The old man Xun said and lifted the glasses that were about to slip off the bridge of his nose, Xun An on the side saw him licking his lips, and pushed the water cup on the side of the table, which was a bamboo tube-shaped water cup, and there was a bamboo forest pattern on it, which was quite elegant.

"Hehe, I bought it the day before yesterday, it looks good, take it back as a souvenir. ”

Noticing Tang Qing's gaze, Old Man Xun took the time to say, The topic was far away for a while, "You can also buy some souvenirs, don't you young people like to buy and buy, I think many things in this city are very good..."

Tang Qing looked at the pile of case files in his hand, aren't they reasoning and discussing now? What the hell is it to buy souvenirs?

"Oh, old man, you go on, I'm listening. Du Yeshen urged, "Tell me what you have found, what is the glorious history of this city?"

"History......"This is considered to ask the old man's business, and the old man Xun is still holding a bamboo water cup in his hand, and said, "This city is a town guarding the city. ”

Seeing Du Yeshen and Tang Qing's puzzled expressions, he explained with a smile: "You always know what this 'town guard' means, in the past, our country still had this kind of official position, such as so-and-so town guard envoys and the like, but they are mostly military attachés, civil officials, and there are also, for example..."

Seeing that the old man was about to make a tirade, Du Yeshen was a little anxious again, and interrupted the other party's words, "Old man, let's stop talking about this history, let's talk about this city first? I can't even recall how I passed the history exam in the first place." ”

Du Yeshen's complaint can be said to be deeply popular, Tang Qing saw Xun An on the side nodded subconsciously, reacted and froze, looked left and right, and looked at Tang Qing's smiling eyes, his face was slightly red, and he was finally not a cold-faced handsome guy.

"Okay, okay, let's talk about this city. Old man Xun is not engaged in education work, smash it, smash it, drink two more sips of water, the topic turned back, and said, "This town guard is generally according to our understanding of the meaning of garrison, not much difference, and then there is the meaning of suppressing and guarding against the people of their own or foreign races, the place where it is guarded is a place where chaos often occurs, and the same is true here, this city is to guard the black soil." ”

Xun An probably hadn't heard the old man say this, showing a puzzled look, the old man Xun glanced at him, and continued: "This is not a history with us, I probably took a look, the two sentences at the beginning of the book "Shou Shanzhi" are very interesting, it is the order of Emperor Xiao to build this town to guard the black soil, this Emperor Xiao vaguely said that it seems to be a very famous emperor, but what exactly he did, it was not mentioned in the book..."

Old Man Xun's tone was full of regret, for a person like him who has studied history all his life, whether it is from his own country or from another country, he will have an idea of eagerly wanting to unveil the other party, even if it is only a corner of what can be glimpsed, it will make him sincerely happy and feel that his existence has value.

This sense of accomplishment shows that he loves history from the bottom of his heart and loves the process of discovering certain facts from history.

"I don't know what this black soil is, looking at the meaning of the book, it seems to be an extremely important existence that belongs to evil, according to my speculation, using good to suppress evil, it seems to be no problem logic, so it is conceivable that the important mission of this city after it was built is to suppress the evil of the black soil with the good of a city. ”

There are still some doubts in Old Man Xun's words, but this formal thing has been made clear, good suppresses evil, this is no problem.

The question is how can they manifest evil as black soil in this time and space, or how do they judge that black soil is evil, and what is this black soil, the real black soil?

Probably having seen too many weird and secretive, Tang Qing felt that he could understand this passage that the other party said and felt a little inexplicable, some of the concepts that many people thought were formal could really be manifested as a certain existence, such as fear, which could be condensed into beads that could be touched in reality, and so on, other emotions, not even emotions, just some kind of concept, could also be condensed, or simply refracted into a specific existence.

Black soil can be black soil, or it can be the concrete form of evil.

Like Shoushan, is this huge city really a real city? Or, is this city a concrete form of existence transformed by some goodness, so that it can be expressed in the form of a city, which can be touched, seen and spoken.

"It's too abstract, aren't they... Isn't it really superstition?" Du Yeshen has accepted atheism since he was a child, and this kind of thing used to be summarized as superstition, but in this city, although he has not seen all the weirdness, he has already found something abnormal, and he did not directly deny it, but raised questions.

