Guo Jin was so excited that his eyes were about to fall out, and his cheeks were red.

"They said it worked! It really worked! ”

Guo Jin was so excited that he couldn't speak, and in the end, he only knew that he kept repeating the words "successful".

Although Zhu Di pursed his lips, Zhang Yuchu could still see a hint of joy on his face.

Woe to you.

Zhang Yuchu held the brocade box in his hand, looked at the waste pill he had practiced, and in an instant, the scene of an elixir in the courtyard not far away, which was shining golden at this time, was born in the hands of Yuan Zhenren.

It's over, Longhu Mountain is losing the adults now.

Zhang Yuchu couldn't help but tremble slightly, he had always been from his heart, and he almost wanted to kneel on the ground with weak legs to admit Zhu Di's mistake.

On the way to Nanjing City, Zhang Yuchu heard that King Yan was killing people without blinking!

Although it is not as outrageous as the "blue-faced fangs and eat a child" passed down by the Jiangnan gentry before crossing the river, this emperor who is resolute and resolute in killing is so decisive that as soon as he ascends the throne, he will kill the heads of Nanjing City, and he will kill the nine tribes, the ten tribes, and the three tribes, and all kinds of genealogy elimination packages are at your disposal, which is really ruthless!

Of course, since His Royal Highness King Yan arrived in his loyal Nanjing, the above rumors have long since dissipated without a trace, as if they never existed.

But at this time, Zhang Yuchu had already begun to regret why he had to come to Nanjing City to show his loyalty.

Now that Dan Lian is gone, it's okay.

Throwing himself into the net, stupid to the extreme.

Zhu Di looked at the black fat Taoist priest in front of him and looked a little puzzled.

"Zhang Tianshi?"

"Your Majesty, I'm here."

Zhang Yuchu's face squeezed out a flattering smile.

As the Heavenly Master of Longhu Mountain, the first priority is to preserve the survival of the Dao system, and what is not shameful is for ordinary people to see.

"I have already asked Commander Tong to go over there to take a look at the situation, and when they are finished, they will definitely leave the elixir, and when the time comes, you can come and see what the elixir they have refined is like, and then ask Yuan Zhenren what is going on."

"Yes, Your Majesty."

Listening to Zhu Di's words, Zhang Yuchu bowed his head and said yes, and at the moment of bowing his head, he closed his eyes tightly to demonstrate the pain and despair in his heart.

The Jianwen Dynasty has been suppressed for four years, and now that the new emperor has ascended the throne, the first thing he explained was messed up, is it because God doesn't bless me Longhu Mountain?

Just as Zhang Tianshi was thinking about it, another small official came in a hurry.

"Your Majesty, Mr. Jiang ended today's lecture and said three things before he finished."

"Oh? What did Mr. Jiang say? ”

When Zhu Di heard this, he asked with interest.

The diesel car did not add oil and vinegar to the face of the Chinese character, and replied truthfully.

"The first thing, Mr. Jiang said, let them first take the manufactured 'fertilizer' to go outside for experiments, select some plants with a short growth period, use the same soil, light, and water sources, and at the same time need both a control group and an experimental group, and it is best to have more than three planting fields in each group to avoid the failure of the experiment caused by a small probability accident."

"The control group means a native test plot without any other interference, that is, it can be planted as it should be planted in normal times."

"The experimental group means that the experimental plots with 'chemical fertilizer' added do not need extra care when planting."

Zhu Di nodded clearly, this is all very simple things, and he understands it as soon as he hears it. One group uses fairy prescriptions, one group does not, and then looks at the comparison results, and at the same time a variety of several pieces to avoid accidents.

"What about the second thing?" Zhu Difu asked again.

"The second thing, Mr. Jiang said that when the experiment is over, he will tell them about how the fertilizer that can be promoted on a large scale is obtained. ”

Zhu Gaochi was slightly stunned, he and Zhu Di glanced at each other, and they both saw the joy in each other's eyes.

In this way, Jiang Xinghuo is still quite confident that the 'experiment' can be successful.

"What about the third thing?" Zhu Gaochi opened his mouth and asked for his father.

Chaiche said: "The third thing. Mr. Jiang said that because he will be released from prison next year, there is no time pressure, and he is not in a hurry to give lectures every day, so he plans to change the time of lectures to once every 15 days in the future. ”

When Zhu Gaochi and Zhu Di heard this, their faces relaxed.

