After leaving Lijia Auction House, Qin Long returned to Shiyu's hut in the outer city, took out all the wolf bones from the space storage bag, and stacked them in the courtyard.

Three thousand demon wolf spines instantly covered the entire small courtyard, and the white bones were so dense and cold.

After arranging the wolf bones, Qin Long first made some simple calculations.

He told Shuang Yue that he needed fifteen spines to refine a weapon, but that was not the case. When refining a second-level weapon, Qin Long only needed less than fifteen demon wolf spines.

In other words, Qin Long can get a small amount of spine rebate for every weapon he refines.

Putting aside the 20% gold coins he would receive from Shuangyue in the future, Qin Long melted all three thousand wolf bones into weapons and still had more than a hundred left. This was a huge kickback.

"laugh…"

A large amount of essence flew out from Qin Long's palm as the Yin-Yang fish, covering the ground around him. As the Yin-Yang fish rotated, the spines of the demon wolf on the ground began to melt and condensed into bone-white beads.

Qin Long took out more than a hundred bone beads from the pile, then held them up with both hands, took the remaining bone beads back into the house, threw them all into the great alchemy furnace, and then poured in the essence in his body as if it were free of charge.

It wasn't until the alchemy furnace was getting full that the yin and yang fish were put into it and stirred.

"If Shuangyue sees me refining weapons like this, will she change her previous idea of ​​only collecting some weapons every day?" Qin Long said while looking at the Great Alchemy Furnace.

When practicing the bone blade in front of Shuangyue, Qin Long did use his full strength. Although the internal strength was very fast, it was far from the level of being able to wave into an army.

But that was then, and this is now. Using an alchemy furnace to smelt materials was Qin Longxin's idea, and the source of his inspiration was casting molds.

Weapon refiners in the world of cultivation often use spiritual energy to forge the weapon into shape after smelting. Although the quality of the weapon can be guaranteed in this way, it is very time-consuming.

Qin Long's mold casting method is different. It uses internal force to directly refine the spine into bone fluid and pour it directly into the mold prepared in advance, which can greatly increase the speed of the mold.

However, the pouring method has a fatal flaw, that is, the final quality of the weapon is slightly worse than the former.

"The strength of second-level weapons is not high. If they break after use, we will repair them for free." Qin Long muttered, took out the fine iron mold that had been prepared, and used his internal force to pour out the bone fluid in the alchemy furnace.

"Chichi..."

After a harsh sound, the prototype of the bone knife was ready.

In the small hut, the boiling bone fluid made the air hot. Qin Long stared at the bone fluid in the alchemy furnace with all his concentration, and his face turned pale.

It was impossible to smelt the spine, and it was not difficult to cast a weapon, but Qin Long did not expect that keeping the bone liquid from cooling in the alchemy furnace would be such a laborious task.

Now Qin Long is not as leisurely as he was at the beginning. He is just a Qi-training monk who has used a lot of energy to smelt bone beads. Now the energy in his body is about to be exhausted. It is not easy to persist until now.

There was a feeling of emptiness in the essence pool, and Qin Long knew that it was a situation where the essence was about to be exhausted.

There is less than half of the bone fluid left in the alchemy furnace. He originally wanted to cast all the bone blade embryos today, but I am afraid he can't do it now. Just when Qin Long planned to do it again tomorrow, the energy that was about to be exhausted

Suddenly it was retracted into the sea of ​​​​qi, leaving only the Yin and Yang fish stirring feebly in the alchemy furnace.

However, the spiritual energy in the Dantian suddenly appeared, replacing the internal force to control the bone fluid in the alchemy furnace and injecting it into the mold.

Qin Long was startled by this sudden change.

"Yes, I still have spiritual energy that I can use!"

Only then did Qin Long remember that he had more than just one kind of power in his body. Since the meridians were shaped, the fire attribute aura could already be used initially.

There is a large amount of spiritual energy stored in the Dantian, and all the knife embryos are finally cast before the bone fluid solidifies.

Qin Long's shoulders relaxed, and his body seemed to have lost all strength. He immediately collapsed and lay down among the messy blades, breathing heavily. He was so weak now that he didn't even want to open his eyelids anymore.

"No, I have to capture the feeling of using aura just now."

