After walking a little further, Jia Xu came to report: "Boss, the underwater sonar and other detectors have detected a huge elliptical cavity structure. It should be a sign of man-made construction. Should we send someone to take a look?"
Yu Qian'an: "I'll go over and take a look myself. Buu and Zilong come with me."
Buu stood up and walked out of the train with Yu Qian'an. The three of them jumped into the water with the water-repellent beads and sank quickly. This underwater cavity was more than two thousand meters away from the water surface. Yu Qian'an was a little confused. Where did so much water come from?
Just like if all the ice on the earth melted, the sea level would rise by about 66 meters. If there were really so many glaciers in this world, and their melting submerged the civilization of this world, causing the sea level to rise by two or three thousand meters, then the original size of the ice in this world would be unimaginable.
Arriving at the so-called cavity, the situation here once again overturned Yu Qi'an's cognition. Originally, Yu Qi'an thought that sea creatures should live in the sea water, just like SpongeBob SquarePants and Patrick Star, who built their homes in the water.
But Yu Qian'an saw an underwater city here, and it was the kind of city covered by a dome with a steel skeleton. The so-called cavity was the air bubble of that city, and the sea creatures lived in the air bubble.
Of course, outside the steel dome, there are some sea people’s houses distributed in a disorderly manner. It feels like the houses outside should be the slums of the sea people.
Zhao Yun was puzzled. "Boss, they clearly live in water where they can breathe more easily, feel more comfortable, and have greater combat effectiveness. Why would they choose to build a city like this on the seabed?"
Yu Qian'an smiled and said, "This should be to imitate the appearance of humans in the past. Although the sea people don't want to admit it, they were created by humans and are deeply influenced by humans.
When society develops to a certain stage, imitating humans should be what they think is the most effective way of governance.
Another issue is that seawater is corrosive. When society reaches a certain stage of development, luxury goods like clothing and gourmet food become the norm. Look at the clothes and bags women wear on the street—they're not suitable for use in seawater. And cooking, for that matter, is inherently unsuitable for use in water."
Yu Qian'an and the other two landed in the slums in stealth, and then Yu Qian'an used instant teleportation to enter the sea tribe's city. Entering here, it felt like entering a human city. Except that the people here looked different from humans, everything else was almost a one-to-one replica.
Yu Qian'an's purpose of coming here was not to visit, but to find the answer to why he had to stay here for a year.
However, Yu Qian'an felt that Jia Xu and his men were better at this kind of thing, so he used teleportation to bring Jia Xu over as well: "Wenhe, the task of gathering intelligence is now on you! I'll let Zilong follow you and protect you!"
Jia Xu: "Boss, Zilong should stay with you. I still have some ability to protect myself."
Yu Qian'an smiled and said, "You have the ability to protect yourself, and so do I. Then Zilong should act alone. Try your luck and you might get something different."
Zhao Yun cupped his hands: "Okay, boss!"
After the four of them separated, Yu Qian'an took Buu for a stroll on the street. When they passed a snack street, Buu couldn't walk anymore: "Hmph, I want to eat something delicious!"
Yu Qian'an: "I almost forgot you're a foodie. Then we need to become like them. I'm going to cast a spell on you. You can't use energy to destroy it, okay?"
Buu nodded happily, looking like a good baby. Yu Qian'an used magic to create an illusion that could deal with ordinary people. Then he got some money from someone, and the two of them showed up and started strolling around the snack street.
Half of the shops in the entire snack street sell snacks made from fish and marine plants. After trying them, Yu Qian'an felt that some of them tasted really good, but most of them were not suitable for Yu Qian'an's taste.
Buu, on the other hand, accepted everything and wanted to try everything.
Before they reached the end of the street, Buu had eaten up all the money Yu Qian'an had gotten. Yu Qian'an then got some more snacks from a shop and the two of them continued shopping. They finally finished the shopping within an hour and took Buu to eat all the snacks in the street.
Yu Qian'an shook his head helplessly. He had never been so patient with girls. This Buu seemed stupid. It was okay to drag him out to fight, but taking him on a reconnaissance mission like this would be a pure burden.
Buu was satisfied with the meal, and Yu Qian'an used teleportation to bring him back to the train: "Wait here for me, don't run around."
Buu nodded and stretched, then went straight to sleep after eating.
Yu Qian'an shook his head and continued his exploration. The entire city seemed to be running normally. There was no chaos caused by Yu Qian'an's train overhead. It seemed that at least for now, all trains were at peace with the sea people, otherwise the sea people's city would not be so peaceful.
Of course, the sea creatures are not pushovers. Apart from other things, the distance of two thousand meters under the sea is an unreachable depth for many trains.
Moreover, in the city that Yu Qian'an saw alone, there were at least hundreds of golden and more than a dozen three-color mythical sea creatures living there, and there were tens of thousands of red sea creatures below the gold level, among which the 3,000 sea army were all of the red level.
If the ghosts and monsters in the previous survival game were just guerrillas, fighting in the same way as in the martial arts world, then the sea tribe that we are about to face now is the real regular army under civilization.
Such battles are often very tricky. Military team battles can often exert combat power beyond their level, and it is also the enemy's home field. Yu Qian'an feels that the 3,000 sea tribe troops can at least challenge a three-color mythical hero.
It is still unknown how many such cities the sea people have. This is just a city defense army. If it is the high-level army of the imperial city, it should be at least gold level, and even three-color mythical level soldiers are not surprising. After all, the strength of the monsters faced in each world is increasing.
Yu Qian'an could already foresee that sometimes, wars were inevitable. Even if Yu Qian'an did not take action, other train captains might be tempted by the wealth of the sea people.
In Yu Qian'an's view, each train is an individual, but in the eyes of the sea people, these trains of unknown origin are a whole.
If one person makes enemies with the sea people, then the sea people will definitely hold the hatred against all the people on the train, and then all of them will be attacked.
Jia Xu contacted Yu Qian'an, who flashed over to Jia Xu's side. Jia Xu pointed to a book and said, "Boss, we've found the reason why it took a year. The location of this airport is right here!"
