After a slight pause, Xu Yan continued: "Of course, the relevant research and development process and why several mechanisms will be changed to operate with feet in the later stage must also be clearly recorded. ”

"In this way, the deeds of the eighth sister can be spread to the world, and future generations can understand that innovation is the foundation of scientific development."

"If it weren't for Eighth Sister and her team's courage to innovate, there would be no more prosperous development of Daqin in the future."

"Well, that's a good suggestion."

Listening to the words of the ninth girl, Ying Zheng smiled heartily, "Then listen to Xu'er, Zhen'er, don't dismantle this car." ”

"You build a new one, an improved one, for your father."

"As for the manufacturing process, you also have to make a book, and I have to open a car production factory in Daqin."

"Father, my sons heard it."

Zhen Yan listened to the ninth sister's proposal, and her heart was excited.

She knew that her father and ninth sister were using this way to justify their names, so that they could study more attentively, and also let them understand the importance of research.

"By the way, Zhen'er, you stay in the palace today, and my father has something to tell you."

Ying Zheng saw that the eighth girl understood his and the ninth daughter's intentions, and praised the child more and more.

She, like the Nine Daughters, was not valued by my father at first.

I didn't expect that since the nine girls became a blockbuster, the eight girls have also made such a great contribution.

Especially this speed made Yingzheng understand why Xu'er was so excited when he saw the birth of the steam engine.

By the way, and the steam generator, I don't know if Zhen'er has done any further research?

"Father, the son knows."

Zhen Yan glanced at her father, not knowing what her father was telling her.

After a short period of silence, she asked her father again: "Father, before talking to you, please ask Rong Erchen to go back to the school palace and explain some things to his companions." ”

"Yes."

Xu Yan: "Eighth sister, our car is fast, the team behind us is not slow, and when they return to Xianyang, I am afraid that they will be one or two hours later than us." ”

"You might as well listen to what your father wants to say to you first, and then it's not too late to go back and arrange the follow-up work."

Ying Zheng slapped his forehead: "That's right, my father ignored such an important matter." ”

"Father, what do you want to tell the eighth sister? Why not tell me now? ”

Yin Yan listened to the communication between her father and the two imperial sisters, and there was always a feeling of emptiness in her heart.

As the eighth and ninth sisters made more and more contributions, Yin Yan felt more and more worthless.

She thought she was full of love for music, but in the past few months since she went on tour with her father and the emperor, Yin Yan found that her so-called love was just singing.

I really don't have a talent for creation.

But she held her breath again, and she had to create a catchy rhythm.

The more this is the case, the more irritable Yin Yan's heart becomes, and the more unsatisfactory the result is.

Now I hear my father and the two royal sisters talking so devotedly, I completely forget that there is a yang zi in the car.

She couldn't help but ask something she shouldn't have asked.

Yin Yan's words made Xu Yan frown slightly, and habitually looked up at the rearview mirror, wanting to observe the change in the little girl's expression in this way.

As a result, when I looked up, I found that there was no such preparation on Daqin's first car.

Before she could say anything, she heard her father's voice coming: "What are you doing when you little girl listen to so much?" ”

"What my father told your eighth sister was not ready for you and your ninth sister to hear."

Perhaps seeing the change in the little girl's eyes, Ying Zheng added nine girls when he said the back.

Sure enough, as he said this, the mood of Yin Yan, who was still a little lost, instantly cleared up.
