The building that looks like a royal palace doesn't cover a large area, and it looks like it's about four square kilometers, but there are a lot of mermaids inside, and it seems that they are busy going in and out. And Meng Yuan also quietly touched in under the cover of the stealth equipment.

The scenery inside is very different from the scenery outside, it seems to be a lot darker here, but the decoration seems to be more luxurious, although Meng Yuan doesn't know what those decoration materials are, but it seems that it should be a priceless thing, at least it has to be a special product under the sea. The inside was actually not complicated, Meng Yuan casually threw out some miniature detection robots and probed the building structure inside.

The building is not too big, and there are not too many rooms inside, except for the middle hall, there are only four halls on the left, right, back, and below. And the pictures transmitted back through the microrobot, Meng Yuan can already confirm the role of these halls. On the left is a large number of adult mermaids, who appear to be the guards of the building, and on the right, there are a large number of little mermaids, unleashing magic or looking at what looks like books, and it is clear that the role played here should be similar to that of a college or school in the human world. The back room is relatively small, and divided into several small rooms, there are not many mermaids in it, but they are very gorgeously dressed, and it is obvious that they should be the patriarch and family of the mermaid group. As for the floor below? The inside was very huge, and there were equipment and treasures everywhere, as well as many glowing gems, just like what Meng Yuan saw outside, it was obvious that this should be a treasure trove of mermaids.

The mermaid's building is very special, their building has no doors and windows, only a hole~ So Meng Yuan easily came to his first stop, the mermaid treasure house.

There are no guards here, and the mermaids seem to be at ease here. Think about it, this place is the center of the city, and it is located on the lower level of the palace, so it is impossible for the enemy to come here, if it really hits here, it is estimated that there is no need to have guards to play a small role, so in the eyes of the mermaid, it seems that there is no need to waste troops to defend here.

But what the mermaid thinks of Meng Yuan doesn't know, he only knows that his chance to get rich has come. Every item here was a magic item, and even those glowing gems and the like had magic fluctuations, so Meng Yuan waved his hand very unceremoniously, releasing a few undead soldiers, and then they began to silently carry out Meng Yuan's order.

Every time the soldiers brought over a batch of items, Meng Yuan had to wave his hand once, and in four hours, Meng Yuan's arms began to go numb~~

"Human! How did you get here? ”

Suddenly, the voice from behind Meng Yuan startled Meng Yuan, in fact, this can't be blamed on Meng Yuan, mainly because it has been here for four hours, Meng Yuan has not found the mermaid coming, so he slowly relaxed and concentrated on his own glorious cause, who would have thought that at this time, suddenly a mermaid who does not know whether to live or die will come here!

That's right, in Meng Yuan's eyes, it just doesn't know whether it is dead or alive, and it is just a matter of him running away when Meng Yuan doesn't find out, not only does this thing not run away, but it still dares to say hello to Meng Yuan? Aren't you afraid that Meng Yuan will kill the fish and destroy the mouth?

Meng Yuan looked back at the mermaid behind him, it was very beautiful, in fact, the mermaid clan was actually quite beautiful regardless of whether it was a female or a male, the difference between them was only in the chest. Females have breasts, males do not. And the mermaid standing behind Meng Yuan was a female mermaid, with a beautiful voice and a very good-looking appearance, staring at Meng Yuan with great curiosity.

"Hehe~~~"

Meng Yuan smiled, but he didn't answer the mermaid's question, but quickly rushed to it under the other party's incredible eyes, and then slapped the back of the head~~~~

After Meng Yuan threw it into the small world, he turned around and ordered, "Hurry up!" ”

The undead didn't speak, but they were faster, and in just twenty minutes, they placed all the items in the treasure house in front of Meng Yuan, and Meng Yuan also threw these treasures into the small world with a wave of his hand. And at this moment, the treasure house~~ It is estimated that there is not even a small shell left, and this place has been completely emptied by Meng Yuan.

Meng Yuan didn't hesitate, because he knew that time was running out, whether it was the cannon fodder outside or the mermaid that Meng Yuan had captured just now, Meng Yuan was not allowed to drag it down, so Meng Yuan set off incognito again after putting away the undead soldiers, heading towards the second target.

The second target is also the main goal of Meng Yuan's visit this time, that is, to grab the Little Mermaid! But don't look at them as just little mermaids, if you want to capture them, it will still be very difficult, because as long as a mermaid escapes or attracts the attention of other mermaids, the consequences are unbearable for Meng Yuan. Therefore, Meng Yuan's operation used some means, such as paralyzing drugs? Drugged? Psychotoxins? Wait a minute.

Anyway, there's only one entrance. Meng Yuan only needs to release the paralyzing agent at the door, and after the mermaids inside are dizzy, he will start to catch them one by one!

Soon, Meng Yuan's paralyzing agent was thrown in by the other party without preparation, and they all cooperated and went limp one by one.

After seeing this scene, Meng Yuan showed a smile: "Ke'er! Well done! This paralytic agent you developed is very good! ”

Ke'er said: "Thank you master for the compliment, the purpose of developing this powerful anesthetic was to paralyze those dragons in the Dragon Country." Therefore, the effect of this anesthetic is stronger, although the effect will be slightly reduced due to dilution in the sea, but it is still more than enough to deal with these fish. ”

Meng Yuan nodded and didn't ask any questions, because time was pressing, so after Meng Yuan waited for the last fish in it to be paralyzed, he immediately released his undead army again and moved them in front of Meng Yuan one by one.

"Human! You are ~~~"

Bang~~~

After Meng Yuan slapped the other party unconscious, he waved his hand and put it into the small world. And when Meng Yuan did all this, the undead soldiers also completely cleaned the room, and even the things that looked like seats were removed. Meng Yuan only left them with two empty rooms.

This time, Meng Yuan's evacuation went smoothly, because the mermaids didn't know that their nest had been emptied by Meng Yuan, and they were still silent in the joy of their victory. When Meng Yuan completely left the city, Meng Yuan's last cannon fodder outside was also blasted into slag.
