After selecting the medicinal materials, the woman took out the token again and passed through the prohibition, making Han Yu's eyes light up slightly, and asked.

"Senior sister, how did you get this token, so that you can walk through this place at will?"

The woman chuckled twice and said angrily:

"This thing can only be obtained by becoming a Dan Master, and you are good at studying, and the medicine boy is not without the opportunity to become a Dan Master......

When she came to the attic, the woman carefully placed the medicinal herbs she had taken on top of a rolling cloth, and then she spoke:

"Master, each of the seventy-two medicinal materials used to refine the Qingshuang Pill has been taken here. ”

Elder Shi, who was sitting in front of the Dan furnace, snorted and instructed:

"Open the attic guardian formation, medicine boy, remember not to disturb me when I refine the pill later, you have to keep in mind Xue'er's movements, and you may have to come to help the pill next time." ”

After Elder Shi finished speaking, he suddenly waved lightly, and a cyan flame emerged and fell into the bottom of the Dan furnace, about dozens of breaths, a green smoke suddenly emitted from the Dan furnace, and the moment he saw this green smoke, Elder Shi immediately opened his mouth and shouted.

"Three drops of white mango green juice, crushed purple cloud leaves. ”

With Elder Shi's words, the woman on the side quickly took a small white fruit and held it in her hand, squeezed it and dropped three drops of cyan juice and floated it to Elder Shi, and then took a purple leaf again, crushed it in the rapid rubbing of her hands, and then floated to Elder Shi again.

Every time the woman sent a medicinal material, Elder Shi would quickly throw it into the Dan furnace, and his mouth was still constantly opening, and with every time Elder Shi spoke, the woman next to him would quickly take a medicinal herb and treat it, and then send it to Elder Shi.

Han Yu on the side was dazzled, although he had tried alchemy when he was in the Heavenly Scar Sect, what he could refine was the most basic first-grade pill, but at this moment, the pill refined by Elder Shi was obviously much more advanced, and his movements were suddenly countless times more cumbersome.

But just as Han Yu was looking at it with relish, the Dan furnace suddenly slammed and exploded, and the sudden scene frightened Han Yu into a spirit, and when he looked up, he saw that Elder Shi's face was stained with a black object at some point, and there was a faint fragrance of medicinal herbs on it......

Elder Shi, who was sitting in front of the Dan furnace, was stunned and maintained the posture of throwing in the medicinal herbs, and muttered unconsciously in his mouth.

"Why did you blow up the furnace, why did you blow up the furnace, could it be that the old man did something wrong?"

While Elder Shi was muttering to himself, Han Yu's mind was filled with the voice of the old man's disdain.

"I only know how to grasp the time when the medicinal materials are thrown in, but I don't adjust the fire, if this method is to refine ordinary pills, you can refine the Qingshuang Pill at the peak of the four grades, if you don't blow up the furnace, the old man will eat the Dan furnace raw......"

The words of the old man made Han Yu slightly stunned, and he couldn't help but ask in his heart:

"Old man, do you still know this?"

Hearing Han Yu's name, the voice of the old man in his mind trembled obviously.

"Boy, if you dare to call me old man again, the old man will devour you even if he dies together!"

Han Yu immediately laughed dryly twice and spoke cautiously.

"Before... Guy, do you know this?"

Seeing that Han Yu changed his words, the old man snorted coldly, and a light hum that deliberately lengthened his tone came out, which made Han Yu roll his eyes for a while.

After that, Elder Shi tried alchemy a few more times, but all of them ended in a fryer, so he had no choice but to dismiss Han Yu and the others and go elsewhere to ask for advice on his own.

Leaving the attic, the woman was also full of doubts to move forward, Han Yu saw that there was nothing to do, so he followed the woman's side, wanting to mention something, but he didn't know what excuse to tell.

Unconsciously, the two of them came to a high platform, on which an old man in white sat upright, and below, there were nearly a thousand disciples, all of whom sat on the ground, quietly listening to the words of the old man on the stage.

"The Dan Dao is unpredictable, and all the details of the alchemy have the potential to change the quality of the pill.

The refining of medicinal materials, the control of flames, or the time invested, the slightest difference, the elixir refined may make a world of difference, this is the Dan Path.

There are thousands of people present, and there are very few people who are Dan masters, which is an incomprehension of Dan Tu. The old man will continue to preach here tomorrow and share with you the changes in the Dan Path and the confusion of medicinal materials!"

Just as the old man finished his sermon and was about to leave, the woman beside Hanyu spoke.

"Chen Xue, a junior, has something to understand, and I hope that my seniors will solve my doubts. ”

Hearing Chen Xue's words, the old man who was about to leave turned around and looked over.

"Let the old man solve his doubts, there needs to be something to exchange!"

Chen Xue nodded, took out a light cyan fruit and held it in his hand.

"This is the top-grade spiritual fruit Fan Qingguo, which can be used as a medicine for the four pills, and the doubts of the younger generations are the refining of the Qingshuang Pill!"

