Little Sizi came to my house and became the family's darling, and Li Shimin got anxious.

Empress Zhangsun watched Li Shimin teach the children hand in hand, and a very gentle and satisfied smile appeared on her face.

This is true family bliss, just like any ordinary family, overjoyed over a novel little object.

After everyone had calmed down, Empress Zhangsun asked them to stay.

"Xiao Xun, it's getting late. You've helped us so much today, you absolutely must have a meal in the palace and try our imperial kitchen's cooking. You can't refuse."

Li Yinxun had no intention of leaving in a hurry, so when the Empress invited him, he readily agreed: "Then I shall respectfully accept your invitation."

Before everyone could move toward the main hall, a series of footsteps could be heard.

Li Yin looked back and saw that the group of ministers who had just dispersed had somehow returned.

This time, each of them carried a small box.

Changsun Wuji, who was walking at the front, stepped forward on behalf of everyone and handed over the wooden box he was carrying.

"Well... Sister, His Majesty just said that the carriages need to be exchanged for gold and silver. We old folks may not be as fashionable as the young people, but we still want to keep up with the times. I would appreciate it if you could help us get a few carriages for us in future generations with this small gift of silver."

As soon as he finished speaking, the ministers behind him followed suit, each handing a wooden box to Li Yinxun and chattering amongst themselves.

"I would also like one."

"Bring one for me too."

"This is the deposit. Is it enough?"

Li Yinxun looked at the small wooden box, casually opened one and glanced inside. Good heavens, there were gold bars neatly stacked inside, as well as several high-quality luminous pearls.

Her lips twitched. She couldn't refuse such kindness, especially since it was something Li Shimin had tacitly approved. If she refused again, these old ministers would probably be sleeping at the door tonight.

"Okay, okay, I'll bring some next time I come."

Upon hearing this, the ministers were overjoyed and withdrew with profuse thanks.

Just as things were getting lively, a deep engine roar sounded.

The truck slowly drove up and came to a steady stop in front of us.

Li Yinxun was somewhat surprised. She peeked into the empty passenger seat and asked in confusion.

"Where's Uncle Cheng? Why did you come back alone?"

Guo Qian got out of the car and said with a smile, "Uncle Cheng is worried about those sweet potato vines. He said he was afraid that the people in the palace would be clumsy and ruin them. He's staying at the Imperial Estate right now and insists on keeping an eye on them himself. I can't stop him."

"Well done, Zhijie," Li Shimin couldn't help but praise upon hearing this.

The group enjoyed a sumptuous imperial meal in the palace.

It must be said that the culinary skills of the Tang Dynasty Imperial Kitchen truly lived up to their reputation.

After a satisfying meal, it was already late.

Just as Li Yinxun was about to return to the modern world to rest, several princes and princesses, including Li Chengqian, Li Tai, Princess Yuzhang, and Princess Qinghe, shyly surrounded her again.

Each of them held a small wooden box in their hands. Although they were not as extravagant as the ministers, they were still filled with a lot of gold, silver and valuables. Their eyes were full of expectation as they whispered their requests.

"Auntie...we want one too."

"Okay, no problem. What color do you want? I'll pick it out for you when we get back."

While agreeing, Li Yinxun silently complained in her heart: At this rate, next time I'll have to move the entire 4S store from Hyundai to make enough to sell.

Because they had to go to Huangzhuang early the next morning to plant sweet potato seedlings on a large scale, the group didn't do much more that night.

Wash up and rest early to get enough rest.

The next morning, Li Yinxun, who usually loved to sleep in and wouldn't get out of bed until late morning, surprisingly got up very early today.

We arrived at the Tang Dynasty before eight o'clock.

A convoy slowly drove out, heading in a grand procession towards Huangzhuang in the suburbs.

At the very front was an off-road vehicle driven by Li Shimin, with Empress Zhangsun, Li Lizhi, and other female relatives sitting inside.

Behind them was a truck driven by Guo Qian, with Li Yinxun and the little princess in the passenger seat, and Li Chengqian, Li Tai, and Li Zhi in the back seat.

Although it was a bit crowded, it was the first time in their lives that they had ridden in a carriage without horses, and they were all so excited that their cheeks turned red.

