"The sons and daughters visit their father, and their father is saintly. The courtier's sister met the princess's sister, Her Royal Highness Jin An. ”

Faced with the inquiries of her father and the ninth sister, Yin Yan did not answer in a hurry, but saluted solemnly first, and then said, "I'm helping the eighth sister." ”

"Father, Ninth Sister, come and see, Eighth Sister has come up with something particularly interesting."

Yin Yan hurriedly stepped forward and stretched out her hand to pull her father's big hand.

But when she raised her hand, she found that her little hands were stained with a lot of oil, and she hid her little hands in her sleeves, and her little face was a little embarrassed.

Seeing her like this, Ying Zheng stretched out her big hand to take the little girl's hand, and asked teasingly: "What?" Afraid of your father? ”

Yin Yan: "Father, the sons are not afraid, the sons are just ...... Just don't want to get your hands dirty. ”

"Okay, you are the daughter of your father, and your father doesn't dislike you for having dirty hands."

Ying Zheng laughed, the little girl in one hand and the nine girls in the other strode in the direction where Yin Yan came out.

Yin Yan and Xu Yan turned their heads to look at Zhen Yan: "Eighth sister, hurry up, we want to see the treasure you have researched." ”

Zhen Yan knew that the two younger sisters were worried that they would be jealous, so she couldn't cry and laugh and followed: "Don't worry, you eighth sister and I, so you won't be so stingy." ”

The monarchs and ministers quickly entered the experimental area and saw a strange-shaped object placed inside.

When she arrived, she could see its true face at a glance, and she was delighted: [Sure enough, it was the original appearance of the steam engine, and it was even better than the historical one. 】

[Presumably, this is the aesthetic formation of the eighth sister, which is more beautiful than the steam engine in the early stage of history. 】

[I just don't know if its internal settings have passed? 】

Ying Zheng listened to the voices of the nine daughters, and was also happy in her heart: she really deserves to be my daughter, and Zhen'er's aesthetics are so recognized by Xu'er.

He looked in the direction of the little girl: "What did Yangzi help your eighth sister?" ”

Yin Yan: "Father, the son helps the eighth sister add water to it, and then light a fire to boil the water, and add it in time when the water is about to boil." ”

Well, this is what she helped her eighth sister.

Zhen Yan smiled: "Not only that, but my little sister also helped me add oil to these gears so that the gears don't wear out too quickly." ”

"That's how the oil on her little face and hands came from."

"Ah, do I get my face dirty?"

Hearing the eighth sister's words, Yin Yan knew that her face was spent, and she hurriedly touched it with her backhand, but the stains on her hands were wiped on her face a little more.

"Poof."

Xu Yan finally couldn't hold back her laughter, "Hahaha......"

Ying Zheng also couldn't cry or laugh: "You girl, why did you forget that there are still dirty things on your hands?" ”

Obviously, I was embarrassed to come when I wanted to hold his hand before, but now I just wiped my little face.

Yin Yan: "Woo woo...... The ninth sister is bad, and she actually laughed at me. ”

But Xu Yan really couldn't stop for a while, she smiled and waved her hand: "No, no, no, no, no, hahaha......"

Zhen Yan was affected by the ninth sister, and she couldn't hold back her laughter, Ying Zheng forcibly comforted: "Don't be afraid, you are a glorious moment for laborers......"

Later, he really said that he would go down, and besides, the first emperor was going to break the defense.

"Hmph, you guys laugh, laugh, wait a minute, I don't add water, don't add oil, see what you can see."

After Yin Yan finished speaking, she couldn't help laughing, "Father and Emperor can endure it, just laugh if you want to, don't hold back." ”

"Ahem, ahem...... Father really didn't laugh at you. ”

Ying Zheng coughed a few times, suppressed the urge to laugh, and decisively changed the topic, "Okay, quickly get this thing out and test it for my father." ”
