In fact, it's no wonder that Ke Yu wants to use his fist to fight this black iron block.

It's just because Ke Yu never thought that this flame spirit explosion could actually act on weapons or equipment. In his impression, Pu Fan also said that this flame spirit explosion was his self-created "refining technique".

Seeing Pu Fan laughing, Ke Yu ignored it.

He took out a hammer that was not big or small from the equipment that was included in the Xuanjie, and the hammer kept "banging".

The thumping sound seemed to know that Ke Yu was angry, and he was defending Ke Yu......

Pu Fan saw Ke Yu like this - Ke Yu was not using the fire spirit explosion, but just blindly hitting the "innocent" black iron with a hammer. The "ridicule" stopped. He realized that he had laughed a little too much, and he was afraid that it had hurt this kid's self-esteem.

"Oh, boy, are you refining weapons, look at you now, you are really hitting the iron as you said!" Pu Fan said deliberately, "Come, mobilize your fighting spirit, follow your hand, and feel the force of each hammer in your hand, whether it is big or small."

Ke Yu still didn't answer, but a layer of fighting energy was already evenly attached to the hammer.

Pu Fan saw this layer of even fighting spirit, and nodded appreciatively, he didn't expect that Ke Yu, this kid, was so smart. Knowing that with the fighting energy evenly attached to the hammer, you can more clearly feel the strength of the hammer on the black iron block, and the force fed back to the hammer.

"Very good, boy, you can use the Flame Spirit Explosion and start to remove miscellaneous!" Pu Fan praised when he saw that Ke Yu was already roughly familiar with the weight of each of his hammers.

"Old fellow, why don't you keep laughing, hmph, knowing that I have little experience, you like to make fun of me. He was chattering, but his hands were not idle.

"Flame Burst!"

I saw Ke Yu's right hand raised, his left hand shook lightly, and he pressed the black iron. Condense the fighting energy on your right hand at a point of the hammer, and at the moment when the hammer touches the black iron.

A blazing heat, an explosion of air, directly acted on the black iron. I saw that the black iron had a significant depression.

When Pu Fan saw this, he was slightly surprised, but he didn't expect that this kid really had the talent to refine weapons.

I actually knew that with skill, I condensed the Xuanhuang Qi on the tip of the hammer, and I was able to burst out with powerful power in an instant, which was used to remove impurities.

Even Pu Fan didn't expect that this Xuanhuang Qi combined with the flame spirit explosion was seamless. At the point of the eruption, the Xuanhuang Qi that was released in an instant burst out with powerful energy.

But......

"Boy, I have to say, your method is not wrong, but before you have fully mastered the technique of the Flame Spirit Explosion. You keep the fighting spirit evenly distributed in every direction of the hammer. Pu Fan is right.

Although Ke Yu didn't understand why, he still did it.

Then, the second hammer, the third hammer...... The Nth hammer went down.

The effect is not as significant as the first hammer, but it consumes more physical strength and fighting spirit.

After another hammer, Ke Yu was already exhausted, slowly sat on the ground, and lay down again.

"Why is that......"

Looking at the cloudless sky, I felt that beating the black iron in this way not only had no significant effect, but also cost double or more than double the physical strength and fighting spirit. Ke Yu asked himself suspiciously, as if he was asking Pu Fan.

"Stinky boy, don't you think I'm deliberately making things difficult for you......"

"Yes, that's right, why go the extra mile...... Instead of a faster and better method, it will be less efficient and more laborious......"

Ke Yu was still a little puzzled, staring blankly at the sky.

"Stinky boy, don't you feel that the fighting qi in your body has changed faster, and the control of the fighting qi is more proficient. ”

Hearing this, Ke Yu felt it carefully, and indeed as Pu Fan said, his dou qi transformation had indeed accelerated a lot.

"Look at this black iron block, whether the force is more even, every place is just right, and it slowly becomes smaller in all directions. ”

Ke Yu fixed his eyes and saw that this was indeed the case! It turned out that in this way of refining the weapon, the black iron block changed together in the whole body, so it gave people the illusion that the black iron block had not changed.

"It's really true, I never thought that refining weapons are so tempering people. Not only can it help me become proficient in the Flame Spirit Explosion, but it can also help me improve my fighting spirit!" Ke Yu sighed.

