With the injection of Fan Li, the entire molten liquid took on a strange gray color, and all kinds of impurities mixed in it actually attached to Fan Li.

This is the quenching technique that only Qin Yan can use, and it is also the most profound technique in the alchemy technique, Unity.

The so-called unification is a kind of purification technique that has been handed down in ancient times, and the normalization technique is divided into nine layers, and Qin Yan uses the most basic ninety-nine to one, that is, to remove the impurities in the melt through ninety-nine-eighty-one different methods.

The most advanced thing is that the unification technique does not require eighty-one techniques, but only nine kinds of mudras can be purified, and the purity will reach more than ninety, but this technique is used by the ancient powers to refine the stars, and with Qin Yan's strength, it cannot be mastered at all.

And the ninety-nine to one he used was just used to refine the Thousand Star Stone, through the power of the isolation of mortal power, coupled with the differentiation of the Normalization Technique, the Thousand Star Stone would eventually reach more than ninety percent purity.

When the first handprint slapped on the stove, Qin Yan's stove suddenly emitted a colorful light, and it seemed that he had a tendency to fry.

"Oh no, it's going to be fried." Ni Feather whispered.

Qin Yan gave her a bright smile, and then, the light disappeared, and the furnace stabilized again.

Mu Longsheng on the stage saw Qin Yan's technique, and his eyes lit up, he had never seen such a strange technique.

"This little guy is a little strange, the current alchemy is all about the refiner separating the impurities with his powerful spiritual power, and he seems to rely on external forces, is this ......?"

Mu Longsheng pinched his beard and groaned.

Qin Yan didn't care about that at this time, all his mind had already been put into the molten liquid, and when his first handprint was taken, a small cloud of impurities had already floated out of the molten liquid, and was immediately absorbed by Fan Li.

At this moment, a muffled sound sounded, and a disciple's face suddenly darkened, because, he failed to purify, and the molten liquid of the Thousand Star Stone had turned into a charred black color.

He shook his head, saluted at Mu Longsheng, and retreated directly.

With the passage of time, some people continue to fail, and some people complete the purification in advance in order to avoid failure.

However, the quality of the purified Thousand Star Stone in their hands is not good, and they can only occasionally see the slightest streamer overflowing, indicating that the purification is only thirty percent or even lower.

One hour, two hours, three hours......

The people on the field have already completed the purification, and Ni Yu has barely purified to fifty percent under the situation of a large loss of spiritual power, which is relatively good.

Now, there are only four people left: Wang Changsheng, Qin Huangyu, Bai Yuxi and Qin Yan.

Sweat was already pouring out of the foreheads of the other three, and Qin Yan could only slap the handprints of Xuan Ao on the stove one by one.

Finally, Wang Changsheng couldn't hold on at first and stopped refining.

As the molten solidified, a stone shining with starlight appeared in front of everyone.

Mu Longsheng's eyes lit up, "Not bad, yes, it can be purified to sixty percent." ”

He glanced at Wang Changsheng approvingly.

Wang Chang let out a sigh of relief and stood there calmly.

Immediately afterwards, Qin Huangyu and Bai Yuxi had also completed the purification.

The purification of the three of them is about the same, they are all sixty percent, but in terms of quality and the flowing star sand in it, Bai Yuxi is superior.

The only thing left on the field was Qin Yan.

He was still beating the stove very calmly, and he didn't seem to be in a hurry at all, but his consciousness was always watching the situation of the three of them.

"Sixty percent, almost, I'll purify it to sixty percent, that's right."

Just as he was about to extinguish the flame of the furnace and let the Thousand Star Stone solidify, a voice sounded directly in his ears.

"Qin Yan, purify to ninety."

Qin Yan's hand shook, his handprints were almost wrong, and the entire furnace vibrated violently, as if there was a sign of an explosive furnace.

"I'll go, you don't bring this." Qin Yan heard that it was Song Qiu's voice.

At this time, his handprints had reached seventy, and the purification of the Thousand Star Stone had reached seventy, but Song Qiu's words made him form his handprints again.

Seeing that his old god was there, the others couldn't help but talk about it again, and Wang Changsheng and the three of them, Bai Yuxi, and the others and the two of them all looked at Qin Yan with disdain.

"Sensationalism!" Wang Changsheng snorted coldly.

Qin Huangyu also looked at Qin Yan with strange eyes, because he had already recognized the other party.

Only Bai Yuxi, looking at Qin Yan's gaze, there was a trace of strangeness.

Finally, Qin Yan's last handprint was completed, extinguishing the flame of the furnace, and he also let out a long breath.

I felt dizzy, after all, the unification technique still consumes a lot of spirit, and none of the eighty-one mudras can be wrong, otherwise, it will be a failure.

However, the doubts in Qin Yan's heart deepened, "How does he know that I can purify the Thousand Star Stone to more than ninety percent?" ”

"Qin Yan, open your furnace!" Mu Longsheng said.

Qin Yan stretched out his hand and slapped the stove open.

A dazzling light rose into the sky, and starlight appeared in front of everyone's eyes.

Dazzling stars flowed slowly over the main hall like quicksand, exuding a misty light.

Mu Longsheng, Bai Hanbing, and Qin Tianfang stood up directly, looking at all this dumbfounded.

Mu Longsheng couldn't say anything even more excited.

As a refining master, he knew that being able to produce such a spectacle showed that the purification of the Thousand Star Stone was at least more than ninety.

"Qin Yan, hurry up and take out the Thousand Star Stone after the thousand refinements." Mu Longsheng's voice trembled a little.

Qin Yan stretched out his hand and made a move, and a crystal crystal flew out of the furnace.

Among the crystals, the stars and sand flow, beautiful.

Mu Longsheng summoned the crystal into his hand, gently caressing the surface of the crystal, and couldn't put it down.

"It's really the crystallization of a thousand stars!" He whispered, as if he was afraid of waking up the flowing star sand in it.

However, although his voice was very soft, everyone in the audience gasped directly.

The so-called crystallization is the name of the purification of the material to reach more than ninety percent.

The disdain in Wang Changsheng's eyes disappeared, and his gaze at Qin Yan was already full of admiration.

Qin Huangyu was even more unbearable, he felt that his hands were trembling.

"Is this the genius of the Zong family? That once the most dazzling star had even reached such a state of refining. ”

Bai Yuxi's cold face showed a smile, and that smile was like melting ice and snow and a spring breeze.

Ni Yu looked at Qin Yan and muttered in a low voice, "Is this a genius?" ”

Qin Yan shrugged his shoulders helplessly, looking at everyone's eyes as if looking at monsters, although he was a little embarrassed, but the feeling of the stars holding the moon made him seem to have returned to the previous Zhongzhou years.

"Song Qiu, Song Qiu, what is your purpose in doing this?"
