The Unrivaled Tang Sect: The Copper Coffin

This is the first time Jiang Hai has been late, or can be considered absent from class.

Making the Silver Dragon Sword had taken him so much energy and time that he suddenly forgot about time. In the past, he had never skipped class or been late. It was for this reason that Mujin did not punish him.

After practicing in the afternoon, Jiang Hai went to the Soul Guidance District Library as usual and borrowed a lot of books related to materials. The librarian had long been accustomed to this. This kid would borrow them in two days. A batch of books seemed to have been purchased from him. He must have borrowed hundreds of books from the library. With so many books, he couldn’t read them all even if he stayed awake. He shook his head. Maybe this kid acted out of his own way on purpose and wanted to attract other people's attention and attention?

In the office of the director of the soul guidance area, as always, the list of books borrowed by Jiang Hai appears on his desk every day. At first, Qian Duoduo paid attention to it, but later on, Qian Duoduo became accustomed to it. Is Jiang Hai a genius or a sensationalist? The truth will be revealed one day, but Qian Duoduo still prefers the latter.

He also knew something about Jiang Hai's daytime courses. In addition to the eight hours of courses and normal rest and practice time, Jiang Hai also had a few hours to read. Even if he read, how many hours could he understand all the books? Qian Duoduo understands that soul guidance is a practical knowledge, and it is far from enough to work behind closed doors.

After reading the book catalog that was completely different from the previous one, Qian Duoduo smiled to himself and said: "This kid has been reformed now. He knows that the soul guidance formation method will not work. Now he has begun to study the materials, and he is also right. , Materials are the basis of everything. Read more books about materials. Even if you can’t find anything in your research, you can still lay the foundation!”

Qian Duoduo is the deputy dean of the Soul Guidance Department, the dean of the Soul Guidance Department Xian Liner and the intended successor. One is dedicated to leading students, the other is devoted to studying soul guidance tools, and the entire inner and outer affairs of the Soul Guidance Department have fallen into place. Qian Duoduo had to deal with a lot of things in a day. Jiang Hai just subconsciously paid attention to it. After smiling, Qian Duoduo stopped paying attention and concentrated on handling his own affairs.

After Jiang Hai made the Silver Dragon Sword, he didn't slack off at all. He returned to Poseidon Lake with a somewhat thick material book and started researching and learning in the copper coffin.

With the divine fire swaying, Jiang Hai quickly flipped through the books that recorded the materials, but he was not satisfied. The books that recorded the materials in this world were all too general.

The next day, Jiang Hai borrowed a batch of books again.

The same happened on the third day...

The fourth day, the fifth day...

On the seventh day, Jiang Hai's eyes lit up. Since he couldn't find a material book that he was satisfied with, why didn't he compile a new material science book? What you see on paper is ultimately shallow. Didn’t you already understand this principle before you knew you had to practice it? The Silver Dragon Sword is an excellent example.

Thinking of this, Jiang Hai just did what he said. He took out a thick leather book and wrote the three words "Materials Science" on the cover. Nothing could summarize the book he wanted to write better than the three words "Materials Science". In the signature column, Jiang Hai did not use his own name, but wrote the words "Bronze Coffin Research Institute".

In the book "Materials", Jiang Hai plans to integrate all the materials in Douluo Continent with metallic materials, non-metallic materials, and composite materials, and the first one is metallic materials.

In the past few days, Jiang Hai has read countless materials-related books in his mind. Liuli Xinjing summarized the statistics and recorded 1,309 kinds of metal materials. However, excluding alloys, they should be classified into composite materials. The remaining There are more than 500 kinds of metal materials in the world. I have to admit that the types of metal materials in the Sun Moon Continent and Douluo Continent are really too rich. Therefore, even if you don’t have to do too much research on materials, the materials that exist in nature are also It's enough for the soul engineer to make soul guidance devices.

He wrote the names of all 517 metal materials on the cowhide notebook. There was a large blank space behind each name. Although he knew the uses and properties of many of these materials, Jiang Hai had no idea about Douluo Continent Soul Master. The world has no hope of understanding the material. If he wants to write, he must write an absolutely accurate book. The contents of other books can be used as a reference, but there is no need to follow it as a guide and lose his own thinking.

He plans to explain a material from multiple aspects such as heat, mechanics, electricity, magnetism, optics, chemistry and soul guidance. This is also the foundation of real soul guidance science. If this book is completed, it will change the soul guidance. The foundation of the world, but the difficulty of this book is unprecedented. Fortunately, there is a glass heart mirror, which can reflect most of the materials, making the research much easier.

After metals, come non-metals, and most of the non-metallic materials on Douluo Continent are natural crystals, agate and other jade. These materials also have extremely excellent soul-guiding properties and are indispensable materials in the manufacture of soul-guiding devices. More are used to depict core formations, totaling more than a hundred types.

Then there are alloys and other composite materials, a total of one thousand and nine types.

He filled in the names of all the materials he knew, and there was a lot of blank space behind each material and three categories to add new materials that he would come into contact with later.

