In the afternoon of the next day, Wuyunshan Town welcomed a group of young people one after another. Wuyun Mountain is not far from Y City, about two and a half hours by car. Cheng Yifan only felt that he hadn't finished enjoying the beautiful scenery along the road, so he was told that he had arrived at Wuyun Mountain.

Looking up, the mountains are mountain after mountain, dense, and layered; The endless mountains are shrouded in clouds and mist, and there are many strange peaks; The abrupt mountains are high or low, flat or round, flat or pointed. Some of the colors of the mountains and forests are as green as the sun, some are fresh as the dawn, some are as black as ink, and some are as gray as snow. Not far away, there are two gate-shaped peaks, which are very high from afar, with an altitude of more than 2,000 meters. Two small mountains stand side by side, like a pair of doors opening on either side of the road. In the middle of the mountain, a mountain road more than six meters wide crosses. Under the cover of clouds and mist, the shape of the mountain looms, making people feel as if they are in a fairyland.

However, looking north along the door-shaped mountain road, it is a different scene. I saw a golden black mountain standing due north, and the altitude was estimated to be more than six or seven thousand meters. The mountain is not only high, but also very wide and long, with a length of more than 200 kilometers. Because there are other peaks around it, Cheng Yifan can't estimate its width, but feels that it is very wide and wide.

Mountains tend to give people a sense of being huge and calm; However, the mountain feels unusually eerie. Cheng Yifan is also the first time to see such a black mountain.

"It's obviously a green tree, why does it look so black?" Cheng Yifan sighed incomprehensibly in his heart.

The black mountain was surrounded by several huge dark clouds. The clouds came down from above, from left to right, like a black dragon that had been cut in five. And this mountain looks dark and terrifying under the shroud of this huge dark cloud.

At this time, there was a thunderous sound like a dragon's roar from the top of the mountain. The thunder came into his ears, and Cheng Yifan's heart suddenly trembled. He seemed to hear the call of a distant relative, with a hint of desolation and sadness in his kindness. At the same time, he felt the reincarnation bead in his chest flutter a few times.

"Is this going to rain?" Cheng Yifan asked puzzled.

"Don't worry, it won't rain. There is thunder in these five cloud mountains, and it does not rain. The last time it rained was 25 years ago, the day I was born. That's how my name came about. Gao Yunliang took over as he drove.

Heizi pointed to the black mountain opposite and said to Cheng Yifan: Did you see the five dark clouds on the mountain in front of you? This is the reason for the origin of Gounshan. ”

"Won't these five clouds disperse?" Cheng Yifan asked curiously.

"It hasn't been dispersed for hundreds of years!" Gao Yunliang pointed to the mountain in front of the car window with his left hand and continued: "The one on the top that looks like a dragon's head dissipated when it rained 25 years ago, but it came back after the rain stopped. According to the elder man in the village, the cloud disperses every 25 years. ”

"Is it so evil?" Cheng Yifan asked in disbelief.

"Don't say it, there's something more evil!"

"What is it?"

"Do you know why Kuroko and I are so dark?" Gao Yunliang asked rhetorically with a serious expression.

"Why?" Cheng Yifan was also very curious at this time, and asked seriously.

"Dye this black mountain, hahaha......" Gao Yunliang laughed.

Zhao Yawen followed Gao Yunliang's words and said with a smile: "This is called the black of the near-ink, hehehe."

"Yawen, you are good at geography, introduce this Wuyun Mountain to Cheng Yifan!" Gao Yunliang proposed.

"Hmm!" Zhao Yawen nodded.

Wuyun Mountain is located at the junction of Yunnan-Guizhou Province and 100,000 Mountains, with a total length of 260 kilometers and an east-west direction. It is about 160 kilometers wide and runs in a north-south direction. Because Wuyun Mountain starts here in the south, and connects 100,000 mountains in the north, and it is 100,000 mountains that cross Wuyun Mountain, so Wuyun Mountain is equivalent to the south gate of 100,000 mountains.

The sea of the highest peak of Wuyun Mountain is 7,600 meters, the average mountain height is more than 3,000 meters, there are many basins and deep valleys in the mountains, the mountain is high and the water vapor is heavy, and the clouds and mist are perennial.

Wuyun Mountain is a karst geology, with a wide range of landforms such as residual hills and peak forests, dissolution depressions, limestone troughs and valleys, karst caves, and underground rivers.

I heard that Mr. Jin once passed by this place, and inspired by this landform, most of the male protagonists in the book fell off the cliff, fell into the cave, and then practiced peerless magic skills. If Brother Yifan has this ambition, he can't help but find a shorter mountain bag to try, and maybe he will be famous.

"Hehehe......" Zhao Yawen joked with Cheng Yifan and said with a smile.

"Hehehe...... It doesn't have to be! Cheng Yifan smiled wistfully.

Cheng Yifan found that it was really easy to be with Gao Yunliang and their group. Even Zhao Yawen, who is usually quiet, is very lively and humorous, like a sprout in early spring, which makes people feel fresh and full of vitality.

Soon after passing through the gate-shaped mountain, we arrived at the town of Goun.

