The underground palace is connected to an underground space, damp and cold, full of pools, and natural black stalactites, this underground space is a huge underground palace recreated on the basis of a natural crypt. The inner area was the size of thirty or fifty football fields combined, and was littered with guards dressed like tin cans, some hidden rock crevices, or the top of the caves, where warriors hung upside down like owls.

Three steps and one post, seven steps and one sentry, the defense layer is as solid as an iron bucket, which is simply not leaky.

There is no light here, you can't see your fingers, and there are bursts of neat steps, in addition to the immobile guards, there are also mobile patrol teams, wandering according to the established route, defending against foreign invasions in all directions.

The difficulty of penetration is higher than expected.

Judging by the coordinates, it is five or six kilometers thick from the ground. The air was so turbid that there was no way to breathe. In order to facilitate infiltration, Zhang Mu has long prepared a magic potion, which does not require breathing, does not affect body functions, and can be maintained for a long time.

"There are so many guards!"

Zhang Mu walked over, and in front of him were all wearing impermeable black armor, like dungeon guards like iron cans, each of whom had strong combat capabilities. Zhang Mu's strength is a lot to deal with more than 100 people, if it reaches 200, it will be difficult, and the guards here are conservatively estimated to have 10,000 or 20,000.

"Since we have come this far, there is no reason to go back the way we came." Zhang Mu leaned against the wall of the dungeon, holding his breath and contemplating, thinking about countermeasures, and after a while, he had an idea, "Take a risk, it's a big deal to be exposed, and find out about this." Even if I leave the Devil's Sea and return to Zhonghai City now, there is no sin, and I don't think the alliance will treat me badly afterwards. ”

Zhang Mu has reached the point where he is now, and he has done his best.

At the very least, he is worthy of the position of commander of the alliance.

Now we have reached the point of a dilemma.

Zhang Mu planned to take another risk, whether he succeeded or not, he had to leave and retreat. Qiao Saibei, the interim minister of the Ministry of Special Operations, led a small team of special operations troops, Barre, the commander of the Xihai Forbidden Army, led up to 20,000 forbidden soldiers, once this force of Liliang arrived in the Demon Emperor City, no matter what the Demon Emperor did, he would definitely be able to beat him to pieces!

Zhang Mu has [Heavenly God's Blessing] to save his life, even if he is exposed during the infiltration process, he can gain a few seconds of invincibility by using his skills, and at that time, it must be no problem to stimulate the teleportation scroll to escape. Although the Demi-Saint is very powerful, it cannot break the invincible state.

"Heaven Covering Demon Skill!"

Zhang Mu liliang ran to the extreme, and the thick black mist was released, which slowly spread. The concentration of these fogs is very high, and the energy contained in them is even more amazing. Zhang Mu punched out fourteen chaos inscriptions in a row, each of which merged into a dense fog, and the chaos liliang penetrated into the fog, causing the energy of the Heaven Covering Demon Skill to undergo a qualitative transformation.

"Transfiguration!"

Zhang Mu used his mind to control the nature of the mist, zuihou pinched into fourteen human shapes, all of which turned into the shape of a tin can guard, and Zhang Mu covered his body with a fog that covered the sky, disguised as a guard. In fact, Zhang Mu's Jihua is very simple, disguised as a dungeon guard patrol, so that he can blend in.

Of course, you will definitely be recognized. Zhang Mu must create some chaos to disrupt the order of the palace guards, and then take the opportunity to sneak in.

Zhang Mu left a move in advance, recorded the current coordinates and sent them to Leng Yun and Qiao Weier. The reinforcements are about to arrive in the Devil's Sea, and once the infiltration of Jihua fails, Zhang Mu is forced to flee, when the army arrives, it will be directly forcible to attack and break in with violence.

No worries.

Zhang Mu took out the swallowing bag.

In the deep and terrifying underground palace, there were ten undead kings and dozens of earth spirit undead, each of them ghostly, with green fire burning in their eyes. Zhang Mu stuffed some high-grade magic scrolls in the storage bag into the hands of several wise undead, and then took a dozen dungeon guard phantoms, hid in a corner of the labyrinth, and began to calculate the time.

Zhang Mu probably figured out the rules of the dungeon patrol guards, when several main patrol teams were relatively far away and scattered, it was the best time for the undead to attack.

There are 10 minutes left.

There are 5 minutes left.

There are 2 minutes left.

……

Zhang Mu pinched the watch to calculate the time, and finally the time was up.

Attack!

Zhang Mu gave an order, and the great undead roared, jumped out from several directions of the maze at the same time, and rushed into the crypt space. Six or seven magic scrolls were directly stimulated and thrown, thunder, flames, frost, and the dungeon guards were hit by strong magic, instantly casualty a large number of casualties, the crypt shook violently, and a large number of stones fell to the ground.

Disperse!

Zhang Mu issued another order.

Every two undead kings are in a group, each with eight or nine undead, and attack from different directions.

"Where did the undead come from!"

The dungeon guards were blown up by the magic scroll, and the undead would not give the dungeon guards time to think, so the undead king pounced directly, and all of them used their strongest attack skills, destroying the withered and decaying version to repel several dungeon guards, and rushed in five or six directions.

"Enemy attack!"

"There's an enemy attack!"

"Someone helped!"

The guards in the crypt shouted.

Here's your chance!

Zhang Mu took the opportunity to take more than a dozen phantoms and broke into the underground with a big grin. The combat effectiveness of these undead is quite strong, after all, there are ten undead kings in it, and the undead are killed in different areas and scattered, running in different directions, and the dungeon guards can only chase with shijie, and kill which one to catch.

