Xiao Chen was taken aback by this black shadow, because this black shadow did not seem to have a body, but only two long, narrow arms that emitted black fog, which came out of a thicker black fog.

In short, it's a black mist with arms long......

And more importantly, Xiao Chen found that this black fog was exactly the same as the black fog that appeared on those nightmare servants before, as well as on Liu Kexin's own body and her books!

……

Chen Meng immediately aimed a strong flashlight at the black fog and shone it over, forcing the black fog back in an instant, and retreated directly into the kitchen.

Needless to say, Liu Kexin, of course she can't see this black shadow.

And Yue Ling actually didn't see it just now, because the time for Xiao Chen to connect with her spirit servant had already arrived.

Xiao Chen hurriedly re-established the spirit servant connection with the moon spirit as soon as possible, so that she could also see the location of the black shadow.

The black shadow retreated into the kitchen and immediately let out several strange screams in succession, which sounded a bit like the "squeak" of a monkey.

Then there was a "clang" smashing sound.

Yue Ling could now hear the sound it was making, and at this time, he asked Xiao Chen with a puzzled expression, "This thing is going to run?" ”

Xiao Chen also felt that this was the case, and felt that after it was photographed just now, it wanted to break out of the window.

Xiao Chen hurriedly motioned for Chen Meng and Yue Ling to cover him with flashlights, and then Xiao Chen rushed to the kitchen first.

The moment he entered, he saw the bodyguard who fell to the ground, this was the same bodyguard at the north gate before, and now he couldn't tell whether he was dead or alive, but he didn't seem to have any obvious external injuries on his body.

The elder's ghostly monster with two smoking arms had already opened the window.

Xiao Chen hurriedly flew over with a shock bomb, hitting the target accurately, and then the monster let out another "squeak" scream.

Before Xiao Chen could react further, it had already fled out of the window, and by the time Xiao Chen fired the second impact bullet, it had already run farther away.

In addition, Xiao Chen didn't seem to be able to fix it with the binding book, and the thing disappeared into the night.

"Ran away?" Yue Ling also followed at this time.

Xiao Chen nodded.

Chen Meng and Liu Kexin also entered the kitchen afterwards.

"It seems that the ghost creature is not too aggressive." Chen Meng said.

"Of course it's gone, because you forced her back with a flashlight!" Yue Ling said.

However, Chen Meng shook his head with certainty: "No, I can feel it...... This ghostly creature has no desire to attack in the first place. ”

"And what is it doing with its arms outstretched?" Xiao Chen was also a little skeptical.

"You'd better see if it's included in the Ghost Guide." Chen Meng pointed to Xiao Chen's left hand.

Xiao Chen then remembered the matter of the Ghost Illustrated Book, and hurriedly opened the system and began to check.

Liu Kexin, who was next to her, immediately became interested after hearing this: "What? Do you also have a ghost book? Let me see, we might be able to learn from each other and add to the content of the two books. ”

"I'm not a book ......," Xiao Chen said helplessly, "This is part of the system." ”

"Oh......" Liu Kexin looked obviously disappointed: "It would be nice if I could also see your system." ”

Since Liu Kexin was a living person and was not Xiao Chen's spiritual servant, the left hand he saw Xiao Chen was just an ordinary palm.

"If you want to see it, you can do it." Moon Spirit said, "You can become his spirit servant. ”

"Servant?" Liu Kexin's eyes instantly opened: "You mean...... Can you make the living your spiritual servant? ”

Xiao Chen looked at Liu Kexin's expression and found that she obviously knew something about the matter of the spirit servant.

Xiao Chen nodded.

"So you're his spiritual servant?" Liu Kexin looked at Yue Ling and asked.

"That's right." Yue Ling nodded: "It's not just me, Chen Meng is also his spirit servant, and there are two other people, but you don't know each other." ”

"Sister Liu...... Do you know something? Chen Meng asked sharply.

Liu Kexin really said "um": "This is still the information I found when I collected the ghost illustrated book!" I even thought it was someone else's story. ”

"What's the story?" Xiao Chen frowned.

"That is...... There are some identities and abilities and their special ghosts, there is a way to establish a contractual connection with the living, and then link some state bindings between the living and the ghost itself, which can not only enhance the ability of the living, but also strengthen the ability to form the ghost itself. Liu Kexin said word by word.

Every word Liu Kexin said was exactly the same as Xiao Chen's current understanding of the spirit servant......

"How did you make the contract?" Liu Kexin asked.

