I woke up to find myself as the villain's older sister.

Chapter 171 Palace Formation

"How could that be?" the mermaid princess laughed. "Although our mermaid race is weak, our sense of territory is extremely strong."

"How could we possibly allow other ethnic groups into the palace so easily?"

"Hmm?" Yun Qingyi turned her gaze back to the crystal fish swimming happily in front of her, somewhat surprised: "Are small crystal fish and jellyfish included as well?"

"Of course," the mermaid princess said nonchalantly, "after all, we must absolutely guarantee the safety of the mermaids."

"You guys have a pretty high level of safety awareness." Yun Qingyi raised an eyebrow. "But does that mean this little creature that's been enchanted is absolutely safe?"

"Hehe." Upon hearing this, the mermaid princess smiled mysteriously and whispered, "Theoretically speaking, it is absolutely safe, but in reality, no defensive layout can be absolutely safe."

"Uh... why do you sound a little excited?"

"Hmph." The mermaid princess put her hands on her hips, curled the corners of her mouth, and glanced at Yun Qingyi, saying mysteriously, "It's not time yet. I will tell the seniors later."

Yun Qingyi nodded and didn't say anything more.

The group followed Uncle Shang down the long corridor. When they passed the second room, Yun Qingyi paid special attention to the mermaid princess and noticed that her body stiffened slightly. Then she pretended to be nonchalant and continued walking with them.

Yun Qingyi didn't ask immediately. She followed Uncle Shang to the top floor, which was even more luxurious than the first floor. The rooms on the huge top floor were not as densely packed as those on the first floor.

Instead, there are more jellyfish and crystal fish like those on the first floor, and the varieties are more diverse. The palace walls are also decorated with various sparkling gems.

……

At first, Yun Qingyi didn't think anything of it, but now she realizes that it seems the merfolk like to decorate their residences in a dreamlike way.

"How about it? Aren't you stunned?" The mermaid princess proudly raised her chin and said to Yun Qingyi and the others, "Hehe, I really envy you, senior. You were assigned such a good room as soon as you arrived. You know, rooms like this, which were carefully decorated by successive mermaid emperors, are becoming increasingly rare."

"Since the successive Mermaid Emperors arranged these things, do the Mermaid Emperors still need to do these things?" Upon hearing this, Yun Qingyi directly seized on the key words and asked.

"Hahaha." Before the mermaid princess could speak this time, Uncle Shang laughed and said, "Actually, it wasn't all arranged by the mermaid emperors. Of course, the design of the palace would be left to professional mermaids."

The Mermaid King merely set up multiple arrays within it.

"An array?" Upon hearing this, Yun Qingyi and the other two suddenly became alert.

Seeing that the group's expressions suddenly became serious, Uncle Shang assumed that they had never heard of this thing before and were curious, so he explained, "This formation comes from beyond the Western Sea. I heard that if you can use it skillfully, its destructive and defensive capabilities are immeasurable."

It can even create illusions that blur the line between reality and fiction. The array that the Merfolk have set up in this palace is defensive in nature, effectively repelling invasions from foreign tribes.

"Oh... I see, how amazing." After hearing Uncle Shang's words, Yun Qingyi and the others showed expressions of sudden realization and surprise.

Then Yun Qingyi asked, "Uncle Shang, how did we obtain the things outside the Western Sea? Did our Merfolk clan leave the Western Sea in the past?"

“Or…” Yun Qingyi paused, then continued, “Or perhaps, our Mermaid Emperor ancestors ever went to the Western Sea?”

“This…” Uncle Shang pondered for a moment, then shook his head and said, “No, our Merfolk clan was born and raised in the Western Sea, and has never been anywhere other than the Western Sea.”

After saying that, he added, "Even our emperor is no exception."

"Then there's an array here..."

"The formation here..." Uncle Shang looked around at the dreamlike palace and smiled at the group, "This formation was left to our Merfolk by the races outside."

They also taught us how to use it.

"It's really amazing, actually. Although they are different races, they have a very high degree of similarity to our Merfolk."
