Now there are actually a lot of options on the second-level exchange skill list that seem to be able to be used as attack skills, but Xiao Chen doesn't dare to take this risk now, because he only has 550 ghost points now, and he can learn two new skills at the same time at most.

Until now, Xiao Chen still didn't know the consequences of mission failure, so he still had to minimize the risk of failure.

Therefore, it seems that upgrading the palm mine is the first option.

Xiao Chen immediately clicked the button to upgrade and redeem.

Bite!

The palm thunder has now been upgraded to LV2, and the damage has been increased to a certain extent.

The specific description of the skill is still vague, but it is not very relevant, because he can quickly verify it through the actual situation.

Now that those fire-extinguishing sparrows had jumped over Xiao Chen's head and flew into the library, Xiao Chen hurriedly used a short distance of ghost movement to chase after him, and at the same time gathered a cloud of palm thunder in his hand.

This light was really much stronger than the previous first-level palm thunder, and Xiao Chen could even hear the faint sound of "Nga Xuan" electricity from it.

Then Xiao Chen aimed at the sparrows flying in the front and smashed the thunderbolt fiercely.

Crackling!

After a burst of explosion, the sparrows in the head really quickly planted towards the ground, and the sparrows that had been locked by Xiao Chen before were the main attack target had already turned into green smoke and disappeared before they even landed.

Xiao Chen immediately had a bottom in his heart, and now that he had learned the second-level palm thunder, these sparrows were actually the same as the two previous ghost insects in his eyes.

Soon Xiao Chen repeated his old tricks and quickly solved the remaining fire-fighting sparrows.

At this time, the flames in the library were still continuing, and Xiao Chen could already feel the temperature of the flames even at the gate.

Xiao Chen looked out again, and there were no more fire-extinguishing sparrows flying, but there was no hint of completing the task, and the task reward had not yet arrived.

Is there a follow-up?

Xiao Chen hurriedly rushed back to the second floor, and after going up, he found that the fire was indeed "smart", although the fire was not small, but it did not affect other books, only the books of Wanli Dragon City were ignited.

Moreover, Xiao Chen found that in the process of burning these books, there would be some sporadic black mist coming out of the flames from time to time.

These black mist were not black smoke at all, but they were exactly what the black mist of spiritual energy looked like, but they could not be absorbed by Xiao Chen either.

And if there were other people near here now, they wouldn't be able to see the black fog.

Xiao Chen only thought of this, and suddenly heard the voices of several people from the window on the second floor in front of him: "Hurry up and put out the fire!" But don't be too loud! ”

Looking at the location where the sound came from, it turned out that there were several young young security guards standing near the entrance of another building on the second floor, who should have taken a shortcut through the back door of the library.

Xiao Chen remembered that the location of the back door was not covered by the surveillance, and estimated that they were deliberately avoided at the behest of the security captain.

These people all had fire extinguishers in their hands, but they didn't do it immediately, but waited and watched.

Because...... They had also discovered the peculiarity of the fire, and several security guards were questioning each other, asking why the fire had burned so strangely, and that there was neither any trace of smoke nor smell.

At this time, the walkie-talkie of one of the security guards rang, and Xiao Chen heard the voice of the security captain, who told the security guards to act quickly, and said that if they couldn't put out the fire, they would all be fired.

These security guards were in a hurry and hurriedly picked up fire extinguishers and prepared to do so.

Xiao Chen naturally couldn't let them get their wish, so he shot a palm thunder at each of these security guards before they could make a move.

However, when this palm thunder is dealing with living people, its power seems to have decreased a lot.

The security guards paused after being hit, then looked around.

Apparently not too hurt, but they were startled by the sudden noise.

"What was it just now?" A security guard looked wary and asked, "Did anyone see it?" ”

"Do you feel like you've been hit by something!" Another security guard said.

These security guards now showed a very frightened look in their eyes, Xiao Chen guessed that they should be different from the previous logistics administrator, that administrator may know some of the actual existence of ghosts, but these security guards definitely don't know.

However, this is actually a good thing for Xiao Chen, human beings themselves have a natural fear of all kinds of unknown things, so that Xiao Chen can make them scared and flee as much as possible.

