Tours is also worthy of the leading master craftsmen in the smelting area, and the nails produced are almost exactly the same as Shu Han's imagination, after Shu Han looked at the samples, and obtained the approximate parameters of these nails from Tour's mouth, such as hardness, flexibility and other values, of course, because of the lack of measurement tools, most of these figures are inferred from his experience.

However, Tours has pondered for decades in this way, although the numbers cannot be 100% accurate, but the error will not be too large, and for the data that Tours said, Shu Han is undoubtedly satisfied, he immediately said: "Make a thousand pieces first, try it, if it is not good, then change it, what do you think?" ”

Because these spikes are consumables, colliding with rocks, it will naturally cause damage, a thousand sounds like a lot, but if you really use it, it is not enough for a few days in this large mining area, Tur has no opinion on this, he said generously: "It's all up to you, you can say as much as you want." ”

After solving the problem of tools, Shu Han finally finished the day's work, he couldn't wait to return to his dormitory, and didn't even participate in the dinner of his colleagues, so he went to the room, picked up the book he bought, and looked left and right, how to see how he liked it.

Just fourteen books, costing him thirty-seven gold coins, of which the book "Near the Black Iron City, Left Fourth Ruins-Left Seven Ruins Essay Examination" accounted for nearly half of the funds, Shu Han finally understood what kind of concept Zhao Qingtian's mouth was compared to the gold relics book, since this book was the most expensive, Shu Han directly put the other books on the shelf, picked up the book first, and began to read.

According to the records in the book, these four ruins are the largest in scale and the most detailed in content, and the items excavated from them have never been rich, so they have been studied in the most depth by the majority of scholars, and these four ruins are well-known up and down the Black Iron City, so these materials are relatively easy to obtain compared to other ruins information.

After all, they are very famous, and the needs of readers are naturally great, and the benefits of transcribing these papers and articles are also great, and the logical relationship between them is simple and clear, and other books, Zhao Qingtian tried to buy them, but obviously they can't be obtained in a few days, and this set is undoubtedly the most common ruin-related books in the black market, even so, the price is still expensive.

The book is divided into four chapters, the first chapter is about the ruins themselves, the second chapter is about the cultural relics and documents found, the third chapter is about the role of these cultural relics and documents, and the fourth chapter is about the literature and philosophy in the ruins.

Schuhan begins with the first chapter, which describes the exact location of the ruins and how they were discovered, followed by the general distribution and shape of the ruins, and then speculates about them, in which one of the authors points out that this may have been a densely populated place in the center of a city during the Pastoral Era, and that the reason for this speculation is that the number of artifacts found here is much greater than elsewhere.

At the same time, according to the study of the remains of the building, it was found that the buildings here are generally more than 70 meters, and there is a building with a height of more than 200 meters, which is located in the fifth area on the left, about one kilometer away from the fourth left, which is the largest single building found in the archaeological community today, so it is judged that the location of the fifth on the left should be the center of the city in the pastoral era.

For this judgment, Shu Han basically agrees, in modern times, a high-rise building of about 200 meters may not be anything in a big city, but in a small city, it can definitely be called an indicator building, but Shu Han is still not sure, where is this, so he can only basically agree, maybe this is Huhai? Even in the suburbs, two-hundred-meter buildings can be seen everywhere.

After that, there were some inferences, Shu Han didn't look carefully, he was not interested in what place this used to be, and after reading it in a hurry, he turned to the page where the cultural relics were unearthed, which is the key to Shu Han's ability to judge history, but unfortunately, these papers and articles have only words and descriptions, but there is no picture at all, which makes Shu Han very disappointed.

If you can see the picture, Shu Han will be able to determine the era of the destruction of the world on the spot according to some clues, but unfortunately, the whole text is all text, not a single picture, which makes Shu Han's research enter a dilemma, fortunately, these future people are not completely unknown to modern times, and the human beings who survived the disaster still have some basic common sense.

For example, knowing the computer and knowing what an airplane is, there will be no scenes where an iron bird is used to describe an airplane, a supernatural power is used to describe a computer, and a unicorn is used to describe a giraffe, which makes Shu Han at least understand what the authors of these papers are talking about, so that he will not be unable to understand it at all, but also guess.

