The strength of this secret door is worse than the wooden door at the entrance to the attic, and it is estimated that it will not last even half the time in front.

Previously, the entrance of this secret passage was protected by lilac energy, but since Xiao Chen erased these energies for the first time, the entrance here was no different from an ordinary entrance.

Xiao Chen hurriedly picked up Liu Kexin again, Yue Ling carried Chen Meng on his back, and they began to continue to march towards the depths of the secret passage.

Soon they arrived at the entrance to a puzzle in the middle of the secret passage, which was also the final location of Xiao Chen and Yue Ling's search of the secret passage before they found Chen Meng and Liu Kexin.

Because they just saw that the entrance to the puzzle here showed no signs of being moved twice.

But now they had to enter from here, and Xiao Chen remembered very well that the entrance to the secret passage here could lead directly to his ghost home.

In this way, it also saves the trouble of being discovered by other people or monitoring when carrying Liu Kexin and Chen Meng.

The puzzle here had already been solved by Chen Meng himself last time, and the principle was clear to them, so they solved it easily this time.

The moment it was cracked, Xiao Chen heard that the secret door at the entrance to the attic had indeed been breached, and a large number of small footsteps began to chase them along the secret passage.

The entrance to this puzzle should be considered the last line of defense, but it is estimated that it will not last long.

In this way, once they break through the last puzzle entrance, these nightmare servants will invade his ghost house, and Xiao Chen doesn't know what the impact of these things will be if they invade.

After all, there were too many of these guys, and Xiao Chen was afraid that his ghost house would be destroyed, which was why he didn't choose to go directly to the secret path at the beginning.

But there is no other option.

"What are those four bodyguards doing?" Xiao Chen said angrily to Yue Ling, "How long has it been!" ”

"I guess it's outside the library." Yue Ling also frowned and said, "There are too many of these things, and we can't completely count on the four of them!" ”

While speaking, Yue Ling also shook her mobile phone in front of Xiao Chen's eyes and said, "There is no signal here!" I can't reach them either! Let's go back in! Saving Chen Meng and this woman is the key! ”

Xiao Chen nodded at this time and began to continue to run towards the depths of the ghost house.

Inside the Ghost House, Xiao Chen's spiritual energy recovery speed had already begun to accelerate, although it was far less amazing than in his lounge, but it was already a hundred times stronger than when he was in the attic just now.

As a direct consequence of this, the severity of his vertigo began to increase exponentially!

Xiao Chen was now completely convinced that the spiritual energy in his body was proportional to the degree of vertigo, and there was no way, he could only use the spiritual energy diffusion every few steps he ran to achieve the effect of temporarily relieving the vertigo.

This kind of nightmare demon servant is really annoying, but Xiao Chen thinks that this is actually because there are too many of them, if there are only a small number or even a single demon servant, this kind of vertigo should not become too big a climate.

On the way, Xiao Chen also used the construction system of the Ghost House to get the guardian back, and asked him to guard the main passage to his lounge.

At this time, they had already arrived at the door of the lounge, Xiao Chen put the two of them in the room and waited for a while, but there were no obvious signs of improvement, and even the two of them failed to disperse energy.

Then Xiao Chen asked Yue Ling to stay here, and he himself went to the plant cultivation room to get some psionic grass and poison repellent grass, and even brought baby grass by the way, but it was useless.

Especially the doll grass, there was no reaction to the symptoms on Chen Meng and Liu Kexin.

Damn it......

Xiao Chen was a little flustered.

At this time, the moon spirit took the detector and said in a suspicious tone: "Something is wrong! Those four people don't seem to have made a move until now! ”

"Really?" Xiao Chen asked, "How do you know?" ”

"See for yourself." The moon spirit pointed to the energy display screen of the probe and said, "The concentration of energy has not been reduced at all, if they make a move, then even if they don't destroy them all, they will have to reduce the overall energy of those ghost creatures, right?" ”

Xiao Chen took a look at it and found that it was really true, and not only did it not weaken, but it seemed to have strengthened a little! It feels like more Nightmare Servants will join in the future.

Damn it! This is so unreliable! Could it be that these four guys saw that the number of ghost creatures in their target was too large and chose to flee on their own? After all, they are just some guys who take money to do things, and when the catastrophe is really coming, it is impossible for them to work hard for the moon spirit.

However, Xiao Chen still felt that things were not so simple, because at the beginning, the bodyguard at the north gate spoke in a relaxed tone, feeling that these demon servants were not worth mentioning in his eyes.

