As he spoke, the entrance of the underground palace over there suddenly lit up. 『』

For this kind of light, everyone is used to it, this is the Yin Yang Gate people trying to close the formation, but the result is not closed, but it will stimulate the counterattack of the formation.

"Boom", another explosion.

He Xilin glanced over there: "There is an unlucky egg that has been burned." ”

Qin Ruo looked over and saw a disciple of the Yin Yang Sect, his hair and clothes were scorched, and everyone was black, it seemed that he had been tricked. But the person was fine, got up and patted the dust on his body, and went to wash with a look of chagrin.

"Having said that, this underground palace is really magical. This means of defense is relatively mild. He Xilin said in wonder.

"It's not gentle at all. A familiar voice came.

Qin Ruo hurriedly stood up, turned to look at Qu Tian who came to his side and asked, "Old Ancestor, why are you here?"

He Xilin also hurriedly came over to give a salute.

Qu Tianwen sat down casually and looked at the gate of the ruins of the underground palace: "I didn't have much interest in this place. However, the disciples drew a rough formation diagram, and I was interested. According to the comprehensive calculation of the computer, the area covered by this formation is more than six square kilometers. A dungeon of this scale is rare in the world, and it is not uncommon for a city of this size to be placed in the world. But in the sect, there is none. At least, we've never heard of a sect or anywhere with such a huge regional structure. ”

Qin Ruo and He Xilin were both extremely surprised.

Six square kilometers, if you calculate the land area, is not very big, but if you calculate the area of a city, it is not small.

According to secular calculations, if it is a complete and comprehensive urban area, six square kilometers is enough for an ordinary county town to live and live for nearly 100,000 people.

Even if there is a sect where the number of people is not so dense, it can at least meet the needs of one or two thousand people.

But what sect can build such an underground structure to provide for so many people to live in

If you don't live in people, it's a warehouse

That's even more scary, what warehouse can be so big

The current sect building, such as the Pure Heart Concept, has so many hundreds of halls, which still include almost all functions. The area covered by square kilometers can never be calculated in square kilometers.

Of course, the concept of pure mind belongs to the category of schools with very small construction area.

However, even the Bixiao Palace, the Kunlun faction, which has a relatively complete palace complex, does not dare to say that it has an area of six square kilometers of construction area

From the current point of view, as far as the Kunlun faction is concerned, one or two square kilometers is not bad. Of course, the cultivation places of individuals scattered everywhere do not count.

Here, however, is a real, six-square-kilometer area, and it is also an underground palace. Obviously, the underground palace must at least open up the underground space, and there must be a lot of buildings inside.

"Is there a record of such a large scale, it stands to reason that such a huge place should not be nameless. Qin Ruo couldn't help but ask.

"That's where the weirdness begins. It stands to reason that if a certain sect has such a large scale, other sects will always know about it, and there will always be a few words left a record. But I searched through all the possible records and found no such record. Moreover, I consulted the records of the pre-Qin era in ancient times, when there was a sect called Qianding Sect, and the sect was stationed in a vast area, but according to the records, I restored it and tried to calculate, and it was only an area of less than two square kilometers. This is already recorded in the book and is called the first sect in the world. Moreover, there are clear records that the area of this sect is unprecedented. As for this vast area, it is by no means the only one. Qu Tianwen said with certainty.

Qin Ruo and He Xilin's curiosity about this place couldn't help but be even more.

"Then I remember that I found some written records here, didn't I say anything," He Xilin couldn't help but ask.

Qu Tianwen nodded: "There are some written records, and I also found some records about the number of people here." But the number of people here, according to our speculation, will not exceed five thousand at most. 5,000 people, why do you need such a huge place"

The rest of the transcripts, but there are no more records. I just know that this sect is called Wanshengmen. More details are not known. Perhaps, the root of unlocking the secrets here lies in this underground palace. Qu Tian asked.

Qin Ruo and He Xilin's eyes couldn't help but look in the direction of the underground palace.

Unexpectedly, the place that I thought was just an ordinary ruin seems to be getting more and more interesting.

"Old Ancestor, what do you think, there might be something here" Qin Ruo couldn't help but ask.

Qu Tian asked and smiled: "If I have that ability, I'm afraid that I can't be as good as an immortal." Wait, when the dungeon is opened, you will naturally know. ”

He Xilin couldn't help but scratch his head: "Ah, that's early, I don't know how much time it will take just to open the door." ”

Qu Tianwen looked at He Xilin with a smile: "If you open it, it is very simple." After all, it is a formation that has been in operation for thousands of years, and we have to organize some masters to forcibly break it, and there is still a way. But we still need to study this magic circle, so naturally we are reluctant to destroy it. ”

He Xilin couldn't help laughing: "I'm a little anxious. ”

"There are too many missing formations now, and any opportunity to study is precious. If we can study this formation well, we will have to improve our formation level a lot.

