The magic array is the slowest skill that Tang Yi has improved, and during this time, he has to pay attention to the WeChat chat group from time to time, and he can't fully concentrate, so he feels that the efficiency of learning is actually not particularly high.

He even sacrificed the time to go to the training gym for this, the Black Iron training gym is always full lately, and a large number of idle players will choose to go there to continue to train their game characters, and often go late and run out of extra equipment.

On the contrary, the library was as quiet as ever, although there were people who were giggling and not taking things seriously, but soon they learned their lesson and received a warning from their immediate department.

Tang Yi felt that this was probably done by the few people in the library who had been reading the book, and from their familiar chats with Song Lang, he could roughly judge that the identities of these people were not low.

During this time, Tang Yi's training effect on strength, agility and endurance was very poor, and each item only increased by about two points, but the improvement effect of mental power was amazing, directly increasing by more than 7 points, and now his mental power attribute has reached 20 points.

Tang Yi figured out the rules a little, maybe the difficulty of the books he reads also directly determines the degree of spiritual improvement.

Whether the magic array can be reproduced in reality, and it is not just a superficial pattern, but also a magic array that really works, Tang Yi is nervous and has a little expectation.

But since the game on the computer side is a real world, it should theoretically work.

The preparatory work in the early stage was carried out simultaneously with the study of the magic array, and when reading the basic textbook of the magic array, Tang Yi first directly found the column of the magic array drawing materials.

If he can't find the corresponding crafting materials in reality, then everything else is useless, unless he can find a way to bring the USB flash drive to the game, otherwise there is no point in mastering the magic array.

According to the textbooks, there are many kinds of raw materials needed for the magic array, and even a whole book can be written separately.

Tang Yi also visited the few stores in Dawning City that dealt in magic array materials several times, and the main raw materials common in the game were ordinary materials such as rainbow essence gold and Mithril magic powder, and slightly more advanced ones were stardust sand and crystal liquid.

Unfortunately, these ingredients are all produced in the game world, and they are basically magical materials, so it is impossible to find a corresponding in reality.

But Tang Yi did not give up easily, and worked hard to find relevant books in the library, in addition to flipping through the basic textbooks of the magic array, he also found a history book on the origin of the magic array.

However, this book is not a textbook, but only a systematic introduction to the origin and development of the magic circle in the world of the Dark Gate, somewhat similar to historical information books, this book is written in the lingua franca, so there are very few people who borrow it.

Tang Yi found this book by chance, his current lingua franca level is not very high, and he can't read without obstacles like dragon language, so he just hurriedly flipped through this information book for a long time, and his eyes lit up in front of the computer.

There is a very brief record in the origin of this magic circle: in the earliest days, the young and immature magicians in the dark gate tried to find all kinds of materials that could transmit magic power, but in that era of scarcity, they did not have much choice, until a great sage first refined a gray-black soft substance, and became the forerunner of the magic circle, this substance is called @¥#.

The last word was written in lingua franca, but it was not the kind of commonly used vocabulary, and with Tang Yi's current lingua franca level, it was obviously beyond the scope of his understanding.

Tang Yi decisively found a thick translation table of lingua franca Chinese from the shelf, and after looking for a long time, he finally found this rare word, and this is a direct translation of Chinese, called graphite powder.

When he saw this, Tang Yi in front of the computer couldn't help but take pictures, it was difficult for him to find the corresponding things for other magic materials, but graphite powder didn't need to be replaced at all, and you could buy a bunch of them online.

Of course, for the sake of prudence, Tang Yi was also worried about whether it would be due to translation errors, after all, not all the books in the library were correct, but those possible errors were often caused by translation.

For this reason, Tang Yi also found a list of common words in the latest version 3.0, carefully compared it again, and according to the general description of this substance in the book, it was basically determined that it was graphite powder.

In fact, according to the Origin Data Book, graphite powder was used as a material for the creation of magic arrays in the earliest periods because of the substance's ability to conduct conduction.

But with the passage of time, more and more people studied the magic array, and graphite powder also exposed more and more defects, such as conductivity, timeliness, etc., which were gradually completely eliminated, and then these more adaptable magic materials appeared.

Graphite powder is not the best choice, but it is the only choice in the real world, it doesn't matter, and the charged magic array is not a high-level thing, at least this is an attempt worth considering.

Tang Yi quickly placed an order on Taobao and bought 2 kilograms of graphite powder, plus two stainless steel plates, adding up to a total of only a few hundred yuan.

In addition to the basic drawing materials, the Charged Magic Array also needs to have materials that can transmit energy, just like the boss that day was able to replenish the armor by extracting the energy from a crystal power stone.

The problem with the power stone is not big, through the reading of the past few days, Tang Yi easily found the corresponding thing in reality, diamonds.

According to the textbook, to a certain extent, the diamonds on the earth and the power stones in the world of the Dark Gate are actually the same thing, and they are all elemental crystals that are naturally formed under high pressure and high temperatures.

However, the difference is that the ubiquitous magical elements in the world of the Dark Gate allow this crystal to contain energy of different sizes in the formation process, so that the power stones are more used to provide and replenish magical energy, while the earth's diamonds are basically used for decoration and collectibles.

Tang Yi was also a little worried about whether the earth's diamonds would have no effect because of this difference, so he still had an alternative plan, and the whole two kilograms of graphite powder he bought for this purpose was to explore and try, but a single charging magic array, in fact, it was far from needing so much graphite powder.

An effective magic array is still very complicated, it must have a magic core, an outer array diagram, a magic lead, an outer magic ring and an external magic text, and the requirements for drawing are also very demanding, not only the image of the painting, many runes even have strict requirements for the order of painting, as long as it is a little wrong, the entire magic array will completely lose its original effect, serious, and may even short-circuit and explode.
