Xiao Chen immediately wanted to pull out the Spirit Snatcher Knife and give it a blow, and Xiao Chen could be sure that once his Spirit Snatcher Knife hit this energy aggregate, this thing would definitely be finished.

However, before Xiao Chen could make a move, he saw that the figure of this energy aggregate gradually became nothing, and then disappeared!

In less than a few seconds, the energy aggregate was completely gone, as if it had never existed!

Xiao Chen was startled, just thinking about whether it ran away, wouldn't it be his reward to be wasted? But then he saw a sign fall from the sky!

That's right! It's the Servant Token! Xiao Chen grabbed the token in his hand!

At the same time, the inventory has also been updated with a new Servant token.

But that's not all, and then Xiao Chen saw that a new prompt appeared in the system!

System Reminder: Congratulations to Ghost Avenger, you have successfully absorbed the ability of Energy Aggregates, and now your Psionic Balance skill has been strengthened, and you will also receive 20,000 Ghost Points!

Xiao Chen was startled, and said in his heart, what is the situation? How could he have obtained the ability of this energy aggregate for some reason?

Xiao Chen hadn't touched this thing from beginning to end, how could he suddenly gain its ability?

But that's the way it is, the energy convergence is now completely gone.

Xiao Chen quickly checked his ghost point inventory, and found that there were indeed 20,000 extra points, and now it has accumulated to 25,400 points, it seems that he can already learn a skill that consumes high ghost points!

Now the situation in this community is very chaotic, and Xiao Chen found that he still hasn't been able to complete the hidden mission to help Liu Kexin so far, not to mention that there are three ghosts who escaped just now, who knows if they will continue to harass the situation here.

This shows that the danger is far from over.

Now it is necessary for Xiao Chen to use the large number of ghost point rewards just now to learn a new trick as soon as possible!

Xiao Chen quickly glanced at the list of skills, only to find that there was actually an "energy assimilation" in the skills.

There is only one word difference between this skill and the "Energy Transformation" rewarded by the hidden mission, which makes Xiao Chen feel that the connection between these two skills is likely to be very close.

In addition, even the psionic balance that Xiao Chen had just learned also made Xiao Chen feel a little suspicious, after all, the number of ghost points required for the exchange of this skill was too small, making Xiao Chen feel that this skill was not worthy of staying on the fourth-level exchange page at all.

But looking at it now, maybe there is something else about this skill that hasn't been discovered!

At least Xiao Chen felt that it would definitely not only have the effect of stabilizing the spiritual energy in the body just now.

Now the ghost points required for this energy assimilation skill are 30,000, and Xiao Chen's current points are not enough for the time being, so his goal is locked on the two skills "Extreme Cold Control" and "Scorching Control" that are second only to the points required for energy assimilation.

These two skills are very much like two different branches of the same type of skill, one cold and one hot echo each other, is it necessary to learn both skills in order to exert the full effect?

Xiao Chen didn't want to hesitate for too long, so he first learned "Extreme Cold Control".

The reason is very simple, Xiao Chen has a part of the cold qi in his body that Qianqian taught him from the obliteration space before, and this cold qi may be able to have some linkage effect with the extreme cold control?

Chill Mastery: The Ghost Avenger can freeze all ghost creatures in the target area, but it will consume all of the Ghost Avenger's psionic energy.

……

The cost of this skill is a bit exaggerated, and it consumes all the psionic energy? This is almost the same as the previous psionic energy burning, and compared to it, his own levitation technique consumes much less psionic energy......

But soon the system rang again.

Bite!

The Ghost Avenger has been detected to have a certain amount of cold in his body, which can greatly reduce the psionic energy consumed by Extreme Cold Mastery.

Then the system shows another "...... in detection"

After more than ten seconds, the specific percentage of psionic energy that reduced consumption came out, and it actually prompted Xiao Chen to reduce psionic energy consumption by 90%!

Originally, it was necessary to consume all the spiritual energy, but now it means that Xiao Chen will only consume 10% of the spiritual energy after using this skill, and he can use it ten times in one breath when he is in a full spiritual energy state.

