From the day Huan Yin made a bet with Lan Tongtian, he got up early every day and practiced continuously. Of the twelve hours of the day, he spent only one hour sleeping, and the rest of the time was spent studying the art of sword forging.

Huan Yin would look for a large number of classics every day to look through them, because Duan Yun said that materials are the foundation of sword casting, and if you can't even recognize a few materials, then you don't need to talk about sword casting. Fortunately, Huan Yin is now the leader of the new generation of the Infinite Sect, and he wants to look through the classics of the sect, but there is no hindrance, which makes his study much smoother.

However, the more Huan Yin looked, the more he found it difficult to forge a sword. Because there is always material on every book that he has never seen, and there is always an effect that makes him feel novel. Even if two materials are of the same utility, there will be subtle differences between them, and if this difference is not memorized, it is likely to lead to the failure of the final sword.

Huan Yin feels like he is back to the days when he was a child, reading many, many books every day, and every day there are new discoveries and more questions. Although such days are hard, Huan Yin is also happy. Because he has been a lover of reading since he was a child, he was deeply influenced by his father and was full of desire for knowledge.

This day is also an ordinary day, Huan Yin locked himself in the room, and kept looking at the classics on the table. At this moment, his originally empty room was already full of all kinds of classics, and if someone he didn't know came to his room, he would definitely think that he had read like crazy. Because now his room, except for the bed and the table, almost all other places are occupied with books, and I don't know if he has moved a small half of the books of the Infinite Gate into his bedroom.

"Squeak!" the voice became extremely distinct in the somewhat dead room. Huan Yin turned his head to look, but found that there was no figure at the open door.

"Senior brother, are you still reading?" Xiao Tian's voice came from the door. It seems that the books in the doorway were piled up too high, blocking his young body.

Huan Yin smiled, walked to the door and picked up Xiao Tian from the ground: "What's the matter, Xiao Tian, no one is playing with you?" It is now afternoon, and it is also the time that the Sword Pavilion uses to rest on weekdays, in the past, in this time, except for Huan Yin and Li Xianyue who were still cultivating, everyone would do something else. As for Xiaotian, he must have hurried to have fun at this time, after all, he is still a child.

"Well, Senior Sister Li doesn't play with me, Senior Brother Gao is like that all day long, I feel bored. Senior brother, what book are you reading?" It seems that Xiao Tian is too bored because he only has Gao Shan to accompany him all day long.

"Senior brother is reading the classics about sword-forging materials, come, senior brother will show you. Huan Yin picked up the book of "Kyushu Chronicles" he was reading and sent it to Xiao Tian.

"Senior brother, you really work hard. Xiao Tian was a little helpless, he originally wanted to find Huan Yin to play with him, but he didn't expect to be stuffed with a book when he entered the door. Still, he picked up the book and flipped it a few times.

"Huh, how can this material called 'Xuan Snake Molt' be written with unknown utility?" Xiao Tian suddenly pointed to a material in the book, surprised.

Huan Yin touched his head: "The immortal master who wrote this "Kyushu Chronicles", he himself didn't know what the effect of the 'Xuan Snake Molt' was, so he just recorded it without adding annotations. ”

Xiao Tian looked at Huan Yin with a puzzled expression: "This thing, it's easy to think of its efficacy?"

Huan Yin looked at Xiao Tian in surprise: "Xiao Tian, then what do you think is the effect of this 'Xuan Snake Molt'?"

Xiao Tian looked innocent: "I have read in other books that the Xuan Snake is the spirit species of Jizhou in the north, and this kind of snake will only appear in the river desert of Jizhou." Although Jizhou is a cold place, the river desert area is very different, but it is a desert, and the heat is unbearable, so the snakes living there are all fire. Since snakes belong to fire, and the snake is the skin shed by the snake, it should naturally belong to fire. ”

Huan Yin was shocked, he knew all the characteristics of the snake that Xiao Tian said, and he had seen it, but he never thought of starting with the snake to analyze the material. In other words, he never thought about analyzing materials, and before he was blindly memorizing materials, what he said in the book, he felt what it was. But now, he clearly felt that what Xiao Tian said was reasonable.

"Xiaotian, is there anything else?" Huan Yin was a little looking forward to whether he, a junior disciple with a great talent for the way of sword forging, could say something.

Xiao Tian nodded: "Well, since this 'Xuan Snake Molt' is the skin shed by the Xuan Snake, it is also a kind of skin on the Xuan Snake's body." I saw a book that said that although the skin of the snake is soft and can be stretched at will, it is very powerful and difficult to break. Moreover, the higher the cultivation of the Xuan Snake, the tougher the skin. Therefore, using the 'Snake Molt' to cast a soft sword can just meet the needs of the soft sword. At the same time, if you can know what kind of cultivation the Xuan Snake is shedding, it will be better to determine how strong it is, so that it will be more convenient to use. ”

"As for what kind of cultivation the Xuan Snake is, it has actually been recorded in the book, and the characteristics of the Xuan Snake skin shed by different cultivators are different. So in fact, as long as you see the characteristics of the Xuan Snake Molt clearly, you can directly determine what kind of Xuan Snake Molt is in your hand!" Huan Yin looked surprised and took Xiao Tian's words.

