All the preliminary materials were ready, and when the mastery of the basic magic array was improved to LV4, Tang Yi felt that the basic knowledge of drawing the magic array had been almost mastered, so he took a whole day to start trying to draw.

There are many kinds of magic arrays, such as five-pointed arrays, six-pointed arrays, seven-pointed arrays or combination arrays, etc., and the charged magic array is the most popular six-pointed array.

Tang Yi first took out a stainless steel plate and sketched the basic composition diagram of the charging magic array on it with a black oil-based pen, this process alone consumed him a morning, and he didn't even bother to eat lunch.

The skill level of LV4 is definitely not very proficient, especially when it is the first time to try, Tang Yi's drawing speed is as slow as a snail, and after the sketch is finished, he spent almost two hours to revise and improve.

Today, he still logged into the game, but this time he really just hung up in the library, spread out the magic array teaching materials in front of his eyes, and then compared each cumbersome rune one by one.

Through repeated comparison and debugging, finally at around three o'clock in the afternoon, Tang Yi's sketch was completed, and the next steps were relatively simple, he took out graphite powder and carefully smeared it on every line and rune of the sketch magic array.

Although this process is simple, it is not too fast, graphite powder as a conductive substance, connected to the energy stone and charging props, must be evenly distributed, too much or too little of a certain part, may lead to conduction failure.

This step took another two hours, and by the time the gray-black magic array had taken shape on the steel plate, the sun was already about to set.

The final step is to put in the energy transfer device and the charging power-up.

The power stone, that is, the diamond, was bought by Tang Yi in the gold store yesterday, and a diamond the size of a grain of rice used up more than 5,000 RMB for him, in fact, he could buy a bigger one, but because he was not sure whether the diamonds on the earth could really replace the power stone, so to avoid unnecessary waste, he bought a cheaper one first.

The charging prop is the inky USB flash drive.

Place the corresponding items in the corresponding position of the magic circle, the diamond is placed in the outer magic ring, and the USB flash drive is placed in the center of the magic core.

Everything is ready, and finally it is almost time to start.

In the game world, activation requires the caster's own mental power to control, a bit similar to spell release, Tang Yi's current mental power has 20 points, which is completely sufficient.

Tang Yi stretched out his hand to the position of the outer magic ring and began to chant the icicle spell softly, with the improvement of spiritual power, the success rate of this low-level spell was also higher, and soon Tang Yi felt a damp aura in his palm began to converge rapidly.

But he also knew very well that he was now unable to use any spells in reality, and sure enough, a mysterious force quickly appeared, blocking the spells that were about to take shape, but the spiritual power that had been extended could not be recovered, and the spiritual power came into contact with the outer ring of magic.

A few minutes later.

Tang Yi looked at the magic array on the steel plate with no change at all, there was no change in the slightest, reproducing the magic array or something in reality, was it really too naïve?

The first attempt ended in failure, and Tang Yi was not sure whether the reason for the failure was not feasible in itself, or whether there were some mistakes in his drawing process.

He didn't intend to give up just yet, although Tang Yi also had the mentality of failure, but in his initial preparations, there was a second backup plan.

This plan was prepared on the assumption that it would be difficult for diamonds to provide enough energy to recharge, after all, although they were the same substance, the magical elements on Earth might not reach the concentration of the Dark Gate world.

Anyway, the materials are ready, and Tang Yi intends to try one last time.

In the second plan, Tang Yi planned to use a combined magic array, and on the basis of the original charged magic array, a solar magic array would be added.

This wonderful idea still comes from the origin of the magic array, according to records, in the dark gate a long time ago, the power stone mine was far less than now, plus the difficulty of mining, resulting in the power stone was a very precious item in the past, in order to be able to recycle, some people thought of collecting energy from the sun through the magic array, replenishing the part of the energy consumed inside the energy stone.

After trial and error, this solution proved to be feasible, but the solar energy conversion was partially inefficient, and as more energy ores were discovered in the game world, more advantageous ores were mined, and the cost of the magic circle itself far exceeded the cost of mining, this ancient conversion method was completely abandoned.

The solar transformation magic array is relatively simpler, just an ordinary five-pointed array, in fact, in the world of the Dark Gate, the earlier the magic array, the simpler it is often, but correspondingly, it is also more immature, and there are certain flaws.

Tang Yi bought two stainless steel plates and two kilograms of graphite powder for this preparation, and after a hurried dinner, he also moved out the second steel plate and repeated the day's work, still sketching with an oil-based pen first, and then evenly sprinkled with graphite powder.

It was busy until the early hours of the morning, and the solar transformation array on the second steel plate was initially completed, and the calculation time was actually much less than during the day, and every time he successfully completed the entire magic array, Tang Yi could clearly feel that his proficiency was slowly improving.

However, the experiment will not be until the next day, and there will be no sunlight in the middle of the night.

When it was launched the next day, Tang Yi was not in a hurry to experiment immediately, he first launched the game and planned to check the textbook again, but when he opened the character column, he unexpectedly found that his basic magic array mastery had been improved from LV4 to LV5.

Yesterday, he was all idle in the game, and he didn't read much at all, but his skills still improved, and the reason is naturally not difficult to guess, it should be that he has been busy with the actual operation of the magic array.

This confirms his other suspicion that skill improvement is not limited to the game, and if the same method can be practiced in reality, the data will also be fed back into the game's characters.

Wait until noon, which is also the time when the summer sun is at its most intense.

Tang Yi placed the two steel plates on the floor next to the window opening, and when he opened the window, the two steel plates were next to each other, and among them, a magic lead drawn with graphite powder was connected to each other, ensuring that the entire magic circuit could be unimpeded.

The principle of this combination array is very simple, first through solar energy to the internal amount of the diamond, to replenish the magic energy that the earth diamond may not be enough, and then charge the USB flash drive.

Ready, Tang Yi began to concentrate again, extending his spiritual power, in fact, through yesterday's experiment, he had already learned how not to use spells in reality, but directly tried to release his spiritual power.
