The voice became clearer and clearer, and Xiao Chen even heard a bit of rhythm from it.

However, the moment Xiao Chen went up to the second floor, the sound of the ball stopped abruptly.

Now Xiao Chen is in the outer corridor on the second floor that was guided by singing for the first time before, with the campus outside the window on the left and rows of classrooms juxtaposed on the right.

A lot of the black fog before was found in these classrooms, but this time the singing crystal doll did not make any singing, Xiao Chen thought that these black fogs might not be able to regenerate, that is to say, in an area, there is actually an upper limit to the ghost points he can obtain through the crystal doll and ghost vision.

Xiao Chen continued to walk forward with the memory of the sound just now, he remembered that the voice just now should have appeared at the end of this corridor, but it was now pitch black, and Xiao Chen had to get close to see it.

This darkness made Xiao Chen very nervous, but in order to find the little girl, he continued to move forward step by step.

It's close!

Something seemed to be shining in the darkness, Xiao Chen squinted his eyes and looked carefully towards the light, and then heard a piercing scream.

The scream was the same as what he had heard in the locker, but this time it was more like it came from his head.

Now Xiao Chen completely understood the state of mind of the security captain at that time, and this piercing scream stabbed back and forth in Xiao Chen's brain like a sharp knife, although it was not an electric shock, but it was even more unbearable than an electric shock.

Then Xiao Chen faintly heard some cries from these screams, and similarly, this cry was not the first time it had appeared, when Qin Yao came here that night to try to destroy the surveillance video, this cry had appeared once.

Fortunately, the two voices did not last long, and after they disappeared, Xiao Chen gradually recovered.

If he could sweat, his clothes would have been wet by now.

After recovering, Xiao Chen checked all the corners at the end of the corridor, but found nothing.

Did you just hear it wrong?

Boom...... Boom......

The sound of the ball is here again!

It's just that this time it appeared behind Xiao Chen, that is, in the direction he just walked over.

Xiao Chen hurriedly looked back, only to see that in the dark corridor, a short figure was patting the ball, it was the little girl!

Through the dim moonlight, Xiao Chen faintly found that the little girl was still facing away from her, exactly the same as when she was guided to find the crystal doll on the first day.

This picture is actually what Xiao Chen imagined when he first entered the building and heard the sound of the ball, but he didn't expect it to come true now!

Xiao Chen forcibly suppressed the fear in his heart, and kept telling himself that he was also a ghost, there was nothing to be afraid of, and then he moved forward again little by little.

But strange things happened again, and he still couldn't get close to the little girl!

Although in his eyes, the little girl had not moved in place, but every time Xiao Chen advanced a distance, he found that the little girl's position had changed inexplicably, and she always kept a distance of more than ten meters from him.

The same is true of the slap of the ball.

Could it be that this time she is going to provide herself with new items? Is it this ball?

Xiao Chen was quite puzzled, but he didn't dare to ask for it rashly, so he could only say tentatively: "That ...... Little Sister ...... Your name is Qianqian, isn't it? ”

The little girl didn't speak, but the ball in her hand stopped, and it seemed that she still heard Xiao Chen's question.

"Are you in trouble? You can tell me and I might be able to help you! Xiao Chen continued to say cautiously, and at the same time tried to get close to the little girl again, but it was still useless...... The distance seemed to be set, no matter how hard Xiao Chen tried, he couldn't get close.

The little girl remained silent.

Xiao Chen hesitated for a moment, and finally continued to approach her back, but at this moment, the little girl's screams reappeared, Xiao Chen felt as if his brain was about to explode, and the surrounding scenery was instantly blurred.

What the hell is this......

Are you going to die a second time?

He felt as if something was about to burst out from the inside out.

The surrounding scenery has also changed from blur to darkness, not to mention the little girl in front of him, Xiao Chen can't even see the things around him clearly now.

He fainted!

……

I don't know how long it took for Xiao Chen to gradually wake up, and found that the sky was still not bright, and he was still staying where he was, the only difference was that the little girl before had disappeared.

No screams, no cries, no balls.

Could it be that everything before was an illusion of oneself?

It seems that this little girl doesn't want to get close to her, but why did she help him before?

At this time, Xiao Chen found that the system in his palm had automatically lit up, which usually means that a new system prompt has appeared.

Xiao Chen hurriedly raised his hand to take a look, and found that it was the head of the moon spirit in the spirit servant column that was flashing.

