His Royal Highness cried miserably. When he stood outside the hall, he could hear the howl of the little guy, mixed with the sound of the emperor busying himself to coax the children. The guards stood outside the hall and stopped two important officials who were summoned to thank the emperor, with an embarrassed look: "Please ask for the Xiang and Ming Xiang to stop, the emperor is busy."

What are you busy with? The noise is too loud, you will know at first hearing.

Soetu: "..."

Nalan Mingzhu: “…”

The two old opponents looked at each other and showed disgusting eyes to each other.

Nalan Mingzhu sneered, walked away a few steps, and left him three feet away.

Soetu didn't get to keep Mingzhu's sarcastic eyes. He felt sore when he just listened to the child's crying. He asked the guard in a low voice: "Your Highness rarely cry. What's going on?"

The guard shook his head: "Please forgive me for not knowing."

At this time, you could vaguely hear a few words about the Prince's crying, "Ah, the wind is over! A waste of man!"

Kangxi: "Yes, yes, I'm too much, I'm a bad guy, don't howl, don't cry, I'm a headache."

Seeing the guard's increasingly awkward and stiff expression, Soetu stopped talking.

So, was the Emperor and the Crown Prince who made him cry?

He secretly complained in his heart: What are you doing to bully your child?

Listen to how sad and pitiful His Highness the Crown Prince crying!

Nalan Mingzhu's expression was complicated and difficult to tell. If you look carefully, the smile that had been hanging on the corner of his mouth for many years has not yet fallen. The smile was in his eyes. Anyone who saw it felt that he was kind and kind. Only Soetu, who had been an old rival for many years, knew how sinister and cold this was an old guy.

In the hall, Kangxi said to him with a angrily voice: "You see, it's all like this, just crying is not a problem. You have to solve the problem, right? Baocheng's mouth is covered with blood now, you wipe it first, wipe it first!"

Yinreng did not cooperate, and his gums were bleeding all the time. They slid from his mouth and fell on the ground. They looked scary. Kangxi was shocked and anxious and frustrated. He called people outside to call Dr. Jiang.

"The teeth can grow even if they are gone. The immortal has taught you how to change teeth. In a short while, the front teeth will grow out." The emperor's greatest patience in his life was left to this stupid son.

Yinreng choked up and said, "Ama Khan, it's unreasonable."

"Toothless, ugly monster!"

Not only is he ugly, but he also speaks indifferently. He is no longer a decent person!

It took half a year for the front teeth to grow, and he has no shame to see anyone in the past six months.

Kangxi was worried: "This is all pulled down, what do you want?"

"I will not learn from Huang's book."

Yinreng wanted to lock himself in a small house, but no one saw him until he grew small teeth.

"This won't work, your studies cannot be stopped," the emperor rejected Yinreng's request.

Yinreng cried with grievance: "I'm not seeing anyone!"

"It's not okay to not see anyone. If you want to save face, then at most you can let the master teach you alone."

Whether it is embarrassing in front of brothers or brothers, or in front of masters, it is impossible.

Yinreng stopped howling, and changed to sobbing in a low voice, shaking his head while sobbing. Tears and snot and blood were all the same, which was a terrible scene.

Kangxi gave him a handkerchief, and Yinreng wiped his face covered, wiped his tears and twisted his nose. He spread the handkerchief and opened his mouth and vomited a ball of blood.

If the child doesn't howl, the magic sound is gone, but he looks so pitiful.

The emperor also held Yinreng's small front teeth in his hand, and it was not right to give them to him, nor did he not give them to him. He had to deal with the trouble. If someone spreads it, he bullied his son and cried. Where can he put his face in it?

Yinreng whined, "I won't see the teacher, I won't see the teacher..."

You can't succeed without seeing your master, and you can't help but study.

"The third brother should come to the study after his birthday. Don't you expect him to come to school?"

The younger brother admires Prince Ge Ge. The most unaware thing about Wuya is that the third brother!

He shook his head like a rattle again, Kangxi sighed and rubbed his eyebrows.

