Having said that, Zhu Di knows very well that this matter is definitely not fueled by any one person or party. Whether it is a civil servant or a military general, they are all the driving forces behind it.

The military generals promoted Zhu Zhanji, in order to flaunt Zhu Zhanji's martial heart and bring them closer to their grandson.

The purpose of Wenchen's propaganda of Zhu Zhanji was to remind all readers to be vigilant against Zhu Zhanji.

A grandson who dared to rush directly to the battlefield and kill forty-three people was not the ideal emperor of a civil servant.

Compared with his father Zhu Gaochi, the heir to the throne is a little too capable.

However, even if he knew this, Zhu Di could not punish anyone for this, because those civil servants could quickly change their positions and advertise that they promoted him because they admired Zhu Zhanji.

He turned his head and asked, "What is Taisun doing today?" ”

Li Qian bowed down and said: "The grandson didn't get up early today, and when he woke up, he ordered Young Eunuch Li to prepare contraceptive pills for the maid, presumably because of the internal strength and the kidney water has been solidified." ”

Zhu Di nodded and said, "This matter is very good, and it is time for the grandson to marry a wife." Edict ......"

Hearing this, Li Qian and the accompanying eunuchs immediately knelt down.

Zhu Di thought for a while and said: "Now that the victory is back, and give the people time to celebrate in April." With the inner palace supervisor, the seal and ribbon supervisor, and the governor of the prison, headed by Li Qian, he set up a guard of honor to select concubines, and went to various places to select concubines for the grandson. Since January of next year, the whole country will stop marrying, select 5,000 concubines for the grandson, allow the payment of round-trip expenses, and escort his parents to Beijing. ”

"Yes!"

Zhu Di turned his head and said to Zhang Guifei: "Now that the harem respects you, you also have to worry about this matter, check with the crown princess, and choose a good family affair for the grandson." ”

Zhang Guifei said with a smile: "The crown princess has been worrying about this matter for several years, and the concubine will help her make up for the shortcomings." ”

"It is better to choose a concubine who is docile and generous, but the grandson is very assertive, so you should also ask him more about his preferences."

Zhang Guifei couldn't help but smile and said: "Your Majesty has the world in mind, let's let us women worry about this kind of house affairs." ”

Zhu Di patted her hand and asked Li Qian again: "Has there been a schedule for today's grandson?" ”

Li Qian replied: "Today is resting, but the grandson can't be idle, and is ready to go to the coal mountain to investigate the charcoal burning. The governor has already made arrangements with Li Shaojian. However, early this morning, His Royal Highness King Zhao went to see His Royal Highness Taisun......"

He looked back at a little eunuch, and the other party immediately handed over a report, he looked at it, and handed it to Zhu Di.

Zhu Di took it and took a look, and the key points of today's conversation between Zhu Gaosui and Zhu Zhanji were recorded on the paper, so that Zhu Di could understand what Zhu Gaosui meant at a glance.

However, he is not like Zhu Gaosui, who can't figure out Zhu Zhanji's thoughts. Just thinking about it, he understood why Zhu Zhanji didn't care about the trade routes he controlled, and was willing to transfer some of the trade routes to Zhu Gaosui.

Because Zhu Zhanji doesn't care about this industry at all, what he cares about is the entire Ming Dynasty and the whole world.

A broad-minded Zhu Zhanji is extremely in line with Zhu Di's expectations. At the same time, he also looked down on the third son of the small family.

"You don't care about this matter, let Taisun handle it himself. When Wang Yan comes back, let him come and see me. ”

Wang Yan was the chief eunuch of the ceremonial eunuch, and before him, the ceremonial eunuch was only a slightly more important department among the twelve eunuchs, and the real department with the greatest power was the inner palace eunuch.

In addition to being responsible for all wood, stone, tile, earth, tower materials, eastward and westbound, paint, weddings, gunpowder, and rice and salt warehouses, construction warehouses, and imperial altar warehouses. He is in charge of the palace room, the construction of the mausoleum, the copper and tin makeup, the utensils and the ice cellar.

Another important duty is to oversee all eunuchs and all eunuch affairs, and the inner palace eunuch is a veritable "first agency" status, and in fact, it also occupies the position of managing and directing other eunuch institutions;

However, Zheng He, the chief eunuch of the inner palace, has always been famous all over the world and disdains to manage these flies and dogs, so the position of chief eunuch fell to the head of the celebrant eunuch.

It was also after Wang Yan that the celebrant really became the first eunuch.

Li Qian knew that when Zhu Di said this, he must have instructed the celebrant to cooperate with his grandson in maritime trade affairs.

At this time, Zhu Zhanji and his entourage were welcomed into the coal mountain by a group of officials and craftsmen of the Ministry of Industry.

Although today is the Mid-Autumn Festival, the coal kiln can not be turned off casually, even if it is the Mid-Autumn Festival, there are still many craftsmen busy here.

"Your Highness, please be careful, if you have something to do, why bother to come to this pickled place."

Zhu Zhanji covered his nose with a silk handkerchief and said with a smile: "Grandfather Huang handed over this matter to me, of course I have to be more dedicated." Although it is pickled here, so many craftsmen can tolerate it, and there is nothing I can't bear. ”

Stepping on the thick soot, Li Liang carefully followed behind, helping Zhu Zhanji carry the hem of his robe, for fear of staining Zhu Zhanji's new clothes.

