Things developed as Lu Yang had expected. In the end, Zhao Xuhe sold "Nine Changes Dragon Technique" to him at a low price of 1500 contribution points. People are like this when they are in debt. After receiving the "Nine Transformation Dragon Mantra", Lu Yang immediately returned to the cave abode and firmly memorized the content of the cultivation method word by word, before putting it away again. "Unfortunately, I can't cultivate now..." After turning into a bloody shadow, his cultivation level did not increase or decrease, and he would always stay in the late stage of Qi Refining. Even if he wanted to dissipate his strength, he could only wait for the next life. Having said this, Lu Yang was not in a hurry to commit suicide. After all, time is precious, and even if he has the Book of the Hundred Realms, he will not easily waste it. Even if he cannot cultivate, there are other places where he can continue to improve. Thinking of this, Lu Yang took out Fairy Qingchen's "Secret Explanation to Array Treasures" from his storage bag. That's right, he wants to learn array formations! There are four arts of cultivation, formations, weapons, and talismans. Anyone with one skill will immediately become a high-level talent in the cultivation world and will be popular anywhere. For example, Fairy Qingchen. Lu Yang felt that this person was actually a talent who not only knew array formations, but also could refine array formations into magical equipment. Unfortunately, he had a bad eye for men, and he had fallen for scumbags who turned against others. Therefore, in both lives, he died in hatred. Opening "Secret Explanation of Array Treasures", Lu Yang couldn't help but sigh on the first page of the opening page. [The so-called array treasure means using the array as a treasure and using the treasure as an array. The two complement each other. Among them, the skills are developed by me through my painstaking efforts...] [If you want to learn this path, you must have talent and hard work.] After the opening preface, the second page is filled with dense lines, and each line has a note explaining what the line means. [The way of array formation is mainly based on array patterns. We can draw the array patterns and depict heaven and earth. Only then can we borrow the wonders of heaven and earth. However, the number of heaven and earth exhausted the mysteries of the world and it is difficult to comprehend, let alone transform them into array patterns. It requires extraordinary understanding. Only by mastering the array patterns well can we be able to learn arrays.] [Very good, now you have a certain understanding of the basic principles of array formations.] [Next, turn to page three. Let's take a look at the following simple example and apply the knowledge we have just learned into practice.] On the third page, an extremely complex and cumbersome pattern came into Lu Yang's eyes. This is the formation diagram? Lu Yang touched his chin. The so-called unlocking the array diagram was actually to distinguish the composition of the array patterns in the array and deduce the function of the array. Array patterns are the foundation of all array formations. Whether an array can take effect mainly depends on whether the combination of array patterns is reasonable, whether there are conflicts, and whether it can form a complete link and operate. "Interesting." Lu Yang smiled confidently and felt that this did not seem particularly difficult: "With my talent and hard work, I am determined to get a simple array diagram!" A month later. Lu Yang sat blankly on the futon, with a large number of manuscripts piled up next to him, all of which contained the results of his calculations. He was extremely decadent. In his hand were combinations of array patterns. After an unknown period of time, Lu Yang's fingertips suddenly lit up with a ray of light. "Done!?" Lu Yang instantly stood up, his face filled with joy. He carefully looked at the array patterns he had pieced together, counted silently for a moment, and then revealed a puzzled look: "That's not right, how did it work?" "How does this thing work?" It was obviously the result of a month of hard work, but in the end, he couldn't understand why it could be used. This feeling simply drove Lu Yang crazy. After a month of hard training, he now had a deeper understanding of formations. In short, arrays and programming are very similar. The so-called understanding of the formation path is to grab the usable parts from the mountain of shit written by heaven and earth, and compose your own code. However, if you don't know how to do array formations, you just don't know how to do it. It's like looking for gold in a mountain of shit. People without talent will only be like Lu Yang now. Instead of digging out any gold, they will find out a pile of shit instead. "No matter what, I still found something." Lu Yang sighed and continued to study without sleep and food. It took more than a month before he finally solved the pattern in his hand. "This is an illumination array!" "The area covered by the array is full of light, and most methods of concealment will fail. Other than that, there is no attack or defense..." Lu Yang looked haggard and his eyes were bloodshot, but his face was filled with excitement. With a full sense of accomplishment, he opened the third page of "Secret Explanation of Array Treasures". [In fact, it's normal that you can't undo it.] [The title on the third page is mainly to let you understand how difficult formations are. Understand formations with a humble heart and don't always aim too high.] Lu Yang: "..." "What an animal! Beast!" Lu Yang suddenly stood up and threw the book in his hand to the ground. He was now 100% sure that this was definitely the array book written by the Sage Sect Array Master! After a while, Lu Yang picked up the book again. There is no way. There are some things that don't care whether you like it or not, whether you understand it, or whether you want to do it. For the sake of life, you still have to grit your teeth and continue to do it. However, after further study, Lu Yang found that his talent was not as bad as he imagined. As the book says, the cumbersome pattern on the third page is not for beginners at all, so Lu Yang was stuck on it for two months. However, there are benefits. Now that he has changed to some easy-to-understand formations, Lu Yang's learning speed has become much faster visibly. Occasionally, he will encounter stuck places, and it will take a few days to study it. It also allows Lu Yang, who had been severely beaten before, to regain his confidence. I don't know the age in the cave, but time flies by. In the blink of an eye, twenty years had passed. During this period, Lu Yang could be said to have ignored what was happening outside the window. He could only read only array books. He could not even be bothered to pay the rent of the cave abode and lived directly in the outer gate. After all, he couldn't cultivate now and no longer had hard needs, so he naturally stopped working. In the past twenty years, almost every few years, a chosen son with great fortune like Xiao Shiye in the past would suddenly rise from the outer sect. However, when the chosen one obtains a great opportunity that everyone in the Sage Sect knows, he will suddenly disappear again. Along with them, there were a large number of unlucky people who had evil intentions and wanted to hug their thighs and take advantage of their luck after discovering the fate of the chosen one. "This is the senior fishing again..." Every time he heard similar news, Lu Yang was panicked. After all, with Xiao Shi and Ye Zhuyu around, he would only stay away from the chosen one. He couldn't afford to offend him, so he could only hide. There was also Zhao Xuhe. Twenty years later, he had reached the peak of Qi Refining and became a famous true disciple of the Sage Sect. However, he failed to break through to the Foundation Establishment realm a few years ago and passed away. In this regard, Lu Yang only sighed and no longer cared. What really made Lu Yang happy was that after twenty years of hard study, he had finally thoroughly studied the knowledge of "Secret Explanation of Array Treasures". In the cave abode, Lu Yang's entire mind was focused on the sword pellet in front of him. At this moment, he was unable to even maintain his human form, and his bloody shadow was extremely dim. This is a sign that the end is approaching. The side effects of cultivating the Demonic Blood Light in the past finally came to the door, causing him to run out of life when he was only forty years old and his oil was exhausted. However, Lu Yang didn't care about this and was still focused on carving the array formation. Even when he was about to die, he still did not get up, let alone try to take any remedial actions, because that would only interrupt his inspiration, and he did not want to waste precious inspiration. "I understand! Wait... No, it's wrong..." "Oh right! Right... No, hey, it's still not right... Oh, right, right!" After a long time, finally, just as Lu Yang's bloody shadow almost dissipated and the moment when life and death were at the junction, Lu Yang suddenly opened his eyes wide-- "Hahaha! I succeeded!" Seeing the formation patterns he had carefully traced splicing together around the sword pill and finally running successfully, Lu Yang suddenly burst out laughing, and his laughter echoed in the cave abode. He lost his breath in laughter. "Hundred Books!"
