That's why it's said that in ancient times, grain production was low and people often starved to death.

Just look at this barren and outdated agricultural technology and you'll know!

In fact, even in her original world, half a century before the explosion of modern technology, there were still famines that could cause millions of people to starve to death!

Liu Yingying personally supervised Lin Desheng and the others' work for several days, but she couldn't stand it anymore!

Because of the drought that has lasted for several months, even though there has been some rain now, the soil in the fields is still very firm.

Using oxen and camels as plows and other primitive farming tools was both strenuous and extremely slow!

Liu Yingying stood on the edge of the field, deep in thought for a long time, before finally speaking up and stopping Lin Desheng and the others.

"Brother Lin, why don't you all stop what you're doing for a moment?"

"Why?" Lin Desheng and the others were completely bewildered, wondering if Liu Yingying thought they weren't working hard enough.

"Sister Liu, we can go even faster..."

Liu Yingying realized they had misunderstood her meaning, so she quickly explained, "I didn't mean to complain that you were slow, but I think these farming tools are too outdated and affect efficiency!"

"Give me a few days, and I'll definitely modify these tools to be more efficient, so you can work more easily!"

Liu Yingying is the owner of these fields; they were just hired to work as laborers.

Seeing that she said that, Lin Desheng and the others naturally couldn't have any objections.

"Alright then... but Liu, are you sure you want to modify these tools?"

"This is no simple matter!"

Their ancestors have been using this farming method for thousands of years, and to this day, no one has been heard of having any good way to improve the efficiency of these tools.

Liu Yingying is, after all, a woman; she certainly wouldn't be able to do it!

"You guys go back and rest for a couple of days, and wait for my good news!" Liu Yingying said confidently.

Lin Desheng gave her a suspicious look, but ultimately left without saying anything more.

Liu Yingying rolled up her trousers and went down into the muddy field.

After carefully studying the curved plow and triangular seed drill used for tilling the land, I found that these tools were not much different from the traditional agricultural implements that have been passed down to later generations.

If an engine could be installed on these farm implements, the efficiency would definitely be doubled!

Liu Yingying is a decisive and efficient person. She immediately opened the store and looked for engine product information in the "unlocked" section.

"Found it!"

But then another problem arose.

She has enough points to easily redeem not only an engine, but also a complete set of agricultural planting and harvesting machinery.

But the problem is...

The concept of "technology" simply doesn't exist in the era she lives in.

How do I explain these things to others after I've redeemed them?

This problem troubled Liu Yingying so much that she couldn't eat or drink.

In the evening, Zhao Di prepared dinner and called her several times, but Liu Yingying didn't hear her. She locked herself in her room and buried herself in writing and drawing at her desk...

If the shape of the plow and seed drill could be slightly modified, for example, by adding a well-sealed and secure box to house the engine, it would be less likely to arouse suspicion...

"Liu Niang! Liu Niang, are you asleep?"

Zhao Di called her name several times from outside but received no response, so she couldn't help but start to worry.

"Oh, I'll be right out..." Liu Yingying finally heard the sounds from outside and walked out of the room.

Seeing Zhao Di's anxious expression, I couldn't help but feel puzzled.

"Silly girl, I'm just drawing up agricultural tools that need innovation. You can eat dinner first!"

"How can that be?" Zhao Di finally breathed a sigh of relief when she saw her come out.

"My father used to say, 'Food is as essential as iron,' so no matter how busy you are, you have to eat first!"

Liu Yingying smiled and sighed, "Alright then, let me see what delicious food our little Zhaodi has prepared for dinner!"

When she arrived at the dining table, she saw a plate of stir-fried sunflower leaves with meat, which Xue Ye had given her.

There was also a plate of bitter melon stir-fried with eggs.

Each of the three siblings had a bowl of brown rice in front of them, while Liu Yingying had a bowl of white rice in front of her.

"Why is my rice different from yours?" Liu Yingying looked at Zhao Di with a helpless expression.

Zhao Di: "Liu Niang, you're so busy every day, taking care of us three siblings and working in the fields, so naturally you need to eat well!"

"Yes, that's right!"

Although the Zhu brothers also wanted to eat white rice, this time they also felt that their older sister was right.

Liu Yingying shook her head helplessly, turned around and went to the kitchen to take out a clean rice bowl. She poured all four bowls of rice into it, mixed it well, and then served it to everyone again.

“Liu Niang…actually, we can really eat brown rice without any problems!” Zhao Di’s eyes welled up with tears.

What she said is true.

Compared to others who can't even afford brown rice, their family's life, with meat and eggs at almost every meal, is incredibly fortunate.

Actually, as long as she follows Liu Niang, she'd be happy even if she ate coarse rice for the rest of her life!

"Alright, the three of you are all at the age where you need to grow, so you must eat more. Otherwise, you'll all grow into short, stout people who won't be able to get married or find husbands. Do you expect your mother to support you for the rest of your lives?"

"Liu Niang!"

The three siblings felt a little embarrassed by what she said, so they stopped refusing and started eating.

Actually, Liu Yingying really didn't have much of an appetite at the moment. Her mind was full of thoughts about how to design something that was both reasonable and wouldn't affect the use of the tools.
