Lu Qiao naturally knew what was going on and lighted his head. Dahai said at this time: "How much do you know about the Devil City?"

When Lu Qiao heard Dahai say Devil City, he understood that this might be the ruins to go to.

Luqiao's mind was spinning wildly. The Devil City, also known as Urhefeng City, has a strange shape. The locals and Mongolians called this city "Surumuhak".

This is a thought that flashed through Luqiao’s mind. Isn’t that thing a scenic spot?

Or is it the same name different place?

The waiter smiled and said, "The ten or eleven of you came outside are asking about that place. Thirteen of you plan to go to that place the next day. There is nothing good to go there, I advise you not to take risks."

"If you persuade me, you have to tell me the reason, right?" Dahai asked.

"We don't know what the place was originally for. Later, the ancestors regarded it as a place to worship their ancestors. It was still the village or the village was not a town. As long as there were respected people in the village, they would be sent to wherever they died. Maybe there were too many people dead, and the whole city would be covered with faint blue fire at night." The waiter explained.

"Phospheric fire, phosphine. The flame during combustion, when phosphorus reacts with water or alkali, produces phosphine and a small amount of phosphorus pentoxide. It is a colorless gas that can be spontaneously ignited. The phosphine decomposed when the corpses of humans and animals decay and spontaneously ignite. The white blue-green flames that are sometimes seen in the wild at night are phosphorus fires." Wusu immediately explained.

"You said it more scientifically, but I understand it was Phosphorus Fire. But people at that time didn't think so, so they named the Devil City. The Devil used flames to remind us not to transport the corpses in. So since then, the entire Devil City has become a forbidden area." The waiter explained, taking out a cigarette and smoking it in the room.

Seeing the other party smoking, Dahai coughed and took out another five hundred and gave it to the waiter: "I hope you won't go out and talk nonsense about what you are talking about today."

"Of course, I know a lot about you outsiders. It is not a good thing for me to be too close to you, so I will leave, but I will advise you again: Don't go into the Devil City." After saying that, the waiter took a cigarette and left quickly, opened the door and left with his waist.

Seeing that there was no foreigner, Dahai stood up at this time: "In 1999, the country developed rapidly. I began to learn to do documentaries abroad, and there were countless pictures of the great rivers and mountains in China. However, our college was not archaeology, but the director and tourism department were arranged to go to the northwest to shoot. The tentative one of the first was Urhe Fengcheng, but the name was twisted and we called the Devil City as the favorite in China. In that era, navigation was restricted, and after reaching the approximate location, we could only ask each family. As a result, we came here by chance. After coming here, we did not disappear but saw something amazing."

"The forbidden area of ​​our own town is not from outsiders. So it's normal, but I don't know what you call awesome things." The waiter heard the version described by Dahai at this time.

Dahai explained: "The directors and those who are engaged in tourism naturally don't know what they see, so they quickly called the archaeology student. The people who went there were your parents. Do you understand what happened next?"

Lu Qiao lit his head: "What is such a terrible thing?"

"The top ten secret techniques in China are: divination, talismans, dream interpretation, formation, calendar, Taiyi divine numbers, Daliuren, Qimen Dunjia, astrology, and Feng Shui." Dahai spoke.

"What are you talking about this?" Han Dong asked.

"There are traces of Qimen Dunjia in the former site of this Devil City." Dahai explained.

"What is Qimen Dunjia?" Chen Hao asked in confusion.

Wusu quickly explained: "You should know that the world's number one skilled craftsman is called by two people together, right? Lu Ban, the founder of Chinese architecture, and Mozi, the founder of the Mohist school. Qimen Dunjia started with only a metaphysics, which was explained like astrophysics. Improving by the Mohist and Gongshu descendants is equivalent to bringing physics into practice. It is equivalent to going from Newton's laws of physics to the invention of cars and planes. This is the modern Qimen Dunjia. But we really don't understand that Mozi and Lu Ban were the vassal states of the Zhou Dynasty in China, the capital was Qufu, and the sphere of influence is today's Shandong, southern Shandong, and central Shandong. But why did their ruins appear in the desolate northwest?"

Wu Su said here and took out a few black and white photos. Lu Qiao and others looked at it. The photos contained all kinds of tools: saw, curved ruler, ink bucket, cloud ladder, hook strength, stone mill, lock key, paper umbrella.

"No way? Are there these things in the ruins?" Lu Qiao looked at the old photos in disbelief.

"I majored in history. I have verified many things. But I have not got a definite answer. What I can understand is that I was exiled to the frontier. In the Lu State, many people were educated and lighted punishments. Therefore, when encountering a great evil person, they would not be punished. Exiled to the frontier labor is the longest thing to do. If this seems to be the case, then the descendants of the Mohist and Gongshu will inevitably be punished for fighting and were punished to desolate areas of the frontier, right? " Dahai explained.

"You said it is not impossible, but I have the opposite opinion here. In ancient times, the frontiers were indeed exiled to participate in the construction of the frontier. But in fact, I have studied your statement over the years. In ancient times, there were five levels of exile, Lu as an example. His left and right countries were Qi, Wei, Song, and Chang. Although there were coastal areas, we could not bypass Wei and sent to the frontier, right? Then, from the way to the farther, we should be unmanned coastal areas, 2,500 miles of frontiers, 3,000 miles of remote areas, 4,000 miles of smoke and smoky areas, and the farthest extreme border areas. According to your statement, the farthest extreme north may be the frontier, but when applied to the Lu Kingdom, you cannot reach the frontier." Wusu explained.

Dahai shook his head: "I can't tell you about your accomplishments in archaeology. But I want to tell you that according to the logic of archaeology, you are right, but if you look at the historical level, no one unified China during the Spring and Autumn Period, and there was no external chaos because of the construction of the Great Wall. The frontier was to build the Great Wall. If you look closely at this generation, you happen to be the edge of the construction of the Great Wall. Of course, you are studying archaeology and focus more on scientific research rather than history. So Professor Wusu, I don't think you are wrong here."

"The research object of archaeology is archaeological sites, and the basics of history are the official system, historical geography, chronology and cataloging. The two are very different, and there is one thing in common: they often need the other's knowledge but look down on the other party." Lu Qiao added.

Lu Qiao tried to make fun of it, and naturally he didn't want Dahai and Wusu to have arguing here.

Chen Hao and Han Dong from two other disciplines smiled awkwardly: "Then the matter will be explained."

"Then let's talk about it here. We must go to this Devil City tomorrow. In addition to the investigation, we also need to find out more than 30 missing people." Dahai explained.