When the old man said that there was a need to exchange something in exchange, Han Yu's eyes suddenly flashed with a strange light, and he faintly felt that he seemed to have discovered a way to make money, and the old man in his mind faintly felt that something was wrong, but he didn't know what happened.

After listening to Chen Xue's story, the old man on the high platform was silent for a moment, and was about to open his mouth to answer, but Hanyu on the side gave the answer first.

"The refining of the Qingshuang Pill focuses on controlling the flames, and the elders' attention is all on the grasp of time when refining the pill, but they ignore the control of the flames, which is the key to the fryer!"

Hanyu's opening made Chen Xue stunned, but the old man on the high platform snorted coldly.

"The junior's opinion is not bad, can you dare to gamble with the old man on the identification of medicinal materials?"

The old man opened his mouth like this, which was tantamount to admitting the truth of what Han Yu said, and Chen Xue on the side was stunned for a moment again, not wanting that Han Yu already had such a deep insight into Dan Dao, and he was still teaching the other party to identify medicinal materials earlier......

Hearing what the old man said, Han Yu's eyes suddenly lit up, but he quietly negotiated with the old man in his mind.

"Senior, if you don't help me, I will try to urge the Seven Realms Flower to force you out, if you can't succeed, I'll suffer some backlash, but if you succeed, ......"

The old man's face changed, and he suddenly felt like he was gritting his teeth, what Han Yu was most afraid of in his body was the Seven Realms Flower, if Han Yu really urged the Seven Realms Flower to drive him away, even if he couldn't force himself out, it was difficult to guarantee that he would not suppress himself again, and then he was afraid that he would have to fall into a deep sleep again.

Gritted his teeth, he suddenly spoke with hatred.

"I'm going to bet about seventy percent. ”

Hanyu sneered twice.

"Give you thirty percent, if you don't help, then don't talk about it!"

When Han Yu and the old man were arguing, the old man on the high platform couldn't bear it anymore, and suddenly two sneers came out.

"Isn't the junior scared? If he is afraid, it doesn't matter, but he will appear in the old man's preaching place again in the future. ”

Han Yu smiled slightly and didn't answer, and suddenly launched seven steps under his feet, and when his figure stopped, he had already appeared on the high platform.

"How do seniors want to gamble, and why do you bet?"

The old man in white had an ugly face, and what the person who opened the sermon was most afraid of was that someone would tear down the stage, which was a robbery, not only the person who listened to the sermon, but also the fame on which he depended.

Although the old man at this moment was annoyed, he didn't care too much, the person in front of him was too young, and he didn't have much success if he wanted to come to Dandao, so he suddenly opened his mouth when he had this idea.

"The old man will compete with you to identify medicinal materials, and the people in the audience will take out a kind of medicinal materials, and you and I will take turns to answer, if one party can't answer, or answer incorrectly, the party who can correct it wins. As for the gambling contract, the old man has ten fourth-grade medicinal herbs, plus the three thousand Dan stones that the old man obtained when he preached, this stone can be exchanged for real high-grade medicinal materials in the herb garden, do you dare to bet?"

The acquisition of Dan Shi is quite difficult, if you are a medicine child, you only have a fixed number of 100 pieces per year, while Dan Master or his disciples can obtain them by performing the tasks of the sect, but the number of them is only 1,000 pieces per year. The only fastest way to earn Dan Stones is to preach, attracting countless medicine children who aspire to become Dan Masters to listen and collect Dan Stones. However, preaching requires profound attainments in the Dan Dao, and not everyone can try it.

When Hanyu heard about the gambling contract, his eyes suddenly lit up, but there seemed to be nothing on his body that could be used as a gambling contract, but it was inconvenient to take out the magic weapon, and after thinking about it, he wanted to take out a ball of Hongmeng Spirit as a gambling contract, but he was scolded by the old man, on the grounds that this thing was too precious, and if he took it out, he was afraid that it would inevitably cause some unnecessary trouble.

In the end, under the selection of the old man, Hanyu took out three of the small black fruits obtained from the white fox.

I don't know what this fruit cold jade is, but the old man said that three pieces were enough, but the old man on the other side stared at each other and spoke angrily.

"There is no aura emitted from this fruit, and even the aura of plants and trees is scarce, so usually you take out a bet with me, is it not to play the old man?"

Listening to the old man's words, Han Yu was embarrassed, but then his eyes widened, and he continued to play with it.

"Seniors don't know this fruit?"

The old man was stunned, and he vaguely felt a trace of something bad in his heart, he just exported to compete with the other party for the identification of medicinal materials, if this thing is a mortal fruit, but if it really belongs to medicinal materials, wouldn't he have lost before he competed?

In such a scene, many people in the audience who listened to the sermon also saw the heresy, and immediately looked at Han Yu, waiting for the following, even Chen Xue, who was slightly stunned in the distance, also found a place to sit in the front and looked at the two people on the stage.
