of anything he does. “I only meant to put in a little effort, but somehow I ended up invincible.”
