Daming: Grandpa Emperor, please get up and sit on my throne!

"You are aware that His Majesty has been in a bad mood recently and prefers to be alone. I have tried to comfort him, but it is of no use."

"But... that kind of thing always takes some time. I will advise Your Majesty from time to time. Your Highness, please rest assured." Lu Wei was already very familiar with covering up such things for Zhu Yuanzhang.

However, Zhu Di remained expressionless, showing no sign of rising. "If it had only been three or five days, it would have been fine, but it's been a long time now. A father can be willful, but a son cannot be unfilial and sit idly by while his father grieves."

It is only natural for a son to see his father, and he has no shortage of explanations on this point.

Seeing that he couldn't persuade her, Lu Wei had to give up.

Back in the main house, Zhu Yuanzhang probably heard what was happening outside and stood up from the armchair.

Lu Wei looked at Zhu Yuanzhang with an embarrassed expression: "Your Majesty, His Royal Highness the Prince of Yan is kneeling in front of the door and refuses to get up. What should we do?" He could handle other matters, but since he was Zhu Yuanzhang's own son and a prince, he could only ask for instructions.

Zhu Yuanzhang's eyes fell on the door closed by Lu Wei.

Lift your foot and take a step forward.

He and Lu Wei did not notice Qiu Fu's whereabouts, so naturally they had no idea what kind of mentality Zhu Di had as he knelt in front of him.

Besides, he had just lost his eldest son, and not long before that, his second and third sons as well. How could he not be a little soft-hearted towards Zhu Di, the fourth son? Plus, Zhu Di was also a good actor...

Of course, Zhu Yuanzhang still felt distressed and shaken.

But then he took it back, sighed secretly, and said in a low voice: "The fourth brother... is indeed a good boy, but we still can't see him now." Otherwise, he would not have gone to such great lengths to avoid Zhu Di's eyes and ears.

After a pause, he sat down again and said in a low voice, "Open this window a little." The window was opened a little, and he could catch a glimpse of the situation outside from his position.

Although he was determined not to go out, as Zhu Di had expected, the only soft heart of Emperor Hongwu was reserved for his sons.

Watching Lu Wei open the window, Zhu Yuanzhang frowned and shouted, "If he wants to kneel, let him kneel!"

Outside the main house, Zhu Di heard Zhu Yuanzhang's voice and his heart sank slightly. He looked up and saw that a window in the main house moved and opened a crack. His heart beat faster.

There was an imperceptible curve at the corner of his mouth.

His eyes became more determined.

The snow falling from the gloomy sky seemed endless, piling up into a layer on his body, and even making Zhu Di's nose a little red from the cold.

……

The words are divided into two parts.

Yingtian Prefecture, Forbidden City.

In the dead of winter, it was snowing in Peking and Yingtian Prefecture, but the snow was not falling as heavily. The humidity in the south made the snow even colder. The entire Forbidden City was covered in silver, filled with solemnity and tranquility.

It was warm inside the Qianqing Palace.

Several charcoal braziers were burning, and the windows on both sides were half opened for ventilation, making the air less stuffy.

Zhu Yunhuan returned to the front yard from the backyard with a satisfied smile on his face: "The first batch of sweet potatoes are stronger, and the second batch of seedlings are growing faster and better."

Ma Sanbao brushed the snow off Zhu Yunhuan's body, took off his cloak and put it aside, with a warm smile on his face: "This is only a small part of the backyard. The one in the imperial garden is just as thriving. When spring comes, Your Majesty may have a huge harvest!"

"Although it is snowing this winter, my heart is always warm. The people are even warmer, with good clothes to wear and good charcoal fire to keep warm. Who could have imagined that we would have such a day? Auspicious snow indicates a good harvest. We are getting more and more hopeful about the Ming Dynasty next year." Ma Sanbao said.

These words really touched Zhu Yunhuan's heart.

My mood suddenly became much better.

Although he knew that there would be a lot of things waiting for him in the future, this period was the most relaxing time since he ascended the throne. Before that, he was busy waiting for the sweet potatoes to grow, waiting for cheap cloth to be produced, and waiting for anthracite to be produced and sent to major provinces, prefectures, states, and counties in the Ming Dynasty.

I also have to worry and plan from time to time, so I can say I never relax.

Now that everything has been completed, the turmoil in Yingtian Prefecture has calmed down, and people are now more at peace.

"By the way, how is the high-alumina bauxite issue going on with Song Zhong?" Zhu Yunheng looked at Ma Sanbao and asked casually.

Being in this position, as long as the Ming Dynasty has not been completely put under control, he will not forget to always be prepared for danger.

Of course, he also considered what Zhu Yuanzhang considered.

However, he had considered the threat posed by the Huaixi nobles as early as the day Zhu Yuanzhang passed away, so he had been making preparations.

Now everything else is settled.

Of course, the issue of steel production had to be put on the agenda - one of the four major industrial raw materials, it was indispensable for the improvement of guns and artillery, the production of weapons, and the subsequent steam engines required by the Huaixi nobles.

Now the water-powered spinning machine and the flying shuttle loom are almost ready, and popular science education has also begun to be spread to the Ming Dynasty to provide preventive measures. This is the first step in promoting the industrial revolution.

If they wanted to prepare for the second phase of factories, trains, ships... and even the Age of Exploration, they had to first develop the steam engine - and the prerequisite for this was steel!
