After Ling Feng finished calling all his good brothers and friends, he was about to enter the Infinite Arsenal to exchange weapons and equipment.

Especially the submarine that is the most critical to escape, this must be exchanged in advance, and the only thing that worries him is that he doesn't know if his remaining 500,000 honor achievement points can be exchanged for the submarine he wants.

He quickly closed the room, then reversed, then drank another potion, and after doing all this, he sat on the edge of the bed, slowly closed his eyes, and touched the mysterious light hidden in the depths of his mind.

Suddenly, a familiar and cold mechanical voice suddenly sounded in his head. "Do you want to enter the Infinity Arsenal immediately?"

"Yes, I'm going to enter the Infinite Arsenal at once!"

When Ling Feng just responded in his mind, in an instant, his figure disappeared out of thin air.

Airplanes! ……

After a brief but familiar void in his brain, he opened his eyes again, and Ling Feng found himself in the Infinite Arsenal.

At this time, the familiar voice of the robot Taishan sounded in his ears again. "Welcome to the Infinity Arsenal again, is there anything I need to do for you?"

Hearing this, Ling Feng turned his head to look at Taishan, and said with a smile: "Taishan hasn't seen you for a long time, I came in this time to exchange some arms and equipment with the system." ”

Tarzan nodded, "Okay, sir, please move to the giant display and follow the system's prompts." ”

At that moment, Ling Feng quickly came to the side of the giant display screen and looked at the blank screen on the giant display screen. He quickly commanded, "I'm going to enter the exchange shop!" ”

As soon as these words came out, all of a sudden, the picture on the giant display suddenly changed, and then an arms exchange shop appeared in the giant display screen.

At this time, the computer voice in the display screen reminded: "Sir, please choose the type of arms and equipment to be exchanged!" ”

Ling Feng commanded without thinking: "Submarine! I want to exchange for subs! ”

After hearing Ling Feng's order, the screen of the giant display screen flashed again, and then a submarine exchange area appeared.

After entering the submarine exchange area. Suddenly. A large number of submarine patterns appear on the display, and in these submarine patterns, submarines of various types and produced by various countries. It's got it all.

There are modern submarines. There are also some futuristic submarines with very strange shapes.

Look at the submarine pattern that spreads across the entire display. Ling Feng was dazzled and excited.

Because, he came from inside these submarine patterns. See many of the most advanced nuclear-powered submarines in the world today. For example, Russia's "merry-go-round" nuclear submarine and the world's most advanced ballistic missile nuclear submarine -- the US "Ohio"-class ballistic missile nuclear submarine, and he was pleasantly surprised to see that the most famous US nuclear submarine, the "Seawolf," is claimed to be the world's most advanced attack nuclear submarine.

However, these nuclear submarines are representatives of the most outstanding combat nuclear submarines in the world today, and at the same time, their exchange prices are also very expensive, like Russia's merry-go-round, its exchange price is 2 million achievement points, as for the United States' "Ohio" and "Seawolf" nuclear-powered submarines, their prices are more than 1.5 million.

However, none of these modern nuclear submarines have the highest exchange price, because Ling Feng found several attack submarines among those attack submarines produced in the future, and their exchange prices are called against the sky, which are basically more than five million.

Among them, there is a future attack submarine called "Deep Sea Shark", and its exchange price is as high as 10 million honor achievement points, and Ling Feng gasped when he saw it.

Seriously, Ling Feng really doesn't know much about these submarines, and if he wants to exchange them now, he doesn't know that it's better to exchange them, because the price is too expensive, and he can't afford to exchange them, even if he exchanges them now, it is estimated that a large number of intelligent robots will be needed to fully make the submarine work.

There are many low-cost pocket submarines, but the exchange price is very cheap, and it doesn't play a role for him. Because, the pocket submarine carries a maximum of two or three people, and after they meet in Haimen County tomorrow, it is estimated that the total number of people is at least close to about twenty.

With so many people, at least they have to exchange for a small and medium-sized submarine in order to be completely hidden.

At the same time, the submarine he exchanged should not be too backward, if the submarine is too backward, then the submarine will make a lot of noise when it dives into deep water, so that it can be easily monitored by the federal government's naval fleet.

Thinking of this, Ling Feng couldn't make up his mind at all for a while, because he didn't know what kind of submarine to exchange for.

