The key to drawing the spiritual map, first, is that this spiritual power should be evenly output, and it cannot be strong or weak. The second is that when painting intersections, it is necessary to increase the strength of spiritual power output. This requires precise control of spiritual power.

Ling Li's level, the average student needs to take nearly two days to complete the formation pattern copying homework, he can easily do it in ten minutes, so there is not a lot of work to spare.

In fact, it is very difficult to copy and depict a complete spiritual formation pattern on this spirit board, and there are no pauses and breaks in the middle, it must be done in one go, and it must be extremely accurate. As for the two simplest basic formation diagrams on the blackboard, if you want to depict each one completely, you can't complete it without twenty or thirty times of practice.

This is actually because Ling Li's current spiritual power is too strong, so he feels that this kind of operation is very simple.

He returned to the dormitory after brushing books in the library for an hour, but saw that Li Weijia was in the dormitory, practicing copying and engraving on a spirit board, and had just learned the basic formation pattern in the morning.

In fact, the students who can be admitted to the Western Qin Military Academy have good study habits and work hard.

To draw a pattern diagram, we must first concentrate and be distracted.

Ling Li stood behind Li Wei's family and watched him practice copying the formation pattern.

I saw him put a spirit plate made of green thorn jujube wood in front of him, pinched a spirit trick with his right hand, and his eyes were firmly fixed on the spirit board in front of him. After a while, with a fluctuation of spiritual power, a condensed mental power leaked out of his sea of consciousness and projected onto the spirit board in front of him.

That spiritual power was like a laser pointer, under his control, he drove the surrounding wood attribute source power to carve a line on the spirit board, and as the spirit power beam slowly moved, a figure gradually appeared on the spirit board.

This pattern is the "need" pattern pattern that Zhou Ping just talked about in the morning.

This "need" array is formed by the intersection of a total of sixteen spiritual lines, each of which must be completed in one go, with no pauses or breaks in between. Ling Li could feel that when Li Weijia was drawing the spirit map, whenever he encountered the intersection of the spirit line and the spirit line, there would be a slight fluctuation in the spiritual power, and later, this fluctuation became bigger and bigger.

When Li Weijia was carving the thirteenth spiritual line, there was a sudden "snap" sound, and sparks flashed on the spirit board, and a faint wisp of green smoke came out, and a small hole the size of a needle tip was pierced at an intersection of the formation pattern map that had been drawn.

"Alas, failed!" Li Weijia sighed and threw the scrapped spirit board on the desk.

"What's the difference when the Spiritual Thread crosses the intersection?" Ling Li picked up the scrapped spirit board, looked at it carefully, and then squinted his eyes and asked the little fat man.

"Hmm, those carved spirit lines will produce a kind of repulsive force, so when passing through the intersection, you need to double the spirit power to fuse the two spirit lines and depict the source pattern array, the most laborious thing is this kind of place, if you are not careful, the entire spirit plate will be scrapped." Li Weijia spread out his hands and made a helpless gesture.

Ling Li's spiritual power was much stronger than that of the Li Wei family, and after observing it, he already understood his weaknesses.

Li Weijia should not have practiced spiritual power-related exercises. There is no way, the mental strength is not strong enough, and it is difficult to pass through the intersection when painting.

Ling Li had obtained several spiritual power cultivation techniques from the Secret Realm Trial Inheritance Tower, among which there was a "Stargazing Technique" that was more suitable for most of the martial artists on the Chiyan Continent to cultivate spiritual power. But he can't just take out this kind of precious exercise to give it away, this kid is not his son or apprentice, and everyone's friendship is not to the level where they can share some resources. Besides, even if the Li Wei family wants to worship him as a teacher, they are not qualified enough.

Returning to his seat, Ling Li continued to read the book.

This time it was a book of "Elementary Metal Materials", and after weighing it repeatedly, the minor courses he finally chose were actually utensils manufacturing and pharmaceuticals. He took the path of refining the body flow, in order to hide his strength, he usually tried his best to suppress his qi and blood and source force cultivation, and the training method of the Battle Academy and the Mecha Academy, which mainly focused on qi and blood and source force cultivation, was not suitable for him.

It seems that it is difficult to take off the auxiliary label on his body.

In the past few days, he has been brushing up on the making of utensils, starting with basic materials.

The artifact materials are divided into two categories: mortal products and source force spirit materials, and the spirit materials are divided into four types: "heaven, earth, xuan, and yellow". Xuan-level spiritual materials belong to intermediate-level artifact materials, and even the seniors in the upper grades can only see more than a hundred kinds, as for the earth-level and heaven-level spiritual materials, they are rare treasures that belong to the Heavenly Essence and Earth, and they are not at all accessible to people of their level.

There are two types of tools: industrialized manufacturing and handmade, and the so-called "spiritual weapons" engraved with the source pattern can only be completed by hand.

The process of hand-making is mainly divided into five steps: first, the selection and grinding of manufacturing materials, second, the smelting of spiritual materials, that is, the grinding into powdery materials are added to the furnace in a certain proportion and order to melt into a liquid state, third, the billet is cast, that is, the molten liquid is cast into the pre-made mold, and so on after cooling, it is made into a blank, and fourth, the source pattern is depicted, which requires the crafter to use spiritual power to carve out the formation inside the blank, so that the manufactured utensils have special properties, so as to become the so-called spiritual weapon. However, there is no depiction of the upper battle diagram on the utensils of the mortal products, and there are no special additional attributes. Fifth, forging and refining, that is, the prefabricated blank is repeatedly hammered after heating, removing impurities, and removing turnips. Finally, it is also necessary to use files, grinding wheels, abrasive cloths and other shapes to modify and add decoration to make it beautiful.

Each of these steps requires careful care and a great deal of practical experience.

For example, during smelting, the proportion of raw materials will change randomly due to different qualities, and the proportion of materials added to the maker also needs to be adjusted randomly, and it cannot be added rigidly and dogmatically according to the quantity above the refining recipe. When smelting, every slight change will lead to a change in the subsequent process, which requires a lot of practical experience to achieve accurate control.

In fact, the most important step in hand-making is the depiction of the formation diagram, the same quality of the blank, in the hands of different manufacturers, due to the difference in the number and fineness of the carved formation diagram, will lead to a huge difference in the power of additional attributes.

If you want to depict the source pattern pattern on the artifact, you need to have a strong spiritual power as a support.

However, the power of spiritual mind is a special talent, and only two or three people in a hundred people have this powerful ability, and not everyone can have it, which can be described as one in a hundred. And the level of the strength of the spiritual mind is the grade mark of the crafter or apothecary. Generally speaking, both making utensils and making medicine require strong spiritual power, and the maker also studies medicine, while some pharmacists also learn to make medicine at the same time, and the two are the same, the difference is only which one is the main one.

Ling Li, on the other hand, did not have this kind of choice trouble, because he majored in source pattern science, which was somewhat similar to the chip designer on the Blue Star, whether it was medicine or instrument making, it was a minor course for him.
