After breaking through the Ten Dao Five Elements Prohibitions, Yun Ziyuan continued to walk towards the bottom of the tunnel, the next prohibitions were not a problem for him, with prior preparation, he only needed to spend a little time to pass safely.

And in this process, Yun Ziyuan is also analyzing little by little, looking for some of the background of the times and the owner information that may be revealed in the prohibition.

For example, from the oil lamps on the wall, Yun Ziyuan can see that this cave is 10,000 years ago; from the use of the Five Elements Prohibition, Yun Ziyuan can also see that it is very likely to be in the era of the Five Elements Divine Dynasty; from this spiraling downward tunnel, Yun Ziyuan can also see that the owner of this cave should be a righteous hermit, a hermit who rarely goes out and concentrates on cultivation......

"In the era of the Five Elements Divine Dynasty, the way of the hermit was quite popular, and many monks went to various mountains to open caves and retreat from the world. And this tunnel presents a spiral downward, and all kinds of prohibitions are arranged in layers, which makes me think of the prohibition method of the thirty-three heavens, although it is not exactly the same as this, but there are many similarities, and the thirty-three heavens are the common prohibition methods thousands of years ago, and they were mostly used by hermits at that time, perhaps, the prohibition method of the thirty-three heavens may have evolved from this......"

Thinking of this, Yun Ziyuan couldn't help but feel that although compared to a historical living fossil like Zhaotian City, the establishment of Tianmen was still very short, but the so-called "heritage" that Tianmen had collected by relying on its strength was still very profound.

"Thanks to the book gallery in the Nine Heavens Tower, I can have such a knowledgeable ......"

This is not Yun Ziyuan's boasting, the Tianmen collection of books is involved in ten thousand ways, and now it is all in Yun Ziyuan's mind, so he can't help but become a learned person.

......

A whole day passed, Yun Ziyuan got closer and closer to the bottom of the tunnel, and he estimated that he had traveled at least 10,000 miles in this tunnel, of course, if it was converted into a straight downward distance, it would be about 3,000 miles.

"I don't know how high the mountain where this cave is located, otherwise I would know how deep I am now......

Yun Ziyuan thinks that he has now reached the depths of the earth, but he doesn't know how deep, he thinks so, because although Shenzhou is vast, and the mountains of three thousand miles high are not particularly rare, they are basically mountains with masters, or occupied by the strength of the great sects, or inhabited by immortals who escape the world, and the monks of the Daoyan realm are far inferior to the current Tianmen Divine Lord in terms of status in the era when there are still immortals.

Yun Ziyuan was thinking nonsense as he walked, and at this moment, what appeared in front of Yun Ziyuan's eyes was the last prohibition.

This is a very special prohibition, there is no special ability, there is no cruel means of killing, nor is it a formation that traps people for a lifetime, just a barrier, an incomparably strong vitality barrier.

What Yun Ziyuan saw in front of him at this moment was a prohibition that was extremely similar to the Yuan Qi barrier that appeared when ordinary monks broke through the realm and were quiet, but this Yuan Qi barrier was artificially gathered, and it was not as quickly dispersed as when the monk broke through the realm and was quiet, but it had existed for so many years, and it had existed for 10,000 years, and no matter how thick the Yuan Qi barrier was, there would always be a day when it became thinner.

Yun Ziyuan stretched out his hand and pressed on the Yuan Qi barrier, and immediately a very strong repulsive force came out, wanting to force Yun Ziyuan back, but Yun Ziyuan just stepped back with his left foot, pushed it back, and even passed his hand through!

"This intensity, only at the level of tranquility, is much weaker than the previous prohibitions......

Yun Ziyuan's feet shook, and the whole person flew in diagonally like a sword, tearing apart the entire Yuan Qi barrier, but after Yun Ziyuan entered, the Yuan Qi barrier was only a few minutes weaker, and then it was unified again.

After breaking through, Yun Ziyuan looked back and saw that there was a gourd hanging from the wound of this Yuan Qi barrier, and these Yuan Qi flowed out of the mouth of this gourd, forming a Yuan Qi barrier.

"The vitality stored in this gourd is constantly pouring down, not only forming this vitality barrier, but also supporting the operation of other prohibitions!"

Strictly speaking, this is not a ban, but the source of the ban, so this Yuan Qi barrier does not have a forbidden name, Yun Ziyuan looked at the gourd and did not move it. Although the gourd is only a dead thing, it can carry so much vitality, and it can flow for thousands of years but it has not disappeared, it is obviously an extremely terrifying thing, and Yun Ziyuan naturally will not easily touch it.

Turning around, Yun Ziyuan walked down the last section of the tunnel and came to a small room, the four walls were smooth, and there was nothing else in it, except a small table in the style of an altar, on which was placed a crystal ball, with colored light inside, which was extremely bright.

"Is this the core of the cave......

Yun Ziyuan stepped forward and picked up the crystal ball, only to see that its feet were the size of a human head, crystal clear, with divine light vertical and horizontal, green glow, giant trees flying sideways, and golden light...... He took the crystal ball and searched for a long time, but he didn't find any patterns and patterns, nor did he find any text symbols, which was very mysterious.

"There are no special markings, how do you know where it came from......"

