It is worthy of being Lilu who has been baptized in the water element world for three years. She held Gao Sen and separated a space of two meters around their bodies, making Gao Sen not worry about clothes.

The Cancer Warriors who dived with him around took advantage of their already underwater breathing ability, so they naturally didn't have to be afraid of lack of oxygen.

Zeratu, who was on the side, didn't have to breathe at all. The people of the Protes were half-energy and half-enterprises, and they were simply races that could navigate the universe with naked bodies. They had no requirements for air at all. Of course, there was no resistance to water pressure.

After sailing in the sea for more than an hour, Gao Sen's photosensitive system finally felt the light source outside of biolight, and the range was very wide. Judging from the memories of the two small things, it should be the lighting of the underwater city.

Suddenly, a harsh sound came from the seas on all sides, and the tone was sometimes high and sometimes low, as if it was a sound made by some kind of marine creature.

Lilu, who was beside Gao Sen, left Gao Sen's arms, leaned her face close to the water, and then made a harsh sound, but the tone was obviously different from the one just now.

"The other party was asking who we were, why we suddenly approached their kingdom, and whether we had permission from anyone. They asked us to answer immediately." Lilu, who ended the seemingly out-of-distance dialogue, turned around and explained to Gao Sen.

"How did you answer?" Gao Sen asked.

"I told them. We did not receive any invitation from anyone. We were envoys from another kingdom. We visited all the way here, hoping to see their king. Now the other party has not responded, so we should be reporting the news. Because it should be coming soon." Lilu said.

"Now I can only pray to Lerento for everything going well." Gaosen made a standard and devoted Lerento etiquette.

"But what if they don't return it to us?" Lilu asked with some concern. Although most sea tribes are not cruel, they have no favoritism for humans, and they believe that the creatures walking on land are all inferior creatures. It is impossible to have any good fruits to eat.

"That's even better, just grab it." Gao Sen said indifferently.

"Anyway, I'm not a person who is afraid of water. Staying in the water for a day or two will have no effect on me."

When the other party appeared again, Gao Sen finally understood what kind of guy he was communicating with them in the strange sea language.

A shark covered with a current-shaped tattoo. There were several dolphins next to him.

It looks like a very strange combination.

"Our great kings do not want to see you, humans, but you are allowed to pass through our sky, and you can leave, provided that you do not cause trouble here." The shark said in a common word that Gao Sen could understand. Looking at the flow of the sea water around him and the discomfort of his pronunciation, you can tell how uncomfortable the other party is.

"No, I don't think you understand. I hope to meet your king, not to pass by here." Gao Sen replied politely.

"What I didn't understand is you, humans, our great sea tribe does not need to care about anything with humans. We don't need to get anything from you, and you don't want to get anything from us. Please leave." The shark said in a bad tone, and issued a very firm way to chase the guests. At the same time, he looked at the huge Cancer warriors around him with a very worried look, although they had no movement at all, just floating quietly.

Unfortunately, Gao Sen came to find trouble and could not listen to him at all.

"I hope you can inform you again that I am here to retrieve what I have placed on the Island of End. The king should understand what's going on." Gao Sen said.

"I said that our king will not see you." The shark exposed the two rows of razor-like teeth in his mouth and said word by word to Gao Sen.

"I'm sorry then." Gao Sen raised his hand, and several light green fluorescent lights broke through the water barrier and shot through several big fish in the water.

The resistance in the water restricted their movements. Although they made some dodging actions, they were still shot by those green lights, but nothing happened.

"Human! Are you provoking at this time?!" The shark was very angry and roared at Gao Sen with a big mouth. There were also some sea tribe language mixed in it.

"Of course not. This thing is a crystallized anesthetic, non-toxic and has no side effects. The best advantage is that it works quickly and is green and environmentally friendly. It often doesn't wait for me to finish..."

The sharks and dolphins began to be even unclear, and the sharks began to sink, while the dolphins floated upwards.

"It will all fall down." Gao Sen finished his words.

After dealing with the first batch of enemies, Gao Sen naturally had to advance towards the distant city. The Cancer Warriors had been hiding under them just now. As long as the other party really launched heavy troops, the Cancer Warriors who were never afraid of fighting in the sea would naturally not lose to anyone.

