The narrow terrain and the dark blue glow add to the mysterious and eerie atmosphere here.

Xiao Chen hadn't heard any suspicious voices yet.

According to the secret passage mark on the map, the narrow passage where Xiao Chen was located would appear after extending forward for about fifty meters, and several forks would appear, and each fork would connect a square of independent areas.

Xiao Chen counted carefully, there were five in total, and the distribution was very even.

In fact, the secret passage structure of the entire underground area of the campus is extended by these five square areas.

Except for these square areas, all the other places were long and narrow passages like a labyrinth, and Xiao Chen always felt that these passages were built on purpose, in order to make the people who tried to break into them lose themselves.

However, with these square areas, Xiao Chen has a priority goal.

He made a simple sequence of the five square areas according to their current distance from himself, and then moved towards the nearest square area.

Soon Xiao Chen discovered that he had to be more careful when walking in this secret passage, even if there was a map, because the closer he was to the concentration of the square area, the more complicated these connected secret passages became.

Coupled with the fact that there is less and less time left for this limited-time hidden mission, Xiao Chen has already taken the wrong path several times in a hurry.

However, Xiao Chen finally managed to reach the location of the first square area, which was an ordinary room from the outside, I don't know if it was because of the blue light, the walls of the room looked gray.

The house has only one door, no windows.

The door looked as old as the house, with a rusty keyhole in the middle.

Xiao Chen first tried to push the door, but found that it couldn't be opened, and then planned to use the energy key to open the door, but this time the key didn't work anymore.

……

Xiao Chen remembered that the description of the energy key was very clear and could open most of the locks, but he didn't expect to encounter this small number of "unlockable locks" so quickly.

Xiao Chen's first reaction was that there might also be a lilac aura similar to the previous one on this door as a barrier to hinder the play of the energy key, but when he hit the thunder bullet in his hand towards the door, he didn't hear the sound of "呲呑", and there was also no lilac breath.

Fifteen minutes are now left, and the system has already sounded its first siren.

Since you can't open the door, you can only force your way in.

However, Xiao Chen was hindered again, and the thickness of this door should be much more than 5 centimeters, because he tried several times and could not succeed.

Xiao Chen was a little stunned at this time, after all, he was just a ghost with weak strength now, if the "privileged skill" as a ghost itself could not work, then he would be a complete waste.

For the first time, he began to take the initiative to pray that Qianqian would show up to help, but unfortunately Qianqian also disappeared this time.

Ten minutes to go!

Now this time is simply not enough for him to go and explore the rest of the rooms, in fact, Xiao Chen can already burn high incense after searching this one room.

There was no way, Xiao Chen could only start to circle around the room, he was already hoping that there might be some secret doors or something around this room.

Halfway through this, Xiao Chen suddenly heard the singing crystal doll in his pocket and began to sing!

This means that there must be a black fog near Xiao Chen now! And it's not far away!

Xiao Chen hurriedly looked around, but he didn't see any black fog.

Is it in the house?

Xiao Chen began to continue to walk slowly along the edge of the room, and at the same time further detected the specific location of the black mist according to the size of the crystal doll's singing, and soon he located a place where the singing was loudest.

This place was close to the edge of the wall, and Xiao Chen felt that there was a high probability that the black mist was behind this wall!

It's only five minutes!

Xiao Chen pressed his hand against the wall, trying to absorb the black mist through the wall, but it was useless......

Three minutes!

As the amount of time Xiao Chen's palm pressed against the wall increased, Xiao Chen found that he gradually developed a new strange feeling.

Although he still couldn't see the black fog, he seemed to be able to feel where the black fog was!

Behind the wall, indeed!

Two minutes!

That feeling was even stronger, and more importantly, he now had an extra feeling of being absorbed by something!

And the source of the adsorption is the black fog behind the wall!

There's only one minute left!

The interface on the system has flashed red, and a warning line has appeared: If the mission fails, the Ghost Avenger will permanently lose the opportunity to learn Ghost Insights.

There was no way back, in fact, from the very beginning of the appearance of the adsorption force, Xiao Chen had already found that he seemed to have an ability that could flash through the wall and reach the black mist directly.

It's just that this ability hasn't appeared in the relevant system skill bar at all until now, and he doesn't dare to use it rashly.

