The emerald green plunge basin may

The emerald green plunge basin may look green on the surface, but it had an unimaginable depth. Yi Yun had previously tried exploring its depths but had never managed to dive to the bottom.

After submerging himself at about a depth of ten meters, he felt his ears hurting.

Human ears were extremely vulnerable. The most unbearable pressure a diver experiences came from his ears. Martial artists were no different.

As a person goes deeper, his eardrums will rupture before his organs could feel the pressure. Yi Yun blew up the air in his mouth. By increasing the pressure from his mouth, he could balance the external pressure surge, reducing the pain in his eardrums.

After diving to an unknown depth, Yi Yun experienced poor light conditions underwater. Only by looking towards the water surface would he see the beautiful sunshine being transmitted down.

In order to have a means of escaping danger, Yi Yun kept close to the cliff. Peppering the cliff were weird rocks. The rocks led downwards into a deeper depth that was complete darkness. It was a terrifying and bottomless darkness.

Thankfully, Yi Yun had reached the Vigor realm; his breaths could last him a long while. With one breath, he was able to endure about fifteen minutes.

On Earth, the breath holding record underwater was about thirteen minutes. Of course, those people had undergone professional training, and if Yi Yun trained himself more, his timing would be longer.

As the pressure increased, Yi Yun felt his lungs being compressed. His abdominal cavity was filled with bodily fluids.

The ribs enclosing his lungs were under immense pressure. It was as if a huge bear was stepping on his chest. Yi Yun even heard the creaking sound of his ribs.

If not for the bone training he had just completed, Yi Yun’s ribs would most definitely have broken.

With his abdominal cavity compressed, tremendous pressure was transferred to Yi Yun’s body, compressing his bodily fluids and organs.

Slowly, Yi Yun felt his limit approaching.

Diving was a dangerous sport. The moment one lost consciousness due to the water pressure, one was undoubtedly doomed. The corpse would slowly fall to the bottom and get completely crushed.

On Earth, deep diving enthusiasts had to make all sorts of preparations such as ropes, balloons and other life-saving devices.

As for Yi Yun, he naturally had none of that. He had to rely on his own assessments.

“Splash! Splash!”

In the quiet depths underwater, Yi Yun could hear his own heartbeat and even the sound of his blood flowing.

The sunlight in the mountains was already dimmer, but at these deep depths, one could say that Yi Yun was totally surrounded by darkness. Under a quiet, dark and high-pressure environment, the only thing that Yi Yun could clearly feel was the Purple Crystal Origins in his chest. That cool feeling flowed through his bloodstream.

This cool feeling was like the fountain of life in fairy tales. Although it was extremely weak, it could ensure Yi Yun’s survivability. It allowed Yi Yun to stay conscious under such extreme conditions.

This situation resembled the time he experienced the cave-in back on Earth. Trapped under the earth, the Purple Crystal had accompanied him in that quiet and dark environment.

Yi Yun also felt that the Purple Crystal was like his life’s last refuge. When his organs were damaged under the immense water pressure, the Purple Crystal would silently repair his organs. It allowed him to not only experience the immense water pressure but also recover in the shortest time possible.

Yi Yun lost his sense of time underwater. He kept following the theories of “Dragon Rib Tiger Bone Fist” by circulating his energies. When he felt his breath was mostly used up, he began to swim upwards.

Deep-sea divers would usually not have much energy or air. As swimming upwards consumed a lot of energy, most people on Earth used devices like balloons to propel their bodies upwards, but Yi Yun had to rely on himself.
