Sure enough, soon Xiao Chen really heard some footsteps approaching them.

However, since Sister Hong received a text message warning just now, this situation has been expected by Xiao Chen.

Xiao Chen hurriedly let Lu Xiaoxi come in and closed the door.

Although Lu Xiaoxi was equally afraid of the situation in the house, he still chose to close the door.

The moment the door closed, Sister Hong exclaimed, "Hey! Xiao Chen! I can't see you again! ”

Sure enough, when Xiao Chen himself looked towards his body, he also found that his body had changed into the regular, translucent form of the ghost before.

Xiao Chen glanced at the location of the door again, and immediately understood.

It turned out that after the door was closed, the energy luster from the reflectors in the outer corridor was also obscured, so that the key factors that made Xiao Chen appear before were isolated.

At the same time, Xiao Chen looked around the classroom again, and sure enough, he didn't find any traces of energy.

Soon Xiao Chen stepped forward to reopen the door, allowing his body to appear again, and then said to Sister Hong: "Those people are here!" There is no hiding place here, and if you want to avoid being discovered, you must be my spiritual servant! ”

"Yes...... Your servant? Sister Hong asked with a frown.

"It's not! It's just a title, I'll make a contractual connection with you so that I can use some special skill effects on you, and making you invisible is one of them! ”

After Xiao Chen finished speaking, he immediately raised his hand and pointed at Lu Xiaoxi's body, and a slender silk thread immediately appeared between him and Lu Xiaoxi, and at the same time, Lu Xiaoxi's body also became illusory.

Then Xiao Chen closed the door with his backhand, and Lu Xiaoxi, like Xiao Chen, disappeared in front of Sister Hong's eyes.

Sister Hong immediately grew her mouth in surprise.

However, at this time, Xiao Chen also discovered another interesting effect, that is, after he released the spirit servant connection, Lu Xiaoxi could also see him normally.

In other words, this Servant connection allows you to see and communicate with the Servant for the duration of the skill.

"Okay!" Sister Hong nodded: "You do it!" ”

Xiao Chen quickly took out the spirit servant token that had been dropped by the "rare" level ghost creature before, and then pointed at Sister Hong.

Bite!

Congratulations to the Ghost Avengers for successfully subduing the new Spirit Servant: Zhang Hong

It turns out that Sister Hong's full name is Zhang Hong.

Name: Zhang Hong

Age: 29

Personality: Sleek, calm, cold, rational

Interest:Playing with men's emotions

Opinion: 20

Forehead...... Xiao Chenxin said that Sister Hong's interests are really different from ordinary people.

In addition, her personality labels are also a bit much.

However, the introduction of the spirit servant column has not been able to find the special effect of Sister Hong for the time being.

Soon Xiao Chen also established a spirit servant connection with Sister Hong, but fortunately, this skill can be used on multiple targets at the same time.

In this way, the three of them entered a state of stealth at the same time, but there was still a hidden danger.

That is, in case the door is opened, the energy luster on the reflector outside penetrates, and the three of them will definitely still be revealed.

So Xiao Chen motioned for the two of them to follow him and hide in a dark corner near the side of the door, at least this side would not be affected by the light outside the door.

Smack!

The lights were also on.

Then there is the sound of the door of the floor being opened.

The footsteps also became clear in an instant, and Xiao Chen quickly identified it, and found that it should be about four or five people.

These people are talking to each other.

"Look carefully!" A man said in a commanding tone, "Look around every corner!" ”

Soon the footsteps dispersed again, and another man said in amazement, "Look! How are there so many footprints here! ”

"Don't worry about it, I've been here for a long time." Said the man who had just given the order.

Xiao Chen frowned, it seemed that these footprints were already a common thing for some people in the building.

But why didn't they clean up these footprints? Is it because it can't be cleaned up?

After a short wait, a man walked into the classroom they were in.

This person had a flashlight in his hand, and as soon as Xiao Chen was about to do it, he found that this flashlight was not the kind of special flashlight that could make ghosts visible, but just an ordinary lighting flashlight.

Xiao Chen immediately breathed a sigh of relief, and at the same time told Sister Hong and Lu Xiaoxi not to be nervous.

The man swept around the room with a flashlight.

Fortunately, there were no cabinets or anything like that in the classroom, and everything was in full view, at least no one could hide it, so the guy with the flashlight quickly left.

"Report! No situation was found! ”

"Report! Search complete! ”

"Report! No anomalies! ”

After receiving the successive reports, the first man to give the order said: "Keep searching!" ”

Then they turned off the lights and left.

At the same time, the time for the spirit servant to connect was also up, and Xiao Chen reopened the door, allowing the reflector outside the door to continue to shine in.

