Chapter 518 Underwater Level

If we were on land, we would have to kill all the surrounding creatures one by one, but in the water, especially in closed waters like this, it is too easy to kill these fish.

Although there was no sound, the audience outside the glass tank saw a sudden flash of blue light in the water, and then all the piranhas suddenly began to twitch. About two seconds later, all the piranhas began to turn their bellies at the same time, and then floated towards the water. As for us, we sank to the bottom of the fish tank as if we didn't see the changes around us.

Because we are covered with metal armor and our bodies are different from humans, we will sink to the bottom very quickly if we don’t take the initiative to swim. But this place is just like this anyway, there is not much difference between floating and sinking.

In fact, this place is not really a closed fish tank, at least it is not a small fish tank.

The hole we just came down from is actually just an entrance, and the area we are in now is actually a passage surrounded by a one-meter-thick glass wall. The top and bottom of this channel are rocks, and only the two sides are glass. Outside the glass on both sides are two channels parallel to our underwater channel, so people on both sides can watch us in the glass channel. The only difference in action is that we are in the water and they are in the air.

This glass corridor is actually not always such a large space. For example, the place where we found the piranha was relatively open when we first came down. The distance between the glass walls on both sides was about eight meters. As we walked forward, the passage began to gradually narrow, and finally it became only three meters. Meter wide state.

Because there are a lot of lighting equipment in the waterway we are in, while the channels on both sides are relatively dark, and the water here is quite clear. Therefore, even if the area was more than eight meters wide before, it can still ensure that people on both sides can see each other clearly without being blocked by the isolation effect of the water. As for the current situation where it is only three meters wide, it is even more unusually clear. .

At first, because we lost those piranhas in an instant, the spectators around us didn’t pay attention to breathing for a while. However, after we walked in the channel like an underwater stroll for about five minutes. Suddenly someone reacted and asked the person next to him: "How long have they been down here?"

The person next to him was stunned for a moment, and then said as if he suddenly remembered something: "It's been at least three minutes."

"Then they...?"

The person next to him nodded and said silently: "It turns out that dragons can breathe underwater!"

"Maybe it's just that the breath holding time is longer." Another person said: "I heard that there are professionally trained people who can hold their breath underwater for eleven minutes. They are artificial people, and they must be stronger than humans. They should not be able to hold their breath for less than twenty minutes. question."

At this time, a woman said: "The case you mentioned of holding one's breath for eleven minutes was someone who lurked in the water and remained motionless for eleven minutes, but they were always moving. Is it normal for oxygen consumption to increase during exercise? So it’s impossible to stay closed for that long. If they can only stay closed underwater for less than eleven minutes, that means they have good breath-holding ability. If it exceeds this time, it means they must be able to breathe underwater.”

Just as the audience was guessing, a door suddenly appeared in the passage in front of us. There was no lock on the door, just a turn handle that opened easily. After opening the door, we got in, and then a prompt sounded in the water asking us to close the door first. Then go and open the other door ahead.

The space between these two doors is only a few square meters, almost the same as the space inside a slightly larger elevator. Because both doors are made of metal, we have no idea what is behind the front door, but we are sure it is dangerous.

Although we can't see it. But that doesn’t mean the audiences on both sides can’t see it. Although both doors are made of metal, you can't see the other side. But because there are glass on both sides, viewers outside can see what's going on behind the door.

In fact, the space behind the door is an open area that is gradually enlarging, and the height has also increased from just over three meters to eight meters, and the span on both sides has also increased to about fifteen meters. Such a big span. Coupled with the increased distance between the top and bottom, the space immediately becomes much wider. However, although the space here has become larger, it is not empty. Instead, you can see many artificially constructed fake coral reefs and various simulated landscapes. Anyway, they simulate the appearance of the natural landscape. Of course, artificial traces can still be seen at a glance in some places. After all, the gap with the natural environment is still obvious.

Although we didn't see anything after entering here, we immediately sensed the "huge danger" that was constantly releasing electrical pulses.