"At the beginning of the period, your method is a good method, if you have absolute control over the weapon you want to refine, you can completely follow your method, which has the effect of saving time and effort! But at this moment, you still need more training, laying a solid foundation, it is crucial!"

"Think about it, if you can achieve that the power released by each force point is almost the same, then you can look back and think about it, your control over the power and this flame spirit explosion, tsk......"

After listening to what Pu Fan said, Ke Yu thought thoughtfully, thought deeply, and nodded.

After resting for about half an hour, Ke Yu regained his strength and immediately began the practice of "removing miscellaneous"!

As the so-called combination of work and rest, you can get twice the result with half the effort.

Ke Yu had one hundred and two percent of his spirit at this time, and he was fully engrossed. Holding his breath and concentrating, he carefully controlled the output of the fighting qi in his body, the uniform coverage when attaching the weapon, and the uniform release of the fighting qi at the tip of the hammer.

After two more hours of tempering, the black iron in front of him had gradually changed from the size of the original palm to the size of a thumb. During this period, every time Ke Yu used the Yan Spirit Explosion, he had a new insight.

When Ke Yu hammered down again, there were two layers of gas explosions from the tip of the hammer!

"Is this an illusion?" Ke Yu couldn't believe it......

Another fire spirit explosion unleashed, and two more air explosions were released!

After cultivating for a few nights, the Flame Spirit Explosion actually mastered the second-layer Qi Explosion today.

Ke Yu was very happy, but he was still not satisfied, but was motivated and energetic. Hammer after hammer hammered the black iron......

It wasn't until this piece of black iron, which was gradually only the size of a fingernail, emitted a faint light, that he knew that this, the black iron essence!

What Ke Yu never expected was that when he mastered the two-layer air explosion, the efficiency of removing impurities was relatively increased by several times!

At the end of the day, in general. It didn't disappoint Ke Yu! The refining weapon was not like what he thought, it would delay his cultivation. On the contrary, it can promote cultivation even more!

Ke Yu didn't know that in fact, only when he was refining the weapon, would he have such an effect of promoting cultivation! Even if he did, the effect was not as obvious as Ke Yu's.

Others don't have such a set of refining techniques, ordinary people refining tools, is really hammering and beating, really relying on physical strength and endurance to remove impurities and purify materials! It is time-consuming and labor-intensive......

When Ke Yu wanted to continue refining the second piece of black iron, he suddenly realized that it was already dark......

It's getting late, and it's time for me to go back. Otherwise, Yin Shirong should be worried again......

In this way, Ke Yu carried a heavy load every day, removing fire poison for Yin Shirong, and then refining the black iron! It lasted for more than half a month.

During this time, Ke Yu has made great progress. The weight has increased from more than 40 catties to 80 catties today, and the comprehensive ability of physical fitness has been comprehensively improved.

Through this period of time, no less than a thousand times of Yan Ling Explosion! The perception of Yan Ling Explosion has also reached a higher level, reaching the fourth layer of Qi Explosion Realm! It has also made Ke Yu's purification of various refining materials faster and more efficient!

What's more, Ke Yu's one-vein space, through this period of cultivation and absorption of the fire poison energy in Yin Shirong's body, is also about to be saturated.

I think it is not far from the day when the pulse will be opened again, maybe three or five more days, or another ten days and a half months. Now if he faces that Zhao Lan again, it is estimated that he can be pressed and rubbed on the ground!

During this time, Pu Fan watched Ke Yu's strength improve by leaps and bounds, not to mention how happy he was. In such a short period of time, the strength has increased so much, according to ordinary people, it must be that the foundation is not strong, and the strength is lost.

But Pu Fan knew that this was Ke Yu's unremitting and overloaded efforts every day!

"Today, we can carry out the next two steps of cultivation in the refining weapon!" Pu Fan looked at Ke Yu with a smile and said.

Ke Yu suddenly woke up and took the first step by himself -- mastering "removing miscellaneous"! It took more than ten days to be stunned.

Deep regret came from my heart, and I suddenly felt that my efficiency was too low......

If ordinary refiners could hear Ke Yu's heart, I am afraid that they would have the heart to die. Everything is difficult at the beginning, and how many refiners have given up at the first step. How many refiners were able to complete the first step in a month, no! At least not one in the history of the Cosmos Continent! Even Pu Fan was no exception......

