Mo Bai put down the documents and let out a deep sigh.

Just reading those words made her feel as if her mind were about to collapse.

Now she understood why Liu Congyi had gone mad after reading it.

This wasn't an ordinary report. Beneath its plain, matter-of-fact wording lay an overwhelming pain.

When Mo Bai read about Gao Siyun's heart being removed, a sharp ache struck her own chest, as if someone had forcibly torn her heart out.

And when she saw that the little girl's heart had been transplanted away, an even stronger urge surged up inside her, a near-mad impulse to destroy the entire world.

On the surface, the report had been written by the Dismemberment Forensic Doctor before he became a monster. But what it truly conveyed were Gao Siyun's emotions.

Just as Gao Siyun had once used that deranged police officer to send out a cry for help, this report was likely written under her will as well. Meant to pass on this buried story and reveal the truth to everyone.

Yet the emotions contained within it were far beyond what an ordinary person could bear. Anyone who read it would be dragged into Gao Siyun's pain, despair, and hatred. Unable to escape, until they eventually broke down, went mad, and began seeing everyone as enemies trying to harm her "daughter." At the end, they would attack people indiscriminately.

The desire to spread the truth was Gao Siyun's will. While the wish to prevent this report from contaminating others was the forensic doctor's.

The document also answered some lingering questions Mo Bai had from the Biological Research Institute No. 7.

She vaguely wondered before: what was the origin of Professor Yang becoming an Ultra-Star Rank monster?

He created such a creature whose extracted fluid possessed a kind of "living" quality. It was capable of granting both living and non-living things vitality that was as potent and dangerous as poison.

So where did this monster come from?

How did Professor Yang cause such a mutation in his own body?

Now she knew. It all traced back to Gao Siyun.

At the very beginning, it was nothing more than a dead mother's desperate obsession with bringing her daughter back to life.

But in this world, steeped in negative flow, that obsession was twisted into something monstrous.

The report was written from the forensic doctor's perspective, which left out many details. Mo Bai could only reconstruct the truth through inference.

Before her death, Gao Siyun's determination to protect her daughter prevented her from resting in peace. She even removed her own heart, hoping it could save her child.

At that time, the only person she could call upon was her husband, Professor Yang.

Hearing his wife's call, he dragged his broken body to the morgue. After taking the heart, he sensed the life force within it.

He himself was close to death. He, too, wanted to live.

So instead of giving the heart to their daughter, he used it on himself.

Betrayed by her husband, Gao Siyun was consumed by fury. Even in death, she refused to close her eyes, pounding the bed with her fists.

It was Professor Yang who calmed her down. He told her that their daughter was still young. If he died, even if the girl somehow survived, no one would care for her. But if he lived, he could find a way to revive their daughter and take care of her properly.

Gao Siyun accepted this reasoning and chose to trust him.

To save her child, she removed her organs once more, hoping her husband would use them to bring their daughter back.

Professor Yang took his wife's remains, but whether he used them on their daughter remained unknown.

He wasn't exactly a bad man, just selfish. He loved his daughter, but he also wanted to live. When forced to weigh his daughter's life against his own, he chose himself.

Mo Bai couldn't truly condemn him. The instinct to survive is human. And perhaps it was precisely because of that universal selfishness that Gao Siyun's love seemed all the more extraordinary.

Professor Yang hadn't completely abandoned the idea of saving his daughter. He continued researching, trying to find a cure.

Unfortunately, this hospital was far from clean. Behind the scenes, it was involved in organ trafficking.

Attached to the report was also a consent form signed by Professor Yang's family, agreeing to donate their organs and bodies.

Before everything happened, Professor Yang had indeed been a great doctor. After his death, he had been willing to donate his corneas, heart, and other organs, and even donate his body to a medical school to teach future doctors.

His wife was just as noble, signing the agreement alongside him. That was why Gao Siyun's body had remained in the morgue instead of being cremated. Once the case was closed, it was to be sent to a medical school.

