It wasn't until Zhou Yi came to the rooftop that he found that there was no sign of anyone else on the rooftop, and there was a protective fence built on the edge of the rooftop. **Fast Update**

It was built to prevent someone from accidentally stumbling.

It's just that although the rooftop has a protective fence, because it is still less than half a person high, Zhou Yi still has to sneak on the rooftop.

Zhou Yi didn't dare to miss a corner, and walked around the empty rooftop again and again, until he was a little bored with himself, so he leaned against the wall and sat down on the ground.

"Alas, where did the master seal that group of fire ghosts, but don't run out of the range of these four dormitories." Zhou Yi said that, and saw him pat the dust on his buttocks, and then walked towards the iron plate on the rooftop.

I saw Zhou Yi crawling near the iron plate, and pulled the iron plate open a small crack.

Next, Zhou Yiwei hurriedly returned to the sixth-story platform through the iron plate.

Instead, he first passed through this small crack, listened to the sound of the six-story corridor, and then glanced at the scene in the corridor.

It wasn't until he was sure that there was nothing unusual in the hallway that he widened the gap and climbed the ladder embedded in the wall with great dexterity.

The reason why Zhou Yi did not jump directly from the iron gate to the ground was because he wanted to close the iron gate above his head tightly and erase the traces of "crime" left by himself as much as possible.

Zhou Yi returned to the sixth floor of the dormitory, and then picked up the cleaning tools he put aside, and prepared to go down to the fifth floor to carefully search for whether there would be an imprint inside the five-story corridor.

I saw Zhou Yi walking downstairs with a mop in one hand and a broom and dustpan in the other.

However, Zhou Yi only took the first step when he suddenly heard an exclamation coming from downstairs.

The first time he heard this sound, Zhou Yi didn't even think about it, so he immediately dropped the cleaning tools in his hand and ran downstairs quickly.

If it was just an ordinary exclamation, it would not have attracted Zhou Yi so much attention.

The main thing is that it was none other than Cao Yun who was left downstairs to make this sound.

Because Zhou Yi was very worried about Cao Yun's safety, although he was speeding at a speed of three steps and two steps, he was still too slow.

He actually started jumping down the stairs of seven or eight or eight or nine steps.

Although this behavior was very dangerous, it couldn't stop Zhou Yi's anxiety.

After about a minute or less, Zhou Yi immediately followed the voice to Cao Yun's side.

I saw Cao Yun at this time, with his hands touching the ground on all fours, his legs bent, and he was sitting at the staircase of the first floor of the stairs.

Zhou Yi looked at Cao Yun's pale face, and immediately walked quickly to Cao Yun's side, and at the same time stretched out his arm, picked him up and asked, "What's the matter, what's going on?" ”

When Cao Yun heard this, he only frothed at the mouth, but did not answer Zhou Yi's question.

However, Cao Yun also knew that Zhou Yi was concerned about himself, so he stretched out a hand tremblingly and pointed towards the back of the stairs on the first floor, which was full of debris.

Because he didn't know what Cao Yun meant, Zhou Yi had to frown secretly.

Then, I saw Zhou Yi holding Cao Yun and coming to the dormitory administrator's lounge.

But the room was empty, and there was not a single person.

Seeing this, Zhou Yi couldn't help but murmur, "It's work time now, why isn't the dormitory manager in the house?" Is it patrolling? ”

As soon as Zhou Yi thought of this, he immediately rejected the idea.

The reason is very simple, because Cao Yun's call just now was so loud, he heard the sound on the sixth floor, and he didn't believe that the dormitory manager couldn't hear the sound in the building.

For a while, Zhou Yi even began to wonder if they had strayed into some maze.

However, looking at the appearance of Cao Yun next to him, he didn't look like a dummy at all.

Next, I saw Zhou Yi caressing Cao Yun's back and asked again, "Old Cao, what happened just now?" Tell me when you take a breath. ”

When Cao Yun heard this, he immediately swallowed heavily, and after taking a few deep breaths, he replied with a little stumbling: "Voice, voice, I heard a voice just now." ”

"Voice?" Zhou Yi was very puzzled by Cao Yun's answer.

"Just now, just when I was inspecting the building, I suddenly found a glimmer of light in the place where the debris was stacked on the first floor of the stairs, and I suspected that there might be something, so I was going to reach out and grab it, but before I could reach far with my hand, I was scratched by a cold thing." Cao Yun said, and handed the injured position of his hand to Zhou Yi's eyes.

Because Zhou Yifang was too concerned about Cao Yun's safety, he directly ignored Cao Yun's injuries.

It wasn't until Cao Yun brought it up that Zhou Yi discovered the wound on his hand that was still bleeding.

As soon as Zhou Yi saw the wound on Cao Yun's hand, he immediately ran out of the lounge, as if he had forgotten that Cao Yun still had something to say.

When he returned, he suddenly had a wet towel on his hand.

Zhou Yi used a towel to carefully wipe the soil stains next to Cao Yun's wound, and then helped Cao Yun wipe off the blood stains.

After Zhou Yi finished this series of actions, he continued to ask the question just now.

Cao Yun then told Zhou Yi what he had just experienced.

It turned out that as soon as Cao Yun found that there was a bright light suddenly under the debris, he was puzzled, so he immediately bent down and stretched out an arm, ready to touch what was under the pile of debris.

Who knew that he Cao Yuncai stretched his arm close to the gap under the debris, and was cut by a sharp object in his palm.

Of course, if it was just like this, Cao Yun would not have let out such a loud exclamation.

The main reason was that not long after he pulled his injured palm back from the clutter gap, he suddenly heard a voice of thanks coming into his ears.

Imagine how you would feel when there was no one around, and a voice coldly drilled into your head?

Therefore, after Cao Yun was frightened, he let out such a terrible scream.

As soon as Zhou Yi heard this, he hurriedly grabbed Cao Yun's arm and asked, whether the voice was male or female, whether Cao Yun had seen him, what did he say to Cao Yun, and so on.

However, due to the suddenness of the incident, the voice only said three short words, "Thank you".

So Cao Yun can't tell whether this voice is male or female.

It's just that Cao Yun told Zhou Yi with great certainty that once again, as long as Cao Yun heard that voice, he would definitely be able to recognize it.

When Zhou Yi heard this, he could also hear that Cao Yun felt guilty that he didn't recognize this person's voice.

However, Zhou Yi immediately changed the topic and continued to ask: "By the way, you just made such a loud noise, didn't the dormitory manager come out?" ”

As soon as he heard Zhou Yi ask this question, Cao Yun sighed, "Yes, before you went upstairs, I saw the dormitory manager in the house, why did the person disappear in the blink of an eye?" ”
