When people are in critical moments, they always feel that time passes quickly. Zhang Yu now has this feeling. The extreme hypoxia makes Zhang Yu's head seem to be whistling continuously, and his heart is beating rapidly, as if he will jump out of his chest at any time.

"Puff!" Finally, Zhang Yu, who couldn't find a gap to breathe, could not hold on anymore. The turbid air in his mouth suddenly turned into a large number of bubbles and sprayed out from Zhang Yu's mouth. As the turbid air was sprayed out, Zhang Yu, who was originally extremely uncomfortable, finally felt a temporary relief. However, Zhang Yu was not happy at all, because Zhang Yu knew that he was finished. Unless he didn't breathe, as long as he breathed, the water entered his lungs through his nostrils, he could only stay in this cave forever.

Do you know what it can do? Even though he felt that he had already reached the limit, he insisted on swimming in the water for several seconds, but the excessive lack of oxygen made him unable to hold on any longer. He felt relieved and Zhang Yu had given up. Unexpectedly, he didn't even fall to death, but finally drowned in this dark cave. Looking at the little fish swimming around, which were like a rainbow under the light spots, Zhang Yu knew that it would not take long to become a bone in the cave, right? For no reason, Zhang Yu actually envied those little fish. If he could travel freely in the water like those little fish, how much would it be?

"Guru..." stared at the little fish that looked very beautiful, and a few bubbles spit out from Zhang Yu's mouth. Zhang Yu knew that he would die this time, but Zhang Yu didn't care about these things. Looking at two of the little fish that were very close to him, Zhang Yu gently reached out and touched them. What surprised Zhang Yu was slightly surprised was that this little fish should be afraid of people. It was already strange to dare to stop at a distance of only one hand from him. But when his hand touched the little fish, the little fish had no intention of dodging. Until Zhang Yu's hand touched its body, the little fish swam quickly with its tail...

‘No!’ Zhang Yu stared at the little fish until the little fish left, and then Zhang Yu took his gaze from the little fish, but at that moment, Zhang Yu was stunned. Aren’t he holding his breath? Didn’t he be able to hold it in? He just felt that he was going to be finished, and he couldn’t hold it in his nose. It was because of him that he was nervous but touched the little fish that looked pretty. But after these few seconds, he not only persisted and said nothing, but the feeling of depression in his body was relieved a little...?

This is, I accidentally broke through my body's limit? So I could hold it in for a longer time? No matter how many years did, Zhang Yu leaned forward and swam quickly in the water. Although I didn't know how long this thought that the limit breakthrough would last, since there was such a glimmer of hope, Zhang Yu must have grasped it.

Once his body began to exercise vigorously, the feeling of depression seemed to increase a lot. However, what surprised Zhang Yu slightly was that as he swam, something seemed to appear in his body for no reason. It quickly relieved the feeling of depression in his heart, and the next thing that actually surprised Zhang Yu.

As he felt the existence of that power, the feeling of depression began to disappear quickly. After a while, the feeling of holding his breath completely disappeared. Zhang Yu felt that he seemed to have absorbed enough air, and his body had no more discomfort. This made Zhang Yu a little stunned, but more of it was a surprise. No matter what the reason was, wouldn't it be better if he could keep in this state and swim here?

Next, Zhang Yu was shocked, but only shocked. How long is the cave? 5,000 meters? 8,000 meters? Before, Zhang Yu was swimming in the water in seconds. But after the feeling of depression disappeared more than an hour ago, Zhang Yu had been swimming in the water in shock for more than an hour. Whether it was the time to hold his breath or his strong and excessive physical strength, Zhang Yu felt strange.

Swimming in the water for more than an hour? You must know that Yu Yong is definitely one of the most physically tiring exercises. If you swim with all your strength like this, let alone for more than an hour, I am afraid that I can hold on for ten minutes without even realizing that I can hold on to it. But now, not only has I been holding my breath under the water for more than an hour, but also swim vigorously for more than an hour?

Thinking of himself falling into the hole from the mountain, and when he woke up, he found that nothing happened. Zhang Yu knew that something must have happened to him, but he didn't know it. Is he considered that he had some kind of supernatural power now? Can he breathe under the water? While excited, Zhang Yu was slightly scared. Perhaps because of an orphan, Zhang Yu always liked to think about something bad first. It was really good that he suddenly had such a skill, but what if someone knew about it?

Although his head was constantly thinking, Zhang Yu's hand did not stop. Finally, after swimming for more than ten minutes, a hint of whiteness finally appeared in the distance, which made Zhang Yu feel very happy. Nothing else matters now, but the most important thing is that he seems to have escaped now.

"Huh!" Is this really the case? Zhang Yu, who was overjoyed, accelerated his swimming speed, as if he was trying to make all the energy to eat. In less than two minutes, Zhang Yu finally swam out of the exit of the cave and saw the light coming from the outside of the cave. Zhang Yu was very glad at this moment. Fortunately, he had the ability to hold his breath in the water for so long. Fortunately, there was no landslide in this cave. Fortunately, there was no dangerous thing in this cave, otherwise how could he appear here now? He quickly drilled towards the water surface and drilled his head out of the water surface. Even if there was no feeling of holding his breath, Zhang Yu still breathed heavily, but the breath had just spit out a trace of it from his mouth, but it was stuck in Zhang Yu's mouth again.

"Boom boom boom boom..." There was a not huge waterfall twenty or thirty meters away from Zhang Yu. The waterfall looked like a drop of about ten meters high, so even if the waterfall was not too big, the sound of water was very loud. However, Zhang Yu had no intention of paying attention to these things at this moment. The place where Zhang Yu was was a pond with a diameter of more than ten meters formed by the water flow of the waterfall. Because the water flow was not large, the water in the pond looked very calm and could not see any flow. On the edge of the pond opposite Zhang Yu, four creatures that made Zhang Yu feel fear were all raising their heads to look at Zhang Yu, the uninvited guest who suddenly came out of the water.
