Fortunately.

The prince here was more clever, and he stood up and saw the pen and paper that Lin Che had placed on the table next to him.

So, Lin Che said while remembering, like this, even if he doesn't understand, it will be convenient to learn later.

Regarding the prince's actions, Zhu Yuanzhang stroked his beard with satisfaction.

Today, he got a few simple fertilizer methods from Lin Che, not to mention how happy he was.

"Sir, with these methods, is it possible to increase the yield of cereals first, and then after the follow-up trial of sweet potatoes is successful, then the crisis of my Daming grain has been solved."

Zhu Yuanzhang forgot to drink and eat food when he heard it, and looked at Lin Che's eyes lit up.

I heard Lin Che say in the Imperial Prison before that the fall of the dynasty was often due to the influence of temperature in the later period, and the people did not have enough food to eat.

Now that there is a way, wouldn't it really make the Ming Dynasty for generations?

"These methods are all household methods, and it is more than enough for small farmers to be self-sufficient, and it is still far from enough to save the Ming food crisis."

"If you want to completely save Daming and promote the development of the event, you have to use pure chemical fertilizer to extract the elements needed by crops from minerals."

In ancient times, the difficulty of refining chemical fertilizers was only shocking, although he had a way, but it was still a question of whether His Majesty the Emperor was willing to take the risk to implement it.

Forget it, it was originally a small talk with the old Zhu family.

Thinking of this, Lin Che shook his head and didn't say any more, but buried himself in drinking and eating.

Zhu Yuanzhang next to him saw that Lin Che didn't mean to continue, and his heart hung in his throat again, he knew that it was difficult to save Da Ming under the temperature change, but he didn't expect it to be so difficult.

But what can be done no matter how difficult it is? Is it difficult to pick a child and quit doing it?

Everyone can say this, but he Zhu Yuanzhang can't, because he is the son of heaven of the Ming Dynasty and the king of the people.

Even he doesn't care about the fire of the people, who will have the leisure to care.

No matter how difficult it is, Zhu Yuanzhang will grit his teeth and move forward, increase grain production to benefit the people of the world, how can he ignore such a big thing.

If there is such a divine object, if you give it up just because of the slightest difficulty in refining, where will the people of the world be?

Zhu Yuanzhang clenched his fists and became more and more determined.

"Sir, I'm afraid it's very difficult to make pure fertilizer, right? No matter how hard it is, we have to do it! How innocent the people are, if they have the law and do not practice it, it is an insult to the Ming Emperor and the Ming Emperor! ”

Just when Zhu Yuanzhang was about to make a statement, Zhu Fan saw that Lin Che wanted to speak and stopped, and he was immediately impassioned and firm.

Tianxingjian, a gentleman strives for self-improvement!

The terrain is kun, and the gentleman carries things with virtue!

He Zhu Fan is willing to do this difficult thing for the people of the world.

"Good boy, I've been with Mr. Lin for a month, and the momentum of this speech is different from before, it is worthy of being our Zhu Yuanzhang's son, there is a kind!"

Zhu Yuanzhang smiled in his eyes, was extremely pleased, and gave his son a big praise in his heart.

With a family and a country in mind, I am willing to bear the hardships of the world.

He is a good son of mine!

Here, Lin Che also looked at Zhu Fan in surprise, he didn't expect this kid to say such firm words.

Looking at Zhu Yuanzhang's expectant face, he put down the wine glass in his hand and explained:

"If you want to refine real fertilizer, you first need a furnace and a Taoist priest."

"Now that the Ming Dynasty worships the Buddha and promotes the Buddha, this person and thing are still relatively easy to find."

Lin Che did not hesitate any longer, and fully revealed the prerequisites for refining chemical fertilizers.

"Daoist? Stove? ”

Zhu Zhang, who was still impassioned, was stunned when he heard this, how did this sound so much like alchemy?

Could it be that this fertilizer is actually Mr.'s alchemy method, right?

Zhu Yuanzhang was also stunned when he heard this, how did he sound unusual?

Although this Taoist is extremely mysterious, he really doesn't dare to compliment him on the alchemy technique.

Thinking of the black autumn pill-like elixir, Zhu Yuanzhang shuddered.

"Sir, we only heard that Taoists can practice the elixir that makes people immortal and ascend, but I didn't expect that this fertilizer technique is also a Taoist supernatural power."

"I knew that I had been cultivating and refining the pill since I was a child, and I would refine the chemical fertilizer pill in advance, so as to increase the grain output of my Ming Dynasty!"

Zhu Fan regretted it.

Isn't this cultivation simple, there are all Taoist bulls in the Qin Heavenly Prison, and they are mixed up with them in their own identity, so don't grow up too fast. "Who told you that fertilizer is a pill? The furnace is used to refine fertilizers, not alchemy. ”

Staring at Zhu Zhang's sighing and regretful expression, Lin Che's face turned green, this alchemy is not fun, you don't see how many emperors have died suddenly because of indiscriminate consumption of pills since ancient times.

It is rumored that Qin Shi Huang died violently because of eating those unknown pills, which caused heavy metal poisoning.

Besides, the furnace is only an element needed to refine the crops in the ore.

"And the method of refining chemical fertilizer is not a Taoist miracle, I told you earlier, chemical fertilizer, as the name suggests, is a fertilizer refined by chemistry."

"Chemistry? Isn't it a Taoist supernatural power? ”

Zhu Fan was a little confused, he thought he had glimpsed some heavenly opportunity.

"Hey, what do you want?"

"Chemistry is not a miracle, but a new discipline that mainly studies the composition, structure, properties, transformation and application of matter."

"For example, refining fertilizers involves conversion and application."

Lin Che shook his head helplessly, and immediately popularized the concept of chemistry to him.

As soon as he heard it, it was new knowledge, and Zhu Fan listened attentively.

"The purpose of these things is to refine the element of ammonia, using the soil method to coke, and after having ammonia, we will find a medium to absorb these ammonia gases and make ammonia fertilizer."

"The most convenient medium for absorbing ammonia is sulfuric acid."

Lin Che said a lot of this, Zhu Fan looked confused, and he didn't understand what Lin Che was talking about at all.

Zhu Yuanzhang and Zhu Biao were also confused.

Ballistics: These are the fairy words of the immortals?

"If you don't understand these things, you don't have to worry about them for now, just understand the soil method of coking first."

Lin Che glanced at the three fathers and sons of the Zhu family, and knew that they didn't understand what he meant at all.

"Soil coking is relatively simple, that is, the coke is stacked and put into the brick kiln and sealed for three days."

"There are a small amount of nitrogen-containing heterocycles in the coal, and in the process of refining, the nitrogen element will release the form of ammonia, which is the easiest way to obtain ammonia."

Lin Che said as concisely as possible, and Zhu Fan could barely understand a little after running rapidly in his brain.

Zhu Yuanzhang is not much better than him.

"Sir, I probably understand what you mean, that is, to get out that ammonia gas, and then find something to absorb it, can this thing be called fertilizer?"

Zhu Fan rubbed his eyebrows and thought about it seriously.

"Understood so quickly, yes."

Lin Che looked at Zhu Fan with some surprise, a person who had never been exposed to chemistry actually understood so quickly, it turned out that this kid was quite smart in other aspects besides reading.

Zhu Yuanzhang also looked at his kid, with a relieved expression on his face.

I haven't fully figured it out yet, but this kid can say one, two, three, it seems that learning from Mr. Lin is different.

If I have time in the future, I will definitely come to the lectures often to improve myself.
