This voice was so familiar, Cheng Feng knew that this was the person he had been looking for, he was Xiaobao.

Xiaobao's immature voice Cheng Feng will never be mistaken, he has been looking for it for so long but he has not found it, but he didn't expect him to be here.

Cheng Feng hurriedly ran away from the source of the sound, he was afraid that if he was too late, he would disappear again, and it would be more troublesome.

This voice rang out once, but after Cheng Feng approached, no sound came out, which made his search a little more difficult again.

His spiritual sense didn't work, but he couldn't see much with his eyes, and he couldn't see some places, Cheng Feng kept looking for it in a high-rise building.

According to his detection, the voice came from this tall building before, maybe Xiaobao is still here, but he doesn't know where it is.

"Ah" Just when Cheng Feng was constantly searching, a miserable scream came from inside the tall building, but this time Cheng Feng heard it very clearly, it was definitely not Xiaobao's voice.

Because this voice has a deep and strong stamina, it is definitely not a child's voice, but Cheng Feng can still feel that this voice is a little familiar.

He looked up at the top of the building, and saw that there was nothing on it, but he knew that the sound was coming from above.

Cheng Feng hurriedly went upstairs and went up, and it didn't take long to come to a spacious hall, according to his judgment, the previous voice was transmitted from this floor.

But he found nothing here, which was strange, he had heard the sound coming from here, but he had come here and there had been nothing.

"Could it be that they were imprisoned here by others?inadvertently made a sound, and then moved to the place for fear of being discovered?" Cheng Feng could only think of this in his heart, he felt that there was only this kind of explanation.

Otherwise, it can't be explained at all, and it is certainly impossible to say that he heard wrong, and his hearing is not comparable to ordinary people.

"Since there is no one here, it must be up there!" Cheng Feng looked upstairs and muttered in his heart.

Because he came up from below, and he didn't see anyone going down at all, then he could only explain that they went up.

Thinking of this, Cheng Feng sped up and went up, and when he went up several floors again, suddenly another scream came.

Cheng Feng could hear it very clearly this time, this voice was upstairs, and the distance from him was one floor away, so he heard it very clearly.

After determining the position, Cheng Feng galloped up again, and suddenly came upstairs, only to see that the upstairs was still empty and there was nothing, and Cheng Feng's heart was puzzled.

He could clearly hear the sound coming from upstairs, but he hadn't seen anyone for such a short time, how could they run so fast!

Just when he was puzzled, another voice came from upstairs, and now he was very strange, how could it be upstairs again, there was definitely something wrong with this.

Cheng Feng carefully observed this floor and found that there was nothing peculiar, so he galloped up again, and this time he did not stop when he reached the upper floor, but galloped all the way up.

But every once in a while he would hear a scream coming from upstairs, and it was so strange that every time he went upstairs it seemed to be as fast as he was.

Every time he heard a scream it was from upstairs, and he was almost certain that it must have been at the top.

Only when a special sound transmission channel is set up at the highest place, can every time it be a scream from upstairs, and Cheng Feng, who knows this situation, does not delay and goes upstairs directly.

As he went up, the voice came again many times, and it was just as he had guessed, and it confirmed his guess even more.

Half a day later, Cheng Feng came to the top floor, the stairs in front of him had been sealed, and there was no way out, but at this time, the screams stopped.

He didn't have anything to rely on, he searched all over the roof, but found nothing, and now he was really puzzled.

The sound was so strange that it seemed like it was deliberately luring him upstairs, but when he got upstairs, there was nothing.

"Could it be that this is a trap?" Cheng Feng thought suspiciously, but he didn't find anything here, and it didn't look like a trap.

Just as he was about to go downstairs, a figure rushed down the stairs in an instant, the speed was extremely fast, Cheng Feng only saw a shadow, and disappeared in an instant.

Cheng Feng hurriedly followed this shadow and chased after him, and when he went down the next floor, he caught up with this figure, and when he saw this figure clearly, he found that he was Xue Kang.

"Elder Xue, why are you?" Cheng Feng asked with a puzzled expression, how could Xue Kang be here, what about Xue Ling and Xiaobao! This is what Cheng Feng wants to know the most.

"Are you...... Cheng Feng?" I saw that Xue Kang could act as if he didn't know Cheng Feng, and he looked at it for a long time before he said his name.

"Old Xue, what's wrong with you?" Cheng Feng felt that something was wrong, Xue Kang had seen him many times, even if the two hadn't seen each other for a while, it would not be to the point of not knowing each other.

But when Xue Kang first saw him, he didn't seem to know him, which was really abnormal.

"I haven't been here for a long time, and a lot of things are incredible, so my mind is a little delusional. Xue Kang explained with an embarrassed face.

But as soon as he spoke, Cheng Feng's heart became even more confused, because this voice was the same scream he had heard before.

And that scream had been playing hide and seek with him until he reached the top of the building, but later he found out that the person and figure turned out to be Xue Kang.

Then I found that Xue Kang didn't seem to know him, all this was so weird, Cheng Feng, who had seen too many things, had to doubt the authenticity of this Xue Kang.

"Xue Lao is here, what about Xue Ling and Xiaobao?" Cheng Feng asked quietly, he also pretended not to find anything, and continued to ask Xue Kang, wanting to talk to him.

"Xue Ling and Xiaobao?" Xue Kang seemed to have forgotten about these two people, and grabbed one hand on his head several times before replying.

"You're talking about them! I remember, we came in together, and then we were caught and imprisoned, and then I found a chance to escape, and then I met you. Xue Kang's answer did not break the praise at all.

But Cheng Feng saw his flaws at a glance, and he wanted to be so flat before he answered, this was the biggest flaw.

"So I don't know where they are now!I'm looking for them too!" If it weren't for those things before, Cheng Feng might have really been deceived by him.
