After leaving the restroom, Lu Yuan even considered changing his plans.
But considering how many guards were stationed here, and how many people were above, Lu Yuan had no choice but to bite the bullet and go.
He dared not recall what had just happened; the thought of it made him feel nauseous.
So, Lu Yuan returned to the crowd.
Sun Ping was sweating profusely from his work, but seeing Lu Yuan already seated in the crowd made him feel much more at ease.
"How's things going?"
Sun Ping nodded: "I've already notified them! I'll cover for you!"
"Okay! That's good! Get everything ready here, and wait for my news! By the way! Is there any way to get up there?"
Sun Ping was stunned: "Go up? You're planning to go to the next hostage area?"
"Yes! I can't possibly rescue you layer by layer, can I? If we're going to leave, we have to leave together! Otherwise, these guards aren't stupid. Once they find out I've taken you away, they'll definitely strengthen their defenses!"
"Alright! I don't know where I can get up here either! The defenses here are..."
Just then, the mischievous Qiao Nana popped up again: "I know! I know there's a way up!"
Lu Yuan couldn't help but look at the other person with curiosity: "How come it feels like you know everything?"
Qiao Nana chuckled and said, "Because I used to be a parkour enthusiast! I need to understand these tall buildings! Although my parents don't let me take risks, I've done my homework quite thoroughly!"
"Alright! Then tell me!"
Then Qiao Nana looked at the nearby guards: "There's a ventilation shaft that leads all the way to the top floor! Very few people know about this place! It was originally kept as a backup, but it was later shut down, and nobody knows why!"
Upon hearing Qiao Nana's words, Lu Yuan immediately understood why the ventilation shaft had been sealed off in the first place. At that time, the zombie virus was spreading in the urban area, so they had no choice but to shut down all the fresh air systems.
However, it was later proven that the zombie virus does not spread through the air, and the conditions for its spread are quite demanding. Not everyone is affected, and the matter was eventually dropped. These ventilation shafts were never opened again.
"Haha! I almost forgot about that! Haha! I didn't expect you to be such a walking encyclopedia!"
After being praised by Lu Yuan, Qiao Nana showed a satisfied look on her face.
"Of course! I know a lot more!"
"Okay! That's good! Take me there!"
Just as Qiao Nana was about to take Lu Yuan over, Lu Yuan grabbed her arm.
"Wait a minute, I want to ask about that ventilation shaft..."
"Haha! Don't worry! That ventilation shaft won't be placed in the toilet! Unless these people want to smell fresh feces every day!"
"Ugh! Stop talking! I'm about to throw up! I'll leave you something later! Then we'll carry out the mission at the time we agreed!"
After saying that, Lu Yuan looked at Sun Ping: "Now let's check the time!"
Sun Ping nodded: "Okay!"
After checking the time, Lu Yuan looked at Sun Ping and said, "There are still forty floors to go, and I have to communicate with each floor, which will waste a lot of time. So, let's set the time later! It's already nine o'clock in the morning! Let's set the operation for nine o'clock tonight! Any problems?"
"Okay! So all we need to do is light the fuel?"
"That's right!"
After saying that, Lu Yuan pulled a long flamethrower out of his pocket as if by magic and carefully handed it to the other party.
"Put it in a safe place! You might need it later! Remember! Don't let it show! Otherwise, I won't be able to save you!"
Upon hearing this, Sun Ping nodded repeatedly, his serious expression making Lu Yuan feel somewhat distrustful of him.
Before leaving, Lu Yuan specifically sought out Qiao Nana: "That Manager Sun seems a bit dull, so please remind him a bit!"
"Okay, Brother Lu, then... will you come back to save us?"
Lu Yuan nodded: "Of course! Otherwise, why would I have come all this way? Alright! Take good care of yourself! Take me there first!"
So Qiao Nana led Lu Yuan to a slightly open space. The awkward thing was that this was where the guards rested; they would come here to rest when they got tired of standing. So Qiao Nana looked at Lu Yuan and said, "How about... how about we try a different approach?"
Lu Yuan smiled and said, "It's alright. This is no problem for me!"
So, before the guards returned, Lu Yuan ran over quickly.
He reached out and slammed his hand down on the concrete ventilation duct that had already been poured.
Then a fist-sized area appeared inside, and Lu Yuan found a fixed object and hung the dimensional crystal necklace on it.
Standing not far away, Qiao Nana covered her mouth and looked at Lu Yuan, afraid that guards would come over at this moment. She was even more nervous than Lu Yuan.
However, just as she glanced outside and turned back, Lu Yuan had vanished from the spot.
"Where...where did he go? How could he suddenly disappear like that?"
Qiao Nana thought her eyes were playing tricks on her, but after looking for a long time, she still couldn't find any trace of Lu Yuan.
