After going back, Zhu Youzhen also considered how to make Daming's own fertilizer.

Later, he studied it and gave up, this thing seemed to be difficult.

Well, actually, he doesn't have that level at all. However, it can be used as a research direction to lay a foundation for the future.

Then he thought of another person:

Song Yingxing

Another big bull at the end of the Ming Dynasty.

He was in the history books when he was in school.

Although he did not achieve good results in the imperial examination, he left an outstanding work for future generations, "Heavenly Works". Zhu Youzhen bought a copy from Xixi, and was deeply shocked just by reading the catalog.

The book is divided into three volumes and eighteen chapters, which describe a variety of production techniques. The first article records the cultivation of grains in the world, which is quite normal. But chapter 14 deals with the mining and smelting of metals, and chapter 15 is even more outrageous, describing how weapons were made (including how gunpowder was made!). ）。

Zhu Youzhen can't wait to meet him, does he also have a system? How can anything?

Now the time for the examination has passed.

"Wang Banban, you send someone to help me find someone. This person is a famous person, named Song Yingxing, a native of Waxi Archway, Fengxin County, Jiangxi. At this time, you should take the entrance examination in the capital. If he falls off the list after the release of the list, bring him to see me. ”

"Slave and maid command!"

There are still more than ten days left before the trial release list, so you can just make some preparations in advance.

He also bought textbooks on mathematics, chemistry, physics, biology, etc.

From elementary school to high school, all set!

He was going to throw these books to Song Yingxing and give him a collision between modern civilization and ancient science. See what kind of sparks can be created.

Next, Zhu Youzhen was even busier. Not only did he have to sort out the knowledge in his textbooks, but he also had to translate all the simplified characters into traditional Chinese. This is a huge project, but I can't let others do it for me, and I am dizzy and dizzy every day, and it is extremely painful.

A few days later, he finished translating elementary school math and finally couldn't help it anymore and decided to go out for a spin!

Where to go? He consulted Zhou Yufeng's opinion.

Zhou Yufeng was a little curious about the last time he went to Zhang Erhu's house, so he asked him if he could go to Shunyi Huangzhuang to have a look. Zhu Youzhen naturally didn't have any opinions, and just took the opportunity to see how the fertilizer was applied.

So, Zhu Youzhen took the queen Zhou Yufeng and Li Xiaohua to secretly leave the palace under the secret protection of the guards.

More than an hour later, the two carriages arrived at the Shunyi Huangzhuang.

Zhu Youzhen got out of the carriage first, breathed a breath of fresh air, and swept away the fatigue of the past few days.

These days, it's been sunny days, and the snow has long since melted. As far as the eye can see, there are green wheat seedlings, which look vibrant. The ground is no longer muddy, and there are more children playing, but most of them are unable to help in the ground.

Li Xiaohua jumped out of the car excitedly and ran to play with the children in the village. Zhou Yufeng wanted to call him back, but was stopped by Zhu Youzhen.

This child is suffocated in the palace, and it is good to run.

But after a while, Li Xiaohua came back, pouting aggrievedly.

Zhou Yufeng asked her what was wrong, and she said aggrievedly:

"None of them play with me."

"Why?"

"Humph! They're too stingy! After saying that, he grimaced at the children in the distance.

In fact, Li Xiaohua blamed others, she was dressed delicately and luxuriously, like a porcelain doll, not very proficient in official dialect with a strong northern Shaanxi accent, who would dare to play with him?

The three of them walked to Zhang Dahai's house, and were about to call someone, when a young voice came from behind them.

"Your Majesty?"

Zhu Youzhen looked back and saw that it was not Zhang Erhu.

Zhang Erhu was carrying a kettle, and when he saw that it was really Zhu Youzhen, he hurriedly rushed over. But I remembered that my father said that he was going to kneel down when he saw the emperor, so he stopped halfway and kowtowed on the ground.

Zhu Youzhen was amused by his series of actions.

"Get up, get up. No need to kowtow. ”

"Alas!" Zhang Erhu got up with a bone, came to Zhu Youzhen, glanced at Zhang Xiaohua and Zhou Yufeng, and asked with a raised face:

"Your Majesty, why are you standing at the door and not going in?"

"I was about to tell you to open the door, and you came back."

"Why are you telling me to open the door? My dad said the whole world is yours. We are all yours too. ”

"The world is mine, but the family is yours." Zhu Youzhen looked at the kettle in his hand. "Why are you carrying a kettle?"

"Oh, my mother is thirsty, I'll come back and pour her some water to drink."

"Go and pour it, and I'll go to the field with you in a while."

Zhang Erhu ran quickly into the house, and there was a sound of talking inside, and he ran out again after a while.

"Let's go."

A group of people slowly walked into the field. Zhu Youzhen looked at the scenery and said a few words to Zhou Yufeng from time to time. It was Zhang Erhu, who was surprisingly quiet along the way, and secretly glanced at Zhang Xiaohua from time to time. Zhou Yufeng snickered when he saw it.

After a while, Zhang Dahai came to bow his head. Zhang Dahai pulled the cocoon, and Zhang Wang pushed behind. It looks like it's fertilizing.

Zhang Erhu shouted loudly, and the two turned around and saw two people standing on the ground.

Zhang Dahai took a look, Mom! Your Majesty!

Hurriedly pulled Zhang Wang's and ran over.

However, before he could salute, he was stopped by Zhu Youzhen.

"Are you fertilizing?"

"Back to Your Majesty, it is the fertilizer given by Your Majesty!"

Zhu Youzhen squatted on the ground and looked at the green wheat ridges, some of which had been dressed in chemical fertilizer.

"Has everyone fertilized?"

"Shi, today is just my turn to use the family, and I have to give it to the next family when I run out. Everyone thanked His Majesty in private, saying that His Majesty was merciful and did not raise the rent after sending so many things. ”

Zhu Youzhen smiled.

"Fertilizer has a big effect, and there will be a good harvest this year."

Zhang Dahai wiped the sweat from his head and nodded with a grin. The more food you produce, the more you can eat, the more you eat.

Zhu Youzhen chatted with him for a while and then asked him to continue working, the cocoon is used in rotation, and he can't delay others to work.

Taking advantage of their work, he took Zhou Yufeng around, and the green wheat seedlings everywhere made people feel refreshed. When this season's wheat harvest is abundant, plant another season of potatoes, so that everyone can see the yield of potatoes, which is estimated to be of great help to promote planting.

At noon, I ate at Zhang Dahai's house, saying that it was eaten at his house, but it was actually the meal that Zhou Yufeng ordered the imperial dining room to prepare in advance and brought it in the food box. Simply heat it up and eat it.

During dinner, he finally met Zhang Dahai's daughter Zhang Rulan. Although he is dressed plainly, he is childish and cute. No wonder Steward Xu never forgot it when he saw it, and he also took his life for it.

After eating, several people embarked on the way back. When Zhang Erhu saw Li Xiaohua leaving, he was almost lost. Zhang Wang couldn't see his thoughts, sighed and didn't speak.

It is often said that once a person has money in his hand, he is prone to swelling. Now Zhu Youzhen feels like this.

Wei Zhongxian got more than 27 million, Wang Chengen got more than 900,000, and copied hundreds of thousands of homes, adding up to nearly 30 million.

There is no point in putting money there, you have to find a way to spend it.

No, he found Bi Maokang again.

I'm going to see how his research goes.
