What the Taoist priest wanted to offer to Li Buqi was sulfuric acid!

With sulfuric acid, hydrochloric acid, nitric acid, and dyes can be made. It is not an exaggeration to say that sulfuric acid opened the door to the chemical industry, and such an important thing Li Buqi thought that he would make it himself after a while, but he didn't expect that it would appear so quietly as a by-product of Taoist alchemy.

Li Buqi was also full of emotion at the half bottle of black liquid!

Li Buqi put away his thoughts of wanting to assassinate Lao Dao, and carefully asked Lao Dao how this sulfuric acid was made. Lao Dao took out a black book, turned it page by page, and explained to Li Buqi how much pyrite was used as gold for alchemy, how much lead was used, and sometimes mercury, dansha and other miscellaneous things were added.

This is a special experiment log! This was the first Taoist priest Li Buqi saw in the Great Song Dynasty who carefully recorded the experiment, so he boasted: "Immortal Chief, I remember this note well. ”

Unexpectedly, Lao Dao said: "This is still because of Li Daguan." ”

"Oh? What does it have to do with me? Li Buqi wondered.

Lao Dao said flatteringly: "A few years ago, my junior brother traveled to Tokyo, and heard that Li Daguan was famous, and I heard that Li Daguan was teaching the Fa at Qingyuan Academy, so I went to listen. After he went back, he told Poor Dao, and Poor Dao began to take notes every time he made alchemy. ”

This is unintentional. Since Lao Dao can help spread the method of keeping experimental records, Li Buqi can't be too stingy, and gives Lao Dao 3,000 yuan, so that Lao Dao can't find the north, and immediately goes to the market to purchase raw materials for alchemy.

After Lao Dao was led out, Yu'er asked Li Buqi curiously: "Teacher, what is the use of this dirty water?" How is it worth 3,000? ”

Li Buqi can't say what the sulfuric acid is used for, because logically speaking, he can't know. He rolled his eyes and said, "When a baby is born, no one knows what kind of person he will become when he grows up." But if a child is gifted, there is a good chance that he will become a great student in the future. I don't know what it's used for. But according to the Taoist priest, this thing can even melt steel, and can melt many things into this water, and as far as I know, there is no other thing that can do this. It's like a gifted child, and if you study it carefully, you have a good chance of being of great use in the future. ”

After a deep sigh, Li Buqi said again: "For example, we have done experiments to plate a layer of copper or tin on the iron plate, which can make the utensils shiny and not easy to rust. However, before plating copper and tin, the rust on the surface of the iron should be washed off with vinegar, otherwise the plating will not be firm. But vinegar needs grain to make it, and grain is always in short supply. If you can use this acid instead of vinegar, then you will save a lot of food. ”

Yu'er nodded again and again and said, "Sure enough, everything in the world is useful." ”

Li Buqi smiled and asked him: "In another month or two, the Wubei Primary School will be ready, and you can go to school there." There's a lot more interesting things to learn than Yixue. When you graduate from the academy in the future, you will be a good man who can write and martial arts. ”

Yu'er asked, "Do they go too?" ”

Li Buqi said: "Wubei Primary School is a school for His Majesty to recruit the children of soldiers who died in battle, and they naturally can't go to Niu Man. ”

Seeing Yu'er's somewhat disappointed expression, Li Buqi encouraged him and said, "You will meet a lot of new friends when you go to the Martial Arts Academy, and they will treat you the same way as Niu Man." The martial arts academy is closed on six days, and you can come back to play with your classmates. ”

Hearing Li Buqi say this, Yu'er happily went to play. It seems that he is going to tell the news to Niu Man.

After the rest left, Yao just handed the newspaper in his hand to Li Buyi. What Li Buqi saw was a full-page interview, and the person interviewed was Dong Renzhang, who served as a marching senator in the army.

This interview is Dong Renzhang's grievance for Li Buqi. Previously, Qingyuan Academy's "Current Affairs News" and "Business Daily" had reported how the Liao people brutally drove the Han people to attack the city, so that the public opinion of the people was completely biased in favor of Li Buqi. This time, Dong Renzhang used his own experience to illustrate the correctness of Li Buqi from another aspect.

