For a moment, Xiao Chen had a very strong sense of betrayal in his heart, and he ventured to save Qianqian, but Qianqian herself disappeared.

However, this sense of betrayal was quickly dispelled by Xiao Chen himself.

First of all, Qianqian has helped herself several times before, and they all did it at a very critical time, it can be said that if there is no Qianqian, Xiao Chen would not be able to complete many tasks published on the system.

Secondly, helping Qianqian this time is also part of the system task, and it is also the main task, so it is ...... This may simply be the requirement and arrangement of the task itself.

Thinking of this, Xiao Chen immediately cheered up.

Judging from the footsteps downstairs just now, Xiao Chen could be sure that it was not the two groups of people in black who came in, but only one of them.

In addition, from the voice of the person just now, it is very similar to the voice of a tall bodyguard, which means that the person who comes in now is also the team he leads.

And the reason why the short bodyguard didn't come in must have carried out what the tall bodyguard just said, "disperse and guard all the exits".

Xiao Chen quickly glanced out the window, and sure enough, he found that several places that could be crossed by the intermediate wall-piercing technique were guarded, including several first-floor windows and two side doors.

At the same time, the footsteps in the building were still approaching the second floor quickly, Xiao Chen thought that the other party was numerous, and he had little experience in how to use palm thunder to deal with living people, except for palm thunder, he had no other means of attack, and his strength could not be compared, so Xiao Chen decided to avoid the edge for the time being, and first flashed to a stepped classroom next to him.

Thinking of this, Xiao Chen immediately used the intermediate wall-piercing technique again to enter the classroom, and then stuck to the door and listened carefully.

I thought that I would definitely be able to win a moment of respite after avoiding the edge, but who knew that the sound of those footsteps came to the door of the classroom where he was almost without stopping.

Damn it...... Xiao Chen reacted at this time, the target tracking of these people is actually real-time, and they can find it wherever they go, could it be that these people have some kind of device in their hands that can track ghosts?

"In this classroom!" The voice of the tall bodyguard really sounded: "Someone! Kick the door open! ”

"No." Another person's voice said: "Mr. Wang has confessed, you can't destroy the facilities in the school, otherwise it will be difficult to explain to the people in the school." Besides, it's not a difficult character, so can you be in such a hurry? We just need to keep it from letting him run. ”

The tall security guard immediately agreed, and then he began to order the security captain to be called to open the door.

Xiao Chen quickly stabilized his nervousness, and said in his heart that since these people had tools in their hands that could track their location, and he was completely unsure that he could beat them, then the top priority was to find a way to hide himself!

The main quest only says to help Qianqian get out of danger, and it doesn't require him to defeat the opponent, so as long as he finds a way to get out of here after concealing his whereabouts, he may also be able to trigger the conditions for completing the mission.

The reason why Xiao Chen was able to think of this method for the first time was because after he had obtained the "cheatbook" of the comprehension skill, he noticed that there was a name for the comprehension skill called "Energy Concealment".

Like regular skills, you can't see the description of the skill until you have successfully learned it, but judging from the name of the skill, it is obvious that it is a functional skill that hides itself.

The unlock conditions for energy stash are not the most troublesome, but they are the most special.

The "cheats" reminded Xiao Chen that he must empty all the spiritual energy points in his body within 30 seconds, and attack three people who were hostile to him with his bare hands.

The conditions in the first half were relatively easy to achieve, but the second half was impossible for Xiao Chen at that time, because there were no enemies in the underground secret passage area at that time, which was why Xiao Chen was not in a hurry to unlock the comprehension skill at that time.

Xiao Chen quickly retreated to the window of the classroom, the classroom on this side was facing the direction of the main entrance of the school, and he saw that the previous security captain was running towards the teaching building, obviously receiving an order from the tall bodyguard just now to open the door here.

Xiao Chen calmed down, now was not the time to unlock the skill, because the entire unlocking condition only allowed 30 seconds, so he had to wait until the security captain came to the door before starting.

Soon Xiao Chen judged that the security captain had arrived at the door based on the sound of footsteps and talking, and Xiao Chen quickly sent out twenty palm thunderbolts the moment the key entered the door.

Then Xiao Chen found that he no longer had the ability to continue to condense the palm thunder.

That is to say, the spiritual energy reserves at this stage are probably only allowed for Xiao Chen to hit about twenty-five rounds, because this must also include a part of the spiritual energy he consumed when he entered the door just now.

