Upon entering the stone gate, the mission progress suddenly jumped to 25%.

Yun Si Ning was taken aback.

"It seems this really is an important place."

Here, the light seems to be swallowed up by the thick stone walls, leaving only a deep shadow.

The humid air permeated every corner, carrying an indescribable dampness, as if water could be wrung out of the air.

The swirling mist made Yun Si Ning feel as if a thick, damp cloth was being deposited in her lungs with every breath, causing her immense discomfort.

She walked slowly deeper into the area, where the stench in the air grew stronger.

"This Si Yiqi is really something..."

"If I were buried in this place, I'd stink to death even if I didn't die."

Yun Si Ning tried to scan her surroundings with her divine sense.

But to her surprise, her divine sense, which could originally cover hundreds of meters, was now sealed off within half a meter of her body.

Feeling a little uneasy, Yun Sining gradually slowed her pace.

Suddenly, a strange voice rang out in the distance.

The sound was like something constantly wriggling, accompanied by a slimy, sliding sound.

Yun Si Ning cautiously walked towards the direction of the sound, taking each step with utmost care.

Finally, she could see the creature that made the sound.

In an instant, Yun Sining almost vomited.

It was a huge and conspicuous white cocoon, like an abrupt, foreign object, forming a stark contrast with the surrounding darkness.

The surface of the cocoon is covered with a slippery, translucent film that gives off an ominous pale sheen.

It kept wriggling, as if something inside was struggling to break free from its restraints.

Each wriggling motion was accompanied by a screeching sound that sent chills down your spine.

The cocoon was covered in a sticky substance that shimmered eerily in the dim light and emitted an indescribable stench.

"Is this a slug cocoon?"

"No, I mean, do slugs have a cocoon stage?"

There was no time to consider whether it was scientifically sound; the enormous cocoon gave her a very dangerous feeling.

"No, no, this place is too eerie, let's get out of here."

Just as she was thinking this, a loud rumbling sound came from behind as a boulder scraped against the ground.

"broken!!"

Yun Si Ning was shocked and turned to run outside without saying a word.

But just as she turned around, the giant door slammed shut with a deafening roar.

Oh no, oh no, oh no!

Yun Si Ning knew something was wrong.

Just then, a voice came from inside the huge cocoon.

"Master, is that you back?"