Xiao Chen also noticed that Liu Kexin seemed to be a little nervous when she asked this, feeling that the ghost creature recorded in her ghost book was terrifying.

"I was rewarded with two Servant Tokens in the system mission." Xiao Chen said: "This token can be used on most living people, and after using it, they can become my spirit servants, but there are also people who are not affected by this token. ”

For example, Qin Yao is one of the people who is not affected by the token.

Liu Kexin nodded: "What about the other two?" ”

"The other two...... They are all obtained through the system, one is automatically obtained after I turn on the Servant system, and the other is obtained through the corresponding Servant task. Xiao Chen said truthfully.

Liu Kexin nodded again, then touched her chin and said thoughtfully, "So...... These servants of yours have something to do with your system, don't they? ”

"That's right." Xiao Chen replied.

"Hmm...... Then I understand......" Liu Kexin still looked a little cautious.

At this time, Chen Meng took the initiative to ask again: "Sister Liu...... What does that ghost creature that you have included in your ghost book look like that can take in spirit servants? Is it humanoid? ”

Liu Kexin actually shook his head: "It's not humanoid...... It is in the form of a fierce beast, similar to the combination of a tiger and a lion, and it looks very strange, and I once thought it was an image in Western mythology...... Moreover, its method of grabbing spirit servants is very cruel, it first kills the living, and then makes those living people become its spirit servants through blood contracts. ”

Hearing this, Xiao Chen understood why Liu Kexin had such a demeanor just now...... After doing it for a long time, she was just wondering if Chen Meng and Yue Ling were also killed by Xiao Chen......

Liu Kexin changed his words and said: "But Xiao Chen just said that his spirit servant was obtained through the system, and it should be controlled by the main god of a higher level, and it was he who gave you this ability." ”

After Xiao Chen roughly understood Liu Kexin's explanation of the spirit servant, he continued to open the ghost illustrated book, and sure enough, a new ghost creature was updated.

Name: Sentinel of the Void

Rarity: Rare

Synopsis: A ghostly creature with low attack power and timidity, rarely initiating attacks, and preferring to walk alone.

Note: This creature cannot be hit by Controlled spells.

……

Xiao Chen felt a little strange.

If you look at this thing purely from the introduction, it's basically a harmless ghost creature for humans and animals, but this creature with low attack power actually likes to walk alone, so what is the meaning of its existence?

Also, what is this void sentinel in the kitchen doing just now? Could it be that you happened to be passing by?

At this time, Chen Meng gave a possible explanation, she said that judging from the word "sentinel", this creature is likely to exist as a surveillance or tracking target.

This is possible, as it is mentioned in the note that it can't be hit by the control skill, so as long as it wants to run, there is really no way to take it under normal circumstances.

Xiao Chen had a blast bomb hit just now, but this sentry was not affected too much, which means that although its attack power is low, it is not as fragile as the Nightmare Demon Servant and the ghost bugs and ghost wolves before it.

Is this thing here to spy on these four bodyguards?

At this moment, the moon spirit suddenly said strangely: "No, the energy on their bodies is very weak." ”

Xiao Chen hurriedly glanced at the detector, and sure enough, he found that although the previous light spot on the screen was still there, the brightness was much dimmer.

"I don't think the light just now is from this bodyguard at all!" Moon Spirit continued, "It's that sentinel's energy at all! ”

"But those bodyguards also have energy in them." Xiao Chen asked suspiciously.

"That's different." Yue Ling immediately shook his head: "The detector's detection of energy is limited in scope, the weaker the energy, the shorter the distance required for exploration, just now we have detected the energy in the villa at the north gate of the school, I thought it was strange at the time, because I know these bodyguards very well, and their energy is logically not enough to be displayed at such a distance." ”

Chen Meng also said: "Yes, the reason why we were able to find it so quickly was entirely because of the second high-intensity energy source, and we had also counted the number of light spots at the north gate at that time, and there was only one in the villa area, so the energy of this bodyguard at that time was actually not displayed at all." ”

Liu Kexin actually added: "Hmm...... I also know about the detector, if I'm not mistaken...... Most living people have to be within 10 meters of energy to be detected. ”

Xiao Chen frowned, and said in his heart In this way, this sentry not only did not play the role of hiding the bodyguard, but was also exposed?

"Ahem......"

At this time, the bodyguard coughed, and Yue Ling hurriedly reached out and pulled him up.

The bodyguard's physical fitness was not bad, and he soon opened his eyes.

"Hey! What happened to you guys before? Moon Ling looked at him and asked.

The bodyguard's face was full of doubt.
