After dealing with the affairs in the court, Zhu Cihong first went to Kunning Palace and pleaded guilty to Queen Zhou about the death of the national abbot.

Although Queen Zhou was not angry, she was not too embarrassed by Zhu Cihong, what her mother's family did made her feel cold, and made her feel embarrassed, Queen Zhou said that she would no longer care about the affairs of the Zhou family.

Then Zhu Cihong went to visit the old lady Liu and Empress Zhang, and went to Nanjing, I don't know how many years it will take to come back, and the elders in the palace who watched him grow up don't know if they can see each other again, especially the old lady Liu, who is in her eighties.

In the Qianqing Palace, the sleeping Chongzhen suddenly woke up, obviously having a nightmare.

When he opened his eyes and saw Zhu Cihong in front of him, his whole body suddenly trembled, and he said angrily: "You still dare to come to see me? I'm really blind, and I've set up you as a disloyal and unfilial thing! ”

Zhu Cihong sat on the embroidered stool and said peacefully: "Father, what are these words, if the Ming Dynasty is free of disasters and difficulties, and it is as strong as the Emperor Chengzu period, the sons and daughters do not need to be so deliberate to grasp the power and save the Ming Dynasty." ”

Chongzhen was stunned for a moment, and said angrily: "Save Daming? What a high-sounding reason, so why don't you discuss it with me? Such a bold act! ”

Zhu Cihong's gaze was like a tangible, piercing straight into Chongzhen's heart, and said: "The son wants to discuss everything with his father, but the father always likes to go his own way, you are the son of heaven, you are a man of heaven, you can't change you, you can only change yourself." ”

Chongzhen sneered: "Clever words! Aren't you afraid of stirring up the rebellion of the landlords, gentry, merchants, nobles and other classes of the Ming Dynasty? ”

Zhu Cihong shook his head and said: "Erchen has read few books, and he doesn't understand those messy bends, so he can only use the simplest way to solve the problem." ”

"Say no more!" Chongzhen's face was ugly, panting, and he waved his hand: "You won!" ”

Zhu Cihong sighed, it is really the father who does not know the son, and the son who does not know the father.

He said: "Erchen said a few years ago that the emperor has no rebellious prince, and everything Erchen does only wants to change his father!" ”

After saying this, Zhu Cihong's face was not red and his heart was not beating, he looked calm, obviously his face was thicker after years of tempering.

Chongzhen weighed it blankly for a long time, and his eyes stared at Zhu Cihong's face for a long time, and finally let out a long sigh, even if he was not convinced, he was powerless to change.

However, his current situation seems to be better than Li Yuan, at least after the prince went to Nanjing to supervise the country, the north of the Yangtze River in the Ming Dynasty still has the final say, and he is the nominal son of the Great Tomorrow, and the Ming Dynasty has never fallen into the hands of foreign surnames......

Chongzhen tidied up his clothes, and suddenly said: "When will the 50 million taels of silver promised to me be delivered!" ”

Zhu Cihong was stunned for a moment, and there was a black line in his head, and this father is still thinking about this silver.

Chongzhen glanced at him and said, "What, you regretted it?" ”

Zhu Cihong said: "Give and give, I just hope that my father can leisurely order flowers, don't feed those corrupt officials and corrupt officials." ”

Chongzhen sneered and said: "You just take care of yourself, Jiangnan is Donglin's lair, they can't stand up when they are suppressed by me in Beijing, if you go to Jiangnan to support them, it's okay, if you still have tough methods, I'm afraid that I won't know how to die when the time comes." ”

How could Zhu Cihong not know that the Donglin Party was a bureaucratic class political group dominated by Jiangnan scholars, and its power was intertwined and very difficult to manage.

Before leaving, Chongzhen didn't forget to light the cannon and said: "You attach importance to the martial arts class, be careful that one day you can't control that group of arrogant soldiers, think about the blue jade of the Hongwu Dynasty." ”

Zhu Cihong said with a smile: "This doesn't have to worry about the father, after the sons go south, the three general soldiers who are secretly ordered by the father will be returned." ”

Wang Tingchen and the other three general soldiers all made great contributions in the battle of Liaodong, and their evaluation in history was also good, and Zhu Cihong couldn't bear to get rid of them.

