"One ?!!!" When Chemir heard this, his expression was wonderful.

Ordinary first-grade alchemists can refine it once, and second-grade alchemists can refine it at least two or three times, what do you mean by once???

Otto on the side walked over, patted Xiao Yan's shoulder, and comforted: "Little brother, don't worry, there is still time." This time, the assessment is to refine the Black Iron Spirit Leaf, not to let you refine it once, but to improve the purity through continuous and repeated refining. ”

When Chemir heard this, he suddenly realized, it turned out that what he had just said was not clear enough, and there was ambiguity, and he hurriedly explained: "Because of the special nature of the Iron Wood Spirit Leaf, the difficulty of refining each time will be several times that of the previous one, even if it is the strength of my four grades, it can only be refined ten times repeatedly." If you do more, you can only do useless work. ”

Refining medicinal materials is nothing more than to obtain high-purity medicinal materials by means of flame burning to decompose, and then sublimation, crystallization, filtration, extraction, separation, distillation, dialysis and other methods.

But no matter what, it is impossible to obtain 100% medicinal substances from refining, just as the purity of gold is at its highest of 98K and infinitely close to 100.

And the more times you refine, the higher the purity, and that's right.

Xiao Yan tilted his head, confused, took the wooden box and walked into the small black room again, looking at the pure white powder in the wooden box, he couldn't help but fall into deep thought.

"Can this be refined? Won't it be ruined if you practice again? ”

"Could it be that the Alchemist Guild of the Gama Empire has a special method to teach, which can make the purity of the Black Iron Spirit Leaf reach a true one hundred percent?!!

With a flicker in his eyes, Xiao Yan's heart instantly rose to a competitive spirit, and he immediately took out the alchemy furnace and began to study it.

Soon, time passed minute by minute, and thirty minutes later, it was Liu Ling who came out first without suspense, first glanced around, and then looked at the small black house where Xiao Yan was, and found that no one came out Liu Ling showed a sneer.

Soon after Liu Ling came out, a light and agile shadow quickly flashed out of the black curtain, and when she looked at Liu Ling, who was standing in the hall early in the morning, her delicate pretty face suddenly showed a touch of disappointment.

Slowly came to the center of the hall and muttered, "Brother Liu." I didn't expect you to be so fast. ”

"Hehe, the little princess is not slow." Liu Han said with a smile.

"Hmph. Although you are earlier than me, the medicinal materials you have refined may not be as pure as mine! Raising her snow-white jade fist at Liu Ling, the little princess snorted lightly.

Soon, more and more alchemists came out one after another.

As the black curtain continued to lift, the sand in the hourglass was about to be completely poured. However, Otto and Chemir's brows were furrowed tightly, because Xiao Yan hadn't even come out yet.

"He's all left."

"Why is it so long?" Chemir was also puzzled, this has been too long.

Just when Chemir announced that the time was up, Xiao Yan hadn't even come out yet!

Chemir sighed, walked to the small room where Xiao Yan was, and whispered, "Little brother, the time is up, no matter what, you should come out first." ”

As soon as the voice fell, the black curtain was lifted, Xiao Yan shook his head and walked inside with a dejected face, as soon as he came out, Xiao Yan asked very curiously: "Does your Alchemist Guild have any special methods?" No matter how you look at this Black Iron Spirit Leaf, it can only be refined once. ”

Xiao Yan's voice was not small, and the other alchemists also heard it.

"Once?"

"Hahahaha, I thought he just didn't wear an alchemist's robe, but it turned out that he didn't."

"I can refine it once when I'm still an apprentice, so don't go too far through the back door."

And at this time, hearing that Xiao Yan was like a hillbilly, many alchemists standing next to him laughed even more.

Chemir shook his head, patted Xiao Yan's shoulder and comforted: "It's okay, you are still young, and you will have a chance in the future." ”

Only Liu Ling, who hated Xiao Yan the most, frowned, because he knew that even if Xiao Yan was weaker than himself, it would be impossible to refine it only once.

Moreover, Liu Ling heard that Nalan Yanran said that Xiao Yan also refined a third-grade elixir for the old man Nalan Yanran. That is, Xiao Yan is at least a third-grade alchemist, how can he only refine it once.

"Brother Liu Ling, why do you pay so much attention to that person?" The little princess Yue'er found that Liu Ling had paid attention to Xiao Yan several times, curious questions.

"He's at least a third-grade alchemist." Liu Ling said.

Yue'er was also surprised when she heard this, and her eyes widened at Xiao Yan. The three-grade alchemist refines it once? How is this possible. Did he lie on purpose?

Chemir didn't say anything more, walked to the center and said, "This is a purity measuring instrument that our Alchemist Guild has invited some famous casters to build. It is an accurate measure of the purity of the material you have extracted. ”

Chemir stroked the swarthy machine, pointed to a groove, and said, "Here, this is where the test materials are placed, and the score is tenth." 10 points are the highest, 1 point is the lowest, and 4 points are passing. You have said it a few times. ”

"Liu Ling, you start first."

Liu Ling calmly came to the side of the testing machine under the gaze of everyone, and then took out a jade bottle from the ring and poured out some gray-white powder into the groove, and smiled at Chemir: "The strength of the juniors is limited, and they can only be refined six times. ”

As soon as Liu Ling said this, everyone in the hall gasped, and then there was an uproar, not only the people below but also Chemir and Otto, who couldn't help but glance at each other in surprise.

To be able to refine the Iron Wood Spirit Leaf five times, it would take at least the peak strength of a third-grade alchemist, six times?!!! This is a terrible firefight.

In other words, Liu Ling's fire control power is already equivalent to four grades.

After the light on the screen flickered for a while, a huge seven characters slowly appeared.

"Seven points, congratulations on passing the test." Chemir smiled.

Liu Ling smiled, and then dodged to the side. His eyes glanced at Xiao Yan who was standing at the back, he didn't care why Xiao Yan was lying, but the result would prove that he was the strongest!

At this time, Xiao Yan's brows were furrowed, and his expression was extremely strange, as if he had seen something he couldn't understand.

Then came to the little princess Yue'er, and it was a pity that although the little princess had also been refined six times, her purity was a little lower than Liu Ling's.

Seeing more and more people coming forward to test the purity, Xiao Yan couldn't help but sigh, I finally understood what the problem was.

Until the end, after everyone had finished testing, Chemir looked at Xiao Yan and said softly, "Little brother Xiao Yan, you can also come up and take a test." ”

Xiao Yan nodded lightly and slowly walked to the testing table with a small wooden box.

Otto asked, "Did you only refine it once?" ”

Xiao Yan nodded and said calmly, "Yes, only once." ”

Just when everyone below was snickering, Chemir and Otto saw Xiao Yan open the wooden box and exclaimed, "Pure white?!!! ”

The screen suddenly erupted with a dazzling golden light, and the huge cross on the screen was like a big mouth, pumping on the faces of all the jokers.

Xiao Yan looked at Vice President Chemir with a strange face, and asked, "Vice President, you can extract the medicinal materials from the medicinal properties at one time, why do you want to refine them ten times?" ”
