"Ouch, my eighth sister, this problem was found out by my father, you come to ask me, is this a little disappointing to my father?"

In the face of the eighth sister's emotional intelligence, Xu Yan is still a little worried, [The eighth sister will not engage in research, so the emotional intelligence research will be lost. 】

[You didn't ask your father for advice in time, but came to me for advice. 】

Ying Zheng: "......" This kid, your father is so careful? Will you be angry with your eighth sister?

It's not that Zhen Yan really has no emotional intelligence, but she didn't react for a while.

After the ninth sister's reminder, she immediately looked at her father for help: "Father, which of these organs do you think the sons and ministers should set up under their feet?" ”

"Well, it depends on how your car is driven."

Ying Zheng originally wanted to tell the content of the nine girls' hearts, but after thinking about it carefully, he changed his mind again, and then personally took Zhen Yan into the cab to compare.

"You see, we all have two legs, and we have to use them."

"Of course, the feet are certainly not as flexible as the hands, so the mechanism operated under the feet is better and must be there if they are not used often."

With Ying Zheng's prompt, Zhen Yan and her R&D team flashed with joy in their eyes and began to discuss enthusiastically.

Xu Yan listened more and more like that, so she didn't go to join in the fun, but just listened silently with a smile.

It wasn't until Zu Long saw the smile of the ninth girl who was getting more and more satisfied that his old man immediately made a decision:

"Yes, I just tried it according to the idea you provided, and it's quite suitable."

Saying that, the old man also did the action on the spot.

Xu Yan: "Father, these mechanisms are quite squeamish, you don't need to step on them so hard, lest you step on them." ”

But he was laughing in his heart: [Hahaha...... Father doesn't think it takes a lot of effort to do this, does he? 】

[What else do you want this thing to do in that case?] But it's no wonder that my father, after all, it's the first time he's seen this kind of thing, and he doesn't understand the principle. 】

[Presumably, the eighth sister and these scientific researchers can understand what I mean, and they will work hard to save effort when designing. 】

Ying Zheng: "...... Father didn't try to show them, and now there are no such mechanisms in the car. ”

This kid either doesn't complain in his heart for a long time, or when he does, he doesn't like to hear it.

Forget it, the child didn't say it directly, which is already saving me face.

Who called that his most important child, spoiled.

Xu Yan didn't know that her inner complaints were all in her father's ears, and she saw that the problems were discussed, so she reminded: "Okay, okay, these will be improved in Xianyang." ”

"Eighth sister, you have driven dozens of kilometers to come, you must have worked hard, go back to the post station to rest, eat something and wash up."

"Yes, Zhen'er, take your companions into the post station to rest, and go back yesterday to make improvements."

Ying Zheng also remembered that the child drove so far here to pick them up, and it was really hard along the way, "Come on, prepare some food for Princess Yunxiang and them." ”

"Yui."

"Your Majesty (Father)."

Zhen Yan and her R&D team were hurriedly flattered and thanked His Majesty and His Royal Highness, "Your Royal Highness Xie, the students are not very tired. ”

……

Early in the morning of the second day, Yingzheng and his ministers got up early, washed and eaten, and then prepared to leave for Xianyang.

Zu Long wanted to try the feeling of this new car, so he instructed the nine daughters: "Xu'er, you come to drive, my father wants to try the speed of this called car." ”

Ying Zheng knew that no one present was as skilled at driving this kind of car as his nine daughters.

Even if the car developed by the eighth girl himself, he trusts the ninth girl the most.