In fact, before we entered here, many ladies in the audience on both sides had already started to cover their mouths and exclaimed, because what was used as a checkpoint in the wide area here was not an artificial mechanism, but six great white sharks. .

There are many types of sharks. Among them, the great white shark is not the most ferocious or the largest, but it is definitely the first in overall strength. Those larger than it are not as fierce as it, and those larger than it are not as fierce as it. Anyway, the great white shark is definitely No. 1 in the shark family in terms of combat power. Of course, what's more important is that this is one of the few sharks that will actively attack humans. Although there are many types of sharks on the earth, there are only a few that can actually eat people. Most sharks are actually being eaten by people, rather than eating people.

Of course, great white sharks are often eaten by humans, but that is when humans use prepared harpoons and large nets to catch them. If both people and sharks are in the water, then in most cases it is the great white sharks that eat people, not people eating sharks, because even if you are equipped with an underwater harpoon gun, the success rate when facing great white sharks is not high.

The four of us now only have one sword in hand and no other weapons, as the other weapons were damaged in previous levels. The equipment the other party prepared for us was all rubbish, almost completely useless. The reason why there was only one sword left was because we carefully protected it, and because we attached so much importance to this sword, it was not because we hoped to use it to chop in the future. What to chop, but I think this thing is relatively long, and maybe it can be used as a stick in some parts of the mechanism. After all, we don’t know what the mechanism ahead is like. There is a tool that at least has a wider range of options.

These six great white sharks were obviously specially selected, because normal great white sharks are generally only between four and five meters in length, but the six great white sharks here are actually more than six meters long. Based on the normal size of a great white shark, a great white shark of this size is basically equivalent to a basketball center among great white sharks. Anyway, it is the kind of super long body, because most great white sharks do not actually grow that big.

Although these six great white sharks are all over six meters long. However, four of them are only about 6.23 meters long, and one is about 6.5 meters long, but the last one is more scary, looking at least seven meters long.

If this group of big guys were in the sea, even if more than a hundred people fell into the water, there would probably be no survivors, and now there are only four of us. We still faced six great white sharks.

Some people in the audience outside were worried, and some thought it should be fine. As for thinking this way, it was entirely due to the situation of the tigers before. However, after these people discussed with each other, most of them began to worry, because many people reacted suddenly. The difference between great white sharks and tigers is still very big. The tiger is an advanced predator. Its brain is actually not very low-level. Although it is incomparable to humans, the tiger's intelligence is still quite reliable. On the contrary, compared with the tiger who is both brave and smart. Jaws is a complete idiot.

I heard before that oceanographers would find all kinds of strange things in the stomachs of these big guys when they dissected sharks, and they even found solid cannonballs fired by ancient battleships. If sharks, like chickens, need to eat some stones to help digestion. It's not a big problem if it swallows some obviously inedible things, but the problem is that sharks don't actually need these things to help digestion. On the contrary, these things can cause indigestion in sharks. In this case, the shark will still swallow all kinds of edible and inedible things into its stomach. From this, you can imagine the shark's intelligence level.

This guy's intelligence level is completely different from that of Tiger. The prerequisite for humans to domesticate animals is that the creatures are smart enough, because if they are stupid to a certain extent, they will not be able to form sufficient conditioned reflexes, and therefore will not be able to recognize the concept of "master", and there will be no way to combine "please the master" with "please the master". Get rewarded” form an association because they do not have this ability to think associatively.

Sharks are one of the typical creatures that do not have this kind of thinking ability. Therefore, you have seen killer whale performances in aquariums, but you will never see anyone who dares to perform with great white sharks in an aquarium. Unless what he was trying to do was perform a suicide show.

Just because the audience suddenly analyzed that things like great white sharks cannot be tamed, and then deduced that we may not be able to comfort and control sharks, many people began to worry.

Compared with the past, where the audience did not take us seriously, and showed all kinds of contempt, contempt and even hatred, now many people's attitude towards us has changed very significantly, and some people's attitudes have even changed a hundred times. An eighty-degree U-turn. This phenomenon is actually a human instinct.

