Pouted, with Leng Xuan's skills, it was not difficult to enter this chemical plant quietly. He let go of his senses, cautiously walked to the side of the abandoned factory, and after a few wary glances to make sure he was not discovered, he jumped to his feet and jumped onto a rusty window. Reaching out to wipe the dust off the window glass, you can immediately see the situation inside. I saw a van parked in the factory, and there was no one in the car at the moment, and it was estimated that those people had already left the car.

After observing the group again, Leng Xuan found that the abandoned factory was empty, quiet, and very weird. I can't help but wonder in my heart, why are none of those guys gone?

He frowned slightly, then dodged to the top of the factory and slipped through the vent here. After a while, he was inside the abandoned factory.

Standing on top of an abandoned factory, you can immediately take the whole factory into view. But the result is still the same, there is no trace of the other party. So, Leng Xuan simply jumped from the top of the abandoned factory. He checked in the van and found nothing. After a deep groan, he began to search around the factory. Since the van is parked here, those people shouldn't go far.

The abandoned factory covers an area of more than 2,000 square meters, and there are many discarded machines, many of which have rusted. Moreover, some machines also contain a lot of former production sewage, because no one has cleaned it up for a long time, they all emit a strong stench, and occasionally one or two mice chirp past him, which makes Leng Xuan's nerves tense slightly, but fortunately, he soon calmed down and continued to explore and move forward.

Leng Xuan carefully searched among the machines. However, I still didn't find any useful clues, and I couldn't help but feel distressed.

After calming down, through observation, Leng Xuan noticed that there was only one main entrance and exit in this abandoned factory, and there was no back door, and he didn't find anyone going out from the main entrance just now. So, those people should still be in this factory, and they haven't left. Since they can't be found in the factory, it only means that there is only one problem, there must be an underground warehouse or something in this factory.

Thinking of this, Leng Xuan immediately began to investigate the ground of the factory. Sure enough, it didn't take long for him to find a square iron gate on the ground in a corner of the abandoned factory. He gently pulled up the iron door and listened attentively, only to hear a faint sound from inside, although the sound was small, but with his sensitive ears, he still judged that it was the sound of human breathing.

Leng Xuan was overjoyed, and finally found a place. In order not to startle the snake and let Yu Qingqiu be hurt, he carefully opened the iron door and walked down the narrow staircase. Entering the basement below, there is a corridor. Leng Xuan found that on both sides of this corridor, there were many rooms, and each room was marked with a name, and through those names, these rooms should be the place where the factory used to store chemicals.

Leng Xuan took a step and walked lightly on the corridor. Along the corridor, coming to the end, the voice Leng Xuan's ears heard became clearer and clearer.
