The underground palace is connected to an underground space, wet and cold, full of water ponds and natural black stalactites. This underground space is a huge underground palace built on the basis of a natural crypt. The inner area has three or fifty football fields together, all covered with guards dressed like cans of iron, some hidden rock cracks, or the top of caves, ambushing soldiers hanging upside down like owls.

Three steps, one post, and seven steps and one whistle, the defense layer is solid like an iron bucket, which is almost leak-proof.

There is no light here, five fingers are out of reach, and the sound of neat steps echoes. In addition to the fixed guards, there are mobile patrol teams that roam along the established route to prevent all-round invasion in all directions.

Difficulty of penetration is higher than expected.

Judging from the coordinates, it is five to six kilometers thick from the ground. The air was very cloudy and there was no way to breathe. Zhang Mu has provided a magic potion for the convenience of penetration. It does not need to breathe, does not affect the function of the body, and can be maintained for a long time.

"There are so many guards!"

Zhang Mu went to the front, all wearing black impenetrable armor, like the guards of an underground palace like cans of iron, each with strong fighting ability. Zhang Mu's strength can deal with more than a hundred, and if it reaches two hundred, it will be difficult. The guards here conservatively estimate that there are one or two thousand.

"Since this step has been reached, there is no reason to return to the same way." Zhang Mu was holding against the wall of the palace, holding his breath and thinking about the countermeasures. After a moment, he had an idea, "take a risk, let's not expose it, check this. .Now even after leaving the Devil's Sea and returning to Zhonghai City, there is no sin. It is expected that the alliance will not treat me afterwards. "

Zhang Mu has done everything he can.

At least worthy of the commander's alliance position.

Now it's a dilemma.

Zhang Mu intends to take another risk and leave the retreat, regardless of success. Joe Sebey, interim minister of the special warfare department, led a small team of special operations forces, Bare, commander of the West Seas embargo, and led up to 20,000 embargoed soldiers. Once this force reaches the imperial city, no matter what the demon emperor engages in, it must Can beat him up!

Zhang Muyou [Blessing of the Gods] saved his life. Even if exposed during the infiltration process, he can gain invincibility for a few seconds by casting his skills. At that time, the teleportation scroll should escape and there must be no problem. Although the semi-sacred is very powerful, it can't break the invincible state.

"Covering the magic of heaven!"

Zhang Mu's power moved to the extreme, the thick black mist was released, and it gradually diffused. The concentration of these mists is very high, and the energy contained in them is even more amazing. Zhang Mu played fourteen chaos inscriptions in succession, melted into a dense fog, and the chaos power penetrated into the fog, which caused a qualitative transformation of the energy covering the magic of heaven.

"Transformation!"

Zhang Mu used thoughts to control the nature of the fog, and finally formed fourteen human figures, all of which turned into canned guards. Zhang Mu covered the body with a fog covering the sky, posing as a guard. In fact, Zhang Mu's plan is very simple, disguised as an underground palace guard patrol, so that he can mix in.

Of course, going straight will definitely be seen through. Zhang Mu must create some confusion, disrupt the order of the palace guards, and then take the opportunity to mix in.

Zhang Mu kept a move beforehand, recorded the current coordinates and sent them to Leng Yun and Qiao Weier. The reinforcements will soon arrive at the Devil's Sea. Once the infiltration plan fails and Zhang Mu is forced to flee, when the army arrives, they will be forced to strike directly and break in with violence.

No worries.

Zhang Mu took out the swallowing bag.

In the deep and horrible underground palace, there were ten undead kings and dozens of undead souls, each of which was ghostly, with green fire burning in his eyes. Zhang Mu shoved some of the advanced magic scrolls in the storage bag into the hands of a few wise undead, and then took a dozen phantoms of the palace guard, hiding in a corner of the maze, and started counting time.

Zhang Mu probably figured out the law of the patrol guards in the underground palace. When several major patrol teams are relatively far away and scattered, it is the best time for the undead to launch an attack.

10 minutes left.

5 minutes left.

2 minutes left.

...

Zhang Muzheng calculated the time with his watch, and finally it was time.

attack!

Zhang Mu issued an order, and this great undead roared, jumped out from several directions of the maze, and rushed into the crypt space. Six or seven magic scrolls were directly excited and thrown out. Thunder, flames, and frost. The palace guards were struck by strong magic, and a large area of ​​casualties was instantaneously. The crypts shook violently, and a large number of stones hit the ground.

spread!

Zhang Mu issued another order.

Every two undead kings are a group, each carrying eight or nine undead, and launching attacks from different directions.

"Where's the undead!"

The underground palace guards were blown up by the magic scrolls. The undead would not give the underground palace guards time to think about it. The undead king directly rushed up, all of them exerted their strongest attack skills, destroying the rotten version and repelled several underground palace guards.

"An enemy attack!"

"An enemy attack!"

"Come here to help!"

The guard in the crypt shouted.

Here comes the opportunity!

Zhang Mu took the opportunity to break into the underground world with a dozen phantoms. These undead fighting powers are quite strong. After all, there are ten undead kings in it. The undead killed in the crypt and spread out in different areas. They run in different directions. The underground palace guards can only chase the world and catch which one to kill.

This created an opportunity for Zhang Mu. He led a dozen phantoms, pretending to chase the undead, and rushed straight towards the central area. On the way, a new undead was released with a swallowing sky bag to attract the attention of the underground palace guards.

The entire underground world has become chaotic.

