Huang Yan coldly watched Zhu Zhanji use the emperor's paper and pen, and secretly wrote down this detail in his heart.

Zhu Zhanji's handwriting was taught by Zhu Di himself, but Zhu Di frowned when he saw some winding characters.

After Zhu Zhanji finished writing, he said excitedly, "Grandpa Huang, I went to the Imperial College and the Ministry of household today and compared the records on both sides. As a result, I found some food secrets."

Zhu Di looked at this magnificent grandson, and the idea that had just come out of his heart dissipated again.

"Since the three generations, the grain yield per mu has been a festival. On festivals, the yield per mu in the former Han Dynasty was 2.82 stone, while the yield per mu in the former Tang Dynasty was equivalent to 3.81 stone made in the Han Dynasty..."

Hearing this, Zhu Di's face moved a little.

"... in the former Song Dynasty, the yield per mu was equivalent to 4.8 stones made in the Han Dynasty..."

Zhu Zhanji picked up the rice paper and said in high spirits, "Grandpa Huang, in my Daming, the yield of Winter Wheat in the north is no more than 1.5 stone per mu made by the Han Dynasty."

"So low..."

Zhu Di pretended not to worry.

Zhu Zhanji said with a smile: "Grandpa Huang, many in the north are already summer wheat and autumn millet. The yield per mu is 3.2 stone made by the Han Dynasty, which is a lot."

Zhu Di's eyes were more and more relieved, stroking her long beard and listening with a smile.

Zhu Zhanji grabbed the back of his head and said in a kind of way: "it's just that the yield per mu in the south is a little messy, some are two seasons, some are one season, but it should be much higher than that in the north. Grandpa Huang, is that why the south is rich and the population is increasing?"

"Ha ha ha!"

Zhu Di got up and laughed, very pleased.

Huang Yan's eyes flashed a trace of resentment. Seeing Zhu Di happy, he also joked: "Your Majesty, your highness TAISUN is talented and intelligent, but what are these twists and turns?"

Zhu Yuanzhang never allowed eunuchs to interfere in politics, but when he came to Zhu Di, even if he reiterated this national policy many times, he was conniving at the eunuchs himself.

Zhu Di's laughter was stifled and his eyes turned to Zhu Zhanji.

Zhu Zhanji disdained at the corners of his mouth, and then said, "Grandpa Huang, this is another thing I want to tell you."

"When I went to the household department today, I saw that the characters recording numbers were cumbersome and inconvenient to calculate, so I used Professor Fang Dehua's big food digital records."

Zhu Zhanji handed the rice paper to Zhu Di's eyes and said, "Grandpa Huang, look here. Is it clear at a glance and easy to calculate!"

Zhu Di took the rice paper and hesitated: "it's refreshing, but what you said is convenient for calculation, is there evidence?"

Huang Yan bowed his head and turned his gloating eyes to the ground.

Zhu Zhanji smiled and said, "Grandpa Huang, look."

The formula was immediately listed on the rice paper. Zhu Zhanji added all the yield per mu, and then divided it by the number of dynasties.

"Grandpa Huang, you see, this is the average yield per mu for several generations."

Seeing that Zhu Di was still thinking, Zhu Zhanji called a small eunuch and said, "you can report the number to me at will, and then you can ask for the sum or subtraction."

How dare the little eunuch? At last, Zhu Di nodded. Only then did he report the numbers tremblingly.

A quarter of an hour later, several rice paper were full of numbers, and Huang Yan's mouth couldn't close.

Zhu Di felt that today was the most pleasant day in recent days. He shouted to reward the emperor's grandson. He almost sent out his emperor's sword, but he didn't mention Fang Xing's name.

In less than half an hour, today, the emperor's grandson was praised by his majesty, and it spread to those who should know.

In Tai's womb, Zhu gaochi waved back the eunuch who read the memorial to himself and murmured, "my son has really improved..."

"Someone."

"Your Highness."

"Ask the crown princess to check the people on TAISUN's side, especially the people who follow TAISUN out. If there is an unknown origin, send them away!"

……

"Bell, bell..."

In the backyard of fangjiazhuang, Xiaobai is looking for the lost bell in the yard.

Zhang Shuhui was busy for a long time and finally collected all the people in Chuang Tzu. She sat on the newly made Kang, stretched a graceful stretch, and then woke up and said angrily to Fang, who had just turned into a gentleman: "husband, it's still day!"

"Cough!"

Fang Xing took back his eyes and said solemnly, "has the teacher Taishun found for Ma Su arrived?"

There's nothing to talk about!

Zhang Shuhui woke up with a white look: "he arrived the day before yesterday, but Mr. Li doesn't want to live in the villa. I'll ask someone to pick him up in the city every day."

This Li Chongxin was born as a Jinshi. However, after Ding you returned to his hometown, the Ministry of officials had no arrangement at all, so Zhu Zhanji came to teach Ma Su the way of imperial examination.

But the gentleman was not very safe. Yesterday, Zhu Zhanji came to the villa. He pretended to meet by chance, and then made a gesture of worrying about the country and the people.

"That's an official fan. Let him go next month."

Fang Xing felt that his disciples should not be taught by such people, so he was ready to discuss with Zhu Zhanji to see if he could let Ma Su study in the Imperial College.

"It's a small thing! Leave it to me."

Zhu Zhanji was praised by the emperor. The next day he came to the villa and brought some gifts, including a group of live birds.

There was a flurry of chickens and dogs outside the front yard. The bell was fiercely chasing these chickens and ducks. The scene was in chaos.

Fang Xing didn't miss the schadenfreude on Zhu Zhanji's face, so he decided to add half of today's homework.

"Bell, come back!"

There was no rule that women and children could not go out of the backyard in the Fang family. Fang Xing even encouraged women to go to the village.

It was easy for Xiaobai to hold lingdang, and the milk dog shouted at Zhu Zhanji in her arms.

Fang Xing quickly asked the farmers to drive away the chickens and ducks, and then asked to build a chicken house and duck house behind the main house.

"The chicken manure and duck manure cleaned every day are not allowed to be thrown away. It's just a fertile field."

Zhu Zhanji looked at Fang Xing, who brought glory to himself. As his "teacher", Fang Xing could at least get a fat position in Jens house. But he didn't want to go and would rather deal with these chickens and ducks in the countryside.

"Hurry up and clean up the feces at the door."

Fang Xing stepped on a pile of chicken droppings. He frowned, took off his shoes, and then bent down to scrape them on the ground.

Snatched the bell from Xiaobai's arms, Fang woke up, held its forehead and said fiercely: "bell, I can see clearly later. I'll catch all the chickens and ducks who dare to shit in the main house."

The little suckling dog purred a few times, and I don't know whether he understood the spirit of the owner.

When he got to the study, Ma Su hurried to see his neck was a little crooked. Fang woke up and frowned, "didn't he let you read?"

At this time, we should pay attention to posture when reading aloud. We must turn our head with the literal rhythm and rhythm for a long time

"I have lost another carsick and seasick person since the dawn of the Ming Dynasty. Congratulations!"
