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

"These pills..." Yun Qingyi took the bottle, poured the pills into her hand, there were four in total, but they vaporized into the air in just a moment.

"It seems that too much time has passed and the effects of the medicine have worn off," Ji Zhaoze said.

Yun Qingrou looked around. "It seems there's nothing here except this bottle of pills."

Undeterred, Yun Qingyi continued wandering around, even knocking on every single brick, before finally accepting reality with a regretful expression: "There really is nothing there."

Well, it wasn't a complete loss. The Thousand Illusion Mirror was the biggest gain. Yun Qingyi felt a little better after thinking about it, and returned to the location of the mural with the two of them.

"Seniors, you're finally back!" Upon seeing Yun Qingyi and the others, the mermaid princess excitedly sat up from the ground and walked towards them.

The spirit within the mirror shard in her hand exclaimed with delight, "Brother and sister, it's so good that you're all alright! You're really amazing; you managed to escape from that person!"

Seeing her, Yun Qingyi recalled the words of the man from Sanmian Valley, "Lingling, is there something you haven't told us completely?"

"Huh? No..." The girl in the fragment lowered her head guiltily.

Yun Qingyi's eyes were indifferent: "Even if you don't say it, I already know about it, about how you sacrificed to the sea god according to the seven emotions."

A rare hint of panic flashed in the girl's eyes amidst the shards. "Sister, did you know?"

After saying that, she pouted and said, "Brother and sister, I didn't mean to hide it from you, it's just that... he's my clansman. Although I really want you to defeat him and get out of the Three-Sided Valley, I just can't bring myself to tell you his weakness directly..."

"Weakness?" Yun Qingyi's eyes flickered. "What weakness?"

The girl was taken aback: "Don't you know, sister, that as long as you follow the direction of the seven emotions, it's easy to find the corresponding weaknesses?"

"For example, if older siblings experience 'sorrow', as long as you guide them to talk about what they consider to be the saddest thing, they will get stuck in their own sorrow and won't be able to get out of it. At this point, it is easy to cause them harm."

"I see..." Yun Qingyi seemed to understand. No wonder he was so easy to deal with, even though Yun Qingrou and Ji Zhaoze had already laid the groundwork and severely injured that man.

Normally, it would take her a lot more effort to kill him, but she was quite surprised that she only needed to unleash a single bolt of lightning to annihilate him.

If it's as Lingling said, then it makes sense.

As Yun Qingyi and the girl were exchanging words, the mermaid princess was completely confused. "Senior, what are you talking about? What weakness? What tragedy?"

Upon hearing the mermaid princess's words, Yun Qingrou and Ji Zhaoze also looked at Yun Qingyi. Although they had already guessed the general idea, they still wanted to hear the full version.

When asked, Yun Qingyi recounted her conversation with the man.

Upon hearing this, the mermaid princess stared in shock, her eyes widening: "How could it be so cruel?"

Yun Qingyi sighed and said nothing, but recalling those words only added to her heaviness.

Her thoughts drifted far away again. She shook her head and decided not to think about it too much. "Let's go find the next hidden space."

……

After another round of trouble, Yun Qingyi finally arrived at the last place, which was a pavilion above the palace.

“This place… is a little different.” Yun Qingyi frowned as she looked around the pavilion.

“Ah, this is not our Li ethnic group’s territory,” Lingling suddenly said.

"What did you say?"

Seeing that everyone was suddenly looking at her, and thinking that they hadn't heard her clearly, the girl repeated herself: "This is not the territory of our Li people."

"Why do you say that?" Yun Qingyi asked, looking at her.

The girl thought for a moment and said, "I only learned about this by chance. Our Li people used to be on good terms with another race, and this place was reserved for that race."

"So... what race are you talking about...?"

"Mermaids," the girl said.

"Wh...what?" Now it was the mermaid princess's turn to be shocked. She had thought that the atmosphere around her felt so familiar when she came in. So that was the reason.

“We Li people believe that since it is a sacrifice, there should be the presence of good friends, so we specially gave up this place to provide offerings for the merfolk.”
