Dragon Nine's is almost gone, Dragon Three's has less than one-fifth left, Sun Yiyi and Chu Xianling have less than a quarter left, Coach Xu and Song Xiaodong each have half remaining.
Coach Xu glanced at the reading on Song Xiaodong's tank and said with some admiration, "Oh, not bad, have you learned diving?"
"Well, learned a little." Song Xiaodong nodded.
"Quite modest." Xu Duoduo didn't ask further.
She was well aware that a 15-liter tank allowing 60-min dive time is the level of a professional diver.
Of course, Song Xiaodong wasn't a professional diver, just learned some diving, plus he was a Qi Refining Master.
"Everyone performed well; this is already good for a first time."
"However, when we dive, we haven't done anything, which represents oxygen consumption in a static state. If you were doing salvage or engineering repairs, you'd be working underwater, and with activity, oxygen consumption is three times the normal rate, shortening your dive time."
