"Swollen Grass" Fu Danshi took out the book, casually read the name of a medicinal material related to Bigu Dan, and then stared at Lu Yu quietly, waiting for him to tell the characteristics of the medicinal material.

"The swelling grass is also known as the sheep does not eat, the grass is dark brown, and the wild swelling grass grows in the ...... After eating this herb by mistake, there is a strong feeling of bloating, although it is harmless to the stomach and intestines, but the eater cannot swallow any food in the short term, which is a necessary raw material for refining Bigu Dan. ”

"Hmm. Fu Danshi's face was slightly better, Lu Yu did not repeat the words in the book word for word, but simply described it according to his own understanding, which showed that he was not rote memorizing, but understanding, but this does not prove anything, the swelling grass is the most basic plant in the book, it is estimated that he knows to refine Gu Dan, and he has mastered it first.

"Honeysuckle. Fu Danshi pronounced out a slightly more difficult name for the medicinal herb.

"Honeysuckle, named because of its silvery white body...... It can neutralize the toxicity of other medicinal materials in Bigudan. Lu Yu's answer was simple and complete, and he let Fu Danshi take a look.

"It seems that this kid is not all deceiving, but I can't just let him go, if he is deceived and loses his majesty, how will I discipline him in the future?" Thinking so, Fu Danshi made up his mind and reported the name of the medicine, and Lu Yu replied again.

Fu Danshi was a little anxious, he simply took the book and read the names of the medicines related to Bigu Dan from beginning to end, and finally, he was unwilling to even start reciting the names of other pill medicinal materials, but Lu Yu didn't even pause, and pointed out the characteristics of each medicine without any mistakes, although there was always one more sentence and one sentence less, but this just proved that he understood.

During the test, Fu Danshi's complexion changed from anger to doubt, from doubt to surprise, from surprise to shock, and from shock to joy. "Could it be that this Lu Yu is not only a master of burning wood, but also has a talent in alchemy?"

On the surface, being a Dan Master is very noble, but in fact, as a Dan Master who can only refine the acquired elixir, he is very painful, every time he goes to celebrate the teacher's birthday, the teacher will ask him, when can he refine an innate elixir for himself to see, and then look at his own brothers, some of his apprentices are stronger than himself.

But what can he do? He is by no means a person with outstanding talents, and he was able to enter the teacher's door because he spent all his savings to arrange some special entertainment activities for him when the teacher drank too much, which made the teacher reluctantly agree to him.

On the day of entry, the teacher said that as long as he could refine the elixir of the innate realm, he would be content, but he couldn't even meet the teacher's most basic expectations.

Thinking of this, he looked at Lu Yu's eyes much gentler, "Looking at your situation, the content of another book should have been learned, let's go directly to Bigu Dan, listen to my instructions to change the temperature of the fire, and." He paused, "Alchemy is not something that can be achieved overnight, learning is important, but you can't forget to rest." In his words, there was a little more concern, how did he know that Lu Yu had learned what he should have learned at a glance, in his heart, Lu Yu must have studied hard all night.

"I'm going to dispense medicine now, don't be busy burning firewood yet, come and have a look. "Normally, in order to improve the efficiency of alchemy, Fu Danshi will let the helpers go directly to burn firewood, and don't give them the opportunity to dispense medicine at all, but Lu Yu is different, in his eyes, Lu Yu is diligent, talented, what is like anything, if he is properly cultivated, he may be able to refine those simple pills for himself, and he will have time to impact the innate pills.

When Lu Yu heard this, he honestly stood beside Fu Danshi, although he had surpassed Fu Danshi in the refining of Bigu Dan, but after all, he had to rely on others to eat.

Fu Danshi carefully observed the quality of the medicinal materials to determine the amount of medicinal materials, while Lu Yu on the side frowned.

"It seems that this kid is thinking, well, yes, most people will only look at me when they dispense medicine. Thinking of this, he showed a smile, "Don't worry, you have just come into contact with these medicinal materials today, and after a long time, you will naturally understand." The implication is that he has decided to accept Lu Yu as a disciple.

"Yes. Lu Yu nodded yes, but kept muttering in his heart, "Big brother, you have been refining the pill for so many years, how can you mix a Bigu Dan with several flaws? This furnace pill is not to mention perfect, it is good to be able to reach the top grade!"

"The medicine is ready, you go burn wood. After a while, Fu Danshi looked at the prepared medicine and nodded with satisfaction, "I'm in a good mood, and the medicine is also good." ”

Lu Yu ignored him and ignited the fire, and the heat of the flame increased rapidly, and soon it reached the most suitable temperature at the beginning of Bigu Dan.

"This fire is burning well. Fu Danshi nodded, and was just about to ask Lu Yu to maintain this heat, but suddenly found that the heat had stabilized. Gao glanced at Lu Yu again, remembering that when the brothers and sisters first started, they were all stunned, and they had to strictly abide by the orders of the alchemists at every step, that's it, and it was very likely to refine inferior pills, it seems that Lu Yu has studied the practice of Bigu Dan almost completely.

After the whole process of medicine, closing the furnace, refining medicine, and taking pills, Fu Danshi suddenly found that he had not even given an order, and the whole process was smoother and natural than refining medicine by himself.

As soon as the lid of the furnace was opened, the danxiang was fragrant, Fu Danshi put hundreds of pills into the utensils, observed them every grain, and then laughed heartily, "Round and full, the danxiang is pleasant, a grain can be worth a day, a good pill that has not been seen for a long time!"

"How do you know how to adjust the flame?" Fu Danshi asked curiously.

"Dan incense in the furnace. Lu Yu replied honestly, in fact, the Dan Master before the innate could not see the situation in the furnace, and he could only grasp the progress with the Dan incense.

"Good boy! You can judge it just by reading a book? Thinking so, Master Fu Dan took out a bottle, put thirty pills of Bigu Dan into the bottle, and handed it to Lu Yu.

"Take it. Fu Danshi handed the bottle to Lu Yu's hand, "This is what you deserve." "Normally, every time the furnace is opened, it is good for Master Fu Danshi to reward his assistant with one or two grains, but this time, he rewarded thirty grains.

"Xie Danshi!" Lu Yu took the bottle and quickly swallowed a pill, as he expected, the pill was systematically decomposed into energy as soon as it entered the body.

Gain 10 energy, existing energy, 90/1000.

"Why did you eat it?" Fu Danshi's tone was slightly reproachful, "Bigu Dan is not a sugar ball, ordinary martial artists are willing to use it only after retreat or going to dangerous places." ”

"Master Dan, I just want to try the feeling of eating high-quality Bigu Dan. Lu Yu used a beautiful voice.

"Why?" Lu Yu's voice skills and the word "high-quality" made him feel better.

"Because I want to use this as a standard and try to make a furnace. Lu Yu said respectfully, in fact, he just wanted to get more backup energy.

"What, you want alchemy?!" Fu Danshi's voice suddenly raised, this kid who had only been in contact with alchemy for a day, actually wanted to do alchemy? He wouldn't be underestimating alchemy, would he, let him learn a lesson, "Okay, let's refin, but let's talk about the ugly things ahead, if the Dan refining is abolished, I will use your twenty-nine Bigu Dan to compensate me for my materials, do you dare?"

"Then thank Danshi for the opportunity. Lu Yu saluted and walked to the side of the medicinal herbs.
