At the entrance of the palace, they met many colleagues at once.

A general who was patrolling around said hello and said with a smile: "Sir Yan, isn't it just a short while after the morning court, why are you back?"

Yan Cheng was still thinking about why he said "all are back" when he suddenly saw many familiar people.

"Hey, Lao Cheng, why are you here?"

The minister wiped his tears and began to complain: "You don't know, my child doesn't know what kind of evil is possessed. I used to think that those generals could only show their bravery and only know how to fight and kill. Now he runs into the barracks every day...

…”

"Hey, the Grand Master is here too."

The ministers held each other's fists, and when they learned that the other party was also here because of Princess Ling'an, their expressions suddenly became very strange.

"Everyone is here, what happened?"

"Why did you enter the palace?"

"Don't talk yet. Let me guess. It must be because of Princess Ling'an."

"How do you know?"

"Oh, because we are all here because of this."

"Then, together?"

"Your Majesty, you don't know how elegant and polite my Ruo'er used to be, but now, he is always ready to draw a sword."

The hall was full of people crying for their fathers and mothers. The ministers complained bitterly to Princess Ling'an, which made Emperor Mingwen doze off.

"Your Majesty, Your Majesty?"

The minister's face turned red, and he looked at Emperor Mingwen: "Your Majesty, are you listening?"

Emperor Mingwen calmly came to his senses, reassured them, looked at Eunuch Chen next to him, and said, "Come here, please bring Princess Ling'an to see what's going on."

Feng Yizhi was dressed in cloth, her face was cold, and her body was still stained with mud, as if she had just come back from the fields.

Seeing her like this, some ministers were so angry that they blew their beards and glared, and immediately criticized her.

"What a decent person, what a decent person. The princess has a body of gold. It represents Ling Long's face. How come she is dressed like a woman in the field."

"Your Majesty, Princess Ling'an has violated the rules of conduct in front of the palace. I beg your Majesty to severely punish her and warn everyone. If this matter is left alone, how will the etiquette laws be obeyed by the public in the future and who will abide by them."

Emperor Mingwen also had a headache, but when he heard that they wanted to severely punish his precious daughter, he felt a little unhappy.

The ministers advised earnestly: "Your Majesty, as a member of the royal family, Princess Ling'an should set an example."

Emperor Mingwen coughed slightly, looked at Fengyi, and waved to her, his tone gentle and loving.

"Qing'er, come to me."

He deliberately kept a straight face and said seriously: "Tell me, why did you enter the palace dressed like this?"

"Father, my daughter has something to give to my father."

"oh?"

Emperor Mingwen put his eyes on the box in her hand and asked with some confusion: "What is this?"

Fengyi opened the box, and a sweet smell instantly spread throughout the hall, arousing people's appetites, and the sounds of swallowing came one after another.

The minister stretched his neck and stared curiously at the thing in Fengyi's hand.

Fengyi peeled the skin while explaining: "Father, I accidentally discovered this when I was wandering around among the people. It is sweet and delicious, so I asked the servants in the mansion to bring some to plant."

She cut the sweet potato in half and gave the other half to Emperor Mingwen to signal him to taste it.

"Your Majesty, no!"

"Wei Chen has never heard of this thing. We still need to have someone from the palace try it first to see if it is poisonous..."

The ministers looked worried and quickly stopped them.

In order to prevent anyone from poisoning, the emperor's meals were tasted by dedicated people. Even if the emperor liked a dish, if he ate a little more today, that dish would not appear in front of the emperor again for at least a month. It was extremely strict.

Fortunately for Emperor Mingwen, he gradually changed this rule after he came to power. He could eat his favorite dishes once every three days. Compared with the miserable Emperor Taishang and Emperor Taizu, he was like heaven and earth.

Fengyi took the first bite and told everyone that this thing was not poisonous.

Eunuch Chen wanted to step forward and take the sweet potatoes, but was stopped by Emperor Mingwen. He looked at his daughter with calm eyes and a smile on his lips, and started eating with her.

After taking a bite, Emperor Mingwen's eyes lit up.

It is fragrant and glutinous, and the sweetness seems to be sweet to the heart and fills the mouth.

He couldn't wait to peel off the roasted and wrinkled skin, and the golden flesh was exposed to the air, carrying bursts of heat, and blossomed into transparent flowers.

He was very fast and didn't care about getting burned, but his movements were very graceful.

Emperor Mingwen took a few bites, and he probably knew what he was doing, so he put the sweet potato aside with a smile.

Rather than enjoying this delicious food alone, he wants to know how much this thing can produce per acre? Can the whole world be fed?

Fengyi saw what he was thinking, smiled softly, and said loudly: "This thing is called sweet potato, or sweet potato. I'm not sure how much it can produce, but I'm sure it's at least a thousand catties.

"

There was a sound of gasping in the hall, and everyone's eyes widened in disbelief.

"What, thousands of pounds?"

"How is this possible? The output of this thing that I have never heard of is so high."

"This is a great event that benefits the country and the people. God bless Linglong, but is it really possible to produce an output of thousands of kilograms?" The minister's eyes were filled with surprise and doubt.

Emperor Mingwen was also slightly startled, with surprise in his eyes. If the yield per mu really amounted to a thousand kilograms, how many people would starve to death!

Then he thought of another question and said, "Is our country suitable for large-scale planting of sweet potatoes, or does it require a relatively high growth environment?"

Although he didn't understand farming, he also knew that the same crops produced in different places would have different yields.

Although the world is peaceful now and most people have enough to eat, there are constant natural and man-made disasters, either floods or severe droughts, resulting in no harvests of crops in the fields.

Moreover, Emperor Mingwen also had an ambition, an ambition to kill in the desert and prevent those foreigners from invading him for at least hundreds of years.

He could not guarantee how the future emperors would be, whether they would be incompetent, or whether the country could be passed down for generations to come, but he would at least guarantee that within hundreds of years, the people of Linglong Kingdom would be able to live and work in peace and contentment.

"Father, don't worry, my daughter has already tested it. This plant is cold-resistant and hard-working, has a low-skin nature, and has very low requirements for the planting environment. It can be grown in most places in our country."

She smiled and said: "It happens that the sweet potatoes are ripe, why don't you go and take a look tomorrow?"

Emperor Mingwen raised his head slightly, he naturally wanted to see this kind of thing for himself, after all, seeing is believing.