As for their seven-year-old daughter signing such an agreement, no one knew why. Perhaps the couple had been so idealistic at the time that they had included her as well.

That agreement became the little girl's death sentence.

Once she died or was close to death, her organs could legally be transplanted into others.

And in this hospital, many people had long been waiting for suitable organs.

Even in a normal world, immense profit can drive people to take desperate risks. Let alone in a world filled with malice.

Just like how the Biological Research Institute No. 7 openly conducted human experiments without consequence, and how Count Leon turned people into puppets, this world was disordered and chaotic.

In such a malicious world, monsters were constantly being born, and any event could give rise to one. Ordinary people in this world could become monsters at any moment, or become the victims themselves.

So in this world, the hospital could brazenly transplant Professor Yang's daughter's heart into someone else.

If nothing unexpected had happened, the dead girl would likely have turned into a powerful instance monster driven by hatred. She might have killed those who used her heart, slaughtered everyone in the hospital, become its boss, and perhaps even turn into an S-class monster.

But something did go wrong.

Professor Yang, who had used Gao Siyun's heart, had already become half a monster. He took revenge on the spot, killed all his enemies, and took his daughter away.

Gao Siyun, who ultimately failed to save her child, finally transformed into something truly terrifying.

This family wasn't inherently bad. If anything, they might even be considered noble people. Everything Gao Siyun did in the beginning came from love.

But love seemed out of place in a world filled with malice, and in the end, it gave birth to the most terrifying monster of all.

Is "love" the most powerful force?

Mo Bai put the report away and asked Du Heng, "Can you tell me more about the Four Pillars of Heaven?"

Du Heng replied, "I don't know much either. I only heard the captain mention it. He said that Ultra-Star Rank monsters who become part of the Four Pillars of Heaven are fundamentally different from the S, A, B, and C-class monsters we encounter in instances.

The most important difference is that ordinary instance monsters just want to stay in their own domains, guard their territory, and live their twisted but comfortable little lives.

But the Four Pillars of Heaven yearn for light and a warm world. They break out of their domains and head into ours."

Mo Bai thought of what had happened to that family. If she were Gao Siyun, she wouldn't want her daughter to continue living in such a world. She would hope that her revived daughter could go somewhere more normal.

As for this world, it wouldn't matter if it were destroyed.

She recalled that most of the test subjects in Biological Research Institute No. 7 had been residents of this town. According to them, more and more people in the town had been developing terminal illnesses in the past few years, which was why they had signed life-and-death contracts to become experimental subjects.

If Gao Siyun had never left the town, then perhaps the surge of illness over the years had been her doing.

She was constantly creating test subjects for the institute.

The little girl had been taken away by Professor Yang, but no one knew where she was hidden.

After leaving the town, Professor Yang himself developed a split personality, and whether the fragmented version of him still remembered his daughter was unclear.

At least the Professor Yang Mo Bai encountered was selfish and cold, no longer a loving father, but someone obsessed with becoming a "complete being."

Still, his research might have helped revive his daughter. Perhaps once he became complete, he could have used the power of an Ultra-Star Rank monster to bring her back.

But Mo Bai and her group interrupted his plan. They killed him.

The large-scale mutation of Disease Town began after the destruction of Biological Research Institute No. 7. Perhaps Professor Yang's death made Gao Siyun realize that waiting for him was meaningless. Seven years have passed, and it was all for naught. So she took matters into her own hands.

She gathered the research findings of the institute, preparing to sacrifice the entire town to heal her daughter.

In this instance, it was unclear whether Gao Siyun or the little girl would ultimately become the Ultra-Star Rank monster.

Either way, if they wanted to win, they had to eliminate Gao Siyun first.

Her resentment was too strong. Mo Bai, who absorbed Ultra-Star Rank monster genes and suffered a backlash, was one thing. But Du Heng, Sheng Yan, and Liu Congyi had only injected the extract, and yet they were already in such a miserable state.

