At noon one day, Zhu Di reviewed the recital for a night and a half, and had a migraine, feeling very dizzy in his head, as if he had weighed a thousand weights.

After reviewing the last book of music accumulated in the past few days, Zhu Di stretched his waist and was about to sleep to relieve this feeling now.

In fact, this kind of migraine was often experienced by Zhu Di in his previous life, and he also asked the opinion of the imperial doctor, which is very simple, it is caused by irregular work and rest and staying up too late.

Zhu Di was a diligent madman in his last life, the kind that boasted that he only had a father before and no one after him, and this life naturally continued his consistent style.

But compared with the previous life, Zhu Di, who is now young again, also has many young people who are beneficial, and it is a way to live for two consecutive lives, which is too tiring.

Thanks to this strong physique, Zhu Di is now full of energy no matter what he does.

Whether it is training to prepare for war, or riding a horse to shoot and hunting, or lingering with the concubines in the harem for a few days, it is no longer the same as in the previous life, and the heart is more than enough.

Although Zhu Qiyu was called cowardly by Zhu Zhanji, it was only limited to his own character, and his body was much stronger than the Ming God of War, who only knew how to pamper all day long.

Let's put it this way, Zhu Qiyu's body is like a big unpolluted water tank, very clear, whatever color Zhu Di wants to dye him in, it will be whatever color it is.

When you are healthy, you naturally have to do many things that you wanted to do in your previous life but didn't have time to do.

For example, in the past few days, due to the matter of the old national uncle Wang Quan, the relationship between Zhu Di and Wang Meilin has heated up rapidly, and Zhu Di has also begun to really regard this woman as his virtuous helper.

The mentality has changed, and the number of visits to Kunning Palace has increased.

But Zhu Di still couldn't let go of the mountains of notes, which caused his body to seem to be hollowed out in the recent month, and the excessive sexual affairs and the handling of state affairs day and night made Zhu Di feel physically tired.

"It's time to take a break." Zhu Di leaned on the throne and commanded, "I won't watch the music today, unless there is an emergency, don't disturb my rest."

"Yes." Wang Zhi, the little eunuch who was standing outside, agreed.

Zhu Di noticed his discomfort, and felt that this previously shrewd little gelding had been very strange recently, and said with a smile: "What's wrong with you lately?"

Wang Zhi was stunned for a moment, but he didn't expect the emperor to see it, and hurriedly said, "Your Majesty, the slave is reluctant to leave Your Majesty, and you can only learn things by following Your Majesty!"

Zhu Di smiled, he didn't want to say, and there was no need to ask more.

Zhu Di is still very relieved about Wang Zhi, or he would not have stayed by his side.

Zhu Di naturally could see that this little eunuch's heart was not as simple as it appeared, but he was not a threat to himself, so he turned a blind eye.

This Wang Zhi is only sixteen years old this year, and he was originally just a little eunuch who couldn't get along with the center of power, but because of his cleverness and intelligence, he was exceptionally left by Zhu Di to serve in the Qianqing Palace.

For a long time, although he was only a little eunuch, not even half a brand, but because he was close to the water, his status in the inner court was rising.

Even Cao Jixiang, the eunuch with the palm print of the superintendent, was doubly hostile to Wang Zhi.

….

Sinister crotches like Cao Jixiang abound in the inner court, and they will not think that they have not seized the opportunity, but will only feel that Wang Zhi, a little eunuch, is too good at flattery.

Wang Zhi has also noticed some clues recently, in this inner court, there are three or two irrelevant palace people who die or disappear on weekdays, which is really an ordinary thing.

Therefore, these days, Wang Zhi is even more of a servant to Zhu Di before and after the saddle, except for eating, sleeping and going to the toilet, he almost does not leave the Qianqing Palace for half a step.

Inside and outside the Qianqing Palace is the important place where the four guards of the government army and the guards with knives are sanitation, and the eunuch Wang Cheng of the commander of the East Factory prohibits it, and the battles in the inner court almost end here.

Now although Wang Cheng is hostile to Wenchen in the Outer Dynasty because of his control of the East Factory, he is a well-deserved chief in the Inner Court, and even the old crotch of the orthodox period of the Celebrant Supervisor Yin Xing'an, he does not dare to oppose it.

"Squint for a while, I'm too sleepy..."

Zhu Di muttered a few times, and soon fell into a deep sleep, and not long after, there was a sound of footsteps outside the door, and he talked to Wang Zhi for a few words.

The man also seemed to have given up trying to break in, but because he was too anxious, he turned left and right in the Qianqing Palace, waking up Zhu Di, who was already very sleepy.

"Who is it?"

Hearing the inquiry, both of them outside the door were obviously shocked.

The two ran in one after another, but saw that Wang Zhi was followed by a clerical officer wearing the official uniform of the Tiangong Bureau, and the clerical officer came in and said happily.

"The minister didn't want to disturb Your Majesty, but Your Majesty, this is a great joy for the world!"

"Zheng Xu, the chief craftsman of my Tiangong Bureau, reproduced the Qimu Huaiwen steel filling method that was lost hundreds of years ago, using two quenching mediums, animal urine and grease, to cool and expand the use of quenching medium!"

"What do you mean?" Zhu Di was a little confused when he heard this, and his expression was dazed.

The clerk also realized that the emperor might not understand these professional terms, so he hurriedly said, "The minister said that my Tiangong Bureau has developed a quenching method for high-quality steel!"

"From now on, I have high-quality steel that can be used to forge knives, guns, and armor!"

Zhu Di naturally understands the importance of this to the Ming army, if high-quality steel can be mass-produced, then the Ming can use high-quality steel to strengthen the blades and armor used by the current officers and soldiers.

It can make the blade sharper, it can also make the armor tougher, and in addition, many key parts of the firearm can also be replaced with high-quality steel!

Although he doesn't know how to make steel, Zhu Di still understands this common sense.

"Really! Take me with you!"

The clerk obviously didn't have anything to say, but Zhu Di couldn't care about anything else, jumped up from the throne, took three or two guards with knives and went straight to the Tiangong Bureau factory on the outskirts of Beijing.

Zhu Di, who was in a hurry, suddenly forgot the faint pain in his head, and he didn't notice the resentful eyes of Wang Zhi behind him.

Zhu Di took the war horse from Nanyuan that followed him out of the capital and fought against Wara, flicked the whip, and galloped out of Chengtianmen from the official road and went straight to Andingmen.

Everywhere they passed, the people stopped to watch and were amazed.

Soon, Zhu Di came to the outskirts of Beijing with a guard with a knife, and Zheng Xu, the chief craftsman of the Tiangong Bureau, was waiting here early, and hurriedly saluted: "Your Majesty is here!"

"Excuse me, tell me how you made good steel?" Zhu Di waved his hand again and again, walking back and forth beside the blast furnace, looking very excited.

Zheng Xu saw that the emperor attached great importance to this, and instantly felt that the day and night study during this period of time had not been in vain, and the craftsmen of the Tiangong Bureau also nodded at each other, very pleased.

"Your Majesty, please look!"

"Chen used these two things taken from the folk to reproduce the medium method of smelting high-quality steel by Qimu Huaiwen hundreds of years ago, and created the high-quality steel of my Ming Dynasty!"

"But Your Majesty, this is just a technology that existed hundreds of years ago, and the minister reproduced it in detail and told the world that His Majesty was not wrong to set up the Heavenly Works Bureau! This is just the beginning!"

"Yes, yes!" Zhu Di turned around, looked at the craftsmen who gathered around, and said, "You all have merit, pass on the edict and let the Ministry of Industry give them merit!"
