Yu Tu and the others quickly followed. With soul perception, it can ensure that they always bite behind each other, without worrying about the problem of losing, and will not be easily found.

When they returned near the original river, Bi Tianyi was already approaching. The bright fireball is still easy to notice.

Those monsters all went underwater, and Yu Tu and the two went directly into the water without hesitation.

Soon after they left, Bi Tianyi rushed to the river and turned into the sun again, driving the darkness out.

Its eyes penetrated the dark lake and saw Yu Mu's back.

"Boy, this is your only chance. Cherish it."

Yu Mu seemed to sense something underwater and turned around and took a look.

Yu Tu on the side looked at him and asked with gestures. Yu Mu shook his head, and the two moved on.

After traveling for a while, they encountered a narrow underwater passage.

Yu Tu frowned. This channel is not in perception. Of course, this may be a flaw in the perception of the soul. It is difficult for him to find those dark reefs underwater. It seems that the water current limits the ability to perceive.

In his perception, the monsters did not rush into this passage when they passed by, as if they were passing directly through the wall.

After that, Yu Tu laughed herself. Those guys are resentful spirits. It's normal to go through walls or something.

Just make sure that there are no enemies. Signaling Yu Mu to keep up, Yu Tu took the lead into the passage.

The passage is very long and narrow. After passing through the passage, they entered a bright underwater world.

A large number of night pearl-like stones illuminate this area. A large number of reefs were cut through, forming places for people to live. This reminded Yu Tu of the ruins of the earth element elves he encountered for the first time. This is also the technique of chiseling in the rock.

From the simple sculptures and portrayals, it can be seen that this is a mermaid village.

Of course, they can also see those mermaids who are performing some kind of ritual.

In a place like a square, thousands of merfolk held hands and sang strange songs. In the passage they vacated, a team of Saslow's wraith spirits reduced their resentful expressions on their faces, as if they had been purified.

Afterwards, these cleansed resentful spirits naturally walked into the void in the middle of the square and disappeared. Yu Tu observed carefully for a period of time, and determined that the hole was a portal for teleportation.

Possibly, the royal city is on the other side of the portal.

But the question now is how to approach the portal without disturbing these merfolk and wraith spirits.

Yu Tu and the two of them thought of many ways. Unfortunately, I can't see. The most reliable thing is to use the power of heraldry to disguise yourself and slowly approach the seabed.

But camouflage is almost useless underwater. It is impossible to hide the changes in the current from those mermaids. If you really want to get into the void, you can only break through.

They can only wait for the end of the ceremony and see the situation before deciding the next step.

At this time, they carefully looked at the mermaids.

These mermaids are not the legendary mermaids. They are indeed a combination of human body and fish tail. But the skin is light blue, and the human body has hard bone fragments, just like armor. Sharp teeth, thin cheeks. The weapon is stone. However, it is not difficult to judge the specific situation.

There are also some shaman-like existences in the mermaid school. Responsible for presiding over consciousness. Those shamans are full of magic. If Yu Tu didn't make a mistake, there would probably be six of the fifth ranks. But did not see the sixth order. It cannot be ruled out that the sixth order did not appear.

While they were waiting patiently, they suddenly saw a different mermaid rushing towards the team. He was quickly stopped by someone.

The smaller mermaid is fundamentally different from the other mermaid. beautiful. The upper body is no different from ordinary people, wearing clothes made of shell pearls. The face is very close to the human race. Only the gill fins and fangs are retained. The hair is a bright red, very bright.

And her fish tail is pure white, with red scales interspersed in the middle, like hidden red lines.

"This style is like Hongguang Naga."

"Indeed. It seems that the status of that mermaid is very high."

The following dispute continued, and in the end, the mermaid was helplessly taken away by two guards. Eight female mermaids followed.

Yu Tu and Yu Mu looked at each other, nodded, and immediately followed silently.

After passing through the square, the painting style of the whole world suddenly changed.

The original building made of reef disappeared and replaced by an underwater city like the crystal palace in the myth.

The mermaid here looks the same as the smaller mermaid, with the upper body and approaching people, but it also retains the mermaid's hideous face. Only a few wore luxurious clothes with a face similar to human.

The two can no longer approach. There is only one entrance to the city.

Yu Tu handed the coat of arms to Yu Mu, and began to calculate the distance and determine the location. Here, the soul's ability to perceive can accurately judge the environment and the location of the person, ensuring the safety of the flashing location.

With the help of the power of heraldry, after successfully jumping over, they were lucky and there were no accidents.

The area selected by Yu Tu is in a small room. It just happens to be able to collect some city intelligence.

The decoration of this room is monotonous. Although it is not a reef-made house, it still looks crude. In the corners of the room are piles of cleaned fine shells, and on the other side are some handicrafts made of shell pearls. It looks like someone’s studio.

After Yu Tu and the two checked for a while, Yu Tu found the problem.

"what happened?"

Yu Tu frowned, opened her mouth and took a breath. Doing this kind of action underwater is no different from looking for death. Even a strong like Yu Tu will have discomfort due to his body structure.

But now, Yu Tu doesn't feel the slightest. The water flow into the body immediately decomposes into gas, which is no different from normal breathing. When they were moving just now, they didn't feel any obvious resistance either.

Yu Mu also noticed this. Both of them thought of that strange barrier.

If this change is due to the barrier, then the problem is coming. Why does the mermaid set up this kind of enchantment? For them, this measure is totally unnecessary. This is more like for ground creatures.

Yu Tu recalled what she saw and heard on the road, and thought of those special mermaids.

"I have a bad guess."

"what have you found?"

"Go to the murloc's palace once and you will know it. If my guess is true. It is very likely that I will choose to ruin this place."

After Yu Mu heard this, she frowned. He really couldn't figure out what could make Yu Tu say such cruel words. However, he believed in Yu Tu's judgment.

The two quickly left the room and walked towards the mermaid's palace.
