The method of activating the "water repellent bead" is very simple, and there is no need for European gas, the bead has its own energy, and it can be pressed a few times with a special technique.

Transparent bubbles formed around him, enveloping Chen Mu inside, and the monkey rode on his shoulder, guided by Dorothy, diving all the way.

The coral reefs on the surface of the sea seem to act as only coordinates, and they go down here, deep into the pitch-black seafloor.

The bubbles have a little glimmer of their own, which is very eye-catching in the dark environment, but such a little light is not enough to illuminate the road ahead.

Chen Mu had night vision, but he didn't show it, pretending to be a normal human being, and honestly followed Dorothy.

Dorothy threw out a sea urchin-like object that seemed to be alive and actively lit up in front of the group, emitting a bright emerald green glow that lit up a large area around it, but it was not dazzling.

After diving for a distance, the surrounding sea gradually brightened, not because the sea itself glows, but because there are many such glowing sea urchins around.

These things are like street lamps on the bottom of the sea, moving around the area regularly, driving away the darkness around them.

"Alright, there's our camp ahead, please come with me. ”

Dorothy's voice was able to transmit through the water, and through Chen Mu's bubbles, so that he could hear it clearly.

Soon, Chen Mu saw the "camp" in front of him and was immediately shocked.

It's a small underwater city, and from a distance, it looks like the lost Atlantis of a fairy tale, or an underwater paradise from a cartoon.

Several oversized transparent shields, crystal clear upside down on the bottom of the sea, inside are pieces of buildings, all made of shells, corals and the like, which look beautiful.

Outside the city, there are many sea beasts roaming, some of which are also riding mermaid warriors, who should be the guards of the city.

Seeing Dorothy and them coming, no one came to interrogate, but Chen Mu keenly sensed that bursts of ultrasonic waves were transmitted in the water, which should be the communication method within the mermaid clan.

The seven-person team took Chen Mu to the top of the city, the shield on the far right, this seems to be a place similar to an airport, there are many mermaids and sea beasts coming in and out, and there are even some things that look like ships, but the shape is more strange.

Dorothy led Chen Mu through the gate, into the inside of the shield, which was still seawater, and then advanced a distance, turned into a dividing area on the right, and passed through a bubble wall, which was a waterless area.

"Okay, you can turn off the bubbles, the air structure here is similar to the outside, and humans can walk and move here just like outside. ”

Dorothy's mount hovered about half a meter above the ground, holding her up on it, and the other six people's mounts were not so bad, and had to stay outside in the sea.

Three of them followed behind Dorothy, and they were also in a state of floating, but they were floating in the air with their own strength, which showed that they were all innate level martial artists.

Think about it, the adult mermaid clan has innate level combat power, and the mermaid clan also takes the path of European qi and ancient martial arts, and the innate martial artist is also an entry level for them, which is not worth mentioning.

After Dorothy brought Chen Mu here, she explained a few more words, and then left, leaving no one else to look at Chen Mu, who seemed to be very relieved of him.

Chen Mu knew that the other party was not reassuring him, but this kind of undersea city was not something that he could leave single-handedly.

However, considering the current situation, the mermaid clan will not be difficult for a little person like themselves, at most they will stay for a period of time, and it is estimated that there will be follow-up mermaids to communicate with themselves, and there will be room for operation at that time.

According to Dorothy, this is the settlement of human beings in this underwater city, which is equivalent to the centralized management of the foreign population.

However, looking at the deserted appearance here, there are not a few figures in the huge place, which proves Chen Mu's previous guess more and more.

It seems that the situation at the "Doom Corner" is very bad, there are not many refugees who have fled from the north, and it is likely that most of the humans who remain here have not had time to return.

Dorothy also did not restrict Chen Mu's personal freedom, so in this area of human activity, he could move freely.

After communicating quietly with the monkey, Chen Mu decided to wander around first, and it was best to find a local to find out.

Of course, by locals, he meant the humans who made a living here, not the local merfolk.

It is said that the merfolk and the merfolk have one thing in common, that is, the internal cohesion and sense of identity are still very high, and it is almost never heard of such a cannibalistic and infighting as humans.

Therefore, if you ask for local information about the mermaid, you can only start with the humans who are temporarily living in the local area.

Before, from a distance, this undersea city was not very big, but after actually entering, Chen Mu found that the space inside was terrifyingly large.

It's not that the city is really large, but that there are caves inside, and when you look at it from above, you think it's a low-rise building made of shells and coral reefs.

But after coming in, I realized that it was a very three-dimensional structure, sometimes from the outside it looks like just a few ordinary shells stacked together, but when I walked in, I realized that the inside was in all directions, and it was even likely to be a small labyrinth building.

This is only an area of human activity, there is no seawater, if it is an area of mermaid activity, it is estimated that it is really a variety of underwater mazes.

Looking at the scale of this area, Chen Mu also had a guess in his heart, this so-called "camp" is likely to be one of the gateway strongholds of the mermaid clan in the northwest of the "Golden Sea", and it should still be a relatively important kind, otherwise there is no reason to build a temporary residence for humans of this scale.

According to the size of this place, not to mention receiving dozens or hundreds of refugees, even those large ocean-going trade fleets should be able to receive one or two here.

You must know that the fleet that can do ocean trade is at least a thousand people, and the large capital ships alone must exceed ten, and if you count all kinds of auxiliary ships, it is likely to exceed 100.

Only on such a scale can we barely be qualified for ocean trade, and we have to take a relatively mature shipping route, which is a relatively safe route, otherwise even if it encounters a natural disaster, or a certain terrifying-level sea monster, it is enough to wipe out the fleet.

The area that can receive thousands of people is naturally a one-stop shop for eating, drinking and having fun, and there should be any kind of venue, but Chen Mu wandered around and finally found a tavern that was still open, which shows how depressed the business has been recently.
