Fortunately, this trench generated a suction force, greatly reducing the upward buoyancy, giving the body a sensation akin to suspension.
In this way, Fang Cheng tensed his arms and shoulders amidst the surge, continuously stretching and descending.
After completing 50 repetitions, he continued to practice Hanging Leg Raises in the same manner.
Then, Back Bridge, Handstand Pushups, Push-ups, and other Prisoner’s Six Arts skills were deployed one by one to gradually test the training effects.
Once all movements were successfully completed in five sets, about an hour had gone by.
Possessing the talent of "Water Breathing," Fang Cheng could hold his breath underwater far beyond ordinary human limits.
Although he didn’t grow gills to filter and absorb oxygen directly from seawater like fish.
He still, like a whale, had an extremely efficient mode of breathing.
Whales are mammals that also rely on their lungs for breathing.
They have a large lung capacity, and their hemoglobin and myoglobin concentrations are higher than those of humans, enabling them to store oxygen within minutes and then maintain extended underwater activities.
For instance, an adult blue whale can breathe underwater for nearly 30 minutes, and a sperm whale can even hold its breath for two hours.
During the training, Fang Cheng never returned to the surface to exchange the air in his lungs.
Instead, he persistently continued the training, testing the limits of his abilities.
As his exercise increased, blood circulation accelerated, raising his body temperature.
Fang Cheng even faintly felt as if,
The pores all over his body seemed to also participate in breathing, drawing faint oxygen from the seawater.
However, while doing the sixth set of Push-ups,
He suddenly felt as if a heavy boulder pressed against his chest, making it difficult to breathe.
Immediately his heartbeat slowed, and his limbs started to weaken.
Realizing he was nearing his limit, Fang Cheng immediately exited the state of Concentration.
Then, holding his breath, he forcefully pushed against the seabed rocks with his feet, utilizing the buoyancy to control his rhythm as he slowly swam upwards.
As he neared the surface, the surrounding light brightened, the seawater gradually shed its dark hue, turning emerald clear.
The outside noises also became increasingly clamorous, the sound of bursting bubbles, the ripple of swimming fish schools, exceptionally clear.
Until bursting through the rippling surface of the sea, all scenery and sounds amplified several times, as if returning to a world filled with dynamic, moving light and shadows.
A large flock of seagulls circled overhead, emitting clear cries.
The noisy tide, along with the bird calls, resonated, one after another.
Fang Cheng took a deep breath of fresh air, relishing the liberating exhilaration from extreme pressure to freedom.
In front of him, the azure sky, towering Cape, and a shimmering panel emerged.
[Concentration Experience +3]
[Push-up Experience +36]
[Deep Squat Experience +32]
[Lifting Leg Experience +21]
[Pull-up Experience +23]
[Back Bridge Experience +20]
[Handstand Pushups Experience +27]
Looking at the experience points gained from this underwater weight training,
Fang Cheng wiped his wet face and hair, displaying a relieved smile.
Especially the progress in Push-ups was notably impressive.
[Push-ups lv2 (347/500)]
With this efficiency, it will only take a few days to smoothly advance to LV3 Grandmaster Level.
The efficiency was so high, it felt like going back to the initial stages of training, or even far surpassing it.
And another advantage, it completely prevents outsiders from prying.
Feeling the tiredness from the change in air pressure in his body, Fang Cheng looked up at the position of the rising sun.
It was already noon, not planning to dive back to continue training.
"Let’s come back tomorrow."
Fang Cheng muttered softly, a new idea forming in his mind.
Next time, he might try practicing Pile Skill and Breathing Technique underwater.
