A crisp sound of bones breaking rang out as Shen Jue snapped the head of the undead merman, severing its struggle completely.

I never expected this thing to have intelligence.

Just when Shen Jue thought everything was over, a powerful mental shock suddenly erupted from the corpse of the undead merman, sending Shen Jue flying.

Shen Jue slammed heavily against the wall, feeling dizzy and disoriented.

I was careless. I never expected this thing to have such a way of resisting.

When Shen Jue came to her senses, she discovered that the corpse of the undead merman had begun to decompose, turning into a pool of black water that slowly seeped into the ground.

Shen Jue: I'm really impressed, they even went so far as to destroy the evidence.

Looking at the scene he had created, Shen Jue fell into a brief silence.

This situation really surprised her. She wanted to kill the undead merman, but she didn't intend to make it disappear directly.

Shen Jue wanted to investigate further to see if this undead mermaid had any use for her.

Now, the undead merman has turned into a pool of black water.

If you don't look closely, you can seep the black water completely into the ground.

If more time passes, even these traces will be invisible.

It was a real shame that she had squandered such a vital clue. However, Shen Jue didn't dwell on it for long before receiving a notification from the game system.

[Discovered the secret of the Merfolk: The Merfolk King's method of rebirth, progress +10%, current mission progress 80%.]

This hidden side quest gave her a 10% boost, making this exploration trip totally worthwhile.

Thinking about this point, Shen Jue thoroughly sorted out the information she had obtained.

I had a general idea in mind.

Now that the trail of the undead merfolk has gone cold, let's see if there are any other clues here.

Shen Jue carefully examined the secret room.

As she was searching, her gaze was suddenly drawn to a mural on the wall.

The mural depicts a person dressed in a black robe standing on an altar.

At his feet lay the corpses of merfolk, which appeared to have lost all signs of life.

Shen Jue guessed that these corpses were probably sacrifices offered by the black-robed man to some mysterious power.

The purpose of the sacrifice must be to gain the power of rebirth.

Shen Jue continued to observe the murals and discovered that there were also some strange symbols that she couldn't understand painted around the altar.

These symbols looked familiar to her, but Shen Jue couldn't quite place where she had seen them before.

Even if she doesn't know the meaning of the symbol, it doesn't matter. She can take a picture of the symbol as evidence and study it later.

Just as Shen Jue finished photographing the symbols here, the murals on the wall suddenly started flashing, and then the entire room began to shake violently.

Oh no, this place is about to collapse!

Shen Jue realized the situation was bad and immediately turned around and rushed towards the exit.

However, just as she was about to rush out of the room, a huge rock fell and blocked the exit.

Shen Jue tried to push the boulder, but found that it did not budge.

Damn it, she must have accidentally triggered some mechanism. We have to escape before the Mermaid King finds her.

Shen Jue quickly checked his inventory of cards.

After searching for a while, I thanked heaven and earth, and thanked my own foresight, for I still had one of the wall-penetrating cards I had prepared.

Without hesitation, Shen Jue used the wall-penetrating card. Her figure was enveloped by a peculiar energy, and then her body gradually became ethereal.

These rocks blocking her way can't stop her at all!