This was a big project. After all this was done, it was already the early morning of the next day. There were thousands of materials, one of which almost occupied a page. What appeared in front of Jiang Hai was a thick notebook, which was almost larger than the one he had before. All the books I read were much thicker, and looking at this book gave me a sense of accomplishment.

The outline has been established, and the next step is to continuously fill in and improve this book. This will be an unprecedentedly large project that will consume unimaginable time and energy.

A journey of a thousand miles begins with a single step.

After stretching, Jiang Hai yawned and walked out of Poseidon Lake and walked outside Shrek Academy.

Practice brings true knowledge, and if you want to perfect the book "Materials", you need to consume a huge amount of resources and energy, but he doesn't have much money anymore.

Shrek City, Babao Tower.

Jiang Hai came to the shop again. When he saw Jiang Hai, Liu Yun immediately came up to him and said with a smile, "It's you, are you here to buy materials for making soul tools?"

"Hello, I haven't asked you what your name is yet?" Jiang Hai asked curiously as it was fate to meet this girl again.

"My name is Liu Yun, and I am the shopping guide of Babaolou!" Liu Yun said with a smile. She earned a lot of commissions last time she hosted Jiang Hai. There is news from the superiors that they want her to be the lobby manager on the fourth floor. Unexpectedly, I met this young man again.

"Liu Yun, what a name!" Jiang Hai nodded and said, "My name is Jiang Hai, sister Liu Yun. Can I buy a soul tool here? I want to sell a soul tool!"

"Sell soul guides?" Liu Yun was stunned for a moment, nodded slightly and said: "Yes, not just soul guides, if there are other treasures, our Babao Tower will collect them, but soul guides need to go through us The price will be determined after the professional soul masters in the building appraise it. Brother Jiang Hai, what level of soul guidance device are you selling? The prices of different soul guidance devices are also different."

Jiang Hai nodded, indicating that he understood, and said: "What I want to sell is a fourth-level soul tool!"

Researching soul guides requires a lot of resources, and the last time he bought the colorful cloud pattern carving knife and materials, he spent all his savings. Jiang Hai is a person who doesn't like to ask for help, so he would rather sell the ones he refined. The first soul tool, the Silver Dragon Sword, didn't want to ask anyone. If he proposed to study the soul tool, the Shrek Academy Soul Guidance Department might not refuse. Even Ma Xiaotao and Zhang Lexuan would help him, but he didn't. This idea.

The Silver Dragon Sword was just a training piece for him. If it weren't for the problem with the blueprint written by Jing Hongchen, he would not have refined this soul tool. There is no burden to sell it now.

"Level 4 soul guide?" Liu Yun was startled, glanced at Jiang Hai, and after confirming that Jiang Hai was not joking, his expression became a little more serious, and he said softly: "Okay, then please come with me! "

It's not that she has never seen a level 4 soul guide. In the Eight Treasures Tower, there is one level 7 soul guide. A level 4 soul guide is indeed precious, but it's nothing. It's just Jiang Hai's age. He was too young. Even if he was a soul engineer, he would only be selling first-level or even second-level soul tools. He didn't expect that what he was going to sell would actually be a fourth-level soul tool.

He led Jiang Hai to a spacious room on the fifth floor. An old man in his sixties was playing with a carving knife in his hand. There was also a drawing in front of him. When he saw someone coming in, he put the drawing away without leaving a trace. He stood up, coughed, and said with a smile: "It's Xiao Liuyun, what's the matter with coming to my place?"

Liu Yun said respectfully: "Mr. Zhao, this little brother Jiang Hai wants to sell a fourth-level soul guidance device. I will bring him to you to help identify it!"

After saying that, Liu Yun turned to Jiang Hai and said, "Brother Jiang, this is our chief soul mentor of the Babao Tower, Mr. Zhao. Mr. Zhao is a sixth-level soul mentor. There will be no problem with his evaluation."

Zhao Dezhu nodded and said calmly: "Little brother, you are also a soul engineer, right? You sell the fourth-level soul guide for your elders, so take it out and show it to me. My credibility is still good, old man. Yes, after so many years of refining soul guides, you can rest assured of your eyesight!"

Jiang Hai nodded, took out the silver dragon sword that had been wrapped behind him, and loosened the cloth wrapping it. A silver sword light shone, and a silver dragon coiled on the hilt, lifelike, and the sword body was light and thin. The whole thing is extremely harmonious, like a perfect work of art.

"What a beautiful sword!" Liu Yun's eyes were sparkling. Girls all like beautiful things, and there is no doubt that the Silver Dragon Sword is so fancy that it looks like a peerless sword at first glance.

And Jiang Hai is also a good-looking person. In front of good looks, everything else is not worth mentioning.

"Fashionable..." Zhao Dezhu was about to comment, but he saw Jiang Hai gently swinging his sword, and an extremely clear sword cry sounded. Zhao Dezhu's expression changed slightly, and he rushed to Jiang Hai, excited. He said: "Little brother, can you show me this sword?"
