Soon after "Bai Liu" got off the bus, Bai Liu's body materialized from a translucent data virtual state. He pinched his palms thoughtfully, and he could touch the passengers around him.

It is not known whether his existence became virtual because the two "Bai Liu" were in the same time and space, or whether his body became virtual because "Bai Liu" was about to die if he did not get off the car, but none of this matters anymore.

The next stop is the Antique City. He is still on the train, and the train will explode in three minutes at most.

"Bai Liu--!!" Mu Sicheng's voice came from another crowded carriage. He squeezed to the side of Bai Liu with great difficulty, his face was extremely ugly, "There are so many people here, how can we find the broken mirror?! We are about to arrive at the station! This last train will explode before it arrives!"

"And I just tried it. I wanted to get off at that station." Mu Sicheng said solemnly, "But I couldn't get off. It was like something was blocking me on this train."

But Bai Liu turned a deaf ear to Mu Sicheng's anxious nagging. Instead of closing the conversation, Bai Liu said to him, "This is the reality. Because the real you is not on this train, you cannot get off. The real me has just gotten off, so I cannot get off again on a train that I have already gotten off. The causal relationship will not hold and the logic of the game will be disrupted."

"What reality?!" Mu Sicheng asked in alarm, "Bai Liu, this is not reality, this is in the game! Is your mental state not low? Are you hallucinating? What nonsense are you talking about whether you should get off the bus or not?"

"That's not what I meant." Bai Liu tapped Mu Sicheng's shoulder with his finger, then pointed to the subway map on the carriage, "Look at this map. The previous stop after the Antique City is Lujiazui, not the reservoir. Pay attention, this subway line is not a loop, it's a linear subway line. This is the subway map in our real world."

Mu Sicheng followed Bai Liu's hand and noticed this. He frowned, "But we can't go back to reality. We are in the game."

Bai Liu seemed to have realized something and continued, "When I say this is 'reality', I don't mean that we have returned to the real reality. The 'reality' here is relative to the train full of charred corpses that we were in before. That place is not the real game world. That place is just a mirror world that keeps looping."

"And the train we are standing on now." Bai Liu tapped his feet with his toes, his eyes calm, "is the real reality relative to the game, or it can be said to be a parallel time and space caused by the possibility derived from the reality that has already happened. The prototype of this game is the [Mirror City Bombing Case]. Generally, the reference prototype of our games is to highly restore the events in the game, which is already very good. But this game has a greater ability than restoring events."

"It recreates the scene of the incident." Bai Liu looked at Mu Sicheng, "It takes us back to the time of the explosion, and then at this point we players control it. It will calculate the possible scenes based on our control, leading to different consequences."

For example, when Bai Liu boarded the train just now, his first reaction was to look for himself and Lu Yizhang. Originally, Bai Liu did not sleep on this train because it was cold, but Bai Liu who boarded the train brought something with him, which made the carriage warm - 380 broken mirror fragments that had just exploded. When Bai Liu entered the mirror world, these 380 broken mirror fragments automatically entered his system backpack.

Bai Liu is virtual, but the mirror is real. Bai Liu's approach allowed the remaining heat on the mirror to warm the tired "Bai Liu", causing him to really fall asleep, and prevented him from getting off the bus with Lu Yizhan as Bai Liu remembered.

But Mu Sicheng didn't care about these at all. He just needed to know that Bai Liu knew that they were still in the game. With the train about to explode in three minutes, Mu Sicheng was extremely anxious. He was focused on passing the level and grasped the key information from Bai Liu's words.

"The mirror world that keeps looping?" Mu Sicheng asked anxiously, "What does it mean to keep looping?"

"Don't you think there's a big logical flaw in our previous mission to collect mirror fragments?" Bai Liu said lazily, "We were supposed to collect mirror fragments from the last train that was about to explode, right?"

Mu Sicheng nodded: "Yes."

"But..." Bai Liu raised his eyelids and looked at Mu Sicheng with a half-smile, "If this last train has not exploded, where did all the broken mirrors on the train come from?"

"Unless it has exploded, we will have fragments of mirrors left over from the explosion to collect."

Mu Sicheng was completely stunned for a second or two before he came back to his senses. He muttered to himself in a trance, "This is the last train that keeps looping, exploding again and again... It's useless for us to collect the broken mirrors in there. After collecting them, we will probably be completely trapped on the last train that keeps exploding. So those passengers are trying to stop us. Damn - they are saving us stupid players."

