Previous page        Return to Catalog        Next page

    For a moment, Qiao Hua's vision suddenly became blurry.  The pressure around him became stronger and stronger. Qiao Hua felt that every part of his body, from the organs in his chest to the joints of his limbs, seemed to be slightly deformed by the pressure.  Even with the swelling pain in his eyes, the light that Qiao Hua's eyes could see gradually became dimmer, and the bright spots formed by the sun above his head were weirdly distorted into various shapes, which was terrifying.  This dwarf tyrannosaurus had no choice but to close its eyes and rely on its hearing to perceive things around it.  Just now, all Qiao Hua's attention was focused on what he saw. After closing his eyes at this time, he realized that his ears had been occupied by a strange sound similar to metal friction. His originally sensitive hearing was basically no longer there.  It has no effect anymore.  Based on these strange feelings in his body, Qiao Hua knew that he had basically reached the limit of his ability to dive so far, so he had no choice but to slowly float towards the surface of the sea.  The speed of upward floating is even slower than the speed of diving.  Although this dwarf tyrannosaurus didn't know much about diving, he also knew the horror of things like decompression sickness.  Under water, every time you dive about ten meters, the pressure will increase by one atmosphere, and the amount of gas dissolved in the blood will increase accordingly.  If you float too fast during diving, the inert gas in the body will be separated from the blood and exist in the blood vessels and other tissues in the form of bubbles, destroying body functions and causing life-threatening consequences if you are not careful.  Qiao Hua doesn’t know how many meters he has dived so far, but the dark environment and strong pressure around him indicate that he has gone deep enough this time.  Because there is no suitable reference object underwater, it is difficult for Qiao Hua to accurately judge the speed of his ascent visually.  Fortunately, his extremely keen perception plays a huge role at this time. Qiao Hua can judge whether his floating speed is appropriate through the slight difference in pressure felt by his head and hind limbs, and make appropriate adjustments.  After a long time, Qiao Hua finally felt that the strange noise in his ears gradually disappeared, so he opened his eyes and found that there was some light around him again.  The long, rootless aquatic plants and the colorful and strange-looking fish that we had just seen all seemed particularly kind to this dwarf tyrannosaurus.  In the deep sea, after experiencing a strong sense of loneliness and fear in his heart, he truly felt the value of light and warmth.  But just as he was slowly rising and observing the various creatures around him with interest, the tightening feeling from his lungs made him come back to his senses from the beautiful scenery.  It has been more than an hour since we entered the water.  The air stored in the body has been recycled again and again, and almost all the oxygen has been consumed.  Qiao Hua couldn't help but become nervous, and thousands of grass and mud horses roared past in his heart.  Thinking about it, when I was in the depths of the ocean, I consumed too much oxygen due to fear, and now I am not so nervous. In the final analysis, it is still the fault of not being strong enough mentally.  After forcing himself to calm down, the dwarf tyrannosaurus, while minimizing the remaining oxygen consumption in the body, let go of the tree vine tied to the big stone in its mouth, shook its legs and moved faster towards the sea.  Float away.  Although there are certain risks, Qiao Hua knows that returning to the sea is the most important thing at the moment.  If you run out of oxygen underwater, there will really be no way to survive.  The pressure felt on the body is constantly decreasing, but the temperature of the seawater in contact with the skin is getting higher and higher.  Qiao Hua knew that the distance to the sea was not far away.  When the last trace of oxygen was squeezed out by Qiao Hua, the dwarf tyrannosaurus suddenly rushed upward.  A gust of salty sea breeze hit his face. Qiao Hua immediately opened his respiratory tract and swam hard towards the shore without stopping for a moment.  But the moment it left the water, this body no longer seemed to belong to him.  Qiao Hua felt intense pain coming from all his joints, as if there were millions of ants biting his body.  From the heart to the lungs to other organs, all kinds of pain and congestion come one after another.  You don't need to guess to know that it was because he floated too fast in the last few dozen meters that the inert gas in his body formed bubbles, which was very serious.  Enduring the severe pain, Qiao Hua swam to the shallow sea not far from the beach.  When its hind limbs touched the soft sand at the bottom of the water, its vision suddenly became blurry.  He could still vaguely see the fruit core on the tree looking this way, but after only taking two or three steps that way, his vision went dark and he fainted completely.?????尼玛，这回可真要玩儿完了!????……????“啊呜啊呜——哧溜哧溜——”????“啊呜——哧溜哧溜——”????一阵叫声在乔华的身边响起。  This was the first time he heard this cry, but it was only this time that he finally had the strength to open his eyes.  What appeared in front of his eyes was a fuzzy little shadow, which kept yelling at him, accompanied by the sound of "chick, cheep," licking something, and a sense of warmth rising around his nose.  Although Qiao Hua's consciousness was still a little vague, he immediately guessed that this little thing must be bean paste.  Gradually, the sensory abilities throughout the body were restored to a certain extent.  An uncomfortable feeling mixed with soreness, numbness, swelling and pain came from all parts of the body like a tide, and Qiao Hua almost fainted again.  After about half an hour of recovery, the dwarf tyrannosaurus finally recovered from the severe pain.  Although there are still constant pains in various parts of the body, it is much better than at the beginning.  This phenomenon made Qiao Hua feel a little confused.  According to common sense, the bubbles formed by the accumulation of inert gas due to excessive decompression will not disappear automatically in a short period of time. However, within a short period of time after the formation of such bubbles, organisms will produce different symptoms depending on the severity of the situation.  Feelings: In mild cases, itching and pain may appear on the skin; in severe cases, organs may be blocked, leading to shock and death.  Based on what he felt before he fell into coma, Qiao Hua concluded that the bubbles formed by the inert gas in the body had affected various parts of the body, including internal organs.  I should have gone to see Gaia now, so how could I wake up?  “Ah wu——” Seeing Qiao Hua open his eyes, Doujiang finally stopped licking.  After letting out a low cry, the little guy began to circle around the body of the dwarf Tyrannosaurus, as if a doctor was checking the body.
