Seeing that the divine thought had no effect, Zhou Nan was not discouraged. After thinking about it for a while, he started to run "Soul Determination" This time, "Soul Determination" really did not disappoint him, and it didn't take long for a strange feeling to quickly arise in his body, and he poured into a gray space with no effort along the pitch-black and restrained left hand.

The gray space is not large, and the weird feeling is just a slight turn, and everything comes to Zhou Nan's mind, as if he has seen it with his own eyes, which is very clear. Following the feeling, Zhou Nan carefully looked at the gray space.

Under the perceptive gaze of the strange sense, a series of lines of different colors soon emerged in the gray space. These lines wander and overlap, intertwining and overlapping, and interact with each other to form a strange existence. It's like having life, every time you move, you're talking. It's a pity that it's just gibberish, and there is no pattern at all.

Seeing this, the corners of Zhou Nan's mouth set off a trace of arc.

A quarter of an hour later, Zhou Nan's eyes froze. He found that these seemingly irregular lines, when he injected mana and divine thoughts into the flying sword, would recombine and turn into formations that emitted intense light. Zhilu said that he had found the answer, and following the strange feeling, Zhou Nan carefully remembered these formations in his heart.

Stop "Soul Fighting" and take back the strange feeling. Zhou Nan used the same method to stimulate the flying sword and investigate the divine thoughts, but he still couldn't see the changes in it. He understands that this is the uniqueness of "Soul Determination". As long as you practice the "Soul Determination" well, in the future, when you investigate these formations, it will be extremely smooth.

According to the memory in his mind, Zhou Nan carefully carved the formation in a jade slip. After that, he didn't stop, and inspected all the remaining low-grade magic weapons. Then the formation is engraved in the jade slip.

With more than a dozen lower-grade magic weapons, Zhou Nan got a total of three formations. There are a lot of them that are duplicates. Each low-grade magic weapon has two formations, one is a universal 'exorcism array', as long as the immortal cultivator learns the exorcism technique, then this formation can be stimulated and the magic weapon can be controlled.

Another formation, each one is different, but these magic weapons are all popular goods, and the formation is very repetitive. Zhou Nan only got the 'Wind Shadow Array' that increased the speed of the magic weapon, and the 'Golden Cutting Array' that increased the sharpness of the magic weapon.

Looking at the only three formations in the jade slip, Zhou Nan was overjoyed in his heart. Although it was only the most rudimentary formation, it was enough to make him happy for a long time. Then, he took out the silver flying sword and carefully carved three formations on the stone.

Three days later, after countless portrayals and repeated training, Zhou Nan became proficient in these three simplest formations. But he didn't stop, and continued to portray. The expression is focused and serious, and the start is steady and powerful.

But suddenly, as his last sword fell, the stone that carved the formation shattered.

Seeing this, Zhou Nan's face was overjoyed, and he sped up the speed of carving the formation.

But unfortunately, after writing down more than a dozen formations in a row, the stone still can't be broken. With a sigh, Zhou Nan stopped, calmed down, and after his mood stabilized, he savored his previous feelings.

The depiction of the formation, the stone is broken, because the stone material is ordinary, and after reaching a certain temperature, it cannot bear the powerful power of the formation, and it will be directly shattered. This also proves from the side that he has succeeded in learning. Therefore, as long as the formation depicted by Zhou Nan can continue to crumble the stone, then the formation he depicted can be regarded as entering the door.

Although he didn't know the operating principle of the Dao formation, all Zhou Nan had to do was draw a gourd according to the formation detected by the "Soul Determination". As long as you practice hard, first achieve the likeness, after achieving the god-like, the most stubborn to achieve both the form and the spirit, and repeat it thousands of times, then Zhou Nan will learn this formation.

This step, like that of a peasant painter, although without systematic knowledge. But just by comparing a painting and depicting it persistently, one day, he will become a well-known painter. The reason for this is the same.

Next, Zhou Nan fell into the portrayal of selflessness again, depicting the same formation over and over again. More than ten days passed, and gradually, the formation he carved made the stones break more often.

Once, twice, three times...

After another ten days, Zhou Nan stopped.

After more than 20 days of unremitting efforts, Zhou Nan finally raised the success rate of his depiction of the formation to the third level. But after that, no matter how hard he tried, the success rate of portraying the formation did not increase. Zhou Nanzhi said that he had reached a bottleneck, which could not be broken through in a short period of time, so he stopped and stopped drilling.