Alas, why is it so difficult to reason with children?

"Every child will change teeth when he is at this age. It's not just you who are embarrassed. Isn't the boss also here? He is two years older than you, and his front teeth have fallen long ago, and he hasn't seen him cry. Why are you howling here?"

"Khan Ama, I haven't pulled my brother's teeth, I'm going to remove my teeth, I'm going to pass the wind! A waste of man!"

Kangxi: "…"

The emperor smiled tiredly and was unable to reason with the child again. This time he wanted to be a ruthless father and force his child to go to school. What are the shameful things? That was spoiled and he couldn't spoil him!

Yinreng heard the emperor's words and asked him to continue studying, and even scolded him for his spoiled words, showing a hurt expression. He couldn't believe that Khan Ama was so heartless!

Kangxi was furious when he saw him, and his scalp began to numb again. He was so upset by this stingy little thing that he left his eyes to see him. When he heard that Doctor Jiang had arrived, he hurriedly summoned Doctor Jiang in.

The old empress dowager often sees the Empress Dowager and has rich experience. When he saw Yinreng's small teeth, he immediately gave a conclusion: "Your Highness the Crown Prince changed his teeth in advance, so he grew fast. He had a light diet before the new teeth grew. It should not be sweet or spicy. It was normal for the teeth to fall off and bleeding. I prescribe a child decoction for Your Highness to clear heat and detoxify, and a meal would be enough."

The other thing was nothing. The old doctor reminded Yinreng not to always lick the empty gums.

You can't eat sweet food, and you can't touch the sweet milk or pastries you eat in the afternoon. When the imperial physician said that he had a light diet, all the things that Chinese medicine recognize as hair products were also excluded from Yinreng's recipes.

The old doctor cleaned Yinreng's mouth and asked him to rinse his mouth. He rinsed a whole pot of blood in the palace. When the palace maid took it out, Soetu was so scared that he thought it was the emperor who beat the child.

After cleaning it, Yinreng closed his mouth, tightened his face and acted seriously. He could speak less if he could speak, and sometimes he turned his aggrieved and accused eyes to Kangxi.

"Okay, okay, this matter is over here. You go down and just look for Doctor Jiang if you have anything to do," Kangxi felt guilty, but he did not admit that he had done something wrong. He coaxed the child away with a feeling of being a furious, without any responsibility or responsibility as a father!

Yinreng walked out of the hall and saw two adults waiting outside, among which was his dear third grandfather. This time, when he saw the third grandfather, his eyes were red with grievance. When he saw someone standing there looking at him, Yinreng glanced at the man, pursed his mouth and stopped talking.

Finally, he looked at his third grandfather, and Yinreng passed by him.

Soetu had never seen the prince be so depressed. In his impression, the little prince was lively and active, laughing and naughty, and no one had ever suffered any grievances. He secretly guessed what happened to the emperor and the prince. When he heard Kangxi summoning him, he saw only a few drops of fresh blood on the ground, and his face changed immediately.

Kangxi forgot to return the little front teeth to Yinreng. The old father who did the wrong thing was entangled for a moment and simply refused to return it, so as not to make the child cry and coax it into trouble.

Yinreng was extremely sad, and the system came to comfort him.

[The child is a brave man, just change his teeth, don't be afraid of embarrassing. Brother Tutu's two front teeth have fallen out! If you don't believe me, go and see.] [The child's father is a novice father, a fool father. He still loves you. He will not make the child happy, but Xiaomei will coax him!] Yinreng: If you want to make Gu happy, just coax him, and even tell him to Gu. You are also a fool.

【system:……】

[Don't be angry, think about some happy things! Xiaomei can play cartoons for you and also give you delicious food that doesn't hurt your teeth!] Yinreng was a little sad at first, but when he saw the white tiger Xiaomei scratching his ears and his forehead, he used all his tricks to make him happy, he suddenly felt that it was great to have Xiaomei accompany him at this time.

Although Xiaomei is stupid and can't teach people, in this world, anyone may abandon him, but only Xiaomei will not abandon him!

