Ouyang is not unaccustomed to observation while he trains. In his world, it was commonplace. Either his men were observing to learn something or the nobles to feel like they'd produced something glorious in him (or maybe they were just laughing at him under their breath, in spite of his successes. The oddity. The novelty). Here, at least, when people watch him, it's only skill they see. His reputation did not follow him (though it huants him), but he fears that it will inevitably inspire the same sort of othering he felt in his homeworld if (when?) it's revealed.

Those thoughts only prompt him to train hard. To be stronger. More fierce.

The poor dummy really doesn't stand a chance.

But part of Ouyang's prowess on the battlefield lies in his awareness of what's going on around him. He knows someone is watching. He's aware that someone is moving closer. When he finally pauses, he turns to the stranger, sword still in hand.

"Do you wish to fight?"