"Yes, I noticed before I got to the subway station that the direction of the elevator in the subway station was reversed, and the order of passengers getting on and off was also reversed. Even our mission was, to some extent, reversed." Bai Liu explained clearly, "Our mission was to collect the broken mirror fragments, but in fact, the broken mirror fragments had already been collected by the [passengers]. What we did was to scatter these collected broken mirror fragments again, and it seemed that we were doing the work of the villains, and those passengers were right. I guess this is one of the characteristics of the mirror - [reversing the properties of the object itself]."

"So I think the main quest in the mirror is the opposite of the real quest in the real world we are in." Bai Liu's eyes were calm and lazy, and his hand was picking up the coin in front of his chest from time to time. "In the reality we are in, the train has not exploded, which means that the mirror has not been broken at all. The quest in the mirror is to collect and piece together the mirrors, so the other way around is-"

Mu Sicheng suddenly realized something: "We have to break the mirror!"

Bai Liu smiled and snapped his fingers: "Bingo."

[System prompt: Congratulations to players Bai Liu and Mu Sicheng for triggering the ultimate main quest - smashing the evil ghost mirror and ending the endless cycle of explosions in the mirror]

[System prompt: The 380 mirror fragments on Bai Liu have been returned to their original positions. Players are requested to quickly find the real mirror and break it to pass the level]

Mu Sicheng heaved a sigh of relief, looking at Bai Liu. He couldn't help but sigh, "You guys, even in this situation, your mind is still clear?"

Three minutes of explosion countdown, one health point, this guy is still in the mood to think about the real mission in the real world, isn't he anxious? !

"But where is the mirror?" Bai Liu was not anxious, but Mu Sicheng was. "This train has 6 carriages in total. There are only two minutes left. It is impossible for us to search every carriage."

"No need to look." Bai Liu leaned against the door slowly and pointed, "I've taken this train before. Before I got off, I remembered that the thieves were in this section, so I came directly over. As expected, they were in this section, standing in the middle."

Mu Sicheng looked over and saw two passengers, one big and one small, standing in the crowd. They were pushing a huge suitcase, which was just big enough to fit a mirror. The mirror should be inside. There were also a few men in suits standing next to them. They should be the museum staff. Mu Sicheng immediately realized that they were the thief brothers. He glanced at Bai Liu and was a little speechless: "You saw it a long time ago, why didn't you go over? Why are you standing here without moving?"

Bai Liu smiled and said, "Isn't this just waiting for you to steal the mirror, big thief? How can I have the ability to steal things from another pair of thieves? Of course you have to come here to do this."

Mu Sicheng was startled, then he slowly curled his lips and sneered, "You are good at saving trouble."

After he finished speaking, Mu Sicheng's eyes changed, becoming cold and concentrated. He adjusted the position of his headphones, put on the hood and pulled it down to cover his eyes. He swung his right hand diagonally backwards, turning it into a sharp, clasped monkey's paw, and his figure swayed past the passengers around him like a ghost.

Before Bai Liu could see what Mu Sicheng did, he heard the thief brothers screaming, "The mirror is gone! There's a thief!"

The crowd in the carriage suddenly became agitated. Bai Liu turned around and felt someone grabbing her collar. Mu Sicheng, who was wearing a hood, was holding the box in one hand and Bai Liu in the other. He ran at full speed on the wall of the carriage with a wanton smile on his face. Behind him, the thief brothers were shouting at the top of their lungs: "Catch that thief!!!"

Mu Sicheng showed the knife expressionlessly and said the word "get out". The crowd immediately screamed and made way in panic, running to other carriages. Mu Sicheng ran all the way to the rear carriage and scared away the other passengers in the carriage, leaving an entire carriage free for them.

"Cool, Mu Sicheng, you're really good at doing bad things." Looking at the carriage that was suddenly empty, Bai Liu praised sincerely.

Mu Sicheng raised his eyebrows: "Same here."

Bai Liu squatted down and opened the box. Sure enough, there was the mirror inside, and it was intact. The moment Bai Liu stood up the mirror, he heard the system's harsh warning.

[System warning: When the mirror is broken, the god-level NPC will break out of the mirror, and all players in front of the mirror will be attacked indiscriminately. Players, please be careful to break the mirror! ]

Being attacked by the god-level NPC, both Bai Liu and Mu Sicheng would surely die with their current health points. The smile on Mu Sicheng's lips quickly disappeared, and the only sounds in the empty carriage were the sound of the wind blowing in when the train was running, and the small sobs of a passenger who was scared to tears by Mu Sicheng coming from another carriage.

A sweet female radio voice sounded at the right moment:

"We are about to arrive at the final stop——"
