Mao Chongwu, a little person in the fairy courtyard, will naturally not be taken seriously by Rui Shimi. In the eyes of ordinary people, judging the quality of the Danshi is not much different from choosing ginseng, first of all, it is to look at the vintage, the older the more precious. Hu Wenshu, as a formal Dan Master, has been immersed in the alchemy room for many years, and in Rui Shimi's heart, he is a thick hundred-year-old ginseng. Mao Zhongwu is just a small outer disciple who serves as a deacon, and in comparison, it is simply a small young ginseng that has just been planted in the back garden for two years, and at most it is the thickness of a little finger.

Rui Shimi felt that He Yun'er was either really poor and sour, and she couldn't afford to hire a clever Dan master to teach Guiyuan Danshu, or she was cheating on her heart, if Gui Yuan only practiced the pill to be examined, then she would invite a deacon disciple from the outer door to go over. Compared to the two, it is clear that the latter seems to be much more likely.

Mao Chongwu didn't know that Rui Shimi regarded him as a little finger in her heart, otherwise she would have to shoot the case to defend her dignity. He's been so busy lately that he doesn't have time to worry about it. Gui Yuan dug out many strange utensils from that ancient book, and there were countless whimsical ideas, which always made him cry out for magic. It's just that Senior Brother Mao can't help but add thoughts in his heart, and he doesn't know how to repay Senior Sister Gui.

The Dan masters have been locked up in the Danfang for many years to focus on alchemy, and they are a relatively simple group, and they are even a little ignorant of the world. It is not an isolated case that you have to rely on the strange course of "horse folding" (immediately convincing your chat partner) to guide interpersonal communication like Gross Weight Five. But no matter how sophisticated the Dan Master is, he also knows that there are a few rules that have been passed down by the ancestors, and he must swear to abide by them from the first day he sets foot on the path of alchemy. The two most important of these are the prohibition of snooping on the alchemy skills of others, and the principle of equivalent exchange. Equivalent exchange, of course, does not mean that Danshi can only price drugs at cost when they sell them. It is more suitable for the exchange of technology and raw materials within Danshi.

Gui Yuan simply understood these two articles as copyright laws in the alchemy world. In the long run, it will indeed promote technological development and protect the best interests of the Danshi as a whole.

But Mao Zhongwu really couldn't think of how to repay Senior Sister Gui. Now that he had understood how precious and effective the alchemy tools and techniques that Gui Yuan had taught him, he had. Then you have to pay a corresponding price to exchange for the same value. Helping her refine some pills, and even indiscriminately modifying some pills is just a gesture, if this is a reward, he can't pass his own level, and sooner or later he will have to form a demon.

The book says that when there is nothing to repay, there is only a promise with one's body. Senior Brother Mao couldn't help but fall into a deep melancholy, and he didn't know if Senior Sister would allow him to eat a bowl of rice balls occasionally in the future.

After hesitating for a long time, Mao Chongwu hadn't decided whether to tell Senior Sister Gui or not, but Gui Yuan took the initiative to come to him, claiming to promote these alchemy secrets and utensils in the alchemy room. Senior Brother Mao's eyes suddenly darkened, and he was stunned and thought, "Is Senior Sister Gui going to open a harem?"

How attractive is the magical alchemy method of longan, the gross weight five already knows a lot. Pushing himself and others, he really didn't think that the brothers and sisters of Danfang could refuse such a big temptation. He thought desolately, he was afraid that many of the immortal masters in the Danfang would nod their heads in agreement, and when the time came, the Gui Mansion would be in a crowd, and he didn't know if he could seize the advantage of being an advanced door.

Poor Guiyuan didn't know the twists and turns in Senior Brother Mao's stomach at all, and it was a natural idea for her to promote thermometers and precision balances. Even if there is no patent protection, she will try her best to promote the development of Dandao, after all, no one will think that the world she lives in is too advanced in medicine. In the case of such low productivity, how can she cherish the technological innovation in her own hands, which is absolutely not in line with her scientific concept of development.

