It turned out that in this dense fog, Yin Monkey had already taken his classmates who were good at talisman arrays and magic arrays to repair the traps of the magic circle, and at the same time, they laid out monitoring magic weapons in the dark.

These monitoring artifacts are all made by Sumu Improvement and Krypton Shop, and the quality is first-class. And it has been tested in previous actual battles.

Although these demons sent by the Demon Lord are good at stealth, mimicry, change and other demon arts, and they are also cautious along the way, they are still unknowingly, they are hidden in the dense fog by the monitoring magic weapon, and they capture their demonic energy fluctuations.

As a result, the monkeys and classmates in the dense fog received warnings at the first time.

"Teacher Monkey, there are demons and ghosts that have slipped in, are we going to activate the traps and kill them?"

After receiving the news, some students were eager to try to use these demons to test the power of the magic circle and trap they had just repaired.

Yin Monkey also wanted to do this, but he thought about it more, for fear that rash action would startle the snake and ruin his boss's plan and arrangement, so he asked everyone to calm down.

"Don't worry, I'll ask the old ...... Ahem, ask Su Mu. Suspend the operation of the circle and the traps, and don't expose the grass and snakes. Also, they all put on invisibility cloaks to activate the illusion that Lin Junjie brought people to set up before. ”

The students immediately followed their words.

I have to say that the caution of the monkey is very necessary.

These demons sent by the Demon Lord are not only good at lurking and stealth, but also possess natural skills such as [Insight] and [Truth Debate].

Ordinary illusions and changes cannot escape their eyes with [Insight] skills.

And no slight smell can escape their noses, which have the talent of [Truth].

If Yin Monkey and his classmates only relied on tactical cloaks, they were likely to be exposed—either by these demons and ghosts, or by smelling a faint human smell.

But when they use both the Tactical Cloak and the illusion, the chance of being exposed is greatly reduced!

Because in these days, Su Mu has made targeted improvements to a variety of spells according to the Yuanqiao Secret Realm and the situation of the demons here.

There's illusion in that.

After all, along the way, the frequency of everyone using illusions was quite high, and it was naturally listed as a priority for breakthrough and improvement spells by Su Mu.

The illusion that has been improved by Su Mu is more deceptive and realistic, not only can it produce illusions to deceive the eyes, but it can even simulate realistic sounds, smells and touches, deceiving all senses and judgments.

Even if these demons have innate skills such as [Insight] and [Truth Debate], they can still be deceived.

Su Mu did not hide these improved illusions, and in the process of hurrying, he taught them to Pei Jun, Lin Junjie and all the classmates who had studied illusions.

Because Su Mu knew very well that if he wanted to get out of the secret realm of Yuanqiao, it was not enough to rely on the strength of one person alone, and he had to give full play to everyone's strength and maximize it.

At this moment, the demon who entered the dense fog turned on the two skills of [Insight] and [Argument of Truth] at the first time, a trace of red light flashed in his eyes, and his nose even sucked in all the odor factors around him.

However, they found nothing.

At the same time, between the dense fog and the Great Wall of Yinshan, Su Mu, who was building various poisonous arrays, received a report from the monkey.

"The demon has finally sent 'eyes' to the Yin Mountain. I thought they would have arrived earlier, but I didn't expect it to be delayed until now. ”

"Do you want to kill these 'eyes'?" asked Lin Jian'e.

She had already led people to arrange the position of the munitions and magic weapons, and at this moment came to the dense fog and the Great Wall of Yinshan to build a sword formation.

In addition to her and Su Mu, there are some other students who are good at magic circles who are busy here.

After listening to Lin Jian'e's proposal, Su Mu shook his head without hesitation.

"Killing them will make it easy to startle the snake and make the Demon Lord suspicious. We're not done yet, and we'll need to delay a little longer. Tell Lin Junjie and Pei Jun that their stage should come in handy. In addition, inform everyone to pay attention to concealment and don't expose it. ”

The last few words were ordered to Amiya.

After Amiya taught Yin Monkey and the others how to repair the magic circle and traps, and instructed them to master these techniques, she returned to Su Mu's side.

Hearing Su Mu's arrangement at this moment, it immediately responded, "Okay doctor." As soon as possible, the news was conveyed to the rune figures that each student carried, and these rune figures were made to explain them in detail.

After receiving the news, everyone activated the tactical cloak and illusion at the same time, just like the monkey and the others.

The demons who came into the Yin Mountain didn't know anything about these situations.

They cautiously walked through the dense fog all the way, thinking that they were not exposed, but they were 'watched' by the cultivators the whole time.

Out of the thick fog, they saw the Great Wall of Yinshan Mountain and the group of 'cultivators' surrounding the city gate.

Of course, what they see is an illusion, but they don't know it, and they think it's reality.

Because of the two innate skills of [Insight] and [Dialectic], no problems were found.

