Chapter 1956 - 1851: Thoughts

Capítulo 1956: Chapter 1851: Thoughts

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.”

“Follow me.” Xu Duoduo led everyone to an equipment room.

“Each of you take a 50-meter weight.”

Song Xiaodong saw in a box in the equipment room, a pile of lead balls attached to buoys.

Song Xiaodong picked up one; it was very heavy.

“Check it, and drop it.” Xu Duoduo instructed.

Each person dropped a lead ball, it sank directly, with the buoy floating on top, the rope was 50 meters long.

“Dive down, bring the lead ball back up, pay attention to adjust your buoyancy as you ascend, use buoyancy to reduce your energy consumption, but also mind your speed, don’t rush.”

“Switch tanks, check your equipment, then check each other’s equipment.”

“Let’s check each other.” Xu Duoduo said to Song Xiaodong.

Sun Yiyi and Chu Xianling glanced sideways at Song Xiaodong while checking each other’s equipment.

Song Xiaodong pretended not to see the jealous looks from his wives.

“Alright, be careful while diving, don’t get tangled in the ropes, be cautious underwater of anything that can snag you.”

The group dove again.

This time they descended much faster, knowing the ascent would be very slow.

Soon the group reached 50 meters, with each lead ball suspended in the water by the rope.

Xu Duoduo directed everyone to hold the rope fastening the lead ball with one hand and slowly ascend.

The group adjusted their buoyancy devices independently, ascending bit by bit, being halted by Xu Duoduo if going too fast, and urged if too slow.

Weighted ascent was very difficult because by reaching 20m, the buoyancy value maxed out, but they couldn’t continue ascending.

As they got closer to the surface, underwater pressure decreased, reducing buoyancy, making the lead ball heavier.

The remaining 20m needed to be swum up with physical strength.

Song Xiaodong moved easily like a fish; Xu Duoduo, like a water snake, wove through the group, checking their conditions.

Everyone gradually mastered using True Qi to adapt to pressure, able to protect themselves by circulating True Qi despite large pressure changes, preventing decompression sickness from ascending too fast.

Song Xiaodong, Chu Xianling, and Sun Yiyi successfully surfaced; Dragon Three and Dragon Six were ordered by Xu Duoduo to let go due to insufficient oxygen.

Everyone surfaced and went ashore, Xu Duoduo checked everyone’s tank readings again.

Xu Duoduo and Song Xiaodong had a quarter left, Chu Xianling and Sun Yiyi had less than a quarter, Dragon Three and Dragon Six’s oxygen was depleted.

“Not bad, not bad, you must know some breath control techniques, this greatly increases your chance of surfacing alive.” Xu Duoduo expressed satisfaction with the group.

“There are many ways to reduce oxygen consumption, including meditation, breath adjustment, and minimizing movement. Before diving you should breathe deeply, act gently during activity, and utilize buoyancy devices instead of swimming yourself when possible.”

“Of course, another important point is if you find you can’t bring something up, let go immediately.” Xu Duoduo looked at Dragon Three and Dragon Six, who had just failed their task.

Clearly, Xu Duoduo already knew they were probably attempting to salvage a wreck.

In the afternoon, they dived many more times, and after the last dive, Song Xiaodong’s remaining oxygen even exceeded Xu Duoduo’s.

Xu Duoduo looked dissatisfied as he gazed at Song Xiaodong’s tank reading.

“Wow, impressive, looks like you can dive longer than I can!” Xu Duoduo praised Song Xiaodong.

“You guys rest, come on, let’s compete again.” Xu Duoduo said to Song Xiaodong.

“Sure.” Song Xiaodong agreed gladly.

The two swapped tanks and checked each other’s equipment.

“Hey, Coach Xu, don’t you two get stubborn, don’t stay under for an hour, we’re starving!” Sun Yiyi called to Coach Xu.

“If you’re hungry, there’s a restaurant outside!” With that, Song Xiaodong and Xu Duoduo flipped over, splashing water on the surface.

“Hey——”

Song Xiaodong and Xu Duoduo dived again to fifty meters, focusing intently at that depth.

The underwater world had a silence unlike anywhere else, just a dim yellow hue and the pressure on the wetsuit, no distracting noise around.

This, is water.

At 50 meters underwater, Song Xiaodong finally understood Teacher Wang’s lesson.

Wang Xinyi said, scattered thoughts consume spirit; the method to eliminate distractions is focusing attention on a single thought that arises.
