"Mr. Cai, I have specially put a large oilcloth under this straw, and the hole below must be intact."

A farmer-like man who accompanied him flattered Cai Zhongtang and said that he was Liu Dachun, the owner of this farmland, and the Cai family had given him a large sum of money to requisition here, so he had always been very concerned about this matter.

"Don't worry, you won't be lost when the time comes." Cai Zhongtang said lightly, a look was transmitted, several Cai family men suddenly understood, and moved the straw on it together, and after a while, a large piece of oilcloth was exposed on the ground, a large piece of depression in the middle, and a dark and secluded hole below.

"Old Five, you and Liu Dachun are staying here, don't let people approach. If...... If we don't come out before tomorrow morning, you can send the news back to the family, and then Yaqiang (Cai Yawen's second brother) will know what to do. Cai Zhongtang commanded a man, his words still full of worry.

The fifth nodded in agreement, looking around with a wary face.

"Chen Zixuan, this is an oxygen cylinder and a gas mask, you wear it well, you can't panic if you encounter anything below."

Cai Yawen reached out and handed me and Longzhu the equipment for the trip. Although the Cai family is engaged in the business of inverted fighting, unlike those tomb robbing schools that have been handed down into a system, the Cai family is a monk halfway and has no inheritance, so they basically do everything they can, using a lot of high-tech means, including gunpowder, bombs and the like. I even heard Cai Yawen say that several years ago, when they were excavating an ancient tomb in the southwest, they also used an excavator or something, but then they stopped because they attracted the attention of the government.

"Master Wang, this time I, Cai Zhongtang, cheekily invited you over, also to save my eldest brother. You are a respected veteran in the entire Sichuan cultivation circle, and your knowledge is extraordinary, please be sure to do your best to help, after the matter is completed, our Cai family will definitely repay the gratitude! Cai Zhongtang said to Wang Yifeng, his expression sincere.

Wang Yifeng waved his hand and said: "No need to do this, the old man is also quite interested in the royal city of this ancient Shu Kingdom." And my apprentice, I also have a good impression of your little girl, hehehe, the two juniors are about the same age, I think they should be close to each other. ”

Wang Yifeng's simple words made Cai Yawen's face change suddenly, as shrewd as her, how could she not hear the meaning of Wang Yifeng's mouth, and glared at Liu Zelong viciously at the moment, her face was very ugly.

"Yo, does this little girl have any opinion on the old man's words?" Wang Yifeng was still smiling, but his eyes were much colder.

Seeing this, Cai Zhongtang hurriedly said: "What Master Wang said should be, I think Liu Zelong, this little guy is also good, and the two can have more interactions." ”

Just when the Cai family was talking to Wang Yifeng, I walked to the entrance of the cave and looked down the dark and secluded hole, which was made out by the Cai family with a drilling machine some time ago, and after reinforcement, the connection with the dungeon was opened, and finally the manual excavation was used to slowly advance.

"Wear your mask, the air down there doesn't smell good." Cai Yawen walked up to me and reminded me and Longzhu.

I nodded, and after reaching out to help Longzhu put on the mask, I got myself again, and the mask was connected to the concentrated oxygen on my back, which could provide people with breathing for a long time.

Everything was ready, a man of the Cai family took the lead in sliding down the hole after tying a safety rope around his waist, these guys are all trained by the Cai family to specialize in inverted buckets, and they are very skilled in their techniques.

After a while, the bell on the rope rang several times in a regular manner, indicating that the fellow had reached a safe place, and that everyone could go down.

"Let's go! Longzhu followed me, don't panic on the road. Cai Yawen saw that the rest of the people had entered the cave, and after saying a word, she also slid down.

Longzhu and I followed, the slope of this tunnel was slightly steep, and under the action of gravity, the body fell involuntarily, frightening Longzhu in front of him to scream again and again.

I don't know how deep this tunnel is, anyway, I feel like it has been a long time, if it weren't for the thick leather armor on my body, I'm afraid it would be worn out directly.

When we fell back to the ground, I couldn't help but breathe a sigh of relief, this place can only have a sense of security when we are down-to-earth. I looked at the surrounding environment, there was damp mud up and down, left and right, this place should still be a tunnel dug by the Cai family, narrow and crowded, everyone can only hook their waists to move forward. But it didn't take long for the ground under our feet to dry out, and there were still some artifacts made of stone or bronze on the way, indicating that there had been traces of human beings in this formation.

However, when I went underground, I suddenly remembered a very serious problem. It's a buried human city, but it's not like a normal tomb.

For the tombs, because there are underground palaces and burial chambers to support them, it is possible to ensure that the contents are not buried by crumbling earth. But the city is different, there is nothing to cover above them, as the landscape changes, the ground subsides, and the earth will bury the whole city together, just like Pompeii in ancient Rome.

Xue'er seemed to sense my thoughts, and whispered: "Don't worry, this place is different from what you imagined, and it will be clear when you see it." ”

I felt a little at ease, but my suspicion of Xue'er became more and more intense, this girl seemed to know everything, this buried deep underground Qushang City Ruins Xue'er actually came more than three hundred years ago, and ......

At this moment, Cai Yawen and Liu Zelong and others in front of me all let out an exclamation, I was taken aback, and hurriedly followed, seeing everything in front of me by the light of the flashlight in their hands, and I couldn't help but let out an exclamation, because the things in front of me were too unexpected.

This is a city built underground!

In front of us were stone buildings, densely packed with buildings that stretched for a distance, and I opened my eyes wide to see a huge palace complex at the end of these houses, which I couldn't see because of the distance, but it still gave me a very grand and spectacular feeling.

Above the city is a world of stalactites, the top walls of the white caves are covered with all kinds of stalagmites, stone pillars and stalactites, and there are large and small karst caves in the mountains around the city, they are far away and deep, and they do not know where they lead.

"Karst landscapes!"

I couldn't help but exclaim that this was not the buried ruins of the city I imagined, but a human city built in a large underground cave.

In geology, karst landform refers to the long-term erosion and erosion of soluble rocks by water flows, which corrodes them completely, thus forming large hollow karst caves underground. As we all know, China's karst landforms are very widely distributed, but they are mainly concentrated in the Yunnan-Guizhou Plateau and the southwest of Sichuan, such as the Jiulao Cave of Mount Emei is a very famous large karst cave.

It's just that what I didn't expect was that the legendary Qu Shangcheng, the royal city of the ancient Shu Kingdom, would be built at an unknown distance deep underground, which is really incredible. Could it be that the ancient Shu people found this place along the karst cave on the surface, and then transported the materials in to build it, such a project is unimaginably grand!

I was not the only one who was amazed, but even the well-informed Cai family was amazed again and again, and they couldn't believe everything in front of them.

"Second uncle, how could this place be said to be a cemetery in the first place, can't they even tell what this city looks like?" Cai Yawen asked first, her face was extremely unsightly.

Cai Zhongtang explained: "They can't be blamed for this. At that time, the eldest brother personally led the team, and after opening the tunnel, he personally led people down, and the people above did not know the specific situation. It wasn't until later that the signal from above received a signal from the ground and the rope was hoisted up, only the unconscious eldest brother and the others were all gone......"
