Before the preparations were about to be completed, Ying Zheng finally arrived at the large playground of Xianyang Academy with the Minister of Civil and Military Affairs.

Seeing this, all the teachers and students hurriedly got up to greet His Majesty.

Ying Zheng sat on the tall Son of Heaven and waved his hand domineeringly: "Flat." ”

After the words fell, he got out of the car under the escort of the personal guards and looked towards the playground rostrum.

I happened to see the petite figure of Xu Yan coming over.

In the face of such an excellent girl, Ying Zheng's lips raised a smile, and he stepped forward with his long legs: "How is it, can you be ready?" ”

"Father, the emperor, just waiting for you and the ministers."

Xu Yan took her father's big hand and walked towards the rostrum, where the most important place had long been reserved for His Majesty.

As soon as the father and daughter got on the high platform, the seven students who went down to prepare brought their props back to the playground.

Excitedly shouted: "Principal, Vice Principal, the students are ready, do you want to start now?" ”

Xu Yan looked at her father beside her with a smile: "Father, you can give orders." ”

"Then it begins."

The girl gives herself face, and Yingzheng has no reason not to accept it.

"Yui."

Seven students agreed, and one of the boys stepped forward, holding the tweeter they had worked out and began to speak:

"Dear Principal, Vice Principal, Teachers and Students, Hello everyone, ...... today"

The students talk about what they are going to do today and make clear the purpose and purpose of the experiment.

"This student is good."

Ying Zheng listened to the student's opening remarks, tilted his head slightly and said to the nine girls beside him, "It's worth cultivating." ”

Xu Yan smiled with satisfaction: "Father is right, but if he is more interested in scientific research, I would rather let him be a professional scientific researcher." ”

Xu Yan, who has experience in later generations, knows very well: management talents are easy to cultivate, and scientific research talents are rare.

In particular, this kind of spiritual scientific research talent is really rare.

She just came up with basic science and technology textbooks, and the result is now that both the School of Physics, the School of Chemistry, and other colleges and students are teachers and students.

On this basis, they all carried out different branch research.

Sometimes Xu Yan feels that the wisdom of these people is too good, and she doesn't want to suppress and restrict the development of this area.

Ying Zheng: "Well, your school, you have the final say. ”

"Father, how can you say that?"

Xu Yan smiled, "Don't forget that you are now the principal of Xianyang Academy Palace (sacrificial wine)." ”

"I'll just put it on my name."

Ying Zheng knows very well that if this school didn't have nine girls, it wouldn't be what it is today.

"Let's not talk about that, let's see what kind of results these students will experiment."

Zu Long took the initiative to change the subject, and looked at the tripod ladders of different heights in the center of the playground, "This height difference is a bit big." ”

"Only in this way is the data from the experiment more obvious."

She was very satisfied with what the students had prepared, "The size of the stone is quite suitable. ”

Ying Zheng looked at the stone that was not very regular, and was a little puzzled: "Huh? Why don't they test it with stones that train their arm strength? ”

"Father, the real meteorite from the sky produces high-intensity friction and fire."

"When it actually falls to the ground, it forms an irregular shape, which is more irregular than this. ”

"What these students have to do is to restore the appearance of the meteorite as much as possible, so that the test effect will be stronger."

"First of all, we use the same stone, lower it from different heights, let it fall freely, and see how it can hurt the ground."

The boy who was in charge of the experiment explained to the tweeter.