Thinking about this, Yinreng felt that he could like Xiaomei a little more. He was in a good mood and asked Xiaomei for a rating list, which gave the system a perfect five-star praise.

Baihu was crazy and jumped to Yinreng to circle around him, giving the words of praise to Yinreng as if they were not allowed.

[The children are so sweet, they are the cutest children in the world!]

Yinreng bent his lips slightly and his mood improved. At this time, Yuzhu informed outside, "Your Highness, I'm here to find you."

It turned out that after the two important officials had met Kangxi, Soetu took the initiative to ask for the prince before leaving.

Regardless of whether the emperor would blame him, he felt anxious and uneasy when he saw the blood in the hall, and asked Kangxi if he could come to find Yinreng.

Kangxi agreed to Soetu's request for the first time and said to him: "The prince's teeth are falling off, and he is sad. Please comfort him more."

Soetu still thought it was something! The emperor was stunned for him and then he responded in a daze, retreated and came to Yuqing Palace.

When he saw Yinreng, the little guy's mood had stabilized. With the comfort of the system, he mustered up the courage to face the current situation of his speech leaking. He looked serious and called him "Silly Grandpa."

Not only was Soetu not angry, he also showed a wolf-grandmother-like smile, and he would pick up any pot without opening: "Your Highness has started changing teeth, you have grown up!"

Yinreng glanced at him, pursed his lips, and said "um" without any high spirits.

Seeing this, Soetu wisely changed the topic: "The concave and convex glass mirror that His Highness had asked someone to study before have already achieved results. Look, do these two pieces of glass look like your requirements?"

He quietly took out two pieces of glass from his sleeve and carefully handed them to Yinreng's hands.

Yinreng was really interested. He flipped over and over, looked at them in his eyes, and took them to read them. He really saw the effects of concave glass and convex glass.

"Silly grandpa, the craftsmen must have developed more than just these two pieces, right?"

Soetu nodded with a smile: "Your Highness has inspired the craftsmen. They have studied it and found the difference in the mirrors of different glass arcs. If this is true, then the Qing Dynasty can use this to study the rare treasure "teleoscope" brought to us by the Gentiles!"

"When Joshua Wong wrote the book "Theory of Telescopes" that explained how to make telescopes with the distance between concave and convexity. However, the Qing Dynasty did not have such a technology and could not make telescopes, so that the princes and nobles asked the Gentiles to buy telescopes at a high price for rare treasures," Soetu sighed: "A telescope can be worth 100,000 taels of silver."

Yinreng was shocked: "They rob money!"

One hundred thousand taels, fifty million candied haws! Is this what humans do for a telescope to exchange for 50 million candied haws?

"Those Gentiles are good and bad! They bullied me, the Qing Dynasty, but there were no craftsmen to develop telescopes," Yinreng beat his chest and stamped his feet, but the root cause of not being able to create telescopes? Isn't it that people don't learn physics?

It is obvious that the Qing Dynasty also had such books, such as "Mengxi Bitan", "Zhengmeng Zhu", etc., but very few people are willing to study them. What does this mean that the Qing Dynasty lacks scientists!

"Don't worry, your highness, the craftsmen have already gained a glimpse of their reputation. I believe that it will be possible to create a telescope in the future." When talking about this, Soetu was full of red light. As long as the "telescope" was created, it could be used on the battlefield, and the nobles could also use it. There is no need to ask the Gentiles to buy it at a high price, and they were deceived by those cunning and greedy Gentiles.

"Your Highness guess how much does these two sides of glass cost?"

Yinreng tilted his head and thought about it, and compared it: "The money is for a hundred candied haws."

Soetu laughed: "No, it only costs ten candied haws to make it. The cost of adding up the two sides is only about twenty candied haws."

"Wow!"

It's so cheap!

Yinreng became excited. He told Soetu: "If you can study thoroughly, you can also make glasses. Use a concave mirror as a distance glass. According to different curves, glasses can be tailor-made for people with different vision."
