After forming a covenant with the interstellar bosses

Song Yu looked around Wu Lingjiu's palace, using tree branches to help her walk. She was very fast and soon she had finished touring the palace.

The interior is decorated in a similar style, and the areas outside that are not part of the palace and do not have water curtain walls are pitch black with no end in sight.

Everything seemed very primitive until she found the invisible camera in the corner that Wu Lingjiu had placed in the bedroom of Bai Ze Palace. She found that there were many here as well. Then Song Yu noticed the many large and small devices hidden in the water curtain, under the shells, and in the dark corners.

Seawater filter, water curtain energy system, temperature control device...

If the mermaids had not found these underwater equipment in the human world so accurately, then they could have made these technological products themselves.

These should be relatively low-end, because the two female mermaids who followed her did not react to her inspection of these devices. They seemed to be just ordinary small appliances.

Until she saw a metal door that didn't belong here, like the sealed heavy metal door of an operating room or laboratory in a hospital.

"What is this place?"

"You can't go in." The mermaid held a spear in her hand and was on guard. She didn't have the relaxed feeling like Wu Lingjiu.

She looks a bit like Wu Lingjiu, with black hair and fair skin, but not as sickly pale as Wu Lingjiu.

"What if I want to go?" Song Yu asked, and she made a gesture to push the door.

The mermaid held the spear in her hand across Song Yu's face and said, "Don't push your luck, you'll regret it."

Song Yu didn't have to go in and take a look. She just wanted to test the bottom line of these mermaids. She stretched out a branch and easily controlled the mermaids. Song Yu then discovered that the two mermaids left by Wu Lingjiu were only D-level.

She thought they were guards called maids, but apparently, they were just maids.

Song Yu controlled the two maids separately. She tried, but the door was locked and she couldn't open it.

"Sister, do you want to go in?"

Just when Song Yu was studying the door carefully, Wu Lingjiu came back.

Song Yu was startled, and then let the two maids go embarrassedly.

"Your Highness, this human is trying to break into the secret room. You cannot let her do whatever she wants."

Suddenly, a black mist appeared in Song Yu's eyes, and the two female mermaids disappeared with the black mist.

"Anyone who dares to use a weapon against my sister must die."

"You put them..."

"Throw it onto a star."

Dead? Song Yu's hair stood on end. Wu Lingjiu, who had always been like a child in front of her, was almost letting her down. But it was okay. This could be considered a reminder to her.

"Are you angry?" Wu Lingjiu seemed frightened. "Then I won't kill them next time."

"Hmm." Song Yu remained silent. She didn't need to speak for the mermaid. She was just surprised that Wu Lingjiu still showed no mercy to his kind. She pointed at the door and asked, "What's in here?"

Wu Lingjiu shook his head. "I don't know. My father doesn't allow me to go in. He said it's very dangerous inside. And my spatial ability can't penetrate this door."

"You can't go in?"

Wu Lingjiu shook his head, then he happily showed Song Yu his harvest.

"Look, sister, I hunted a lot of high-grade seafood, including a Grade A giant squid. Let's grill it later."

"Okay," Song Yu could only agree, and then asked tentatively, "Does your father have other mermaids living here? I didn't see anyone just now."

"This is my palace. They each have their own palace," Wu Lingjiu said. "Only the royal family and the royal slaves can live in the palace. The other mermaids are in the city."

"City?"

"Well, you have cities, and we do too, but we don't have so many tall buildings because we live in the water. When I have the chance, I'll take you to see them."

Song Yu was indeed curious about the mermaid city, but she didn't want to go there wrapped in bubbles.

"I'm tired, let me rest for a while." Song Yu said.

She was really tired. There was no concept of time in the deep sea, and she didn't even know how long she had been here.

"Just sleep in my room. You sleep on the bed and I'll sleep next to you." Wu Lingjiu said happily.

Obviously, Song Yu didn't want to sleep in the same room with Wu Ling for a long time, but she didn't want to offend this mermaid.

Song Yu followed Wu Lingjiu back to his bedroom. Wu Lingjiu got a quilt from somewhere and brought it to her wrapped in a bubble, then put it into her bubble so that Song Yu could cover herself with the quilt.

Song Yu lay down awkwardly, but Wu Lingjiu seemed to remember something. He ran out and came back with a bunch of chains in his arms.

Song Yu was on guard. She had locked Wu Lingjiu in the same way when they were in the underground prison cell of Bai Ze Palace. Now the retribution was finally coming upon her.

Opening his eyes resignedly, Song Yu knew that struggling was futile and he almost reached out his hand, but at this moment Wu Lingjiu locked the chain on his arm, and the other end was buckled into a ring on the headboard of Shell Bed.

"you……"

"You said you'd only sleep soundly if you locked me up next to you," Wu Lingjiu said. "Don't worry, this is much better than those unreliable techniques of yours. Yours lost its effectiveness after nearly eight hours. Mine has no time limit. Anyone locked up by it won't be able to use any abilities, and I can't escape either."

After saying that, he handed a triangular slice to Song Yu.

"Here, this is the key. You can only open it when you wake up." Wu Lingjiu smiled and said, "Sleep peacefully, sister."

Is this a habit? Song Yu couldn't believe it, she stroked the key.

Wu Lingjiu curled up at the head of the bed, resting his head on the edge, his hands hanging on his legs, and fell asleep while sitting.

Really fell asleep.

Song Yu could kill him now with just a sharp branch. Of course, if she killed Wu Lingjiu, she herself would surely die, as there was a mermaid king here who was at least SSS level.

She suddenly raised her hand and touched Wu Lingjiu's head unconsciously. The other party rubbed it subconsciously and muttered something indistinctly. Surprisingly, neither of them found it strange.

I don’t know when Song Yu fell asleep. In the dark seabed, there was an SS-level monster beside him whose intelligence was no less than that of humans.