Qin Long knows the value of the spiritual energy in his body. The two powers can be used independently of each other, which is equivalent to having twice the cultivation level of ordinary people. If used properly, he can exert unexpected effects in battle.

The problem now is that Qin Long is used to using essence, and if he doesn't actively activate the essence, it will be like a pool of stagnant water entrenched in the Dantian. If things go on like this, he will only become overly dependent on essence and lose the effective use of essence.

Qin Long dragged his exhausted body up from the ground and sat down cross-legged. He formed mudra with trembling hands and silently mobilized the spiritual energy to swim around his body, imagining the technique of ghost fire entangling the body.

And he uses two minds at once, while contemplating the exercises, he uses yin and yang to absorb and transform the essence of heaven and earth.

"It turns out that the red lines on the body of the will-o'-the-wisp are not fixed. No wonder this meridian in my hand feels a little sluggish when controlling the fire attribute aura."

The mental method explained by Wu Jian did not mention how the red lines appeared. Only now did Qin Long discover that these red lines were gradually formed during the practice of the technique, and each person is different.

"It seems that the meridian in my hand is a useless meridian." Qin Long was a little regretful. The meridian he had worked so hard to shape could not fit the will-o'-the-wisp body, which gave him a headache.

Slowly opening his eyes, after adjusting his breath just now, the soreness all over his body has dissipated a lot. Looking inside the sea of ​​qi, after nearly midnight's rest, the originally depleted essence pool has been completely restored with the supplement of yin and yang fish.

Qin Long smiled bitterly and shook his head. This was the first time he felt tired since practicing Qi. In the past, there was no time limit for smelting refined iron spiritual materials. He could take his time, but smelting bone blades was urgent, because Qin Long still had

There are more important things to do.

Qin Long placed the demon wolf spines that he had previously removed one by one in front of him. He had just smelted a large number of second-level bone blades just because he was rushing to complete the work. Now was the time for him to really fight for himself.

Without the pressure of time, Qin Long was obviously much better than Qin Song this time, and soon more than a hundred second-order bone beads appeared in front of him.

However, Qin Long did not stop, but took out the Polygonum Iron and wrapped the bone beads. The Yin and Yang fish kept swimming on the surface of the Polygonum Iron, further smelting the bone beads inside.

As soon as those tiger-mouth-sized bone beads were put into the Polygonatum iron, they turned into white water and shrank rapidly. After a while, they turned into a small drop of white solution.

With the help of Huang Jingtie, Qin Long did a good job of not over-smelting the bone beads. This drop of solution has reached the level of the third-order high-grade.

Continuing to put the remaining bone beads into it, more and more solutions were added to the Polygonum Iron, and a thin layer accumulated at the bottom. After all the bone beads were exhausted, Qin Long gently controlled the Yin and Yang fish to narrow the Polygonatum Iron.

The mouth was sealed.

Looking at the full moon that had just risen in the middle of the sky, Qin Long gritted his teeth, reached out to grab the small Huangjing iron ball, swallowed it in his belly, opened the top of the alchemy furnace and jumped into it.

Bang!

The top cover of the alchemy furnace was closed, Qin Long sat cross-legged, concentrated his thoughts, and let the yin and yang fish refining and compressing crazily.

As the Yin-Yang Fish rotates rapidly, the dark-toned Huangjing Iron gradually becomes translucent, and the hard shell begins to soften.

This is a sign before the Huangjing Iron is refined, but Qin Long knows that with his current level of internal strength, it is far from enough to refine Huangjing Iron, and he has not thought about smelting it directly. Although Huangjing Iron is good,

But it doesn't suit him now. He has other plans for this move.

At this moment, Qin Long felt as if there was an extra fireball in his belly, burning him until his eyes were dizzy and his mouth was dry.

"No, if we continue like this and fail to smelt the inside of the Huangjing Iron together, I will faint first. I have to think of a way."

Thinking of the excellent isolation effect of essence, Qin Long made a thought and used essence to tightly wrap the Polygonatum iron ball to reduce the dissipation of heat.

"Chi chi chi..."

However, the progress of the matter was not as simple as Qin Long imagined. Although the essence could block the heat flow, he ignored the yin and yang fish.

