Taking out more than a dozen different kinds of spirit grass, Elder Taishang put a flame stone under the Dan furnace again, and then turned back to Qin Lang and said, "I'll refine the Dan once, you carefully observe and perceive it on the side, tell me your feelings after refining the Dan, and I will ask you some basic questions again to judge whether you have the potential to become an alchemist!"

Seeing Qin Lang nod, a spiritual power appeared in the palm of Elder Taishang's hand, lit the flame stone, and threw a spirit grass into the Dan furnace, as the temperature rose, the spirit grass gradually turned into a rolling green medicinal liquid, and a large number of black impurities were removed, and when they were discharged outside the Dan furnace, the medicinal liquid became thicker and greener.

Immediately afterward, Elder Taishang threw another spirit grass into the Dan furnace again and continued to repeat the previous steps.

Qin Lang stared intently at Elder Taishang throwing one spirit grass after another of different colors into the Dan furnace, carefully feeling the temperature of the high and low, with a look of relief in his eyes, and nodded slowly.

Judging from the selected spirit grass, what Elder Taishang refined should be the most ordinary first-grade spirit pill, the Blood Returning Pill.

According to the Dandi Holy Book, what Elder Taishang is doing now is the purification step in alchemy, and the higher the purity of the extracted spirit grass, the higher the quality of the spirit pill refined at that time, and the better the effect!

Qin Lang judged that the concentration of the spirit grass purified by Elder Taishang was almost eighty percent, and it should be able to refine a high-grade spirit pill.

After purifying all the spirit grasses, Elder Taishang fused the medicinal liquid in a specific order, and when it was fused to the sixth medicinal liquid, Qin Lang frowned slightly, according to the description of the Dan Emperor's Blood Returning Pill in the Holy Book, it seems that what should be fused now should be another medicinal liquid, right?

Soon, Elder Taishang had already fused all the medicinal liquids, and the rich medicinal fragrance came out from the Dan furnace, and the crimson spirit pills gradually took shape in the Dan furnace.

"Close!"

With a low shout from the Supreme Elder, twelve crimson Blood Returning Pills flew out of the Dan furnace and fell into his hands.

"Well, that's good. This time it's a full pill, and there are even two high-grade blood return pills!"

Elder Taishang nodded with satisfaction, this time he was at the highest level.

"In the process of my alchemy just now, do you have any discoveries or questions to ask?"

Putting the Blood Returning Pill into a porcelain bottle, Elder Taishang looked at Qin Lang with anticipation.

"In alchemy, the most important thing should be the purification of the spirit grass and the final order of the condensation. ”

Qin Lang slowly spoke:

"Purification is related to the quality of the final elixir, and different spirit grasses have different temperature requirements for the flame because of their different attributes, if you want to purify the spirit grass higher, you must first understand the properties of the spirit grass, and at the same time, accurately control the temperature of the flame when purifying, without the slightest deviation!"

"Ning Dan is the most important step before becoming a Dan, once the temperature control of the flame is not enough, or the order of Ning Dan is different, it will lead to the failure of alchemy, and the success will fall short!"

From the practice of Elder Taishang's alchemy, coupled with what he learned from the Dandi Holy Book, Qin Lang summed up in his own words and talked eloquently.

"Yo, the kid is good, and the summary is in place!"

Elder Taishang's eyes lit up, Qin Lang, this kid seemed to have a little talent in alchemy.

"However, it seems that Elder Taishang had a bit of a failure when he fused the medicinal liquid just now!"

Qin Lang's next words made Elder Taishang stunned, and instantly pulled down an old face.

He has been alchemy for decades, he has extremely rich experience, and the process and result of alchemy just now are extremely perfect, this kid has never even practiced Dan, and he actually said wildly, saying that he had a failure when he fused the medicinal liquid?

It's a class axe!

I don't know how thick the sky is!

"Young Master!"

Yun'er hurriedly reminded Qin Lang in a low voice, Elder Taishang is a first-class alchemist, Qin Lang has just started to learn the Dan Dao, and it doesn't seem like a good thing to say this directly about Elder Taishang?

"Tell me, when I fused the potion solution, what did I do wrong?"

Elder Taishang suppressed the anger in his heart and looked at Qin Lang coldly.

This kid was originally looking for himself to learn Dan Dao, but now it's good!

Even pointed out to himself in turn!

Today, if he can't say why, he must educate him well!

"When you fuse the sixth medicinal liquid hemostatic grass, you should replace it with the tenth kind of green moon flower, so that the medicinal effect of the hemostatic grass can be better fused by the other medicinal liquids to improve the quality of Cheng Dan!"

Qin Lang didn't seem to hear the anger in Elder Taishang's mouth, and directly pointed out the problem he had discovered just now.

"What did you say!"

Elder Taishang froze, stunned on the spot, his eyes widened.

"Elder Taishang, don't be angry, my young master is straightforward and fast-talking, and he doesn't mean anything else!"

Yun'er was anxious, thinking that Qin Lang's words had completely angered Elder Taishang, so she hurriedly pleaded.

"Yes, the modulation can be better integrated, why didn't I think of it!"

Muttering to himself, Elder Taishang's eyes flashed with excitement, and under Yun'er's surprised gaze, he quickly took out a medicinal material for refining the Blood Returning Pill, and began refining it again according to the method Qin Lang said.

Soon, the medicinal incense came out again, and twelve crimson elixirs flew out of the Dan furnace and landed in the hands of Elder Taishang.

"Twelve full pills, and all of them are high-grade spirit pills!"

Trembling his hands, Taishang Chang was very excited and choked up.

Qin Lang casually pointed out a mistake, he actually refined a furnace of high-grade spirit pills, which he had never done before!

"Let's go!"

After a while, Elder Taishang, who had finally regained his composure, took a deep look at Qin Lang and sighed.

"Elder Taishang, the young master was unintentional just now, don't be angry, didn't you praise him for summarizing it well just now?

Seeing that Elder Taishang asked Qin Lang to leave, Yun'er suddenly became anxious and hurriedly begged bitterly.

"Alas, it's not that I don't teach him! At my level, I'm not qualified to teach him!"

Elder Taishang was in tears, he originally taught Qin Lang by himself, but it turned out that Qin Lang instructed him, how could people continue to teach!

Obviously, he knows how to make alchemy, and he came over to let me teach, deliberately beating me in this old face?

Elder Taishang really wanted to cry, the "surprise" that Qin Lang gave himself today was really too big!

In fact, Elder Taishang really misunderstood Qin Lang.

Although the theoretical knowledge is extremely rich, Qin Lang has no actual experience in alchemy, and there is still a big gap between his alchemy level and him.

"Well, I'm not qualified to teach him!

Seeing the frustration on the faces of the elders and young Taishang, Yun'er was a little dumbfounded for a while.

Elder Taishang actually said that he was not qualified to teach the young master?

Could it be that the mistake that the young master pointed out just now turned out to be right?

When will the young master know how to do alchemy?

Blinking a pair of beautiful eyes, Yun'er's willow eyebrows were slightly furrowed, and her little face was full of confusion and incomprehension.

"Farewell!"

Qin Lang smiled faintly and did not explain.

Having seen Elder Taishang's alchemy with his own eyes, Qin Lang was already clear in his heart about his strengths and weaknesses in the Dan Dao.

He knew that Elder Taishang just couldn't accept it for a while, and when he calmed down, he would be able to understand that it was the Dan Fang's problem, not that the level of alchemy was inferior to his own.

At the same time, the Ye family hall.

Ye Xuan sat in the position of the head of the family, and two sturdy men stood in front of him.

"Done?"

Ye Xuan grimaced and spoke coldly.