Yun Ziyuan put the crystal ball back, rummaged through this small space again, and used it for his soul, but he still couldn't find any strange place, and this was the biggest strange place.

"Could it be that this hermit is really hidden to such an extent, not only hiding in the mountains, but also unwilling to leave any text patterns, he wants to completely cut off contact with the outside world?"

At this moment, Yun Ziyuan suddenly remembered, the lone swordsman had said before that there were no magic tools left in this cave mansion from the previous master, and there were no scriptures and cheats, except for a few bottles of pills, a few tables and chairs, some bamboo slips without words, and even some simple living utensils, which was very strange!

Although the monks of the Daoyan realm don't need any living utensils, if this really doesn't exist at all, it actually reveals a little weirdness.

Yun Ziyuan couldn't help but wonder, what was the reason for this situation? Could it be that it ......

Suddenly, Yun Ziyuan had an idea, and thought of whether it could be that this mysterious Daoyan monk finally encountered some special enemy, and in order to escape for his life, he moved everything here to another cave, and this was just one of his ...... Bait?

"The Three Caves of the Cunning Rabbit ......"

After a while, Yun Ziyuan shook his head, this kind of thing can't be thought of just by thinking about it, he picked up the crystal ball again, and muttered to himself: "No matter what weirdness it is, it has nothing to do with me, I'll open the cave first and solve the current crisis!"

Yun Ziyuan held the crystal ball in one hand and the wooden key in the other, he walked along the same road for a long time, with the crystal ball in his hand, those prohibitions did not attack Yun Ziyuan again, and Yun Ziyuan finally returned to the cave safely.

"You're back......"

As soon as he saw Yun Ziyuan appear from under the floor, the lone swordsman immediately greeted him, and he wrapped the crystal ball with the cloth he had prepared long ago, without causing it to leak any brilliance.

"What are you ......" Yun Ziyuan asked puzzled, he quickly saw that the cloth used by the lone swordsman to wrap the crystal ball was not an ordinary thing, and there was a strong isolation aura, so that Yun Ziyuan could not detect the condition of the crystal ball now.

The lone swordsman wrapped the crystal ball tightly, and then said to Yun Ziyuan: "This is a vein sealing cloth, which can cover the breath of anything, and when we open this crystal ball later, it will cause a very unusual forbidden aura, in order to prevent these breaths from spreading to the outside world, we need to cover it ......"

I see, Yun Ziyuan nodded in understanding. But in an instant, Yun Ziyuan realized that the crystal ball that opened the cave mansion could cause the formation forbidden aura to spread to the outside world, which didn't seem to match his identity as a hermit!

Especially since the lone swordsman also said before, the mountain where this cave is located is not very far away from Tianyi City, so this is even more wrong!

"Could it be that my conjecture is correct, this strange cave is really just a bait to attract that Daoyan monk's enemy?"

Yun Ziyuan was distracted for a while, and his mind was constantly speculating about this cave mansion and this Daoyan monk. The lone swordsman saw Yun Ziyuan's strange appearance, so he called Yun Ziyuan.

"Hmm!?What's wrong?"

The lone swordsman glanced at Yun Ziyuan strangely and said, "What's wrong, I still have to ask you what's wrong, why have you been in a state of soul since you came out of that tunnel?"

"Is there one?"

Yun Ziyuan came back to his senses and told some of his guesses about this cave, wanting to hear the opinion of the lone swordsman, he had been in retreat in this cave for so many years, and he might not know much about the background and history, but he definitely had more details about the cave than himself.

The lone swordsman was stunned when he heard this, he didn't say some other strange things about this cave mansion as Yun Ziyuan thought, but looked at Yun Ziyuan with an even more strange look, and said: "Why do you think so much, this is all ten thousand years ago, do you still want to investigate the whereabouts of this Daoyan monk, do you want to get his inheritance, or do you want to avenge him......

This time it was Yun Ziyuan's turn to be stunned, and when the lone swordsman said this, he realized that he was indeed thinking about some miscellaneous meaningless things. Indeed, no matter what the purpose of that Daoyan monk was in laying this empty mansion, this was ten thousand years later, and he couldn't fight them anyway, so there was no need to dwell on it at all.

Immediately afterwards, Yun Ziyuan realized that it was because he really came to an ancient ruins for the first time, and it was the first time he really explored the rivers and lakes, and there was a simple desire for adventure in his bones that was urging Yun Ziyuan to think about it.

Realizing this, Yun Ziyuan shook his cheeks a little funny, and immediately put on an indifferent expression in a blink of an eye, because he realized that he couldn't show an impulsive and jerky appearance in front of the lone swordsman, which was not in line with what he told the lone swordsman about his experience of traveling to Shenzhou to find Jian Xuan!

But fortunately, the lone swordsman didn't care about this, or rather, he didn't know Yun Ziyuan deeply, he didn't know all of Yun Ziyuan's character, and he didn't know what Yun Ziyuan's performance meant, he just said to Yun Ziyuan: "You can insert the key into this crystal ball, you can open a path to the core area of this cave, and the healing formation I need is inside." ”

"Okay!"

Yun Ziyuan had completely put his mind back, he took out the wooden key, and said calmly.
