"It is said that it is a classic that records all kinds of peerless learning from the Yanshi clan, it should be unusual. Putting away some thoughts in his heart, Xue Yi looked at the black book in his hand, and his eyes couldn't help but show a hint of expectation. Listening to what the old man said, this Yanshi's technique is also quite extraordinary, if he can master one or two, maybe he will have unexpected effects in the future.

Having made up his mind, Xue Yi hurriedly followed the previous method again, and caught his eye with the golden words revealed on the book.

When Xue Yi entered all the words on the first page into his mind, the black book shone slightly, and then a thin layer of black paper was gently turned, and the second page was presented in front of Xue Yi.

However, at this time, Xue Yi couldn't help but sigh at the magic of the black book, because he was already stunned by the words on the second page.

As soon as I turned to the second page, a huge golden word suddenly came into view: the table of contents of the basics, applications, and miscellaneous chapters divided this page into three major areas. As soon as I glanced at the dense text in each of these areas, an incomparably shocking feeling of dizziness rushed into my mind.

It's vast. The countless titles of each of these regions are as vast as a sea of smoke, demonstrating the breadth and profundity of this wonderful book. Xue Yi was shocked by the catalog of applications alone: blasting, energy, empty line, and machinery...... These strange techniques that Xue Yi had never heard of or seen made Xue Yi dumbfounded.

"What is this Yanshi clan studying?" At first glance, these contents look like a "Complete Record of Engineering" of ordinary people's homes, but if you look closely, you can appreciate their profundity from these words.

"This is really a treasure!" Xue Yi felt his heart beat faster. No matter what kind of knowledge it is, it is not compiled by ordinary people to be able to analyze a knowledge so thoroughly.

"Research research. Xue Yi forcibly suppressed the excitement in his heart and carefully opened the "basic chapter" of the book.

.....................

Xue Yi was completely immersed in it at this glance, and the whole person sat on the bed like a woodcut without moving, and all his mind was immersed in this Yanshi Secret Book. Reading these extremely mysterious words, Xue Yi felt that a new door was opening in front of him. This is a completely new path, a path that is completely different from the cultivation of combat power, but it is inextricably linked to it.

Xue Yi would not have known that from this moment on, he had become one of the few remaining Yanshi in this world, mastering this secret book, inheriting the 10,000-year-old foundation of this ancient and legendary race, and once again reappearing the name of Yanshi in the world.

The moonlight was cold, shining through the open window. The Yanshi Secret Archive emitted a faint golden light, which reflected the moonlight as white as silver, illuminating Xue Yi's face in a flickering light.

On the bed, Xue Yi's body that had been sitting quietly for a long time moved slightly, and he immediately opened his eyes, and the golden light under his eyes flashed.

"It's already night!" As soon as he opened his eyes and saw the sky outside, Xue Yi couldn't help but be taken aback. I didn't expect to spend a whole day researching as soon as I researched.

"It's amazing, this ...... This book is really valuable!" Xue Yi didn't bother to observe what time it was, and jumped off the bed excitedly, but he was already deeply shocked by the Yanshi Secret Text.

To put it simply, the art of Yanshi is to communicate with nature and heaven and earth, with the help of various heavenly and earthly treasures, the most simple, concise, and supreme rules are written into it, and then all kinds of sophisticated "instruments" are created to make them serve themselves.

At first glance, this has many similarities to the refiner's abilities, but there are differences between the two. The biggest difference is that the weapon needs to be artificially infused with combat power before it can be used by people, while the Yanshi technique needs to make the manufactured weapon completely autonomous, act autonomously, and provide energy independently, without the need to inject combat power into it again and again. Moreover, the latter has more types and a wide range of topics, not only in the study of weapons, but also in many other aspects. This huge book is more like an encyclopedia, and the countless magical "instruments" in it have opened Xue Yi's eyes.

At the same time, the Yanshi clan also has a unique set of cultivation methods.

It has nothing to do with the cultivation of combat power at all, and all those who practice the art of Yanshi must condense the "heart seal" in their minds. The "Heart Seal" is an extremely unique existence. It has nothing to do with combat power, but something to do with mental power. Because while starting to make each "instrument", Yanshi has to burn a small formation in its core, and it is such a formation that supports the autonomous operation of the entire instrument. The burning of each formation needs to be completed by the Yanshi at one time, that is, there must not be a trace of distraction in the middle. In this whole process, you need to consume the "heart imprint" in your mind.

Therefore, the number and quality of the heart seal also determine the strength of a Yanshi. The greater the number of heart seals, the more condensed they are, the more they can support the Yanshi to burn more complex formations, and the more powerful the "weapon" that can be made. And the cultivation of the heart seal must follow a peculiar way, formed over time.

When the number of heart seals is small, you can try to make a "device". As the number of heart seals increases, the "vessels" that can be made are more powerful and varied. All the principles of how the formation was burned and how the "device" itself operated and combined are recorded in the application section. As the old man said, the content of this part is divided into nine layers, and he can only view the content of the first layer at present, while the content of the second layer cannot be displayed, only a cold number: "one hundred". It is not difficult to guess the meaning of this "hundred", and it is very likely that it refers to the number of heart seals. When the number of condensed heart seals reaches one hundred, you can see the content of this second layer.

However, the content of this first layer alone made Xue Yi extremely excited. Because in the production method of these few "devices", Xue Yi saw two things: "magic crystal bomb" and "thruster". These two names were obviously given by Xue Yi himself, because the original name was a long list of Yanshi characters, and Xue Yi didn't bother to remember them, so he called these two images.

As the name suggests, "Magic Crystal Bomb." "It's a kind of explosive made from a simple process of Warcraft Crystals, which is much more advanced than manual detonation. The Magic Crystal Bomb with a small formation uses its own stored energy as an energy source, which can explode at any time according to the user's wishes, and can also fly short distances and change direction autonomously. And the "thruster" made Xue Yi even more excited, this small thing uses magic crystals as energy, which can be installed on utensils and can be directly installed on the human body. Once attached, it can provide a powerful impetus in any direction according to its own wishes.

At first glance, there is nothing peculiar about the role of the thruster, but don't forget, Xue Yi is good at speed! If you make more of this thruster and put it on your body, you can definitely make your speed go to the next level!

Moved by these magical "instruments", Xue Yi didn't care that the moon was already empty outside, and as soon as he put down the book, he sat up cross-legged again, trying to condense his heart seal for the first time.

This first condensation of the heart seal is not easy. Not everyone can condense into a heart seal. The Yanshi people are naturally suitable for the cultivation of the Heart Seal, of course, there is no obstacle in the condensation of the Heart Seal, but other races are different. Such a set of cultivation methods could not be suitable for the cultivation of all races, so Xue Yi had to be a little apprehensive. Although he may have the bloodline of the Yanshi clan and is also very talented in combat power cultivation, being talented in combat power cultivation does not mean that he also has an advantage in the cultivation of heart seals. However, fortunately, from the old man's mouth, Xue Yi learned that the Yanshi clan and humans were not much different in appearance, which made Xue Yi feel a little relieved.

Since they look similar, they should be able to share the same way of practice, right?

With a hint of expectation and a hint of apprehension, Xue Yi sat upright, closed his eyes, and looked solemn. Whether or not you can condense the heart seal for the first time, and how many heart seals you can condense, is also related to the level of potential in the future in the Yanshi. Therefore, Xue Yi didn't dare to be careless, and put all his body and mind into it.
