She Song

Chapter 209 Good Prince or Bad Prince

Han Xiaoyao had already heard Zhao Fujin mention Dong Xiaowan's question, so he smiled and invited the executive vice president to answer it.

Dean Zhao first affirmed Dong Xiaowan’s attitude towards learning and research, and then said: “Looking at this problem separately, one is the relationship between load and lift-off height, and the other is the relationship between fuel thermal energy and buoyancy. To address these two issues, we can Test and verify.”

Han Xiaoyao immediately wrote down two topics on the blackboard, and at the same time wrote "Measurement of temperature and wind force at different altitudes", then pointed to Dong Xiaowan and said, "You will be responsible for this issue."

Dong Xiaowan was stunned, how to measure this and what should be used as a standard?
"There is no standard? Then just set a standard." Han Xiaoyao directly blamed it.

Dong Xiaowan's eyes widened, the young prince really opened his mouth to come!

Neither the wind nor the temperature can be seen or touched. Aren't you making things difficult for me?
Han Xiaoyao shook his head and retorted: "Who said you can't see it?"

Dong Xiaowan believed that the wind was invisible and traceless, so she said: "As long as Dean Han lets me see it, I can set the standard!"

"Okay! Wait a moment!"

Huh!This little girl actually dares to challenge the King of Zhenbei, so brave!
Everyone felt it was new, and seeing that Han Xiaoyao was not acting domineering, they all snickered in private.

However, they were more curious, how could King Zhenbei show the wind to everyone?
Han Xiaoyao cut out a square piece of paper on the desk, cut a section at the four diagonal ends, folded it into a paper pinwheel in a few simple steps, and fixed it on a small bamboo pole with a bamboo stick.

With just a slight wave, the windmill started spinning, and then it was handed to Dong Xiaowan.

"Now, you should see the wind, right? Think about it carefully, how are you going to establish wind power standards?"

It’s actually a windmill!
This……

Everyone showed the same expression, including Dong Xiaowan, who was holding the windmill in a daze.

That's right, as long as the windmill blades rotate, it means there is wind. The faster the windmill rotates, the stronger the wind. Why didn't I think of such a simple truth?
At this time, she felt aggrieved that she had been tricked by the young prince.

Although she saw the "wind", she was completely confused about the setting of standards. She was too embarrassed to take back her boasts about Haikou in public, and she had no idea about the temperature.

Han Xiaoyao couldn't care less about "Miss Gang Jing" for the time being, and then proposed a research topic based on the various links of the hot air balloon.

Li Juan needs to study how to sew giant balloons firmly, Qiu Jiujin needs to make thin and flexible leather as the balloon fabric, and Liu Shumiao is responsible for making precision devices required for various projects.

There are many auxiliary topics. The furnace master in the steel factory needs to select the best quality coal, the bamboo weaver needs to weave light and strong hanging baskets, and the weaver needs to make ropes of various strengths...

A total of 81 hot-air balloon-related topics were listed, and [-] people were divided into [-] topic research groups based on their personal strengths and interests.

There were more groups of five or six people, and there were only two or three people in the group. However, the problem of wind and temperature measurement was too abstract. Looking at the frowning Dong Xiaowan, no one dared to try it.

Of course Han Xiaoyao knows the answer to the problem, and it is very easy, but he is not going to "cheat" this time.

After all, these people are likely to be academicians in the future, and they must have the scientific research spirit to dare to explore, innovate and face failure.

It was almost noon, and Han Xiaoyao had ordered people to set up a buffet in the big tent. It was a must for the first batch of bachelors to eat and drink well.

There are nearly twenty kinds of various dishes kept warm by charcoal fire, as well as various kinds of noodles, fruits, and soups. There are long tables at the end, and the rest are foldable dining tables and chairs. There are a total of thirty small square tables for four people. .

"From now on, breakfast, lunch and dinner will all be buffets. All dishes are unlimited. After you finish eating, let the chef cook it on site. You can just choose what you like and enjoy it!"

After Han Xiaoyao finished speaking, he took the dinner plate and took Maode and Xiaowei to take the lead in choosing food.

Maode was okay and picked something light and elegant, but Xiaowei stared at the red braised pork and refused to move. She also looked at Maode's plate, not daring to make any mistakes.

Han Xiaoyao picked up the male spoon and put a full spoonful on Xiaowei's plate: "Eat more to grow faster!"

"Thank you, Your Highness!" After receiving the delicious food, Xiaowei immediately bent her eyes and whispered her thanks, holding the plate and hurriedly followed His Highness.

