Learn one small skill every day

Every day at midnight, Bai Miao can draw a skill once.
The skills are completely random and flashy.
So he mastered a series of tricks such as somersaults, biting a lighter with his mouth, eating instant noodles through his nostrils, and drinking water through his eyes.
I originally thought these were skills that were more for show than practical use.
Until one day, Bai Miao received an email from the future.
What? My skills can be incredibly effective in death dungeons? And I can even learn local ruthless techniques in dungeons?
"Learning has no end; I just know a little more than you all..."
"You're talking about time stopping? That's actually technology; we should believe in science."
