Lucy awoke first.
After waking up, she didn't rush to open her eyes, yet it was evident from her moving eyeballs, visible even with her eyelids closed. Then, her eyeballs stopped moving too.
Gao Yi found this very interesting, so he didn't make a sound but decided to observe what Lucy would do next.
Few could feign sleep in front of Gao Yi, and none could pretend to faint in his presence.
Because Gao Yi practiced Hsing Yi, Eight Trigram, Tai Chi, and even Heart Connect Technique, all of which ultimately involved breath control—it meant that anyone practicing these arts needed to heed every inhale and exhale.
So while others breathed unconsciously to survive, Gao Yi's breathing was a decades-long practice.
A master of Inner Boxing could simulate the breathing state of sleep, but a comatose person, having lost consciousness, could not consciously adjust their breathing.