According to the previous class intensity, one class a day, the two of them have to deal with the government and politics, and they have to rush over every day to listen to the class.

And Jiang Xinghuo now plans to change the interval between the last classes to 15 days.

Now it is the end of August, and next year will be the middle of January, and then the year name will be changed to amnesty to the world, so it will be September, October, November, December, and January, which is five months smaller, less than 150 days.

In other words, there are 9 more lessons!

Jiang Xinghuo was in prison, and he would take the last 9 classes, and he would end his lecture in prison.

But Zhu Di thought about it, then frowned, and muttered: "Is this not okay?" I always felt that only nine classes were too little. ”

Zhu Gaochi coughed dryly and reminded the greedy father.

"Father, Mr. Jiang can also talk about it after he is released from prison, and it doesn't mean that he won't talk about it when he is released from prison, but he may have to do some other things that he proposes himself, but it doesn't mean that he can't give lectures in his spare time."

Zhu Di waved his hand and said, "That's different!" ”

"Assuming that Mr. Jiang didn't see through it, then when he didn't know the identities of the people around him and didn't know that someone was eavesdropping, what he said must be more real and bold. If you don't have this layer, you won't necessarily be so interesting and rewarding in the future. ”

"Then we'll listen to it too, we've been listening to it for so long, we're used to it, aren't we, father?"

Zhu Gaochi said with a smile: "What's more, as long as Erchen thinks about it, if Mr. Jiang really doesn't know all this, when he is released from prison next year, he doesn't know what kind of expression he will have when he sees that his cellmate is actually Cao Guogong, the second prince of the dynasty and the head of a hundred officials." ”

"Hahahaha!"

Zhu Di thought of Jiang Xinghuo's stunned face, and also laughed, and joked.

"Then think about it, when you think about it next year, the Ming treasury bonds have been issued, and the apportionment into the mu has also been promoted, and the things of supporting the clan, going to the West, and conquering Japan are also in preparation. Mr. Jiang saw that the scenes that he didn't expect to achieve in prison appeared in front of him, and this kind of thing was extremely interesting when I thought about it! ”

Hearing Zhu Di's ridicule, Xia Yuanji, the head of the household who was dressed in a scarlet robe, couldn't help but laugh at this time, and suddenly, he was also looking forward to it.

——What kind of psychological activity would it be if Jiang Xinghuo came out of prison and saw a notice on the door of the household department selling Daming treasury bonds.

"So, my father doesn't need to worry." Zhu Gaochi said with a smile, "No matter how Mr. Jiang lectures, let's go to the lecture anyway, what's the difference between listening to a few classes?" Moreover, Mr. Jiang's class arrangement just gave us plenty of time to do other things. ”

Zhu Di nodded in approval and said, "Yes, I was worried that after Mr. Jiang was released from prison, he would not be willing to give a lecture." Now that I think about it, I'm worried too much. ”

During the conversation, Yuan Hui, who was dressed in sackcloth and had white hair, walked over with the fertilizer that had been successfully refined over there.

"I have met Your Majesty, His Royal Highness the Great Prince."

Yuan Hui first saluted Zhu Di and Zhu Gaochi, and then looked at Zhang Yuchu, the contemporary celestial master of Longhu Mountain.

Zhang Yuchu's purple-black face showed a friendly smile, and he said again and again: "Yuan Zhenren, don't come unharmed!" ”

As the leader of the Daomen, Zhang Tianshi naturally wants to suppress other schools, but old-timers like Yuan Hui, the world's first phase master, who are highly respected and have no sects, are extremely respectful.

What are the rivers and lakes, and the sophistication of human feelings is the rivers and lakes.

If you don't show respect for the old-timers to the people in the circle, who will respect you when you get old?

After the two of them met.

Zhu Di groaned slightly, and then said: "I remember, Zhang Tianshi once said that what other alchemy Taoists can refine, you Dragon and Tiger Mountain can also refine?" ”

Zhang Yuchu hurriedly bowed down and said, "Yes, the minister does not dare to hide His Majesty." ”

Zhu Di said with a slight suspicion: "I heard that the formula of this elixir for you is exactly the same as that of Yuan Zhenren?" Don't fool me, or else, huh——! ”

"Don't dare!"

