Today's test was another major failure.

Apart from not being cleaned carefully, there was nothing special about room 321. You Yonghuai tried to lift the mattress to check, but he didn't see anything strange either.

Director Dai also had the dormitory manager check each locker, and they all contained normal daily necessities, snacks, and instant noodles.

Just as Ling Xiuqi was about to conduct a thorough search to find any remaining spiritual traces, Dai Quan received a phone call:

"Director Dai, something's happened here! Come quick! There's a human skin here!"

"Where are you? I'm coming right now!" Director Dai's lips twitched, his face full of suspicion, and he hurriedly said.

Even without speakerphone, the man's voice on the other end of the phone was still loud enough for the two people next to Director Dai to hear.

Immediately, the two followed Director Dai and headed to the location of the repairman mentioned on the phone.

Because the students at Wenjiang Middle School have varying levels of academic ability, in order to prevent them from causing trouble on empty floors, Director Dai specially installed iron gates on the stairs above the second floor. Apart from some school leaders who have keys, no one else can get in.

Director Dai led the two through the unlocked iron gate, his expression serious.

He felt that Wenjiang Middle School was becoming increasingly precarious.

Looks like I need to find a new job in advance.

The reason the repairman was sent up to the third floor was because the students downstairs had been complaining that there was a foul smell coming down from upstairs, and that one of the air conditioners might be broken and making a constant buzzing sound.

Director Dai initially thought it was some stray cat on campus that had died in the air conditioner, and didn't think much of it. But when he got to the third floor, a strong, fishy stench hit him.

Old Huang, the repairman, stood outside a classroom, his face pale with fright. When he saw Director Dai and the police arrive, he hurriedly ran over.

"It's right there, inside!"

"Alright, Lao Huang, go to my office and calm down. The police officer will probably ask you some questions later." Director Dai patted Lao Huang on the shoulder and comforted him.

Upon seeing Lao Huang, You Yonghuai and Ling Xiuqi both frowned in unison.

In their eyes, Lao Huang also shone with a bright light.

This represents a profound spirituality.

Ling Xiuqi watched as Lao Huang brushed past him, remaining silent for the time being.

He knew that the other party probably didn't know where these spiritualities came from either.

They don't even know what spirituality is.

Upon entering the classroom, the stench became even more pronounced. The outdoor unit of the upright air conditioner in the corner had been removed and was leaning against the side, while a flesh-colored object was piled on the floor.

Si Xuanyin and Ling Xiuqi were alright; they were just disgusted but could still observe normally. However, You Yonghuai and Director Dai could no longer stand it, and the latter even ran directly into the toilet at the end of the road and vomited.

Ling Xiuqi pinched his nose, grabbed a corner of the fleshy object with one hand, and flattened it little by little, revealing the shape of human skin.

After comparing the photos, Ling Xiuqi concluded that this was the skin of the missing Li Gui.

Lifting the skin off the ground, Ling Xiuqi glanced at the bloodstains inside that were not yet completely dry, then suddenly noticed something and carefully removed a hair from the head area.

"It seems someone once impersonated Li Gui." Ling Xiuqi asked You Yonghuai to help him take out the evidence bag from his clothes, put it away, and prepare to send it for testing along with the human skin.

"Director Dai, could you please bring over a large, opaque bag?" Ling Xiuqi called out towards the door, but no one answered.

"I'll go take a look," You Yonghuai said hastily, unwilling to linger in the classroom filled with the stench of fish.

Just as he left the classroom and stepped towards the restroom, the pair of ten-sided dice suddenly appeared in front of You Yonghuai:

Search Test: A value greater than 50 indicates a successful test.

Test result: 51

[Test successful!]

Before he could even rejoice at the successful test, You Yonghuai had a sudden thought and subconsciously looked up, only to see a dark figure filled with spiritual energy suddenly emerge from the toilet.

"Officer Ling! There's an enemy!" You Yonghuai shouted immediately.

A sudden gust of wind, like the howling of ghosts and wolves, arose, and a gust of wind brushed past You Yonghuai and quickly locked onto its target.

The dark figure tried to run downstairs, but the iron gate downstairs remained closed.

Before they could change course, Ling Xiuqi grabbed the dark figure by the head and slammed it hard against the door.

You Yonghuai rushed into the toilet and saw Director Dai lying on the ground with several fist marks on his face.

After checking his breathing and confirming that he was still alive, You Yonghuai picked up Director Dai with one hand and walked out of the restroom.

While marveling at his own strength, You Yonghuai looked at the stairs next to the toilet, where Ling Xiuqi was pressing down on the figure with one hand while making a phone call to call for backup.

Ling Xiuqi's gaze lingered on the man whose face was pressed against the iron gate, feeling as if he had seen him somewhere before.

Just as he hung up the phone, the bell rang to signal the end of get out of class. Ling Xiuqi and You Yonghuai exchanged a glance, their lips twitching.

To facilitate installation and save costs, Director Dai installed an iron gate similar to those in prisons, with no obstructions, allowing a direct view behind the gate.

Within seconds, the students who came out of the classroom saw Ling Xiuqi behind the iron gate.

"Holy crap, there are police here."

"Holy crap, isn't that Principal Ma?"

Amidst the exclamations of "Holy crap!" from the second-year high school students, Ling Xiuqi glanced again at the middle-aged man he had pinned down, and then remembered the source of the sense of familiarity.

"You're Ma Yuanjian, the previous principal of Wenjiang?"

The middle-aged man did not reply, but continued to struggle. He was very strong, not at all like someone who was about to enter old age.

After reciting the incantation in a low voice and confirming that the other party was not a puppet, Ling Xiuqi asked You Yonghuai to come over and help him handcuff Ma Yuanjian.

"I remember you were already dismissed, weren't you?" Ling Xiuqi asked, holding down the struggling Ma Yuanjian. "What are you doing here now?"

Ma Yuanjian remained silent, only struggling relentlessly.

You Yonghuai put on the handcuffs and wiped the sweat from his forehead.

Ma Yuanjian was very strong; even someone with a strength level of 30 had difficulty suppressing him.

Moving his slightly sore wrists, You Yonghuai looked ahead, and for a moment, a hint of self-doubt flashed in his eyes:

"Officer Ling, why don't you take a look at these students? I think I'm seeing things."

Before he could finish speaking, Ma Yuanjian, who was being pressed against the iron gate, struggled even more violently.

Regardless of the risk of injury, he relentlessly pounded against the iron gate.

While pressing Ma Yuanjian down firmly, Ling Xiuqi looked up.

In my field of vision, almost all the students exuded a strong spirituality.

Si Xuanyin also looked up, and then, as if something suddenly exploded in her mind, she remembered a sentence her biology mother had once said:

"Human beings rich in spirituality are the best material for rituals..."
