Mrs. Shang went back as usual, except for the personal maid Liu'er, no one knew what she had just ordered.

It just so happened that Lingbao and the others were also leaving, and Mrs. Shang reluctantly said, "Are you going to leave so soon? Stay a little longer?"

Ling Bao smiled shyly and said, "No, we still have something to do when we go back."

"Okay, I'll come back when I'm free, and I'm looking forward to your coming." Mrs. Shang smiled.

Lingbao nodded and said yes.

Sitting in the carriage, the three of them anxiously opened the agricultural book to find the introduction of farm tools, the other two were okay, they were used to riding in the carriage, but Lingbao was rarely like this, and they began to feel dizzy after staring for a while.

The other two were so engrossed in reading that they didn't even notice it.

The wheel of the carriage rolled into a stone, and the carriage flicked up slightly.

"Poof!"

Ling Bao bounced forward directly from the stool and lay on the ground like a little turtle.

Fortunately, Huaifu took into account the pampering of the prince and was reluctant to suffer without any harm, so he spread a thick blanket in the carriage, so Lingbao was not injured, but woke up the two people who were immersed in hard work.

"Lingbao! Are you alright?!"

"Lingbao !!"

The two of them hurriedly pulled her up, and Ling Bao sat on the stool in a daze, feeling that there were still words flying in front of her.

One brother looked at her palms, one brother looked at her knees, and Huaifu was also worried, but because of his identity, he didn't get started.

"Third brother, brother is fine, I'm fine." Ling Bao said with a big grin, "It's just a little dizzy to read a book in the carriage."

Xie Wuxian threw the book to Huaifu and said, "Go back and read it again!"

Cheng Jin didn't say anything.

It's just that on the way back, one hand grabbed Lingbao tightly, for fear that she would "fly" out again.

The purpose of the three of them was farm tools, so when they got home, they didn't look at anything else, but went straight to the part about farm tools and looked at it carefully.

They work together and see quickly, but it's useless.

Because the book only writes about the origin and usage of agricultural tools, it also talks about the structure, but it is very concise.

Xie Wuxian said, "It seems that this path is wrong."

"So what now?" Lingbao asked distressedly.

Cheng Jin held his chin and thought thoughtfully: "If we can't find the answer in the book, we can only figure it out by ourselves."

"How?" Ling Bao said casually, "Do you want to tear it down like the third brother you dismantle a toy?"

As soon as the words fell, Cheng Jin's eyes lit up.

Xie Wuxiao was surprised: "You really want to dismantle it?"

Cheng Jin hooked his lips and smiled: "Why not? Anyway, I'm confident that I can restore it."

Ling Bao and Xie Wuxian glanced at each other, and Ling Bao asked, "Will Daddy and Big Brother agree?"

As for whether the second brother will agree, it doesn't matter.

Xie Wuxian said, "We can buy a cocoon car for ourselves."

Why buy another one?

Lingbao thought about it, okay, she said, "Then we will each contribute some money. Hehe, I'm rich now!"

"How much money is there?" Xie Wuxian asked curiously.

"I won't tell you!" Lingbao stuck out his tongue mischievously, and said with his head in a way, "Daddy said, wealth is not exposed!"

Xie Wuxiao snorted: "I'm not an outsider."

Cheng Jin glanced at him, this person is really cheeky.

Xie Wuxian patted her head and said proudly, "How can you let the girl pay? I'll just buy it myself."

This Cheng Jin agrees, his sister's pocket money should be kept to buy beautiful clothes for herself.

Lingbao shook his head: "Don't, I want to go out together."

I can't help it, but I can only let her except for a small part.

The Xie family's guards were very fast, and they bought it the next day, and after seeing it, Cheng Yun knew that the three of them had discussed buying a cocoon, but when they saw it for the second time, the cocoon had been dismantled.

Cheng Yun: "......"

The three of them were demolished in the courtyard, so not only Cheng Yun and Cheng Yi, but many people in the village saw it.

"Oh my God, three little ancestors, what are you doing here?"

"This thing is so expensive that we bought one with frugality, why did you dismantle it?"

"Although it's not my family, my heart is throbbing!"

The seven aunts and eight aunts gathered in the courtyard, looking at the dismantled car with a distressed face, and kept wailing.

It is no exaggeration to say that they are not so distressed when their children are crying.

Lingbao couldn't find a chance to interject at all, so they could only obediently stand aside.

After a while, the aunts were less heartbroken and asked, "Boy, why are you dismantling it?"

Cheng Jin said, "I want to see how it is constructed."

Only by figuring out its structure can he construct it on its basis, otherwise his eyes will be blackened, and he himself will not have confidence.

I didn't know why I had to look at its structure, Han Xiaozhuang's mother, Xiao Zhou, asked, "Lingbao, don't you want to be a doctor? Are you going to change careers?"

"Not really." Ling Bao waved his hand again and again, and then pointed at Cheng Jin and said proudly, "My third brother said that he should figure out a multi-functional farm tool, dig a ditch and sow seeds, fertilize and cover the soil, anything!"

Speaking of farm tools, the big guy is interested.

Although I didn't know how to figure it out, everyone gave a thumbs up: "Good ambition!"

"Yes, yes, I think you will be able to do it!"

"We believe in you!"

The Lingbao family and the prince are the smartest of them, if anyone can, it must be them!

Looking at the dismantled car, although it is still very distressing, it is much better.

The pressure on the three of them doubled, immersed themselves in research, and even dreamed of how to improve the car.

"Ditching and sowing these two items, the columbus can be completed, the main thing is how to add fertilizer and cover soil." Xie Wuxian pointed out the problem.

The cocoon has been restored by Cheng Jin, and he is really talented in this area.

Ling Bao pointed to the cocoon and said, "The seed comes from here, why don't we also add a bucket?"

Cheng Jin nodded, adding it must be added.

"Add another stone tuo ...... behind the legs," Ling Bao vetoed himself as soon as he finished speaking, "No, no, that's too heavy."

What kind of improvement is that?,It's just just adding it directly.。

When the time comes, dragging Shi Tuo will be more tiring, that is, putting the cart before the horse.

"Isn't it possible to add a small mechanism or something to turn resistance into help?" Xie Wuxian touched his chin and asked.

Cheng Jin raised his eyes: "Do you have thoughts?"

Xie Wuxian spread his hands: "No, it's just an idea."

Cheng Jin: "......"

White was happy.

Lingbao was amused, laughing non-stop.

However, what Xie Wuxian said was a train of thought, Cheng Jin thought about it.

When he came back to his senses, he saw Lingbao staring at him, and Cheng Jin subconsciously touched his face: "What's wrong?"

Ling Bao sighed and said, "The third brother is much more cheerful."

When the third brother first came, he didn't talk much, and he only liked to be alone.

But now they're all rolling their eyes!