Of course, since she found out that the Danshi are actually very aware of patent protection, she doesn't mind taking this opportunity to take advantage of the benefits and live a good life of eating bowls of the best pills as soon as possible.

She said to Mao Zhong a little shyly: "It's not that these tools and methods are used for free, and you always have to pay some price." I have an idea, and I would like to ask my brother to help me refer to it. ”

As soon as she said this, Mao Chongwu Yifa affirmed his harem speculation, and he held back tears and said, "Senior sister, please say that it's okay." ”

Gui Yuan muttered, "I want to set the deadline at twenty years. ”

Mao Chongwu was slightly surprised and thought, "Senior Sister Gui is so kind, is it not that she intends to occupy them for life, but that she will forget about each other in the rivers and lakes after twenty years?"

"In the past twenty years, as long as I use these tools and techniques for alchemy, I will own half of the profits. Gui Yuan explained in one breath: "You have also seen that with these things, the rate of Cheng Dan and the rate of high grade have increased significantly, but I am afraid that it will be more than two or three percent, not to mention that I only need half of the income after deducting the cost, it should not be considered greedy." ”

Gross weight five opened his mouth widely, it turned out that the junior sister hit the ground with this idea. He came back to his senses after half a salary, and felt that although this method was fresh, it was not impossible, at least he was willing to do it, and the price of this half of the profit could even be said to be quite kind, but when he thought that he didn't have to look at Senior Sister Xu Gui with his body, he couldn't help but feel a little lost.

Gui Yuan didn't know that he had just missed a luxury alchemist harem group, and he was still excited about his thoughts, "How many medicines are sold and handed over by the Dan masters, most of the alchemy rooms have records, and everyone swears by the demons in their hearts, no one should be able to repay the debt." ”

Mao Chongwu couldn't help coughing, Danshi is also dignified, is it good, who wants to rely on you for this account, don't say that it is only half profitable, even if you really want to pay for it, I am not a good man with a frown.

Gui Yuan was very relieved to see that although his senior brother's expression was strange, he was generally well accepted, "I still have some additional conditions. These Dan masters will promise to guide me in alchemy or help me in alchemy when I need it, and of course I will also follow the principle of equivalence and give me a reward. And I want to have the right of first refusal to buy the elixir they have refined. ”

After the conditions were negotiated, Mao Chongwu began to sell the new alchemy method on a small scale, and it was quite smooth at the beginning, not at all as difficult as Gui Yuan had when he first tried to persuade him to try the Nine Heavens of Ice and Fire.

He himself felt sluggish, in fact, the Dan Masters in the alchemy room had been paying attention to him for a while. After all, the gross weight five seems to have suddenly opened up recently, and the success rate of some pills has become surprisingly high, if it is just like this, the pill masters do not take the loss of low-grade pills very seriously. However, the quality of the pills he handed in was very good, most of them could reach the top grade, and many were even of the best grades. This can't help but be amazed.

It is not difficult for experienced Great Dan masters to do this, not to mention the auxiliary alchemy spells practiced by these Dan masters, just to say that their hands are already more accurate than the best medicine scales, and the medicine they grasp can be exactly the same. Their mastery of the heat is even more wonderful, and they can always add or subtract the Dan fire in time, and open the furnace into Dan at the most appropriate time. This ensures a high rate of success and quality.

But these all need time to be honed, and the rapid change of gross weight five has greatly challenged the cognition and self-confidence of Dan masters. It's just that the pride of being a Dan Master and the Dan Dao code don't allow them to snoop on the secrets of this outer disciple.

So when Mao Chongwu privately approached a certain Dan Master to share his secrets, no one could resist the temptation, even if it all came at a cost.

And Hu Wenshu is the fourth Dan master who was asked by Mao Chongwu.
