By Bismarck's description, the AdmiralityCode is real. Pen & Fun & Pavilion www.biquge.info it's not a virtual instruction, but comes from somewhere.

However, Bismarck had not received instructions from AdmiralityCode again for a long time. It should be said that since the sea battle, AdmiralityCode has almost disappeared without a trace. Although AdmiralityCode did not issue any secret orders again. But Bismarck was able to find out where the AdmiralityCode was located through some clues.

To everyone's surprise, this location is actually in Antarctica! Antarctica, the coldest location in the world, is completely uninhabited. Especially now that the transportation of the ocean is cut off by sea fog, even the most basic Antarctic research station can no longer be maintained. The current Antarctic is almost a forbidden place for humans.

However, when he heard that his target might be in Antarctica, Yun Qi couldn't help but look at the map and sighed. He and others have just crossed nearly 3,000 kilometers to Europe, and now they have to cross the entire Atlantic Ocean and the Indian Ocean before they can reach Antarctica. It's a hard life!

According to Bismarck's information, the AdmiralityCode may be hidden in the land of Empress Maude. But AdmiralityCode isn't on the surface of Antarctica, it's in the mysterious Antarctic underworld.

Although Bismarck had already determined the location of the AdmiralityCode, it was not easy to find and travel to this underworld. After all, Antarctica is a huge land mass of more than 13.9 million square kilometers, and with a large amount of ice and snow cover, it is not easy to find a gateway to Antarctica's underground world.

However, Bismarck, after several explorations, had roughly determined that the location of the entrance should be in the sea where Empress Maude's land was located. This has saved Yunqi and them a lot of search time.

And Bismarck, a tsundere girl, took the initiative to ask for guidance in the name of worrying about her friend Iona. To paraphrase her, isn't it normal for friends to help each other when they are in trouble? According to the information she Bismarck has collected over the years, human beings often use the word "sticking a knife in the ribs" for a friend to indicate that as long as a friend is in trouble, he will definitely support him!

Hearing Bismarck's remarks, Yun Qi smiled faintly. This tsundere girl probably only listened to the first half. The second half is estimated to be wild history, but she didn't care. If Bismarck had known the second half, he would certainly not have thought so. The second half of this sentence is a classic reversal. The front is for the "brother two ribs knife". As a result, it was "two stabs for my wife and brother!"

However, there was a girl who took the initiative to ask for help, how could Yun Qi cruelly refuse! So Yun Qi silently did not say this paragraph, so as not to hit Bismarck's pure and young heart.

Soon, after Bismecca joined, the group set off for Antarctica in search of the legendary AdmiralityCode.

After five days of high-speed sailing, everyone finally entered the Antarctic region!

It is a virgin land that has not been explored by humans, and it is the last paradise on earth. The whole of Antarctica is covered in silver. Endless blizzards envelop Antarctica, making it a place with endless snowflakes all year round.

The entire continental shelf is covered with extremely thick ice. These ices melt almost all year round, and in some places even condensed 10,000 years ago. It would not be an exaggeration to say that they are 10,000-year-old ice.

The two sea fog warships, I-401 and Bismarck, had reached the waters of Empress Maud's land at this time. There are a lot of icebergs floating in the sea, and even sea fog warships have to be careful not to hit these huge icebergs. Because these icebergs, which do not look big on the surface, are actually just illusions. The entire iceberg is less than five percent of the iceberg's surface exposed. That's what the tip of the iceberg means. If you stumble into these Xiaoice tips, which are less than a few meters away, you will find that there are actually icebergs hidden beneath the surface of the sea. Even if the Sea Fog battleship had a Klein position, such a ramming would have been fatal. This will significantly slow down the speed of the battleship.

And to make matters worse, sometimes the entire sea is covered in ice. If you want to pass through here, you have to force the iceberg open. And this task was honorably given to Bismarck. Who wants her to be a big warship? To break the ice, you first have to weigh enough. Otherwise, it would be embarrassing to rush onto the ice, only to find that your weight could not collapse the thick ice at all. If you're not careful, you might run aground!

Bismarck, who was assigned to the ice-breaking task, looked like a "big husband" on the surface, indicating that there was something wrong with the wood. But my heart is dripping blood!

I saw my beautiful hull hanging on the thick ice, hanging and hanging! The original perfect paint was hung into a mess of modern art graffiti. This is really a disaster for the tsundere Bismarck. Unfortunately, she had to pretend that she didn't care, so that her new friend Iona wouldn't worry about her. To make a mere submarine worry about a large warship, Bismarck said that it was too faceless. So I won't say it if I kill it!

On the other side, Yun Qi and Iona are manipulating I-401 to find the location of the underground entrance to Antarctica at the bottom of the sea.

At this time, Hinata who had been idle next to him helped a lot. I-401 alone would not have been able to quickly find the hidden underground entrance. But with Hinata, it's different.

After consuming a large amount of nanomaterials, Hinata has built a number of specialized unmanned detectors. These small detectors are capable of extremely accurate detection at extremely high speeds at up to 500 kilometers within range of I-401. Although the accuracy of its detection is not as good as that of the detection device that comes with the Yi 401, it is not as large as the number!

Hinata is worthy of being a professional scholar-type mental model, and it only consumes the nanomaterials in the inventory of Yi 401. Hyuga has made as many as thirty special unmanned exploration vessels. These small exploration vessels, which are less than three meters in size, can travel for a full twenty hours at a high speed of 80 knots underwater.

When the energy is almost exhausted, these small ships will automatically return to the I-401 to replenish their energy. Relying on these almost pervasive small detection ships, the detection speed has been greatly accelerated. Just a day later, Hinata spotted a clue through these small unmanned exploration ships.

It was an extremely secluded cave. The reason why this cave was found to be abnormal was because an unmanned exploration ship accidentally passed by the cave and found that the temperature of the water flowing from the cave was less than 0.5 degrees higher than the temperature of the surrounding seawater. Such a small temperature difference, if not just skipping this hole. It is impossible to find out.
