Two days later, Sun Feng took advantage of his free time to take a trip to the Pacific Ocean to have a look and choose a suitable island as a base for the establishment of the Invincible Pirates in the future! The Pacific Ocean is the ocean with the largest number of islands on the earth, with more than 20,000 large and small islands, covering an area of 4.4 million square kilometers, accounting for about 45% of the world's total island area. The Malay Archipelago, which lies between the Pacific Ocean and the Indian Ocean, is more than 4,500 kilometers long from east to west, and they divide the waters of the western Pacific Ocean into nearly 20 marginal seas and dozens of straits and waterways.

If you want to choose a location, it must be an isolated island, it is easier to defend, and it doesn't need to be very big, anyway, Sun Feng doesn't plan to need much, just use the weapon ox fork. Nothing else matters, the other is to be close to the main sea lanes, so that it can be conducive to robbery.

Just as Sun Feng was picking out the islands one by one, suddenly the voice assistant prompted Sun Feng: "Host, I found a very deep underwater cave!" ”

"Underwater caves, what's so strange, there are more underseas." Sun Feng was puzzled. He usually doesn't let the voice assistant prompt for something like this, and if he even prompts these, he will be dizzy to listen to these prompts.

"Host, this underwater cavern is very deep, like a straight mineshaft, leading to the center of the earth. Based on the probe search, I couldn't detect how deep it was, and the cave seemed a little weird. The voice assistant said.

"Weird?" Sun Feng frowned slightly, Sun Feng has not encountered such a thing, he encountered it twice last time, once where the alien aircraft sank, and the other was on the Bermuda Triangle.

"Could it be that there are alien aircraft or something like that?" Sun Feng guessed a little curiously.

"Host. Why don't we go and have a look, the entrance is a hundred kilometers ahead. The voice assistant said.

"Okay, let's go over and have a look." Sun Feng was not in a hurry to find the island. Anyway, it's impossible to form pirates as soon as this thing is found, and you have to recruit people, so you can't replace them all with robot bodyguards, right?

A hundred kilometers is not very far for a diving Warframe, it is quickly reached.

10,000 meters below the sea, in the midst of a strange rock at the bottom of the sea, a circular wellhead with a diameter of about 10 meters appeared in front of Sun Feng. The bottom of the sea under the 10,000-meter sea water is pitch black, and there are no points of light. There are no creatures or plants, and the atmosphere is a little scary.

"That's it?" Sun Feng asked, pointing to the well-like underground cave in front of him.

"Yes, the current detection and search function can only detect 3,000 meters underground. Not anymore. "You know, the detection and search function can detect a radius of 350 kilometers, which means that it can detect 150 kilometers even underground. Now it can only reach 3,000 meters, which is indeed weird.

"Let's go. Go down and take a look. Sun Feng didn't hesitate anything. Maybe it's a big treasure, but in Sun Feng's eyes, no one on the earth should be able to hurt himself and the diving armor at the moment. So I don't have to worry, although I feel a little scary when I look at the darkness all around, but Sun Feng doesn't feel this way, but is a little excited.

"Let's go!" In the next second, Sun Feng drove the diving armor and jumped into this bottomless well. After going there, Sun Feng noticed. The wells are round on all sides and are very flat, as if they were artificially formed, as if they were formed naturally.

Seeing this, Sun Feng didn't dare to relax in his heart, driving the diving armor, the searchlight and the detection and search functions were all turned on, and even the isolation shield was turned on, just in case.

This diameter is 10 meters, so it is very smooth to go down, don't be careful, and what makes Sun Feng a little surprised is that the diameter of this deep hole under the sea has always been like this, Sun Feng has gone down a thousand meters at this time, according to the data detected by the diving armor, the diameter of the cave is still 10 meters!

"It seems that this cave doesn't seem to be naturally formed, maybe it is artificially created, but it is artificial, who can do such a thing below 10,000 meters of sea water?" Ten thousand meters below the sea, don't say anything, even the pressure of the sea will crush you.

"Host, that's why I said it's weird here, and our detection and search function is also hindered by some kind of force, and we can't detect deeper places." Voice assistant said.

"Well, but I'm quite curious, what is under the bottom of the cave, is there a deep sea monster down there? Or is the cave leading to the underworld, or is there some race living underneath that we don't know about? Sun Feng said with a big brain.

"Host, you're thinking too much, if there were deep-sea monsters, they would have dominated the ocean a long time ago." The voice assistant pouted.

