"Don't act so smug," Rabbit said to the puppet. "But… you're right, I won't let this traveler kill you." It turned its head back to Feng Bujue and said, "You, go and catch him for me first."

"Catch 'him' for you?" Feng Bujue glanced at the puppet and repeated, "Him?"

Rabbit replied, "At the forty-first minute, I already gave you the potion I possessed. It was also at that time that you caught him." It pointed to the fourth corridor. "You came from there at that time."

[Current Quest Changed, Main Quest Updated]

The system prompt sounded at this moment. Feng Bujue opened the game menu and saw that a task had been added to the sub-menu of the original [Find the Chemical Potion (04)] task: [Find and capture the puppet Billy in the fourth corridor and bring it to Rabbit in exchange for a bottle of chemical potion.]

Feng Bujue raised his head and took a deep breath. "I have a hypothesis. If I go back now, catch him, and hand him over to you at the forty-first minute, and then I don't take the potion," he paused for a second, "then, will the current situation change?"

Rabbit said, "You mean, if you did that, the potion in my hand should still be there, right?"

"Yes," Feng Bujue said.

"But, you already took it." Rabbit looked into Feng Bujue's eyes. "Can you understand?"

Feng Bujue was stunned for a few seconds. "You mean…"

"Because you took it at that moment, that's why you're asking me this question at this moment," Rabbit replied. "According to another possibility… assuming you didn't take it then, then I would give the potion to you at this moment, but even so, you still have to catch Billy, because if you don't catch him, my cell at this moment will be empty, and I won't give you the potion. This is a paradox."

"And if you catch him as usual and return to the forty-first minute, there are two possibilities. The first is that you take my medicine, then the previous you’s actions and existence will be denied," Rabbit said, "And if you don't take it…"

Feng Bujue continued, "The me who is discussing this issue with you will also be denied."

Rabbit raised its hand, "Think about it, if you choose the wrong path, causing a space-time paradox to occur…"

"The game will fail directly…" Feng Bujue pondered. He turned his head and looked at the puppet. "I really want to talk about life with you."

"Hehe…" The puppet Billy chuckled in a deep voice, "And how do you know we haven't talked about it?"

Feng Bujue paced back and forth in front of the four corridors. "Was I the one who brought him back from the fourth corridor…" he asked again, "Besides the potion in your hand, where are the other three?"

Rabbit replied, "The one in my hand is actually Alden's." It waved its hand and winked at Alden. The latter disappeared instantly. Rabbit continued, "He is the more cooperative one of the four."

"Four people?" Feng Bujue's gaze shifted to the four cells.

Rabbit knew what Feng Bujue wanted to ask. It replied directly, "There should have been four prisoners in these cells. The former warden here, Samodier… I think you should have heard of him. He thought he was also a prisoner, so one day, he opened four doors, released these prisoners, and defected." It sat back in the chair and turned off the lights in Billy's cell. When the lights went out, the puppet seemed to have entered another space, completely isolated from this place.

"So, the master sent me to take over here." Rabbit continued, "Alden is more cooperative. He just likes to stay in dark and confined places and occasionally listen to a few ghost stories. He didn't show any aggression or resistance. I regard him as a model prisoner, so I made him my assistant."

"A traitor…" Feng Bujue said.

"What did you say!"

"Never mind," Feng Bujue smiled and glossed over it.

Rabbit snorted and continued, "There is a potion in each corridor you are looking for. The one in the third corridor where Alden is located has already been given to me by him, and I have already given it to the 'you' of 'not long after' in the 'past'." It paused, stroking its beard, seeming to think it was a bit convoluted, "The puppet Billy was hiding in the fourth corridor before. There is also a potion in his place, and you who caught him have naturally already obtained that potion."

"Okay, I understand." Feng Bujue said, "That is to say, currently, there is a potion in each of the first, second, and fourth corridors, and another potion was obtained after I entered from the beginning of the fourth corridor, caught Billy, and sent him here."

Rabbit nodded to confirm.

"The last two questions. First, purely in terms of distance, which corridor is the shortest?" Feng Bujue wanted to find the shortest corridor and run back to the beginning first, because it was already around eighty-four minutes. He was worried that the time difference would not be enough for him to deal with the small boss in the first or second corridor, and then return to the beginning.

He planned to go back first, and then enter the fourth corridor from the beginning, so that the map time would rewind, so that he would have time to stop and do something while passing through the corridor.

"I don't know." Rabbit replied, "I've only been to the first corridor, and I haven't been to the others, so I can't compare which one is longer and which one is shorter."

"What? How are you a jailer?" Feng Bujue asked.

"If I could come and go freely, I would have caught the prisoners myself. Do I still need you to do it for me?" Rabbit replied confidently.

"What about the guy hiding in the first corridor? Has he been caught by you?" Feng Bujue raised his head and looked at the four dark cells behind Rabbit. "Which one is he locked in? Where is the potion on him?"

"I just said… I've been to the first corridor, but I didn't say I caught him." Rabbit replied, "That guy… is quite special. I personally suggest you go to that corridor last."

"Damn it!" Feng Bujue complained and turned to leave.

"Hey! Didn't you have two questions? What's the second one?" Rabbit asked.

Feng Bujue ran towards the second corridor, shouting back without turning his head, "The second question is… why don't you catch them all yourself!" His figure quickly disappeared into the corridor.

At this moment, the time experienced by Feng Bujue personally, according to his mental calculation, was approaching forty minutes.