With the help of the essence, the Yin-Yang Fish turned more and more cheerfully, draining away the essence wrapped around Huang Jingtie in an instant. If Qin Long hadn't been quick with his hands and eyes, he would have fallen into a state of exhaustion.

This really worried Qin Long.

There is only one Yin-Yang fish. After smelting spiritual materials, it cannot generate essence. The smelting itself consumes part of the essence. The remaining essence must not be squandered by the Yin-Yang fish.

"By the way, I'm a weapon refiner, so I can definitely use spiritual energy to practice qi!"

Seeing the pure spiritual energy entrenched in his Dantian, Qin Long had an idea. His preconceived notions made him fall into a misunderstanding, that is, only yin and yang fish can be used for weapon training. Little did he know that a real weapon refiner would be the first choice for weapon training.

The method must be spiritual energy flame.

The pure fire-attributed spiritual energy covered the surface of Huang Jingtie, and then wrapped all the remaining essence outside. Qin Long used the will-o'-the-wisp spirit to directly detonate the fire-attributed spiritual energy in the Dantian.

"boom!"

A slight muffled sound came from Qin Long's lower abdomen, and a spiritual flame suddenly erupted from his Dantian.

"Hiss... so hot!"

Qin Long gasped because of the high temperature of the flames. It was extremely dangerous to detonate the spiritual energy in his Dantian. If Qin Long's Dantian was not full of essence, it would be difficult to be harmed by the spiritual energy of the same realm. I am afraid he would have turned into a corpse by now.

.

"Refining!"

As Qin Long gave a soft drink, the spiritual energy flame turned into a red flame vortex, engulfing Huang Jingtie entirely. The previously busy Yin and Yang fish returned to the meridians and could only continuously provide Qin Long with energy.

The smelting speed of the aura flame is obviously not as fast as that of the Yin Yang Fish. Fortunately, the Huang Jing Iron has been refined a little. Under the continuous burning of the flame, the Huang Jing Iron Ball finally gradually turned into a translucent golden ball.

"It's done!"

Qin Long was slightly happy when he saw this. The material of Huangjing Iron is very special. If it can be completely smelted, it will turn into an almost transparent golden yellow liquid. The translucent appearance now is the limit of what he can achieve.

Through the blurry surface, Qin Long could see that the bone liquid in the refined iron ball had begun to boil and its volume had also reduced a lot. This is what it looks like when the bone liquid vaporizes.

Continuing to increase the firepower, Qin Long removed the spiritual energy flame until the bone liquid was completely vaporized, and the Huangjing iron ball was held up in the Dantian by the spiritual energy, resembling a golden elixir.

As the temperature dropped, the Polygonatum iron sphere gradually returned to its original opaque appearance, and the vaporized bone fluid gradually condensed. You could still hear the sound of water coming from inside when it was shaken gently.

"wind!"

Qin Long controlled the fusion of spiritual energy, and a breeze came out of his Dantian. His lips were slightly opened, and bursts of hot air were exhaled from his mouth.

Under the constant blowing of the breeze, the Polygonatum iron beads in the Dantian finally turned back to their original dull yellow color. The sound of liquid no longer came from the shaking, but turned into a heavy muffled sound.

Qin Long nodded with satisfaction. So far, everything has gone as smoothly as he imagined.

Qin Long turned the yin-yang fish again and separated the ball nervously. A small white semicircle hit the bottom of the alchemy furnace with a clanging sound.

Qin Long picked up the small piece of bone, and the hardness from his tentacles made him somewhat firm in his guess.

Qin Long opened the alchemy furnace excitedly, and a dazzling light came from the window. The full moon that originally hung high in the sky had turned into a rising red sun. Qin Long raised the bone fragment in his hand and looked towards the rising sun.

In the red glow, the smooth bone was reflected red, but in this red, countless yellow light spots shone like stars in the sky.

Seeing this yellow starlight, Qin Long was so excited that he almost yelled. He suppressed his excitement and picked up a long knife on the ground and chopped it into the bone fragments.

"Crack!"

The hard second-level bone blade was instantly broken into two pieces, but the bone fragment was unscathed, not even a gap was left.

"Fourth-level low-grade spiritual material! It's really a fourth-level low-grade spiritual material!"
Chapter completed!
