"After a while, I will refine another furnace of Bigu Dan, but I will deliberately expose some flaws in the process, and what you have to do is to find these flaws and correct them one by one. Fu Danshi's eyes were a little evasive, it was obvious that he was copying Lu Yu's Bigu Dan many times, and he couldn't pull his face to ask Lu Yu directly, so he thought of this kind of excuse.

"Please also ask Danshi's subordinates to be merciful. Lu Yu, who had guessed Fu Danshi's little idea, did not expose it, since Fu Danshi wanted to learn, he would teach him.

So, Lu Yu put on a pleasant voice and euphemistically pointed out a flaw in Fu Danshi's alchemy process, and in the whole process, Fu Danshi fell into shock more than once, Lu Yu sometimes said exactly the same thing as his teacher, but Lu Yu was more patient and said in more detail, which made Fu Danshi feel like the clouds were clear.

"I see, in the past, I paid too much attention to the form of alchemy, and forgot the essence of alchemy. After finding the problem, Fu Danshi sighed, "This Lu Yu is really a demon." He smiled bitterly, there was a reason for him to develop a rigid alchemy habit.

Generally speaking, it is difficult for people who are new to alchemy to start from the essence of alchemy and successfully dispense medicine, so for them, the best way is to choose the best materials and use mature dispensing techniques.

And the pill refined by this method, although it can't have perfect quality, but at least it won't become a waste pill, even the teacher who is called an alchemy genius, at the beginning, is just in the stereotypical alchemy again and again, gradually mastering the essence of dispensing.

And this kid in front of him, not only chose to start from the essence for the first time, but also practiced the perfect Bigu Dan, if this is spread, it is estimated that those Dan masters who can only look up to their own teachers will come here one by one to fight for a bloody flow.

With the help of Lu Yu, Fu Danshi's Bigu Dan furnace is better than the other, and in the end, although it can't reach the level of perfection of Lu Yu's furnace, it can also be perfect from time to time, Fu Danshi sighed, he knows that he has mastered everything he can master, and the reason why he is not as good as Lu Yu is because of his talent, he can only let himself stop here.

But after thinking about it, he was very happy, Lu Yu's guidance not only helped him improve the refining method of Bigu Dan, but also made him discover that he still had hope of breaking through, if he continued like this, I am afraid that it would not be long before he could refine the innate pill and take a step further on the path of the Dan Master, thinking of this, his eyes were much hotter when he looked at Lu Yu.

"Danshi, is there anything else?" Lu Yu was uncomfortable.

"No, you can go and rest today. "There were too many harvests on this day, and Fu Danshi had to find time to digest and digest them.

After Lu Yu said hello, he left the alchemy room, and as soon as he came out, he took out the Bigu Pill in the bottle and swallowed one.

Gain 20 energy and have 110/1000 energy.

"The Bigu Dan I refined is really extraordinary. Lu Yu nodded with satisfaction, then grabbed a handful and poured it into his mouth, as soon as the Dan entered his stomach, he was directly decomposed into energy by the system, and after a while, the energy was full.

Suddenly, Lu Yu broke out in a cold sweat, and after the energy was fully recovered, he accidentally swallowed five or six grains, but he didn't expect the damn system to not help this time, which made Lu Yu understand for the first time what it was like to be full, or about to burst.

"No, I have to learn something quickly!" Feeling as if something terrible was brewing in his belly, Lu Yu rushed to the door in one breath, as soon as he went out, Lu Yu secretly screamed that it was not good, it was already afternoon when he returned to Danyuan with Fu Danshi, such a toss, it was already the middle of the night, Wuding Courtyard was different from Zading Courtyard, the residence has always been a single room, and he can't break into a man's bedroom in the middle of the night, right?

Just when Lu Yu was thinking wildly, the breath in his belly became more and more intense, and if he continued like this, he would probably bloom like a festival fireworks, of course, nine times out of ten, it would be like fireworks, and it would never return to its original state.

Well, I can't even think of someone else's bedroom now.

"That's right, Master Fu Dan!" Lu Yu suddenly remembered something, ran into the alchemy room in one breath, and saw Master Fu Dan who was staring at him, his heart was overjoyed, and he hurriedly read the skill.

Basic Internal Strength Pill Refining Method: It can refine an elixir that can give birth to a small amount of internal strength, which is suitable for the stage of strengthening the skin. Requires 50 energy.

Lu Yu hurriedly chose yes, and as soon as he made his choice, he suddenly felt that his abdomen had calmed down a lot, but this was far from enough.

It can be upgraded to the perfect basic internal strength pill refining method, the elixir is more powerful but milder, and there are no impurities, compared with the ordinary internal strength pill, it can double the speed of internal strength cultivation in the strong skin stage, and it requires 50 points of energy, do you want to learn?

After making the choice, the energy was full again, but unlike just now, his satiety was already acceptable, and the current energy was 1100/1100.

"The next time I eat Bigu Dan, I will definitely eat it by the grain. Lu Yu, who was afraid, wiped the sweat from his forehead.

"Lu Yu, why don't you go to rest yet?" After hearing the voice, Fu Danshi opened his eyes.

"I have just seen the refining method of Neijin Pill, and my heart is itching, so I have come to ask you for advice. Of course, Lu Yu can't say that he is full, so he quickly found a suitable excuse?

"Neijin Dan?" Fu Danshi's eyes suddenly opened, and his heart was full of horror, "Could it be that he has already mastered the refining method of Neijin Dan?" Impossible, it took me two years from learning to refining the first barely usable Neijin Dan refining method, even when the teacher studied, it took three months, the teacher has surpassed the innate Dan master, if Lu Yu really learns it in less than an hour, where will he go in the future?"

Thinking of this, Fu Danshi was a little afraid to think about it, he shook his head and waved away his distracting thoughts.

"Lu Yu, the road of alchemy should not be rushed, you have a good rest tonight, and wait until tomorrow morning, I will show you the refining method of the Inner Jin Pill, what do you think?" Fu Danshi didn't realize that he was speaking to a strong layer of martial arts in an inquiring tone.

Of course, he said this selfishly, if Lu Yu really mastered the ability to refine the internal strength pill, and tonight he was already lacking in energy due to digesting a lot of knowledge, and what he learned again would be greatly reduced, rather than this, it is better to wait until tomorrow, nourish his spirit, and learn more new things.

"What Danshi said is, then I will retire first. ”

After perfunctory Danshi, Lu Yu returned to his bedroom, recalling today's encounter, and sighed deeply, "I'm still too weak." "If Fu Danshi hadn't arrived in time, most of the current Lu Yu would have been a wasted person, as soon as he thought of this, he knew that he had to become stronger as soon as possible, at the very least, the reason for making the enemy jealous had changed from Lu Yu's backer to Lu Yu himself.

In this way, he decided to cultivate his internal strength quickly.

After sleeping for two hours, Lu Yu, who was full of energy, hurriedly walked to the alchemy room, and saw that Fu Danshi had left, Lu Yu breathed a sigh of relief, he lit a fire and burned firewood, and ran a humanoid teppanyaki in a suitable position, but after a long time, his proficiency did not increase much, which made Lu Yu sigh dissatisfied.

"Looks like we're going to have to think of something else. Thinking so, his gaze fell on the pile of medicinal herbs in the corner of the alchemy room.
