For the next two days, the little leopard stayed in the smelting room almost all night.

To build kunai, it is not difficult for the little leopard, his current level of smelting and ironing, two kunai, it doesn't take two days at all, and most of the days can be completed.

The reason why it took two full days was because he would try to use the fire control technique of the Nine Dragons Divine Fire Gong in the process of building and refining.

The Nine Dragons Divine Fire Gong is the Wu clan's Zhen Clan's Divine Skill, and the little leopard's learning will naturally not be complete, whether it is the old Xing Tou in the past, or the current Qin Xuanlong, because he is extremely optimistic about the future of the little leopard, he has passed on this technique, but the status of the two in the Wu family is not high, and what they know is only the basic practice of the Nine Dragons Divine Fire Skill.

However, although craftsmen like Lao Xing Tou and Qin Xuanlong have learned basic exercises, they also know how to use the Nine Dragons Divine Fire Skill in the process of refining weapons.

In fact, the reason why the Wu family is so famous in refining weapons is that it only took five hundred years to create a well-known brand in the martial arts, relying on the bonus effect of this Nine Dragons Divine Fire Skill on refining weapons.

The Nine Dragons Divine Fire Gong cultivates the internal qi of the fire line, and it contains the aura of the fire between heaven and earth, and the fire spirit of the heaven and the earth, which is naturally not an ordinary coal and an ordinary flame burned with charcoal, even if it is the best fuel in the world, the flame that burns out is also mixed and impure, where can it be compared to the fire aura that is directly absorbed and transformed from the aura of heaven and earth?

It's just that it's easy to cultivate the internal qi of the fire line, but this method of using one's own fire line internal qi to cooperate with the refining weapon is a great method, and it is also a method of chicken ribs.

It is said that it is amazing because the utensils obtained by using this method of refining tools are much less impurities than those refined by fire, and neither the strength nor the tenacity of the utensils refined by ordinary fire are comparable. It is said that it is chicken ribs, because although this method is mysterious, but the person who really cultivates the advanced fire line internal qi method does not have time to study him, because the cultivation of martial arts internal qi itself needs to concentrate on the same, and strive to break through its own limits and reach a higher cultivation realm, where will there be so much time to delve into the knowledge of refining weapons, and those who practice ordinary exercises, although they have time to study the way of refining weapons, but the internal qi they cultivate is mixed and impure, and it is not much better than ordinary flames, even if they understand this method, their own internal qi is unbearable to use, only five hundred years ago, the ancestor of the Wu family, the genius of the heavens, not only did the strength reach the nine grades, but also realized the method of using the internal qi of the Nine Dragons Divine Fire Gong to drive away impurities and improve the quality of the utensils, which created the current Yunzhou Wu family.

It's just that this method is no less complex and difficult than high-level martial arts, and it is not easy to understand, what Lao Xing Tou and Qin Xuanlong have learned is only the skin, just like the Nine Dragons Divine Fire Skill taught to the little leopard, it is the basic entry method, so, some time ago, the little leopard refined several blades, and it is also related to his attempt to use this method in the process of refining, although he has experienced several failures, compared to the experience he has gained, the price is simply minimal.

"Ding-!" A crisp hammer sounded, the little leopard seemed to have been drained of the last trace of strength, the whole person also became sluggish, took a breath, clamped the kunai that had just been built with iron tongs, and put him on the hot fire, seeing the red hot appearance of the kunai's surface, the little leopard pulled out the kunai that was already red and shiny, and slowly stretched out his empty left hand an inch away from the kunai, feeling the heat emitted by the kunai, and at the same time transporting the Nine Dragons Divine Fire internal qi in his body to his left hand, according to the refining method he learned, trying to fuse with the surrounding heat, in comparisonAlthough the heat around Kunai is much higher than the little leopard's current half-hung Nine Dragons Divine Fire internal qi, it is far less pure than his Nine Dragons Divine Fire internal qi, after the Nine Dragons Divine Fire internal qi touches the surrounding heat flow, the heat flow trembles slightly, and then, the Nine Dragons Divine Fire internal qi in the little leopard's body is slowly introduced into the red-hot Kunai.

"Okay?!"

Feeling the loss and whereabouts of the Nine Dragons Divine Fire internal qi in his body, the little leopard was overjoyed, knowing that with his current skills, he could not achieve the release of internal qi no matter what, even if he used all his strength, he could only exude a scorching breath on the fist he played, so that the strength and lethality of the fist were greater, and the internal qi was released, which was at least to reach the realm of the four-grade martial artist to be able to do it, which was also the reason why he had repeatedly failed before, although he had some experience in this method, but he was also ready to fail, I didn't expect it to go so smoothly this time.

Looking at the kunai again, with the introduction of the little leopard's internal qi, the original red light gradually dimmed, and at the same time, the boundless heat in the kunai was also transmitted to the little leopard through the Nine Dragons Divine Fire internal qi.

"Shhh

"Good fellow, fortunately, it's just feeling, not real heat, otherwise, my left hand would be useless!" The little leopard said secretly in his heart, and was about to cross the last trace of fire internal qi in his body into the suffering, but found that no matter how hard he tried, he couldn't cross the internal qi into it.

"Is the capacity full?!" The little leopard's heart moved, and he immediately understood, and even took his left hand back, at this time, the light that flashed on the kunai was no longer a red light, but a little dark red, with a hint of demonic brightness.

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

"Sizzle!"

A large white mist poured out of the mouth of the barrel and spread through the smelting room.

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

Hammering iron refining is not only a physical work, but also a technical work!

To paraphrase the saying of the little leopard in his previous life, this is a combination of strength and wisdom, not like alchemy, only technical content.

What is the basis for making a good pair?

In the past, the little leopard didn't know, but now the little leopard can answer you with great confidence, four words: tempered!

No matter what kind of weapon magic weapon, it is inseparable from these four words, and if these four words are reduced again, it is the word "tempering".

The so-called hammer is the big hammer in the hands of the little leopard, the meaning of hammering, the so-called refining, is refining fire, putting the utensils in the furnace to burn, the combination of the two, it forms the basis of the way of refining.

Just like a big tree, the word "tempering" is the backbone of the entire refining path.

As for shaping, opening, blood sacrifice, channeling, prohibition, and countless other refining methods, they are just their branches and leaves.

And the hammering and refining, which are the backbone of the way of refining, are also method-oriented.

Hammer, not for you to hold a sledgehammer, against a piece of material hammer, the result of that is to hammer a good piece of material into waste, of course, if you are born lucky, a mess hammer down, I can't really hammer you into a magic weapon, however, this kind of luck is generally the legendary Hongjun ancestor only, ordinary people, or forget it.
