After all, he is a dignified Dan King, his identity is respected, and others ask for Dan, but they are mostly trembling.

The pills he was willing to take out and sell, naturally few people were qualified to blame, so no one told him what he said.

Pills, in fact, are the same as decoctions for patients, no matter how good the prescription is, how perfect the decoction is, there is only one most important thing, that is, it can cure the disease.

A medicine that does not cure a disease is not a good medicine.

"This mistake, the old man admits it!" Mu Qiankun looked at Zhang Heng deeply, with a little more attention in his eyes.

Anyway, this kid does have some skills.

"However, this mistake is just a mistake in my concept, focusing only on the properties of the medicine and ignoring the pharmacology. Mu Qiankun shook his head and said, "I don't believe it, I will make mistakes in other aspects." ”

"And listen to me, if the seniors think what I said is wrong, although you can deny it. Zhang Heng smiled lightly and continued.

"If what I expected is good, the prescription used by the predecessors contains thirty-seven flavored medicinal herbs, including lark flowers, raw bone powder, painted soul mushrooms, and seven-pattern Tibetan cloud grass......

After speaking, Zhang Heng looked at Mu Qiankun.

"Am I right?"

"That's right. Mu Qiankun's eyes showed a little surprise.

Dan masters of his level have a common problem, that is, they like to change prescriptions!

Why?

This is the same as ordinary people learning, after undergoing a systematic cramming education, they can not only summarize a set of learning methods suitable for themselves, but also have their own perceptions.

And those who have learned to the highest level want to leave something to the world and change something.

In fact, there are many repetitive pills used in them, and the alchemy techniques are also jerky and redundant, so when you have your own perception, you can remove the excess medicinal materials and correct the bad alchemy techniques, so that the quality and success rate of the pills will also be greatly improved.

Mu Qiankun is known as the King of Dan, and he is highly respected, and a common Dan recipe like Ziyun Dan has naturally been improved countless times.

Before he alchemizes, he must first study the pill formula, and only after the study is understood, will he refine the pill, and if he feels that something is wrong, he will definitely revise it.

Of course, if there was that kind of Dan Fang that had been handed down from ancient times, or that was perfect in itself and could no longer be modified, then he would not have done it again, but judging from the backward cultivation environment of the earth today, this possibility was very small.

Therefore, the Danfang was improved by himself, and when Zhang Heng tasted all the medicinal materials and said them in order, he would show such a look.

His first reaction, could it be that his Dan Fang leaked out?

Danfang is the biggest secret of Danshi, and it is also the biggest taboo, how can it be passed on?

But when you think about it, you think it's impossible?

Zhang Heng came to the Purple Bamboo Forest for the first time, and he had only been in contact with Mu Qing before, and Mu Qing didn't even know the Dan Fang of the Purple Cloud Pill, so this was terrifying.

"You just looked at this pill and deduced my pill?" Mu Qiankun took a deep breath.

"Not bad. Zhang Heng nodded.

"Hiss!" Mu Qiankun gasped and swept away all his contempt for Zhang Heng, this junior in Dan Dao's understanding was terrifying!

Throughout the ages, how have you ever heard of such an amazing and brilliant person?

And Mu Qing's eyes were also full of brilliance, she grabbed the corner of her skirt with her small hand and looked at Zhang Heng fixedly.

All this is unbelievable to her.

Mu Qiankun saw that he happened to see his granddaughter's expression, and immediately coughed and said, "You deduced the Danfang, and it is not considered that you pointed out my mistake. ”

"Don't worry, senior, I haven't finished yet. ”

Zhang Heng pointed to the Ziyun Pill in his hand and said.

"The seventh step, put in the blue grass, the twenty-third step, put in the purple cloud flower, and finally when you become a dan, the predecessors add the water of the cold pool, right?"

"That's true. Mu Qiankun said.

"Seniors and think about it, the blue grass belongs to yin, and the purple cloud flower can create illusions, and the two assist, it forms the core effect of the purple cloud pill, through the yin qi, to hook out the inner demons, and then show it with illusions, so that the person who takes the pill can overcome, in order to make the two elixirs can be perfectly integrated, the predecessors deliberately use the water of the cold pool to make it quickly fuse, but you have forgotten a little, although the water of the cold pool can accelerate the fusion of these two elixirs, but its own cold qi will destroy the original structure of the elixir. Zhang Heng paused and said again: "The final result will be like this, after the elixir is refined, the cold qi is too heavy, and even if the cultivator has passed the inner demon, he will have a few days to expel the cold qi in his body." ”

Hearing this, Mu Qiankun closed his eyes.

