In an inconspicuous hut in the city lord's mansion of Heilin City, there is a cave inside. In the huge space, there are array patterns everywhere, and countless array patterns are constantly intertwined, forming various mysterious array patterns.

These formations seem to be extremely complicated, but in the eyes of Gu Fei's avatar, this is also the case, because the avenue is simple, in fact, the simpler the dao pattern, the more powerful.

If one formation pattern can be used to replace countless formation patterns and exert a stronger power, does the formation need to be made so complicated?

This is the difference between master and beginner.

In the eyes of Gu Fei's avatar, Hei Lin City's formation was only a primary formation, which is why there are countless formation patterns in this huge space.

At this moment, Gu Fei's clone turned around in the space of countless formations, and then stood opposite the middle-aged man, looking at him indifferently.

The middle-aged man is not a weak person, because he is the guardian of the formation center of the Black Forest City, he is just a guard, and a guard with good combat power.

He doesn't understand formations.

"Don't bring it yet?"

Gu Fei's clone said calmly.

The face of the middle-aged man became ugly. He actually looked down upon this little guy, but he was so curious that this little guy actually understood the formations. How could this be possible? How old is he, but he is just a little sucker. Guys, is he better than the formation master of Qitianmen who is breaking the formation outside the city?

Speaking of the formation method, in the Wuji world, the name of Qitian Gate is really not small, but it is one of the rare formations sects in the Wuji world.

Could it be that this little guy has won a more powerful line of inheritance?

"Want to bet and lose, why, can't you afford to lose?"

Just when the middle-aged man's mind turned into a mess of porridge, the voice of Gu Fei's clone suddenly spread into his mind. There is a power in this voice, and every pronunciation is like a note. Like a heavy hammer, it hit his soul fiercely.

The middle-aged man was immediately awakened by the sound wave power of Gu Fei's clone.

"what!"

The middle-aged man subconsciously squeezed the halberd in his hand. This was a low-grade Taoist weapon. He actually lost it, and his heart was bleeding.

You know, it took him a lot to get this Taoist artifact!

"Get it!"

Gu Fei's clone directly reached out and grabbed the halberd in the opponent's hand.

The middle-aged man was very unwilling, holding on to the halberd, a murderous aura filled his body, and he actually had a murderous intent on Gu Fei's clone.

In Gu Fei's life, he didn't know how many battles he had gone through. He was especially sensitive to murderous intent. As long as someone had a murderous intent on him, he could sense it immediately.

This has become his instinct.

Although the current Wang Zhan is just a clone of Gu Fei in the Promise World, his clone possesses all the combat experience of Gu Fei.

"Ok?"

Gu Fei's clone is not angry, this guy wants to kill himself?

The middle-aged man's heart trembled, and when he loosened his hand, the spear in his hand was taken away by the opponent.

"Hey!"

The middle-aged man sighed, he still didn't dare to make a move, because he couldn't see the depth of this little guy, and this little guy carried Dongyue Xueer's token.

Dongyue Xueer's token is not so easy to give to others, only those who value and trust Dongyue Xueer will have the opportunity to get the token.

Killing this little guy will have serious consequences.

After all, Dongyue Xue'er is a strong heavenly rank, and the power of the Dongyue imperial family is so powerful that middle-aged people don't dare to contend with it. He can only reluctantly cut love.

"Okay!"

Gu Fei's clone said that he would put away the halberd in his hand. He wanted to give Xuan Heihu, but after thinking about it, if Xuan Heihu carried such a war spear, he would kill him directly. The curse, I don't know how to die.

In the Promise World, killings and treasures often happen.

Gu Fei's clone didn't have time to pay attention to this kind of young person anymore, and strode directly into the formation center, and then sat on a stone seat in the center.

With a wave of his right hand, the entire formation center space directly changed.

The middle-aged man outside and Xuan Heihu couldn't see Gu Fei's clone.

Then, in the dazzling divine light, the phantom of a city appeared, and the entire city was shrouded in countless array patterns, only to see the formation pattern above it bursting into small holes from time to time.

They naturally don't know what happened.

The broken holes in the formation patterns are gradually being repaired.

This formation center actually showed the current situation of the entire Hei Lin City, and that city phantom was naturally Hei Lin City.

And the countless array patterns that enveloped Heilin City were the great formations of the city.

The holes that appeared in the formations of the defense formation were the formations that the Qitianmen formation master outside the city broke when attacking the defense formation.

Although no one is in control of Heilin City's great defense formation, it is still operating, and can independently repair the formation pattern broken by the broken arrow.

At this moment, above the sky outside the east gate of Hei Lin City, a figure sitting in the large formation suddenly opened its eyes, and two cold rays of light rushed out of its eyes.

The man in black was the master of the Qitianmen formation, Master Lin invited by the Tyrant Little King Ba Fei.

And Master Lin is very mysterious, with the hat on his head and his face covered. No one knows whether Master Lin is a man or a woman, because he can't tell at all.

This mysterious Master Lin sensed the great changes in the moat of Hei Lin City.

"what happened?"

Master Lin's heart trembled.

Didn't it mean that the formation mage of Hei Lin City was assassinated by the Tyrant Fei? Who else in this Hei Lin City can control the great defense formation?

In order to break the Heilin City, the Tyrant Little Lord can be said to do everything.

He did everything possible to destroy the great defense formation of Hei Lin City.

The power of the Heilin City defensive formation, which no one controls, was greatly reduced. This gave the Master Lin of Qitianmen an opportunity, but at this time, the Heilin City defensive formation had actually changed.

At this time, the most critical time was reached. As long as one or two formations were broken, he could completely break through the big shield of Heilin City, but now there was an accident.

Master Lin was shocked to find that the repair speed of Hei Lin City's great defense formation had become faster, and the aura of the world around Hei Lin City began to converge on Hei Lin City.

Heilin City's great defense formation is actively gathering the power of heaven and earth.

Compared with the passive speed of gathering the power of heaven and earth, the speed of this Black Lin City's guarding formation actively gathering the power of heaven and earth increased by ten times.

Soon, a huge whirlpool appeared above Hei Lin City.

Countless people who were fighting in the city outside the city looked up to the sky in horror.

Everyone was stunned by this scene in the sky.
