Sea bats have evolved huge claws on their lower limbs. These claws are extremely sharp, even larger than an eagle's claws. The claws can easily pierce thick fish skin and embed deeply into fish flesh. The broken body of the bull shark swaying in the water is the masterpiece of two sea bats.
Due to their extremely fast speed, the sea bats drag the shark carcass along the path leaving a scary red line. We are less than one-third as fast as them, but we can continue to follow this red line.
Underwater exercise consumes a lot of oxygen and is also an important test of physical strength. I pray in my heart that this sea bat will never visit far away. It is best that its nest is nearby, otherwise it will be really desperate.
When following up crazily underwater, you need to constantly observe the surroundings, praying in your heart that other deep-sea monsters will not be attracted by the smell of blood too quickly.
We followed the trajectory of the sea bats and finally found this cave hidden on the seabed before the oxygen was about to run out.
The group of people all breathed in the air greedily, which was a sense of security that was far inferior to scuba diving.
But I soon discovered that the abnormal pressure in this cave was very uncomfortable. We breathed in the surrounding air for a long time without getting the satisfaction of oxygen. This is very similar to altitude sickness. There is absolutely nothing wrong with this feeling of lack of oxygen!
This made me realize that although there is air in this cave, it is thin air. Perhaps the sea bats living here have already adapted, but for us humans from the land, it may be a disaster.
No one expected that altitude sickness, which can only be encountered at extremely high altitudes, would actually happen to us at the bottom of the sea.
Natural selection. When I looked at the sea bat's huge and closable nostrils, I already had the answer in my mind.
Just like the Sherpas, who are known as the perpetual motion machines on the high mountains of ice and snow, they have evolved wide nostrils and strong hearts, and can walk on the Everest mountain range as if on flat ground. This is out of reach for ordinary people, but This is a survival skill that Sherpas are born with.
The seawater where we are is still pouring in a little bit. The fat man has a large lung capacity and a large demand for oxygen. His face is slightly blue, and the feeling of suffocation must be stronger for him.
I dragged the fat man away from the sea water and poured it into his mouth. He groaned: "Cao, this is really weird. Why does it feel like a vacuum has been sucked out? His grandma's body feels really uncomfortable... Logically speaking, Fatty's physique shouldn't be..."
I asked him to talk less. There was insufficient oxygen. No matter how bad the environment was, it was better than drowning in the sea. Although this cave was not a place to stay for a long time, the method of escape must be worked out from here.
This cave is like an inverted bottle, very spacious. Two sea bats not far away had already started eating. They showed no intention of taking precautions against us uninvited guests, which was indeed beyond everyone's expectations.
Professor Yin was an old man. This adventure really cost him half his life. Lin Qi kept stroking his chest to help him breathe. Seeing that the effect was not good, Lin Qi had to give the professor some of the remaining oxygen. . Put on the breathing valve. After taking a few deep breaths of pure oxygen, Professor Yin gradually calmed down and his body no longer trembled violently. He knew that there was not much oxygen left, so he just took a few breaths and quickly asked Lin Qi to turn it off to save it for later use.
Lin Qi watched as the oxygen valve was re-closed. He swallowed hard. He also felt uncomfortable. It could be seen that he was eager to take a few breaths of oxygen.
Two sea bats tore the bull shark into pieces. One of them made a harsh sound, and a response came from the depths of the cave. It seemed that these two were hunters of the group.
The living habits of various biological groups are very different. Take lions and wolves as an example. Most of the time, female lions hunt in groups, and only rarely do male lions take action. The wolves go out in full force to surround and drive away the prey, leaving the prey with nowhere to go. . One thing this type of population has in common is that the enjoyment of prey is strictly hierarchical. The wolf king is in charge of command and takes the lead in enjoying the food. After the wolf king has finished eating, the wolves at the next level continue to enjoy the food.
I watched these two sea bats feasting for a long time. It seemed that they had broken away from this strict hierarchy, and there was a strong tendency that whoever contributed the most would enjoy first.
I couldn't figure out their habits for a while, but I only heard the response from the depths of Haiyan Cave getting closer and closer. There was nowhere to hide now, and I might cause trouble when a large number of sea bats arrived.
The place we were in was very useless at the moment. The thin air made people more and more lethargic. Without paying attention, two small bats had flown over from the depths of Haiyan Cave. Their bodies were covered in purple, and their hearts could clearly be seen beating.
This scene is very strange. Two purple sea bats are as big as pigeons. The skin on their chests is as thin as cicada wings. Every time the heart beats, you can clearly see it.
No one knows the true growth process of sea bats. They can only think that this little purple bat is their infant. There are countless creatures that undergo complete metamorphosis in nature. For example, a butterfly will go through three lives and a crawling insect can change. It flies with wings, so it is not unusual for this purple sea bat to turn black after forming.
