Jin Guangyao takes in each of Palamedes' movements as he prepares his demonstration with the attentiveness of a pupil who has every intention of doing both the assigned and supplemental course readings once class is over. He's very diligent. His eyes widen an appreciable fraction when he glimpses that flicker in the air around Palamedes' palm, and at his gesture he steps forward to reach out with one hand, delicately tracing his fingertips over the air.

He startles when he feels a wall, and then promptly smiles, a rare and delighted expression absent of any artifice. He's quick to shutter most of the enthusiasm behind something more appropriately mild-mannered, of course, before he notices the blood. At that he becomes much more practical, and fetches a simple handkerchief out of his sleeves to offer it out to Palamedes. (He's helpful that way.)

"Palamedes-xiansheng's work is impressive," he compliments him sincerely. "This 'ward' resembles barriers that can be created via spirit arrays, where I am from, though to be able to wield something like this while in martial combat would be..." One can almost see the gears and cogs at work behind his eyes, as though he is disassembling and reassembling all manner of ways that this technique could have changed the past--perhaps his own.