There were shouts from all sides.

"Hey, say you guys, which ministry are you out of bounds!"

A large number of underground palace guards formed a human wall, blocking the front and alerting vigilantly. When they saw Zhang Mu rushing, they immediately blocked the way. Similarly, the palace guards, different teams have different areas of activity, it is strictly prohibited to cross each other.

A person who looked like the captain stood up and scolded, "Which team do you belong to, what's your name, report it immediately! Otherwise, you're welcome!"

"There are undeads! Kill the undeads!"

Zhang Mu secretly opened the swallowing bag, and another undead king jumped out. This is a very strong undead king, about half of Tianling's strength, and a warrior.

"Look! The undead appears!" Zhang Mu pretended to cut, and the undead king jumped away, dragged a large knife, and rushed into the guard of the palace. Zhang Mu screamed, "Be careful!"

The Undead King acted very sharply, and a captain of the guard just came out to speak and was split in half on the spot. The Undead King slashed to the right, chopped down three or five Earth Palace guards, and then kicked his feet into the core area.

"Kill them!"

Zhang Mu shouted loudly.

"Kill them!"

The underground guards forgot to stop, and picked up their weapons to hunt down the undead king.

These underground palace guards are very powerful, but the mission of the undead king is not fighting, mainly to delay time and create chaos. Under the deliberate control of Zhang Mu, he did not confront the underground palace guards, jumped up and down, and ran around just to stir the water Let Zhang Mu's muddy water touch the fish.

Zhang Mu himself did not expect that this bold and adventurous plan was really effective, taking advantage of the confusion in the guards of the palace. Zhang Mu successfully came to the central part, in order not to cause too much attention, removed several phantoms, from 14 to 4, reducing the target. With so many undead attacks, it was normal for a patrol squad to kill some people.

A huge black pillar appeared in front of it!

Zhang Mu can see at a glance that the pillars are not formed naturally, or even made of any common material, but are cast from a special magic metal, like a giant reactor of a nuclear power plant, painted with bright red ink containing powerful magical energy. Thousands of magic runes.

Inside the black pillars, there is a very strong evil energy.

Zhang Mu stepped closer. The pillar stood in the middle of the crypt. The pillar is a circle with a radius of 500 meters. It is a huge black magic formation. Zhang Mu has never seen such a strong magic formation. Just looking at it, you can feel it. Then, the magical energy in the magic circle was released.

"Gather all!"

The voice of an indifferent hoarse old man spread throughout the time, because of Zhang Mu's relationship, the guards in the palace that made the chickens fly and jumped were all moved closer to the middle. After a while, Zhang Mu was surrounded by cans of iron, about 20,000 or so, and the black giant pillars were surrounded tightly. The guard clenched his weapon nervously and waited for fear of being attacked again.

Zhang Mu was in the crowd, and no one noticed him.

"It must be the investigation of the West Sea that made Zhang Mu's ghost!"

This is a familiar voice-Dark Lin.

Dark Lin, wearing a purple robe, stood on the edge of the magic circle, raised her head and looked at the black giant living on top. There was a figure sitting there, not very tall, about one meter six, full of long silver-white hair, all the way to the waist, wearing gray coarse leather clothes, because he was facing away, so he could not see his appearance.

Dark Lin continued: "If this person comes in, we will be in trouble!"

The demon emperor sat on the huge black pillar without turning back, and said lightly, "Dark Lin, you're staying well, don't worry about it?"

Anlin was a little annoyed: "This matter is very important. How could I be a traitor to the Alliance if it wasn't for you ?!"

The demon emperor floated up, suspended in the air, and slowly turned around. Compared with the messy demon, the demon emperor looks very close to the human aesthetics. It ’s not so good-looking, at least it has a human-like appearance, purple skin, smooth like eggs, thin and long ears, no white eyes, completely dark pupils, like a bottomless abyss, long silver-white hair, Each hair is neat and tidy, with a smile on it and a little sense of elegance, but has more of a big devil's temperament than Dark Lin.

Semi-Holy.

Zhang Mu's heart hung up.

Dark Lin didn't want to argue with the Demon Emperor, "The investigation officer of the West Sea is likely to have infiltrated it, aren't you afraid of planning to be known by the Green Alliance?"

"Is the investigation done by the West Sea? I know, of course I know ..." The demon emperor floated in the air, showing a wicked smile, "Isn't he just here?"

Dark Lin stunned: "What!"

Zhang Mu felt the eyes of the Demon Emperor come over.

At this moment, he had a feeling of entering the ice cave!

The demon emperor stared at Zhang Mu and said leisurely: "Humans, you look down on me too much. From the moment you stepped into the demon city, I started to pay attention to you. Welcome, Zhang Mu, commander of the Xihai Investigation!

Damn it!

Can't hide it!

God bless!

Zhang Mu released colorful rays of light, and the demons around him stunned away. A golden scroll was held in his hand, ready to be activated.

"Hehe, you come in with all your thoughts. Why not sit down and have a drink and talk about it? Why bother!"

The demon emperor moved his finger gently.

The space seemed to be poured into cement and solidified.

Teleport Scroll cannot be fired.

No response at all!

"The power that disrupts space ..." Zhang Mu gradually faded from his body, widening his eyes, revealing an unbelievable color, "You ... are not semi-holy at all, you are already the Holy Spirit!"

Not Zhang Mu's intention!

Just didn't expect that intelligence was wrong ... a very fatal mistake!