Gao Siyun was no longer the gentle mother she once was.

Now, she would kill everyone.

Having pieced together most of the truth, Mo Bai looked at her three teammates, some crippled, some unconscious, and prepared to deal with their injuries.

Liu Congyi's situation was the easiest to handle. It didn't matter if her hearing didn't recover for now. The negative impact wasn't significant.

Her real problem was mental contamination. Once she woke up, she would need to use the Memory Erasure card to treat herself. But in her current mental state, she clearly wouldn't be able to do that on her own. They would need some kind of manipulation-type ability to make it happen.

Ding Xun's Synesthesia ability could do exactly that.

They could have Ding Xun use Synesthesia to temporarily take control of Liu Congyi's five senses and order her to take out the card.

Until they found Ding Xun, though, it was better to keep Liu Congyi unconscious. Just leave her like this.

As for Du Heng and Sheng Yan, Mo Bai had a solution.

She had a Tentacle Substitute card, and Gu Tiandong had a Blessing of the Puppets card. Together, those two cards could save two people.

But for now, she was separated from Gu Tiandong and the others. She only had the Tentacle Substitute card on hand and couldn't decide who to save first.

Mo Bai placed the card in front of the two men and let them choose.

Sheng Yan spoke without hesitation. "Give it to Du Heng. My abilities are sealed by this town. Saving me won't help."

Du Heng didn't argue. He picked up the card and said, "Sheng Yan, I owe you one. Once I find our teammate from Mending Heaven, I'll ask her to save you.

Mo Bai, you've saved my life again. There's no point in thanking you. The bond between us is way past that. Just know this: my life is yours. Unless I'm dead, no one can hurt you!"

With that, Du Heng used the card.

It turned into a gray light that wrapped around him, attaching to his paralyzed legs and transforming into two limp tentacles.

The tentacles flopped onto the ground and disappeared as Du Heng stood up.

Not only did he recover his health, but even his completely depleted energy had been restored by the card.

Delighted, Du Heng bounced around a couple of times, then started darting back and forth beside Mo Bai like an overexcited monkey, saying, "Mo Bai, if we team up, I might even be able to take down that Avici Calamity player.

We'll get close to him. You use Environmental Rejection to block his ability. Then I get inside your protective range and use Soul Reaping at close distance.

Even if he's an Advanced player and can't be killed in one hit, I can just reap him a few more times. Three should be enough to finish him."

Before Mo Bai could speak, Sheng Yan, gritting through the pain, questioned him:

"Why is your first thought after recovering your strength not to go after the monsters, but to take out the Avici player?

I get it, we have a grudge. Last time, someone from Avici even worked with Professor Yang in the instance. But this time it's a different person, and he's actively clearing monsters. He doesn't seem like he'll team up with them again. In that case, shouldn't we set our grudges aside for now and try to work together against the monsters?"

"Uh…" Du Heng opened his mouth but couldn't come up with a reason.

Mo Bai understood. In Du Heng's mind, with the Observation Group in play, players from Avici were actually more dangerous than the monsters.

She stepped in to smooth things over, teasing Sheng Yan, "I really can't believe those words just came out of your mouth, that you've actually learned to set aside a grudge and team up with the other side. You've grown, Sheng Yan."

Sheng Yan flushed slightly, embarrassed. "It's mostly because I can't help. We're lacking strong combat power, so teaming up would be more beneficial."

"But some people aren't suitable allies," Mo Bai said.

She remembered what Du Heng had said earlier and asked, "Can your other teammate from Mending Heaven save him?"

Du Heng glanced at her. "My teammate is an Observation Group player. A very rare Observation Group player in Neverland. Her ability can heal Sheng Yan's injuries, and also temporarily seal his power to prevent him from being harmed by the rules again."

"Healing-type players are rare?" Sheng Yan asked, slow to realize how uncommon Observation Group players were in Neverland.

