Chapter 226 This Emperor Has More Trouble Than When I Was a Child Going to School
"I was originally worried that we would be away for too long and Zhuang'er wouldn't be able to handle it alone. Now that this is the case, I'm relieved."

"Zhuang'er has reached the age of twenty and it's time for him to stand on his own. You, as his mother, still treat him like a child. How can he shoulder the responsibility of the Han Dynasty in the future?" Liu Xiu said, then turned and walked out the door.

"Your Majesty, you are busy with official business so early in the morning. It's cold outside, so put on more clothes." Yin Lihua chased out with a coat.

"Hey, can one of this couple go back? They are always showing off their love in front of me." Wang Mang rolled his eyes at Liu Xiu's back.

"Brother Wang, who told you to always say that being single is great? Why don't you find a partner?" Su Jiahe said with a smile.

"Okay, okay, go do what you need to do." Wang Mang shook his sleeves, put on his medicine box and medical books, and strode out of the yard.

Suddenly, a gorgeously decorated carriage arrived at the door.

"Someone from the palace is here to pick me up. I'm going to teach the little emperor. See you in the evening." Yingying ran over quickly.

"Sister Su, it's time for school to start, and we should leave." He Shuangqing had already packed up her things and pulled Su Jiahe out the door.

The days passed by in a hurry, and soon it was Deng Sui's birthday again. Su Jiahe and others were invited to the palace, and Deng Sui was already waiting in the study.

"Sister Deng, happy birthday!" Su Jiahe took out the gift she had prepared long ago. "This longevity painting was created by hundreds of students from the girls' school. They wanted to express their gratitude for giving them the opportunity to study."

"Okay, okay, the children are so thoughtful." Deng Sui took the longevity picture and put it away carefully.

"Where is Yingying? Why hasn't she come?" Wang Mang suddenly asked.

"Yingying is giving the emperor a lesson."

"Today is your birthday, and they're still in class. They're so hardworking. Can we go and see?"

"Okay, I also want to go see them."

Led by Deng Sui, several people came to the emperor's study, only to see Liu Hu holding a pen and looking worriedly at the book. Yingying was sitting beside him, giving him a lecture in a serious manner.

"This Pythagorean theorem states that the sum of the squares of the two right-angled sides is equal to the square of the hypotenuse..."

"I understand, sir. It's three strands, four strings, and five."

"Then let me ask you, if the length of this right-angled side is five, and the length of this right-angled side is twelve, how do you calculate the hypotenuse?" Yingying said, drawing a picture on the paper.

"This..." Liu Hu frowned as he looked at the triangle on the paper. He turned the pen around in his hand, but he didn't know where to start.

"Didn't I just tell you that the sum of the squares of the two right-angled sides is equal to the square of the hypotenuse? Now that we have two right-angled sides, can't we find the hypotenuse?" Yingying patiently guided Liu Hu.

"Oh, I see. We need to calculate the squares of these two sides first," Liu Hu nodded. "This side is five. The square of five is... what was it?"

"Five times five equals twenty-five. Isn't that the multiplication table?"

"Yes, five times five is twenty-five, so twelve times five is..."

"Wait a minute, what are you doing with twelve times five?" Yingying quickly interrupted Liu Hu. "I explained the definition of square to you before. Have you forgotten it again?"

"So what is the square of twelve?" Liu Hu looked at Yingying innocently.

Yingying took a deep breath and scratched her head speechlessly.

"Sir, don't be angry. The mathematics and science you teach are too difficult. I used to study mainly the Four Books and Five Classics and rarely learned these." Liu Hu looked embarrassed.

“Mathematics and science are the foundation of social development. The entire Han Dynasty is now developing science and technology. How can you, as the emperor, not know them?” Looking at the scene before him, Wang Mang covered his mouth and almost burst out laughing.

"Haha, this emperor has a harder time than when I was a kid going to school."

"Alas, Hu'er's talent is average, but fortunately he is obedient and willing to learn. I hope that with time, he will one day come to his senses." Deng Sui couldn't help but shook her head.

Half a day later, Yingying and Liu Hu noticed that Deng Sui and others had come to the study.

"Okay, let's not go to class today. Change your clothes and go to the banquet." Deng Sui said.

Yingying seemed to be suddenly pardoned. She quickly put down the book and went back to her room to change clothes.

Since the development of science and technology requires a lot of money, Deng Sui's personal life has always been relatively simple, and her birthday party was not very luxurious. She only invited a few close friends and set up a table in the imperial garden.

"It's a pity that Emperor Guangwu has a special status and cannot come to the palace for the banquet. I have not met him many times." Deng Sui said during the banquet.

"It's okay, let's eat first, and I'll pack some for him to take back." Wang Mang waved his hand.

At the same time, Liu Xiu and Yin Lihua ordered a table of wine and food in the house outside the palace.

"Your Majesty, isn't it a bit extravagant for just the two of us?" Yin Lihua said as she looked at the sumptuous dishes.

"Today is Deng Sui's birthday. Since we can't go into the palace, let's celebrate here. Come eat quickly, or Wang Mang will come back and give us leftovers."

Another four years passed in the blink of an eye, and Su Jiahe and the others had reached the time limit for their journey and had to return. When they parted, Deng Sui held Su Jiahe's hand, tears streaming down her face.

"Sister Su, thank you so much for your help. Thanks to you, the Han Dynasty has enjoyed good weather and the people live and work in peace. We say goodbye today, and I wonder if we will meet again in the future."

"Sister Deng, don't cry. Maybe we will meet again." Su Jiahe was also very reluctant in her heart, but still smiled and comforted Deng Sui.

"Teacher, why are you leaving so soon? Who will teach me in the future?" Liu Hu, who had already grown up, stood in front of Yingying and cried like a child.

"It doesn't matter. There are many talented people in various fields in Dahan now, and they can all be your teachers. After I leave, you must not slack off in your studies and must keep up the good work." Although Yingying is still a young girl, her tone is like that of a stern yet kind old gentleman.

"Brother Wang, you have made great contributions to the Han Dynasty, so I don't need to say thank you." Liu Xiu gave Wang Mang a hug.

"Hey, why don't you say thank you?"

"A simple thank you is not enough to show your contribution. If you need anything, I will bring it back to you."

"No, no, I have more material resources there than here, and I lack nothing." Wang Mang waved his hand.

"By the way, I still remember that you gave me a jade pendant." Liu Xiu said, taking out the resin handicraft from his sleeve.

"Ah, this is not a fake, why do you still keep it?" Wang Mang was a little surprised.

"I want to thank you. Because of this sample, we were able to develop resin early on. It has a lot of uses." Liu Xiu smiled slightly.

"That's good. You can keep it as a souvenir." Wang Mang said, "But, Xiu'er, I have a question that I've always had. Since I'm leaving soon, I might as well ask it today."

"Okay, just ask."

"Honestly, I've made such great contributions to the Han Dynasty. Aren't you afraid that I might usurp the throne again?"
