Imperial Palace, Wuying Palace.

During the period when Zhu Di was making money in the grassland, Zhu Yunwen was not idle.

He not only designed the latest version of the Daming treasure banknote, but also improved the papermaking process, and even corrected the gunpowder ratio.

Now the strength of Jingying has improved a lot compared to before.

As long as the Ganguo steelmaking method is successful, Daming will enter a new era.

Of course, there is also Li Jinglong's credit in this.

Since Li Jinglong received the recital from Zhu Yunwen, he worked day and night, lasted two months, and finally found a new gold mine.

Because of these gold mines, the Ming court began to issue a new round of Ming treasure banknotes.

In this way, the Ming court will not stop developing in a short period of time because of the problem of money.

At this time, Zhu Yunwen was studying the firearms drawings of the Ming Dynasty.

If he wants to improve the current firearms, he must understand the firearms technology of the Ming Dynasty, otherwise the new technology will be passed on to the craftsmen of the Ming Dynasty, and they will not be able to start.

"It really can't be done overnight!"

Zhu Yunwen couldn't help but sigh after reading all the firearms drawings.

From the musket to the arquebus, to the flintlock pistol, it has gone through hundreds of years.

The development of these hundreds of years is not only a gap in technology, but also a gap in materials.

Even if he knew the process of making a flintlock pistol, with Da Ming's current ability, he couldn't make it.

Therefore, the only way to do this was to change from a musket to an arquebus.

The principle of the arquebus is very simple, mainly using dry hemp rope to soak potassium nitrate, ignite it in a smoldering state, and then through the machine bracket, pull the arquebus to burn the gunpowder in the barrel, and launch it.

The difficulty is not the production of the bracket, but the extraction of potassium nitrate.

But for Zhu Yunwen, this is not a difficult point at all, because he was a scholar in his last life, and he doesn't know how many ways to extract potassium nitrate.

wrote a simple and effective extraction method, and Zhu Yunwen asked Wang Zhong to prepare the materials.

At this time, He Chong was taking Xie Jin to Wuying Hall to meet Zhu Yunwen.

"Your Majesty, Lord Xie is here." He Chong reminded Zhu Yunwen.

Zhu Yunwen looked up at Xie Jin, and found that his nose was blue and his face was swollen, and he couldn't help but be stunned: "Xie Qing, what's wrong?" ”

"Your Majesty——!"

Xie Jin heard Zhu Yunwen's inquiry, and without saying a word, he knelt down directly, crying bitterly.

The corners of Zhu Yunwen's mouth twitched slightly, and he waved his hand at He Chong, who retreated in a witty manner.

The name of Xie Jin can be said to be indestructible.

This rare genius of the Ming Dynasty plays a pivotal role in the progress of the Ming Dynasty.

Among them, the most talked-about is the "Yongle Canon" compiled by him.

Xie Jin was born in the second year of Hongwu, at the age of five can memorize poems, at the age of seven can write articles, at the age of twelve read through the "Four Books" and "Five Classics", at the age of eighteen in the middle of the Yuan, at the age of nineteen Wuchen Kejinshi three top tenth, given the same Jinshi, awarded the Jishi.

Zhu Yuanzhang admired Xie Jin's talent, stayed in the former imperial counselor, and was promoted to bachelor of Hanlin.

Nineteen-year-old Xie Jin is already standing at the height of countless people.

Think about it, what is the nineteen-year-old doing? It's just the second place in the province!

Zhu Yunwen shook his head with a wry smile, then came to Xie Jin's side, stretched out his hand to help him up, and said seriously: "What is Xie Qing doing?" Crying is a big sin! ”

"Huh?"

When Xie Jin heard Zhu Yunwen's words, he was suddenly startled, quickly wiped away his tears, and said aggrievedly: "Your Majesty, the minister heard that you have ascended the throne, and I have come to congratulate you..."

"But that Zhu Gaosui wants to take his ministers to the edict prison for trial....."

As he spoke, tears flowed down again.

Seeing this, Zhu Yunwen sighed again, and said in his heart that poor people must have something to hate.