But now that there was no way out, Xiao Chen decided to give it a go.

What's more, even if it fails, it will be just hitting this wall at most.

The adsorption force had reached its peak at this time, Xiao Chen exhaled slightly, which was considered to have strengthened his courage, and then he completely relaxed his body and decided to let the powerful suction force suck himself in!

……

Xiao Chen's body shifted.

Attention, it's a transfer, not a move!

Because Xiao Chen didn't have any feeling of hitting the wall or passing through the wall at all, he just saw that the scene in front of him changed in an instant.

One moment it was on the outside of the wall, but the next it was inside the wall!

At this time, there was a black mist in front of him, and this black mist was more dense and larger than the other black fogs in front of him.

Looks like there must be more ghost points included here!

It's only 30 seconds!

Xiao Chen didn't bother to look at the other layouts in the room, and directly leaped onto the black fog with an arrow step, and because the speed was too fast to brake, Xiao Chen's whole person crashed into it.

Bite!

Limited-Time Hidden Mission: Earn 300 Ghost Points (300/300) in one hour.

That black fog really didn't disappoint Xiao Chen, he actually had 300 points directly!

Bite!

Congratulations to the Ghost Avengers for their new ability: Ghost Insight

Bite!

Congratulations to the Ghost Avengers for mastering their new ability: Ghost Teleportation

Bite!

System prompt: Now that you have met the conditions to open the second level of the redemption page, will you open it immediately?

Yes/No?

The continuous jingling made Xiao Chen feel caught off guard.

Xiao Chen first temporarily closed the system prompt on the Season 2 redemption page, because he needed to take a look at the two new skills he had obtained earlier.

And Xiao Chen saw very clearly just now, one of these two skills was obtained, but the other was actually comprehended, which is also a completely new situation.

The first is Ghost Insight: The Ghost Avenger can perceive the opponent's current psychological state to a certain extent, and the degree of perception will be determined by the Ghost Avenger's own psionic strength and the target's physique.

This skill looks a bit like a weakened version of mind reading, and with this skill, Xiao Chen seems to be able to see through the opponent's mental state in advance like the previous Moon Spirit.

However, this skill also seems to have a lot of limitations, especially since this skill is also related to its own psionic strength. Although Xiao Chen hasn't found out where to check the current psionic strength for the time being, he is only a new ghost avenger now, and he is still so weak, so this psionic strength is definitely not much better......

Therefore, Xiao Chen has prepared for this skill, which will be very weak in the early stage.

And then there's the second comprehension skill, Ghost Teleportation!

This skill feels like a cow just by hearing the name!

He teleported from the outside of the wall to the room just now, it must have been a complete teleportation process, and it was precisely because of this that this skill was successfully comprehended.

Comprehension skills are placed in a separate slot.

The system first gives a concept of skill comprehension: when the ghost avenger is active on the ghost plane, if he can meet the unlock conditions of some special skills, he will comprehend the corresponding skills.

The current comprehension skill bar is a long strip-shaped table, and Xiao Chen saw that in the first row of the table, there was indeed a ghost teleportation skill introduction: the ghost avenger could use the nearby psionic black fog to teleport for short-distance teleportation.

The description of this skill told Xiao Chen two basic knowledge.

The first point is the use condition of the ghost teleportation itself, which must be accompanied by a black fog, and from the perspective of the skill description, this teleportation is still a short distance, so the previous ghost movement still has its value.

The second point is the name of the black fog itself: psionic black fog. Before, Xiao Chen was still thinking about what the concept of psionic energy strength was, but now it seems that the psionic strength is very likely to be the number of ghost points, because after he obtained the psionic black mist, it was the change in the ghost points that was intuitively reflected in the system.

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

There are also many dark cells underneath this skill, which is somewhat similar to the dark avatar of the moon spirit in the spirit servant slot, so Xiao Chen is almost certain that there are more comprehension skills to unlock.

After roughly confirming the situation of these two skills, Xiao Chen began to observe in this room.

The layout of this room looks more like a bedroom, but it is definitely not an ordinary bedroom.

There was a dirty, small bed covered in dust, and on the side of the bed there was an equally dirty bedside table with a gray picture frame on it.

In addition to these, there are only a few standing cabinets against the wall in the whole room.