After resting for two days, Zhou Nan ate some things well, and when he was full of energy, his spirit and spirit reached his peak. He picked up the silver flying sword again. I chose the two formations of 'Exorcism Array' and 'Wind Shadow Array', and prepared to imprint them on the Cicada Wing Flying Sword.

The Cicada Wing Flying Sword is very thin, and the portrayal of the 'Wind Shadow Array' can maximize its speed advantage. The 'Exorcism Array' is the most basic formation of the magic weapon, and it cannot be abandoned. Otherwise, if other formations are imprinted, the magic weapon will be even more difficult to control if the 'exorcism array' is not depicted. It's like a wild horse that has escaped, it will definitely go berserk, and some of the gains outweigh the losses.

Holding the cicada wing flying sword in his left hand and the silver flying sword in his right hand, Zhou Nan was like a master carver, moving decisively and steadily. With each swipe of the silver flying sword, it would leave powerful scratches on the blade of the cicada wing flying sword. The silver flying sword is sharp, and the scratches are clear. It's not that hard to get to this point.

A quarter of an hour later, Zhou Nan stopped, looking at the cicada wing flying sword that had already carved the formation, his heart was full of nervousness. If the formation is successful this time, then he will truly cast his first magic weapon.

With apprehension, Zhou Nan's cicada wing flying sword was filled with mana and divine thoughts.

After a few breaths, a soft sound suddenly sounded, and Zhou Nan's tense mood instantly relaxed. After the light roar, the two formations on the cicada wing flying sword emitted a strong light, and they slowly circulated on the surface of the flying sword.

Zhou Nan took a deep breath, and with just a slight pull of his divine thoughts, the cicada wing flying sword turned into a green rainbow, and at a speed that was difficult to distinguish with the naked eye, it quickly swam in the cave, leaving behind afterimages, which were very weird and psychedelic.

After playing for a while, Zhou Nan withdrew the cicada wing flying sword and looked at it carefully.

This flying sword was something that he inadvertently made when he was in the inner city of Xuanhuo. Although it has now become a real inferior flying sword. However, it can only be regarded as a general product. After all, with the original casting materials and techniques, it was impossible to cast a low-grade flying sword.

But because of the "Soul Refinement", this mortal divine weapon has miraculously become a low-grade magic weapon. But even so, the huge flaws of the material cannot be ignored. Putting away the cicada wing flying sword, Zhou Nan lowered his head and pondered the experience of portraying the formation this time. Seriously, he didn't expect it to succeed in one go.

After a cup of tea, after going through all the experiences, Zhou Nan stood up, walked to the refined red flint stone, and channeled all the stones in turn, stimulating the vitality of the stones.

Subsequently, Zhou Nan poured all the large piles of four or five hundred catties of flint into the burning red casting furnace. By the high temperature of the magma and fire, it is smelted.

Taking advantage of this time, Zhou Nan cut out a flat boulder and carved a large flying sword mold with a silver flying sword. When he was done, he went to the casting furnace and frowned as he looked at the slowly melting flint.

This batch of purified flint stones was originally born in magma and earthfire, and after purification, it is extremely resistant to high temperatures, and it takes a lot of effort to melt these stones.

In order to speed up the melting speed, without thinking too much, Zhou Nan puffed up a large amount of mana and wrapped all the stones. His mana, which was originally a pure wood attribute, was ignited by this magma fire, as if adding fuel to the fire, and the temperature in the casting furnace rose sharply. Even the casting furnace was a little unbearable and melted.

The red flint stone melted rapidly under the intense heat. With the help of mana, in less than an hour, all the stones melted into a crystal clear red liquid. As the heat burned, the red liquid tumbled violently, and a bubble bubbled up. The sound of 'poof' is very pleasant.

I saw that the red flint had been burned into liquid. Zhou Nan wiped the sweat from his forehead, puffed up the little mana left in his body, wrapped the red liquid, and smoothly poured it into the mold that had been prepared before.

The red liquid flows rapidly along the grooves of the carved slug, and it does not take long to fill the entire mold.

Seeing that it was done, Zhou Nan breathed a sigh of relief, sat down on the spot, and recovered the mana consumed too much in his body. After half a day, after recovering his mana, he stood up and looked at the fiery red giant flying sword in the mold.

The flying swords usually used in the immortal cultivation world do not use many materials, and the weight is also very light, and the volume is also very small. But Zhou Nan's flying sword is dozens of times the volume of ordinary flying swords, which can be called weird.