As for Chongzhen's worry about the martial arts class to become bigger, it is even more impossible, the Tianwu Army has undergone several military reforms, and the power has long been in the hands of Zhu Cihong, he has completely separated the right to train troops, the right to command troops and the right to transfer troops, the military tun department is responsible for training, military generals commanding troops, and the military aircraft department is responsible for coordinating the transfer of troops, no matter who wants to transfer troops, they can only go through Zhu Cihong and the military aircraft department.

Now Huang Degong and Yang Yufan are still in Huguang and Fengyang, even if Sun Yingyuan and Zhou Yuji have the highest positions in the Tianwu Army, they can only mobilize the divisions directly under them in private, and the only one who can not transfer troops through the Military Aircraft Department is Zhu Cihong.

Chongzhen waved his hand and asked him to leave, Zhu Cihong didn't bother to talk nonsense with him, patted his ass and left.

Soon after Zhu Cihong left the palace, Chongzhen approved the will drawn up by the cabinet, and officially ordered the crown prince Zhu Cihong to go to Nanjing to supervise the country.

In front of the palace of King Xin, Sun Yingyuan and Zhou Yuji knelt under the steps of the gate, and had been kneeling there since they came back from the end of the court, pleading to Zhu Cihong.

The crown prince's guard of honor passed by the two, and Zhu Cihong went straight into the palace and ignored them.

Although Sun Yingyuan and Zhou Yuji were thoughtful, they had already committed Zhu Cihong's taboo by not saying hello to Zhu Cihong before they acted.

Zhu Cihong wants them to have a long memory, no matter how much credit they have, when they do things under him, they must understand the rules, and they can't make decisions for their families.

After returning to the palace, Zhu Cihong successively summoned several brigade commanders of the Tianwu Army and asked them to arrange for the various departments to go south.

At night, Xu Sheng came to plead: "Your Highness, Jing Wubo and Ding Xibo have been kneeling outside for four hours, and the sky is overcast and about to rain, so you can spare them this time." ”

Zhu Cihong looked intently at the "Treasure of Arithmetic" in his hand and said, "I didn't punish them, they can go home at any time if they want to leave." ”

Xu Sheng was about to say something more, but he only heard Zhu Cihong say: "If you have nothing to do, you can learn arithmetic with this palace, this "Treasure of Arithmetic" written by Wang Wensu is a divine book!" ”

Xu Sheng muttered: "Arithmetic and skillful, what is there to learn." ”

Zhu Cihong said: "This palace replied to you with the words of Master Wang Wensu: The ancient sages are still important, but how can ordinary people today ignore the end of the six arts?" ”

As he spoke, he threw a copy of "Sun Tzu's Arithmetic" on the table to Xu Sheng, and said: "You learn more arithmetic to develop IQ, go and solve the problem of chickens and rabbits in the same cage on page 25 above, and if you can't solve it, you are not allowed to sleep!" ”

Xu Sheng suddenly had two heads and two big, holding a book and studying the problem of chickens and rabbits in the same cage.

Zhu Cihong looked at the book "Treasure of Arithmetic" again, this book is really a divine book, which not only introduces higher-order equations and multivariate higher-order equations, but also the world's first concept of derivatives, and the algorithm of using derivatives to solve higher-order equations, 140 years ahead of Newton and Leibniz.

All show that algebra is lost, decline, the lack of theoretical mathematics achievements led to the stagnation of the development of science in the Ming Dynasty, the Ming Dynasty mathematics master Wang Wensu's "Treasure of Arithmetic" smacked the face of those experts in later generations, the mathematics recorded in this book is not only high-end, even the solution of the unary high-order equation and the Tianyuan technique, the quaternion, etc., are rumored to be lost in the Ming Dynasty The mathematics are recorded in it.

The Treasure of Arithmetic not only represents the highest level of mathematics in the Ming Dynasty, but also represents the highest level of mathematics in the world during the same period, and even modern mathematics in later generations also used many of its algorithms.

With a deeper and deeper understanding of this era, Zhu Cihong found that the Ming Dynasty was really an underestimated dynasty, especially in the development of economy, culture, and science and technology, which was buried too much.
