The college students had kicked until their feet hurt, but the door remained firmly shut.  

Finally, their hope arrived—Xiao Peng.  

Xiao Peng hadn't gone with them to Room 504 initially, instead going to find the apartment manager Xiao Zhang for the spare key.  

Seeing Xiao Peng arrive, the tall male student's eyes filled with hope.  

But Xiao Peng looked awkward: "No key. Even Xiao Zhang doesn't have a spare for this apartment."  

"What do we do then?" a female student asked urgently.  

"We'll have to wait for the police," Xiao Peng said.  

The tall male student objected: "We can't wait! Every second increases the danger! Especially since we've already alerted them!"  

Xiao Peng shrugged helplessly: "Then what can we do?"  

Just as the group stood frozen in panic, a sixty-something old man in a brown suit emerged from neighboring Room 503.  

The elderly gentleman dressed fashionably, his hair meticulously styled.  

He carried himself completely differently from typical old men.  

The suited old man asked sternly: "What are you doing? I could hear you pounding on the door from next door."  

The tall male student pointed at Room 504's door: "Sir, my friend is inside 504!"  

The old man frowned: "Your friend? Then have your friend open the door. Why are you breaking it down?"  

The tall student urgently explained: "She must be trapped inside! She wouldn't answer if she could! Something's wrong! Sir, do you know who lives in 504?"  

The old man stroked his chin thoughtfully: "I'm not familiar with the resident, but I've seen him a few times—shifty-eyed fellow who looks dishonest. Wait, your friend isn't this person?"  

"My friend was just visiting 504! She doesn't live there!" The tall student grew increasingly frantic.  

Xiao Peng and Xiao Nuo nodded in anxious agreement.  

The old man seemed to reach a decision after some internal debate.  

"Fine, this old man will help you youngsters out!"  

"Help us? How? Can you pick locks, sir?"  

Under the group's watchful eyes, the old man returned to his apartment briefly before reappearing—carrying a massive electric saw.  

The stunned students gaped as the old man confidently pulled the saw's starter cord and approached Room 504's door.  

Turning back, he solemnly confirmed: "Kids, you're absolutely certain your friend is in there? In trouble?"  

The tall student practically shouted: "YES! Please hurry, sir! I'll take full responsibility!"  

Nodding, the old man declared: "Right then, stand back."  

With practiced motions, the suited elder began sawing through the door.  

The sturdy door that had resisted their kicks now yielded like soft tofu under the roaring saw's teeth.  

The moment an opening appeared, the group surged inside.  

In the living room stood a neatly dressed middle-aged man, furious: "What's the meaning of this? Breaking into my home?!"  

Ignoring him, the students frantically searched for Wang Ju.  

Xiao Hua pointed at the bedroom door: "This one's locked!"  

"OPEN IT NOW!!!" the tall student bellowed at the man.  

The man shouted back: "This is illegal entry! I'll sue you all!!!"  

Having come this far, the tall student grabbed the saw from the old man and cut through the bedroom door.  

They knew Wang Ju was inside even before fully breaching—shadowy movements visible through the growing gap.  

When they finally burst in, the first students froze in horror.  

Wang Ju's neck gushed blood like a crimson fountain.  

The scarlet tide had soaked her neck, face, torso, bedding, and dripped onto the floor.  

The tall student couldn't process the nightmare—especially since Wang Ju still clung to life.  

Despite the gaping neck wound, her mouth moved weakly—likely pleading for help—each motion spurting more blood.  

As more students crowded in, they witnessed Wang Ju's brutalized naked body tied spread-eagle on the bed, clearly violated.  

"All boys OUT!" the female students ordered through tears, pushing the males into the hallway.  

Dazed momentarily, the tall student's shock transformed into crimson rage.  

Spotting the middle-aged man—Lin Shengli—trying to escape, he lunged.  

"I'LL KILL YOU, YOU ANIMAL!!!"  

His massive frame fueled by witnessing his beloved's torture, the tall student lost all restraint.  

Lin Shengli initially resisted but soon collapsed under the blows, laughing shrilly through broken teeth:  

"Hahaha! I planned to enjoy her properly at 7pm! You ruined my schedule so I had to rush!!"  

"YOU FUCKING BASTARD!" The tall student's fists became blurs: "You monster! Why kill her after... after...?!"  

Bloodied and missing an eye, Lin Shengli cackled: "That's my signature! First the fun, then the finale! Hahahaha!!"  

"I'LL MURDER YOU!!!"  

Snatching up the still-running electric saw, the tall student raised it overhead.  

Xiao Peng—mid-120-call—yelled for others to stop him, but none dared approach the frenzied giant wielding the buzzing death tool.  

"Go on! Kill me!" Lin Shengli taunted as the saw hovered over his chest. "You'll just join me in hell!"  

Miraculously, the tall student hesitated—the legal consequences piercing his rage.  

But Lin Shengli, with grotesque smirk, delivered the final provocation:  

"Ah... though plain-faced, that Wang Ju had such smooth young skin... exquisite texture when I touched her everywhere..."  

The saw descended.  

Flesh parted. Blood geysered. Bones crunched.  

Screams filled the apartment until they didn't.
