I'm a Teacher in Konoha

Do you know what kind of ninja I want to teach? To be the most fierce, to be tough without giving in, to fight at the shadow level, to be able to use ninjutsu without forming seals, to open the eight gates at will, and to perform illusions in the blink of an eye. When you meet an enemy, no matter whether you fight or not, just yell, "Die to me!" He looks like an authentic Konoha powerhouse, so he is very dignified! What about psychics, forbidden arts, resurrection, you can learn everything you can from me. It doesn't matter if your qualifications are not good, just go up and give me a try. If they really can't beat me, I'll try to evade them, and I'll scare them to death. You ask me what level of ninjutsu is it? Regardless of whether it explodes or not, there will be a hole of at least 400 square meters on the ground. If you can only fight an elite Jonin, don't tell the outside world that I taught you the ninja. My purpose in teaching students is just one sentence. Don't seek the best, but seek the toughest!
