Notice that most of the first year students who are soloing these things are in fact already trained warriors.

Tai Yang, for example, is a 21 year old warrior monk wuxai hero. Also, his target couldn't fight back.

Deja is a blind samurai with superpowers. Bit younger at 17, but probably still fought a few good fights.

Both very much trained warriors.

I am kind of wondering how Aurora is doing all the things she's doing while unconscious.