Your Majesty is so kind!
"My lord, don't spoil Xiaowei too much..." Zhao Fujin deliberately made a second guess.

"I got it, I won't do it again!"

Han Xiaoyao followed suit and immediately added a spoonful of green leafy vegetables to Xiaowei.

Looking at the sudden offer of green leafy vegetables, Xiaowei couldn't refuse, but the corners of her mouth obviously twitched involuntarily.

The prince is really... really... actually listening to His Highness? !
The three of them selected the food and randomly chose a nearby square table to sit down and eat.Fortunately, most of the 81 "new bachelors" knew that the officers and soldiers of the Zhenguo Army Han Ji lived and ate together, so they imitated the two deans and picked out their favorite food on the dinner plate.

Although food and clothing were satisfied, most people still chose more delicious meat and river seafood, and the chef roughly judged the degree of food consumption and started a new round of cooking.

Dong Xiaowan, who had something on her mind, was the last to cook, holding the plate in one hand and pinching the windmill in the other. Seeing that all the tables were occupied, she didn't know where to sit, but she heard Maude's call.

"Xiaowan, come and sit over here with us!"

"Oh!" Dong Xiaowan sat next to Xiao Wei with a dinner plate and thanked him a little embarrassedly: "Xiaowan has caused trouble to the two deans!"

Zhao Fujin and Han Xiaoyao got along well, and realized that the other party did not have strict hierarchical habits in daily life, so he gave the other party a few words of relief.

Seeing that the other party didn't have much food, he reminded the other party not to be hungry. When the new dishes are ready, he can add more.

But Dong Xiaowan was still struggling with the issue of wind power measurement and really didn’t have much appetite, so she politely declined.

Xiaowei knew very well that His Highness needed help in Yanjing, so she would always be kind to others. Seeing that Dong Xiaowan was not in a good mood, and stared at the windmill from time to time, she probably guessed the reason.

She asked in a low voice: "Your subject should be quite difficult, right?"

Although she was not convinced, Dong Xiaowan was self-aware and could only nod her head silently.

Xiaowei secretly said: "Your Majesty must know, how about I help you ask?"

Dong Xiaowan was shocked, could the young prince really know?

Xiaowei obviously understood the other person's eyes and nodded firmly.

After Han Xiaoyao and Zhao Fujin had lunch and parted with Dong Xiaowan, Xiaowei winked at Dong Xiaowan and followed closely.

After leaving the tent, Xiaowei took the opportunity to ask questions about wind power.

There's nothing Han Xiaoyao doesn't understand. Although he can't give a direct answer, a hint from the side is still allowed.

"Blowing that windmill more may give you the answer. If not, I can only go and see the folk windmills in person!"

Although Xiaowei didn't understand, she still trotted back to tell her new friend.

"Blow the windmill?"

Dong Xiaowan immediately picked up the windmill and tried to blow it. The paper windmill stopped after spinning and blew it again... Still nothing?

Seeing that Dong Xiaowan was still confused, Xiaowei took the windmill and blew hard, causing the windmill to spin very fast.

Ugh?
Dong Xiaowan felt a different thought. If you don’t blow, the windmill will not move. If you blow lightly, it will stop after a few turns. If you blow hard, the windmill will spin fast...

Can the difference in wind power be measured by the speed of the windmill?
The more she thought about it, the more she thought this method should be the answer, and immediately pulled Xiaowei and ran out of the tent.

"Dean, I found the answer! If the wind is strong, the windmill will spin slowly, but if the wind is strong, the windmill will spin very fast...right?"

Han Xiaoyao nodded and said: "This is indeed the truth, but it is not enough. What you have to do is to measure, that is, to give the wind force an intuitive and clear mark like the star point of the scale. By the way, the measurement requirements for temperature are the same. .”

Seeing Han Xiaoyao and Zhao Fujin's leaving figures, Dong Xiaowan wanted to cry but had no tears.

Xiaowei turned to Dong Xiaowan and said: "The prince knows, but he said that this is an assessment for you. If you fail, you will only be a bachelor forever... I'm sorry~"

With apologetic and sympathetic eyes, Xiaowei also left.

ah ah ah ah ~
What kind of bad prince is this?
Suddenly, something vaguely seemed to come to mind, immediately reminding Dong Xiaowan who was going crazy.

So, she immediately asked for leave and returned to the Jiedu Mansion.

"I'm going out of town!"

Pharmacist Guo, who was looking cheerful, could not help but frown and asked, "Where are you going?"
