I have already established my power and prestige, so how did Li Shimin come back to life?

After hearing Chen Fusheng's definite answer, Wei Zheng seemed to have lost his support and sat down on the ground.

Tears streamed down his face, his voice choked with sobs: "God bless our Tang Dynasty! Normally, a yield of one dan of wheat and millet is considered a bumper year! Now the yield of sweet potatoes alone is 1,500 jin, which is almost 15 dan of grain!

This is a treasure bestowed upon the Tang Dynasty by Heaven! Good days are coming for the people of the Tang Dynasty!

With these things, our Tang Dynasty will no longer be afraid of any natural disasters or man-made disasters!

People no longer have to suffer from hunger, and no longer have to watch their loved ones starve to death!"

Wei Zheng had completely lost his composure. This old minister, who had always been upright, calm and composed, was now sitting on the ground like a child, crying and laughing, ecstatic about the future of the Tang Dynasty. It was a sincere hope that the people could live a good life.

Fang Xuanling looked at Wei Zheng, and although he was also very excited, he tried hard to control his emotions. He was old and was afraid that something unexpected would happen if he got too excited.

He calmed himself down and said to Chen Fusheng, "Master Chen, since the sweet potato yield is already so high, what are the yields of corn and potatoes?"

This time, everyone held their breath, not daring to make a sound. They pricked up their ears and stared at Chen Fusheng without blinking, as if he was about to reveal a secret concerning the life and death of the Tang Dynasty, and they were afraid that he would miss some important information.

"The yield per mu of potatoes and corn is not as high as that of sweet potatoes. The average yield per mu of corn is about 700 kilograms, and the yield per mu of potatoes is about 1,200 kilograms."

Chen Fusheng said.

"As for why we don't plant only sweet potatoes, it's because of the Academy of Sciences' regulations. People can't eat sweet potatoes all the time. Although sweet potatoes can solve the problem of hunger, if you only eat sweet potatoes for a long time, the body will lack some necessary nutrients, and then you will get sick."

"You can eat more potatoes, but you'll get tired of them if you keep eating them. So rotating the three crops is enough to keep people alive and healthy.

These new terms, such as the Ministry of Agriculture, Academy of Sciences, Nutrition, and Research, were somewhat unfamiliar and difficult to understand for these old ministers of the Zhenguan period, but they all knew clearly at this moment that these three kinds of grains were life-saving gifts from God to the people of the Tang Dynasty. They were the light of hope for the prosperity of the Tang Dynasty and the foundation for the long-term stability of the Tang Dynasty.

"Long live His Majesty! If these three crops are true, it is truly an auspicious sign for the Tang Dynasty!"

Fang Xuanling bowed slightly, and his solemn court robes swayed gently with his movements.

His voice rang out in the quiet court, with a hint of excitement, and his eyes flashed with anticipation for the unknown, like a child who saw a treasure.

The atmosphere in the court was slightly shaken by his words. The ministers around him nodded and started talking among themselves. Their voices buzzed in the empty hall.

Li Chengqian sat upright on the dragon throne, his eyes as deep as the abyss, making it difficult for the ministers to understand.

He glanced at Fang Xuanling, his eyes calm and majestic. His gaze was as real as substance, instantly quieting the noisy court, like a gust of cold wind passing through a bustling market.

"Prince Fang, there is no auspicious sign in the world. It is all in the hands of man."

Li Chengqian's voice was deep and powerful, echoing in every corner of the court.

Fang Xuanling's slightly excited tone was completely different.

His words made the ministers look at each other in bewilderment. Many of them lowered their heads in thought, trying to guess the deep meaning of His Majesty.

Some ministers thought, "What does your Majesty mean? Doesn't he value this auspicious event? It seems your Majesty only likes practical things, not empty talk."

"Mr. Qi, explore coal mines across the country, establish mines, recruit people to work, and provide compensation tailored to local conditions."
