"You also know that the palace is a bit messy now. As a prince, you are a person who reports this matter, you must be more cautious. You can't go out for freedom and freedom when the princess and the princess are sad." Sun Yingying said with confidence. She felt that Bai Yixiu's attitude was problematic and could not relax like this. "You were a sick person in the past. Even if you do something excessive, no one would care about you. But now it's different. Soon, you will become a healthy person and a person who can threaten the prince's status. So you should be careful, so that you will not end up fighting with your brothers and fighting to the death. What's the point? We travel here just to be comfortable and interesting. We are not here to fight."

Hearing this, Bai Yixiu put down the book in his hand, got up and walked over, poured himself a glass of water, and took a few sips, "You make sense. Of course I understand, but now I start to worry too much. Is it a bit too early? In addition, if I don't tell the prince and the princess, there will be endless troubles in the future. First of all, if there is no legitimate son, the emperor naturally feels that he will be shorter than others; secondly, I know clearly but don't say it, that is a kindness."

"Okay, what I said makes sense." Sun Yingying nodded, took the water that Bai Yixiu poured for her, and took a few sips. "When the Crown Princess is well prepared, she will have more sons. This will not only make the Crown Princess' status stable, but the Crown Prince doesn't have to worry about the problem of offspring."

"Yes, then, I will be a wise king, a prince who can make money and be obedient." Bai Yixiu said softly, "What's the point of being an emperor? I'm so tired, I don't want to do it."

Sun Yingying nodded, "Yes, we don't become emperors. Although your brother is not as good as your father's emperor, that's not good. Then we will travel together. Oh, the carriage is bumpy now and the road is not good."

"The road is not good, so we will build the road, but this is relatively slow. Even if the cement thing is made, the output is not very high for a while, so we have to wait, but the carriage can be shock-absorbed by adding a spring." Bai Yixiu's eyes lit up and he stopped reading, "Come on, Yingying, let's design a carriage together?"

"Carriage?" Sun Yingying was stunned, "Uh, I can't do anything other than medical skills, especially in terms of design."

Bai Yixiu didn't care, "You don't know, I can do it. Please help me with some calculation questions. When you were in school, chemistry and physics were very good! You should be able to use this knowledge."

After hearing Bai Yixiu's suggestion, Sun Yingying nodded repeatedly, "Okay, let's design a carriage that is not bumpy together."

Bai Yixiu took Sun Yingying to see the carriage together, which was very complicated, especially made into a royal carriage.

After all, there is not even rubber now, and the wheels and all parts are made of wood and iron nails. There is too many parts involved. Shen Bingzhu, a layman, has no way to design a better carriage based on the existing ones.