This created an opportunity for Zhang Mu to take advantage of, and he led a dozen phantoms, pretending to chase after the undead, and rushed straight towards the central area. On the way, he used the Sky Swallowing Bag to release new undead spirits to attract the attention of the dungeon guards.

The entire underground shijie became chaotic.

There were shouts of killing in all directions.

"Hey, what about you, which department, you crossed the line!"

A large number of dungeon guards formed a human wall, blocking the front, vigilantly on guard. When he saw Zhang Mu rushing over, he immediately blocked the way, the same palace guards, different teams have different activity areas, and it is strictly forbidden to cross the line with each other.

A man who looked like a captain stood up and scolded: "Which unit and team are you from, what is your name, report your name immediately!" You're welcome otherwise! ”

"There are undead! Kill the undead! ”

As Zhang Mu spoke, he secretly opened the Sky Swallowing Bag, and another Undead King jumped out. This is a fairly strong undead king, about the middle strength of the Heavenly Spirit, and he is a warrior.

"Look! The undead have appeared! Zhang Mu pretended to cut it, but the Undead King jumped away, dragged a big knife, and rushed into the palace guards, Zhang Mu hurriedly shouted: "Be careful!" ”

The undead king's movements were very neat, and the captain of the guard, who had just stood up and spoke, was split in half on the spot. The Undead King slashed horizontally, knocking down three or five dungeon guards in a row, and then kicked his feet and broke into the core area.

"Kill them!"

Zhang Mu shouted.

"Kill them!"

The dungeon guards forgot to stop it, and grabbed their weapons to chase down the undead king.

These dungeon guards are very strong, but the task of the undead king is not to fight, the main thing is to delay time and create chaos, Zhang Mu deliberately controlled, did not fight with the dungeon guards, jumped up and down, ran around, just to muddy the water, let Zhang Mu fish in troubled water.

Zhang Mu himself didn't expect that this bold and adventurous Jihua would really be effective, taking advantage of the chaos of the palace guards. Zhang Mu successfully came to the central part, and in order not to attract too much attention, he removed several phantoms, from 14 to 4, and reduced the target. So many undead attacks, a patrol squad, and some people being killed, it's normal.

A huge black pillar appeared in front of it!

Zhang Mu could see at a glance that the pillars were not naturally formed, or even made of any common materials, but were cast from a special magical metal, like the giant reactor of a nuclear power plant, and thousands of magic runes were carved with bright red pen and ink containing powerful magical energy.

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

Zhang Mu walked a little closer, the pillar stood in the middle of the crypt, the pillar was the center of the circle, with a radius of five hundred meters, it was a huge black magic array, Zhang Mu had never seen such a strong magic array, just by looking at it, he could feel that the magic array released an earth-shattering powerful energy.

"All assembled!"

An indifferent and hoarse old man's voice spread throughout the time, and because of Zhang Mu's relationship, the guards of the underground palace who made chickens and dogs jump all moved closer to the middle. After a while, Zhang Mu was surrounded by iron cans, about 10,000 or 20,000, and the black giant pillar was tightly surrounded. The guards tightened their grip on their weapons and stood ready for fear of another attack.

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

"It must be the Xihai investigation that makes Zhang Mu play tricks!"

It's a familiar voice—Darklin.

Darklin stood on the edge of the magic circle in purple robes, looking up at the top of the black giant residence. There was a figure sitting on it, not tall, about one meter six, with long silver-white hair, draped all the way to the waist, wearing gray coarse leather clothes, because his back was facing away, so he couldn't see his appearance clearly.

Darklin continued, "If this person sneaks in, we're in big trouble! ”

The Demon Emperor sat on the huge black pillar, did not look back, and said lightly: "Dark Lin, you stay well, don't be nosy?" ”

Dark Lin was a little annoyed: "This matter is very important, if it weren't for helping you, how could I become a traitor to the Alliance?!" ”

The Demon Emperor floated up, levitated into the air, and slowly turned around, compared to the messy looking demon, the Demon Emperor's appearance was very close to the aesthetic concept of the human race. It's not very good-looking, at least there is a humanoid, purple skin, smooth like eggs, thin and long ears, no whites of the eyes, completely black pupils, like a bottomless abyss, with long silver-white hair, quite the momentum of a big devil.

Demi-saint.

Zhang Mu's heart hung in the air.

Dark Lin didn't want to argue with the Demon Emperor about anything, "That Xihai Survey Envoy is very likely to have infiltrated it, aren't you afraid that Jihua will be known by the Green Alliance?" ”

"The West Sea Survey Envoy? I know, of course I do......" The Demon Emperor floated in the air, giving a wicked smile, "Isn't that all he has?" ”

Dark Lin was stunned: "What! ”

Zhang Mu felt the Demon Emperor's gaze sweep over.

At this moment, he had the feeling of being in an ice cave!

The Demon Emperor stared at Zhang Mu and said leisurely: "Human, you underestimate me too much, from the moment I stepped into the Demon Emperor City, I began to pay attention to you. Welcome, Xihai Survey Commander Zhang Mu! ”

Damn it!

I can't hide it anymore!

Blessed by the gods!

Zhang Mu released a colorful glow, and the surrounding demons were all frightened, and a golden scroll was held in his hand, ready to be activated.

"Hehe, you took a lot of effort to come in, weishenme don't sit down for a drink or two and have a good talk? Why rush to go! ”

The Demon Emperor's fingers moved slightly.

The space seems to have been poured into cement and frozen.

Teleportation scrolls cannot be activated.

No response at all!

"Liliang ...... that disrupts the space" The glow on Zhang Mu's body gradually faded, his eyes widened, revealing a look of disbelief, "You...... You are not a half-saint at all, you are already the Holy Spirit! ”

It's not Zhang Mu's carelessness!

It's just that I didn't expect that the intelligence was wrong...... A very fatal mistake!
