Hogwarts' Arcane Mechanist Sword Immortal

The Mechanist mechanic was already a good point, but then they inexplicably had to come up with flying swords. Does simply putting a sword in the air make it a flying sword? Using the same principle, they could create flying needles or blades; wouldn't those be far more lethal than a flying sword?

I'm not nitpicking, but the protagonist's inexplicable pursuit of flying swords is fundamentally untenable in terms of character development. Even if he was some kind of sword immortal in his past life, I'd still find it odd; what is this? A disabled system plus some strange past life experiences leading to this conclusion is just baffling.

They say flying swords are cool, but they're not that great; firepower coverage is much better. Aren't floating cannons cooler than this?

Given these conditions and status, it's understandable that they wouldn't go to Houndhouse or Eaglehouse, or even Gryphonhouse, but Slytherinhouse is truly incomprehensible. And sure enough, conflict ensued, which is just speechless. If I were a wizard, I would definitely choose Houndhouse first—easy to make friends, and they even guard the kitchen.

In the world of cultivation, was the protagonist killed because of his mouth?

Why don't you just modify the wizarding system into a cultivation system? For example, they might call magic power "magical power," spells "spells," meditation "quiet contemplation," the pursuit of truth "cultivation," a magic broom "flying sword" or "somersault cloud," and a protective spell "golden light spell,"...

The main character seems a bit too saintly; he wants to help with everything!

You might as well exchange your ability for the magic of the Divine Awakener, Ryan Ames.
