Traveling through Du He, Li Chengqian's rebellion begins

The reason why pork was considered a cheap meat throughout the dynasties was not only because of its smell, but also because of the poor processing and cooking methods.

Now that these two biggest drawbacks have been solved, will pork still be a cheap meat?

The domestic pigs raised by Du Gou using the castration method are not only larger in size, but also have excellent meat quality.

As long as the breeding and cooking methods are promoted, wealthy families and businessmen who see huge business opportunities will definitely raise them on a large scale.

The more fish are raised, the cheaper the price will be.

In the future, pork will become a delicious ingredient that ordinary people can afford.

Du Gou glanced at his second brother who seemed familiar yet unfamiliar to him, with a smile on his face, then he clasped his fists in the direction of the imperial palace and spoke.

"Everything we two brothers have done is to help your majesty solve problems and seek the well-being of the people of the world."

"As for leaving a name in history, it is not what my brother and I wish for."

Lu Chengqing clasped his fists in admiration and complimented, "Duke Lai is a man of high character!"

Du He curled his lips and said nothing more about the polite words from his elder brother and Lu Chengqing.

It's really boring to have a relaxing family dinner with so many false formalities.

Li Yi patted Du He's arm and said softly, "My husband, please write down the cooking methods later. I will present them to my father when I return to the palace for the family dinner tonight."

Although cooking a dish is not as elegant as poetry or song, it can improve people's appetite, which is also a great achievement.

Du He smiled and said, "Okay, I'll go write after dinner."

In addition to hosting Lu Chengqing's family for dinner at Duke Lai's Mansion today, Du He, Du Gou and Lu Chengqing also chatted in the study for more than an hour.

When Lu Chengqing left the Duke of Lai's Mansion with his wives, concubines and Lu Ziying, his face was full of smiles.

The alliance between the Lu family of Fanyang and the Duke of Lai's Mansion is of great benefit to both of them.

In the study of Duke Lai's mansion.

Du He wrote down all the pork cooking methods he knew according to his own cooking habits, and even drew a picture of the iron pan at the end.

Li Yi looked at the image of the iron pot and asked in confusion, "Husband, is this a pot? Why does it look like a big cover?"

Linglong also leaned over and asked, "How much iron material does it take to make the edge of the cauldron so high?"

"The rich and powerful can afford it, but ordinary people probably can't afford such a pot."

Like iron and salt, they were all under the control of the imperial court. Due to the backward mining and smelting technology, iron tools of this era were extremely scarce.

As the biggest warmongerer of the era, the Tang Dynasty provided all ironware to the army first to make weapons, armor, and bows and arrows.

Therefore, not much iron can flow into the hands of the public.

Du He said softly, "When the world is at peace, the court will release more iron materials, and the people will have the opportunity to buy them."

"If all else fails, we can capture a few more countries, plunder their weapons and ironware, and melt them down to make iron pots to sell."

"If we sell iron pans at a lower price, ordinary people will be able to afford them."

Hearing Du He's words, Li Yi and Linglong opened their mouths wide.

Linglong was speechless and said, "This...what's the difference between this and bandits?"

Du He gently tapped Linglong's head and said with a smile: "We, the Tang Army, are a righteous army. How can bandits be compared with us?"

"If you can save another country by destroying it, you are doing good deeds."

"It hurts." Linglong rubbed her head and muttered in dissatisfaction: "What are you talking about?"

They have destroyed other countries, and the bloodshed caused is unimaginable. How can they accumulate virtue and do good deeds?

She is not a three-year-old child and is not so easy to fool.

Du He ignored her and folded the rice paper with dried ink and handed it to Li Yi.

Li Yi glanced at the rice paper in his hand, and then said softly: "Husband, Linglong and I are going to the palace now, and we will live in the palace for the next few days."

"During the days when I'm not at home, you can't go out and do anything wrong with Cui Shenji and the others."

Although she had never been to Baihua Tower, Linglong had mentioned the four most beautiful courtesans who were good at playing the piano, chess, calligraphy and painting to her more than once.

It is said that the men in Chang'an City dreamed of marrying these four courtesans.

Looking at the pouting Li Yi, Du He said with a straight face: "Yier, do you still not trust your husband's character?"

"Besides, Cui Shenji, Wang Jingzhi and Xiao Kai have all returned to their hometowns. They will not be back until after the holiday."

The larger the family, the more importance it attaches to this traditional festival.

Every year on New Year’s Day, the family members living away from home would return home in glory and then hold a family meeting.

The Jingzhao Du family will also hold a clan meeting this year, but they did not invite the three Du He brothers.

Li Yi leaned her head on Du He's chest and said sweetly, "Husband, I believe in you."

When the master and servant left the study, Linglong made a face at Du He.

Prince Consort Du is extremely bad. Not only is he full of tricks, but he is also extremely capable. Few of the words he says are true.

Only the naive Princess would believe Prince Consort Du's lies.

"This damn girl."

Du He shook his head and cursed, then sat back at the desk.

He had to quickly write the meritorious work he promised to the third brother, as the third brother would have to return to Jiangzhou to take up his post in two days.

Numbers and calculation formulas such as addition, subtraction, multiplication and division are not difficult at all for Du He.

In less than an hour, he had sorted out all the things.

Then Du He went to the lobby and found Du Aitong who was chatting with Du Gou.

"The third child."

Du Aitong looked back, quickly stood up and said, "Second brother."

Du He walked over and whispered, "I have sorted out the things that will help you achieve merit. Now come with me to the study and I will teach you."

Arabic numerals are very simple for those who know them, but for someone like Du Aitong who has never been exposed to them, they are as difficult as climbing to the sky.

If I don't explain it to him several times, he may not figure it out even after a year or two if he figures it out on his own.

Du Aitong said with joy: "Second brother, let's go now!"

He was a promising young man and was very much concerned about his position as a doctor in the Ministry of Revenue.

"Brother, let's go to the study first."

The two men greeted Du Gou and then left the lobby.

In the study room.

Du Aitong looked at the strange symbols written on the rice paper and asked in confusion, "Second brother, what is this called?"

Du He smiled and said, "Let's call it the Zhenguan number."

"Zhenguan number?"

Du Aitong muttered to himself.

Although he didn't know how effective his second brother's innovative arithmetic symbols would be, based on his unconditional trust in his second brother, Du Aitong knew that it was definitely not an ordinary thing.

The Ministry of Revenue doctor is safe!

For two consecutive days, Du He and Du Aitong stayed in the study room all the time except for eating, drinking, defecating and urinating.

"I've finally finished teaching you!" Du He sighed, then picked up the teacup and took a sip of hot tea: "Old Third, you learn slowly first. If you don't understand something, I'll teach you when I come back from the expedition."

Du Aitong looked at the symbols on the rice paper and the densely written notes, and said with some confidence on his face.

"Brother, I have almost mastered it, and you even wrote down the notes. I will be able to do it after studying for a while."

In the Ming Dynasty, arithmetic was one of the subjects in the imperial examinations, and these children of powerful and wealthy people also received systematic arithmetic instruction.

My second brother is now just expressing the arithmetic symbols and methods using simpler characters.

The basic operation contents are similar.

Du He whispered, "You must keep the arithmetic information close to you and never leak it out."

"Second brother, I understand."

Du Aitong nodded seriously.