"Yes, senior brother!" Xiao Tian was still so naïve, and felt that what he said was taken for granted.

However, Xiao Tian didn't know how much shock he had brought to Huan Yin now. Huan Yin had always memorized the properties of various materials before, because he felt that these materials were the accumulation of discoveries made by predecessors, and they were all knowledge that would be known if they were memorized, and would not be known if they were not remembered or seen. It's just that Xiao Tian's analysis just now made Huan Yin have to clap his hands, because he didn't even know what the effect of the Xuan Snake Molt was in the book, but Xiao Tian analyzed it well.

Xiao Tian didn't know what 'Xuan Snake Molt' was, but he knew about the Xuan Snake, the environment in which the Xuan Snake grew and its own characteristics, so he analyzed the characteristics of the Xuan Snake Molt like a bypass, and even how to use it He also explained it in one word.

Huan Yin knew that what Xiao Tian said was right, whether it was the characteristics of the Xuan Snake Molt or its use, Xiao Tian was not wrong. He suddenly felt that perhaps the study of materials could not only be through memorization, but also through analysis.

Analysing the various properties of a material and then derising what it does and how it can be used may sound ethereal, but it is doable. Moreover, the clearer the understanding of the relevant properties of the material, the clearer the grasp of the material.

Huan Yin has read a lot of classics these days, but some of these classics tell about the climate distribution of various parts of Kyushu, and some talk about the changing environment of various parts of Kyushu. Although Huan Yin felt that these things had nothing to do with sword forging before, he still skimmed through them. It's just that now it seems that these contents recorded in the classics are as useful as those that specifically talk about the materials used to forge swords, because Huan Yin can analyze them. As long as he knew enough seemingly mixed knowledge, he could derive the properties of many materials that he had never seen before.

Huan felt that Xiaotian had inadvertently opened a new door for himself on identifying materials. Through this door, he can make use of all the miscellaneous knowledge that he used to think was useless, and let himself go to the next level in terms of knowledge!

"Xiaotian, thank you!" Huan Yin picked up Xiaotian again, and he was so happy that he couldn't close his mouth.

From that day on, Huan Yin's way of learning and learning changed ways. He no longer relies on a single memory, but thinks while watching. In the process of such study, he even found that the existing annotations did not match his own analysis, which means that it is very likely that the annotations in the book were wrong, and if he was still studying as before, then what he learned might have mistaken him.

In addition to knowing materials, Huan Yin repeatedly pondered the sword-casting chapter of "Infinite Sword" in sword casting, and practiced with Duan Yun every day.

Because of the study of the "Infinite Spirit Sutra", Huan Yin's understanding of the sword casting chapter of "Infinite Sword" is also different from ordinary people, and where others can't understand, he can often find the corresponding answer on the "Infinite Spirit Sutra", which makes his study of "Infinite Sword" easier.

Huan Yin didn't know what the way of forging swords on "Infinite Sword" was, because he didn't have any comparisons. However, he believed that the sword-forging methods on "Infinite Sword" were not comparable to other sword-forging methods, and he believed that what he had learned now was far more advanced than those sword-forging methods of Yijian Peak, but what he knew was far from enough.

Day after day, although Huan Yin always experienced repeated failures when he was learning to forge swords with Duan Yun, he never lost heart. Huan Yin thinks that all he can do is continue to work hard and continue to learn from the experience of failure.

Duan Yun also worked hard every day, as a mortal, he only rested for less than three hours a day, and the rest of the time he spent almost all of his time teaching Huan Yin to forge swords. His training methods were extremely strict, often allowing Huan Yin to stay by the sword stove for more than a dozen hours, and sometimes even Huan Yin couldn't sleep for several days, just to be able to forge a sword.

The efforts of the master and apprentice have obvious results, Huan Yin went from not being able to forge a sword alone at the beginning, to when he successfully cast the first fairy sword, it only took less than half a year. Although this sword is very inferior, I am afraid that even the monks in the early stage of condensation are a little disdainful, but this is also a real immortal sword.

Spring goes to autumn, and Huan Yin's days are in the sea of various classics and books, in the countless words of "Infinite Sword", and by the sword furnace on the platform of the Sword Pavilion, constantly flowing by.

This year, Huan Yin went through most of the classics in the Infinite Gate, read through the sword casting chapter of "Infinite Sword", and also cast three swords.
