Under Gu Chensheng's constant blowing, these powders were slowly distinguished from the black ore.

This kid...

Xuan Lao and Emperor Qiu immediately understood Gu Chensheng's intentions.

Was it intended to be used off-the-field?

It turned out that just now, after Gu Chensheng noticed the abnormality in the black stone, he even stopped the flame of the furnace, and took advantage of the gap when the black stone was recondensed, and used his spirit to record those perceived abnormal parts one by one.

If it was only through the means of the refiner, with the help of flames to take out the impurities, with Gu Chensheng's current strength, even with the assistance of the spirit, it would be absolutely impossible to do such a thing that required experience.

This has nothing to do with strength, it's just that he doesn't have the foundation of a refiner yet.

Because the liquid slurry is really difficult to control, Gu Chensheng can't grasp how to use the difference in flame temperature to make these two substances with different melting points fundamentally separate.

So, by observing the black stone, he had the rough scene just now.

I can't do anything about the liquid state, but what about the solid state?

As long as you are knocked into powder, even if it will be a little wasteful, the part of Otogi in the black stone has been successfully separated.

With such a whimsical idea, Xuan Lao was not only surprised, but also sighed.

The method is very simple, except for a certain waste of materials, this is actually a method that ordinary people who can swing a hammer can do.

"I can't imagine that this little guy has never refined the method so simple and rude..."Emperor Qiu sighed.

"Simple... Rough..."Xuan Lao repeated these two words, and then fell silent, not knowing what he remembered.

Here, after Gu Chensheng separated Yimu from the black stone, he first pondered for a moment, and then gave up extracting all the ore in this way. Although he was only studying the refining method of Thousand Forging Exquisite Dragons this time, and he didn't think about achieving any results with this, it would be a bit too stupid for him to waste his time on this in vain.

"Forget it, the hardness of this ore is not bad. ”

Thinking about it, Gu Chensheng waved his hand, threw those black stone powder slags into the furnace, and gently slapped his palm a few times, and then the true qi surged again, and the flames in the furnace rose in an instant, slowly melting the black stone into a solution.

He looked at the furnace closely, but his eyes were fixed on the one in front of the others.

This kind of blatant plagiarism and undisguised style, Bai Ningshuang and Zhong Qing'er on the side blushed a little for him.

As for Gu Chensheng, he is still not disturbed by the environment.

After looking at the specific refining methods of several people around him, he simulated it again in his mind, and after confirming that there was no logical deviation, he raised his hand and threw another material on the table into the furnace.

"Huh? This kid. ”

Gu Chensheng's move once again attracted the attention of Emperor Qiu and Xuan Lao.

"Just one ingredient to put in the Purple Flame Fruit to raise the temperature of the flame, what is he going to do?" Bai Ningshuang frowned and muttered, even if she was not very proficient in refining, but the knowledge of words she learned from the academy, she also knew that this kind of refining method definitely did not exist in any teacher, an anthology.

"This little fellow may really have some whimsy, but the old man is curious to see what he can do in the end. Xuan Lao stroked his beard lightly, and watched Gu Chensheng really grab another piece of material after putting in the Purple Flame Fruit and throw it into the furnace.

"The bone marrow of the red fire beast? This thing is indeed not easy to refine with ordinary flames, but what kind of exquisite dragon is to be refined with black copper ore and the bone marrow of fierce beasts? And if this continues, I am afraid that if you can't wait for the result, the black copper ore will have problems. Xuan Lao looked at Gu Chensheng's whimsical behavior, and for a while he couldn't figure out what this kid was thinking, but with his experience, he could see that adding to the furnace of the Purple Flame Fruit would soon raise the temperature to the point that the black copper mine could not bear.

In fact, Xuan Lao did not have too many materials to test in this test, except for the ore used to condense the exquisite shape of a thousand forges, there was another one that was not very inconspicuous, and even said that it was dispensable in smelting.

That is the stamen of the Wandye flower.

The reason why it is dispensable is that most refiners do not deliberately spend time coloring the product when they practice.

Normally, the place where this spiritual material is most useful is the cloth shops in the various stores, and the cloth dyed and woven with this stamen is not only brightly colored, but also extremely difficult to fade.

On the second floor of this Tianji Pavilion, there are many people who wear clothes that are sewn from the fabric dyed by the stamens of Wandye.

But this time... Because it is Xuan Lao's exam question, whether these refiners are for the sake of face or to show the advantages of the thousand forging exquisiteness they have tempered, they will definitely not miss the opportunity to use the Ten Thousand Dyeing Flower for dyeing, and the closer to success, the more people's attention will be relaxed, so the second problem given by Xuan Lao is to test the concentration of the refiner.

Of course, the impact of this kind of final moment of joy, anger and frustration on his state of mind is not something he can consider, after all, in Xuan Lao's opinion, a refiner who can't even control his own emotions is not a real refiner at all.

However, it was such a dispensable material that was grabbed by Gu Chensheng, and then thrown into the furnace without hesitation.

As the temperature gradually increased, the flames in Gu Chensheng's furnace gradually turned purple, and the stamens of the Ten Thousand Dyeed Flowers only lasted less than two breaths under this high temperature, and they turned into scorched paste in an instant.

The few people who paid attention to Gu Chensheng shook their heads helplessly, this was clearly fooling around...

Bai Ningshuang was a little breathless, to be honest, if it was replaced by her a few days ago, the little princess would not believe that she would actually have such irritability because of someone's behavior.

She wasn't worried that because of Gu Chensheng's indiscriminate anger, it would affect Emperor Qiu's impression of them.

Bai Ningshuang's move was purely to make Gu Chensheng ridiculed by these refiners after a stick of incense, especially the eldest brother of Cheng Li, who had just revealed his identity.

However, before she could take a step, there was a soft sound in her ears.

Bai Ningshuang looked back and found that Xuan Lao was staring at Gu Chensheng's side, to be precise, staring at the furnace, and a hint of joy flashed in his eyes.

"Is something wrong?"