"It's more than just healing. You'll understand when you meet her," Du Heng said. "Because this instance is called Disease Town, the captain sent her here, and I was supposed to protect her. We got separated as soon as we entered, and then I ended up useless. Now I don't even know where she is. I just hope she doesn't run into players from the other two organizations."

"From the way you're talking, it sounds like players are more dangerous than the instance monsters," Sheng Yan said, puzzled.

Mo Bai just smiled without answering.

Du Heng scratched his head and awkwardly changed the subject. "She shouldn't be discovered. Her concealment ability is extremely strong. Very few people can detect her. So, Mo Bai, what do we do next?"

After rescuing Du Heng and the others, Mo Bai still needed to find Gu Tiandong and the other two. Since they weren't in the Abandoned Hospital, she would have to search instance by instance.

For now, though, they couldn't leave the hospital. The danger inside hadn't been resolved yet.

And there was no telling what happened on the inpatient side. Who won the battle between Li Ming and the nightmare creature?

Mo Bai's Prying Lenses could only be used one more time. After that, it would disappear. If Liu Congyi could wake up now, she could help restore the card and replenish its uses, allowing it to be used three more times before it vanishes.

But Mo Bai didn't dare wake her.

"Then just bring an extra pair of glasses," Sheng Yan suggested.

As the three of them were at a loss, the Dismemberment Forensic Doctor said quietly, "There's surveillance in the outpatient building's basement level."

He stood beside Mo Bai, calm and obedient, as if he had been completely subdued. He even took the initiative to offer help.

Du Heng pointed at the completely collapsed underground passage. "After that electric shock, are you sure that the hospital's surveillance equipment still works?"

The Dismemberment Forensic Doctor replied, "The hospital's surveillance isn't used to monitor the building itself. It monitors the nightmare creature's dreams. It doesn't need a power source. And as long as the nightmare creature isn't dead, the system won't be destroyed."

"Why monitor his dreams?" Mo Bai asked. "Isn't it because you're afraid people will see them?"

"The footage doesn't show the actual contents of his dreams," the Dismemberment Forensic Doctor explained. "It only shows who enters the range of his dream. It's to prevent anyone who enters his dream from finding the secret room hidden inside it. If someone does discover that room, I'm supposed to use the surveillance to wake the nightmare creature and have him personally destroy that person's mind."

"There are more secrets in that room?" Mo Bai asked.

The Dismemberment Forensic Doctor shook his head. "I don't know. I don't remember. I'm just following the rules."

"Alright. Let's check the surveillance room," Mo Bai said.

"This way is impassable," Du Heng said, carrying Liu Congyi over one shoulder while supporting Sheng Yan with the other, staring at the completely blocked rubble in front of them.

Mo Bai stepped forward, picked up a chunk of broken concrete, and placed her other hand against the wall.

Countless transparent threads extended from the ends of her hair, linking to every piece of steel and concrete.

Almost in an instant, the debris broke apart, and a fairly wide path opened before them.

Mo Bai withdrew her hand and swayed slightly.

Her energy was completely depleted.

The Ultra-Star Rank monster energy she had drawn from inside herself had been drained by the little girl. Now, she could only rely on her own energy to activate Environmental Rejection and Environmental Assimilation.

Using high-level energy twice in a row had emptied her reserves and even overdrawn her Mental Power.

Mo Bai took out her intermediate nutrient potion but didn't drink it. She just kept it on hand for later.

She only had one bottle, so it needed to be saved for a critical moment. For now, she would let her body recover naturally.

Sheng Yan noticed her condition and tossed his own nutrient potion to her. "Take mine. My abilities are basically useless in this instance anyway."

"Thanks," Mo Bai said.

On the other hand, Du Heng stared at the path that had been cleared in an instant, both amazed and delighted. "Mo Bai, your ability has gotten this strong? Are you already at the Advanced level?"

At the mention of "Advanced," a trace of concern flickered in his eyes.

"Not yet," Mo Bai reassured him.

With the Dismemberment Forensic Doctor leading the way, they followed him and quickly arrived at a room.