When Gao Sen walked around a sea-understorm mountain range, what appeared before Gao Sen was a beautiful city. The city seemed to be built in a giant bubble. The huge cover isolated all the city buildings from the sea water outside. Various creatures flew back and forth around the city. Under the illumination of the yellow light, the whole city seemed like a fairy tale world. In addition to the surrounding sea, Gao Sen even felt that he was not in this world.

The other party’s city buildings are really weird.

All buildings are basically conch-shaped, long conch, flat conch, and various conchs are covered with blocks of all sizes. Gao Sen looked carefully and found that there was no drop of water in the entire city. Many sea tribes actually walked inside! It was so strange.

All the water is just surrounded by the outer periphery of the city. I really don’t know how this is the case to create a cover with such pressure resistance.

Between the conchs of all sizes, there are also houses made of corals... or castles. In terms of quantity, it is very rare, with less than a dozen. In the middle of the entire city, there is a giant building made of red coral, which is inlaid with dense beads that emit various lights. These pillars are made of strange patterns. Based on the geographical location of the building and its uniqueness, Gao Sen can basically determine that this is the palace.

This defensive cover can resist such powerful water pressure. It seems that it is not something that can be easily hit, so it is better to go through the gate.

Although it is just a small country that looks small, it seems to be quite lively. It seems that the entrance and exit passages of the city gate are full of people. Gao Sen found that in this sea where buoyancy resists gravity, the possibility of growing into a giant is very high. The Cancer samurai who is seven meters tall is nothing at all. Gao Sen even has two big guys over ten meters tall queuing forward. However, the arrival of Gao Sen and his gang still attracted the attention of many people. Many people in line forth curiously pointed at the samurai who were more than seven meters and covered in heavy shells.

"Those two guys are from the Blue Whale clan. They are a race with a bad temper. I have never seen people from their clan get angry before, and they are very slow to react. Basically, if you step on his feet, he will scream for a long time." Lilu lay down next to Gao Sen's ear and whispered. Lilu was very happy to be able to go to the sea with Gao Sen. Lilu, who is usually very quiet, has also become more talkative and constantly introduces some strange sea races to Gao Sen.

Perhaps because of the serious large-scale ethnicity in the sea, the gates entering the city are also set up to be super huge. From the appearance, it is a giant pipe with a diameter of twenty meters.

It was not until it was approaching that Gao Sen remembered something. So many people lined up to enter the sea. It was not because they could only enter if they were handsome or not. It must be money. But Gao Sen knew the rules of coins in the sea, and even Lilu didn't understand it. The rules of coins in various countries in the sea were not common.

"Where is the race, the purpose, from?" The guarding the gate were four shark warriors covered in silver armor. They were interrogating the two blue whale tribes in front of Gao Sen. Of course, these languages ​​were translated by Lilu.

Unlike the shark Gao Sen just saw, the shark warriors have human-like bodies, but overall they look like a shark, with small eyes, big mouth, razor teeth, and muscles all over their body. The steel fork in their hands is even more shining with cold light. It seems that they were made of mitril silver!

"Actually, in the sea, do you know what you lack the most?" Lilu said to Gao Sen in a low voice.

"Lack? Is it land?" Gao Sen couldn't help but think of an ancient movie called Future Water World. In that movie, the value of land is more expensive than human life.

"Land?" Lilu was happy. "What's the use of that thing we want? We can't eat it. Is there a lack of land in the sea? All our crops are planted in the sea, and there is no need for any land at all?" Lilu gently hammered Gao Sen's chest and denied this view.

"It's metal." Lilu did not ask Gao Sen to continue guessing, but directly revealed the answer.

"No ordinary metal can maintain its stable properties for a long time under the soaking of sea water, but it will be damaged for a long time. Although there are mineral veins in the sea, there is no smelting technology, so the metal inside cannot be extracted into any useful tool."

"Under the erosion of water elements, no metal product can be preserved for a long time except those real precious metals."

"So, in the sea, the most expensive thing is metals, especially those that have excellent corrosion resistance."
