The art of forging a sword is mainly to rely on spiritual power forging to refine a sword, so the process of spiritual power forging is extremely complex and cumbersome.

This process not only needs to accurately control the change of flame temperature, but also accurately control the smelting, fusion, qualitative transformation, deformation and other complex and difficult processes of each material.

Therefore, it is quite difficult to learn, for most people, this process is not three years and five years, I am afraid it is difficult to learn, even if the mental strength is about the same as that of Aotian, it is probably impossible to do it without a year and a half.

But Aotian is not only strong enough in mental power, but also almost to the point of perversion in terms of mental power control. This is evident from the fact that he was able to control the temperature of the flame and the flow of the material from the first day.

And this may have something to do with his talent, but more often it may be that Aotian has mediocre cultivation qualifications since he was a child, but he stubbornly surpasses his own limits again and again.

Therefore, it only took Aotian less than two months to learn the method of casting spiritual power, and in yesterday's practice, he refined a semi-finished product that was extremely close to the quality of the sword.

"Aotian, your goal today is to refine a finished sword, and the quality must not be lower than that of the yellow level!" said to Aotian quite seriously after the masked woman brought Aotian to this cave again.

After this period of time together, she has learned more and more about Aotian.

She found that Aotian has a powerful potential in his body, and the more demanding you are on him, the more pressure you put on him, and the greater the amount of power and potential he will stimulate.

In her opinion, Aotian's latent willpower and energy seem to be inexhaustible and can be stimulated continuously, so every time she sets a goal for Aotian, it is impossible to accomplish it, but in the end, Aotian can almost complete the goal beyond her expectations.

"Yes!" Aotian nodded in response with a firm gaze, and his resolute face did not show the slightest embarrassment, but was full of confidence.

"Very good, let's get started!" The masked woman liked to see Aotian's confident expression, so she smiled slightly, and immediately took out a piece of purple gold ore, a piece of black jade ore, two pieces of dark iron ore, two first-level demon cores, and a bone of the black wolf of King Kong from the storage ring, and handed them to Aotian.

Aotian nodded, reached out and took the materials handed over by the masked woman, and put them into the sword-forging furnace. Then he pressed his hands on the two grooves of the sword-casting furnace, his eyes closed slightly, and his spiritual power was injected into the sword-casting furnace.

"Huh-" The furnace fire ignited, and the scorching flames turned into a ball under the drive of Aotian's spiritual power, wrapping different materials separately, and slowly melting each material.

After all the materials were melted, Aoten immediately controlled every flame in the furnace with spiritual power, reached different temperature ranges, and began to smelt each material to remove impurities.

The smelting process is very long, but Aotian has never slackened in the slightest, and has been engrossed in observing the smelting of each material.

After a long time, all the materials were smelted one after another, and Aotian began to control the fusion of each material with his mental power.

This also marks that the sword forging has entered the most important stage - spiritual power forging.

The process of casting spiritual power is extremely complex, the degree of mutual integration between each material, as well as the qualitative change of the reaction between materials, etc., all require the precise control of Aotian, and the slightest difference may affect the quality of the sword, as well as the ultimate success or failure.

So in the whole process, Aotian has almost reached a state of selflessness, all the spiritual power is concentrated in the sword casting furnace, everything around it seems to have disappeared, and the only thing left is the various liquids that are constantly tumbling.

As time passed, Aotian's brows became tighter and tighter, his complexion became tighter and tighter, and beads of sweat continued to flow down his forehead, and then slid down his angular cheeks.

On the side, the masked woman stared at the sword-forging furnace without moving, and her eyes seemed to be a little nervous and expectant.

She didn't know if Aotian would really be able to create a miracle again today and complete the goal she had explained.

The process of forging a sword is no more than blood qi cultivation, or a competition and fighting. The whole process not only consumes blood qi and Xuan qi, but also consumes a lot of spiritual power, and the recovery of spiritual power cannot be as easy as blood qi.

With Aotian's current mental power, he can only practice the complete refining process once a day at most, if he forcibly performs the second practice, the effect is definitely not good, and the mental power is excessively consumed, and the next day will also not have a good mental state, which is counterproductive.

Therefore, if the sword casting failed this time today, then Aotian can only wait until tomorrow to cast the sword for the second time.

At this moment, Aotian naturally didn't think about the ultimate success or failure, and his only thought was to spare no effort to mentally forge the materials in the sword-forging furnace. Do your best to do your best, do the best, and refine the best sword.

