Daming Yinghua

On the way back to Wenhua Hall from the Three Great Halls, Wang An didn't talk to Zheng Haizhu.

The little maids and little firemen met along the way, when they saw Wang An, they were more respectful and timid than when they faced the eunuch Xue.

When he was approaching the imperial pharmacy, a pink figure, like a burst of peach petals blown up by the wind, came towards him.

"Ah, Eunuch Wang, is this Master Zheng who is going to teach my brother?"

The people in the pink group stood still in front of Wang An and asked softly.

"Why are you here?" Wang An's rhetorical question was cool, and he didn't stop his steps.

"Oh, my brothers have been waiting in the Wenhua Palace for almost two sticks of incense, and the master still hasn't come, so I made a fuss for the slaves to come out and ask."

As Ke Yinyue said, she quickly looked at Zheng Haizhu behind Wang An.

Zheng Haizhu followed the other party's gaze without showing any respect.

There is no rule for court officials to greet maids in the palace.

But Zheng Haizhu judged sensitively in her heart, this is the famous nanny in history...

Keshi should be about thirty years old, and she does look like a beauty, with picturesque features and a hint of style.

Relying on intuition, Zheng Haizhu caught Ke Shi's glance, and suddenly his sharpness faded, and a faint sense of relief appeared instead.

Women with shallow knowledge often show such expressions. After they estimate that the same sex who suddenly intrudes, the skin will not affect their ability to compete with women in this narrow sky, and they feel relieved.

Wang An's cold voice sounded again: "Brothers have companions, there are civil servants on duty in the Wenhua Palace, and you are not a palace maid, so don't come here to make trouble."

"Hey, remember your father-in-law's instruction." Ke Yinyue replied in a low voice.

While talking, I arrived at the side hall behind the Wenhua Palace, and a female official came out to welcome Zheng Haizhu to change clothes.

"Mommy, you stand here, and you are not allowed to go in front of the Wenhua Palace until the buddies are out of class." Wang An ordered.

Ke Yinyue smiled softly: "The father-in-law frightened the servants with such a serious face."

Wang An stared at her fiercely, and reprimanded her with a suppressed voice: "Ke Shi, don't think that you are the wet nurse of the eldest son of the emperor and the opponent of the Wei Dynasty, so that your bones are floating around in the palace. According to the ancestral system, When brother is six years old, you should leave the palace. You have stayed in the palace for many years, if you still know what is good or bad, you should restrain yourself, and don't act carelessly to cause trouble for brother!"

Ke Yinyue lowered her eyes, the corners of her mouth were still curled up, as if she was affectionate, but her heart was filled with killing intent.

A eunuch surnamed Wang, don’t think that you are the companion of the Long Live God, so you just show off your power, the old lady will take care of you one day.

Zheng Haizhu put on the big red robe prepared by the Ministry of Rites, and came out to see Ke Yinyue standing in the porch, bowing and standing quietly, pretending to be obedient, probably because Wang An had made her behave.

"Master Zheng, I dare to ask, how long will it take for you to give lectures?" Ke Yinyue asked earnestly when Zheng Haizhu passed by her.

"what happened?"

"Usually at this time, it's time for my brother to have some snacks."

"Prince, didn't you have breakfast today?"

"Yes, but brother, every day, between Chen and Si, I have to eat Naipizi or Wuren glutinous rice cake."

Zheng Haizhu stared at Ke Yinyue, but his tone was gentle: "The Ministry of Rites never told me that eating snacks is more important than lectures."

Ke Yinyue's eyes flashed, and she immediately said in a sly voice: "Your maidservant should die, this maidservant has offended master."

Zheng Haizhu stopped talking nonsense with her and walked towards Wenhua Hall.

Lu Xiangsheng, who dared not move at the bridgehead but was already anxious, was finally found by Wang An and hurried to join Zheng Haizhu.

"It's nothing, let's go into the palace, let's talk first, and then talk about it later." Zheng Haizhu softly comforted Lu Xiangsheng who was still showing anxiety.

……

In the Wenhua Palace, Zhu Youxiao and Zhu Youjian saw Wang Gonggong leading the red-robed officials in, they got up without hesitation, and walked around to the front of the desk.

Zhu Changluo had just ascended the throne, and Zhu Youxiao had not yet been crowned prince, so it was not necessary for the lecturer to salute him, but the two princes had to salute the teacher.

The two brothers had already done this process to Sun Chengzong who taught the Four Books yesterday, but when they raised their heads after bowing today, the curiosity in their eyes overshadowed their respect.

After all, she is a female master.

