In the heart of this Ming Empire, the top group of skilled craftsmen gathered in the world. They could get gifts that ordinary craftsmen could unimaginable, and they might be accidentally knocked into the abyss inadvertently, so everyone's attitude of working was extremely serious and responsible. In addition, there were three or five supervisions on their heads, and everyone's eyes widened, and no one dared to be careless.

Chongzhen got up at the fifth hour as usual, and the four palace maids immediately brought the purple gold basin that had been prepared to take care of the washing.

The four golden basins each have their own uses. A golden basin with a diameter of two feet is used for first washing hands, and a one-foot diameter is used for rinsing your mouth. A large golden basin with a diameter of four feet is used for washing your face. Finally, wash your hands again, and use one-foot-five inches in diameter. After washing, you will comb your hair.

After the emperor finished combing his hair, he had to worship him in his clothes and bow to heaven before he could change his casual clothes and prepare breakfast.

After Chongzhen changed his casual clothes, the palace maids handed over tea and snacks. Because the queen also came here to have dinner together today, and it took time to pass on the meal, and His Majesty the Emperor's stomach may be hungry, so he must first use snacks to fill his stomach.

Chongzhen used some tea and the palace servants who were in charge had almost set up breakfast. Just when the music sounded, the emperor went to the nave to prepare for breakfast. Although Chongzhen withdrew the music that he usually had for meals in order to save money, ritual music was also a kind of order in the palace, and even if he wanted to cut it all, he could not do it.

The queen is coming today, so there are two tables in the nave.

Chongzhen walked to his imperial case and saw the new book of the prince on the imperial case before he could even leave it. This was also the prince's privilege. Other words had to be submitted after the emperor had finished his meal and had to go to Wuying Hall or Wenhua Hall.

The emperor took a seat with his clothes and flipped through two pages casually, and his expression immediately became frozen on his face.

"Where is the prince?" Chongzhen asked out loud.

"Go back to the emperor," the eunuch of the Sili Prison who was accompanying him quickly stepped forward and said, "Your Highness the Crown Prince just went to Renshou Hall to pay tribute to Old Empress Zhang, and was left to eat."

"Call him." Chongzhen brought the book closer, and the fragrance of fresh ink made his nose itchy.

As the new work of the prince, this book "Theory of Epidemic Prevention" does not contain many pictures, and it is not as obscure as the previous "Physics" and "Chemistry". However, the book explains the source of this epidemic with a conclusive explanation and lists how to prevent and treat it one by one, which makes people convinced.

What really worried Chongzhen was that in the introduction to the beginning, the prince said that this epidemic caused a three-year epidemic in Europa three hundred years ago, and 25 million people died of this disease. According to the population of Europa at that time, almost one in every three people.

The Ming Dynasty began to flood and drought during the Tianqi period, and all kinds of disasters continued. If such a major epidemic occurred again... Chongzhen would almost be desperate.

Zhu Cixuan did not take the initiative to submit a letter to Chongzhen because Chongzhen had not issued a final order to let him go out to pacify the army. However, he was not surprised that Chongzhen could see the sample books so soon. This was also the rule in the palace. The Silijian would never print them in large quantities without even delivering the sample books to the emperor for review.

After saying goodbye to his aunt, Zhu Cilang stepped out of Renshou Hall, looked at the gloomy sky, and said to the little eunuch who came to pass the oral order: "Go and inform Johnson of the Imperial Heavenly Prison, and let him wait for the transmission."

The little eunuch dared not disobey his orders and hurriedly bowed and retreated.

Zhu Cixuan took his Eastern Palace guards and eunuchs to walk to the central hall of Qianqing Palace. Although the prince had the right to take a chariot, he preferred to walk, so that he could walk faster. When he reached the gate of Qianqing Palace, he happened to meet the queen's carriage, so he naturally had to go forward and salute and go in with his mother.

The Inner Palace Superintendent quickly prepared the prince's table and meals, and everything seemed to have been arranged long ago.

Zhu Cilang saw it and thought to himself: If the Ming Dynasty's administrative system could be as efficient and rigorous as the inner palace, there would be no chance for Li Zicheng and Zhang Xianzhong and others to stand out.

"Did Your Majesty sleep peacefully last night?" Zhu Cixuan greeted her.

"An." Chongzhen pointed to the meal case: "Sit down."

Zhu Cixuan sat at the bottom of his parents' table and piled up a table of various breakfasts in front of him. He had long wanted to change this buffet-style breakfast to a reservation dish, which would at least save ordinary meal costs. Although these foods would be given to other palace servants, it was not a waste, but the cost difference between the cakes eaten by the Tian family and the cakes eaten by ordinary palace servants was more than several times!

Because he had already asked his mother for good morning, Zhu Cixuan didn't have to ask Zhou Houan again. He looked at the "On Epidemic Prevention" in Chongzhen's hand and knew that he had guessed it for granted.

"Crown Prince, what you are talking about here is the current major epidemic in the capital?" Chongzhen asked.

"Father, the knot plague that is popular in the capital now is actually the Black Death disease, that is, the plague." Zhu Cixuan had already prepared abdomen on the way to come, and asked ten questions and answers: "The fleas carried by mice are spread to people. The patient will have knots in the groin, armpits, and neck. The disease will be in the second to eight days. Once the disease occurs, it will die within four hours, and is often accompanied by vomiting, diarrhea and other symptoms."

After hearing this, Zhou Hou, the chopsticks he had just raised were as heavy as a pound, and slapped them on the table, making him feel a little disgusting.

——This son knows everything, but he doesn’t know anything! You can’t wait until you finish breakfast before talking about these things!

Zhou Zhou took a deep breath.

Chongzhen no longer had any appetite and was not guilty of his guilt. He asked again: "The same is true for the Black Death that occurred in Europa?"

"Because many of the dead were black, the Europa called it the Black Death." Zhu Ciyang said: "As for the death population, the father can consult Johnson Chan from Germany."

"Go to spread Tang Ruowang." Chongzhen has always been decisive and decisive.

While waiting for the witness, Chongzhen asked about the way the plague spread and the observation of bacteria.

"Because of the microscope," Zhu Cilang said simply, "So my son knows that there are indeed Mount Tai, the smallest dust in this world, and even more tiny bacteria than dust."

Chongzhen nodded. He knew about the prince's small invention, and he himself had seen the veins of the plant with that simple microscope. At that time, the prince was still a very modest person, saying that it was based on the "Trace of Telescope" presented by Johnson Chan in the second year of Chongzhen.

In fact, even Joshua Chan did not expect that a six-year-old child could create a microscope.

Although this thing was invented by the Dutch forty years ago.

——No wonder the prince was so confident to go out to provide disaster relief, and he had already known himself and his enemy.

Chongzhen thought to himself.

But he didn't know that Zhu Ciyang would never really look for specimens of plague bacillus.

In this era without antibiotics, infection with the plague is basically a dead end. He is unwilling to take the risk of bringing this fierce infectious disease to himself for the welfare of all mankind. Moreover, although his microscope is extremely shocking, it is not enough to observe such tiny organisms as bacteria.
