As soon as he entered the stone gate, the old man in the animal skin shot out a spiritual power towards the array plate in his hand with one hand, and suddenly, the two huge stone doors that were open closed in a roar, and various array runes resurfaced, flashing with spiritual light.

Seeing this scene, Jia Zhenjing, the old woman and others were all shocked, and couldn't help but glance at each other, and a different color appeared in their eyes.

"Don't worry, although this stone door is difficult to open from the outside, it is easy to open from the inside, and the old man only closes it temporarily, so as not to disturb us. ”

"Don't look at this place, it seems to be our territory, but in this vast space deep in the dark abyss, there are actually many places, and we haven't figured it out yet, there are many powerful demon beasts or monsters that will suddenly break into the area we already control, causing powerful damage to us. ”

As if seeing the uneasiness in the hearts of Yan Wubian and the others, the old man in the animal skin immediately opened his mouth to explain.

Hearing this, the old woman, the old man in the green robe and the others naturally didn't want to say anything, but Yan Wubian had a calm face and didn't seem to care about it at all.

In fact, Yan Wubian's heart was not as calm as it seemed on the surface, from the words of the old man in the beast skin, otherwise he could hear that everything in this underground space was obviously not arranged by the dark demons, and they were also outsiders.

It's just that this group of dark demons should have been here for a long time, maybe a year, maybe a few years, or even longer, and after a long time of exploration, they have a deep understanding of this underground space, so that they can control some formation prohibitions.

Despite this, the complexity of this underground space is probably far beyond the expectations of these dark demons, which makes the old man in the beast skin say that he is worried that someone will disturb them.

When his mind turned, Yan Wubian's pace did not stop, but followed closely behind everyone, and after walking a few feet away, he came to the stone pillars that shone with a dark luster.

These black stone pillars seem to be chaotic, but if you look closely, you will suddenly find that the location of these stone pillars seems to be distributed throughout the space in some mysterious way.

"This is the famous Xuanyin Cold Spirit Array in ancient times, there are a total of nine hundred and ninety-nine stone pillars, each of which is carefully refined with 10,000-year-old Xuantie stone. If you don't understand this formation, if you enter the formation indiscriminately, I'm afraid that in the blink of an eye, you will be permanently frozen here by the cold qi in the formation. The cold wind that opened the stone gate just now was the Xuanyin Qi generated by itself because it was in a sealed space. ”

"Don't look at our cultivation is already very high, but if we really fall into this formation, whether we can survive or not is a matter of two words. ”

The old man in the animal skin reminded softly.

Listening to the words of the old man in animal skin, Yan Wubian and the old man in the green robe couldn't help but glance at the dark stone pillar in front of them a few times, and their faces showed a look of half-belief and suspicion.

"Hehe, don't worry, we are not interested in really experiencing the power of this formation. ”

At this time, Jia Zhenjing chuckled and said.

When the old man in the animal skin heard this, he laughed, and then a wave of power fluctuated on his body, and the array plate in his hand suddenly shone brightly, and it was suspended from his palm, and a colorful glow of light shot out towards the stone pillars in front of him.

Suddenly, where the glow passed, the stone pillars that shone with a dark luster shook for a while, and a passage of a zhang wide flickered one after another like phantoms.

Without delay, the old man in the animal skin grabbed the suspended array plate in his hand with one hand, and took the lead in entering the passage.

When the rest of the people saw this, they followed closely and did not dare to fall down easily.

Yan Wubian, who was walking behind everyone, looked around from time to time.

The surface of the stone pillar looks smooth, but vaguely you can see that there are strange runes tumbling on the surface of the stone pillar, and there is a layer of dark thin ice that instantly covers every inch of the stone pillar.

And looking up, there was a thick layer of black cold mist in the air nearly ten zhang high, and the upper half of each stone pillar was completely submerged in the cold mist, and it was impossible to see the whole picture.

But there is one thing, Yan Wubian can be sure that these stone pillars definitely contain a terrifying cold power, even if it is separated by a layer of body protection aperture, Yan Wubian who has stepped past these stone pillars can still feel the trace of extremely cold power emitted by them, although it cannot be compared with the cold power transformed by the heavenly spirit fire in his body, but this extremely cold power is by no means comparable to ordinary cold qi.

However, what made Yan Wubian even more secretly shocked was that through the gaps in the stone pillars on both sides, he could clearly see that around some of the stone pillars behind him, there were countless corpses standing, squatting, or lying, their faces were frozen in horror, and these people were all dark demons.

Seeing this, Yan Wubian knew why the old man in the animal skin looked jealous after opening the stone gate, obviously, when they came here from the Demon Domain, countless clansmen were killed and injured in this big array.

When Yan Wubian was still thinking about it, the group had already walked out of a distance of nearly a hundred zhang, and these stone pillars seemed to be endless, always arranged on both sides of everyone, it was really hard to believe that there were only nearly a thousand of these stone pillars, and the big array was really magical.

This situation made everyone secretly surprised.

It took a quarter of an hour for everyone to finally get out of the stone pillars, and a huge empty square appeared in front of them. And in the center of the square, a huge pit about ten zhang wide appeared in front of everyone, and above the huge pit, a transparent red light curtain shrouded it tightly.

"Is that the gateway to the Demon Realm?"

Staring at the huge pit not far away, Jia Zhenjing and the others couldn't help but show a sense of joy on their faces, and the thin man couldn't help but ask.

"Not yet, the passage is under the crater. ”

As soon as he put away the array disk in his hand, the old man in the animal skin strode forward, and soon came to the light curtain of the giant pit, and the blue light flashed with his hands, and his palms swelled violently, and his hands were directly pressed on the red light curtain between the shaking of his five fingers.

"Open!"

A wild roar suddenly came out of the mouth of the old man in animal skin, and then, the red light curtain under his palm trembled slightly, and the entire light curtain continued to press forward with his palm, and fell deeply inward.

With a "bang", the red light curtain flashed with a layer of dazzling light, and the entire light curtain was like crystal, shattering inch by inch with the palms of the old man in animal skin, and disappeared without a trace in a blink of an eye.

At the moment when the red light curtain disappeared, Yan Wubian and the others felt a scorching breath, rushing towards them, and they couldn't help but look suspicious and probe their divine senses towards the giant pit.
