An hour later, Shetland Islands, the place with the northernmost Pantolacken. The ship docked quietly in the falling snow. The group quietly jumped off the boat, and followed by another pair of knights, they arrived at the northern coast of the archipelago.

Make full use of the environment, from the natural black basalt reef from the outpost and the island and perfect integration. If the Viking's fleet approached from ten miles away, the sentries would be able to detect it in time and send their fleet to support them. Even if the Viking's fleet was huge and the outpost could not be dealt with, the Knights inside could still use the powerful Shield s to stand guard here for a few weeks.

This was the first time Arthur came to this kind of outpost. He pretended not to care, but his eyes scanned the interior structure of the outpost. Although it was made from a reef, the outpost was not as humid as Arthur had imagined. There seemed to be some sort of magic to prevent moisture from seeping into the insides of the outpost. In fact, if you could ignore the disgusting, rough, cratered rock walls, this outpost could be a very comfortable place to stay.

They walked about twenty feet down the stairs of the outpost, almost under the sea, before they reached the Mechanical Warehouse. The warehouse was connected to the bottom of the sea. Dozens of small scout submarines were anchored there. It could be said that they were the only armed force of the outpost.

The small submarine was about fifteen feet long and seemed capable of accommodating three passengers. Its jet black hull, which had almost no metal luster, was painted in such a way that it was extremely difficult to be discovered by enemies deep in the sea. Its streamlined design was elegant and simple. The entire submersible vehicle had almost no metal joints and was imprinted with a mold. Because of this, it was able to evenly distribute the water pressure throughout the hull, allowing a submarine of this size to have a strong ability to withstand pressure.

"Amazing, you humans have even developed this kind of machine?" "Bedivere looked at the submersible vehicle's precision and could not help but cry out in alarm.

Black Armoured Knight Zack chuckled. "

Strictly speaking, this is not something that modern people have come up with. We are merely replicating the machine according to the knowledge left behind by the ancients. The submersible vehicle was one of the many useful knowledge left behind by the ancient people.

Without the knowledge left behind by the ancient people, humans would have to wait another two to three thousand years before they could create such a powerful tool. If it had been zero learning, in the fifth century A.D., not even the great ships carrying people on ocean voyages would have been able to do it — we lacked the photonic engines that provided power.

Without the scientific knowledge left behind by the ancients, modern people would even have believed that the earth was a square piece of land — until 1589 BC, when archaeologists excavated the scientific books of the ancients and realized how stupid they were to assume that the earth was a square.

Ancient Kelton, Ancient Egypt, Ancient Rome, Ancient Greece, Cuba's Bilen … Although these ancient civilizations were destroyed, they spared no effort to preserve the most precious and valuable intellectual wealth for the modern era, allowing the humans in the Glorious Region to prosper.

How could these ancient civilizations, who fought each other and regarded each other as mortal enemies, work together to preserve these properties for modern man? This matter is still a mystery to this day.

The only thing that modern people knew was that these ancient civilizations once faced a very terrifying opponent, a race that the ancient texts called [Boundless Darkness]. Despair ancient people united to temporarily seal [the darkness] and to leave their best cultural heritage to future generations.

— — They put their hopes on the next generation.

"

"Well, let's cut to the chase. From here on, submarines will be used for undersea surveillance." His voice echoed in the empty warehouse. "Everyone be careful, your movements in the ocean will be restricted, and attacks against you will be very disadvantageous." "

"Can't we use a large submarine?" "Arthur looked at those small submarines that were restricted to three people and felt a little uneasy. These submarines looked like they would be broken pieces if they were touched, although it was just Arthur's reaction.

Captain Zack laughed. "Use heavy armaments at the border? Idiot, do you want to start an all-out war with Merman Race? — Even Merfolk Pisces could only incite the Viking to make all kinds of pirate raids on us. They didn't dare to openly invade!? "

"Why do things in such a roundabout way?" The Werewolf Boy Bedivere asked in puzzlement as he touched the black, slippery hull of the submersible vehicle out of curiosity.

"Because the one who waged the war always wanted to insist that he was [righteous]." The invaders always tried to put on a decent face so that they wouldn't look so ugly in the eyes of the world. Zack grinned coldly. "You're still young, you probably don't understand the rivalry between countries." But one day you will understand. The world of adults was just that fake and ugly. "

"I'd rather never be ugly." Werewolf Boy shook his head and looked at the captain.

"Haha, you can't refuse to grow up, kid." Zack said, "But you can try to maintain your kindness. -- Well, that's a good thing, so try your best. "

Bedivere could not help but look at Arthur. He noticed that the indifference on Knight Arthur's face had become even more severe.

Without any suspense, Arthur, Kai and Bedivere rode the same submarine. The submarine had obviously sunk a few inches into the water when Kay had jumped into it.

"Are you sure this stuff won't leak?" Arthur was a little nervous. He looked at the walls of the submersible vehicle and checked his surroundings again and again.

"Don't tell me …" Arthur, you haven't learned how to swim in all these years!? Kaye tapped the submarine with her hand and gave a cold laugh.

"No?" "I am a swordsman, not a swimmer!" "

"You--well, even if the submarine were to sink, I'd drag you ashore with me." Don't worry, I definitely won't drown. Sir Kay said helplessly.

"Then," Bedivere was so ashamed that his face was red, as he hid behind Knight Arthur: "Please, there's still a landlubber here. "

"Even you?!" Kaye sighed helplessly. "All right, all right!" The two little fellows aren't much of a burden, I can still handle them. I finally understand why I'm in your team, my life buoy! "

"I'm sorry, that's right." The captain's voice came through the communicator. "You guys hurry up and save the life--oh no, hurry up and get going." "

"Arthur's group began to dive deeper. Arthur said helplessly. He pressed the button to activate the submersible vehicle.

The submersible vehicle slowly dived into the water until it completely submerged. The submersible vehicle's cabin was shrouded in silence. Arthur took a deep breath in the darkness. The only light in front of him was the faint light emitted by the dashboard lights.

The silent underwater reconnaissance began.
