After spending a lot of money, he finally successfully cracked the remnants of Jian Zong's protective formation. Entering the Tiankeng from the underground palace, Xu Zhengdao also saw the Jian Zong ruins that still had a somewhat majestic atmosphere. The Jian Zong here is better than the Jian Zong above. It's even more majestic.

It is a pity that the Jianzong located in Tiankeng is still a ruins. From a preliminary inspection, it can be seen that the buildings here are still mainly made of masonry and wood. The masonry can still be preserved, but many of the wood are decayed and dilapidated.

But what shocked Xu Zhengdao was that many of the timbers used in the buildings at these ruins were still well preserved. If he read correctly, these building timbers were all made of non-corrosive nanmu or ironwood.

"Such ancient buildings are really rare in the world today. Just those pillars, any one transported out of the mountain, is probably worth a lot of money. Even the wood used in the Imperial City is probably far inferior to that used by the Sword Sect."< /p>

Earlier in the capital, he purchased a lot of furniture made of rare wood. Therefore, he naturally has a good understanding of some rare woods. In the early years of Shu, the land of Shu itself was rich in golden nanmu, so it was naturally easy for Jian Zong to collect it.

However, there are not many golden nanmu trees that are so wide and used as beams and pillars in the world today. If the archaeological team knew that there are such magnificent and precious ancient buildings in this tiankeng, I am afraid they would also feel comforted for the rest of their lives!

But Xu Zhengdao knew very well that with the capabilities of the archaeological team alone, it would be impossible to enter the Jianzong's location under the sinkhole. If there were no accidents, there would probably be protective measures above 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 that such an ancient building complex exists here, it may be possible to break through the remaining formations by using artillery fire or bombing coverage.

If you try to break the formation by manpower alone, you are afraid that if you summon all the martial arts masters in the country, they will most likely be killed here. Perhaps those masters are extremely powerful but do not know how to break the formation. Even if they use human lives to pile up the formation, they may not be able to break the formation.

Even if Xu Zhengdao was able to successfully break the formation, it was all thanks to the formation-breaking talisman he signed in before. Through this incident, Xu Zhengdao finally understood that everything he signed in to the system seemed to be useful, and It cannot be used easily.

What made him breathe a sigh of relief was that the Jianzong ruins above had remaining formations, but the Jianzong in the Tiankeng did not. After entering several buildings, he did not feel the existence of the formations. But the useful things, Still very few!

After walking around a few buildings, Xu Zhengdao said thoughtfully: "If Jianzong declined naturally, then it would be impossible for this group of buildings to be so well preserved. What's more, there are obvious signs in this house. All cleaned up.

Although you can see some furniture and daily necessities used by ancient people, you can't see anything valuable or rare. The whole house feels like it was packed up specially when moving and left at the end.

That means that the people from the Sword Sect may have left. They are the last descendants of the Sword Sect and were forced to leave. Or maybe there are other reasons? There is always something extraordinary and unique about the Xuanxiu sect that has been passed down for a long time. Right?"

In Xu Zhengdao's view, since there have been a large number of Xuanxiu sects in this space, and these Xuanxiu sects eventually left and disappeared, there is only one explanation: they went to other dimensions to continue living.

So how did they leave? Is there a world of cultivation in this world? Is it really possible to go to that world through the teleportation array? If this is the case, it is easy to explain why Jian Zong chose to move away!
p>

The mystery that is now left to Xu Zhengdao is that the senior sword cultivator who took the reincarnation of Kunlun was the successor of the Sword Sect who was left behind on earth, or did the Sword Sect disappear after him?

But according to the ancient books he has seen so far, although there were many Xuanxiu in the Tang Dynasty, there were very few written records mentioning the Sword Sect. To be precise, the few words about the Shushan Sword Sect that can be found seem to be pushed to the Shang Dynasty.

Zhou period.

In that era, there were many talented people and strangers everywhere. But in the unified Qin Dynasty, and in the following years, the legends about high-level mystical cultivators gradually became less and less. So what happened in the meantime?<

/p>

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

Fortunately, many truths have been buried in the long river of history, so I don’t have to dig too deep. I just hope that the next exploration will bring me some gains. Otherwise, I’m afraid I will really lose a lot.”

During the visit to the Jianzong ruins, he would put some antique furniture that Zhengdao thought was good into the cave space. And some wood that looked like it was about to decay, he would also put it into the space and turn it into nutrients.
p>

Because the space at this moment is already full of green trees. Some of the nanmu seedlings that were dug before are now growing very well in the space. The nutrients devoured and differentiated will also help these trees grow more lushly.

Looking at the evolving space, Xu Zhengdao said thoughtfully: "Maybe it's time to release some animals into the space. I just don't know if the animals released into the space have a chance to evolve into so-called spiritual beasts?"

According to the system's explanation, the Dongxuan space, which has the function of constantly evolving, has the opportunity to evolve into a small world. Since the Dongxuan Ring has such a function, who can guarantee that no great power will open up a world of cultivation for Xuanxuan cultivation?

Where is shelter?

It would be very difficult to enter such a small world and then come out of it. But Xu Zhengdao didn't know whether such speculation could hold water. After all, space is still very weak now!

When Xu Zhengdao arrived at a building that should be the Jianzong Sutra Pavilion, he saw a few books placed on it. Before he could reach out to touch it, the door was pushed open.

Weathering condition.

Looking at these books that turned into ashes one after another, Xu Zhengdao also smiled bitterly and said: "What a sin! Judging from the degree of weathering of these books, I am afraid that no one has visited this Sutra Pavilion for at least a thousand years."

But what made Xu Zhengdao happy was that among these weathered books, there were still some books that were still preserved. But after touching them carefully, he discovered that although these were paper, they should all be specially made leather paper in ancient times.

Compared with ordinary paper, leather paper will undoubtedly last longer. Even through his mental power, he also discovered the existence of some wooden slips. From these things, it can be seen that the Sword Sect has been passed down for a long time.

"Wooden slips, bamboo slips, and even cloth were more popular before the Qin Dynasty. Paper was only invented in the Western Han Dynasty. In addition to the senior Jian Zong who was enthroned, Jian Zong can at least confirm that there were still people lurking here in the Tang Dynasty.

Repair.

Beyond the Tang Dynasty were the Song, Yuan, Ming and Qing Dynasties, but these books and buildings were abandoned for at least hundreds of years or even nearly a thousand years. That means that Jianzong was completely uninhabited, at least before the Qing Dynasty!"

Through these clues, Xu Zhengdao continued to analyze some of his judgments. Through the complete abandonment of Jianzong, he roughly analyzed the era when Xuanxiu declined. In the Qing Dynasty, although Xuanxiu still existed, it became extremely rare and rare!<