Today's coal mountain is still a real coal mountain, except for the sludge from Sanhai that has been cleaned up, it is full of coal pulled from the West Mountain.

The coal burned the wall bricks for the construction of the Yanwang Mansion, and the waste residue was piled up on the foundation of the coal mountain.

On the north side of the coal mountain, there is a row of eight brick kilns, six of which are brick-burning and two are charcoal-burning.

In this era, there is no environmental protection thinking at all, people are struggling to fill their stomachs, and no one has the leisure to care about environmental issues.

Therefore, the environment here is indeed a bit bad, and those coal workers and brick workers are dirty and can't see their original appearance.

Even if Zhu Zhanji had the idea of having fun with the people, he couldn't stand the soot in the sky, so he could only use a handkerchief to plug his nose, at least he could filter it.

Zhu Zhanji's purpose is to see how the technology of Daming charcoal burning is developing and whether the technology can be graded.

If it can be graded, the best technology will be retained, and only the next level of technology will be delivered to the Uliangha.

But everything in front of him disappointed Zhu Zhanji, even if he was the charcoal burning master with the best skills, he only relied on experience to bake coke.

This is also a common problem for most technical workers in the Ming Dynasty, who don't know why.

The general environment is like this, and Zhu Zhanji has no choice.

During the Han Dynasty, the discourse power occupied by Confucianism, and the four levels of Shinong, industry and commerce had been completely solidified.

The craftsmen were inferior to the peasants, they could only be regarded as inferior people, and they were not as rich as the merchants, so they themselves looked down on themselves.

The whole society looks down on these engaged in technology, and they regard it more as a helpless fate. There is no upward path, and they have never thought of achieving social status through technological innovation.

Unless it's a true idealist.

These coke masters, they know how to turn coal into charcoal after it is baked at high temperatures, but if you ask them to say why, they don't know.

Everything is handed down from our ancestors, and they only follow the guidance of experience, and never consider why coal is more resistant to burning after being roasted at high temperatures, and the temperature is higher.

In later generations, high-temperature coking was only a basic industry, and coke was also divided into three categories: metallurgical coke, foundry coke and chemical coke.

But in this era, it is simply impossible to have such an industrial base. The only thing they have at their disposal is to simply remove the impurities from the coal and carry out simple coal coking.

Zhu Zhanji had never been exposed to these basic industrial models in his previous life, even if it was an open-hearth furnace and blast furnace for steelmaking, he had seen it with his own eyes, but he had never been in contact with coking.

Therefore, he can't give any hints or suggestions at all, and can only use the current technology.

After a delay here for an hour, those craftsmen trembled one by one in front of Zhu Zhanji, eager to take out their hearts.

But none of them were able to solve the grading problem raised by Zhu Zhanji.

In this way, in terms of coking, the Uliangha people will not be stuck.

However, just because you can't control it technically doesn't mean you can't control it economically.

As long as Da Ming has the pricing power and only leaves a small profit for the Uliangha people, they will always have to work for Da Ming.

Zhu Zhanji left the coal mountain with some disappointment, and before leaving, he looked back at the now inconspicuous coal mountain.

Without the construction of the Forbidden City, the scale of this place would not have expanded, and several Haizi had not cleaned up the silt, so I don't know if there would be Jingshan in the future.

However, if the Ming Dynasty solves the grassland problem, there is no need to build Beiping at all, and it will become the mainland, and the military status will be greatly reduced.

As soon as he got out of the coal mountain, he met Li Qian who was coming to him. Li Qian smiled, and when there were still more than ten meters away, he hugged his fists and congratulated: "Old slave, congratulations to Your Highness, Your Majesty has issued an order to choose a concubine for Your Highness." ”

Zhu Zhanji has turned sixteen years old, and if it weren't for this Northern Expedition, the election of a concubine would have been put on the agenda as soon as his birthday passed, so he was not the slightest surprised. "Presumably, Eunuch Li is in charge of the great etiquette for choosing a concubine this time, and I hope that Eunuch Li will choose a few more beauties for me."

Li Qian said with a smile: "The old slave came to His Highness to ask His Highness's preferences, so that we can pay more attention to it when we pick people." ”

According to Zhu Yuanzhang's Daming law, the selection of concubines by the prince and grandson is basically a dial.

However, Zhu Di only has three adult sons, all of whom are married. Of the grandchildren, in addition to Zhu Zhanji, the eldest Zhu Zhanji is only twelve years old, and he is not yet the age to choose a concubine, so this concubine selection is basically to serve Zhu Zhanji alone.

The selection of concubines is divided into eight levels, the first level is the sea selection, 5,000 people are selected nationwide, and the imperial court pays the travel expenses to the capital for the second round of selection.

In the second and third rounds of selection, the eunuchs chose a large venue and lined up the girls in a row of 100 girls, sorted by age. After some inspection, the girls who were too tall, short, fat and thin were eliminated, and each person's facial features, hair, skin, timbre, and demeanor were carefully examined, and as long as there was one irregularity, they were eliminated.

The remaining about 2,000 people will be selected for the fourth round. In this round, the eunuchs will not only use a ruler to carefully measure the girl's hands and feet, but also examine the girl's gait and charm. This step will eliminate another thousand young girls. In the end, the 1,000 beauties left behind were summoned to the palace to continue to participate in the selection. And the mission of the eunuchs has come to an end, followed by the selection of palace maids and concubines, including the emperor and princes.
