**【09:21】**
The train had been running for twenty-one minutes.
Twenty-one minutes since the dungeon loaded. Twenty-one minutes since the rules dropped. Twenty-one minutes of the rules shifting silently while over a thousand people in seven carriages cycled through panic, exhaustion, and brief moments of false calm.
Liam Cross had been in the last carriage for almost ten minutes, studying the dead man's phone interface.
Not just the red text. Every menu. Every subpage. Every faint little UI element that the system might have hidden.
He discovered a few things:
First, the dead man was a late arrival. His log-in time showed 09:02. So he had broken the hidden rule **and** he was a late arrival. Two violations stacked.
Second, the dead man's survival points had dropped to zero in a single violation. That meant the penalty for breaking hidden rules was much heavier than the penalty for breaking public rules.
Third—and most importantly—the dungeon interface had a subpage that was only visible to "blacklisted" accounts. And on that subpage, one sentence:
**【——Number of late arrivals currently in the dungeon: 527.**】
527.
Out of 1,284 total participants. That's how many people were still marked as late. In other words, the death just now—hadn't scared anyone. People were still sharing information, still talking to late arrivals, still unaware of the hidden knives in the fine print.
Simon Xu leaned in and whispered: **"527 late arrivals. If they all find out the rules and we're sharing this carriage with them..."**
Liam Cross didn't answer. Because he was thinking the same thing—if a hidden rule had already killed one person, how many more would die before they figured it out?
And more importantly, what would happen when 527 late arrivals discovered that the rules had been stacked against them from the start?

The answer came three minutes later.
**【09:24】**
A scream from the middle carriage.
Then another. Then layers of overlapping screams.
Simon Xu instinctively took a step back. **"What now? Another death?"**
Liam Cross stood up and walked toward the source of the noise. Crossed one carriage. Crossed half of the second. Then stopped.
He saw the second body.
A woman. Thirty or so. Dark blue windbreaker. Lying face-up in the middle of the aisle, eyes wide open, lips slightly parted, as if she'd tried to say something before she died but the words never made it out.
Her phone was on the ground next to her. Screen on. Displaying the same red text as the first body.
**【Participant eliminated. Cause: Rule violation. Specific content: Blacklisted.**】
And the same supplementary hidden rule.
**【——Hidden Rule 1: On-time participants are prohibited from sharing dungeon information with late arrivals before the first stop... Currently violated by 2 people.**】**
Two. Up from one.
Liam Cross crouched beside the body and looked at her phone more carefully. This woman had also shared information with late arrivals. But the time was different—she'd done it at 09:23, twenty-three minutes into the dungeon. Which meant the **"before the first stop"** condition hadn't been met yet. The first stop hadn't happened. So anytime before the first stop counted.
He turned to the crowd of stunned onlookers. **"Who did she talk to?"**
Silence.
**"Who did she tell the rules to?"**
A young man in a gray hoodie slowly raised his hand. His voice was trembling: **"She... she told me. I got on at 09:01. She said I was a late arrival and told me the rules because she felt sorry for me. She said it was unfair..."**
Liam Cross stood up. **"Don't repeat what she told you to anyone else. And don't tell anyone else the rules."**
The young man nodded rapidly, his face pale.
Simon Xu whispered from behind: **"So the hidden rule... it really kills anyone who shares info with late arrivals?"**
**"Before the first stop."** Liam Cross corrected. **"Before the first stop, you can't share. After the first stop, it might be different."**
He looked at the woman's face. Her eyes still open.
**"She just wanted to help someone. And the system killed her for it."**

**【09:28】**
Liam Cross went back to his spot near the door and sat down.
He wasn't just sitting. He was watching.
Watching the crowd. watching the interactions. Watching who was talking to whom, who was staying quiet, who was trying to take charge.
There were already people trying to "lead."
A man in his forties, wearing a brand-name suit and carrying a leather briefcase, had positioned himself in the center of the middle carriage and was addressing the crowd in a loud, authoritative voice. **"Everyone, stay calm! I'm a senior manager at a multinational corporation. I've handled crisis situations before. We need to organize—"**
Some people gathered around him, drawn to the confidence. Others stayed where they were, watching skeptically.
Simon Xu came up beside Liam Cross. **"That guy's taking charge. Should we join them?"**
**"No."**
**"Why not?"**
Liam Cross looked at the man's phone. Still in his hand. Still on the dungeon interface. And the man's face—Liam Cross could read a micro-expression that others might miss. Beneath the confident facade, there was flickering uncertainty. Like someone reading lines from a script they'd just memorized.
**"He's not a leader. He's an opportunist. He saw a power vacuum and filled it. But he doesn't know the rules any better than anyone else."**
Simon Xu frowned. **"So what do we do?"**
Liam Cross leaned back against the seat. **"Wait."**
**"Wait for what?"**
**"For the first stop."** Liam's gaze was steady. **"The first stop is the key. Before the first stop, hidden rules are active. After the first stop, the system says the train will open for on-time participants to get off. That's when the rules change."**
He paused.
**"And when the rules change, that's when people like him—"** he nodded toward the self-proclaimed manager **"—start making mistakes."**
Simon Xu looked at the man in the suit, then back at Liam Cross. He didn't say anything, but there was a new look in his eyes. Not helplessness. Something more like... focus.

**【09:32】**
The train's speed began to drop.
Not suddenly. Gradually. The rumbling of the wheels against the tracks changed pitch, and the lights flickered once before stabilizing.
Everyone felt it. The carriage went quiet all at once.
The man in the suit stopped mid-sentence, his hand frozen in mid-gesture. People held their breath, waiting, watching.
Liam Cross stood up. Walked to the door. Looked out the window.
The tunnel was thinning. He could see lights ahead—not the dim tunnel lights, but broader, brighter lights. A station.
**【09:33】**
The train pulled into a platform.
But it wasn't any station Liam Cross recognized. The station sign was blank. No name. No route map. No ads. Just a bare platform with cold white fluorescent lights, empty, stretching in both directions as far as the eye could see.
The train stopped. The doors didn't open.
Then a broadcast sounded. Not through the train's speakers. Through every participant's phone. A clear, synthesized voice, gender-neutral, without emotion:
**【First stop reached. All on-time participants—please disembark. Late arrivals—please remain seated. Those who have shared dungeon information with late arrivals before this stop are in violation. Action will be taken.】**
The doors slid open.
For a long moment, nobody moved.
Then Liam Cross stepped forward, crossed the threshold, and stood on the platform.
Behind him, the carriage remained frozen in a tableau of fear and confusion.