After the fight, Xiao Chen felt an obvious sense of emptiness in his body, and at the same time, he also found that his strength seemed to become smaller......

Bang Dang!

The door to the lecture hall was kicked open, and the tall bodyguard was poking forward with a small bright instrument in his hand.

Xiao Chen took a closer look, only to find that this device was actually exactly the same as the thing that Yue Ling held before that was used to collect Qianqian's "energy traces"! It's also a tablet-like device.

Then the answer is obvious, the reason why I was discovered must be because of this thing.

Xiao Chen quickly glanced at the instrument screen, and sure enough, he saw that what was displayed on it was a detailed topographical map of the teaching building, but there were no light spots on it.

"Oops! How is it gone! The tall bodyguard was surprised, and then suddenly turned his head and yelled at the security captain: "Did you let her go!" ”

"How dare I ......" The security captain hurriedly waved his hand and said: "And I just came, I have always been by your side, where do I have a chance to let Qianqian ......"

This is a great opportunity! Now that it is clear that this instrument cannot detect itself for the time being, then taking advantage of the civil strife among these guys, it is just time to complete the unlocking conditions in the second half of the stage!

Not to mention, the 30-second time should be almost up!

Xiao Chen quickly leaned against the wall and walked around the tall bodyguard, this tall bodyguard was probably the most experienced in combat among these people, so it was actually the most unwise to attack him.

Relatively speaking, this security captain is much more stupid, and this Wang Balamb also helped Qin Yao deceive the police, Xiao Chen just took the opportunity to take revenge on him!

Then Xiao Chen gestured with a hand knife, and then slashed at the back of the security captain's head.

However, this "fierce force" is only relative to Xiao Chen himself, after all, he only has one-tenth of his strength before his death, plus he lost part of it when he released his spiritual energy just now, this knife should only make the security captain feel that the back of his head was patted.

I saw that the security captain suddenly turned his head and looked back, and a trace of extreme horror flashed in his eyes.

Xiao Chen didn't waste any time, and quickly went around to the other black-clothed people outside the classroom, and selected the two outermost people to give them the back of their heads respectively.

Bite!

Congratulations to the Ghost Avenger for mastering the new ability, Energy Stash.

Energy Stashing: Completely hides all traces of energy from the Ghost Avenger for 30 seconds.

The word "energy traces" appears here, which is the same as the content of the previous Spiritual Servant mission related to the Moon Spirit.

The "energy traces" collected by the moon spirit at that time were indeed detected by that kind of tablet-like device, the only difference is that she didn't detect herself at the time, but now she has been discovered.

Xiao Chen thought that this matter was very likely to be related to Qianqian.

There is also a small label at the bottom of the skill hint: Energy Stashing can be opened by holding your breath.

Hold one’s breath......

To be honest, Xiao Chen really hadn't paid close attention to his breathing after becoming a ghost, and now with the hint of this skill, he was surprised to find that he still breathed like a normal living person.

"Found it! Outside! The tall bodyguard suddenly shouted.

Xiao Chen realized that it had already been 30 seconds since then, and it was estimated that the spiritual energy value he had just emptied had begun to gradually recover, and only then was the position redetected by the instrument of the tall bodyguard.

Soon the other people also looked at him one after another, and Xiao Chen hurriedly held his breath.

"Weird! Why is it gone! The tall bodyguard seemed to be about to get nervous, and then he yelled, "Go ahead!" Carpet Search! ”

Xiao Chen began to run wildly along the corridor, the energy hiding time of the bonus skill was still 30 seconds, he had to leave this teaching building before he arrived in 30 seconds, otherwise he might not be able to get out again.

But if you just run, time is definitely not enough!

Now the psionic energy has recovered a bit, and as the reward content says, Xiao Chen's breath-holding does not cause the loss of psionic energy, so when he activates the ghost movement, it will be successful immediately.

Although the duration of this time was quite short, it still made him rush out of the school building at the last moment.

At the same time, the 30-second time has arrived.

The entrance to the teaching building is now guarded by the short bodyguard, and when Xiao Chen passed by him, he heard the walkie-talkie in his hand ring: "The target has left the building!" Hurry up and track it down! ”

Then Xiao Chen saw that the short bodyguard also took out the same detection device, and Xiao Chen hurriedly hit the device hard.

Although the force was not great, because the bodyguard was defenseless, the device immediately fell to the ground.

But...... The short bodyguard took out a flashlight and shone it directly at his face.
