Zhu Youxiao laughed. "Isn't this little Wu Yue? She seems to be studying!" He wondered what wish she was trying to fulfill that made her work so hard.
Zhu Youxiao signaled the guards to stay where they were, and he and Li Chengcheng walked over quietly with light steps.
Little Wu Yue messed up her hair. When she heard footsteps, she became even more irritated and started to yell, "Zhao Dabao, stay away from me. If you bother me again, I'll beat you to death."
Puff! Li Chengcheng couldn't help but laugh. This little girl knows how to beat people up. Hearing the name Zhao Dabao, you can guess that it's a boy!
Little Wu Yue heard something wrong with the voice, turned her head with wide eyes, and immediately saw Zhu Youxiao and Hexi's smiles.
Blinking hard, Little Wu Yue recognized him and immediately jumped down from the stone bench with a smile. She knelt down and kowtowed to the emperor, "Your Highness!"
Without the emperor's invitation, Li Chengcheng stepped forward and pulled up Little Wuyue. The little girl was not only sweet-mouthed, but also knocked her head hard, with dirt on her forehead.
Zhu Youxiao chuckled, sat down on the stone bench, picked up the book and looked at it, and said, "Wuyue, if you don't understand something, you can ask the teacher. Why are you scratching your hair so hard that it looks like a chicken coop?"
Wu Yue grinned and said, "I'll figure it out on my own first. If I really can't figure it out, I'll go find a teacher. Besides, I don't think the teacher's level is very high!"
Hey, little girl, you are so arrogant.
Zhu Youxiao extended his hand and said with a smile: "Let me see what difficulties you have encountered. You dare to say that the teacher's level is low, but you can't be proud!"
Wu Yue chuckled, took the book and opened it, pointing out one of the questions to the emperor, "This is it, I can't figure it out."
Zhu Youxiao looked at it, smiled and nodded.
This was already the most difficult problem for fifth graders. It was one he had done in elementary school in his previous life. It was about a ship and a mast, with a touch of solid geometry. He hadn't been able to solve it then, but it had left a lasting impression on him.
It’s not easy to figure it out just by thinking about it, but just take a small stick and measure it, and you can immediately apply the Pythagorean theorem to calculate it.
Of course, the concept of 3D was completely new to Little Wu Yue. Even children several years older than her might not understand it.
"Hurry, you're smiling, so you'll definitely do it, right?" Little May is not only smart, but also knows how to read people's expressions!
Zhu Youxiao smiled and touched Xiao Wuyue's head, bent down to pick up a wooden stick from the ground, took off the jade pendant from his waist, placed it on the table as a boat and mast, and began to explain.
Little Wu Yue blinked her big eyes and listened attentively. Just by looking at the real objects displayed by the emperor and then listening to a few more words, she immediately understood and a look of surprise appeared on her face.
"Do you understand?" Zhu Youxiao stopped explaining. He also saw Xiao Wuyue's expression and didn't need to explain in too much detail.
Xiao Wuyue nodded vigorously and said, "Wansui is really amazing. He can make it just by looking at it."
Zhu Youxiao puffed out his chest, full of pride and satisfaction. "No elementary school question has stumped me." Besides, I compiled all these textbooks. I am the reference book, and I am the complete solution to the textbooks.
"Wuyue is quite impressive." Zhu Youxiao patted Wuyue's head again and praised her with a smile, "At such a young age, you can already solve the most difficult questions in the fifth grade."
Wu Yue chuckled and said, "Because I have a wish, I must fulfill my promise to Your Majesty."
"Whatever your wish is, I will fulfill it now." Zhu Youxiao expressed it generously.
Zhu Youxiao was very satisfied with May's performance. Even if she failed the primary school graduation exam, he would not argue with this little girl.
"Your Majesty, don't you believe me?" Little Wu Yue became serious, closed her mouth and looked at the emperor.
Zhu Youxiao smiled and said, "Of course I believe in May. Since you insist, let's talk about it after the exam."
May then became happy and looked quite confident.
Zhu Youxiao asked about the school's recent situation again, and was relieved to see that May was not dissatisfied.
"Study hard and don't tire yourself out." Zhu Youxiao stood up and told the little girl, "There's no deadline for our agreement. It counts as soon as you finish it."
May didn't refuse this time, even though she felt it could be completed this year. But His Majesty's intentions were good, so you have to follow his lead and don't be ungrateful.
Zhu Youxiao already understood the situation, so there was no need for him to go any further. After saying goodbye to the little girl, he returned to the Qianqing Palace.
……………………
The sound of hooves was neither fast nor slow. The donkey pulled the cart and turned the corner and went straight under the watchful eyes of everyone.
"It should be fine." After Xu Fuyuan said this, he felt that it was too early to draw a conclusion, so he turned his inquiring gaze to Wang Jizhong.
Wang Ji nodded and said, "I think it's OK. Even if we change to a bigger car, it shouldn't have any impact."
"Thanks to Brother Shen's guidance, I was able to achieve twice the result with half the effort." Xia Yunyi sighed, "I'm afraid it's not an exaggeration to say that he is a pedantic scholar."
Xu Fuyuan agreed and said, "Next, let's test the suspension system. Brother Shen said that's the best steering device."
On the basis of axles, it is easy to make a four-wheeled vehicle. All you need to do is change the front wheel suspension to a large disc. The part where the shaft connects to the body of the vehicle can be combined with the front wheel suspension, so that when the horse turns, the front wheel suspension also follows the overall direction.
However, the suspension method cannot achieve steering at too small an angle, and sharp turns at too fast a speed are also difficult. It also places high demands on the structural strength of the front wheel suspension and the entire transmission system.
At this point, everyone should understand that what Xu Fuyuan and others are testing is a four-wheeled carriage with a steering device.
