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

Yun Qingrou looked at the wall clock that Yun Qingyi was holding and nodded: "That should be it. I just saw my sister turn the clock and then it came back here."

"Yes, you guessed right, it is indeed related to this wall clock." Yun Qingyi also looked down at the wall clock in her hand.

"I guess this wall clock is the key to leaving this room."

After speaking, Yun Qingyi re-examined the room. Apart from the absence of the wall clock, everything else was exactly the same as when she arrived.

When she adjusted the time, she deliberately turned it back fifteen minutes, back to the time when they arrived, to confirm her idea.

Sure enough, just as she expected, the clock could be set to a different time.

After confirming this idea, Yun Qingyi was still a little confused. Even if they could change the time at will, how were they going to get out?

Ji Zhaoze also looked around the room, and besides finding it somewhat magical, he also thought of this question.

He frowned and said to Yun Qingyi in a deep voice, "Junior sister, I think that since we are going to go out, the key to solving the problem still lies with that mermaid princess."

“I agree,” Yun Qingrou echoed. “Just now, before that Tuso hid in the corner, I exchanged a couple of blows with him. Apart from his sneaky moves, he posed no threat whatsoever.”

At this point, Yun Qingrou curled her lips in disgust, then said seriously to Yun Qingyi, "But during the exchange, I saw some very subtle wounds on his chest and neck."

"Hmm?" Upon hearing this, Yun Qingyi immediately perked up and gestured for Yun Qingrou to continue.

Yun Qingrou lowered her head and pondered for a moment, then said, "Those wounds don't seem to be deliberately concealed. Rather, they seem to have faded over the years due to the influence of other forces."

"But with a closer look, you can find those fatal wounds, and there's more than one."

"So, what Arou means is that Tuso didn't die because of the catastrophe, but died before the catastrophe?"

Hearing Yun Qingyi's words, Yun Qingrou nodded.

The three of them unanimously thought of the mermaid princess, since the only one who hated Tuso and had the opportunity to harm him was the mermaid princess.

Yun Qingyi lowered her head. The hands of the antique clock in her hand were still turning. She knew that as soon as the hands pointed to the middle, the merman on the bed and the room would reveal the danger again, just like when they came.

"Tap-tap-tap-"

Time ticked by, and the intimate sounds of the merman on the bed grew increasingly mournful.

"Let's go," Yun Qingyi said, looking up at the two of them.

"Where are you going, sister?"

Yun Qingyi touched the pointer with her finger and said calmly, "Didn't you say that the key to leaving lies with the mermaid princess? As the saying goes, 'Know yourself and know your enemy, and you will never be defeated.' To find this key, we must first understand the mermaid princess."

After all, everything about her before came from her own mouth; who knows how much she's hidden or how much of it she's lied about?

“So…” Yun Qingyi turned the pointer, “If you want to understand, it’s better to go to the source yourself to find out.”

As Ji Zhaoze and Yun Qingrou were slightly stunned, the space gradually became distorted and blurred.

As they gradually came into view, the three of them changed their expressions. There was nothing beneath their feet, and they fell vertically into the trench where they were.

Looking down into the deep, dark trench, Yun Qingyi wanted to use her spiritual power to swim upwards.

Unfortunately, this trench seemed to possess some kind of magic; not only did spiritual energy have no effect here, but it also seemed to be absorbed by something.

Yun Qingyi's lips twitched. No, their luck was just too bad.

The ocean is so vast, and this location, randomly placed in this strange-looking trench, made her seriously suspect that something was amiss.

Besides, doesn't a wall clock change the time in the room? What are they doing here in this trench?!

Just as Yun Qingyi was feeling indignant, a huge shadow suddenly swam rapidly towards her from the front.

While the group was still somewhat dazed, the shadow lifted them up and, with the flowing water, slowly and leisurely swam out of the trench.

"Are you okay?"

A clear and assertive voice reached the ears of the three.

The light outside the trench was excellent, and the three of them could clearly see the girl's figure.

She had long, deep blue hair and blue eyes, unique to merfolk, and proudly looked at them, swaying her beautiful fishtail, as if seeking praise.

With just one glance, the three recognized the person in front of them.

She was a mermaid princess in her youth.
