Who understands? He traveled through time with a high-spec spatial ability.

After spending two days in the space, she felt much better. Qiao Jingjing left the space with a hot water bottle.

When she emerged from the space, it was still pitch black outside, and dawn had not yet broken. She silently took out several packs of sanitary napkins and overnight underwear, as well as ten pairs of women's underwear, intending to give these items to Lin.

Because she hadn't had her period, she had completely forgotten about it. But now, she suddenly realized that her mother, Lin, was still using a menstrual belt made of wood ash. She was filled with remorse, blaming herself for not remembering it sooner.

When Lin got up and was about to go to the stove to cook breakfast, Qiao Jingjing quickly pulled her into her room.

“Mother, I had my period yesterday. The powerful being gave me some menstrual products for use in the immortal realm. I kept some for myself, and you can take the rest,” Qiao Jingjing said softly.

Upon hearing this, Madam Lin immediately became anxious and asked with concern, "Silly child, why didn't you tell your mother you were menstruating? How are you feeling now? Is anything bothering you? Don't touch cold water these next few days, and remember to wear more clothes when you go out."

After giving her detailed instructions, Lin began to carefully examine the things Qiao Jingjing had handed her.

When she saw the snow-white, soft, and delicate sanitary napkin, she couldn't help but exclaim, "Wow, this thing is so white and soft! Such a fine material is only used for menstrual pads; it's truly not of this world."

Qiao Jingjing patiently taught Ms. Lin how to use these new menstrual products. She said that during the day, she could wear underwear and attach sanitary napkins to it; at night, she could choose to wear overnight pants so she could sleep soundly all night.

She knew that women in this era used menstrual belts that were repeatedly washed and reused. So she specifically instructed Lin that these were disposable items and should be burned after use.

"Dan Neng said he would send these things every two months, and told us to use them sparingly. He also said that if we don't take care of our periods properly, we can easily get sick. Don't be careless, Mom."

Madam Lin nodded to indicate that she understood, "Yes, Mother understands. Mother will put these things into the box now."

What Qiao Jingjing was particularly satisfied with about Lin was that she never dragged things out or spoiled anyone's fun.

Ms. Lin always accepted whatever her daughter gave her or asked her to do without hesitation, and she had unconditional trust in her daughter, never questioning her decisions.

Unlike other mothers, Ms. Lin never made decisions for Qiao Jingjing without her consent.

Whether it's a big or small matter, she always consults with Qiao Jingjing first, seeks her opinion, and then makes a decision together. This respectful and democratic attitude makes Qiao Jingjing feel very gratified.

After breakfast, Qiao Jingjing went to the village head's house.

He told him that Qiao Wanxing's house had been rented to a distant relative of Manager Yu. The village head also remembered the young man who came with Manager Yu on the day of Qiao's coming-of-age ceremony. He naturally wouldn't hold this against him.

After saying that, Qiao Jingjing got straight to the point: "Grandpa Village Head, it would be best if next year's seedling cultivation could be completed before the Qingming Festival. It should take about 20 days."

Before the seedlings were planted, everyone was in a free state.

“Grandpa Village Head, I have an idea.” Qiao Jingjing smiled and said, “Every family in the village has some empty land, right? We can use it to plant some things, such as sesame, peanuts, sweet potatoes, and so on.”

The village head stroked his chin. "Will this work?"

"Of course!" Qiao Jingjing said confidently. "I'll take care of the planting techniques, and each family can figure out the seeds and land themselves. Even if we only harvest 10%, it's better than nothing."

The village head nodded. "That's a good idea. But do you have any connections with the seeds? Sesame is very expensive; I heard it came from the Western Regions. Not everyone might know how to grow it."

"Let me think..." Qiao Jingjing's eyes lit up. "I'll ask Manager Yu. Maybe he can help."

Qiao Zhengxian smiled, and then Qiao Jingjing continued, "Grandpa Village Head, if you trust me, plant more peanuts, sesame seeds, and sweet potatoes next year. Your family has a lot of people, so clear out some wasteland and use wood ash and rotten leaves to nourish it; you can grow quite a lot of things that way."

Qiao Zhengxian's eyes widened. "Oh?"

Qiao Jingjing looked at him and said seriously, "These things are very useful. Peanuts and sesame seeds can be pressed for oil, and sweet potatoes can not only be used as a staple food, but also processed into other grains, such as vermicelli, dried sweet potatoes, starch, etc."

She paused, then continued, "These foods won't spoil in years of famine and can be stored for a long time. If there's a famine, we can use them as backup food. That way, even if there's a famine, no one will have to worry about going hungry."

He then went on to explain the benefits of peanut oil and sweet potato vermicelli, emphasizing their production volume and commercial value.

Qiao Zhengxian listened intently, a look of surprise spreading across his face. "This... I never thought peanuts could be pressed for oil! And sweet potatoes could be made into noodles!" He slapped his thigh and stood up excitedly. "Jingjing, you're so clever! Daba Village is so lucky to have you!"

Qiao Jingjing smiled slightly and said modestly, "I heard it from a learned person in the city. As long as we pay attention, we can always find a good way."

Qiao Zhengxian nodded repeatedly in agreement, "Yes, there's something to learn everywhere in life. As long as you're willing, you can always learn something new. Jingjing, you've taught me so much!"

Qiao Jingjing smiled and waved her hand, "Grandpa Village Head, you flatter me. I'm just offering some suggestions. I hope they will be helpful to our village."

Qiao Zhengxian looked at Qiao Jingjing with gratitude, his heart filled with satisfaction. This little girl, though young, possessed such a bright mind and extraordinary vision, which was truly admirable.

A bold idea suddenly popped into my head, but the timing isn't right now. Let's wait until after the first rice harvest next year to bring it up.

Qiao Jingjing only mentioned these things to the village head; she didn't reveal much else. After all, life is a journey that must be taken one step at a time, and while most of the villagers weren't inherently evil, they still had their human weaknesses.

Giving too much at once will inevitably lead to greed and selfishness.

Therefore, they shouldn't be given too much too easily. They need to cultivate the land themselves, and they need to pay for the seeds.

Only when they have invested enough money and effort will they truly appreciate the hard-won results. In doing so, they will understand that everything requires hard work to obtain, and cannot be easily acquired.

The problem now is that Daba Village has little land and few people. I wonder when Young Master Tan will give us the estate he promised. Should we just ask him directly?

Meanwhile, Tantai Zhou was also troubled by a problem.