Although it still consumes more psionic energy than skills such as impact bombs and psionic implosion, it is at least within an acceptable range.

And Xiao Chen knew very well that the effect of this skill was definitely much stronger than the first two skills, and the same consumption of psionic energy burning was a good example.

At this time, Liu Kexin's voice came down from the second floor: "Xiao Chen! Are you still there? ”

Xiao Chen hurriedly responded and asked Liu Kexin to come down quickly.

Liu Kexin quickly ran down: "How is it?" Is it solved? ”

Xiao Chen didn't have the time to explain in detail what happened just now, so he just nodded.

"Then let's go!" Liu Kexin wanted to go down as he spoke, but Xiao Chen hurriedly stopped in front to lead the way.

The next step was much smoother because they didn't encounter any obstacles.

While Liu Kexin restored the power supply, Xiao Chen quickly checked the surrounding situation.

Who could be the person who just cut off the power? Xiao Chen felt that it was unlikely to be the energy aggregate, because that thing didn't look like a master who could pull the brakes......

Judging from the few thugs upstairs just now, it is very likely that they are related to them, after all, these guys are prepared when the power goes out.

However, Xiao Chen had not been able to see any signs of a living person so far.

Well......

Wrong......

Just now, Xiao Chen deduced from the conversation of the four thugs that there were other ghost helpers around them, so ...... Are these ghosts?

Could it be ...... Is it really that energy aggregate?

As soon as Xiao Chen thought of this, he suddenly felt that he stepped on a puddle of soft things under his feet, and when he looked down, he found that it was actually a sticky-thick white lump stuck to the ground!

Then you don't have to look at it...... This is clearly the trace of the ghost after it was destroyed, it seems that there was indeed a ghost who came here to cut off the power just now, but now it has been killed......

And the one who killed this ghost...... Eight achievements are the energy aggregates just now, right?

Xiao Chen now realized more and more that the energy aggregate just now was not only not his enemy, but had taken the initiative to send him skills and ghost points......

Thinking of this, Xiao Chen suddenly remembered that there was a system prompt just now that after absorbing the energy aggregate, the spiritual energy balance skill had been strengthened.

He hurriedly opened the skill bar and glanced at the description of psionic balance, and sure enough, there was a change!

On the basis of the description of the original skill, there is now an extra line of words: this skill can be combined with energy assimilation and energy transformation to generate new skills.

Current Progress: Psionic Balance (achieved), Energy Assimilation (unachieved), Energy Conversion (unachieved)

It seems that Xiao Chen's guess before was really right, energy assimilation is the skill that he hasn't learned yet in the fourth-level exchange interface, and energy transformation is the reward skill for saving Liu Kexin's hidden task at this moment!

Damn it...... I knew that I wouldn't have learned to control the extreme cold just now......

But then it was time for Xiao Chen to use the Extreme Cold Control! For he now heard a man's shout from outside: "Quick! That ghost is inside! He seems to be Liu Kexin's bodyguard! He also killed one of us! ”

This guy's voice is familiar, isn't it the familiar ghost who just ran away?

His grandmother's, Xiao Chen scolded secretly in his heart, he was still regretting letting them run away just now, but now he actually sent it to the door by himself.

Liu Kexin still couldn't hear the ghost speak, but she had already seen the clue from Xiao Chen's reaction, so when Xiao Chen asked her to wait in place, she didn't ask a word, just nodded emphatically.

Xiao Chen first equipped himself with two energy fists with psionic claws, then placed the Soul Grabbing Knife in a position that he could reach at any time, and then returned to the first floor.

At this time, the ghosts outside the building had obviously gathered, and more importantly, Xiao Chen had just reached half the distance and found that he could already see the situation outside through perspective.

There are more than 10 ghosts in total!

The reason why Xiao Chen was able to conclude that they were ghosts was that he could now slightly feel a circle of energy sources that appeared nearby, and secondly, because the figures of these guys were obviously translucent.

I have to say that this perspective technique is really powerful, if only the perspective technique could be used by yourself at will......

The dozen or so ghosts are now moving closer to the location of the building door, which makes Xiao Chen a little surprised, originally thought that these ghosts might have some tactical considerations, but now it seems that Xiao Chen overestimated them.

