This is a simple formation he figured out last night, using a stone slab as a formation diagram, with a drainage array and a spiritual source groove on it, and a flow receiving array on the rune knife, so that the aura of the spirit stone in the formation will be continuously sent into the rune knife, and he can easily complete the carving and modification of the formation rune, because this formation is extremely simple, so even the array flag is not needed.

The two formations of drainage and receiving flow are the most commonly used in low-level formations, if you directly find someone to carve on the stone slab and the talisman knife respectively, the shopkeeper must be able to easily see Shi An's intentions. If you let the guy do something in the middle of the portrayal process, your plan will inevitably be aborted. Therefore, Shi An added a dragon formation that could connect several low-level formations together in the drainage formation.

The Dragon Formation Talisman is the basic formation talisman in the intermediate formation, which Shi An found in the last ten volumes of "Formation Tips", and the two sword formation mages in those shops are absolutely unrecognizable. The formation composed of two rune arrays of drainage and closure and a spiritual source slot is divided into nine parts in the name of testing, which can not only ensure the operation of the formation, but also will not be recognized by people, and it will definitely not be known.

The most ridiculous thing is that the shopkeeper Yu, although he expected that his own test was just a disguise, and he could guess that the purpose of this move was to let the last guy make a formation talisman on the talisman for himself, but he definitely couldn't guess that the real highlight was the previous test. However, in order to prevent accidents, Shi An also had to endure the pain of producing a spirit stone as a reward for carving the flow array talisman.

In the afternoon, the guy came to Shi An with a carved talisman knife. At noon, he and Yu studied with the shopkeeper for a long time, and although he recognized that it was a flow array talisman, he still couldn't figure out what Shi An's purpose was. So after getting a spirit stone, he went back happily.

As soon as Shi An waited for him to leave, he couldn't wait to enter the Cave Heaven Stone for testing, and sure enough, as he expected, with the rune knife as the carving tool and the rune plate as the base, a low-grade spirit stone was placed on it, and the required array talisman could be carved on other stone slabs, of course, the carved stone slab must be placed on top of the rune plate. It seems that this operation was very successful and successful, not only because he obtained a set of tools for making formation talismans, but more importantly, it proved that he was able to flexibly apply the principles and rules of the formation he had learned.

This set of tools was called the "Yi Fu Knife" and "Yi Fu Plate" by later generations, or collectively referred to as the "Yi Fu Tool", and became an entry tool for formation practitioners in the formation world who had not yet reached the middle stage of Qi refining, which is not to be mentioned later.

At night, Shi An was secretly proud, and at the same time, he kept thinking about how to use this set of tools in his hand to earn spirit stones in the future. Because this rune knife can only be used on the stone slab above the rune board, this means that this set of tools cannot be used anywhere at will, and if you follow the current formation process, this set of tools is really useless.

The current general process of arranging the formation is: the formation mage or the formation shop designs the formation map, the formation symbol, and the position of the formation flag and spirit stone according to the requirements of the formation, and then goes to the site to measure the site, and then outlines the formation map, carves the formation symbol, places the formation flag and spirit stone, and then debugs the formation, corrects the formation, and finally can be delivered. In the whole process, the inscription is the most complex and takes the longest time. Formation mages or formation shops often have to be completed by one person or a very small number of people out of the requirements of confidentiality and their own technical confidentiality, so it takes several days to set up a formation.

The success of the production of rune knives and rune plates gave Shi An a new understanding of the formation:

First of all, as long as the design is reasonable, different people can complete different parts of the formation and merge them together to be equally effective.

Secondly, there is no essential difference between the formation diagram, the formation symbol and other formation components, which are engraved on the ground and engraved on the stone slab.

Third, the size of the formation has nothing to do with whether it can produce utility, and no matter how small the formation is, it can also drive the formation. Generally, the formation mage believes that the size of all the formation symbols in a formation should be the same, and the size of each formation symbol should match the size of the formation map, for example, a formation covering an area of three zhang, the size of all its formation symbols should be about one foot, and a formation covering an area of thirty zhang, all the formation symbols are about the size of one zhang. From today's test, it can be seen that the size of the drainage array on the rune board inside the Yizhi rune is several times that of the flow array on the rune knife, but the final effect is exactly the same.

Through the above three points, a bold new idea of arranging the formation gradually formed in Shi An's mind: the pre-designed formation is divided into several parts according to the different components, and after being completed by different people, it is directly spliced at the layout site, and the main work of the formation shop is not to carve the formation on the spot, but to "produce" a large number of formation components in advance, and the efficiency is naturally greatly improved.

As for the production of components, it is also very simple: the formation diagram composed of simple lines is directly formed, and the guys are engraved on the stone bars one by one in advance, and the number of stone bars can be decided according to the size of the array when used. The Lingyuan Groove and the Array Flag Groove have no technical content, and they can also allow the guys to carve the stone slab according to the specifications of the groove.

Arrays are a bit more cumbersome. The general formation talisman in the formation and the formation of Fang Cun Pavilion have mastered the correct carving method, such as the drainage array talisman, the flow array talisman, the trigger array talisman, the alert array talisman, the siege array talisman, etc., which do not involve any technical secrets, and also let the guys engrave it on a one-foot-square stone slab in advance;

Then there is only one problem in front of Shi An now, that is, how to let the core formation talisman he master still not be mastered by others after the formation is arranged, this is the only way for him to accumulate spirit stones.

After a few days of repeated attempts, Shi An successfully developed a new array talisman, which is composed of the original blinding array talisman, fluorescent array talisman, mist array and spirit storage array, the main function is to make the stone slab engraved with this array be covered with a layer of light and shadow that cannot be removed, so that people can not see the pattern of the array talisman, in which the role of the spirit storage array is very important, it is necessary to absorb and store the aura in the magic circle for this array to use, to ensure that it is still effective for a long time in the situation that there is no spirit stone drive in the magic circle, Shi An named it " Square Inch Array".

Such a new set of layout workflow has taken shape, but it still takes a lot of effort for Shi An to put it into use, mainly because the shopkeeper does not want to make any changes to the work process.

However, he still couldn't withstand Shi An's repeated requests, and finally agreed to try it in the shop for a month. And once he tried it, the shopkeeper was no longer willing to adjust the process back.

The original number of personnel in the store remains the same, and the daily work of four of them is to carve the formation talisman on the stone slab, and each person only repeats the engraving of three or five general array talismans, and the daily work of the fifth guy is to carve the lines of the formation diagram and the spiritual source groove and the array flag groove on the stone bar. Shi An's main job is to carve the formation runes, but he only carves the key formation runes and square inch formation runes required according to the requirements of the formation work he receives. The job of the sixth guy is to go to the scene of the formation, and according to the pre-designed formation, the carved stone strips and stone slabs are fixed and placed.

Now as far as Fang Cun Pavilion is concerned, as long as the daily work of carving the stone slab can be carried out normally, it is a matter of time to get the on-site arrangement.

Shi An's correction of a large number of formation symbols has made the formation effect good; some low-level formations that are not available in Kaiyuan City have been introduced, and new formations with more functions have appeared; and the new formation process has made the formation more efficient. The combination of the three, Fang Cun Pavilion's business has really changed a lot.

Thousands of years later, this formation model, which is named "Yizhi Formation Method", has become the mainstream formation mode of the entire human world, and Shi An is naturally regarded as the originator of this genre.
