I think chapter title is actually" immortal device/tool appears in the world" or something and rather than air machine "qi mechanism" (qiji) a concept that has to do with Chinese medicine i think.....and the blurb should be something along the lines "qiji/qi mechanism: the overflowing scent of the immortal device/tool breath/aura? can only be detected/"perceived by someone with supreme talent" the are a few other small issues...
