Mo Han refined hundreds of catties of refined iron in the morning, but because the consumption of thunder fire was quite huge, in the afternoon, Mo Han went to the first layer of the center of the earth to cultivate, and the thunder fire suddenly absorbed a lot of fire energy, and it didn't take long to recover as before, and even better medicine was brighter than before.

In the evening, Mo Han began to learn to carve the formation diagram while practicing his mind under the guidance of the machine spirit.

The so-called array diagram is the bridge of contact between the artifact and the heaven and earth vitality and the control of the artifact, and only when an artifact has a formation diagram can it be regarded as a real artifact, and its power is more than a hundred times higher than that of ordinary weapons.

Corresponding to the division of refiners, the same formations are also divided into real weapon arrays, spiritual weapons arrays and artifact arrays, different arrays, the utility of the corresponding artifacts is different, for example, the common Gathering Yuan Array, which is to gather vitality and accelerate the cultivation of martial artists, is generally depicted on the ornaments, and the Zengyuan Array is to increase the vitality and enhance the corresponding strength of the martial artist, which is generally engraved on the weapon.

The depiction of the formation diagram is quite complex, and it is completely made by the mind, every time it is made of precision, often a small mistake will lead to the complete failure of the array, and the refiner needs to use a powerful mind to carefully depict it in order to be effective, which is also the reason why if you want to become a refiner, you must first practice the meditation.

At this time, Mo Han was half-squatting on the ground, his expression was extremely solemn, his forehead was even covered with fine beads of sweat, and there was a chaotic rune in front of his feet, those runes exuded a golden luster, looming, seemingly random, but every line was completed by Mo Han with extreme caution.

Mo Han was still engrossed, his eyes were always quietly staring at the formation diagram in front of his feet, with the slow mobilization of his mind, a golden light slowly flashed on the array, and suddenly there seemed to be someone on the ground, and the golden lines slowly appeared, constantly perfecting the formation in front of him.

However, a bead of sweat accidentally slipped from the corner of his eye into his eyes, and suddenly Mo Han squatted slightly, but after a while, the original golden line suddenly struck, and there was only a very slight deviation, and suddenly the light disappeared, and it was extremely dim in the blink of an eye.

Mo Han's face showed a burst of annoyance, and finally sighed, "It's still a failure, just such a small mistake!"

Ji Ling said: "That's natural, this depiction of the formation is not just about cultivation, even if you have extraordinary talent, you need to practice continuously to depict the formation well." ”

Mo Han nodded, if he was free in the past few days, he had been practicing the formation diagram, but until now he had never made a formation diagram, and every time it was some very slight mistakes that led to the final failure, which made him chagrined. Of course, this also made him deeply feel how difficult it was to portray the formation diagram.

Mo Han didn't say anything more, he knew that only when he had to endure hardships could he become a master. If you want to successfully portray a formation, you must work hard, and there is no other way. I saw him at the moment, and after cleaning up my mood a little, I started to portray it from scratch on the same place.

The machine spirit on the side always watched Mo Han's every move, even he had to admit that he had picked up the treasure, even if he was at the beginning, he might not be able to have the perseverance of the little guy in front of him, I don't know how many times he failed, and I don't know how many times he has started over, but he has never heard a word of complaint in his mouth.

The golden light lit up again, and suddenly a line appeared under his feet, slowly moving on the ground, gradually revealing some seemingly strange runes as time passed.

Every time the formation was depicted, the soul consciousness in Mo Han's mind was consumed hugely, but he gritted his teeth and survived.

Of course, with such a large number of depiction arrays, Mo Han's mind has also been invisibly exercised to a great extent, becoming condensed and keen, and when he is completely cultivated the next day, he can feel that his mind is constantly strengthening, and the progress compared to the previous day is undoubtedly huge.

I don't know how long it took, the lines on the ground became more and more numerous, and denser and denser, and as Mo Han continued to depict, the golden light became brighter and brighter. Suddenly, Mo Han's expression froze, and the soul consciousness in his mind emanated again, and the lines on the array map were connected to the end, and suddenly, the array emitted a strong light, and after staying for a while, the light gradually faded, and Mo Han could clearly feel that the vitality around him was uninterrupted, as if it had become condensed and majestic.

Mo Han's face was full of surprise, and he said, "Machine Spirit, it's successful." ”

Ji Ling said: "It's just lucky, but it may not be able to succeed next time." Although he didn't admit it, he was already very surprised in his heart, generally speaking, it would take at least more than a month to practice to depict the formation diagram before he had a chance to barely succeed, but Mo Han had only carved it for less than a week, and he had already successfully carved a small increase in the Yuan array.

However, as soon as the machine spirit remembered Mo Han's usual preoccupied appearance and was not moved by external objects in the slightest, his face suddenly showed a hint of relief.

In the next few days, Mo Han did not immediately start the final refining, while continuing to refine all the equipment with thunder fire, while continuing to practice the depiction of the formation diagram on the other side. Although it may not be successful every time, it is often portrayed three times, and Mo Han can succeed once, and as the number of times increases, this proportion also increases.

After a few more days, Mo Han was able to successfully depict the initial small Zengyuan Array Diagram almost every time, but the Machine Spirit passed a few more array diagrams to him, asking Mo Han to successfully depict them.

Mo Han knew that the machine spirit was for his own good, so he didn't ask too much, so he immersed himself in the depiction of the formation again, and the time taken to successfully depict the rest of the formation maps this time was greatly shortened, and he could successfully depict the second one in less than two days, followed by the third one......

By the time of the last picture, Mo Han was almost only slightly familiar, and after three successive failures, he successfully portrayed it.