"These people are stupid." Lu Xiaoxi said.

"Don't be careless." Xiao Chen said: "We still have to keep looking!" ”

At this time, Sister Hong said, "Before we entered this house just now...... Isn't there something in the wayway? ”

Sister Hong's words reminded Xiao Chen at once, in fact, Xiao Chen had already thought of this at the beginning, that is, since something was pushed behind the door here, it must indicate that someone was hiding in this classroom.

Is it also invisible?

"Quick! Turn on the detector and take a look! Xiao Chen hurriedly said to Sister Hong.

The reason why Sister Hong was asked to do this was because Xiao Chen suddenly felt some subtle energy aura in the room at this time.

Xiao Chen's perception of other energies was still very weak, so he couldn't be completely sure.

But when Sister Hong turned on the detector, everything became clear, and there was indeed a spot of light in this room!

Xiao Chen's heart sank, and he said that this ghost had also used energy to hide to avoid detection just now, and at the same time hid himself.

This ghost's stealth ability seems to be more advanced than Xiao Chen's, because even Xiao Chen himself can't find out as a ghost.

Sister Hong's face immediately became ugly: "Could it be ...... He's really dead......"

Xiao Chen approached a little bit according to the coordinates on Sister Hong's probe, and then reached out more carefully to probe.

At such an instant, Xiao Chen suddenly felt a sharp burning pain in front of his fingertips, and saw a flash of fire shoot out of thin air.

The burning pain quickly spread from Xiao Chen's fingertips to his arm.

Xiao Chen hurriedly used the psionic protective body to block the further spread of the flames, but Xiao Chen had already found that his arm had become much darker than just now.

Lu Xiaoxi's reaction this time was quite fast, and he had already shone it with a flashlight beam, and Sister Hong on the other side probably didn't want to hurt her lover, so she didn't do anything.

Now I don't care if this is Sister Hong's lover-person, this thing set fire to itself just now, so it must fight back.

Xiao Chen's gaze had already locked on the location where Lu Xiaoxi was shining with a flashlight beam, and found that a person's phantom had faintly appeared over there, but it was not obvious.

Moreover, Xiao Chen felt that this phantom was simply like a gaseous substance, not only vague, but even ethereal.

"Boss! There's something! Lu Xiaoxi shouted.

"Shut up! Stand back! Xiao Chen ordered at him and Sister Hong.

Xiao Chen...... You...... Don't hurt him......" Sister Hong said hesitantly.

"Don't worry." Xiao Chen frowned and said, "I don't know what this thing is." ”

The reason why Xiao Chen said this was because the shape of this phantom had become more and more obvious now, and it didn't seem to be a man.

Soon Sister Hong found out herself, because she had now taken out a flashlight and shone it.

Two flashlight beams hit the ghost at the same time, and the ghost finally couldn't hold it anymore, let out a howl, and quickly dodged to the side.

At the moment when she dodged, Xiao Chen also saw that there was actually a bright silk thread on her body, and when she looked at the end of the silk thread, another person was revealed.

This time this person was not a ghost, because Xiao Chen could not see any traces of energy on his body.

Moreover, this is a man.

"Little Light!" Sister Hong immediately threw herself on the man.

Xiao Chen motioned to Lu Xiaoxi to be optimistic about Sister Hong's side, and he continued to track down the female ghost just now.

This female ghost had been invisible just now, so that even Xiao Chen couldn't find it, but her current figure was completely revealed.

In addition, the female ghost had a silk connection to the man's body just now, and this silk thread looked exactly the same as the connection of the spirit servant she had released earlier.

So...... The reason why this man was not seen by Xiao Chen just now was also because of this skill!

More importantly, after the release of the Servant Connection, this kind of "invisibility" seems to be not only aimed at people in the real plane, but also other ghosts!

However, this is only Xiao Chen's conjecture for the time being.

The speed of the female ghost was not fast, and she was also looking at Xiao Chen at this time.

The appearance of this female ghost is much more normal than the "female ghost" that appeared in the library before, although her face is pale, her facial features are quite normal, and she can even be described as delicate.

She frowned, her hands surging with energy, and she looked ready to attack at any moment.

In addition, the light on the female ghost's hand was golden, which was different from the spiritual energy used by Xiao Chen himself and the cold color he was more familiar with.

"Hey, hey!" Xiao Chen saw that the female ghost was still sane, so he hurriedly tried to communicate: "We are not here to hurt you!" Don't do it! ”

However, before Xiao Chen finished speaking, the golden light in the female ghost's hand turned into a ball of flame and rushed towards Xiao Chen.