At this moment, Taishan, who was standing on the side, seemed to have guessed his thoughts, and asked respectfully, "Sir, is there anything you don't understand or need my help with?" ”

Hearing this, Ling Feng nodded again and again: "That...... That Tarzan, I want to exchange for a submarine, the price is not too expensive, as long as it can accommodate twenty people to escape. ”

Tarzan nodded, and then asked, "Other than that, sir, do you have any other requirements?" Like, the defense and attack forces of submarines? ”

Ling Feng lowered his head and thought for a while, and said, "I just want to exchange for a submarine for diving and escape, as for weapons and the like, I don't need it." My requirements, though, are simple, first; The submarine must be able to accommodate more than twenty people, second; The submarine must be able to evade enemy monitoring and detection, thirdly; It's better to exchange the price of the submarine at around 300,000, otherwise it's too expensive, and I can't afford it, because I don't have that many honor achievement points. ”

Hearing this, Taishan nodded and said, "Okay, sir, according to your three requirements just now, I think there is a submarine called "Explorer" deep-sea exploration and mining submarine, which is very much in line with your requirements just now. ”

"Explorer?"

Ling Feng asked the price question he was most concerned about: "What is the exchange price of this explorer?" ”

"This explorer is a medium-sized submarine, because its main role is not to fight. It is used for diving to the bottom of the sea for exploration work, so the submarine is not equipped with much weapons and equipment, so its exchange price is relatively cheap, as long as 300,000 honorary achievement points, it can be successfully exchanged. ”

Hearing this, Ling Feng nodded and said, "This expedition ship can accommodate twenty people, it shouldn't be much of a problem, right?" ”

Taishan said: "Sir, it's no problem at all. ”

He groaned for a moment. Ling Feng pondered slightly for a moment. "Okay, just follow the advice you gave me, and I'll exchange it for an explorer submarine." ”

After listening to Taishan's advice to himself, Ling Feng looked up at the display screen again. He commanded loudly: "I want to exchange for a submarine "Explorer"! ”

As soon as this statement came out. Suddenly. The computer voice in the display rang suddenly. "To exchange for an Explorer submarine, it takes 300,000 honor achievement points, are you sure to exchange it?"

Ling Feng replied without thinking, "Yes." I want to redeem it now! ”

The computer sound in the monitor sounded again. "Confirm that the exchange is successful, now please accept the arms and equipment, sir!"

Just as the sound of the system in the display screen fell, suddenly, in the giant display screen, there was a sudden flicker, and then, in the corner of the wide arsenal, a dazzling light suddenly burst out, and after a while, the light faded, at this time, a huge and pitch-black submarine appeared in front of Ling Feng's eyes.

When Ling Feng successfully exchanged the "Explorer" submarine, at this time, Taishan pointed to the submarine and began to introduce Ling Feng. "Sir, this Explorer submarine, this type of submarine adopts a single-hull single-compartment design, 36.2 meters long, a pressure-resistant hull diameter of 5.2 meters, a displacement of about 800 tons, a maximum diving depth of 750 meters, and a crew of about 12 people, but sir, you are not here to attack and fight, so there are more people, and the space in the submarine should be enough. The submarine is powered by a high-energy battery, so you will have to exchange some high-energy batteries for backup during the journey. In addition, the maximum speed of the submarine is 45 knots per hour when it is underwater and 32 knots per hour when it is on the surface......"

Ling Feng heard Taishan say a lot of professional terms in the process of introduction, and he fainted on the spot, and hurriedly waved his hand to stop: "Wait...... Tarzan, let me ask, what ...... What does that submarine sail at forty-five knots per hour, what does it mean? In this way, you can tell me in an easy-to-understand sense, how many kilometers per hour is the maximum speed of this submarine in the water, how long can it stay underwater at most, and the most important point, will we be discovered by the enemy if we hide in the submarine? ”

Hearing this, Taishan hesitated for a moment, nodded and said: "Sir, when this submarine is sneaking underwater, the maximum speed can be as high as eighty-two kilometers per hour, every four hundred and eighty hours, the submarine needs to surface for ventilation, as for the safety of this explorer, this chief does not have to worry at all, because its power system is using very advanced future technology, so in the process of deep-water diving, the sound it makes is very small, and the submarine is also equipped with very advanced stealth devices, With your modern technology, it's basically very difficult to spot it. ”

Listening to its detailed explanation, although Ling Feng didn't fully understand, he still felt that this "Explorer" submarine seemed to be very awesome.

However, although he has successfully exchanged the submarine for now, he still needs to figure out how many people need to control the submarine before it can be fully operational. Of course, Ling Feng's meaning was obvious, he wanted to know that this submarine needed at least a few robots to control the navigation, anyway, all other armed forces gave up, as long as it could be driven.

Because, Ling Feng is in the arsenal, there is only one seventh-generation robot and twelfth-generation robot, as for the seventh-generation robot, it must be a high-end robot, and it must be no problem for it to control the submarine, but the key is that those first-generation robots don't know if they can handle this task. If Tarzan tells him that a generation of robots is not up to the task of controlling submarines, then wouldn't he have to exchange for some higher-level robots?

Ling Feng's remaining honor and achievement value is now less than 200,000, and he really doesn't want such a thing to happen...... (To be continued......)