He said that on the way to Zhuozhou, Li Bu gave up his order, and he led a hundred cavalry to plunder the Khitan manor. When he passed by a garden and saw that it was the property of the Han people, he ordered the soldiers not to intrude, and sent people to tell the Han people that they were the king's masters. But what he didn't expect was that as soon as they left, they killed a group of people from the garden to attack them from behind, and they suffered a lot of losses because they were caught off guard, and Dong Renzhang also suffered an arrow.

Fortunately, after all, the cavalry of the police division had been severely trained, and when they reacted, they immediately surrounded and killed those men and horses with an absolute advantage, but when they interrogated the prisoners, they found that they were all Han Chinese. This made Dong Renzhang very puzzled, so he personally asked the captured leader why the Han attacked Wang Shi. The leader did not admit that he was Han, and said a few words that shocked Dong Renzhang.

"The Southern Dynasty was cowardly and could not protect its people. When did the Northern Dynasty capture the people of the Southern Dynasty and return it, when did the Southern Dynasty dare to chase after it? The Northern Dynasty killed the people of the Southern Dynasty, and the Southern Dynasty dared to retaliate? If I am from the Southern Dynasty, I will be plundered by the Northern Dynasty; I am a member of the Northern Dynasty, so I have no such worries. As long as the Northern Dynasty demonstrated against the Southern Dynasty, the Southern Dynasty plundered the wealth of the people and bribed the Northern Dynasty, and the Northern Dynasty rewarded us with the gains. It can be seen that the northerners are expensive and the southerners are cheap, what am I doing as a southerner? ”

Dong Renzhang was greatly stimulated by these words, and he loudly reprimanded the leader for forgetting his righteousness and forgetting his ancestors, and the leader probably knew that it was inevitable to die, and scolded Dong Renzhang and said: "My ancestors are the Tang Dynasty!" The Tang Dynasty is subdued in all directions, how can it be compared to such a cowardly act as the Southern Dynasty? ”

In the end, the leader was hacked to death by the furious warriors, but his words made Dong Renzhang fall into an ice cave. After telling this story, Dong Renzhang said bitterly: Where the official army passed, the Han people of Liao did not have the action of welcoming Wang Shi as he imagined, on the contrary, there were many Han heroes who led private soldiers to resist the official army, which shows that no matter how cowardly the Great Song Dynasty is, it will inevitably completely lose the heart of the Han people in Yanyun and completely lose the land of Yanyun. In the end, he shouted that Da Song could no longer be weak.

There is also a comment under the interview, the author pointed out that if the Liao people treated the Song people cruelly, but the Song people could not retaliate, they would inevitably be regarded as weak by the Liao people, and they would be bullied even more, which was also an injustice to the people of the Great Song Dynasty, especially pointed out that the hearts of the people were lost in this way.

Li Buqi flicked his hand at the position of the newspaper comment and said: "It's a pity, those people in the court who eat the ancients will find all kinds of reasons from the pile of old papers to prove that I should be gentle with the Liao people and prove me wrong." ”

Yao Gang slapped the folding fan in his hand and said: "The official's theory of 'the three emperors are lawless' is really a stroke of genius. Even the Three Emperors can't follow suit, and it's natural to question whether the things in those old paper piles are still useful. Now the debate over whether the Three Emperors can follow suit and the debate about whether they should be gentle on Yidi's unprincipled tenderness are mixed together, and there is a lot to watch. Since the official doesn't want to be promoted too quickly, then if the fire is lit at this time, he can hide from a distance and watch the excitement. ”

The guard outside the door said: "Mr. Zhu is here." ”

As soon as the door curtain was raised, Zhu Changsheng walked in and said with a smile: "It's lively now." Some people don't care about the people, but it's a big matter of face. Just now, I went around the vicinity of Guozijian with a few people, and most of the prisoners and teachers scolded the foolish people for being unreasonable, but there were also prisoners who scolded the deacons for being wasteful. ”

He lowered his voice again and said, "If it's a fire, it's a headache for the prime ministers, right?" ”
