The desolate prairie stretches as far as the eye can see.

Although it was noon, the sky was strangely dark.

When he saw the large expanse of clouds hanging overhead, Xia Gui also looked up at the sky with some surprise. It's very strange that there are dark clouds all over my head, and the sky is gloomy, while in other places, the sky is clear and the clouds are light.

The nest of the Sky Swallowing Python is not on top of these three extinct volcanoes. Because, this piebald snake dragging a dead knot actually took him to crawl in the direction of the northern base.

Xia Gui felt a little bottomless in his heart, in case a few frenzied murderers suddenly rushed out of the northern base and wanted to arrest him for experiments, it would be troublesome.

There was a little more trepidation in his heart, and it was not good to be out of the organization.

Thinking of this, Xia Gui kept an eye on it, he ghostly lit the communication bamboo cannon in his arms, only to hear the sound of "Tong", the subtle sparks rushed into the sky, exploded when they reached the peak, and then dissipated into nothingness.

To be honest, he was depressed after releasing this communication bamboo cannon, because this bamboo cannon is not gorgeous, and there is no loud noise, and it is gone, I don't know if the teammates in the distance can see it.

If no one receives this signal, he is finished.

"One way to the dark. Xia Gui gritted his teeth and continued to follow the spotted snake.

A man and a snake traveled more than thirty miles on the vast grassland, the sun in front of them became darker and darker, and the dark clouds overhead became extremely thick, as if they were crowded with water and would be pressed down at any time.

At this moment, Xia Gui vaguely saw a huge chaotic stone formation appear.

At first glance, there are hundreds of huge stones standing on the barren meadows. Each stone is of different height, but on average it is tens of meters high, like a huge stone giant looking up at the desolate sky.

Xia Gui couldn't help but take a breath of cold air, these boulders surrounded the wasteland one by one, and each area turned out to be like an island. A kind of simple and mysterious power of the beginning of heaven and earth is revealed from this huge stone formation.

Looking through this group of chaotic stone formations, Xia Gui saw a huge patio made of stone walls, scattered in the chaotic stone formation, looking up at the sky alone.

From a distance, there were about nine stone wells, scattered in the boulder array, and a strange and thick smell of blood wafted from this stone well.

Before he got closer, Xia Gui had already covered his nose in disgust, and the smell made his stomach tumble.

At this moment, the spotted snake, which was limping and crawling, suddenly flashed a glimmer of brilliance in its eyes, and arched towards the Stonehenge in front of it at a noticeably faster speed.

This guy is so excited, could it be that he has met his master?

Xia Gui was suspicious in his heart, and sure enough, he heard Budan say: "The Sky Swallowing Python is in this area, don't let it report the news!"

Before Boudin finished speaking, Xia Gui's figure jumped like a black shadow, and the palm wind had already fallen.

With a "snap", this spotted snake with bad intentions and an attempt to report the news finally died in Xia Gui's fierce palm.

After shooting the spotted snake to death, Xia Gui hurriedly lowered his body and hid behind a big rock, his eyes kept looking around, and his heart was also pounding.

"Where is the Sky Swallowing Python?" Xia Gui was shocked.

"Haven't shown up yet. Boudin replied.

"Did it find me?" Xia Gui asked again.

Boudin said: "Don't worry, if it found you, it would have swallowed you in one bite!"

Xia Gui breathed a sigh of relief and hid behind the big stone and didn't dare to come out. Although he hadn't seen the shadow of the Sky Swallowing Python yet, he had already felt the strangeness of this place.

It was daytime, but the sky was as gloomy as the end of the world, and it was terriblely dark.

"Hehe, the sky-high resentment from the northern base turned out to come from here. Boudin suddenly smiled quietly.

This smile made Xia Gui's scalp tingle, and he hurriedly hid behind the stones.

This place is indeed strange and terrifying.

There was also a huge stone formation, which seemed to be an extremely terrifying formation, and countless revenant spirits were rushing out of the nine patios, and the nine scattered patios exuded a strong and disgusting smell of blood.

Looking at the nine deep and eerie patios, Boudin fell into deep thought, as if he was feeling some fluctuations.

Yes, an extremely powerful power fluctuation, accompanied by a surge of hatred!

Boudin's tightly knit brows suddenly stretched, and then he sneered: "The old man finally understands, hehe, it's really a great masterpiece." The lackeys of Jiuhou Villa actually deployed an ancient forbidden formation here!"

Ancient Forbidden Formation?

Xia Gui was stunned, and then a chill traveled along the pores, quickly covering the whole body.

The formation is also divided into three, six, nine and so on, like Xia Gui's current cultivation is the first-order and second-order formations, with the improvement of soul power and technical strength, he will come into contact with the sixth-order, seventh-order advanced formations, and even the eighth-order and ninth-order top formations.

Some formations are very powerful, but this kind of formation is too powerful to control, or too vicious, or maybe because the means of refining the formation are too cruel, it is forbidden for people to use, so it is called "forbidden formation".

Because the impact of this forbidden array on human beings is too huge and the methods are too cruel, anyone who is found to be secretly refining the forbidden array will be punished by various countries. Therefore, by now, no one dared to refine the forbidden array in public. Some spirit array masters can't resist the temptation of the powerful power of the forbidden array, and secretly refine it, but as long as they are discovered, they will be hunted down by people from all walks of life.

Xia Gui's eyes circled around the nine bloody and resentful patios, and the terrifying emotions became more and more profound.

The Ancient Forbidden Array, there is no need to say much about what this means. It's more terrifying than an ordinary forbidden formation. They are often exquisite formations left over from ancient times, at least above the sixth order. Then the power that erupts from it has the power to destroy the world and destroy the earth. It's also even more terrifying.

What's more, it's the Ancient Forbidden Array?

This means that this formation is not only powerful, but also extremely cruel and terrifying. The nine patios that smelled of blood and the boulders that had been carried out of nowhere, all exuded strange, ancient, and evil powers. This is a well-deserved Ancient Forbidden Array.

"Are these people from Jiuhou Villa tired of being alive, and they dare to refine the Ancient Forbidden Array!" Xia Gui frowned.

"This is the territory of the Ghost Fang Kingdom, and the Ghost Marquis is the great prince of the present, as long as the Shang Emperor Xin is not angry, who would dare to oppose them? Besides, they are also secretly refined, and no one knows. Boudin said.

Xia Gui looked at this terrible patio, and a hint of depth flashed in his eyes.

"No wonder the slaves of the Nine Marquis Villas were never directly executed after committing capital crimes. I finally know where those slaves have gone......" Boudin sneered.

Xia Gui said in a low voice: "Thrown into this patio?"

Boudan snorted coldly, "First it was transported to the base for experiments, and after the experiments were completed, they were thrown into this patio to refine the formation. This ancient forbidden array requires a large amount of flesh and blood, so whether it is a surviving slave or a broken arm and stump, as long as it is human flesh and blood, it can be thrown into this patio to refine the formation. ”

Boudin squinted his eyes and looked at the nine patios, and his tone was extremely cold, "So, these nine deep and large patios should be mixed with the flesh and blood of thousands of slaves...... And this evil formation is called 'Blood Demon Grudge'. Only with enough flesh and resentment can the true blood demon be refined. ”