It also took Pu Fan a month and a half to start the second step. Of course, Ke Yu also benefited from the effect of this Flame Spirit Explosion, otherwise it would be so exaggerated and fast! If Pu Fan had just stepped into the refining weapon back then, he would have had this Flame Spirit Explosion, and it should not be much worse than Ke Yu......

"Calciner, from this step onwards, you will need to use the furnace I gave you. You also need to prepare fire, beast fire, or mortal fire!"

Pu Fan introduced.

"With your current ability, use Mortal Fire! this furnace will also increase the quality of your Mortal Fire a little bit!"

Ke Yu took out the black plain furnace, and a blazing flame was generated in the furnace, melting all the black iron essence refined during this time, and under the scorching flame, the black iron essence gradually melted.

"Oh no, you don't have a mold, and your spiritual sense and spiritual power are not open! wait for me to find out if there is a mold...... Pu Fan suddenly remembered that the refining weapon needs spiritual power to outline the model of the weapon he wants, and if he does not have spiritual power, the refiner will also have a set of molds for various weapon samples.

Spiritual power and fighting spirit are two concepts. Everyone who can cultivate will have a fighting spirit, and the stronger the fighting spirit, the stronger the person!

Fighting spirit, which can be substantiated, can be seen visually, and can be attached to substantial objects. Spiritual power, on the other hand, is a kind of creation, invisible, void and intangible.

Spiritual power is a kind of soul power that can only be generated when a practitioner breaks through to the Gathering Spirit Realm. It is often used to detect the enemy's situation, or to kill people invisibly!

But it can't cause physical damage to people, but if the two are combined and used properly, the combat effect is worlds apart. It's like two people of equal strength fighting, one uses spiritual power to attack the soul of the other, or causes vertigo, or pauses for a second, but the stronger the strength, even if it is only a momentary pause, it can determine life and death!

Therefore, spiritual power is a kind of power that overrides the fighting spirit, but also depends on the fighting spirit.

For alchemists, spirit pattern masters, and refiners, there is no doubt that spiritual power is crucial!

Spiritual power can be used for Ning Dan, Cheng Dan!

Spiritual power can be used to condense and outline weapon models!

Spiritual power is also an indispensable part of outlining spiritual patterns......

(The so-called spiritual power is more like an invisible force condensing, or squeezing, or channeling)

Now Ke Yu has nothing, how can this be good, he can only stop halfway!

But it has finally come to this point, and once it cannot be formed, it means that all these materials will be wasted, and the hard work of these days will be in vain.

How could Ke Yu let this happen! Since there is no mold, then try to create one with the Dou Qi in his body! In the Huanyu Continent, the Dou Qi will be melted by high temperatures, and no one has ever dared to use the Dou Qi to carry the objects in the furnace, whether it is during alchemy or refining weapons.

And Ke Yu wants to try!

I saw Ke Yu use the fighting energy in his body to condense into a spear shape, this mold is very similar to the mold of the dragon chanting gun!

"Ah~~" When the mold condensed into the Dou Qi (Xuanhuang Qi) touched these black iron essence melts, Ke Yu obviously felt an unprecedented heat!

"Come on, I'm not afraid of you!"

This scorching energy scorched Ke Yu's internal organs......

Ke Yu was in unbearable pain, urging the Eight Desolations with all his might, frantically using the black hole in his body to mediate and devour this scorching energy!

A few minutes passed, and the black spear made of black iron was finally formed! Ke Yu immediately blocked all the fighting energy, and this scorching energy finally slowly dissipated......

Although this is only a few minutes, for Ke Yu, it seems as long as a few reproduction eras......

Just when Ke Yu was about to die, Pu Fan said again, "Quick, Fu Ling, this mortal weapon, it seems that because of the influence of your fighting qi, that is, the influence of Xuanhuang Qi, you can actually outline the formation in it." An ordinary-level formation should be able to withstand it!"

"Formation - Blood Slaughter, Cheng!" dragged his tired body, forced out a drop of essence blood, and laid out the formation on the body of this black spear!

"It's done, it's done!" Little guy, the first mortal weapon you refined has finally succeeded!

"Blood Flame Gun!" As soon as he gave this gun its name, Ke Yu fell straight to the ground!

After all, the price and consumption he paid were too great......
