After taking a few deep breaths, he was ready to start his first dive.

Because the system requires him to dive unequipped, he doesn't carry any equipment other than a pair of swimming trunks.

Guan Lang plunged into the water, his hands brushed aside the body of water, and his body continued to sink slowly in the deep ocean with movement and gravity.

The water slid smoothly across his skin, and his body was cold.

Guan Lang stared at the progress of the system's task, checking the depth of his real-time dive.

“【5/300m】”

“【10/300m】”

“【20/300m】”

There were basically no obstacles in the early stage, and he quickly dived beyond the depth of the previous practice.

It may be that he is now in the deep water away from the shore, and the underwater world scenery is not good, only a watery blue.

In the distance, you can see a school of small silver fish swimming quickly.

Although the ocean is full of life, the sea is also vast, and the scenery seems to be particularly lonely.

Guan Lang looked at the underwater scenery of the deep sea area, and still dived like a dexterous fish.

The red hedron scales on his forearm began to glow faintly, and the gurgling bubbles slowly bubbled out, and a faint cool sensation came from the scales on his arm.

These magical little crystals are like the "respiratory organs" that grow on the surface of his body, and every time he squeezes out the bubbles, the feeling of lack of oxygen in his body will be relieved a little.

The webbing between his fingers slowly opened, giving him a faster dive speed.

The sea water is becoming deep and dark, and Guan Lang is in a state of diving down with a probe at this time, and he can only see the deeper and deeper sea below, like an abyss.

Behind it is the rays of the sun cast on the surface of the sea, which are getting farther and farther away.

This kind of psychological feeling of constantly diving into the darkness is quite bad, especially since he is alone in the vast sea at this time.

“【70/300m】”

“【75/300m】”

The deeper Guan Lang swam, the slower the dive.

He could gradually feel the pressure of the ubiquitous bodies of water around him from all directions, and the movement of his arms consumed much more energy than before.

With such a depth of the sea, it can be said that the vast majority of people in the world will never be able to stay in this place for the rest of their lives.

At this time, the base of his tongue is on the top, and he still has a breath in his mouth, and his nasal cavity and esophagus almost lock the breath, all in order to create a closed air cavity to regulate the pressure in his ears.

But even so, he still felt a lot of pressure in his ears.

Sure enough, the task was very difficult.

“【130/300m】”

“【135/300m】”

At this point, he should have surpassed the average human freediving record.

Guan Lang glanced at the crystal scales on his forearm, and saw that the fluorescence on it was much brighter than before, from a dull pale pink to a bright pink, and the rate of bubbles was nearly doubled.

Although the state of his body is not too uncomfortable because he is in a state of synergy with Begonia at this time, the strangeness of the fish-shaped characteristics on the body surface still gives him a great sense of urgency.

Although the speed of the dive was only 300 meters, he had to have enough time to surface in addition to diving.

And for him, whose weight density is much greater than that of ordinary people, the physical energy required to ascend may be even more terrifying than diving.

Guan Lang increased his strength again, whipping the soles of his feet in the back to push the water body like a machine.

With a wave of water close to a meter behind him, he was able to dive as fast as a plumb hammer in the water with the sudden increase in propulsion.

“【200/300m】”

“【210/300m】”

It's hard to perceive much light in these waters with the naked eye.

Guan Lang's palms, which were falling rapidly, suddenly touched an uneven hardness.

His body spun deftly in the water, his feet on a dark green reef.

It's not good, it seems to be the end.

The progress of the system task is stuck at 216m.

The depth of the sea was even shallower than he had imagined, and he thought he was far enough away from land.

It stands to reason that the underwater topography of the South China Sea near Qiong Province should be much steeper than the slope of the offshore continental shelf in other seas such as the East China Sea.

Taking the East China Sea as an example, the vast majority of the sea area may be 200 kilometers offshore before the water depth reaches 200 meters, but in the waters near Qiong Province and Guangdong Province, the water depth can reach tens of meters to thousands of meters, even in the waters close to the continental shelf.

He probably checked the depth distribution of the sea area before diving, and the area where he swam in this direction should be a deep area.

Maybe it's because he's swimming crookedly.

Guan Lang was a little depressed, although he didn't expect to successfully complete the task on the first attempt, but his original plan was to dive at least two hundred and sixty meters or even deeper.

At this point, it shouldn't be his limit.

But then I looked at the surroundings in a very faint light, and at least the ones that weren't swallowed up by darkness were the reefs with dense holes.

There should be no possibility of going deeper into the sea.

As for the farther away, Guan Lang couldn't see clearly, the underwater world was not only dimly lit, but also had all kinds of turbid small particles, and the visibility was extremely low.

That is, his eyeballs have a strength beyond ordinary people, otherwise it would be difficult for ordinary people to just stay here.

Shaking his body, the water temperature in the sea here is extremely low, it should only be a few degrees Celsius, and it is not suitable to stay for a long time.

Limited by external factors, Guan Lang had no choice but to continue even if he wanted to, his feet stepped on the reef, and his body began to slowly swim towards the top of his head.

The webbing between Guan Lang's fingers stretched to the maximum, and his body was also going upstream under the action of brute force.

He prefers the feeling of floating, a sense of sacredness that gradually enters the light.

“【115/300m】”

By this time, the hedron scales on his arm had turned bright red.

But it should be too late, mainly because this is his first time diving deeply, and he has encountered a lot of conditions, so he wasted some extra time.

Guan Lang was not too nervous, although the diaphragm in his body had begun to hurt slightly, but now he has more diving experience, and his grasp of the body is still relatively accurate.

Just when Guan Lang judged that the problem was not big, a large swarm of small silver fish like a swarm of bees or a storm swept over his head.

Of course, this is not the point, the point is that Guan Lang also saw a big guy with bared teeth and grinning among the fish, and at this time he was rushing to kill among the fish, and bursts of scarlet spread in the sea.

It is a fully fledged stout mako shark, 3-4 meters long, and its stance of rampage through the water is like a Mercedes car.