Zhang Yuchu was stunned in his heart, and hurriedly patted his ass from the bottom of his heart and said: "Your Majesty's holy life is boundless, and the blessings will last forever!" If there is something different, it must be that our Dragon Tiger Mountain alchemy technique is not enough, but it is definitely not deliberately deceived Your Majesty! ”

After scaring Zhang Tianshi, Zhu Di motioned for Yuan Jue to present the elixir he had refined over there.

Yuan Gong stretched out his hand and handed the wooden box containing the elixir 'fertilizer' in his arms to the eldest prince next to him, Zhu Gaochi.

Zhu Gaochi changed his hand and presented it respectfully.

Zhu Di stretched out his hand to pick up the wooden box, opened the lid and took a look, only to see five pale yellow pills lying inside, about the size of a thumb belly, and the color was not transparent, and it didn't even look outstanding.

Well. This is because of the simplicity of the experimental equipment, there are too many impurities in the solid ammonium sulfate, and the dissolution of ammonium sulfate is very large and affected by temperature, it should be gray-white normally, but because there are trivalent iron and other substances, it is unpurified recrystallization, so it is light yellow.

In this case, it is generally possible to add 3-5% dilute ammonia blisters in the laboratory for a few minutes, and then centrifuge and spin dry. But considering the current scientific and technological level of Daming, there is not even a drum washing machine, so it can only rely on the simplest stupid method, that is, repeatedly dissolving, cooling, and recrystallizing for purification.

But it doesn't matter if it's pure or not, it's not the king of Litang, just use it.

The pill looks, except for the different colors, what Zhang Tianshi refined is reddish gray, this one is light yellow, and the others don't seem to be any different?

Even the pungent smell of gas is exactly the same.

Zhu Di and Zhu Gaochi glanced at each other, and they both felt a little surprised.

Zhu Gaochi whispered: "Father, this pill is the same as the pill refined by Zhang Tianshi, except for the different colors." ”

"That's true." Zhu Di pondered for a moment, nodded and said: "Since the elixir refined by the two real people is almost the same, I can't be partial to anyone, and if I don't put it in the farmland for comparison, it's hard to say that what Zhang Tianshi refines must be a failure." ”

Hearing this, Zhang Yuchu breathed a sigh of relief, and fine beads of sweat had already appeared on his forehead, which showed how much pressure Zhu Di had put on him.

Zhu Di stared at the pill carefully for a while, and suddenly said, "Yuan Zhenren, has Mr. Jiang ever told you, is it a success if the pill becomes like this?" ”

Yuan Jue replied: "That's right, that's it." ”

At this time, Zhang Tianshi, who was considered to have successfully passed the test in the emperor's place, finally had time to start his thoughts.

"Do you think there really is any immortal recipe, in the end, aren't all the things refined the same except for the color?"

"Hey, the emperor is really easy to fool, this kind of road that is obviously a charlatan will be fooled."

"This Heavenly Master has been alchemy and drawing talismans for so many years, and I have never seen such an outrageous Dan Fang."

"Green alum is used as a medicinal material, mainly for the treatment of laryngeal paralysis, tooth sores, scabies. It can also eliminate stagnation, dry spleen and dampness, dissolve phlegm and salivation, and remove swelling. ”

"But what can soot do? Choking your throat? ”

"Take soot and pour it into the alum liquid, why don't you take the gold juice and pour it into the mercury?"

Just when the black fat Taoist priest was complaining in his heart, Zhu Di issued an eviction order.

"Zhang Tianshi, Yuan Zhenren, you two go back first, and I will summon you to see the results in a few days."

Zhang Yuchu and Yuan Heng naturally didn't dare to disobey, and after the two left, only Zhu Di, Zhu Gaochi and Xia Yuanji were left in the empty courtyard.

Zhongyiwei commanded Tong Xin to guard the gate of the courtyard with his soldiers, while Guo Jin and the firewood cart went back to continue to sort out "Mr. Jiang's Lecture Notes".

In front of Zhu Gaochi and Xia Yuanji, Zhu Di finally revealed a little bit of his true emotions.

Zhu Di was a little skeptical.

Zhu Di looked at the gray-red and light yellow pills in front of him, revealing a deep groan, and asked without turning his head.

"Chi'er, do you think Mr. Jiang's elixir called 'chemical fertilizer' can work?"

