The magic circle is the slowest skill that Tang Yi has improved. In addition, he has to follow the WeChat chat group from time to time during this period, so he cannot concentrate completely. He feels that the learning efficiency is actually not particularly high.

He even sacrificed his time to go to the training hall for this. Recently, the Black Iron Training Hall is always full, and a large number of idle players will choose to go there to continue exercising the game characters. Often, if you go late, you will have no extra equipment.

On the contrary, the library was as quiet as ever. Although some people were laughing and not taking it seriously, they soon learned a lesson and received warnings from their direct departments.

Tang Yi felt that this was probably done by the people in the library who had been reading books. From the familiar chats they had with Song Lang, he could roughly judge that these people were not low in identities.

During this period, Tang Yi's training effect on strength, agility and endurance was very poor. Each item was only improved by about two points. On the contrary, the mental power improvement effect was amazing, and he directly improved by more than 7 points. Now his mental power attribute has reached 20 points.

Tang Yi had some idea of ​​the rules, perhaps the difficulty of reading the books he read directly determines the extent of spiritual improvement.

Tang Yi was nervous and had some expectations for whether the magic array could be reproduced in reality, and not only had a superficial pattern, but also had to really work.

But since the game on the other end of the computer is a real world, this should theoretically work.

The preliminary preparations were carried out simultaneously with the learning of the magic circle. When reading the basic textbooks of the magic circle, Tang Yi first directly looked through the column of the magic circle drawing materials.

If the corresponding production materials cannot be found in reality, then everything else is useless. Unless he can find a way to bring the USB flash drive to the game, it will be meaningless to master the magic array.

According to the textbooks, there are a wide variety of raw materials required for the magic circle, and you can even write a whole book separately.

Tang Yi also visited several times in the few stores in Dawn City that operate magic array materials. The main materials commonly found in the game are ordinary materials such as rainbow gold and mitril silver magic powder, and slightly more advanced ones include stardust sand and crystal liquid.

Unfortunately, these raw materials are all produced in the game world and are basically magical materials. It is impossible to find the corresponding thing in reality.

But Tang Yi did not give up easily and tried to find relevant books in the library. In addition to browsing the basic textbooks of the magic array, he also found the history book of the origin of the magic array.

However, this book is not a textbook, but only systematically introduces the origin and development of magic circles in the world of the Dark Gate. Some are similar to historical material books. This book is written in common terms, so there are very few people who borrow it.

Tang Yi found this book by chance. His current genre level is not very high, and he cannot read it without any barriers like Longyu. So he just hurriedly read this material book for a long time, and his eyes lit up in front of the computer.

There is such a short record in the origin of this magic circle: At the earliest, young and immature magicians in the Dark Gate tried hard to find various materials that could transmit magic power, but in that era of scarcity, they did not have much choice until a great sage first extracted a soft gray-black substance and became the pioneer of opening up the magic circle. This substance is called @￥#.

The last word is written in common terms, but it is not the commonly used word. Tang Yi's current genre level obviously exceeds the scope of his understanding.

Tang Yi decisively found a thick Chinese translation list from the bookshelf. After searching for a long time, he finally found this rare word. It was a direct Chinese translation called graphite powder.

When he saw this, Tang Yi in front of the computer couldn't help but take pictures. He couldn't find the corresponding things for other magic materials, but graphite powder doesn't need to be replaced at all. You can buy a bunch of them online.

Of course, on the verge of caution, Tang Yi was also worried that it would be because of translation errors. After all, the books in the library were not all right, but those possible mistakes were often caused by translation.

Tang Yi also found a list of common terms for this latest 3.0 version, and carefully compared it again. Based on the general description of this substance in the book, he basically confirmed that it was graphite powder.

In fact, in the records of the Origin Data Book, graphite powder was used as the material for making magic circles in its earliest period because this substance has a certain conductivity.

However, as time goes by, more and more people are studying magic circles, and graphite powder has also exposed more and more defects, such as conductivity, timeliness, etc., which are gradually eliminated. Later, these more adaptable magic materials appear.

Graphite powder is not the best choice, but it is the only choice in the real world. This doesn’t matter. The charging magic array is not very advanced. At least it is a try worth considering.

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

In addition to the basic drawing materials, the charging magic array also requires materials that can transmit energy, just like the boss was able to replenish the armor by extracting the energy from a crystal energy stone that day.

The problem with energy stone is not big. Through reading these few days, Tang Yi can easily find the corresponding thing in reality, diamonds.

According to the textbooks, to a certain extent, the diamonds on the earth and the energy stones in the dark gate world are actually something, both of which are a kind of elemental crystals naturally formed under high pressure and high temperature conditions.

But the difference is that the ubiquitous magic elements in the world of the Dark Gate allow this crystal to contain energy of varying sizes during its formation, allowing energy stones to be used more to provide and supplement magic energy, while the diamonds on the earth are basically used for decoration and collections.

Tang Yi was also a little worried about whether the diamonds on Earth would be ineffective due to this difference, so he had an alternative plan. He bought a full two kilograms of graphite powder specifically for this purpose. It was just a single charging magic array, which actually didn't require so much graphite powder.

An effective magic array is still very complex. It must have a magic core, an outer array diagram, a magic guide, an outer magic ring and an outer magic script. It also has strict requirements on drawing. It is not just the image you draw, but many runes even have rigorous requirements for painting order. As long as you make a mistake, the entire magic array will completely lose its original effect. In severe cases, it may even have a short circuit and explosion.