After clicking on the avatar, two lines of prompts appear.

First line: Congratulations to the Ghost Avengers for earning 100 Daily Ghost Points from the Servants.

Xiao Chen hurriedly clicked, and sure enough, he found that the remaining ghost points had increased to 600.

The amount is still quite impressive! At least that's more than a lot of the main quests!

Xiao Chen thought that the time point of this settlement should be after 12 o'clock, after all, it was almost 12 o'clock before he entered the teaching building, and counting the time of vertigo, it must be after 12 o'clock at midnight now.

The second row is a corresponding quest related to the Luna Spirit.

Servant Mission: Help the Moon Spirit enter the school building and investigate Qianqian's energy traces.

Reward: 20 opinion

Xiao Chen frowned, could it be that Yue Ling didn't go back to the dormitory tonight at all?

In addition, the words "energy traces" that appeared in the task prompt were also mentioned by Qin Yao before.

Toot toot!

The system sounded an alarm, Xiao Chen hurriedly looked downstairs outside the window, and sure enough, he saw Yue Ling swaggering in front of the teaching building, and she was still holding something that looked like an access control card in her hand, but I don't know why, no matter how Yue Ling swiped the card, this door just wouldn't open.

With such a big grin, aren't you afraid of being discovered?

The hint on the mission told Xiao Chen not only to help Yue Ling come in, but also to help her investigate Qianqian's energy traces, which means that Yue Ling has a certain understanding of Qianqian.

Could it be that not only did she know the information of all the living people in the school, but she didn't even let go of the ghosts?

However, since he was hooked up with the little girl, Xiao Chen naturally couldn't ask for it, he quickly rushed to the door of the first floor, and found that Yue Ling was holding a bent wire in his hand and tinkering with it in the keyhole.

Xiao Chen was afraid that she would be discovered after a long delay, so he hurriedly took out the energy key and put it towards the door, and after a light purple light crossed, the door opened.

Yue Ling's expression was slightly stunned, and she muttered in her mouth, "Huh? It's really open.,It looks like I have a talent for burglary.。 ”

What kind of talent is this......

The moon spirit quickly flashed in.

Xiao Chen had to admire Yue Ling's courage, not to mention that she was a girl, and many boys probably didn't dare to enter an uninhabited building alone in the middle of the night.

What's more, not only is there no one in this building now, but there are also ghosts!

After the moon spirit entered, he first glanced left and right, and then took out from his pocket what looked like a miniature version of a tablet, only the size of a palm, and the screen flashed with a faint blue light.

Xiao Chen hurriedly stepped forward to take a closer look, only to find that what was displayed on the screen was actually a flat topographic map of the campus, and what surprised Xiao Chen even more was that the secret passage of the school was also marked on this map! And the secret passage is also distinguished by red!

It's the same as your own system!

What's going on? Could it be that Moon Spirit is also an avenger chosen by the system? But it's not right, Yue Ling is obviously a living person, and he has even just established an energy contract with himself and become one of his spirit servants.

Where is there a living man who is a ghost avenger?

The moon spirit clicked on the screen for a while, and then saw that the screen changed again, and some small points of light began to appear on the original plan, which were unevenly distributed in several places on the plan.

"Qianqian, you're really here." Moon Ling said to herself.

Xiao Chen was startled, and hurriedly glanced around, but he didn't find Qianqian, so he realized that Yue Ling should have just used this device to track down Qianqian's location.

Could it be that those dots represent Qianqian? But there are at least five or six of these points, so it can't be a clone, right?

Xiao Chen thought that these points might be the so-called "energy traces" of Qianqian, and if that was the case, then the function of this device was too powerful.

These points of light were all concentrated in the teaching building, and then the moon spirit further expanded the floor plan to the teaching building.

After the floor plan was enlarged, the content displayed was also more detailed, and Xiao Chen found that even each classroom was marked.

It's advanced enough, if only it could be built into your own system.

Compared to this thing, the campus map I got was completely pediatric.

Yue Ling quickly locked the position of the first point of light, and it was actually in the monitoring room!

After Xiao Chen followed Yue Ling to the door of the monitoring room, he found that the door was closed, and then Yue Ling planned to repeat the old trick and used the curved wire to pound it again.

Xiao Chen still used the energy key to open the door, and Yue Ling is now more confident in his lockpicking skills.

"I can do it all the time, I'm a genius." Yue Ling said to herself.

At the same time, the moon spirit took out a second tool from his body.