Zhu Gaochi was actually not so optimistic, he said with some hesitation: "I haven't tried this, and Erchen doesn't understand it very well, but Erchen thinks that since my father believes in Mr. Jiang, then I still have to do it with the idea that I can do it." Erchen thinks that this thing, since Mr. Jiang is so sure, it should be very reliable. ”

Zhu Di nodded and said, "What you said also makes sense, it's just."

Xia Yuanji couldn't help but say, "Your Majesty is too worried, right?" The minister is quite confident in this. ”

"Alas"

Zhu Di sighed faintly, stood up and walked to the edge of the courtyard, looked at the scenery of Zhongshan in the distance, and fell into a long silence.

Zhu Gaochi also paced, he found that his father was very worried today, and he immediately guessed the reason - his father was both hesitant and hesitant about the 'fertilizer' elixir.

After all, such a thing, in anyone, I am afraid that they will subconsciously feel unbelieved.

As of this year, in the thousand-year-old history of China and countless dynasties, no one dares to say that in this world, there are things that can double the yield of crops per mu as long as they are sprinkled.

Because before that, there really wasn't such a thing.

Therefore, the limitations of the times still limit the imagination of the highest levels of the Ming Empire.

How can you be sure of things that have never appeared?

Although Zhu Di is the king of a country, this kind of thing still makes him feel a little bottomless.

The handling of such things often determines the well-being of tens of millions of Li Shu people. And the outcome of this decision may affect the future Ming Dynasty and directly determine the rise and fall of a generation of dynasties.

Even Zhu Di will feel a little nervous and apprehensive.

But Zhu Di is Zhu Di after all, and he fought out in countless swords and blood.

This emotion, which affected his decision-making, began to be left behind by him.

However, Zhu Gaochi did not feel Zhu Di's thoughts in time, and he planned to persuade him out of the consideration that he did not want to see his father so entangled.

"Father." Zhu Gaochi said suddenly, "You don't have to take this matter too seriously, let's just do our best and listen to the destiny of heaven." ”

Zhu Di stopped, turned his head and said, "Chi'er, do you really think so?" ”

Zhu Gaoxu said: "Father, the son is telling the truth, the son really thinks so." Although the elixir may not be successful, there is nothing to lose in the end, as long as the father does not place too high hopes, if it succeeds, everyone is happy, but if it fails, Daming is actually not adversely affected. Erchen pondered repeatedly, if he succeeded, it would be good, if he failed, his father would have to consider another matter about agriculture. ”

Xia Yuanji also persuaded and said: "The minister also believes that since Master Jiang is so determined, then there is really such an immortal recipe in this world that can double the yield per mu of farmland, and the minister thinks it will not be wrong!" ”

Xia Yuanji paused for a moment, and then said: "Your Majesty, after the ministers go back, gather the officials in charge of agricultural affairs to study it together, and then select a few fields in the imperial village to try to cultivate, and when there are results, it is not too late to draw conclusions." ”

After the two finished speaking, they quietly waited for their father's decision.

"I understand."

Zhu Di finally let out a long breath and turned back, "I'm just a little concerned and it's messy, so let's do as you say, I'm done." ”

"Thank you, Father!" Zhu Gaochi suddenly smiled.

"The minister immediately went to gather officials and selected ploughed fields in Huangzhuang for experiments." Xia Yuanji also said.

Zhu Di asked, "What crops does Xia Qing plan to use for experiments?" ”

"The growth cycle of rice and the like is too long, so we need to use vegetables with a short growth cycle, that is, camellia, small rape, sprouts (bean sprouts), oily lettuce, amaranth, and green garlic."

Xia Yuanji almost didn't hesitate, and said the answer in his mind.

Zhu Di thought for a while, and then asked, "How long are these growth cycles?" ”

"90 days for shepherd's cabbage, 50 days for small rape, 7 days for sprouts (bean sprouts), 40 days for oily lettuce, 45 days for amaranth, and 50 days for green garlic." Natsuhara replied.

"Try them all, but focus on the sprouts."

In the face of the emperor's instructions, Xia Yuanji could only nod.

Here, Zhu Di instructed Xia Yuanji to use chemical fertilizer to grow vegetables, and on the other side, Jiang Xinghuo also received an unexpected letter after class and met an unexpected person.

"You said this is a letter from a friend of Yuan Jushi?"

Jiang Xinghuo looked at the letterhead in his hand and asked strangely.

Li Jinglong nodded, and Yuan Jue was behind him.

Well, what Li Jinglong didn't say was that this friend of Yuan Jushi was called Daoyan.