These demons never imagined that the illusion skills of this group of cultivators had been greatly improved and improved in just a few days, and their talents were extremely targeted, completely deceiving them!

After all, in the demons, there is no coercion, and there is no kryptonite boss......

These demons didn't get too close, they just watched from afar. Because those 'cultivators' at the gate of the city not only arranged for people to be on guard and patrol, but there seemed to be sentry agents in the secret, and the demons and ghosts were afraid that if they got too close, they would be discovered.

The illusions constructed by Pei Jun and Lin Junjie are all from the perspective of reality, and only in this way can the enemy believe that it is true and will not be suspicious.

If the cultivators in the illusion were not well fortified, I am afraid that they would immediately arouse the vigilance of these demons, instead of believing in the scene in front of them as they are now.

Although they didn't get too close, the demons still saw the situation at the city gate very clearly.

They came together, and the voices were discussing:

"Look, these cultivators are really trapped by the unlocking map of the Yinshan City Gate!"

"It's been a while since they arrived in Yinshan, and they haven't deciphered the unlock map yet, which is stupid enough!"

"The Demon Lord said that if the cultivators don't find the unlock map, we have to give them some hints. But how do you give this hint?"

Yes, how to give a hint so that the cultivator can believe it without revealing his own existence?

The demons have a headache for this.

But there is a demon who is well aware of this.

It grinned, "It's easy, look at me!"

At the same time, it is also secretly proud in its heart: Since you can't do it, then don't blame me for being in the limelight! If it is done this time, I will definitely be the first merit, and after following the demon master, I will definitely be more valued, and from then on I will soar and walk to the peak of demon life, hahaha......

Triumphant, but this demon has not forgotten his business.

It spread out its hands, and saw one after another swarthy beetles emerge from its palms, spread their wings, and fly in the direction of the city gate.

These beetles can be seen everywhere in the Yuanqiao Secret Realm, and this demon believes that even if the cultivator discovers them, he will not have any suspicions.

But it has an ability similar to that of a beast-controlled cultivator, which can command a group of insects to do what it wants.

It is precisely because of this special ability that this demon has earned a nickname - the Queen of Blades.

The black beetle quickly reached the gates of the city, and at the behest of the Queen of Blades, flew to the stone monument and the masonry of the city walls, which contained the information.

"Buzz—"

Several black beetles perched on the steles and the masonry of the city walls, flapping their wings and rubbing against each other, making a loud noise.

The cultivators in the illusion immediately reacted.

And the true cultivators who had hidden their figures and were making pre-battle preparations also noticed this scene.

Some students were surprised by this scene: "These demons are actually providing clues to open the city gate? Could it be that they are not enemies, but their own people who have been bought by Teacher Su?"

Su Mu knew very well that these demons were not his own people at all, and quickly guessed their intentions: "The demons want us to open the Yinshan Pass and activate the [Homecoming Gate] as soon as possible." I didn't expect them to be even more anxious than we were. ”

"Then what should we do?" asked a classmate who was not far from Su Mu and was helping to build the magic circle.

The corners of Su Mu's mouth hooked, and he said with a smile: "Since these demons and ghosts have given clues, if you can't open the gate of Yinshan City, it will make the demons suspicious." Anyway, open the door and let them try my new trap!"

Of course, before opening the door, the role that should be played still has to be played to the fullest.

At the gate of the city, the cultivators in the illusion immediately launched an investigation, not only to check the clues, but also to inspect the surrounding situation.

These cultivators who patrol the surroundings are real people rather than illusions, and they are all students majoring in fairy acting, they are professionals, and their acting skills are excellent.

There are also some people who deliberately slipped around a few demons to make them more convinced that what they saw was real and not an illusion.

Soon the gate of Yinshan City was 'opened', and at the same time, the cultivators who had been transformed by the illusion were still cheering, saying that this was: "The spirit of the martyrs in heaven is blessed." ”

These words, of course, were addressed to a few demons.

It's a pity that these demons didn't know that all this was a scam, especially the Queen of Blades, who thought that she was really successful, was very proud, and at the first time, she used special magic to report to the demon lord outside Yin Mountain.

After the city gate was opened, the cultivators who had been transformed by the illusion entered the Yinshan Pass. These demons and ghosts also hurriedly followed under the orders of the Demon Lord.

But just when they just walked under the gate of Yinshan Pass, they collectively paused, and their eyes were confused.

Sumu's trap takes effect, causing them to fall into the labyrinth of illusions!

This trap is similar to Yihui's Phoenix Phantom Demon Fist.

Su Mu glanced at the few demons standing at the gate of the city, and did not take it lightly, but ordered everyone:

"Hurry up and make the final preparations!

Trapping these demons, although it can delay some time, it can't be delayed for too long.

As soon as the demons notice that something is wrong, they will immediately take follow-up action, and we don't have much time!"