Two enormous vehicles, unlike anything seen before, drove along the wide Zhuque Avenue in Chang'an, instantly igniting the entire city.

People along the way stopped to watch, stunned and speechless, some even thinking it was a divine beast descending to earth.

Fortunately, the Imperial Guards had already cleared the way in advance, holding hands to maintain order and preventing curious civilians from getting too close, thus preventing a stampede and congestion.

The convoy slowed down slightly as it reached the busiest part of the East Market.

The little princess, sitting in the truck cab, looked out at the dense crowd of people and, far from being afraid, was extremely excited.

Her inner bull suddenly burst forth, and she poked half of her little head out.

He waved and shouted enthusiastically to the stunned crowd on the roadside:

"Nihoo~ Nihoo~"

"This is my car, everyone's rich."

Li Yinxun blushed instantly, so embarrassed that she scratched her toes on the ground.

"Oh, my ancestors, come back quickly!"

He hurriedly pulled the little princess's head back, closed the window tightly, and said, "You can't stick your head out, it's not safe, understand?"

Li Chengqian, Li Tai, and Li Zhi were also dumbfounded.

The convoy, filled with laughter, finally arrived at Huangzhuang, a suburb of Huangzhuang.

Cheng Yaojin, who had been waiting there, was dressed in a coarse cloth outfit with rolled-up trousers and a straw hat on his head. He was directing a group of tenant farmers to work on the edge of the field.

Seeing the convoy approaching, he wiped his sweat and shouted in a loud voice:

"Here it comes!"

After everyone got off the carriage, Li Shimin didn't put on any airs of an emperor. He took off his outer robe and strode straight to the fields.

Guo Qian took out a large bundle of one hundred new curved plows that he had purchased yesterday from the cargo box.

Compared to the original straight-shaft plow of the Tang Dynasty, this curved-shaft plow was more flexible to operate and required less effort to turn, making it especially suitable for deep plowing.

"Brother-in-law, good seeds alone are not enough; we also need good farming tools. Let's demonstrate this curved plow to everyone today."

Just do it.

On the edge of the field, a strong old ox was harnessed to a curved plow.

Guo Qian was instructing an experienced farmer on how to operate the equipment.

The old farmer was initially skeptical, but when he gently held the plow handle and gave it a gentle push, the plow head cut into the soil as smoothly as cutting tofu.

"Hey, that's light and easy!"

The old farmer exclaimed in surprise and shouted, and the old ox steadily moved forward.

The turned-up soil rolled backward like waves, with even depth and fine fragments.

"Good heavens, this man and the ox could probably plow more than an acre of land in an hour!"

The old farmer stopped, touched the turned soil, and exclaimed with delight, "If we use this amazing tool, we can turn over all 1,000 mu of land in our royal estate in just half a month! We can sow several more crops!"

The surrounding tenant farmers watched with envy, each one eager to try it out immediately.

Li Shimin, who was watching from the sidelines, looked at the lively scene, but a trace of worry appeared between his brows, and he sighed softly.

"Although this curved plow saves effort, it still requires oxen to plow. My imperial estate can certainly afford to raise oxen, but what about the poor people all over the world? Ten households may not even have one ox. Without oxen, no matter how good this plow is, it is nothing more than a pile of scrap iron."

Yes, although the Tang Dynasty was prosperous, the common people at the bottom of society were still poor.

If they can't afford cattle, this magical artifact is out of their reach.

Upon hearing this, Guo Qian chuckled and shook his head.

"Brother-in-law, you're overthinking it. The original design of this curved plow was to adapt to various environments."

He walked to the plow and pointed to the traction hook in front of him.

"If there are no oxen, two families can work together, with the able-bodied men of each family pulling the plow and harrow. Although it is slower than ox-drawn plowing, it is still several times more efficient than our old-fashioned long straight-shaft plow. As long as people are willing to put in the effort, even poor people can afford it and use it well."

Upon hearing this, Li Shimin's eyes lit up. "Manpower can also be used?"

"Of course!" Guo Qian nodded firmly.

"Okay! Okay!"

Li Shimin laughed heartily, looking up at the sky.

"With both high-yield sweet potatoes and advanced technology, everyone, rich or poor, can benefit—this is truly beneficial to the country and its people!"
