Lao Bai jumped out and turned into a villain, standing on Ye Feng's shoulder, frowning, too familiar with this murderous aura.

"You are right, this killing aura is too pure, it seems to be coming from underground."

Lao Bai nodded, and said with certainty that the killing aura is an invisible gas. Perhaps too many people will die and it will also produce a killing aura, but many of them have evolved into evil auras, which are extremely difficult to absorb and purify.

In the underground world, who can know what's underneath, Ye Feng just thinks about it. With his current ability, he doesn't have the ability to travel underground. Even if there are treasures underground, he can only sigh and he can't dig up here.

Ye Feng still intends to wait till night to see and listen to what the young man said. Once night comes, here will become a haunted house, and even ghosts will appear.

Ye Feng did not believe what the ghost said, even if it was a ghost that crawled out of hell, Ye Feng was sure to kill it.

The sky gradually darkened. Ye Feng stood in the yard, looking at the starry sky, and found that the yard was constructed very strangely. The moonlight could pass through the courtyard in the middle to illuminate the four sides of the yard, forming a strange pattern.

Four different patterns appeared, very weird, like monsters, ghosts and snakes, holding knives and forks to kill people.

"Could it be that this is the legendary midnight bell, and the ghost in the middle of the night kills?"

Ye Feng was very curious. If he hadn't been strong enough to see these four weird shadows, he would definitely be frightened.

The more this happened, the more curious Ye Feng was, and he had to figure out what was in the house.

The night became deeper and deeper, and the murderous aura around them gradually became stronger, forming a thick scarlet aura, supporting the four evil charms is even more weird.

And their shadows began to move, and they felt Ye Feng's breath. Four ghostly shadows suddenly appeared around Ye Feng, holding a knife and fork and began to attack Ye Feng.

"laugh!"

Ye Feng dodged, and a mark appeared on the ground. These attacks were real, not fantasy, which surprised Ye Feng.

No wonder this is a murderous house. As long as you live in this house, you must be killed by these four ghosts, so anyone who buys it will sell the house within a few days.

Ye Feng regrets a bit, so he should continue to bargain, estimated to give him 2 million, this house will be sold to himself, otherwise it will remain in his hands.

The body kept evading, the four ghosts seemed to be very regular, turned out to be a formation form, no matter how Ye Feng dodges, the shadow can always follow.

Ye Feng's speed was getting faster and faster, playing hide-and-seek with ghosts in the yard. As long as there is no moonlight, the shadow cannot go deep and disappear automatically.

As soon as the moonlight appeared, the shadow also appeared, which was extremely strange.

"Lao Bai, see if some doorways have come out!"

Ye Feng fought a cup of tea with Guimei, but from his memory, he couldn't find any information about these four shadows.

Mu Bai was still thinking, seeming to think of something, but he was not sure.

"There may be a ghost killing array beneath this ground!"

Mu Bai said in an uncertain tone that the Ghost Killing Array was very popular back then. When building houses, many people would build such an array underground. The first is to drive away evil and avoid evil. Once someone rushes into the building, Will be attacked by the ghost killing array.

The second is that this ghost killing array can absorb the essence of the sun and the moon and spread it throughout the courtyard. But the ghost killing array here is not like that. It is estimated that the array has been destroyed and has become a pure killing array.

"What kind of formation is this?"

Ye Feng was confused, he was considered a master of formation, but he had never heard of such a thing as ghost killing formation.

"This kind of formation has long been lost. The ordinary formation is built on the ground. Only this ghost killing formation must be built underground, connected to the Nine Nether world, absorbing the spirit of the ghost domain, and maintaining the operation of the formation. "

Mu Bai explained that this ghost killing formation has been lost for many years, and few people will arrange it.

"Then how do we break the formation?"

You can't buy a house and can't live in it. If anyone accidentally stepped into the yard at night, wouldn't he be killed by the four evil spirits?

"Why break the formation? This is a natural barrier. If it is modified, even if the fairyland comes, there will be no return."

Mu Bai did not suggest that Ye Feng remove the ghost killing formation, but was transforming the formation to amplify its power. As long as you be careful at night, this formation can protect the house and practice martial arts, which is a good thing with two birds with one stone.

"You are right, but I don't know anything about Ghost Killing Array, how to transform it."

Ye Feng didn't think about this problem. With his current view of the formation, he couldn't reform the ghost killing formation.

"That's your business, you can find some books about ghost killing array to see if you can find some clues."

Mu Bai spread his hands, he couldn't help this matter, and Ye Feng had to do it himself.

After fighting against the four evil charms, Ye Feng felt that his martial skills had improved a lot, and this was indeed a treasure.

Hidden in the dark, the four ghosts and demons returned to their original places, as if they were evil spirits. If they suddenly appeared at night, they would be scared to death.

"Lao Bai, how deep the ghost killing array is underground, is there something like killing as the center of the formation to guide the operation of the formation."

