Lu Yu got up and walked to the medicinal herbs, took a closer look, and smiled.

Fu Danshi is a person who has high requirements for the quality of medicinal materials, usually speaking, the medicinal materials that are transported to the alchemy room, he will carefully select them, leave the ones that pass the quality test, and then pile the medicinal materials that are not up to the quality on the other side, and throw them away together when the assistant comes.

But for Lu Yu, the quality of these medicinal materials is not fatal, as long as you pay attention when dispensing medicines, it is not difficult to practice the perfect elixir.

A few minutes later, the prepared medicinal materials had been poured into the medicine furnace, and Lu Yu added firewood to light the fire, refining the elixir while practicing the humanoid teppanyaki.

It didn't take long for the Dan to become, the ordinary internal strength pill is dark red, the Dan fragrance is very strong, the medicinal power escapes quickly, it will be slightly hot in the hand, after swallowing it in the abdomen, there will be some impurities mixed in the medicinal power, hindering the absorption of the medicinal power, although these impurities will not cause the pill to stop, but it will multiply the time and difficulty of the pill taker to transform the internal strength, Lu Yu's goal, of course, is not an ordinary internal strength pill.

Lu Yu opened the medicine furnace, only to see the red and shiny pills, evenly distributed in the furnace, Lu Yu picked up a pill, carefully observed, the basic internal strength pill that he had practiced was bigger than the perfect Bigu Dan, and he started with a slight sink, and he couldn't smell a trace of the danxiang under his nose.

Lu Yu shook it hard, the pill shattered, the rich aroma suddenly exploded, inhaled into the body, suddenly felt uncomfortable, every cell seemed to be activated, greedily competing for every trace of medicinal power, a warm current flowed into the body along the hand holding the broken pill, a gas evenly covered the skin, turned into energy, and in Lu Yu's opinion, this energy is the internal strength without attributes, and it needs to be run to transform it, but this process is faster than simple cultivation, I don't know how many times.

Lu Yu nodded with satisfaction, his basic internal strength pill was indeed perfect.

He put away the more than 500 pills in the furnace, put them back in his room, and after thinking slightly, he put a bottle of internal strength pills containing 50 pills on the table commonly used by Fu Danshi, although Fu Danshi has a good face, but his nature is not bad, since he saved himself, and let himself get such a useful stunt, what harm is it to himself?

Besides, the higher Fu Danshi's status, the more likely he is to come into contact with the high-level Danfang, once he gets it, isn't it also equivalent to getting the upgraded version of the Danfang?

Then, Lu Yu sat in front of the fire and ran the humanoid teppanyaki, the heat and medicine were combined rapidly, and in just a few breaths, the proficiency of the humanoid teppanyaki reached 5/100.

Sure enough, it was much faster, Lu Yu's eyes were full of smiles, as long as he could train the humanoid iron plate to perfection, his true combat power should not be inferior to the peak of the second layer of strong skin.

Then, he devoted himself to cultivation, as long as the medicinal power was slightly weak, he would swallow a basic internal strength pill, and the proficiency of the humanoid teppanyaki was also growing rapidly, such a cultivation method, even if a disciple-level person saw it, he would vomit blood with jealousy.

After a few hours, the proficiency of the humanoid teppanyaki reached 11/100.

But Lu Yu, who was supposed to be happy, his expression became heavy, and he found that although the medicinal power in his body was enough, he could no longer feel the heat around him.

This is a problem with the structure of the medicine furnace, in order to preserve the heat as much as possible and prevent the fire controller from being burned, the material and structure of the medicine furnace can prevent the escape of energy to the greatest extent, and Lu Yu, who is outside the medicine furnace, naturally cannot use this to convert too much internal strength.

Therefore, for the current Lu Yu, if he wants to practice internal strength at the fastest speed, there are two choices in front of Lu Yu, first, get into the medicine furnace and enjoy the same heat supply as the medicinal herbs. Second, get into the furnace and experience the fiery service without dead ends.

Thinking about the ending of the two ways, Lu Yu shuddered.

"It seems that I have to find a suitable way?" Lu Yu frowned and thought for a while, and suddenly thought of something, "I have to get myself a house first." ”

It was still early, so Lu Yu used the medicinal materials of bad quality to refine a few furnaces of the Basic Internal Jin Pill and sent them back to his room, and then, as long as he gave Master Fu Dan another lesson, he could devote himself wholeheartedly to cultivation.

When the morning came, Fu Danshi walked to the alchemy room excitedly, and it was not until the door that he calmed down and pretended to be light and breezy in Izumo, this night, he didn't fall asleep at all, of course, this is not to blame him, no matter who it is, the ability that has not improved for decades has suddenly improved a lot, and it is not easy to fall asleep.

But he knew that this was just the beginning, as long as Lu Yu was there, his alchemy skills would become stronger and stronger, and he had even thought about what to say after he proved to his brothers that he was the strongest one.

He walked into the Dan room and saw Lu Yu sitting in front of the furnace with his eyes closed, and couldn't help but sigh with emotion, he was a demon himself, and he was so diligent, how could others live?

He didn't bother Lu Yu, walked straight to the dispensing table, and suddenly found a bottle on the table.

"This is ......" Fu Danshi glanced at Lu Yu, and then returned his attention to the bottle, he opened the bottle and poured a pill into his hand, but when he saw the red and shiny pill, Fu Danshi was stunned.

"Lu, Lu Yu!" he stammered, "You refined this bottle of elixir?" His eyes widened, he breathed rapidly, and stared at Lu Yu who was gradually approaching.

"I practiced it, I couldn't sleep last night, and I saw that there were medicinal materials in the corner of the Dan room that you wanted to throw away, so I made my own opinion, refined a furnace of basic internal strength pills, and hoped that the Dan master would atone for his sins. Lu Yu bowed his head and made an apology.

"These basic internal strength pills, are you refining them at once with the medicinal materials I want to throw away?" After speaking, he glanced at his pile of medicinal materials and was stunned again.

"Yes. Lu Yu replied respectfully, waking up Fu Danshi who was in a daze.

"Apologize for the crime! Quickly pack your bags and follow me to see the teacher!" Saying that, Fu Danshi's iron pincer-like hand grabbed Lu Yu's arm, if such a genius was not sent to see the teacher, he would be a disciple in vain! Besides, if Lu Yu really joined the teacher because of himself, then he would be in the same faction as himself, what Lu Yu learned from the teacher, he would learn from Lu Yu, the tide rose and the boat rose, and he could be worse in the future?

"Master Dan, we have something to say!" Lu Yu was frightened by Master Fu Dan's sudden performance.

"What Dan Master, call me Senior Brother!" Fu Danshi's eyes were red, and he pulled hard, which also made Lu Yu fully feel how weak a little guy with a strong skin level was in front of a strong man at the bone forging level, and he was very sure that once he went out of the room, he would turn into a kite under Fu Danshi's extreme speed.

"Master Fu Dan, I don't want to apprentice yet!" Lu Yu struggled weakly, he didn't want to lose his invaluable freedom because of who he was a disciple of.

"Senior brother, you just obey me!" Fu Danshi's words became more and more unpleasant. "If you stay in the Lu family any longer, you will be ruined!"

"Master Dan, please listen to me, if you insist after I say it, I will go with you to see your teacher. Lu Yu yelled.

After hearing the roar, Fu Danshi, who was slightly hesitant, still let go of Lu Yu, and when it came to this, he didn't listen to it, and he couldn't say it, but in his heart, he didn't believe that Lu Yu could convince himself.

"Then I'll say it. Lu Yu replaced himself with a last convincing voice.