After a long time, the process of forging spiritual power finally entered the last stage, and it was also the last stage of sword casting-shaping.

At this stage, the swordsmith can decide on the length, width, shape, and so on of the sword according to his own design and preferences.

Although this stage mainly determines the appearance of the sword, the control of mental power is also extremely important.

If the spiritual power is controlled better, the more perfect the sword will be, and the sword body, sword grid, sword hilt and other parts will be more natural, exuding a kind of ingenious temperament.

Not only that, but in general, every swordsmith will carve the appearance of the sword in this process, carving the desired patterns and patterns on the sword body and sword grid, as well as the unique logo of their own design.

Therefore, after the sword was fully formed, Aotian carved a row of lightning symbols on the spine of the sword as its own mark.

After the shaping was completed, Aotian immediately extinguished the flames, expelled the remaining waste liquid, and then slapped the sword-casting furnace, and suddenly a cold long sword flew out, and the most slugging fell into his hand.

The long sword has a beautiful appearance, the sword body, the sword grid, and the hilt are natural, and there is a row of thunder symbols engraved on the spine of the sword, which makes people feel extraordinary from a distance.

Seeing the long sword that had just been baked in Aotian's hand, the masked woman on the side suddenly showed excitement in her eyes, and immediately quickly took the long sword from Aotian's hand and looked at it carefully.

"Yellow-grade mid-grade!" the masked woman's eyes widened suddenly, and her heart was shocked.

She never expected that Aotian would really be able to refine a yellow-level sword today, and it was also a yellow-level sword with a medium-grade quality.

"Senior, how about it, this sword should have reached the yellow level!" Aotian asked in a deep voice with a confident smile on his face.

This sword was refined by himself, so he knew best.

In the previous refining process, he thought that he had done much better than yesterday, and after the sword was formed, he could also feel that the quality of this sword was definitely far better than yesterday's semi-finished product, so he dared to conclude that the sword he refined should be able to reach the yellow level.

"Well, the yellow grade is medium-grade! It's very good, it really didn't disappoint me!" the masked woman swallowed the shock in her heart and said calmly.

But her heart was extremely excited, and she was even more amazed by Aotian's talent, Aotian was the best sword-casting talent she had ever seen, and she was also the one who could learn the art of sword-casting in the shortest time.

However, in order not to make Aotian complacent and proud, she didn't dare to show her true thoughts.

Hearing the masked woman's words, Aotian was also pleasantly surprised, although he knew that the sword he had refined could reach the yellow level, but he didn't expect that the sword he had refined would reach the middle grade of the yellow level.

"Aotian, don't be complacent because of today's small success, you have to know that refining a yellow-level sword is nothing, your future goal should be to refine an earth-level or heaven-level sword, or even create a stronger sword!"

"Well, I know my senior!" Aotian smiled and nodded solemnly.

Indeed, either don't do it, or do it to do your best, which is also the style of Aotian all the time.

Therefore, he agreed with the masked woman's words in his heart, and couldn't help but secretly make up his mind that he must become the most powerful swordsmith in the future.

"Aotian, from now on, you can be regarded as a swordsmith!" the masked woman's voice suddenly softened, "but how much you can achieve in the future can only rely on your own efforts—from tomorrow, I may not come to you again, and the future can only be on your own!"

Hearing the masked woman's words, Aotian felt a little lost in his heart, but he could also understand it.

The so-called master leads the door to practice in an individual, and he can't always rely on the guidance of the senior in front of him.

However, after getting along for a while, Aotian also has some feelings for this masked woman, and when he suddenly heard that she was leaving, he inevitably felt a little reluctant.

"Senior, how can I see you again in the future?" Aotian asked after a few moments of silence.

"If one day you become strong enough, you may see me again - by the way, you can consider temporarily joining your empire's swordsmith guild in the future, with your talent, you should be well trained, so that you can not only gain a certain social status, but also have free swordsmithing materials to support your early practice. After all, practicing the art of sword forging requires the support of a large number of materials, and it is far from enough to do it alone. Also, this sword-casting furnace will be given to you, you can put it away, and practice the sword-forging technique in the future, I hope that when we meet again, you will already be able to refine an earth-level or heaven-level sword!"

"Well, the juniors will definitely work hard!" Aotian arched his hand and said with a firm gaze.

"Alright, Aotian, put away the sword-forging furnace, and I'll send you back!"

"Yes!" Aotian nodded, and immediately came to the sword-casting furnace again, and with a thought, he put the sword-casting furnace into the storage ring.