When Ye Feng was resting, he found the general outline of the formation and began to organize it. Any formation has a center, and this ghost killing formation should be the same.

"Of course, it is not so easy to find a material that can sustain the ghost killing array. It must have a strong will to kill, and it can also introduce Yin Qi to resonate between the sun and the moon, so that the moonlight can be absorbed on the ground and cycle through the formation. These four ghosts were formed."

Mu Bai still knew the news. As for what material it was, Mu Bai didn't know, maybe there was such a piece hidden in the ground.

"If you ask how deep the formation is from the ground, I don't know this, at least it's a thousand feet."

Mu Bai shook his head. He didn't know where the formation was. He just guessed a number.

"A thousand feet!"

Ye Feng shook his head. It is estimated that the fairyland can't reach a distance of thousands of meters, only the fairy king can.

"I already have some clues. Tomorrow I will prepare some materials and arrange a Juyang Formation to complement the Ghost Killing Formation. This should be able to restrain the Ghost Killing Formation."

Ye Feng deserves to be a master of the formation, since he can't crack the ghost killing formation, use it.

Use the Juyang Array to limit the Ghost Killing Array. If there is an invasion by foreign enemies, turn off the Juyang Array and turn on the Ghost Killing Array, which will naturally achieve the purpose of attack.

As soon as the sky dawned, the four ghosts and charms in the yard disappeared automatically, everything returned to normal, and even the murderous aura in the yard dissipated a lot. It is probably because of the daytime that the Yin Qi gradually disappeared.

Stepping out of the yard, closing the ban, Ye Feng rushed to Su Cheng, bought some materials, called Jiang Fei, and came back to set up the formation.

Stepping into Sioux City and hurried to the inn, Jiang Fei must have waited anxiously if he didn't go back overnight, thinking something happened to him.

As soon as I stepped into the inn, there was a loud noise, and it seemed that someone was arguing.

"Boy, quickly kneel down and kowtow to me. Let's forget what happened to me just now."

In the inn, a group of people surrounded them, and they were so arrogant that they wanted people to kneel down.

"I didn't hurt you, you took the initiative to hit me."

Someone was arguing fiercely, and it was obvious that they were cheated, so I was very excited.

"Boy, dare to quibble, believe it or not, we will rectify you on the spot right now, you know whose territory this is."

The scolding voice appeared again, and people watching the excitement in the distance avoided one after another, unwilling to be troublesome.

"Hey, the imperial sect is getting more and more arrogant. From now on, this Su City will never find a clean place."

Someone sighed and left the inn. It turned out that these people belonged to the imperial sect.

Ye Feng stepped into the inn and saw three young people surrounded by one person, constantly berating. The surrounded man, with blood still on his mouth, seemed to have been attacked by the three.

"I didn't bump into you. It was you who deliberately framed me. Do you really think that the Imperial Sect is great? Not everyone is afraid of you."

Jiang Fei wiped the blood from the corner of his mouth and was irritated to his nerves. He just went downstairs and suddenly someone ran into him. Then the three of them leaned on him, saying that he had injured his companion and wanted to claim 5 million immortal crystals.

"You mean we deliberately blamed you?"

The three of them smirked. They did this many times. After repeated trials, they saw that Jiang Fei was a new face.

"Yes, you hit me on purpose."

Jiang Fei fought hard according to reason, and from time to time he coughed violently and suffered a lot of injuries.

"Since you don't know how to promote, don't blame us for being rude!"

The three of them showed their fangs, ready to take a shot. With Jiang Fei's power alone, they weren't the opponents of the three at all.

"Succumb to death!"

As soon as the voice fell, one of them shot first, and the giant palm slapped Jiang Fei. In addition, Jiang Fei was already injured and couldn't avoid it.

Almost all the people in the inn were gone, no one wanted to stay, and they all predicted Jiang Fei's fate and must have died in the hands of three people.

The other two sneered, as if they had seen Jiang Fei being beaten up. Even if they didn't get 5 million Immortal Crystals, killing Jiang Fei should have a lot of resources.

After the imperial sect lost the game with the Dragon Talisman a few months ago, the resources of the entire sect were very tight. They used to receive very generous rewards every month, but now they are constantly deducting it, and they cannot maintain their cultivation at all.

In desperation, the disciples of the imperial sect began to do such a deed, forcibly plundering and depriving those disciples who were inferior to themselves.

Losing five first-level mineral veins is a big blow to the imperial sect, and it is also helpless to reduce expenses.

Not to mention these ordinary disciples, even the saints are the same, and their resources have shrunk by half.

In the past few months, the imperial sect has become more and more frantic, and has no intention of converging. It has been intensified to obtain resources from other people to maintain cultivation.

Seeing the giant palm getting closer and closer, Jiang Fei's eyes showed fierce expression, enduring the injury, he also waved a palm.

"boom!"

The palms were facing each other, and then a figure flew upside down, spitting out a mouthful of blood in the void.