When it came to his own Danfang, he didn't dare to be careless, but he simulated it over and over again in his heart, and sure enough, as Zhang Heng said, there was no deviation at all.

"However, if you don't use the water from the cold pool, what should you use?" Mu Qiankun opened his eyes and asked.

"It's simple, a little dew on top of the elixir. Zhang Heng pointed to the medicine fields on both sides, indicating that it was within reach.

"Dewdrops?"

As if there was a flash of lightning in Mu Qiankun's mind, he got up, simulated his Dan Fang again, and said dreamily.

"I see, I see, the dew drops are contaminated with the aura of the elixir, and they are natural, although they can accelerate the fusion of the blue grass and the purple cloud flower, although the speed is slower, but the victory is mild in nature, after becoming a pill, it will definitely not make people have excess cold in their bodies......"

Zhang Heng smiled lightly and said no more, King Dan is really King Dan, just a little bit thorough.

"The kid's alchemy method, without traces, is like a wild imagination, the old man thinks that the water of the cold pool is already cheap, but compared with the dewdrops, it is expensive, after all, this dewdrop is completely free of money. Mu Qiankun's eyes were full of solemnity, and he said in a deep voice: "This kind of alchemy method is unheard of, rare in the world, it can be called a stroke of genius, did you think of it yourself?"

"I'm the only one on earth who knows. ”

Zhang Heng said.

He made a pun on the earth, so naturally a lot of people knew, after all, in his world, this is just a little trick that everyone knows.

But on the earth, it has become a stroke of genius.

"Sure enough, it's a young talent. Even if he had any opinions about Zhang Heng in his heart, Mu Qiankun had to admit his talent, he sat down, sighed and said: "You have found out the two mistakes, presumably the third mistake really exists, you say it, the old man listens." ”

Speaking like this, it means a bit of admitting defeat in advance.

The three girls' original worries were swept away, and a little pride appeared on their faces.

As for Mu Qing, she was a little entangled.

"Could it be that he's really better than Grandpa? Isn't it? How is that possible?"

She muttered in her heart, but the balance unconsciously tilted towards Zhang Heng's side.

"The third mistake is not actually a mistake, but just a mistake by the predecessors. Zhang Heng said with a smile, suddenly crushed the Ziyun Pill, and said: " Seniors, look at it, the Purple Cloud Pill itself is an ordinary elixir, the grade is not high, and the cultivators who need it are most likely not to be promising cultivators, because the red dust refining the heart is the most rare, and the people who have to rely on the pill to survive the heart demons are themselves a little afraid of the heart demons, so those who take the Purple Cloud Pill, if the cultivation is improved, when it comes to the tribulation, the heart demons will invade, but it will be more violent than before, because the heart demons have already broken out once, and they have not completely surrendered, and when they break out again the second time, it will not be so easy to deal with. ”

This truth is actually very simple, for example, a cultivator like Zhang Heng has a firm mind and believes that he is invincible, how can he take Ziyun Pill to verify it?

And cultivators with insufficient faith will take the Purple Cloud Pill, subdue the inner demons, exorcise the fear in their hearts, and improve their cultivation, but this kind of surrender is just an illusion, and when the real inner demons break out, they will have to suffer.

"Therefore, the elixir of the Purple Cloud Pill, in my opinion, is really superfluous, but it's a pity that cultivators rush to it and regard it as a heart refining treasure, which is really a joke. ”

"And this Taigong Ding of the predecessors, when the alchemy was made, the spirit of the instrument appeared, and he kept reciting the scriptures, but it was to make the demons more real, the more so, the more he helped to abuse, which is useless in itself, and what is the point of adding a little heat?"

The implication is that Taigong Ding is too good to refine Ziyun Dan.

Hearing this, even the machine spirit was a little speechless.

And Mu Qiankun, after a short period of thought, sighed and stood up again.

"You, come in. ”
