Lin Yun shook his head and said, "I can't guess." ”

It looks like anyone can do it. But Lin Yun felt that there was no need to be obsessed with the identity of a murderer at this time, if it was said that the reason why a murderer killed people was to take revenge. And how many people in this basement are pure good people, as long as they are still alive after the food is completely eaten, who has never eaten human flesh? That hill-like pile of clean and trivial bones, looking at it, you can see that it has fed a lot of people.

"Let's find that black shadow first!" Lin Yun said, and after speaking, she continued to walk down the lower floors.

Ah Fei took one last look at the bones that were hugging each other, frowned and followed Lin Yun.

"How could it not be?"

They searched all the lower floors, not missing a single corner, but they couldn't find any trace of the shadows.

Lin Yun was very surprised, that black shadow obviously couldn't leave the basement, so why couldn't he find it now?

"Maybe there's another exit here. Ah Fei looked at the ventilation duct in the wall, "If that black shadow is small enough, maybe it can climb out of the ventilation duct." ”

When Lin Yun heard this, he immediately took out a wisp of spiritual power and probed into the ventilation ducts, and found that as Ah Fei guessed, these ventilation ducts could be passed, but the place where they went out was not the ground, but the iron line pipes buried deep underground. The diameter of the tin pipe is about the width of an adult's shoulder, if it is not filled with lines, it can allow children and thin women to crawl through it, and Lin Yun found that the tin pipe that was originally full of lines is now empty, and all the lines inside are gone.

Therefore, it is very likely that the little black shadow came out of the tin pipe! Lin Yun did not hesitate to explore the past along the tin pipe, and soon found the place where the tin pipe leads, if she is not mistaken, it should be a tunnel, an abandoned underground railway!

"I found it!" Lin Yun was suddenly a little excited, if nothing else, that little black shadow must have gone to that underground railway, and where would the underground railway lead?

"What did you find?" asked Ah Fei.

Lin Yun said with some hesitation: "There is indeed a way to go elsewhere, there is an abandoned underground railway, but the vent here is so narrow, how can we get there?"

Lin Yun tried to shrink her body, she seemed to be able to get through, but Ah Fei was so tall now, it seemed a little difficult to get through.

Lin Yun's eyes flickered a little, Ah Fei naturally understood the meaning of her words, and he said, "You lead the way in front, I can naturally follow." ”

Lin Yun looked at Ah Fei with some confusion and asked, "Are you sure?"

"Naturally. ”

All right.

So Lin Yun didn't say anything more, but took the lead in crawling into the ventilation duct, when she climbed a distance, only to hear the sound of metal expansion behind her, and when she looked back, the ventilation duct actually widened!

After the ventilation duct widened, Ah Fei's figure climbed in. When he came in and saw Lin Yun looking at him in shock, he couldn't help but raise his eyebrows, and said, "Don't worry, it'll be fine, my ability has already controlled all the surroundings." ”

The corners of Lin Yun's mouth twitched when he heard this, Ah Fei's ability was really against the sky, no wonder she couldn't kill him!

Lin Yun didn't say anything, but turned his head and continued to climb forward. However, then she heard Ah Fei's somewhat regretful voice again.

"However, once I remove the ability, it probably won't be available anymore. If you want to get out, you can only find another exit. ”

Lin Yun: "......"

In any case, they still managed to climb out of the ventilation duct, and from time to time they could hear the rumbling sound of something collapsing behind them, which showed that the ventilation duct that had been inflated by Ah Fei was completely unusable.

But after the ventilation duct, there is also an iron pipe, and the iron pipe is even narrower than the ventilation pipe, even Lin Yun can only crawl over with a prostrate posture, if he forcibly stuffs Ah Fei, a strong man, into it, he will probably be stuck directly.

But this obviously didn't bother Ah Fei, because Lin Yun saw that the iron pipe was inflated in front of her.

Lin Yun was sluggish.

"Come in, my abilities won't last long, and if we collapse later, we'll be stuck here forever. Ah Fei suddenly urged, Lin Yun was a little dumbfounded when she heard it, she felt that Ah Fei was talking nonsense, she didn't believe that his ability would be so weak, if his ability really couldn't last that long, she would have been able to take the opportunity to get rid of his control a long time ago, although she didn't really want to get rid of him now.

But although she complained so in her heart, she obediently climbed in.

The iron pipe is much longer than the ventilation pipe, and after a while, Lin Yun found that fine and dense sweat oozed from Ah Fei's forehead, and she couldn't help but be stunned. Is he telling the truth? His abilities really won't last long?

"You...... Are you okay?" Lin Yun couldn't help but ask with some concern, if Ah Fei really couldn't hold on, she would be fine, Ah Fei himself was going to be trapped here, that would be too bad.

"It's okay, I can probably hold on for five minutes. Ah Fei said nonchalantly.

Lin Yun: "......"

Five minutes?

She silently calculated the distance to the abandoned Underground Railroad, which might have to climb for eight minutes at their current speed......

After Lin Yun was slightly entangled for a while, he lay on the ground and said, "You come to my back, and I will carry you away." ”

Fei: "......"

"Hurry up, what's the rubbing! She didn't want to leave Ah Fei alone in the tin pipe in the end, the person she was looking for hadn't been found yet, but she lost someone first, which was really miserable to think about.

Seeing that Lin Yun was so anxious, Ah Fei couldn't help but sigh.

He said, "Five minutes is just a conservative estimate......

Lin Yun didn't want to listen to his nonsense, she reached out and dragged him up directly, and then said, "Less nonsense!

Fei: "......"

Red face and hot ears.

When they finally got out of the iron pipe, Lin Yun finally breathed a sigh of relief, and Ah Fei, who was carried on her back, was already sweating, and his sweat even dripped onto Lin Yun's neck.

After Lin Yun put Ah Fei down, he couldn't help but wipe the sweat off his neck immediately, because it was too itchy!

Ah Fei seemed to be a little weak because of the excessive energy used by the alien energy, he leaned against the wall and gasped for breath, and couldn't help frowning slightly when he saw Lin Yun's movements.

"What's wrong with your neck?"

"Itchy!"
