Sun Yunhao was a little worried that Uncle Kuang would evaluate him in a month, if he refined too few materials and the chance of failure was too great, maybe Uncle Kuang would drive him down from the position of refiner and let him do something that no one wanted to do.

Sun Yunhao glanced at the little ding and whispered, "Otherwise, try it with this little ding!" ”

Sun Yunhao carefully put a piece of waste copper ore into the Dan furnace, and then closed the lid of the Dan furnace, waiting for a miracle to appear.

According to Xiaoding's magical effect, as long as it is a spiritual object with aura in the body, as long as the aura is not saturated, the aura can be raised to the peak, that is, the upper limit of the aura. Each improvement takes more time.

For example, a defective elixir and a low-grade spirit stone, under the action of this small ding, can also become a high-grade elixir, or a high-grade spirit stone. Moreover, it can also make the aura of cinnabar even more. If this is the case, then the inferior metal that is refined is similar to Cidan, and it can be refined with Xiaoding and turned into ordinary metal.

Two hours later, Sun Yunhao lifted the lid of the Dan furnace with a look of anticipation.

Sure enough, the aura contained in these refined iron has obviously increased a lot, and the color is more vivid. Compared to the refined copper he had refined before, this one looked a little better.

Although Sun Yunhao was not sure if Xiao Ding could really make these copper essences go to the next level, he didn't dare to try rashly, for fear that there would be too much aura contained in these copper essences, which would make Uncle Kuang suspicious, and it would be worth the loss.

Sun Yunhao took out this copper essence from Xiaoding, and put another piece of copper essence that had been quenched back into it.

This time, it took him more than half an hour to take out the copper essence from the copper furnace.

Because the consumption of divine consciousness was too large, and Sun Yunhao, who had a headache, finally breathed a sigh of relief and slept well.

Two whole days! After a good night's sleep, Sun Yunhao's consciousness also returned to its original state. Now there are only seven or eight days until a month.

However, with this Xiaoding, Sun Yunhao is not afraid at all.

He simply threw all the spirit stones in front of him, and performed a "levitation technique" that made all the spirit stones suspended in mid-air. Then, he shot out a spiritual aura in each hand, and hit the two dragon head statues respectively, the two dragon head statues opened their mouths, and an arm-thick flame erupted from the statues' mouths and landed on the stone, burning the stone into drops of liquid, suspended in mid-air.

Sun Yunhao didn't care how long these copper essences burned in the earth fire, he condensed these copper essences together, forming five or six small balls.

It took a lot of effort to gather all these liquids together, Sun Yunhao withdrew control of the earth fire, and the two dragon heads no longer spewed flames.

Then he injected an aura into the dragon head of the stone chamber, and with the infusion of the aura, a stream of aura gushed out from the dragon head, and soon the aura filled the entire pool.

Sun Yunhao controlled these liquids, and quickly sank into the pool, and with a "zla" sound, a stream of white gas came out, and pieces of copper ore appeared in the pool.

After this set of processes, Sun Yunhao spent seven or eight hours, and by this time, his forehead was covered with sweat.

It doesn't matter if the spiritual power is lost, with a high-grade spirit stone in hand, it can be restored at any time. The only thing he could do now was to take a good rest and slowly regain his senses.

As for the final result, it was five or six pieces of pure copper ore with thin aura and dull color. There is also a dark brown one, and the aura contained in it is also extremely thin, far from reaching the color that gold essence should have.

This was because Sun Yunhao had too many purifications at one time, causing Jiang Chen's divine sense to be unable to be accurately controlled.

However, Sun Yunhao didn't care, because he had Xiaoding in his hands. He put the scrap copper into the small ding, and kept it warm for more than an hour, before sitting down cross-legged again.

A month passed in a blink of an eye, and Sun Yunhao took the dozen pieces of refined copper ore and walked out of the forging room with confidence.

Senior Brother Lu was already waiting outside, and as soon as Sun Yunhao and the three arrived, the four of them directly stepped on the stone steps and went straight to the Hundred Forging Hall.

Nothing to say all the way. Sun Yunhao looked at Fang Fu and Ma Gao, and saw that both of them had anxious expressions. Obviously, the results were not very good.

They didn't see the slightest mood swing on Sun Yunhao's face, which made them even more worried. When Ma Gao was here, he thought the mountain road was very close, but now, he really hopes that this mountain road has no end.

However, just when he was anxious, the Hundred Forging Hall had already arrived.

In the Hundred Forging Hall, Uncle Kuang, who was a little fat, was still leaning on a Taishi chair, his eyes closed, as if he was resting.

But this time, it was very different, when Sun Yunhao and the others walked into the main hall, Kuang Chen's eyes suddenly opened.

"How much copper ore is smelted? Show me. Uncle Kuang didn't ask about the cultivation progress of Sun Yunhao and the others, but went directly to the point and began to check it.

Sun Yunhao took out the copper concentrate from the storage bag and fell to the ground in one fell to the ground, and then his eyes turned to the other two monks.

Sun Yunhao glanced at it and saw that the two of them had only refined eight or nine pieces, and most of them were refined garbage.

In front of Sun Yunhao, there are eleven refined copper, three of which are scrap copper, so his advantages are clear at a glance.

The reason why Sun Yunhao did this was that he was afraid that his performance was too good and that Uncle Kuang would see the flaws.

Originally, he just wanted to be on an equal footing with the other two and not be too outstanding, but now it seems that he still underestimated the strength of these two. It's just that I didn't expect that the purification technology of these two guys was so poor.

Ma Gao and Fang Fu were much simpler, their results were much worse than Sun Yunhao in terms of quantity and quality, and there was both shame and apprehension in their expressions.

Senior Brother Lu and Senior Uncle Kuang were a little surprised, and Sun Yunhao's performance was a little unexpected to them.

"Huh? It's a good thing, it's good! As he spoke, he took a piece of ore that exuded a faint golden light from Sun Yunhao's hand, played with it twice in his hand, a smile appeared on the corner of his mouth, and said to Sun Yunhao: "It seems that you are very talented in forging?" ”

"Sun Yunhao, thank you Uncle for your compliment, and this is also thanks to Uncle Shi's guidance." Sun Yunhao hurriedly slapped the sycophants that made him a little embarrassed.

"By the way, Senior Nephew Sun, can you tell me what method you used to make your success rate higher than that of both of them?" Uncle Kuang said with a smile.