But these future people, although they probably know the names of some objects, but as for how to use them, it seems that they have gradually forgotten with the departure of their ancestors, so they may know from their ancestors what these relics are called, but what they are used for, no one knows, just like the oracle bone inscription that has just been excavated, people know that it is a word, but how to pronounce it, what does it mean? Nobody knows.

This makes them guess about these things, and the actual role of this thing is completely different, for example, the computer, in the eyes of the author of this paper, is a makeup box, and he is also very rigorous certification, why is this a mirror, first of all, a screen is used to see themselves, the speaker is used to store jewelry, the keyboard is used to determine the makeup, as for why there is no one now, it is because the glass on it has been oxidized, so it has lost its effect.

There are also headphones, for example, in their explanation, their function is earbuds, which are used to prevent sound from entering the ears, which is not wrong, but it is a little far from the actual use, but this can't be blamed on them, after all, these things are buried in the ground, I don't know how many years, the parts have long been damaged, and there is no repair in this era, so naturally it is useless.

However, according to the excavation of these cultural relics, Shu Han can at least get a definite answer, that is, the modern destruction time should not be too far from his own era, because among these cultural relics, there is nothing that he cannot understand.

This made Shu Han worried, he originally speculated that the time of modern destruction would be at least fifty years, or sixty years later, but if this is really the case, then according to the theory of the Big Bang of science and technology, at that time, not to mention whether controlled nuclear fusion was born, at least new materials should be initially applied, and new materials will inevitably drive the development of other industries, such as electric vehicles, super charging pumps, but according to the cars in the ruins, most of them are gas bullet trains.

This shows that the era of destruction should not exceed twenty years, or even ten years!

This result made Shu Han a little unacceptable, such a recent time shows that his parents and friends are very likely to experience this catastrophe! This moment made Shu Han's consciousness blank for a long time, which was a result he never expected.

"How so??" Shu Han muttered, he only feels that everything is terrible now, and his situation in this world has improved a little, but he didn't expect that now his current life seems to be about to suffer, looking at the books in his hand, Shu Han's original vigorous desire for knowledge is gone at the moment, he is a little afraid to continue to turn it, he is afraid that in the later literature, there is an exact year, if it is the beginning of 202, Shu Han almost dare not imagine, what kind of situation it will be.

Shu Han hurriedly closed the book, and the person lay on the bed, as long as he fell asleep, everything would be over, yes, these are just his own conjectures, what is it? Although there are many bad things and many bad things in modern society, it is far from collapse.

The environment is polluted, it is true, but these pollution are still controllable at least now, and all countries are trying to reduce emissions as much as possible, and the environment will definitely get better and better in the future.

The haze of war is indeed there, but most of the wars are regional wars, and there is no direct conflict between the major powers, which is also a fact, and a nuclear war will break out within ten years? How is this possible.

What else could lead to an outbreak? Great earthquakes, great ice ages? This should also be impossible, there is a certain law to follow in geological movements, if there is really a huge earthquake, ten years ago, twenty years ago, didn't you feel it at all?

Or was it a great plague that took it all? The more Shu Han thought about it, the more scared he became, the more he thought about it, he straightened up from the bed again, looked at the book on the desk opposite, and felt all kinds of torment in his heart, and finally, he decided to get up from the bed and sit in front of the book.

"I can't solve the problem without looking, I have to watch, I have to know the truth." Shu Han trembled and said to himself, the book in front of him seemed to be no longer a simple academic paper, but a book of fate involving life and death, just a simple action of opening it, Shu Han did it with great difficulty, as if this book had the weight of Mount Tai.

"Laptops, smartphones, iPad scraps, it's really not much different from modern times." Shu Han was frightened, he continued to turn back, and soon the page of cultural relics had passed, and then there were documents, but unfortunately, for more than two hundred years, these paper documents buried in the ground had already become fragments, only some of them survived, but the handwriting was also blurred, and there were very few records on these papers.

But there are still many very important things in these documents, such as the name "Hai'an", which appears in many documents, and people here understand him as a place name, but Shu Han knows that this is the city where his modern home is located, and this is the remains of Hai'an City!