This Xie Jin is young and in a high position, lacks social tempering, is arrogant, and always feels that the fault is someone else's.

Therefore, in the Lao Zhu Dynasty, today he accused this imperial history of not doing personnel, and tomorrow he said that the military department was negligent in his duties, and the day after tomorrow he would write a twist and turn to compete with Lao Zhu.

didn't mix up the officials for two years, and offended a lot of people.

Later, some people really couldn't stand it, so they impeached him with Lao Zhu.

Although Lao Zhu cherished his talents, he also felt that this guy needed to be sharpened, so he asked him to go to Jiangxi for inspection.

As a result, not long after he ran to Jiangxi, he began to die again.

Lao Zhu was really helpless, so he had to send him home, study behind closed doors, and agreed to use him again after ten years.

As a result, Xie Jin's mentality collapsed.

He felt that he had only told a few words of truth, how could he be punished like this?

Isn't being an official a scholar just to uphold justice for the people of the world? Isn't it just to serve the country?

Those who don't do their jobs all day long, slip around and blame each other when they encounter problems, and even grasp the power and don't care about the people's livelihood, how can they occupy a high position?

As a clean official who serves the country and the people, why is he treated like this?

It's not fair!

On the day of the dismissal, Xie Jin was very depressed.

He misses the prosperity of the capital, the importance of the emperor, the admiration of everyone, and even the wine of Chunhualou.

But he didn't dare to disobey the emperor's order.

I can only count the days at home while reading.

After seven years in this way, until Lao Zhu died, he ran to the capital on the grounds of running for funeral, hoping to make a comeback.

But when he arrived in the capital with his front foot, he was targeted by the Jinyi guard with his back foot.

That's why Zhu Gaosui led people to arrest him.

And Zhu Yunwen, who learned the news of Xie Jin's entry into Beijing, also notified Jinyiwei to bring him to see him as soon as possible.

So, Xie Jin appeared in front of Zhu Yunwen like this.

Zhu Yunwen took a closer look at Xie Jin, and found that this guy was short, thin, mediocre, and not at all as graceful as a talented person should be.

However, Zhu Yunwen still understands the truth that people can't look good.

I saw him smile and said: "Gao Sui is young and reckless, I will educate him, but Xie Qing came to Beijing rashly, it is indeed a little inappropriate." ”

"Back to Your Majesty, the minister came to Beijing rashly, not intentionally to destroy Emperor Gao's ten-year covenant, but Emperor Gao treated his ministers like sons and nephews, and the minister was grateful for Emperor Gao's kindness. Xie Jin replied earnestly.

Zhu Yunwen was a little funny in his heart.

At the beginning, Zhu Yuanzhang did have a 'father and son' theory with Xie Jin, so there was the famous "Da Ku Xifeng Affair" in history.

But Zhu Yunwen re-used Xie Jin for other reasons.

I only heard him smile and said, "Since Xie Qing is back, let's go to the Hanlin Academy to be a waiter!" ”

"Thank you, Your Majesty, Longen!"

Xie Jin's heart was shocked, and he hurriedly kowtowed to Zhu Yunwen to thank him.

Zhu Yunwen waved his hand: "Okay, let's eat together first, I'm hungry, I'll talk about it later." ”

Xie Jin originally planned to leave after thanking him, but he didn't expect Zhu Yunwen to invite him to dine together, and he couldn't help but be excited.

It was simply unexpected.

The heart said, could it be that before Emperor Gao's death, he asked His Majesty to reuse himself?

If that's the case, then you have to take advantage of the opportunity!

With full joy, Xie Jin followed Zhu Yunwen to a side hall.

I saw that in the middle of the side hall, there was a table with a strange shape, and in the middle of the table, there was a steaming copper pot.

Around the copper pot, there are a variety of dishes that look delicious.

"Your Majesty, what is this?"

Xie Jin looked at Zhu Yunwen curiously.

Zhu Yunwen smiled and didn't say anything, just raised his hand to signal him to take a seat.

Soon, a hot pot that is about to go down in history will start soon.
