At a great cost, he finally succeeded in cracking the remnants of the Sword Sect's Sect Protector Formation, and entered the sinkhole from the underground palace, Xu Zhengdao also saw the ruins of the Sword Sect that still had a bit of a majestic atmosphere. The Sword Sect here is several times more majestic than the Sword Sect above.

It's a pity that the Sword Sect located in the Tiankeng is still a ruin. From the preliminary inspection, the buildings here are still mainly made of brick and stone and wood. The masonry is still preserved, but much of the wood is rotten and dilapidated.

But what shocked Xu Zhengdao was that there are still many well-preserved timbers from these heritage buildings. If he was not mistaken, the building timber was made of non-decaying nanmu or ironwood.

"Such ancient buildings are really rare in the world today. Just those pillars, any one of them is carried out of the mountain, I'm afraid it is worth a lot. Even the wood used in the Imperial City is far inferior to that used by the Sword Sect. ”

Earlier, in Beijing, a lot of furniture used in rare wood was acquired. So he naturally knows a lot about some rare wood. In the early years, the land of Shu was rich in golden silk nanmu, and it was naturally easy for the Sword Sect to collect it.

But there are really not many golden silk nanmu that is so wide and acts as a beam and pillar that has survived today. If the archaeological team knew that there were such magnificent and precious ancient buildings in this sinkhole, I am afraid they would also feel comforted!

It's just that Xu Zhengdao knows very well that with the ability of the archaeological team alone, if he wants to enter the Sword Sect located at the bottom of the sinkhole, I'm afraid it's impossible at all. If there is no accident, there are also protective measures on the sinkhole.

If you want to enter here, you can only enter from the place where he broke the formation before. Unless the above knows for sure, there is such an ancient complex here, and it may be possible to break down the remnants of the formation by using artillery fire or bombardment.

If you want to break the formation by relying only on manpower, I am afraid that if you gather all the martial arts masters in the country, it is very likely that you will die here. Maybe those grandmasters are extraordinary, but they don't know how to break the formation, even if they use human lives to pile up, they may not be able to break the formation.

Even if Xu Zhengdao can successfully break the formation, it will all be thanks to the formation breaking charm that he signed in before. Through this incident, Xu Zhengdao finally understood that everything obtained from the system sign-in seems to have a time to use, and it cannot be used easily.

To his relief, there were remnants of the formation at the Sword Sect ruins above, but not at the Tiankeng Sword Sect. After entering several buildings, he didn't even feel the existence of the formation. But there are still very few useful things!

After turning around a few buildings, Xu Zhengdao said thoughtfully: "If the Sword Sect is in natural decline, then it should be impossible for this complex to be preserved so well." What's more, the house is obviously cleaned up.

Although you can see some furniture and daily necessities used by the ancients, you can't see any precious and rare things. The whole house feels like it was specially cleaned up when moving and left last.

That means that the people of the Sword Sect may have left. is the last descendant of the Sword Sect, and he was forced to leave, maybe there are other reasons? The long-standing Xuanxiu sect always has something extraordinary and different, right? ”

In Xu Zhengdao's opinion, since there were a large number of Xuanxiu sects in this space. Moreover, these Xuanxiu sects all left and disappeared one after another. Then there is only one explanation, they went to other dimensions to continue their lives.

So how did they leave? In this world, is there a cultivation realm? If you go to that world, can you really pass through the teleportation array? If this is the case, and the Sword Sect chooses to move away, it is easy to explain!

When the mystery left to Xu Zhengdao now, the sword cultivator senior who sat in Kunlun was the descendant of the Sword Sect who was left behind on the earth, or was it after him that the Sword Sect disappeared?

But as far as the ancient books he has seen so far, although there is no shortage of Xuanxiu in the Tang Dynasty, there are very few written records mentioning the Sword Sect. To be precise, it seems that the words of the Shushan Sword Sect can be queried to the Shang and Zhou dynasties.

At that time, talented people abounded. But in the unified Qin Dynasty, and in the following eras, the legends about the high realm of metaphysics have gradually decreased. So what happened in between?

Thinking of this, Xu Zhengdao also smiled bitterly: "Others travel and explore, always hoping to solve some so-called mysteries. But although I know a lot of things that ordinary people don't know, I have also accumulated more mysteries.

Fortunately, many truths have been buried in the long river of history, and I don't have to get to the bottom of it. I just hope that the next exploration will bring me some gains. Otherwise, I'm afraid it's really a big loss. ”

In the process of visiting the ruins of the Sword Sect, some antique furniture that he felt good about the righteous path would be collected into the cave space. And some wood that looks like it is about to rot, he will also store it into the space and turn it into nutrients.

Because the space at this moment is already full of green trees. Some of the Nanmu seedlings that were excavated before are now growing very well in the space. These nutrients that are engulfed and differentiated will also help these trees grow more luxuriantly.

Looking at the ever-evolving space, Xu Zhengdao said thoughtfully: "Maybe it's time to put some animals into the space." It's just that I don't know, do the animals that are released into the space have a chance to evolve into so-called spirit animals? ”

According to the explanation of the system, the cave space with the function of continuous evolution has the opportunity to evolve into a small world. Since the Cave Xuan Ring has such a function, then who dares to guarantee that there will not be a great power to open up the cultivation realm for Xuan Xiu to live in?

It's just that if you want to enter such a small world, and then want to come out of the small world, I'm afraid it's not easy. But whether such speculation can hold up, Xu Zhengdao is unknown. After all, the space is still very small!

When Xu Zhengdao came to a building that should be the Sword Sect Transmission Pavilion, he saw that there were only a few books placed on it, and before he could reach out and touch it, the moment the door was pushed open, it was weathered.

Looking at these books that have turned into ashes one after another, Xu Zhengdao also smiled bitterly: "What a sin! Judging from the degree of weathering of these books, I am afraid that no one has been here for at least a thousand years in this pavilion. ”

But what makes Xu Zhengdao happy is that from these weathered books, there are still some books that are still preserved. Just after touching it carefully, he found that although these were paper, they should all be special leather paper made in ancient times.

Compared with ordinary paper, the life of vellum paper is undoubtedly longer. Even through his psychic powers, he discovered the existence of some wooden tablets. It can also be seen from these things that the Sword Sect has been inherited for a long time.

"Wooden slips, bamboo slips, and even cloth and silk were more popular before the Qin Dynasty. Paper, on the other hand, was only invented in the Western Han Dynasty. Coupled with the sittingly Sword Sect senior, the Sword Sect can at least confirm that there are still people cultivating here in the Tang Dynasty.

Outside the Tang Dynasty were the Song, Yuan, Ming, and Qing dynasties, but these books and buildings were abandoned for at least a few hundred years or even nearly a thousand years. That means that the Sword Sect is completely uninhabited, at least until the Qing Dynasty! ”

Through these clues, Xu Zhengdao constantly analyzed some of his judgments. Through the complete abandonment of the Sword Sect, the era of the decline of Xuanxiu is roughly analyzed. In the Qing Dynasty, although there were still metaphysical cultivations, they had become extremely rare and rare!