"Okay." Sun Feng felt that he had no common language with the voice assistant.

"Oh no, host, we're in trouble, the range of our probe search function is constantly being compressed by inexplicable forces, and the further we go, the smaller the range of our probe becomes. Now it's a radius of 2,000 meters! The voice assistant suddenly alarmed.

"Well, I know, it's all here, I must find out, I want to see what is down there! Let's be careful. Sun Feng knew that he was protected by an isolation shield, and the weapon system of the diving armor was also turned on, so he could fight at any time.

"It's 5,000 meters underground! Add in the 10,000-meter-deep water, and we're now below -15,000 meters. The hole is 5,000 meters deep, but it is not at the end of the tunnel. The voice assistant said.

"Hey, look at the cave walls! There are patterns and words! Sun Feng suddenly shone a searchlight on the cave wall and saw some dark red patterns and words.

"Stop, let's look into it!" This discovery shocked Sun Feng, this is indeed a bottomless underwater cave artificially created. The dark red patterns and words on the cave walls are a good proof of this, and they must have been artificially carved!

While seeing these patterns and words, Sun Feng also deeply felt an inexplicable pressure and panic, who could do such a thing under more than 10,000 meters of water pressure? Isn't it human? Looking at the age of these murals, it is very long, I don't know how many thousands of years.

"Could it be that there really is a race unknown to us humans in the bottom of the sea?" Sun Feng muttered to himself, because when he looked closer, Sun Feng couldn't understand any of these patterns and words, and they were not ancient human characters, not hieroglyphs, or other characters. Those patterns are all abstract things, and I can't read them at all! It's not animals, it's not plants, it's not humans, it's very abstract anyway, it's just some misshapen images, or some lines and so on.

"What the hell!" Sun Feng was a little crazy. However, he still let the diving armor take a picture and study it later. After Sun Feng took a round of shooting, he found that the one below was the same, so he didn't plan to shoot anymore and continued to dive down. At this time, the sea pressure has exploded, and you can imagine that it is now more than 10,000 meters below the sea.

But the shallow water armor is nothing short of these pressures.

Sun Feng drove the diving armor down slowly, he didn't dare to go down too fast, in case something special happened, he could still take precautions, he faintly felt that this time maybe something would happen.

Half an hour passed, Sun Feng looked at the light screen in front of him and saw that the data showed that it was now 10,000 meters underground! With the addition of 10,000 meters of seawater, it is 20,000 meters deep under the sea!

"OMG, why not to the end! If you continue like this, you will enter the center of the earth! Sun Feng saw that the soles of his feet were still pitch black, bottomless, like a bottomless pit, and the walls of the cave around were bright red murals and words, red, as if he was in a red enchantment, it looked quite terrifying. That's right, the previous dark red mural has become the bright red now, Sun Feng also stopped to observe, and found that these bright red things don't know what they are, for Mao for so long, under the immersion of sea water, it is still so bright red!

"Now the detection and search function of the diving armor has been 1,000 meters away from Yasuo!" The voice assistant reported.

"Yes, got it, keep diving." Sun Feng took a deep breath and continued to dive with the diving armor, although now there was a trace of fear in his heart, it was a fear of the unknown, but he had no intention of retreating! If you don't talk about it, you won't be able to sleep in the future!

"It is certainly not a human being to build this deep hole like a bottomless pit, because humans simply cannot do such a thing. I guess one is an alien, and the other is an undersea race or an underground race that can't exist. Sun Feng said.

"Yes, that's right, but you can't know until you get down there."

Another half an hour passed, and at this time, Sun Feng looked at the light screen, which was already 30,000 meters underground! That is, the bottom of the sea is 40,000 meters deep!

Sun Feng's head was already sweating slightly at this time, which was a manifestation of concentration and nervousness, "Now we are already in a cave 30,000 meters deep, and we don't know how deep it is below!" The further down, the more dignified Sun Feng became.

"Host, shall we continue, or go back?" The voice assistant also has no confidence at this time, although it doesn't take anything seriously, it is based on the fact that it has intermediate energy and high-level energy to be lawless. Now only primary energy is used, and the combat effectiveness is greatly reduced. Who knows if there's anything stronger down there than a diving armor? If it exists, it will be a big loss.

"Down, why don't you go down, it's a big deal it's a life-and-death struggle, I don't believe Lao Tzu will be so unlucky!" Sun Feng said loudly, although he didn't know the bottom of his heart, but he didn't plan to go back. (To be continued.) )