Located at the foot of the Great Black Mountain, Wuyun Town is a basin surrounded by mountains on three sides. There is a six-meter-wide road to the south that leads to the mountain gate. This road is the same road that Cheng Yifan and they just drove into.

The Great Black Mountain is located directly north of Wuyun Town, while the east and west mountains are shorter, connected to the Great Black Mountain, forming an encirclement trend. At the foot of the mountain is a rice paddy field that stretches from the foot of the mountain to the edge of the city.

Wuyun Town is an ancient city, and the city walls and gates are well preserved. The 20-meter-high city wall surrounds the foot of the mountain, like a circular iron bucket.

In Cheng Yifan's previous cognition, the ancient city is square, with four gates, southeast, northwest and northwest. And this kind of garden-shaped ancient city Cheng Yifan is the first time to see it.

There are five gates in this city: one in the southeast and one in the southwest, which is the only gate that allows you to enter the city; The two gates due east and west lead to the two mountains; There is also a gate due north, and this gate is not under the city wall, but above the city wall, and it is a small gate more than half a meter wide. There were dozens of stone stairs in front of the small door, and behind it was a black passage that led to the black mountain.

The city gate of Wuyun Town is a stone step gate, there are more than a dozen steps, and cars can't enter the city, so they can only park in an open place outside the city.

Just when Cheng Yifan was thinking about it, Gao Yunliang parked the car and walked over.

Gao Yunliang took it easy, put his arm around Cheng Yifan's shoulder and smiled: "I've never seen this kind of building, right?"

"Yes!" Cheng Yifan replied casually, but his eyes did not leave the city.

Gao Yunliang knew that Cheng Yifan was more interested in ancient architecture, and he often read him to collect such books when he was in college.

"Yawen come here, let him increase his knowledge! Haha......" Gao Yunliang pulled Zhao Yawen on the side to Cheng Yifan.

Zhao Yawen wore a black dress today, her long hair fluttered slightly under the light breeze, her delicate face, and her slender legs, Cheng Yifan couldn't help but take a second look.

Zhao Yawen straightened out the long hair raised by the wind Buddha and said: The construction of this kind of circular city began in the Ming Dynasty. Before the Ming Dynasty, it was a wild place, and there were many bandits and bandits, in order to prevent bandits and bandits from robbing. Our ancestors used this "barrel city" for defense.

This kind of city is much higher than the city of the Central Plains generation, mainly because Yungui is a mountainous area, and if the city wall is not high enough, it is very easy to be attacked from the mountain later. And this circular structure is also much stronger than a square city, which should be the effect of the pulling force referred to in physics.

The "Barrel City" has five gates, three of which are dead doors and two are trap doors. The southeast and southwest are called the trap gates, which are convenient for entering and exiting at ordinary times, and when there are bandits, they only need to guard these two gates. It can greatly reduce the number of defenders.

The southeast side is the street downtown area, which is a place for shopping transactions; In the southwest is the ancient Yamen, which is equivalent to the current commercial center and administrative area. There are three gates due east, west, and north, which are called the Gate of Death. The door of death is usually not opened, and it will only be opened during special periods, such as when the city is besieged, you can open the door of death and make it a trapdoor.

Due east and due west of the two dead gates can lead to the mountains and transport grain. Even if the city is besieged, the mountain people in the city can enter the mountain through the east and west gates to hunt. If the unfortunate city is broken, you can escape through the north gate into Wuyun Mountain, Wuyun Mountain is unpredictable, if no one leads the way, the bandits rush in, I am afraid that it will be difficult to retreat.

After listening to Zhao Yawen's speech, Cheng Yifan secretly admired the wisdom of the ancients. In the era of cold weapons, this is an iron bucket city that is easy to defend and difficult to attack.

"I once heard my grandfather say that the locations of these five city gates are arranged according to the five elements of the direction." Zhao Yawen continued.

Due north Gao family Jin Zhen guards the north gate, east Ye family Tu Zhen guards the east gate, West Gate Jin family Shui Town guards the west gate, southeast Li family Huo Zhen guards the southeast gate, and southwest Zhao family Mu guards the southwest gate.

"What's the mystery in this?" Cheng Yifan asked curiously.

"I don't know about this, maybe it's something like mutual restraint, right?" Zhao Yawen shook his head and replied.

Gao Yunliang on the side sighed at this time: "It's a pity that Lao Zhao didn't come!" If he's here, he might be able to see something. He once told me that not only these five cloud towns, but even these five cloud mountains are made up of a combination of yin and yang and five elements. ”

"Oops! Yun Liang, Zhao Shenghua, her surname is Zhao, and she also understands the five elements of yin and yang, so she won't be you Wuyun Mountain people! Cheng Yifan shouted as if he had discovered a shocking secret.

"I also thought about it, but Lao Zhao said that his ancestral home is Beiyang, and he also moved from the Jiang Death area. And our Zhao family in Wuyun Town has not heard of a branch out of the mountain, so it should be unlikely. ”

"Perhaps...... Maybe the ancestor of the Zhao family is already a bull-nosed veteran! Hahaha......" Gao Yunliang laughed.

Zhao Yawen also laughed, and slapped Gao Yunliang with a fist dissatisfied.
