Yi Xuan was stunned for a moment, and then followed silently. Yi Xuan didn't need to know where Xuan Yunzi was going to take him, as long as he knew that Xuan Yunzi wouldn't harm himself.

Walking out of the side hall and passing through a group of palaces, Yi Xuan and Xuan Yunzi came to the back mountain of Diyuan Peak. The back mountain is the forbidden place of the Diyuan Sword Sect, and no one can enter it without permission except for the head of the sect. By this time, the sun had set, and a crescent moon had risen silently. Rays of moonlight fall, bringing a hint of coolness.

In front of Yi Xuan was a forest, this forest was extremely large, and there was no end in sight, as if it ran through the entire back mountain. Every tree here is at least a foot tall and grows luxuriantly. I don't know if it's night, or whatever. The forest was pitch black and eerily quiet. From a distance, it looks like a dormant beast, ready to choose people to devour.

Xuan Yunzi stopped, turned his head and whispered, "Xuan'er, the Aoki Phantom Killing Array of my Earth Yuan Sword Sect has been set up in this forest, and it is extremely dangerous. When you get in, you must follow me, pay attention to my walking route, and don't step out of range. If you get caught in the middle of it, you're probably going to have to stay in it for a few days. ”

Yi Xuan nodded seriously in his heart.

Seeing this, Xuanyunzi didn't say anything more, turned his head and took the lead into the forest. Yi Xuan took a deep breath and walked in.

As soon as he entered the forest, Yi Xuan was shocked in his heart. His facial features have been strengthened many times, and he can even see clearly how many legs there are on the mosquito a mile away, and after a range of more than ten meters here, all he sees is pitch black. Yi Xuan looked back, there were still exits, and some were just pitch black. Yi Xuan was stunned, he didn't dare to slack off, and carefully followed Xuan Yunzi.

While only following Xuan Yunzi, Yi Xuan also focused on the environment here. I don't know how long the trees in this forest have survived, and each one is the size of three people hugging each other. The dense foliage covered the sky tightly, and not a single ray of light could penetrate it. It stands to reason that such an environment should be moist and full of snakes and insects. But the land here is extremely dry, and not a single insect cry can be heard around.

The surroundings were silent, but a slight sound of footsteps and breathing was particularly clear here. The Xuan Yun Realm Xuan Master was already able to control his weight and breathing, and Xuan Yunzi would not make a sound when he walked. In this gloomy and vast place, only his own voice was heard, and although he did not encounter any danger, Yi Xuan still felt nervous and uneasy. Carefully paying attention to everything around him, this depression and threat from the soul made Yi Xuan feel very uncomfortable in his heart.

I don't know how long it took, but the darkness that had been hanging over me suddenly disappeared. The cool moonlight sprinkled down, which made Yi Xuan's mind relax instantly. Yi Xuan took a deep breath and exhaled heavily, feeling that his whole body and mind had become light. Yi Xuan took a look at it and found that his realm had suddenly increased by one level, reaching the level of the Xuanshi Quadruple. In the past six years, although Yi Xuan's cultivation has not been able to improve, there is no such restriction in terms of realm. It only took Yi Xuan one year to raise the realm to the peak of the Xuanshi Triple Peak, but in the next five years, no matter what Yi Xuan did, the realm remained at this level. The ups and downs of the period are simply incomprehensible to outsiders.

Yi Xuan couldn't help but sigh in his heart: I didn't expect to be here today, just by walking through this forest, the realm would be raised to the fourth level of Xuanshi. It seems that he is indeed a little behind closed doors, and the improvement of this realm depends on constantly experiencing various tempering.

After a little emotion, Yi Xuan began to pay attention to his surroundings.

This is a group of circular rocks, with countless gray-blue stones standing in a radius of one mile, or squatting, or lying on their stomachs. These gray-blue stones vary in size, from the small ones the size of a fist to the large ones that are dozens of feet tall and resemble a small mountain. Surrounded by a forest, looking down from above, it looks like a gray-blue stone mountain standing under a sea of green.

After coming here, Xuan Yunzi paused slightly, and then entered the group of rocks without hesitation. Seeing this, Yi Xuan naturally followed closely. Entering the rocky group, I turned dozens of corners. Xuanyunzi stopped under an irregular boulder five feet wide and more than a foot high.

The surface of this boulder is pitted and has no features. Yi Xuan glanced around, and there were hundreds of huge stones of similar size and shape to this boulder standing around, and the placement of these hundreds of boulders was irregular. Yi Xuan didn't understand how Xuan Yunzi knew that it was this boulder, and there didn't seem to be any marks on this boulder.

Although he didn't understand, Yi Xuan didn't ask, but looked at Xuan Yunzi silently.

