In fact, Xi Xi spent a long time painstakingly drawing the ointment, and she was almost questioning her life choices...

The game's "Miraculous Brush" couldn't recognize the ointment she drew, as if medicine was a rare item in this game world. Even the system's resource library was confused, mistaking it for a square mirror.

What's even more infuriating is that when Xi Xi finally managed to identify the ointment after going through countless hardships, the system stingily only gave her one ointment.

What a loss! It's such a huge loss!

She could easily draw a decent-looking weapon and exchange it in the public chat; surely she wouldn't only get a single ointment in return!

Xi Xi was immediately furious.

However, now that she had finally calmed down, Xi Xi had a new idea. She guessed there were only two possibilities: either the basic medicine was really very rare, or there were other treatment methods in the game...

But that's a story for another time.

To save time, the three of them got up early in the morning, ate only some biscuits, and hurriedly set off.

Xi Xi calmly placed the magnetic mechanism box into the stone trough. The next second, the water in the stone trough began to seep in, flowing into the gaps of the magnet at a steady rhythm.

Xi Xi pushed the magnets in the stone trough and found that the magnets could actually move!

What does that mean? Does it need to be decrypted?

Xi Xi couldn't help but frown. She wasn't very good at playing with these kinds of puzzle boxes. Even with Rubik's Cubes, she only knew some basic formulas. She had no idea how to solve anything more complicated and could only rely on luck to figure it out.

"How about I give it a try?" Sallyman stepped forward, staring thoughtfully at the stone trough in front of her.

The underground passage was really narrow, so Xi Xi took a step back and made room for Shaliman. Just as her back touched the rock wall, she suddenly felt something strange.

Xi Xi looked back from a distance, and the azure light emanating from Chu Zhiqin immediately shone on the stone wall, which was intricately carved with patterns and hieroglyphs.

She reached out and touched it, her fingers lightly tracing the runes on the surface. Xi Xi said to Shaliman with some surprise, "These runes are most likely related to the pattern..."

Sallyman turned to look at the wall, her gaze slightly lowered as she carefully observed every detail. She discovered that the runes were not arranged randomly, but rather followed a certain multiple pattern and logic, echoing the patterns on the wall.

So the three of them divided the work: Chu Zhiqin started counting the points on the runes, Xi Xi searched for the corresponding patterns, and Shaliman calculated and deciphered the placement of each magnet.

As time went by, a sudden "click" sound came from the magnet, and the stone trough, permeated with water, began to emit a dazzling light.

Immediately afterwards, a low, mechanical hum sounded from not far away, and the cellar door slowly opened, revealing a hidden passage.

"It worked!" Sallyman couldn't help but cheer, then realized she had been too loud and her cheeks immediately turned bright red.

Xi Xi and Chu Zhiqin couldn't help but laugh out loud.

After spending these days together, Xi Xi gradually got used to Shaliman's personality, which was completely different from her appearance, and couldn't help but smile.

“This is the first time I’ve ever seen you laugh so loudly.” Sallyman looked at Xi Xi with some surprise.

In her memory, Xi Xi always had a cold face, and even when she smiled, it carried a hint of coldness and a sense of aloofness, so seeing Xi Xi smiling so brightly now was a complete surprise to her.

Upon hearing this, Xi Xi's upturned lips instantly returned to their usual composure. She was startled, and a hint of doubt arose in her heart.

Does she really not smile much? She doesn't know.

It feels like the last time I laughed without any restraint, freely and joyfully was a lifetime ago.

Seeing Xi Xi's face turn cold again, Sallyman looked over with some concern: "Did I...did I say something wrong...?"

"No." Xi Xi glanced at her, her tone deliberately light, before stepping into the cellar. "Next time I put up the Laughter Charm, I'll have you guard the door."

Sallyman followed, somewhat confused. Chu Zhiqin, who was walking at the back, understood why Xi Xi was so preoccupied, and a hint of heartache flashed in her eyes.

But when the three of them stepped into the cellar together, their eyes were filled with terror, and they could no longer laugh or talk.

The air in the cellar was filled with a damp, musty, and ancient scent, as if every inch of the space bore the heavy breath of time.

A strange tree grows upside down in a way that defies the laws of nature!

Its roots did not penetrate deep into the earth; instead, they went upwards, tightly entwining themselves and embedding themselves in the crevices of the rocks at the top of the cave.

Those thick tree roots, like twisted giant pythons, coiled at the top of the cave, providing incredible support for the tree's survival.

The tree's branches and leaves, as if forgotten by gravity, freely soared upwards.

These branches and leaves are not lush, but they are exceptionally resilient, both vigorous and powerful, and possess an indescribable, eerie beauty.

They flamboyantly sway in the air as if they possess consciousness, occasionally emitting a faint friction sound, like a whisper, which sends chills down one's spine.

Even more horrifying, countless human bones were scattered around this upside-down tree.

These bones, some intact and some broken, some piled together and others scattered on the ground, seem to tell one tragic story after another.

Each bone reveals the vicissitudes of time and the fragility of life, forming a stark contrast with this strange tree, clearly a victim of its growth.

And those branches that stretch out in all directions seem ready to snag new flesh at any moment, dragging innocent lives into this realm of death.

“This is a mirror tree…” Xi Xi’s face turned pale. She immediately understood that the disfigured stone statue was not an octopus monster, but a strangely shaped tree!

And those outstretched tendrils are the tree's branches spreading out in all directions...

Sallyman was so frightened that she trembled all over. She forced herself to endure the discomfort and pointed to the thick branch in the corner of the wall.

Xi Xi and Chu Zhiqin looked over upon hearing the sound, and their expressions froze instantly. The corpse that was wrapped and curled up by the thick branch was none other than Wei Chenghao!