"True or false, since the book says so, let's first accept it, understand it according to this condition, and then analyze the reasonableness and unreasonableness, the reasonableness under the current conditions, and the unreasonableness under the present conditions. ”

What Mr. Xun said is not too profound, this is an attitude of historical research, just like many historical books say that there is a certain god, of course, modern people can scoff at it, saying that there is no god at all, but do not accept this concept first, how to understand their speculation about God, and how to understand their behavior according to this kind of speculation, the most common is sacrifice, if you do not accept that concept first, sacrifice is not civilization, but barbarism.

This is the process of the development of civilization, from scratch, from coarse to fine, little by little in the course of history to correct certain fallacies, and then produce new fallacies, on the whole, it is still advancing, but this progress is sometimes tortuous, not a straight line.

Just like the cognitive process of people, it is impossible to know where the focus is at the beginning, and then draw a straight line from the foot to the end point, and move straight forward, there is always a process of confusion in the middle, there is always a choice of path, and some choices do not point to the end, it is likely to go around in a circle and return to the original point and start again.

Some simply take a fork in the road and then lead diagonally to that end from another angle, or simply open up a new path to another end.

This is true of one person's choice, but what about many's choice?

The mysterious charm of history lies in this, which is the result of many people's choices, in which the positive and negative, the positive and negative, and finally what comes out is the history that people can see now.

Studying every detail and savoring every event in it, it seems that you can see those points of wisdom shining in a brilliant starry sky.

Behind the lenses, there seemed to be infinite starlight in Old Man Xun's eyes, and he continued: "Because many places are not clear, and I can't make out some words, I can find more evidence from these case files, at least speculate how those who were relocated developed to their current situation, and what happened..."

The words suddenly broke off here, and Du Yeshen listened attentively, and asked, "What happened?"

Old Man Xun shook his head with a smile, didn't continue, and said, "How were you in the city these two days, did you sleep well?"

"Okay, these days, I finally feel the benefits of going to bed early and getting up early, I just feel that my body is healthy, and it's good to travel and relax from time to time. The biggest advantage of Du Yeshen is that he will not continue to get to the bottom of things when he sees that the other party doesn't want to say it, and he has the kindness to understand other people's little secrets to the greatest extent, so he changed the topic and talked about the benefits of travel.

Tang Qing, who had been silent, shook his head at this time and said, "Don't dare to sleep." ”

Du Yeshen turned around in surprise and glanced at him, because of the principle of "keeping good" in this city, he knew that the other party was telling the truth, but why didn't he show anything on his face, if he didn't sleep well, what about the dark circles under his eyes?

"I saw this, what does the old man think?" Tang Qing pushed through the two books and nodded on the words "red light" and "night fog".

Old man Xun held the frame in one hand, as if he wanted to find a more suitable angle, looked at it carefully, and then looked at Tang Qing, the smile on his face was more than two points of praise and joy, Du Yeshen was a step behind, he didn't see what it was, seeing the old man's smile, he also knew that there must be something wrong with it that he didn't find, and stretched his neck, trying to see more clearly.

"The people in this city are said to have specially migrated, and they are all the kind that are known as the so-called ten generations of good people, how do they verify it, don't say, anyway, after coming here, it was peaceful for a while, until the next generation appeared... From the records I have seen, the number of cases is gradually increasing, and the date is getting closer and closer..."

The smile gradually disappeared, and when he said this, Old Man Xun looked at Xun An with a more complicated gaze, as if he was guilty, probably because he was afraid that he would drag down his grandson.

Tang Qing also discovered this, the case files are arranged according to the date, and it is easy to make it clear at a glance, and this is also easy for people to speculate.

Not to mention the injuries and deaths, the gradually dense disappearance cases -- how many days and nights can hundreds of thousands of people withstand, and how many fog engulfing them?

What kind of alienation is the specifics, and how to maintain the rules of "keeping goodness", it needs to be further understood, what we have seen so far, is not optimistic, and the people in the city are still not people, whether they were the original people, it is very doubtful.

Did they come to some fragment of the city's history, or did they come to some strange place after the alienation and destruction of the city?