I saw Xuanyunzi gently slap the irregular boulder a few times, and several earthy yellow mystical forces visible to the naked eye entered the boulder with Xuanyunzi's hand. 'Boom' saw the boulder shake violently. Then, Yi Xuan saw that the boulder had directly cracked a hole one meter wide and two meters high from the middle. A pitch-black hole appeared in front of the two of them.

Xuan Yunzi pointed to the opening of the cave in front of him, and said with a solemn expression: "This is the ancestral land of my Diyuan Sword Sect, and it holds most of the Xuanfa, Xuanshu and Xuanqi of my Diyuan Sword Sect. As long as the ancestral land is not lost, our Diyuan Sword Sect will not perish! There are a total of three hundred and sixty identical boulders around here, each of which is a Chongyuan Stone, which was personally transported back by Diyuanzi, the ancestor of our Diyuan Sword Sect, after achieving the Dan Ling, and using his great divine powers!"

Yi Xuan was shocked when he heard this, the heavy yuan stone is extremely heavy, and the weight of this heavy yuan stone itself is probably not less than one million catties! Due to the special material, this heavy yuan stone cannot be loaded into the storage space, and can only be carried piece by piece.

The ancestor of Di Yuanzi is really amazing, these hundreds of heavy yuan stones together have tens of thousands of catties! Yi Xuan couldn't help but admire Di Yuanzi in his heart.

"In addition to the weight of this heavy yuan stone itself, its defensive power is even more powerful! Ordinary Xuan Master powerhouses can only leave a mark a few inches thick on this heavy yuan stone with a full blow. These three hundred and sixty heavy yuan stones were built into a Zhou Tianyuan force array by the ancestor of the Earth Yuan Zi, gathering the weight of three hundred and sixty heavy yuan stones and defending against the heavy yuan stone in front of him. It makes the defensive power of this heavy yuan stone even more amazing, even if the strong man of Xuanzong attacks with all his strength, he can only leave a mark half an inch thick on the boulder!"

Yi Xuan finally saw it, it was worthy of being a sect that had been inherited for three thousand years, and the essence was powerful! Even if a strong person from Xuanzong wants to break in, it will take at least a few years.

Yi Xuan couldn't help but sigh: "The ancestor is really a god!"

Xuan Yunzi nodded approvingly, Di Yuanzi not only single-handedly founded the Di Yuan Sword Sect, but also took great pains to leave many followers. In the past three thousand years, the Diyuan Sword Sect has experienced several catastrophes of life and death, but it is still standing!

"Xuan'er, after entering later, you must remember every step I take, and you must never take a wrong step. In this ancestral land, the ancestor of the Earth Yuan Zi originally only set up three formations, one killing array and two phantom formations. But later, I sent the successive generations of masters to feel that it was not enough, and on the basis of the original formation of the ancestor of the Earth Yuanzi, countless phantom arrays and killing formations were added. Now this ancestral land is full of murderous opportunities, and even if I come here, I will be seriously injured if I am not careful. Xuan Yunzi said to Yi Xuan with a serious face.

Yi Xuan's face was straight, and he nodded seriously. In the Aoki Phantom Killing Array just now, although Yi Xuan did not encounter danger, the crisis from the soul told him: It is definitely very dangerous there! But at that time, Xuan Yunzi's expression was definitely not as serious as it is now.

Xuan Yunzi nodded, and entered the cave with Yi Xuan one after the other.

As soon as the two of them entered, they heard a loud noise, boom~ The boulder shook for a while, and the entrance to the cave slowly closed again. If you hadn't seen it with your own eyes, no one would have believed that there was a cave inside the monolith.

The cave was dark inside, and there was not a single ray of light around it. But the suppression of spiritual power here is not as great as that of the Aoki Phantom Killing Array, and Yi Xuan can still see a hundred meters in front of him by relying on his spiritual perception. The first thing that caught Yi Xuan's eyes was a two-meter-wide stone staircase that continued to extend downward, the stone staircase was very long, and Yi Xuan's perception could not see where the end was.

Yi Xuan followed Xuan Yunzi cautiously, not daring to make a mistake. On the two-meter-wide stone staircase, Xuanyunzi's footsteps sometimes went left, sometimes to the right, sometimes forward, sometimes backward, sometimes several stone stairs in one step, and sometimes only half a stone staircase in one step. After walking for about half an hour, I finished this stone staircase. Yi Xuan breathed a sigh of relief, looked at the stone ladder behind him, and silently calculated in his heart, and found that the total length of this stone ladder was no more than a few hundred meters. Normally, it would have been enough to walk in ten breaths, but now it took a full half an hour. Yi Xuan felt in his heart, although he didn't know what would happen if he took a wrong step, but looking at Xuan Yunzi's expression, I am afraid it would definitely not be easy!
