Such a large-scale flash flood, without the slightest warning, broke out directly, and I knew it was strange to think about it with my feet.

However, many geographers have investigated for many years, but they have not come up with a reason.

Or, Lin Nan guessed that those scientists had already investigated the results, but for some reason they could not make them public!

Because the bronze mirror in his hand is the scales of some kind of animal! It can fool Zhao Linghe and the others, but it can't fool Lin Nan!

Just that one is the size of a basin, and according to Lin Nan's experience in fighting with demon beasts in the fairy world, it can probably be estimated that the size of this scaly demon beast is left.

I am afraid that it is twenty meters tall and weighs more than ten tons, which is equivalent to an adult Tyrannosaurus rex during the Jurassic period.

That level of demon beast, Lin Nan felt terrified just thinking about it.

As far as common sense is concerned, the larger the size of the demon beast, the higher the cultivation, if it reaches the level of the demon venerable, it can even be comparable to half an island country, such as the blue-whiskered long-haired demon whale in the fairy world's 'sea of clouds', its body length reaches an astonishing 100,000 kilometers, which is larger than many countries on the earth!

According to Lin Nan's inference, this scale is at least a hundred years old, and the cultivation of that demon beast must be innate at the very least, if it is still alive now, it is possible to build the foundation and even Jindan.

Reminiscent of the strange torrent, the culprit seems to be clear at a glance.

If it is a demon beast in the Jindan period, it is not a lie to turn the world upside down in anger!

Lin Nan guessed that it was very likely that a battle broke out in Yichuan County a hundred years ago, and both sides of the battle were strong, and the cultivation was at least above the foundation.

Their great battle caused the mountains to collapse, floods to erupt, and the violent overflowing internal force caused spiritual turbulence in Yichuan County, and the air could not circulate and was blocked together, and then through the fusion of internal and spiritual power...

In the end, there was an unprecedented explosion!

Its power is more prosperous and the golden pill period will explode!

Of course, these are just Lin Nan's speculations.

He wasn't sure what the truth was, after all, more than a hundred years had passed, and even if there were any clues, they would have long since faded away.

Soon, Zhao Linghe appeared with two maps in his hand.

Lin Nan put it on the table with a solemn expression and spread it out, comparing them one by one.

Cao Dong stood up and said: "Sect Master Lin, you see, here, here, and here, they all originally belonged to the Lianyan Mountain Range, but since the flash flood in 60 years, four mountains have collapsed! Although they still exist now, they are all half dwarf and have become small hills. ”

Lin Nan frowned, took out a pen and wrote on the map.

His appearance was extremely serious, which made Qin Xiaoxi, who was sitting next to him, look a little stunned.

Lin Nan gave her an indescribable strange feeling, she was a five-rank Dan Dao master, but she was proficient in bartending, and she was suspected of being a martial artist, coupled with her calm bearing and calm personality, she was like an old man who had lived for hundreds of years to return to her youth.

'How can there be such a weird person?'

Qin Xiaoxi was in a complicated mood.

Although she is not very old, because she is in a high position, she has a lot of contact, all kinds of people, but Lin Nan is the only one who gives Qin Xiaoxi the illusion that she is in a fog, and she can't see through it at all.

Qin Xiaoxi couldn't help but glance at Wang Xiaoruo, who was stupidly drinking tea next to her, and said in her heart that maybe she could start with this woman and set Lin Nan's identity.

At this time, the two maps had been marked with dense red dots by Lin Nan.

Ordinary people looked like their eyes were clouded, and the red dot marks were disorganized, and it seemed that there was no meaning at all, but Lin Nan did it easily.

No one could understand what he was doing.

At first, Qin Xiaoxi was the same, his eyes were full of confusion.

But she looked closely at the map, and her heart pounded.

It's true that the red dots are disorganized, but when the two maps are combined, there is a vague pattern.

It is the prototype of the formation!

Qin Xiaoxi gasped, she looked at Lin Nan in disbelief, what kind of head could connect the mountain torrent with the formation?

But all this evidence tells the truth.

The flash flood in Yichuan Prefecture in 1960, which shocked the whole country, was not accidental!

Qin Xiaoxi was chilled!

She felt like she was approaching a whirlpool, bottomless and devouring at the slightest touch.

And the mystery in the whirlpool is about to be uncovered by the young man in front of him.

Qin Xiaoxi was shocked in her heart, she had more contact with the martial arts world, and she knew very well that wherever the world changed, there must be good things!

Or even if she didn't, Qin Xiaoxi's natural curiosity made her look forward to Lin Nan uncovering the mystery!

For a rich second generation like Qin Xiaoxi, ordinary fun doesn't make much sense, and she has had enough of the life that ordinary people dream of as a child, otherwise drug addicts will not be the majority of rich second generations, they just have enough of ordinary fun and try to be new.

Therefore, for Qin Xiaoxi, there is nothing more exciting than diving into that big whirlpool in person!

At this time, Lin Nan frowned.

He excluded several mountains on the periphery of the Lianyan Mountain Range in turn, and according to the feng shui theory of 'arching and interdependence' in the formation, as long as it is a formation, there must be a formation heart.

Having a formation means that there must be a formation to support it, and when combined with each other, a complete formation can be formed.

And the 'Lianyan Mountain Range' is obviously a super power, a great array set up in ancient times!

With the mountains as the base and the water and wood as the line, the center of the formation is connected together!

This kind of big means can only be done in the Mahayana period at least in the Mahayana period, and even the Immortal Emperor!

In addition, the people who set up the formation are obviously quite attained, and this 'Lianyan Mountain Range Great Array' at first glance looks like every mountain can become the center of the formation, which is very confusing to people's eyes.

Fortunately, it was Lin Nan who discovered this mystery.

He had practiced formation in the Immortal Realm, although he was not very proficient, but he was not comparable to a little Immortal Emperor.

Lin Nan solemnly put his finger on the map, and then slowly moved...

Finally, stop at a large blue-black mountain.

When Lin Nan's gaze stopped, everyone in the VIP reception room exclaimed.

Their voices were filled with ominous and frightened tones.

"Senluo Mountain!"

Zhao Linghe, Cao Dong, Cao Shuang... All the local people in Yichuan County looked embarrassed and shouted out in unison.

Lin Nan was slightly surprised, judging from everyone's reactions, this mountain was definitely not ordinary! It also confirmed the possibility of being the center of the formation from the side.

"Mr. Zhao, can you tell us more about this mountain?" Lin Nan asked seriously.

"Yes, yes, yes. ”

Zhao Linghe's expression was extremely strange, "In fact, as long as the legend of Senluo Mountain is a native of Yichuan County, they all know more or less, and it is famous... Tourism and suicide mecca. ”

"How do you say this?" Lin Nan couldn't help but be more interested in his heart.

Qin Xiaoxi coughed, "Let's talk about it, in fact, I planned to go to Senluo Mountain last year, but I didn't find the opportunity, and these survey results will be cheap for you." ”
