Putting down the futon, Shi An picked up the blue jade slip on the table again.

This jade slip is about the production and use of the Spirit Gathering Array. According to Yu Jian, the main function of the Spirit Gathering Array is to extremely compress the aura of the spirit stones in the outside world or in the formation, forming a spiritual mist that is directly infused into the body of the user in the array, thereby greatly shortening the cultivation time, and the degree of spiritual energy compression is directly related to the concentration of the spiritual energy in the environment or the quality of the filled spirit stones. The Spirit Gathering Array has different formations according to different cultivations, and each formation can also adjust the type of aura through the different arrangements of the array flags. As for the production of the Spirit Gathering Array, this piece of jade can only read the part of the Qi refining period. Looking closely, the various terms involved in the content of the formation are endless, and Shi An, who does not have any foundation in the formation, can't stand a word.

In addition to the big head, he found that there was also the content of a book attached to the back of the jade slip. This book is called "The Key to Formation", the author is Xin Ruyin, and the reviser is Tian Qin'er. He just briefly browsed and found that this book actually has more than 30 volumes, the content is extremely rich, but the writing is very simple and popular, starting from the understanding of the various components of the formation, to how to make the formation later, including many of the author's own cognition of the principle of formation, as well as a lot of examples of formation and in-depth thinking of the theory of formation.

In Shi An's view, this is not so much a work on formation, but rather as a record of his own learning experience in learning formations by a formation mage. After only a few glances, he was fascinated by the light-hearted and playful language and rich content, and it took him more than half an hour to read the first volume of the book.

When Shi An put down this piece of jade slip, he had a plan in his heart: now he doesn't know how to disperse, and there is no way to cultivate the "Foggy Sea Spirit Technique", so recently, he simply learned the formation knowledge in the "Formation Tips" and the first layer of the "Great Yan Decision" in the Dongtian Stone, and his divine consciousness has been nourished and strengthened in the futon. After the master came to pick him up and returned to the Four Elephant Temple, while looking for an opportunity to learn how to scatter gong, he tried to make a spirit gathering array by hand, and after everything was ready, he could step up his cultivation to the foundation building period.

No matter what the effect of the elixir is, it seems that it does not help his physique at all, so he simply put it aside. The cultivation speed will be accelerated by the use of the Spirit Gathering Array, so he can only deceive the ancestor and say that it is the Spirit Blocking Pill that has worked. The master spent many spirit stones for himself, and he would slowly find a way to earn them back. But when he thought of having to deceive Entong's recreated ancestor, Shi An couldn't help but feel sad for a while, alas, there is really no other way, or have the opportunity to use other ways to make up for all this in the future.

After calculating, Shi An began to read and digest the content of the "Formation Tips".

The book is divided into four parts, the first part of which is the first ten volumes, which mainly describes the origin of the formation, the function of the formation, the principle of operation, the basic components and the framework. The second part is the next five volumes, which mainly tell about the carving methods and main functions of various array symbols, the types of materials and production methods of array flags, and the third part is also five volumes, mainly telling a lot of formation examples, interspersed with many array people should need to create new formations through different functions, in this part of the content, the author said: A good formation mage should not only understand the depiction of the formation diagram, master the carving methods and functions of each array and the combination of formation symbols, Be familiar with the production and discharge methods of the formation flag, keep in mind the details of the formations at all levels, and more importantly, have an open mind, and be able to create new formations to meet different functional needs through different combinations of formations. The last part has more than ten volumes, and the opening chapter says that the content of the first twenty volumes is the primary formation, and these more than ten volumes are the introduction to the intermediate and advanced formations, which will generally summarize the practice content of the intermediate and advanced formations, and also list many extremely advanced formation cases.

During this time, Shi An mainly studied the principles of the primary formation in the first twenty volumes.

It may seem profound, but it's not that hard to understand.

From the perspective of structure, a complete formation is composed of several parts, such as the formation diagram, the formation symbol, the formation flag, and the spiritual source.

The formation diagram is the basis of a formation, depicting the size and basic framework structure of the array, and is the hub that connects the formation, the formation flag, the spiritual source and other parts together.

Formations are some specific symbols or words, a single formation or several formations combined together can achieve some specific functions, different formations can achieve different functions, is because the formations or combinations of formations are different, and the formation carving requires spiritual power injection.

The function of the array flag is to guide the direction and sequence of the functions of each formation, so adjusting and changing the position of the formation flag will also change the function of the formation.

Finally, the so-called spiritual source refers to spiritual stones, spiritual grasses and other items with spiritual energy, which are the power source to ensure the drive of the formation.

According to the strength of the realization function, the formation is divided into different levels such as primary, intermediate and advanced. Most of the formations of the primary formation are octahedral shapes, and the eight corners correspond to Qian, Kun, Zhen, Xun, Kan, Li, Gen, and Duibagua, or correspond to the eight gates of Hugh, death, injury, Du, Zhong, Kai, Surprise, Sheng, and Jing; the number of formation symbols used is not much, and the structure is relatively simple; the formation flag is also extremely simple, and the materials used are ordinary objects; as for the spiritual source, only the inferior ordinary or inferior attribute spirit stones can be used.

There is a significant difference between the middle and advanced formations, not only are the formations more complex, each part is composed of several elementary or intermediate formations, and the formations used are becoming more and more complex and numerous. According to what is said in the book, an ordinary intermediate formation requires two or three hundred formation talismans; the requirements of the formation flag have also increased, and the materials used in the production are becoming more and more high-end, and the difficulty in the arrangement of some advanced formations lies not in the complexity of the formation, but in the difficulty of solving the materials of the formation flag; the quality of the spiritual source has also been improved, and it is necessary to use medium-grade spirit stones, high-grade spirit stones, and even spiritual objects with more spiritual energy.

For half a month, except for going to see Zhen Qing regularly every day, the rest of the time stayed in the Cave Heaven Stone. In terms of time arrangement, he devoted a large part of his time to practicing the "Formation Tips", and the rest of the time to practice the "Great Decision".

Shi An carefully read the "Essentials of the Formation" while understanding and memorizing it attentively. The content of the first twenty volumes about the primary formation, except for a few places where he did not know the essentials due to lack of practice, the rest were already familiar with it, and if he talked about theory at this time, he was confident that he would definitely not lose to any junior formation mage in the world.

Another piece of jade is about the "Great Yan Decision", the first layer of its mental method is called the Divine Extension Technique, teaching how to exercise the five senses in the ancestral aperture, so as to strengthen the divine consciousness, the content is also very simple, he has quickly mastered it, in the dead of night every day to enter the cultivation, and at the same time with the nourishing function of the futon, his divine consciousness progress is rapid.