There is also the kind of "energy grenade" that Ding Wu used before, that thing can form a range of killing effects on pieces of ghost replicas, so since these bodyguards are professional in dealing with ghosts, they should have similar tricks.

What's more, these demon servants have already written very clearly in the psionic guide, that is, some units that are very vulnerable in their own right, even if there is a weapon with a power that is only as powerful as the grenade used by Ding Wu, it should be more than enough to deal with them.

Does that mean...... Are these four people in trouble themselves?

Xiao Chen was still thinking about it, when he suddenly heard a slight but clear collision sound from the end of the passage in the distance, and it was obvious that the metal crossbar under the entrance of the puzzle had been pushed away!

They've finally broken through!

It just so happened that at this time, because Xiao Chen had been in the lounge for too long, the spiritual energy in his body had recovered greatly, and now he began to dizzy violently again.

Xiao Chen hurriedly jumped outside the house and cast the spiritual energy spread again.

The sound of small footsteps approached further, and it was estimated that it would not take a few minutes to reach their location, and then Xiao Chen's only recourse seemed to be to shrink into the lounge...... But at that time, once the door to the lounge was broken, they would never recover.

This door is not unbreakable, because the previous black-clothed bodyguards had tried to destroy it with cold air, and if Xiao Chen hadn't blocked it in time, these doors might have ceased to exist long ago.

So hushing in the break room is not only not a good idea, but it is also a bad idea to kill yourself.

Do you want to take a detour and exit in the direction of the storage room now?

As soon as Xiao Chen thought of this, he was horrified to find that there was also a sound of broken footsteps from the direction of the entrance of the secret passage in the storage room!

Even the Moon Spirit heard it!

"Can these things find the entrance to the locker on their own?" Yue Ling was surprised: "Could it be that someone is directing them!" ”

Xiao Chen frowned: "Will your four bodyguards have been bribed!" ”

"It shouldn't be!" Yue Ling shook his head: "Those people still have their own work ethic!" It's unlikely that they would do such a thing, because when my brother complains, the bodyguard company will definitely punish them severely. ”

Although Xiao Chen still felt puzzled, he didn't have time to care about it now, he had to find a way to defend now!

Then his gaze fell on several defensive buildings in the Ghost House construction project, after all, defensive buildings are not affected by vertigo......

This is Xiao Chen's last resort, using the defense system of the ghost house itself to resist, the reason why it is said "last" is because this thing needs to be exchanged with ghost points, and he originally wanted to save up first to open the next level of skill exchange.

So far, Xiao Chen has seen three types of defensive structures that can confirm their power: Psionic Tower, Cold Tower, and Lightning Trap.

The first two towers have a single high attack, and the other is a group slowdown, and the attack power is almost negligible, so it seems that neither of them is suitable for dealing with the current crisis.

The only thing that can play a role is the "lightning trap".

A lightning trap requires 150 ghost points, which doesn't seem like much, but the problem is that this kind of lightning trap doesn't take effect all the time, judging from the results of Xiao Chen's previous observations, this trap will enter a short "charging period" after almost every time it uses electricity to destroy some ghost creatures, this "charging period" is about 30 seconds.

This also means that using a "lightning trap" to guard a passage can only find death, and multiple traps must be coordinated to defend to survive.

Xiao Chen still had 1,100 ghost points left after learning the last "out of nothing" skill before, plus it was just after 12 midnight now, and the moon spirit as a spirit servant provided him with an additional 200 points, which is a total of 1,300 points.

A full fight is enough to place 8 lightning traps.

Now that Xiao Chen wants to defend two passages at the same time, it should be that four traps should be placed in each passage in turn.

However, even so, Xiao Chen still felt a little uneasy, but now there was no other way to replenish the ghost points.

Xiao Chen decisively put the eight traps on both sides!

"Do you want to let Li Gon come out and help?" Moon Ling asked.

Before Yue Ling finished speaking, Xiao Chen heard Li Gon's shout from the cell not far away: "Xiao Chen! You're not there! I'm dizzy! ”

It wasn't for Yue Ling's reminder and Li Gon's scream, Xiao Chen almost forgot about the people in the cell......

He hurriedly rushed over to open the door of the cell, only to find that Li Gon and the bald head inside had extremely painful expressions, only Huang Mao did not have any abnormalities, and he even immediately made a gesture to Xiao Chen to beg for mercy.

Xiao Chen doesn't have time to talk nonsense with them now, since Huang Mao is fine, then continue to lock him up, and this bald head will not confess, even if he faints, it has nothing to do with him.

Only Li Gon is still worth saving.

Xiao Chen immediately asked Li Gon to find a way to empty the energy in his body.
