When Mu Yu went back, he didn't see the old man guarding the pavilion, but he saw that the dead wood's face was not very good, and he seemed to be sulking, and when he found Mu Yu walking in, he looked at Mu Yu's eyes almost flickering with flames.

Mu Yu asked cautiously, "Old man, your leg is not broken, is it?"

"You bastard, who told that old guy I'm back?" With Deadwood's current strength, it's just tickling Mu Yu, but in order to maintain Deadwood's self-esteem, Mu Yu thinks about it or lets him get angry.

Deadwood spoke so neatly that he must have held back his stomach. Looking at his violent appearance, he should have suffered a big loss from the old man who guarded the pavilion just now, but he can still beat people shows that the old man in the pavilion did not do anything to him, otherwise the old man with the old arms and legs of the dead wood would have been lying on the ground a long time ago.

"You didn't tell me you couldn't say it!" Mu Yu muttered.

Deadwood glared at Mu Yu, and then scolded and threw a Dan Sutra to Mu Yu. Mu Yu took a look at the cover, and it was actually "Speed Dan" that he found half-dead in the Danjing Pavilion.

"The senior of the pavilion gave it to you?" Mu Yu scolded the old guy in his heart, it turned out that he had been carrying it with him, and he lied to himself that he had lost it, so he had to look for it for a long time.

"It's still a senior! If my cultivation is still today, I won't break his leg!"

The old man's cultivation must be terrifying, and Mu Yu wanted to ask if you could really beat the old man, but in order to prevent hitting the dead wood, he still didn't mention this question with interest.

"Damn, did that old guy force you to sign a deed of sale? The deception is too much, when I have the strength, I have to sell him to the black coal kiln!" Mu Yu waved his fist, in order to relieve the dead wood, he also put out all the cruel words.

"Okay, don't pretend!" Deadwood said this, but his face softened, "He belongs to your uncle's ancestors, how can he be sold to the black coal kiln?"

"Yes, yes, yes. Misspoken. Mu Yu sneered, he just wanted to dissipate the anger of the dead wood, and he didn't know when he would reach the kind of cultivation of the old man who guarded the pavilion in the future!

"It should be sold to the Qinglou and let him be a duck!"

Deadwood's next words almost made Mu Yu plant, my God!

Mu Yu hugged the matter of returning to the original Danding furnace and talked to the dead wood, and he thought that the dead wood would scold him for not measuring his own strength, but the dead wood just sneered and said: "Even if you have a way to complete this return to the original pill, don't completely fuse, and when the vision from the sky attracts everyone, you stop, and the first one to die of anger must be the old guy." ”

Mu Yu is embarrassed, this dead wood has confidence in himself, he doesn't know how to do it yet!

Mu Yu opened the "Speed Dan", what he had to do now was to understand the real cultivation method of "Speed Dan" under the guidance of Dead Wood. According to the words of the old man who guarded the pavilion, Deadwood seemed to be the first to realize the cultivation method of "Speed Dan", but he refused to say it, as a descendant of Deadwood, he picked up a big bargain.

"Speed Dan" is an alchemy method, which comes from the comprehension of Danzu. This mental method can make the alchemist's control over various herbs extremely accurate, and it can forcibly reverse the influence of spiritual power on herbs, so that the originally mutually exclusive herbs can be fused together, so that the alchemist can complete the process of forming the pill extremely smoothly.

However, after cultivating, many disciples found that this mental method could only be effective for third-order herbs, and the mental method would change the way a person's spiritual power operated, causing this person to no longer be able to cultivate according to his original cultivation method, and then he could no longer improve his cultivation, and he could only stand still for the rest of his life, which was a very sad thing.

Many disciples of the Danding faction who had studied "Speed Dan" secretly scolded Danzu for creating a mind method and harming younger generations. It is precisely because of this "Speed Dan" that many originally talented disciples of the Danding Sect have almost become invalids.

"This 'Su Dan' seems to be very evil! Danzu didn't realize the disadvantages of this 'Su Dan'? he has harmed many genius disciples!" Mu Yu said with some regret.

"Hmph! Danzu's mental method is something that a small character like them can peep into! An alchemy mentality like theirs that is eager for quick success and quick profit can't make a big deal at all!" He didn't feel sorry for the disciples of the Danding faction who were ruined by "Speed Dan", on the contrary, he looked down on those people very much.

In the past, many Danding factions cultivated "Speed Dan", and a large part of it was because they wanted to soar to the sky and quickly become legendary alchemists. People like them who practice "Speed Dan" in order to take shortcuts are themselves impetuous, and they have no down-to-earth heart. Impetuous and impetuous is a big taboo for alchemists, and they are destined to not go far on the road of alchemy.

Mu Yu observed that section of the Sudan Mental Method, and according to the method introduced above, he tried to pull the spiritual power in his body to run for a week, and found that this mental method was extremely difficult, and many spiritual powers operated in the opposite way of normal cultivation.

It is a very dangerous thing for spiritual power to retrograde in the body, because it will be repelled by the meridians, and if you don't pay attention, it is easy to cause damage to the meridians, and over time, it will make people's cultivation stagnate, which is the reason why many disciples who are eager for quick success and quick profit are ruined in their future.

"Qi Drawing Dantian, Retrograde Parkway, is such a dangerous mental method really created by Danzu?" Mu Yu couldn't help but ask.

