"Hey, hey!"

Zhu Fan touched his nose embarrassedly, Lin Che's praise for him was far more important than the teacher's praise from childhood to adulthood.

The key is that his father's expression is different from the past.

I used to treat myself either by beating or scolding, but today I look at my father's eyes, and they are actually very soft.

is not as fierce as in the past, this vision was only exclusive to the queen mother and the prince's brother before.

Zhu Fan couldn't help but feel proud in his heart.

"And sir, how should this sulfuric acid be made?"

Zhu Fan didn't know much about these things, so he asked shamelessly.

"There is also a simple way to make sulfuric acid, and if the conditions are not enough, we will use it first."

"The most important thing is to find the green alum, which is bile alum, and then set up a pot and burn it directly."

"But what needs to be noted is that the container for this object, the iron pot is absolutely impossible, but the ceramic vat is doable."

"This process also has a chemical name, that is, dry distillation, so that the refined is concentrated sulfuric acid."

"Then get some water into the tank to dilute it, and then find a pipe to pass the gas from the previous soil coking method into the water tank, and the thing in the water tank at this time is called ammonium sulfate..."

"At this point, it can be used as fertilizer, but the liquid is always a little difficult to transport, or the old way, you can also directly light the fire and boil the water dry, so that you can get solid ammonium sulfate."

Lin Che talked eloquently, and some of the popular science knowledge books he read before crossing now play a role.

These knowledge points can also be remembered clearly, although they were not able to see it come in handy, but they were said and taught to the most powerful family in the Ming Dynasty.

After all, only they can spread their knowledge and contribute to Huaxia.

Refining chemical fertilizers and developing explosives are actually somewhat similar, and starting to refine chemical fertilizers now can be regarded as making some contributions to the development of science and technology in later generations.

When Lin Che said this, he picked up the wine that Zhu Yuanzhang poured for him at some point and drank it slowly.

As for not being able to use an iron stove because sulfuric acid is extremely corrosive and will have a chemical reaction with iron products, this thing is too profound, so I didn't say it, and the three fathers and sons of the Zhu family wouldn't understand!

"It's so complicated! I see, according to what Mr. said, you should find someone to be familiar with it and you can refine it, so why bother looking for a Taoist priest? ”

As soon as this question was answered, the next question appeared in Zhu Fan's heart.

Zhu Fan felt that he was now like a child, full of thirst for knowledge, with a hundred thousand whys.

Thereupon.

Zhu Fan opened his mouth again to ask his doubts.

"Looking for a Taoist priest is because refining sulfuric acid is life-threatening, if I remember correctly, this thing should be called alum oil now, the Taoist priest is familiar with this thing, he knows it in his heart, and the technology is in place, refining sulfuric acid should be regarded as a familiar road for Taoist priests."

"The concentration of alcohol and sulfuric acid is very high, and as long as this thing is stained, it can corrode to the bone in an instant."

Ordinary people really can't cope with it, which is why Lin Che insisted on finding a Taoist priest to refine.

"Sulfuric acid is alum oil? Isn't alum a drug? ”

Zhu Fan was taken aback when he heard this, and said that this was not a Taoist supernatural power.

He clearly remembered that one day, a Taoist priest took the elixir refined by green alum to pay tribute to his father, and his father laughed at the time and rewarded the Taoist priest with thirty plates.

Zhu Yuanzhang and Zhu Biao glanced at each other, they knew much more about green alum than Zhu Zhang.

Of course, he knew that green alum was a drug, and as for whether it was poisonous or not, Zhu Yuanzhang had never tried it.

"And what is this bile? Could it be that it was also invented by Taoists? ”

The more Zhu Fan thought about it, the more he felt that it was possible, and hurriedly asked Lin Che.

"Alum? This thing should be called stone gall in the folk. ”

Lin Che frowned, this thing seems to have only been discovered in later generations, right?

No, this thing seems to be called stone gall in ancient times.

"It turned out to be one of the five poisons."

Zhu Fan suddenly realized, he was still wondering what it was, it turned out to be the stone gall in the idiom with all five poisons.

The remaining four poisons are:

Dansha, realgar, alumite, magnet.

Here, Zhu Yuanzhang felt like he had taken a reassuring pill.

The Ming Dynasty is rich all over the world, and it is not easy to find a Taoist to refine a pill, not to find a Taoist to refine a fertilizer.

There is such a simple way to benefit the people.

Here, Zhu Biao excitedly put down the pen in his hand, and his excitement was irrepressible:

"Sir, if this thing is refined, you will be a grace to the Ming Dynasty and the people of the world! I think every family will build a temple for you by then! ”

"You will be a great sage who surpasses Confucius and Mencius!"

Zhu Biao was excited for a while, but he was not patting on the back.

It's this kind of cross-era artifact that can really make Lin Che ascend to the sky in one step.

Every person who created the era will be remembered by you and the people.

Lin Che will be the first person to create an agricultural era!

"I'm afraid that the reincarnation of the gods is nothing more than that, it seems that I am going to produce a great sage, a great immortal!"

Here, Zhu Fan also stood up with admiration and said.

When I think about it, I am extremely proud, at that time, he will be the first disciple of the Great Sage.

Hey, even if I, Zhu Zhang, am just an ordinary person, it is easy to climb the towering tree of Mr. and leave a name in history!

Thinking of this, Zhu Fan looked at Lin Che with the same eyes as if he was looking at a land immortal.

"What a great sage, a great immortal, exaggerated!"

Lin Che waved his hand and smiled, although he could see that Zhu Fan was sincerely praising him, Lin Che still had no waves in his heart.

"Don't be so excited, let's talk about those things if you can get them, this method is not easy to develop chemical fertilizers, and it still needs the full support of His Majesty the Emperor to be effective."

Lin Che looked at Zhu Yuanzhang, and Lao Zhu knew that it was time for him to express his position.

He put down the wine glass in his hand and arched his hand:

"Mr. Lin, you have worked hard for me and pointed out the maze, we have nothing to say, we must develop the fertilizer that Mr. said."

"For the benefit of the people and for the benefit of future generations."

"We have Mr. guidance, and we will definitely prosper and flourish."

"Our old Zhu has nothing to say, Mr. Jing has a cup to show his gratitude, Mr. please!"

Zhu Yuanzhang picked up the wine glass, stood up and drank it all.

Seeing that His Majesty the Emperor was so polite, Lin Che couldn't go too far, so he had to stand up and accompany the glass of wine.

"However, with fertilizers, grain production can be increased, but not completely."

Lin Che's turning point made the originally fiery hearts of the Zhu family's father and son pour a basin of cold water.

"Even if chemical fertilizers increase food production, what if there are still pests? It is important to know that pests have always been the worst enemy of food production. ”

It is recorded in the history books that the reason why the people were displaced at the end of the Yuan Dynasty and that uprisings emerged one after another, in addition to the excessive oppression of the people by the imperial court and the gentry, was that there were insect plagues in those years, and the grain output was only one-tenth of the previous year, and the peasants could only choose to flee or take up arms to launch an uprising in the face of natural and man-made disasters.

"Sir! Since you say so, there must be a solution, to control the pest! ”

Zhu Fan has been studying with Lin Che for so long, and he can be regarded as knowing something about him, since he has raised this question, there must be a way to solve it!