The moment he saw that those ghosts had gathered by the door, he suddenly raised his hand upward, and then Xiao Chen felt the cold qi in his body suddenly mobilized.

That's right, what he's unleashing is the Extreme Cold Control he just learned!

Xiao Chen felt that the air around him was cooling down at an extremely fast speed, but this cooling area did not remain around Xiao Chen himself, but moved closer to the position of the building door above at an extremely fast speed!

Then Xiao Chen heard the familiar face of the ghost suddenly exclaimed, "Not good! Hurry back! ”

But it was too late, and a large cloud of cold aura instantly froze the area around the door of the building completely, and the dozen or so ghosts did not fall, all of them were frozen in place.

But they haven't been completely wiped out, and even these ghosts can still speak.

They were all yelling in panic, and one of the ghosts was yelling what kind of skill it was, how could they not have seen it before.

The more this is the case, the more Xiao Chen feels that the skills in his system are really amazing, just the skills in this fourth-level exchange page can make them so frightened, so wouldn't the follow-up skills be ruined?

Xiao Chen quickly jumped up, only to see the familiar face ghost immediately shout after seeing Xiao Chen: "What the hell are you doing!" Why do you keep holding us back! ”

Xiao Chen was a little surprised, these guys didn't know their identity?

The familiar face of the ghost continued to roar, "Who is your master! ”

"Lao Tzu has no master." Xiao Chen said disdainfully: "I am the master, I want to ask who your master is now!" If you don't, you're welcome! ”

"Don't!" The rest of the ghosts cried out: "We are all ......"

However, before these people could finish their words, Xiao Chen saw a large cloud of white gas suddenly burst out from behind him, and these breaths wrapped around those ghosts at an extremely fast speed, and then saw that these ghosts turned into green smoke and disappeared one after another without shouting more......

Xiao Chen was startled, and when he looked back, he found that it was Chen Meng who took Duan Xiaoxiao down, which was obviously because the elevator where the two of them were able to operate normally after the power was turned on just now.

However...... It's a fucking bad time!

Chen Meng obviously didn't expect Duan Xiaoxiao's actions, and he was also taken aback at this time.

"You...... What are you doing? Xiao Chen was extremely angry, because just now these ghosts were about to tell who their master was, but they were actually destroyed by Duan Xiaoxiao at this critical moment?

However, although Xiao Chen was very hot, he could only try to maintain restraint.

At the same time, he was also a little surprised, what kind of skill was Duan Xiaoxiao so good just now?

"Xiaoxiao...... How did you beat them all to death? Chen Meng whispered, "We could have asked for some information about them!" ”

Seeing Chen Meng criticizing herself, Duan Xiaoxiao hurriedly said, "I'm sorry...... I don't know why they're so bad...... I couldn't beat them with these skills before......"

Xiao Chen frowned: "What trick did you use just now?" ”

"I don't know...... It's a very simple skill......" While speaking, Duan Xiaoxiao suddenly shot a white light at Xiao Chen.

The speed of this white light was extremely fast, and it smashed on Xiao Chen's body in an instant, but fortunately, Xiao Chen didn't feel too strong, he just felt that there was a slight energy disorder in his body.

Damn it...... Xiao Chen scolded secretly in his heart, saying that this Xiaoxiao didn't care if he would really be wiped out together?

At this time, Chen Meng said: "It seems that she can't really be blamed...... When I came down, I saw the ghosts frozen. ”

Xiao Chen nodded, and then told him about the situation he had just learned about the control of extreme cold.

"That should be the effect of your Extreme Cold control." Chen Meng nodded and said, "I'm afraid that the ghost frozen by you will become extremely fragile. ”

Xiao Chen nodded helplessly.

However, Duan Xiaoxiao may not have done this on purpose, after all, if she was so strong, she should have made a move as early as the underground floor, why wait until now?

Duan Xiaoxiao also continued at this time: "Sister Chen Meng, they are all bad people! You should be dead! ”

Chen Meng let out a soft "um".

However, Xiao Chen found that the current hidden mission was still not completed.