Deadwood didn't speak, he seemed to be thinking about something, and it took him a while before he spoke: "This "Speed Dan" is indeed from Danzu, there is no doubt about it. But do you know what the real secret of this method is?"

The real secret?

When Mu Yu learned that Deadwood came from the Danding Sect, he was very curious about why Deadwood took such a different path? Was it just because he liked to study poisons? This excuse was never enough, how could a person who was born in the Danding Sect have been influenced by pills since he was a child, how could he find another way to take another path of cultivation? Could it really be influenced by the Sudan Mental Method?

"Why is Danzu called Danzu, do you know why?" Deadwood's tone was indignant when he said this, as if he felt aggrieved about something. For so many years, no one has ever heard his explanation, and only he knows what kind of Dan Sutra "Su Dan" is.

"Because he created the Cheng Dan system in his later years?" Mu Yu heard Cai Lie tell some of the deeds of Danzu, Danzu, as a well-known predecessor of the Danding Sect and even the entire Triple Continent, his status in the alchemy world is like the status of the true god of the Triple Continent, and he is admired by tens of thousands of people.

"That's right, he created the Cheng Dan system, and it can be said that the reason why today's pills are generally round is because of the standards he set. In the era before Danzu, the final formation of the pill was not round, but the most natural form of powder and liquid medicine, powder and liquid medicine were particularly difficult to carry, so he found another way to fuse the pill into a round solid state, and later generations found that such a pill was more convenient to carry, and the preservation was more stable, and the medicinal power was not easy to lose, so he continued his Cheng Dan system, and called him Danzu. ”

Not many people know about this past, a long time ago, medicine was medicine, either ground into powder, or directly boiled into a decoction, which is no different from ordinary Langzhong now. However, powder and decoction are not easy to carry, and Danzu refining them into pills can be described as a great change.

"But the Speed Pill Mind Method was created before he created the Cheng Dan System?" Mu Yu immediately understood this, and only in this way could he explain why the Speed Pill Heart Method could not be applied to the later alchemy path.

Deadwood nodded appreciatively, Mu Yu's brain kept spinning fast, which was what he was pleased with. He continued: "No, no, that's right, speed, speed, speed, speed, law-"

"Old man, that old man is forcing you to sign a deed of sale!" Mu Yu saw that the dead wood seemed to be deflated, and began to stutter again, he hurriedly stimulated, if he was allowed to stammer like this, he might talk about it until tomorrow.

"Damn! It's okay not to mention this matter!" Sure enough, when Deadwood thought of what he had just been coerced by the old man who guarded the pavilion, he was angry, and said angrily, "You should quickly write down this account, and you will help me get it back in the future!" ”

Mu Yu opened his mouth, he didn't know what the old man had done to him, it would make Deadwood grit his teeth with hatred. However, he suddenly felt a great responsibility, because he had to teach an old man who was stronger than the Yundan Dao people, and this was really a simple death-seeking incident.

"The Sudan Mind Method is for powders and medicinal liquids, you can usually practice this Mind Method, but you must not use it in the process of becoming a Dan, otherwise it will cause permanent damage to your meridians. Although this mental method is a retrograde method of qi induction, it does not conflict with your usual cultivation methods, and will even make your cultivation speed faster, and there are no side effects. The reason why they are listed as chicken rib heart method by the disciples of the sect is because their cultivation of this heart method is used in the process of becoming a Dan without exception. Deadwood sneered.

"Then why didn't you tell them about it?" asked Ki Yu.

"Hmph, I have cultivated this mental method, and since then I have never refined a formed elixir, only the most precious powder and liquid, but they don't agree with this elixir, so they don't believe what I say. Deadwood pursed his lips.

No wonder the dead wood's medicine is bottled and canned, and the last time he was robbed by Mu Yu, Mu Yu also complained that these bottles and cans were really troublesome to use. Deadwood cultivated this mental method and embarked on a different path, taking a Dan path that was abandoned, a Dan path that was not recognized by the current cultivation realm, and Mu Yu could feel the sadness of Deadwood walking alone on this road and not being understood.

"In fact, in ancient times, Dan Dao was not called Dan Dao, but Medicine Dao. "Speed Dan" was not originally called "Speed Dan", but "Speed Medicine". The Medicine Dao is actually better than the current Dan Dao, just like Lang Zhong, who is now looked down upon. The current Dan Dao is more used in cultivation, while the Medicine Dao is used in saving people and curing diseases, but the study of the Medicine Dao is often based on the body to test the medicine, so it is inevitable that you will be poisoned. ”

Deadwood's words solved a lot of Mu Yu's doubts, just like why Deadwood went to save people, why was he poisoned like that, his "Poison Sutra" should be a by-product of the study of medicine, as for why it is called "Poison Sutra" instead of "Medicine Sutra", this is purely Deadwood's personal preference. The outside world gave the dead wood the title of poisoner, and he took advantage of the situation to name it so.

"Then what is the purpose of you asking me to find the 'Speed Pill'? The Speed Pill Mind Method can't be used in alchemy at all, and if I want to get a quota, I have to defeat them in alchemy!" Mu Yu asked puzzled.

"Do you think that after so many years of studying the medicine path, I still can't find a way to transform the medicine path and the pill into each other?"

"Can you make the Speed Pill Mind Method also apply to Cheng Dan without being affected?" Mu Yu was surprised.
