Liu Mu spent most of the day alone in the oil mill, and saw bottles of oil on the shelves, and then posted labels, and several people were in charge of recording them.

Specialized.

Yanagi loved to see such scenes.

Although it is not as good as the feeling of the laboratory in later generations, it is just to choose different raw materials and then use the simplest and most primitive pressing, but this attitude and concentration move Liu Mu.

Leaving this oil mill that only squeezed oil but never sold a drop of oil, Liu Mu came to a place with beautiful mountains and rivers, where there was a Taoist temple in the middle of the mountain.

If the green forest master comes here, he will definitely find that there are a lot of secret sentinels around here, these secret sentinels are monitoring everyone who approaches this temple, for those who are really skilled, these are not called secret sentinels, they belong to the defense personnel who deliberately let them know, and the real secret sentinels should be in a more private place.

Since Liu Mu chose Cixi, he didn't even build his own garden, but he built such a Taoist temple.

This Taoist temple is also a true Taoist temple, enshrined in the word heaven and earth, there are five big characters at the door of the town Yuan Wuzhuang view, and the Taoist priests in the are all true Taoists, the main Taoist number is Zhen Yuanzi, and each view is called Zhen Yuanzi.

When Liu Mu walked into the Taoist temple, he put the troll he carried on the shelf in front of the main hall, and the two guards behind him also put the horizontal knife he wore and the hidden weapon bag he carried on the shelf, and the rest of the people stayed outside, only Liu Mu entered with two guards.

Zhen Yuanzi stepped forward: "Senior brother has sent people over several times to inquire if life here is guaranteed, and senior brother has thanked him here." It's just that the food sent here is too good, and Daomen Qingxiu shouldn't care too much about material desires, can the junior brother order it to be halved. ”

Liu Mu was a little ashamed after hearing this, because these were not arranged by him, and should have been personally inquired by Dugu Lanruo.

Liu Mu replied: "Senior brothers and nephews work hard day and night, the food is just a little bit of my heart, since the senior brother said, then everything depends on the senior brother, every five days someone will send all kinds of needs, and then the senior brother will set a list of five days." ”

"That's the best."

This is the top experiment of the Dao Gate of Yanagi, and there is no one.

Liu Mu's learning is not good, and what can really be done with chemistry knowledge is the junior high school level and a little bit of chemistry knowledge in the first year of high school.

In the final analysis, there are only three words that this Taoist view willow wood provides.

Acids, alkalis, salts.

With these three words, at present, Daomen Zhenyuanguan has relied on his own study and research to compile the theory of rust of iron and bronze, and the anti-rust alloy of steel products.

Chemical tests of the most common elements such as carbon, oxygen, and hydrogen.

The extraction of oxygen was achieved two years ago, and after moving to Cixi, the use of alkali in the laboratory has reached a new level, and it is no longer crude caustic soda to treat raw silk, but only more than fifteen kinds of alkali for raw silk.

Perhaps these are placed in the modern era of later generations, and a college entrance examination student in science can understand it.

But for Datang, all this is subversive knowledge.

Zhen Yuanzi accompanied Liu Mu inside, but Liu Mu did not enter any courtyard, but only watched from a distance outside.

Zhen Yuanzi said to Liu Mu: "There has been a breakthrough in the research of nitrogen, phosphorus, and potassium. It is estimated that you can try to make ore fertilizer this year, and you will know the effect after picking a piece of land next spring. ”

"This is very important, the saint is very concerned about the use of efficient fertilizers. The grain yield per mu is more than 1,000 catties, which is a goal that the sage hopes to achieve in the next five years, the most important of which is ore fertilizer. ”

"Yes, a few people have been arranged here to study the analysis of ores, there are spirits in heaven and earth, different mountains and different waters are very different, where is the difference, it seems that we have first glimpsed the way, this is the avenue. Compared with the alchemy path, this is the avenue for the benefit of the common people. ”

"Senior brother has a point."

Zhenyuanguan, most of the top Danshi of Taoism are here, and there are more than 1,000 disciples alone, they are the chemists of Datang, and they have opened the door of Datang's chemistry with the simplest words of acid, alkali and salt in Liumu.

Yanagi can't help academically, and all he can do is give a lot of money.

That night, Liu Mu spent the night in Zhenyuanguan, and dinner was also eaten in Zhenyuanguan.

Judging from the dinner, Zhen Yuanzi is a very frugal person, and his behavior is really the word Qing Xiu.

Yanagi looked at one of the pots of soup in a daze.

It was a beautiful soup with snow-white tofu, green spinach, and a few tender bamboo shoots.

"Senior brother, what's wrong with this soup?"

Liu Mu came back to his senses: "Senior brother, do you remember that there is a fruit called prickly pear in Lingnan, and this fruit is equivalent to arsenic with shrimp?" ”

"Remember, Zhenyuanguan also has research on this. It didn't matter what you said before, but now the senior brothers, junior brothers, and nephews of Zhenyuanguan also understand that this is a reaction of some kind of substance. ”

Zhen Yuanzi's words are already quite professional.

"Senior brother, eating tofu and spinach together will affect the absorption of calcium, calcium is the most important substance in the composition of human bones, and if it affects absorption, it will cause hypochondriasis. Tofu and bamboo shoots are eaten together, and in the long run, they will be drenched. ”

"Ahh Zhen Yuanzi was taken aback.

Liu Mu was very indifferent: "It's okay to eat it once in a while, and it's not a big deal to eat it ten times." It's not just that you don't eat food, you just remind your brother. ”

"Yes, yes!" Zhen Yuanzi said two words in a row.

Zhen Yuanzi can also understand this matter, in the past, some poor Taoist temples were difficult to even eat, and there was a reason to care about what kind of food was born and restrained. Now that supplies are abundant, similar problems will continue to arise.

After thinking of this, Zhen Yuanzi nodded heavily: "Senior brother, the foolish brother thinks that the matter related to the people's livelihood in the world should be specially filed for study, this is a long-term research, but unfortunately I don't know how to start at the moment." ”

"Senior brother, there is no need to rush this matter, the Great Wall was not built in a day."

"The junior brother has a point."

The next day, after Liu Mu came out of Zhenyuanguan, Liu Mu spent five days to personally inspect 99 percent of the goods that Guo Xiaoke brought back from Eastern Rome this time.

Only the two hundred bought slaves Liu Mu did not see.

On the night of the fifth day, on the eve of Yoomu preparing to go to Goguryeo again, in Dugu Lanruo's room.

"Lang Jun, I watched the two hundred slaves this time, I think you should like it."

If Dugu Lan took the initiative to mention this time, it made Liu Mu a little surprised.

Seeing that Liu Mu didn't speak, Dugu Lanruo continued: "I plan to pick a few people. ”

"Nope." Yanagi refused.

"Why?"

Liu Mu smiled bitterly and shook his head: "I'm not afraid of trouble, and I don't think those slaves are not beautiful. I know where they came from, and I know her lineage. ”
