"but…..since I return back home, even if there is a tough fight, even if there was a few times that I almost get beaten, I never truly reached a point where I was exhausted out of all options"

It is his way of saying that since the time he acquired the flute, he never reached a point where his method is exhausted.

If he was arrogant person, it means he has tens of thousands of methods.

But how could Azief be arrogant when he knows there is so many beings in the Omniverse that is far stronger than him and each of their method is more deadly than the other

The only reason why he never reached such a point is because he knows when to fight and also because the protection of fate and destiny

That and also because of his Perfect Foundation.
