In the next two days, the little leopard stayed in the smelting room almost day and night.

It is still difficult to create a kunai. His current smelting iron level is not enough to complete the kunai in half a day.

The reason why it took two days was that he would try to use the Nine Dragon Divine Fire Art fire control technique during the process of creating and refining.

The Nine Dragon Divine Fire Achievement is the Wu clan-controlling magic skill, so Little Leopard will naturally not be fully learned. Whether it is the old Xingtou in the past or the Qin Xuanlong now, because he is very optimistic about the future of Little Leopard, he has passed on his martial arts technique. However, the two of them have not had a high status in the Wu family, and what they know is only the basic martial arts of the Nine Dragon Divine Fire Achievement.

However, although craftsmen like Lao Xingtou and Qin Xuanlong learned basic skills, they also knew how to use the Nine Dragon Divine Fire Art in the process of refining weapons.

In fact, the reason why the Wu family is so famous for refining weapons is that it has created a well-known brand in the martial arts world in just five hundred years, relying on the addition effect of the Nine Dragon Divine Fire Technique on refining weapons.

The Nine Dragon Divine Fire Cultivation practices the internal energy of the fire, and contains the spiritual energy of the fire between heaven and earth. The spiritual energy of the fire between heaven and earth is naturally not ordinary coal, but ordinary flames burned with charcoal are comparable. Even the best fuel in the world, the flames burned are also impure. How can I compare the fire spirit that is directly absorbed and transformed from the spiritual energy of heaven and earth?

However, it is easy to practice the internal energy of the fire action. Using the internal energy of the fire action with the refining device is an extraordinary method, and it is also a useless method.

It is said that it is amazing because the artifacts and the impurities obtained by using this method are much less than those refined by ordinary fire. Whether it is strength or toughness, they are not comparable to those refined by ordinary fire. It is said that it is useless because although this method is mysterious, people who truly practice the internal qi method of the High Deep Fire Art have no time to study it, because practicing martial arts internal qi itself requires concentration and unity, and to strive to break through its own limits and reach a higher level of cultivation. How can there be so many

Although those who practice ordinary skills have time to study the art of refining weapons, the internal energy they cultivated is not much better than ordinary flames. Even if they understand this method, their internal energy is unbearable. Only five hundred years ago, the ancestor of the Wu family, the genius of the heavenly family, not only reached the ninth level of strength, but also realized the method of using the internal energy of the Nine Dragon Divine Fire Technique to drive away impurities and improve the quality of the artifacts, which created the current Wu family in Yunzhou.

However, the complexity and difficulty of this method is no less than that of high-level martial arts, and it is not easy to understand. What Lao Xingtou and Qin Xuanlong learned is only the superficial fur. Just like the Nine Dragon Divine Fire Art taught to the little leopard, they are all basic introductory methods. Therefore, some time ago, the little leopard broke several weapons, which was also related to his attempt to use this method during the refining and governance process. Although he had experienced several failures, the cost was minimal compared to the experience he gained.

"Ding--!" A crisp hammer hit sounded, and the little leopard seemed to have exhausted his last bit of strength, and his whole body became weak. He took a breath, clamped the kunai with iron pliers, and placed him on the hot fire. Seeing the red and hot surface of the kunai, the little leopard pulled out the kunai, which was already shiny, and slowly stretched out his empty left hand to an inch away from the kunai, feeling the heat emitted by the kunai, and

At that time, he transported the inner qi of the Nine Dragon Divine Fire in his body to his left hand, and according to the weapon refining method he learned, he tried to merge with the surrounding heat. In comparison, although the heat around Kuwu is much higher than the inner qi of the half-baked Jiulong Divine Fire of the Little Leopard, it is far less pure than the inner qi of his Jiulong Divine Fire. After the inner qi of the Nine Dragon Divine Fire touches the surrounding heat flow, the heat flow trembles gently. Then, the inner qi of the Nine Dragon Divine Fire in the Little Leopard's body slowly introduced into the red hot kunwu.

"good?!"

Feeling the loss and whereabouts of the internal energy of the Nine Dragon Divine Fire in his body, the little leopard was happy. He should know that with his current skills, he could not release internal energy from the outside. Even if he used all his strength, he could only exude a hot breath on the fist he shot, making the strength and lethality of the fist more. If the internal energy is released, it is at least the level of a fourth-grade warrior. This is also the reason why he failed many times before. Although he had some experience in this method, he also made plans to fail. He did not expect that this time would be so smooth and it would be successful.

Looking at the kunwu again, as the little leopard's internal energy was introduced, the originally bright red light gradually darkened. At the same time, the endless heat in the kunwu was also transmitted to the little leopard through the inner energy of the Nine Dragon Divine Fire.

"Hiss--!" The sudden heat made the little leopard feel that his left hand was torn apart by a burnt red soldering iron, and almost shrank his hand back.

"Good guy, fortunately it's just a feeling, not real heat, otherwise my left hand would be useless!" The little leopard said in his heart, just as he was about to transfer the last trace of Lihuo inside his body into the kunai, but found that no matter how hard he tried, he could not transfer the internal energy into it.

"Is the capacity full?!" The little leopard's heart moved, and then understood, and even took back his left hand. At this time, what was flashing above Kuwu was not the bright red light, but a little dark red, with a hint of strange bright color.

Without hesitation, the little leopard inserted the built kunai directly into the cold water bucket.

"Hiss--!"

A large bunch of white mist poured out from the mouth of the barrel and spread out in the smelting room.

Standing in the white mist, a satisfied smile finally flashed across the little leopard's face.

Making iron and making weapons is a physical job and a technical job!

As the saying goes by Little Leopard in his previous life, this is a combination of strength and wisdom, not like alchemy, but only technical content.

What is the basis for making a good set of utensils?

I didn’t know about the little leopard before, but now I can answer you with confidence, four words: Thousands of tempering!

No matter what kind of weapon or magic weapon it is, these four words cannot be separated from. If you reduce these four words, you will be the word "hardening".

The so-called hammer is the big hammer in the little leopard's hand. The meaning of hammering is to refine fire, put the objects in the stove for burning. The combination of the two forms the basis of the way of refining weapons.

It is like a big tree, and the word "hardening" is the main trunk that constitutes the entire way of refining weapons.

As for shaping, opening the edge, blood sacrifice, spiritual communication, prohibition, and other countless methods of refining weapons are just their branches and leaves.

As the main trunk of refining weapons, the method is also emphasized.

Hammer does not mean that you hold a big hammer and hammer it randomly against a piece of material. The result of that is to hammer a good piece of material into waste. Of course, if you are born with great luck and hammer it all in a mess, you may be able to hammer it into a magic weapon. However, this kind of luck is generally only the legendary ancestor Hongjun, so ordinary people should forget it.