After all, there is no grievance between these security guards and Xiao Chen, and if they can solve the problem in a relatively "peaceful" way, it is also what Xiao Chen hopes to see the most.

However...... These security guards didn't know if they were young and vigorous or that the newborn calves were not afraid of tigers, in short, after they were hit by Xiao Chen's palm thunder a few times, they actually did not retreat but advanced, and some of them even opened the safety bolt of the fire extinguisher.

Toot toot!

At the same time, the system sounded a warning.

The power of the palm thunder is not very good now! It may still be possible to fight against creatures on the ghost plane, but it is much worse against living people in this kind of reality.

Xiao Chen still had 350 ghost points left, and he quickly checked the remaining skills in the second-level exchange interface, and found that only the two skills of psionic extraction and psionic corrosion could be learned, both of which only needed 300 points.

However, judging by the name...... These two skills really don't look like they can attack enemies, but are more in the direction of support.

Damn it...... Xiao Chen regretted it a little now, he had already learned that his strength had been enhanced, and the improvement of his strength was the most intuitive for him, because this power could also be applied to the reality plane in a similar way.

However, there is no option to withdraw in the system, and he can only settle for the next best thing......

Since you refuse to retreat, you can only continue to scare you with the skill of clone confusion!

Thinking of this, Xiao Chen immediately cast a psionic copy on himself for the third time, and soon an image of Xiao Chen appeared beside him again.

In order to maximize the effect of intensifying the fear, he deliberately "placed" this clone directly opposite the security guards, and it also happened to be wrapped in flames, and the clone was completely like it suddenly emerged from the fire.

A figure appeared out of thin air in the fire, and anyone else would be frightened away, and then these security guards could no longer be calm, they threw down the fire extinguisher in their hands, and then fled in a hurry.

It's time to finish it, right?

However, when Xiao Chen looked down at the task, he found that it was still in an "unfinished" state.

Toot toot!

The system issued a second warning!

Normally, this means that the mission is on the verge of failure, Xiao Chen hurriedly looked around, but did not see more security guards appearing, and the fire-fighting sparrow did not reappear.

However, Xiao Chen soon heard some very slight footsteps nearby, which were very brisk and fine, like a person trotting on tiptoe.

After Xiao Chen turned into a ghost, he had actually noticed that his five senses had more or less improved, especially his hearing, and now it was still very quiet except for the small sound of the flames, so although the footsteps were slight, they were quickly captured by Xiao Chen.

"Giggles!"

Then Xiao Chen heard laughter!

"A lonely ghost deserves my help." This time it was a man's voice.

Xiao Chen was secretly taken aback, judging from this person's tone, he could obviously see himself, could it be the kind of "professional" who held a visible flashlight?

When the voice appeared just now, Xiao Chen had already captured the specific location, just behind the bookshelf opposite him, which was also the direction in which the security guards fled just now.

Xiao Chen quickly chased behind the bookshelf, and then saw a vague figure.

That's right! It's translucent!

It should be a young man in his thirties with a mustache.

However, before Xiao Chen could see more details of this person's appearance, he saw that his figure suddenly shifted sideways, and then disappeared.

What the heck......

Ghost teleportation? Or is it ghost moving?

Before Xiao Chen could think about it, he heard a whistling wind behind him, and when he hurriedly looked back, he only saw a cloudy mist balloon smashed directly into his chest.

Xiao Chen hurriedly dodged and dodged, but he was still a step too late, and the ball with yellow mist smashed on Xiao Chen's side waist, Xiao Chen only felt a heat wave rolling in his body, as if the spiritual energy in his body was disrupted.

Damn it! No wonder the mission wasn't completed, there was one of the toughest guys to deal with!

"Giggles!"

The man was still laughing, Xiao Chen didn't know the strength of the opponent yet, so he quickly retreated towards the staircase where the security guards had just left, and after hiding in the corner, he immediately called up the ghost illustrated book, intending to see if he could find that person's weakness through the illustrated book.

But the Pokédex has not been updated at all.

At this time, Xiao Chen remembered that the guy just now was probably just another ghost who belonged to the "same kind" as himself, and of course it would not be recorded by the ghost illustrated book, because the illustrated book recorded the "ghost type", not every ghost creature would be written.

Then the mustache spoke again: "Giggles! Let me think about how to make you go up in smoke! ”