Well, this Master Zheng seems to be about the same age as the two maidservants, but he doesn't have the arrogance of Mistress Dong Li, let alone the anger on Mistress Xi Li's face that always dislikes everyone.

After Wang An exited the hall, Zheng Haizhu said with a slight smile, "Your Highness, let's start talking. Put the books together first, I need a bigger one."

"Wang Chengen, move the table." Zhu Youjian ordered his companion to read.

His reaction always seemed to be a beat faster than his brother's.

Zheng Haizhu glanced at the little eunuch who came up to push the table.

Wang Chengen?
Is it the one who hanged himself on Meishan with Emperor Chongzhen after Li Zicheng captured Beijing in history?
She couldn't help but glance back at Zhu Youjian.

In another time and space, the future Emperor Chongzhen is still a young gentleman in his early ten years old, with delicate features and shining eyes.

In contrast, Zhu Youxiao, who is unknown whether he will become Emperor Tianqi in a month, although his facial features are closer to those of an adult man, the expression on his face is more childish.

After the two desks were put together quickly, Zheng Haizhu signaled Lu Xiangsheng to open the big box they brought.

A large pile of mortise and tenon organs clattered all over the table.

Zhu Youxiao's eyes instantly became brighter than his brother's.

He was about to ask what it was for, but he heard a cough from outside the hall.

When everyone turned their heads, they saw Sun Chengzong, dressed in a five-rank official uniform, stepping into the hall.

Zheng Haizhu had already been told that Sun Chengzong, the former official of the East Palace and now waiting for promotion in Zuochunfang, was in charge of the prince's admission to school.

"Sun Gong." Zheng Haizhu saluted Sun Chengzong.

Sun Chengzong looked serious: "I heard that Xu Gong, who led the lecture, is ill today. What is Master Zheng going to say to the two Highnesses?"

"Grandfather Sun, I have been ordered to explain the firearms method to the princes."

Sun Chengzong glanced at the lumps on the table, and said coldly: "Should I learn from Lu Ban first when talking about firearms?"

Zheng Haizhu came prepared, and immediately took out the first volume of "Elements of Geometry" from the bookcase.

"Mr. Sun, please look at this. This is a Western book written by Mr. Xu. When talking about firearms, artillery should be mentioned before guns, because the system is simpler. But firing artillery on the battlefield is actually much more difficult than firing guns, because The angle of incidence of the projectile must be calculated with the degree board and gun gauge. This requires geometry. As for the wooden blocks on the table, they all have tenons, and the next official worked with Lu Juren to splice them into squares, circles, and triangles. Wait for the shape to assist in the explanation.”

Sun Chengzong listened to the woman's unhurried and methodical words, and the doubts in his heart faded by three points.

He walked to the desk and picked up a curved piece of wood.

Zheng Haizhu said: "This is the fan-shaped side, four fan-shaped, connected by mortise and tenon structure, it is a perfect circle."

Zhu Youxiao, the eldest son of the emperor on the opposite side, said enthusiastically: "I will do this."

Just as he was about to reach out to splice the tenons, he suddenly retracted.

A 16-year-old boy, after many years of submissiveness under the control of Concubine Zheng and Li Xuanshi, now even Sun Chengzong, who is definitely a courtier who is definitely his father's confidant, is a little afraid.

Zheng Haizhu said, "Your Highness, please connect."

As he spoke, he pushed the four arcs in front of Zhu Youxiao, and then pushed three straight pieces of wood to Zhu Youjian: "This can be put together into a triangle. We calculate on the battlefield, to what elevation angle the gun barrel should be adjusted, can the shells To hit the enemy, you must use a triangle. I, the white armored cavalry of Jin after the defeat of the Ming Dynasty at the head of Fushun City, just adjusted the angle of the artillery."

When Sun Chengzong was not a Jinshi in his early years, he went to Datong Mansion with the officials who hired him as a tutor. The place was on the border of the empire, so that Sun Chengzong learned a lot of military combat experience while wandering there.

At this moment, when Zheng Haizhu talked about actual combat, he suddenly felt cordial, and his face finally became warm.

"Well, today's lecture seems to be more interesting than the old man took you to recite the classics yesterday." Sun Chengzong even laughed at himself.

But the people in front of him were either his students or his subordinates, none of them dared to really laugh.

Sun Chengzong waved his hand: "Don't be afraid, the old man just came to see the novel tricks. The six arts of a gentleman, ritual and music, shooting and counting, the old man watched, this method of attacking firearms can at least combine the shooting, defense and counting The three arts. Long Live Lord Shengming, taught by Xu Gong and Master Zheng, should not be under the Four Books. Your Highness, study hard."