When He Xilin heard this, he said very depressedly: "Old Ancestor, this is too strange, it is obvious that the formation was so prosperous at that time in Huaxia. Why did you suddenly say that the extinction of the formation was extinct, it was unlikely. There are so many sects, there are always some leftovers, how can it be so simple, so powerful, it can't be all the people who understand the formation, discuss it and give it up collectively, and then collectively destroy the things related to the formation."

Qu Tianwen sighed: "It's not just you who are strange, but so am I. Thousands of years ago, what happened to the end, all the formations of the guide zhì seemed to have been lost overnight, and even the secret strategy of the formation was not passed down. So much so that for so long, our formation level is not as good as those overseas barbarians. If it weren't for you to retrieve a copy of that formation secret strategy, we would probably not be as good as a barbarian now. ”

He Xilin's eyes lit up: "Old Ancestor, does that mean that our current formation has surpassed that of the barbarians?"

Qu Tian asked and smiled: "People are not stupid, won't people develop, although we have recovered a little, but it is impossible to say that it is exceeded." But it's no problem to contend with it. ”

He Xilin was a little disappointed, but this is always a good trend.

"Then if you crack this underground palace, will there be a relatively big development" He Xilin was a little unwilling.

In his heart, Huaxia is always the first, and those people abroad are all overseas barbarian traffickers, and it is difficult for him to accept the fact that Huaxia is inferior to those people.

Not only He Xilin, but most of the sect's disciples have such an attitude.

Of course, such a high-minded attitude is sometimes not necessarily a good thing.

But at least there has been a change at the moment, after all, everyone is no longer the same as before, the sect is so closed, and it has gradually become more enlightened, and the contact with the outside world has also become more.

The mentality is also slowly paying attention to those overseas barbarians in their eyes. This is still gratifying.

Qu Tian asked and smiled: "How can it be so easy, it is certain to improve, but it is unrealistic to improve to a very high level all of a sudden, or even surpass the barbarians, or crush it." This formation, like cultivation, is also gradual, how can it reach the sky in one step, after all, the formation secret strategy we got back is only the most basic formation secret strategy, and those really useful various formation layouts still need to be explored slowly. ”

He Xilin was a little bared, but when he looked at the dungeon, he smiled and said: "That's not necessarily, maybe there is a complete set of ancient formation books in this pre-Qin underground palace." ”

Qu Tianwen looked at He Xilin with a smile: "You, you're still not calm enough." But your words are not wrong, if there is a complete set of ancient formations, it doesn't even need to be too perfect, as long as there are some intermediate or advanced formations, our formations will also take a big step forward, and we can quickly recover. In a few years, you will be able to surpass the barbarians. ”

He Xilin looked at the underground palace, but laughed: "I have an intuition, there must be there there, he, there must be, if not, Lao Tzu will demolish this place." ”

Qin Ruo and Qu Tianwen couldn't help but laugh.

They want to have it too, but it's not something you want to have.

But Qin Ruo calmed down, but suddenly said seriously: "Ancestor, if you want to say that there may be a trap, but there may be a good development, maybe there will be a good development." After all, the extinction of the formation was about a thousand years ago, and this underground palace was something from the ancient pre-Qin era, thousands of years ago. If it were, it wouldn't be surprising. Moreover, it is not normal to say that there are no secrets in such a vast underground palace. ”

Qu Tianwen nodded lightly: "I also hope the same, but the matter of this formation has been lost for too long, but I don't dare to report too much hope, and when the time comes, once I am disappointed, I will also be very aggrieved." ”

Qin Ruo laughed: "I am fortunate to have lost my life, since we have a foundation, we can always develop again." It was an accident to get it, and if you don't get it, it won't hinder us, it's just a matter of time. ”

Qu Tianwen looked at Qin Ruo with a smile: "You can see it." On the contrary, I can't see it."

Qin Ruo smiled: "But what Xilin said is still very possible. This is the pre-Qin underground palace, as long as there is a place like a library pavilion, even if there is no systematic formation here, at least some related things must be there. After all, this sect, just looking at the area on the ground, is also a huge sect. Although I don't know why it was ruined, but with so many people, to say that no one is proficient in the formation, I don't believe it. Here, maybe a real and huge surprise awaits us. ”

Several people's eyes looked in the direction of this dungeon, indeed, this dungeon, maybe there will really be surprises.

At this time, the gate of the underground palace suddenly flickered, and it glowed with blue light twice in succession
