The scene in front of him made Liu Chen feel very familiar.

When Qin Yu and Elder Xu Lai were refining the pill in Tianfeng City, wasn't that exactly the case in the steps of selecting materials?

Everyone was not optimistic about Qin Yu and felt contemptuous of Qin Yu's pretentiousness from the bottom of their hearts.

However, in the end, Qin Yu won the Dan fight as if he had created a miracle, which shocked all those who were not optimistic about Qin Yu before.

It was that experience that made Liu Chen admire Qin Yu's alchemy attainments.

At this moment, Qin Yu faced Bai Feng and Yan Wuji's disdainful gaze and tone, and he was still as calm and calm as last time.

This made Liu Chen's anger towards Bai Feng in his heart dissipate a lot: "Qin Yu must be sure, otherwise he would not be so calm." ”

It was also at this moment that a fiery faint blue flame rose from Qin Yu's palm as the sound of 'bang' flames rolled.

Bai Feng, who was waiting to announce the result of the failure to advance, was comfortably leaning back on the chair and taking a sip of tea, just took a sip, but suddenly saw the dark blue flame in the corner of his eye......

I saw him lose his voice in astonishment: "The faint blue flame, the intensity of this flame is fifty percent stronger than the power of the ordinary alchemist's Dan fire!"

"What is there to be surprised about. ”

Yan Wuji said slightly, but he was not in a hurry: "He just cultivated a special fire-based exercise, and this flame is transformed from that fire-based spiritual power, according to the power of the flame, it is also a Xuan-level mid-grade exercise." ”

"There are two or three copies of the Xuan-rank mid-grade exercises of the fire system in my Yan clan's royal family, Vice President Bai Feng, if you are willing to re-cultivate, I can also give you a copy. ”

Bai Feng, as the vice president of the Cangyan Association and a three-star alchemist, how could he lose his temper because of a mid-grade fire technique?

Instead, Bai Feng thought of the rumor that the Qin family had discovered a strong man's relic's mansion some time ago, and it was in that strong man's relic's mansion that the Qin family obtained several Xuan-level martial arts and techniques, and shared them with all the forces and families in the Northern Regions that were close to the Qin family.

Although the Qin family has a big business, the family is not wealthy, because Qin Yaowu is an honest official, and it is said that even the expenses and operations of the family have to rely on the support of merchants.

How could such a family in charge of military power have too many Xuan-level exercises and martial arts?

Bai Feng thought of the exercises that Qin Yu had cultivated from the faint blue danhuo that Qin Yu had used, and from the exercises that Qin Yu had cultivated, he thought of the rumors of the strong man's relic.

Then I thought of Qin Yu's previous knowledge and talent in refining medicine, maybe, maybe Qin Yu also obtained some rare medicinal materials, pills, or alchemy classics in the strong man's mansion!

It was precisely because of this that Bai Feng was so excited that he suddenly lost his temper and squirted out a sip of tea on the spot.

For any alchemist, whether it is a rare medicinal material, a pill or a medicine refining book, all of them have a fatal temptation.

As a result, without Qin Yu's knowledge, Bai Feng had already had a 'voyeuristic heart' in his heart about the non-existent powerhouse treasure that Qin Yu had obtained.

Bai Feng, whose IQ is anxious, is extremely shrewd at the moment, but his eyes are in a few circles in his sockets, and he does not reveal any abnormality, and he hurriedly nodded to Yan Wuji and said, "What Prince Wuji said is that I made a big fuss. ”

Yan Wuji didn't care too much, he didn't notice Bai Feng's careful thoughts, and he still had that gentle smile.

In front of the medicine refining table, Qin Yu was not slow to manipulate the Ghost Flame to purify the medicinal essence of more than twenty kinds of medicinal materials he had selected.

He did not follow the usual alchemy procedure, and threw all the medicinal materials into the furnace to melt the pill with the help of the essence of the medicinal materials after purification.

Instead, he carefully packed each purified medicinal essence into a jade bottle on the side.

However, in about half an hour, twenty-eight kinds of medicinal materials, except for the petrified fruit, all the medicinal materials have been purified, the technique is unique, and the experience is extremely sophisticated, which has been praised by Liu Chen.

"Hehe, this king wants to see how you deal with this petrified fruit!"

Seeing Qin Yu staring at the petrified fruit and frowning slightly for a while, the corners of Yan Wuji's mouth couldn't help but peck a chuckle.

The most difficult step in refining the Stone Muscle Pill was how to deal with this petrified fruit, and Liu Chen, who was watching from the sidelines, frowned at the moment, with his current ability, he couldn't find any way to deal with this petrified fruit.

However, after a moment, Qin Yu suddenly showed a confident smile, turned back to Liu Chen, and said, "President Liu Chen, you have to watch over it next, and see how I broke this unsolvable petrified fruit." Your theory of strong acids is not perfect, so I'll show you another way to use strong acid herbs. ”

He took a metal container and poured the purified medicinal essence of the six flavors into the container in succession.

After the different colors and exuding a strong smell of medicinal essence were diluted together, they suddenly had a violent reaction, and the bubbles kept rising and then bursting, and a lot of the liquid medicine splashed on the stone platform.

The place where the stone platform was eroded by this splash of liquid medicine emitted wisps of choking smoke, and the stone platform was eroded into tiny holes.

It can be seen that these six kinds of liquid essence have a strong acid corrosive effect!

Seeing that the mixture of medicinal liquids reacted violently, Qin Yu threw the petrified fruit that was like a pebble into it.

Zi~Zi~

When the petrified fruit was thrown into the container, it suddenly made a piercing sound, and its skin slowly became soft under the erosion of strong concentrated acid, but it did not damage the medicinal spirit contained in the petrified fruit.

"Sulfuric acid grass, eroded wood quicksand, and the essence of four medicinal materials such as Hanxing vine, the mixed medicinal liquid is blended, and it actually has such a stable concentrated acid erosion effect!"

"This strong acid effect can soften the medicinal materials very well, and does not damage the spiritual energy of the medicine contained in the medicinal materials!"

President Liu Chen suddenly realized that the petrified fruit after being soaked in this mixed medicinal liquid would be very easy to be refined and purified by Danhuo!

At this moment, he finally understood the meaning of what Qin Yu said just now.

This is another way to use strong acid herbs!

Since strong acid medicinal materials with neutralization can help repel the impurities of the essence of the medicine and help improve the quality of Cheng Dan, why can't the method of soaking with strong acid help the alchemist purify and refine the medicinal materials more easily?

It was as if a new academic door for alchemy had been pushed open by Liu Chen, and he was obsessively savoring Qin Yu's every move just now, and the type and amount of medicinal materials used in the mixed medicinal liquid.

"Genius, no, it should be a demon! He is definitely a demon in the world of refining! How did he come up with such a method of dealing with medicinal materials such as petrified fruits that are difficult to rely on Dan Fire to refine and purify!"

When Liu Chen pondered the theory of medicinal properties and pharmacology, Qin Yu had already started the process of refining the Shiji Dan.

After the petrified fruit was soaked in the mixed concentrated acid liquid for about a long time, the whole body swelled and became extremely soft, not to mention Qin Yu's ghostly flame demon fire, even the ordinary Dan fire of a one-star alchemist could easily purify and refine it......
