Dormitory group chat, my information updated daily.

Countless faces are covered on the creeping exterior walls of the teaching building.

Those faces were sobbing and wailing, emitting howls like vengeful ghosts that sent chills down one's spine.

"It's over..."

Chen Xiaoyun shook her head and sighed softly.

"What do we do now? Go and rescue them?"

"Save them? How?"

Meng Yao was speechless for a moment, then saw Chen Xiaoyun silently pick up her backpack.

"Are we just leaving like this?"

"What else? Should we risk our lives for four guys whose fates are unknown?"

"But...but Xiao Yun did save us!"

Chen Xiaoyun paused for a second, then shook her head:

"That was their own choice, and it was agreed beforehand that we would just wait here and leave if anything unexpected happened."

This was a plan personally devised by Xiao Yun; it wasn't that she was abandoning him to his death.

Even if Su Muqing finds out, she can't be blamed.

She quickly packed her things, and after taking two steps, she suddenly frowned and turned back:

"Yaoyao, aren't you leaving?"

"I...I feel I can't just leave like this."

Meng Yao bit her lip, her body trembling slightly.

Although she was terrified, and although she knew she was of no use here.

However, as a companion, she couldn't just abandon Xiao Yun and his group.

"Whatever..."

Chen Xiaoyun sighed softly, then turned and left.

It will be dark in three or four hours, and if we don't hurry back, we'll have to spend the night in the jungle.

She's still young and doesn't want to die.

"Hey, Xiaoyun, when you get back, remember to tell Sister Su and Minister Lu about the situation here and ask them to bring people over to help."

"Um……"

Chen Xiaoyun left without looking back. Meng Yao sighed softly, turned to look at the teaching building, and prayed softly:

"I hope you all return safely..."

Inside the teaching building, the group was somewhat at a loss in the face of the sudden change.

"The roads outside have completely changed, even the floor we're on has changed!"

Ji Mingyu's face was grim.

Wang Tianyuan pulled an arrow from the wall, his brow furrowed.

"Is this thing human or ghost? Why doesn't it have a health bar?"

As we all know, monsters with health bars can be killed, but those without health bars... well, that's another story.

The group all turned to look at Xiao Yun, wondering what good idea he had.

Xiao Yun lowered his head and pondered, then secretly opened the preview information panel.

"We still have two chances; hopefully we can get information to help us get out of this predicament."

[Ding! Specified information—'Teaching Building' 'Ghost'—in information retrieval in progress...]

[Ding! Message has been refreshed... Duplicate messages have been removed]

[Preview Information - Activated Teaching Building (Area/Secret Realm/Monster): A building infested with ghosts. Due to the long-term erosion by the ghosts' eerie mental characteristics, the originally inanimate building has gained consciousness. After absorbing the consciousness of all the ghosts in their previous lives, it is filled with extremely complex emotions towards the living.]

[Regional Characteristic 1 - Activation: After activation, all objects will have powerful regenerative abilities, and all inanimate objects in the school building are extensions of this ability.]

[Regional Characteristic 2 - Academic Work: All living beings entering the teaching building must follow its rules and complete the assignments it sets, or they will be punished.]

[Regional Feature 3 - Teaching and Learning: Although it may seem a bit strange, this is actually a teaching building, a place for teaching and learning. As long as you follow the rules, you can learn a lot here.]

【Regional Feature 4 - Soul Sanctuary (Unlocked): When someone helps all the wandering spirits here find their 'true selves,' this place will be transformed into a special region called 'Soul Sanctuary,' and the person who performs this feat will gain the talent 'S-018 - Soul Sanctuary'】

[Solution to break the secret realm: 1. Simultaneously destroy and activate all matter and ghosts in the teaching building; 2. Complete all 'lessons' and pass the graduation exam; 3. Learn 70% of the knowledge stored in the teaching building and pass the teacher qualification exam to obtain teacher privileges; 4. Help all ghosts regain their 'true selves']

[Monster's Weakness: The activated school building is merely a shell; attacks on the building's physical form are ineffective. Its true form is a massive aggregate of spiritual energy; skills effective against the spirit can damage it.]

