Lua looked a little puzzled as she put away all the seaweed.

For humans, ingredients in the ocean are rare and rare, but for mermaids, these things are equivalent to steamed buns on the rotten streets of the human world.

Common, not unpleasant, but tired of eating.

"Of course I do, these are all ingredients that can be used to make food." Seagrass is not a valuable thing, but it can only be obtained by going deep into the ocean floor.

There are no fishing in the territory for the time being, so this time the opportunity to collect is not available.

If he hadn't known that this was in the dungeon, Su Yu would have thought that these seaweed monsters would have more of them.

After all, these seaweeds belong to blue quality materials, which is already considered a high grade among the ingredients, you must know that the top and highest ingredients on the market are only purple quality, and they are extremely rare, and there are not many blue quality, more are white and green.

For example, the fruits and vegetables grown in the farmland of the territory are actually white quality, and only a few mutations will be green quality.

Blue quality ingredients have a chance to make purple quality food, and usually this kind of food will also have special effects, which is basically inevitable with Meck's current cooking skills.

"It's very simple if Yuzu likes it, we mermaids have a lot of seaweed, and I'll ask the elder to send you half of it when the time comes." Seagrass is their daily food for mermaids, so naturally they have a lot of reserves, and this thing is also very cheap for them, after all, the bottom of the sea is all over the ground.

Not to mention giving half of it, even if the seaweed in the mermaid clan's warehouse is only one-tenth of Su Yu, it is enough for her backpack to be filled from scratch.

Su Yu was not polite when she heard Luya say this, mainly because she also knew that this thing was indeed worthless to the mermaid clan, so she accepted it gladly.

"Then you're welcome, but I can't take this seaweed for nothing, if you have something that you can get on land, I can collect it for you." The value of seagrass is not easy to define, it is worthless to the merfolk, but for humans, a serving of seagrass can be sold for several silver coins in the market.

Su Yu didn't lack the money for these silver coins, but he still felt that bartering was the most suitable.

"Well, I actually have something I want, like those runes you gave me earlier......" Lua chirped before stopping when she reached her destination.

"This is the treasure house of our merfolk clan, there is the entrance, but it is heavily guarded, and the door needs to be opened with the keys in the hands of two elders at the same time." Although the so-called heavy guards do not exist because of the illusion here, the lock on the door still exists.

Just when Su Yu was thinking about whether to break the door violently, Luya directly and mysteriously led them around the side and back of the treasure house.

"Actually, there's a secret door here that can lead directly to the treasure house!" Luya pointed to a wall and said solemnly.

Su Yu didn't expect that Luya's familiarity with the mermaid clan would really surprise them, but she soon thought of a question.

"It's not appropriate to tell us this kind of thing, right?" This is the treasure trove of the merfolk, second only to the forbidden land.

Luya nodded, and explained without hesitation: "If it was before, then I would definitely not say it, but now the damage is so serious everywhere outside, and the treasure house is also a hard-hit area, so it needs to be rebuilt." ”

Since it is a reconstruction, what Lua told them here will definitely not apply to the outside, and there may or may not be a secret door in the treasure house at that time, but it will never be in this location.

Hearing Luya say this, Su Yu nodded reassuringly.

She actually guessed that the reason why Lua said it was because the treasury was going to be rebuilt, but just because she knew it didn't mean that everyone else knew.

With such a significant benefit, it is difficult to guarantee that none of the people she brought will be moved, and even if they don't do it this time, it's hard to say whether they will talk more when they go back.

So she was ostensibly worried about Lua, but in fact it was to warn them.

"Let's go." Luya didn't think so much, she led everyone to successfully enter the secret door of the treasure house, this secret door is located on a ground in the corner of the treasure house, there is a floor tile with a pattern that is almost indistinguishable from the surroundings, pry this floor tile open, you can see a switch, push the switch, the wall in front of you will automatically open, and there is an entrance that can only accommodate one person at the same time.

"I'll go in first." Luya volunteered to walk in, but before Su Yu could stop her, she found that she had slipped into it like a slippery swimming fish.

"Let's go in too." Seeing this, Su Yu had no choice but to let the others go in immediately and join Luya as quickly as possible.

"I'm not going in." As everyone lined up to enter, Ainita found Su Yu and whispered.

Su Yu glanced at her and didn't ask the reason, just nodded and reminded: "Then you have to be careful." ”

Anita smiled, "Don't worry, there's nothing hurting me in this place." "But if she makes a move, the strength of the derivatives of the illusion will be strengthened, and then Su Yu and they won't be able to deal with it.

On the other hand, if she was here to help guard it, it would at least ensure that the creatures outside would not enter the treasure trove and trap them.

After everyone had entered, Ainita found a random place to sit down, seemingly resting, but the bow transformed with energy was always in her hand.

……

……

"It's finally here, and this is the treasure trove!" Lua shouted happily, then looked back to find that there was no one behind her, and the secret passage that was supposed to get her here was gone.

Luya had a bad premonition in her heart, she actually regretted it a little, knowing that the primary target of this illusion would be herself, but she still walked in the first place so impulsively...... Yuzu: She must be worried about herself right now, right?

"Well, I wouldn't have followed up if I had known...... It's a dragger......" Lua pursed her lips, not particularly scared, because the illusion here was a place she was very familiar with.

The reason why she knew about this secret door was because the eldest prince had brought her here to play when she was a child, and at that time it was a day to play, and sometimes she even forgot to go out.

There are a lot of things in the treasure house, so there are also a lot of 'treasures' to explore for her as a young person.

Once she and her eldest brother didn't go out for three days in a row, and the people in the entire palace were in a hurry, and in the end, the five elders heard from the mermaids guarding the treasure house that there were strange movements in the past two days, and they found out.
