Heaven-defying Upgrade System

"Everyone is ready to follow me in!" Liu Fei said. He had the experience of burrowing the ground two times before. Knowing the dangers hidden in this ground hole, he was extremely cautious.

Everyone was fully armed.

Liu Fei and Nangong Yingjie led the way, while Tang Chengze and Yan Luo were at the end of the line, guarding against the danger that might be encountered later.

"Who!"

As soon as Liu Fei and the others walked out of the passageway, a voice suddenly came, and when they fixed their eyes, they were actually two monks! Moreover, the aura that exudes from these two monks is exactly the aura of the demon cultivators familiar to Liu Fei and the others.

Unexpectedly, there is an army of corpses here!

There is nowhere to look for it!

When the guards at the entrances of the two passages were alert, suddenly, the blood demon wand in Liu Fei's hand flew out. The two soldiers of the corpse demon army were still able to defend themselves in the future. The chest was flickered twice by the blood magic wand, and it was pierced! The blood magic wand returned to Liu Fei's hands again.

"This...what is this place? There is such a big city!" Nangong Yingjie exclaimed involuntarily, standing beside Liu Fei.

Liu Fei and others were shocked at the same time, but saw that this underground city is actually a huge city, with many houses and rows of very neat rows. This is actually an underground city! In the deepest part of the dungeon, a pagoda-shaped building stands tall, and on the top of the pagoda-shaped building, a huge orb glowing with incandescent light shines.

The originally dark underground city shines as bright as day.

"Woo..."

At the same time, a rush of humming sounded, and Liu Fei and the others looked terrified. It sounded like the sound of the defense system here.

In a short while, a few streams of light flashed across the dungeon. Liu Fei and the others saw it, but they saw that it was a group of demon cultivators, about dozens of them, among them there were more than a dozen masters in the earth pill realm, and the rest had reached the peak state of the spirit pill realm.

"What a strong momentum!"

These masters gathered together, and they exuded a strong breath that they had never seen before.

Among them, it seems that a leading figure, took a step forward, stood in front of Liu Fei and others, and said coldly: "A group of people who do not know how to live or die, dare to trespass into the forbidden area of ​​corpse demon, hum, since they are here Don't even think about leaving!"

Facing Liu Fei's team of more than 1,000 people, these people were not afraid at all and rushed toward them directly.

Facing so many powerful men, Liu Fei and others did not show any fear on their faces, but they heard Liu Fei faintly say: "Set up an array!"

The members of the Tianxiao team immediately formed the strongest Nine Palace Sword Formation. Some time ago, after Yan Luo's guidance, each small Nine Palace Sword Formation could form a ninety-nine-eighty-one large Nine Palace Sword Formation. A group of eleven people, a total of nine groups, formed the strongest Nine Palace Sword Formation. The sword formation was unfolded, and a group of dazzling rays of light suddenly appeared in the air, which was condensed by the dazzling sword light.

In an instant, the aura of the strongest Nine Palaces Sword Array was released, crushing the aura of those Demon Clan cultivators.

That group of dazzling rays of light swept high in the sky, and rushed like a stormy wave!

Although the corpse demon army is all masters, and even a dozen people have reached the earth pill level, but they felt great pressure in the face of this sudden sword formation attack.

"The other party is just a group of cultivators who have not reached the fourth level of the spirit pill realm. How can there be such a powerful aura?"

These Mozu cultivators didn't know the true power of the Nine Palaces Sword Formation, and they only felt shocked.

Liu Fei, Nangong Yingjie and others did not take action, standing aside and looking at the many demonic cultivators who were enveloped by the sword formation.

"This formation is simply a miracle!" Chen Guangqing said in surprise. At the moment the formation was displayed, the combined power of each person and even each group was far from as simple as one plus one equals two. How many times. At the same time, Chen Guangqing glanced at Yan Luo.

This mysterious figure can actually enhance the Nine Palaces Sword Formation taught by Liu Fei, which is really amazing!

"Roar!"

A roar sounded, and those demonic cultivators were shocked by the powerful power of the Nine Palaces Sword Array after they came into contact with the Nine Palaces Sword Array. They couldn't help being annoyed. The masters of their Earth Pill realm were not as good as a group of Spirit Pills. !

In a short while, those demonic cultivators were shocked by the power of the Nine Palaces Sword Array and kept retreating. But once the Nine Palaces Sword Array is deployed, few people can avoid it.

Nangong Yingjie and Tang Cheng looked at the members of the Tianxiao team, and nodded with satisfaction. Now the Tianxiao team has undoubtedly become a sharp division.

The demon cultivator on that side opened the demonized form, the body of the metamorphosis was huge, and all the attributes such as the power and speed possessed were also greatly improved in an instant.

Nevertheless, under the Nine Palaces Sword Formation, they have no special magic weapon, and they cannot break the formation of the Nine Palaces Sword Formation. The biting sword light exudes a cold light. As the pace of the battle becomes faster and faster, the power is also getting bigger.

In a short while, thirty or forty people fell under the Nine Palaces Sword Array, and the remaining few masters of the Earth Core Realm with stronger cultivation bases felt the tremendous power of the Nine Palaces Sword Array.

Yan Luo, who was standing next to Liu Fei, smiled, and said: "The sword formation that I can comprehend from the Yanlong Sword Art is really good. Unfortunately, that genius who knows the sword intent is limited by his cultivation level, and his comprehension ability is low. However, after my transformation, this formation has now exerted its full power. The Nine Palace Sword Formation displayed by nearly a thousand players will numb the scalp even if it is a master of the Earth Core Realm."

Liu Fei smiled and said, "Besides, they now have the best talents. Both their comprehension and daily practice are far beyond normal."

Yan Luo said: "Yes, this Nine Luo Tianzheng is worthy of a rare talent in thousands of years. It has even completely changed our blood."

Liu Fei was taken aback for a moment, but he didn't expect Yan Luo to see the characteristics of the Jiuluo Heavenly Sign so quickly. It seems to be able to change a person's bloodline, thereby making people fundamentally undergo earth-shaking changes.

At this time, Nangong Yingjie looked at the corpse demon army in the dungeon that was staring at the battle in the distance. He found that the strength of these corpse demon army was actually very weak, that is to say, there were no real masters.

The remaining Demon Clan cultivators have been holding on for a long time, and under the biting sword light, their abnormally transformed demon bodies were instantly cut to pieces.

Only three or four people fled hurriedly.

Immediately afterwards, two red lights galloped from a distance.