Following an ancient ritual from memory, the revitalized teaching building gave itself a 'true name' upon its birth. Calling its true name summons its true form, breaks its invincibility, and renders all attacks received as true damage. Its true name is…

Looking at those 18 mysterious numbers, Xiao Yun's expression was complicated.

Who would be so kind as to make up an ID number and use it as their real name?

"The only problem now is that we don't know how thick that spiritual entity's health bar is. Judging from its current level of power, even if we utter its true name, we probably won't be able to kill it."

"Therefore, the only way is to temporarily suppress the trauma, or rather, control it, and then find a way to escape..."

The space in the teaching building was constantly changing. Just as Xiao Yun was hesitating whether to use the forecast information to explore a way out, Ji Mingyu's voice suddenly rang out.

"What's wrong, Ayun? Have you found a way out? You seem to be having some kind of difficulty?"

After pondering for a moment, Xiao Yun briefly shared the information he had obtained and his general escape plan with the others.

"Do we need a way to get out of here quickly? Ugh! I remember that mage dropped a random teleportation item; we could use that!"

Xiao Yun's eyes lit up, but Ji Mingyu shook his head:

"No way, who knows where the random teleportation will send us? What if we end up in a worse place than here? We're doomed!"

"Then what do you suggest we do?"

Xiao Yun looked at him, only to see a mysterious smile playing on Ji Mingyu's lips.

Isn't that a coincidence? He just checked in and got a new good item.

It's just that the conditions for its use are somewhat demanding; it can't be affected by external forces, otherwise he would have already led his brothers away.

But now Xiao Yun has a way to control this monster, so there shouldn't be any problem.

"You just need to control it, and I'll handle the rest."

"You'd better have some skills..."

Xiao Yun sighed softly; at this point, there was no better solution.

Rumbling--

The shattered library is slowly being restored, countless faces roar angrily, and countless voices whisper in their ears, urging them to go to class.

The feeling of death grew stronger and stronger; there was no time to hesitate.

"I'll say its real name now. The moment it appears, I'll relinquish all control and buy time for Lao Ji."

The others nodded, and Xiao Yun took a deep breath and recited the eighteen mysterious numbers.

Boom boom boom—

The school building shook violently, and a ghost appeared before them.

Its face constantly changes, but its eyes are incredibly lively, a sign of consciousness.

"How...did you know?"

Before he could finish speaking, several stun grenades flew in graceful parabolas and exploded overhead.

boom--

The moment it explodes, a dizziness effect occurs.

No damage was caused, but a health bar appeared above its head.

"efficient!"

Wang Tianyuan cheered, and at the same time, Zhong Mo raised his golden eyes.

After killing the golden beast, he gained the [Intimidation] skill, but this skill mutated in his case.

In a daze, it seemed as if a ferocious dragon head emerged from nothingness, roaring loudly.

【Dragon's Might】!

In Xiao Yun's eyes, the lines of runes crisscrossed, releasing [Mana Vibration] while simultaneously activating the Myriad Manifestations True Understanding.

After unleashing a series of skills, the spiritual energy bar of the revitalized teaching building was significantly reduced.

Boom boom boom—

The school building shook violently, and countless voices cried out in anguish.

Its face changed rapidly as it let out a furious roar.

"The boss is furious! Lao Ji, are you done yet?!"

Cold sweat beaded on Xiao Yun's forehead. Ji Mingyu didn't answer, but instead bit his finger and made the final stroke on the intricate runes in the air:

"Open Sesame!"

boom!

The dark doorway opened wide, and without any hesitation, the group rushed out.

"Don't leave!"

The spirit entity, regaining its senses from the control chain, roared and reached out to pull Xiao Yun and his group back.

However, it was still too late.

"Never again."

Xiao Yun and the others waved, and the gate slowly closed.

Just as everyone breathed a sigh of relief, a cold snort suddenly rang out.

Four streaks of light flew out from the crack in the door and wrapped around their wrists.

"Holy crap! What the hell is this?"

Wang Tianyuan cried out in alarm and frantically shook his hands, but he couldn't remove the rune chains wrapped around his wrists no matter what he did.

"We... seem to be cursed."

Xiao Yun looked at the system pop-up window that appeared in front of him, his expression complicated.