Because humans are social animals, they need a strong leader. Although subjectively these people know that we are not human beings, because of our appearance, they subconsciously apply us into the human system. Therefore, after discovering that we are very powerful, some people begin to instinctively want to get close to us. . This is actually an instinctive reaction to chase the strong and worship the strong, but many people don't know it.

Amid the attention of the audience with mixed expressions, the great white sharks discovered our presence almost immediately. It's not that we smell of blood, but because of the electromagnetic waves on our bodies.

Many people may not know that in addition to being the animals with the best sense of smell on the planet, sharks are also one of the few creatures with the ability to sense electromagnetic waves, and unlike many creatures, they are only within the range of sensing electromagnetic waves. Likewise, sharks really use this ability as radar.

Generally speaking, this is how great white sharks hunt. First, rely on the sense of smell that is more sensitive than an electronic sniffer to search for the smell of blood in the seawater, and then determine whether there is a target nearby. If so, then approach the area with a stronger smell, and then, in the second step, rely on its electromagnetic induction ability to determine the electric field of surrounding organisms, and draw the surrounding biological electric field distribution map in the brain to determine the target location. Of course, if the shark cannot smell blood, it may also directly use electromagnetic induction to determine the distribution of surrounding creatures, and then select a target to attack.

During this hunting process, electromagnetic induction is like a radar that helps the great white shark determine the types and distribution of surrounding creatures. Then it will instinctively select the electric field information of the main food type, and then track and attack. This process is a bit like the working principle of active radar-guided missiles, and the accuracy is very high.

Of course, the power plant sensor in Jaws is not entirely used as a radar. In addition to being used for range searches, great white sharks can also use electromagnetic induction capabilities to determine the Earth's magnetic field, thereby playing a role in global positioning. Of course, this is only a rough positioning, and it won't be that precise. Besides, sharks don't need such precise guidance capabilities. After all, they are not torpedoes.

In addition to locating and searching for targets, the great white shark's electromagnetic induction has a third application, which is to sense the emotions of creatures.

Yes, great white sharks have the ability to read minds. Although it can't see what you are thinking, it can know your mood. Fear is one of the electromagnetic wave characteristics that great white sharks like the most. When it finds a target emitting this type of signal, it will use it as its first attack sequence. Having this ability has many benefits for the great white shark. For example, it can rely on this ability to determine whether the target will resist. If conditions permit, it is obviously better to choose a fearful target who will not resist than to attack a brave target. A safer choice.

Although sharks don't mind fighting, this sensing ability can avoid unprovoked fights. After all, there are no hospitals in nature for you to treat and recuperate. Most injured wild animals have no hope of recovery. After all, the survival of animals The pressure is much greater than that of humans, and death is a very common thing for them. Therefore, even predators such as great white sharks or tigers, which have almost no rivals except humans, generally do not let themselves take risks easily, because their instincts tell them that they may die if they are injured.

These great white sharks relied on their electromagnetic induction ability to quickly draw a rough outline of us in their minds, but they could not sense our emotions because we dragons have electromagnetic control capabilities, so our brain waves are blocked. , it won’t spread if we don’t let it go.

Although they don't know our emotions, these great white sharks don't have any doubts. Their intelligence is not high enough to understand the emotion of doubts. After just a little sensing and no emotional signals, the great white sharks began to approach us in a roundabout way. Obviously, these guys were ready to attack, because there were no other creatures here except us. As for the spectators outside, because they are not in the water, the electric field will not be reflected in the brains of the great white sharks, so for them, the people outside are actually invisible.

Only four of our targets were found. The great white sharks, which had been starved for some time in advance, immediately made the decision to attack. Their desire to eat made them fearless.

"Look, those sharks are surrounding us." The surrounding crowd soon discovered the great white shark's intentions, and because of the large area of ​​​​the water area, some people began to run, hoping to get closer to the glass to see better. Be clearer. However, the great white sharks will not act according to the script. They have no intention of stopping at all. After approaching us, they only circled around us twice and then suddenly started hunting. (To be continued ~^~)