Two little purple bats ate the heart of the bull shark, and then flew to the depths of the sea cave. The two hunters watched the little bats disappear, and suddenly turned around to look at us. They moved slowly over, their sharp bat claws scraping against the rocks. The sound coming from it was really creepy.
We came down in a hurry and lacked weapons and equipment. The water crossbow in my hand became the most convenient self-defense tool.
The fat man said nervously: "I'm afraid I'm tired of eating fish and want to taste human flesh. Fatty, I'm short of oxygen. If I attack at this time, my opponent will also win a disgraceful victory. It's really hard to win!"
I raised the water crossbow and slowly lowered it. I was getting closer. I still couldn't feel the murderous aura from the sea bats. They didn't seem to be interested in us, but wanted to re-enter the water.
Sure enough, the few of us tacitly moved out of the way, and the sea bat swaggered into the sea again.
I was very puzzled. This sea bat actually seemed to be raised by people. Not only was it not afraid of people, but it also seemed to have a... some kind of perception of people.
This feeling is very strange and strange, and I can't figure it out.
We just subconsciously touched our left chest, wondering if this magical thing would happen to us.
Seeing that the two sea bats disappeared and there was no movement at all, the fat man asked me if those two purple bats were a different species and were born with some kind of strange disease. In order to take care of these sick people, a special case was made to let them first Meal, and as the saying goes, what you eat is what you eat, leaving the heart, the strongest muscle, to them.
The more the fat man talked, the more he felt that he made sense. He took a few deep breaths, suppressing his face to turn red. He added: "Since the two little sick patients just finished eating and left, the next table will be here. It’s time for the seventh aunt and the eighth aunt. This place itself has little air and weak oxygen. If we don’t have enough oxygen, whoever is going to have a bad temper will eat us alive after saying hello.”
Professor Yin, who has always been proud and energetic, had gone through such a battle. He was probably a little confused after all the fuss just now. After being frightened by the fat man, he became anxious: "Comrade little fat, you can live for a while...here." The air is too thin, no less than the snowy tops of mountains."
Professor Yin took the oxygen mask from Lin Qi's hand and took a sip before continuing: "I have just passed through life and death, and now we are all our own. Uncle Yin, I have never boarded any waves or stepped on any ships. Only This is the first time I have encountered this hollow area under the sea, and now it seems that it is not a good thing. In short, it is not suitable to stay here for a long time!"
Two people had already backed down, but it was actually three people. After all, Professor Yin represented Lin Qi.
In this case, I immediately decided to go forward with Long Wu to investigate. After all, the escape route was not that easy. The oxygen problem alone meant that people had to be left behind.
The others were waiting in place. Long Wu and I walked around the bloody corpse of the bull shark and headed deeper into the sea cave. I very much hoped that the oxygen concentration inside would improve.
Later, it turned out that my choice was right. Not only did we not encounter other sea bats, but we also discovered a lot of murals. After seeing the murals, I finally let go. Since someone can paint here, it means that this sea cave is not simple. , there must be vitality hidden there.
Each of these murals is signed with the word "Xu Fu". His shocking plans are all displayed on the six murals. It turns out that all the people he brought have this condition, and the skin of the heart becomes very thin. The beating of the heart can be seen outside the body.
At that time, I suppressed my racing heart. I felt like I was just like the people on the mural. My heart was about to jump out of my body. At the same time, I found that the oxygen here was almost normal. Because I was so nervous just now, if according to the oxygen conditions at the entrance, I should have fainted from lack of oxygen.
Upon discovering this information, I asked Long Wu to stay here, and I immediately turned around to rescue the remaining team members.
Everyone came to the mural together. At this moment, people's faces were filled with the joy of surviving the disaster. After all, everyone knew in their hearts that if there was no way forward, the retreat would be the road to hell.
According to the instructions on the mural, this sea cave was originally the lair of the sharks. It turns out that this area is really like a bottle embedded in the sea. The sharks also need to breathe. They do not stay underwater forever. Due to tidal action, these ventilation holes can be used when the tide is low. Therefore, this sea cave has become a periodic oxygen-containing zone that can be recycled, which also explains why the distribution of oxygen in the entire area is uneven.
What is even more unexpected is that Xu Fu discovered this magical place in the dense sea through divination. In fact, Xu Fu was a real semi-immortal Taoist. In order to cover up the real secret he discovered, he asked the First Emperor to let the historians deliberately record that he was a Jianghu. fraud. Among the people sent by Xu Fu, Shilong followed, and then sent a fake person to pretend to be in the dynasty. Only then did Zhao Gao get a chance, otherwise the real Shilong was present, even if he was dying, his look would be enough to scare Zhao Gao to the point of kowtow. .
