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

Fortunately, there is a time difference in space, so there is still time to cultivate another 100 trays of seedlings in the next two days.

"Mother, are you sending some rice seedlings over to my uncle's house?"

Lin paused in her rice-cutting movements. "I'm very happy that you thought of my uncle's family. Let's skip it this year. Firstly, it's our first time doing this ourselves, and secondly, the journey is too far, and sending so many seedlings isn't practical. Let's wait until after this year's harvest and see how things go before deciding. We can prepare some rice seeds and send them over then."

Qiao Jingjing thought about it and realized that she was so focused on delivering the seedlings that she forgot about the transportation problem. Although she couldn't deliver the seedlings, she could visit her uncle's family in a while and bring them some other things.

Unsure if she'd have time to rebuild the house after the autumn harvest, she planned to install two heated brick beds (kang) before winter arrived. Although she had a temperature-controlled space, she still preferred the distinct seasons of the real world.

The purchased wasteland also needs to be cleared, but it's currently the busy farming season, and it's hard to find people. Once the harvest is over, most people will be idle at home, and hiring a dozen or so people to clear the land at the same time should be quick. Thinking about these things while working, time passed quickly.

It's 10 a.m., time to go home. The period from 10 a.m. to 3 p.m. is too hot, so people who work in the fields avoid this time.

The mother and daughter returned home, and Qiao Wanjun came back shortly after. After a simple lunch, Qiao Jingjing said to Qiao Wanjun, "Dad, let's go to Grandpa Village Head's house this afternoon." She was afraid that if her parents weren't there, she would have to explain herself quite a bit.

Judging by the time, it should be almost time for dinner, and besides, it would take time to walk there. The father and daughter walked silently towards the village head's house.

She came empty-handed today, but she brought such a great favor to the village. It wouldn't be right to ask her to bring gifts; they should be the ones thanking her in return. You must understand that grain is the foundation of a nation in any era, and it's the most important thing to do. Increasing the yield by 100 jin per mu (unit of land area) can save several lives, not to mention that her method could increase the yield per mu by several times compared to current yields.

The father and daughter were lucky; the village head happened to be home. Qiao Zhengxian, who had just finished lunch and was planning to take a nap, heard that Qiao Wanjun had brought Qiao Daya to see him. He put on his shoes and went to the main room, thinking to himself, "Are they here to buy land again?"

Qiao Jingjing politely greeted the village head, "Grandpa Village Head, hello. My father and I are disturbing your afternoon nap today because we have something we want to tell you. Right, Dad?" She glanced at Qiao Wanjun at the end. Qiao Wanjun wasn't good at handling these kinds of situations, so he nodded hesitantly, "Uncle, my daughter has some things to tell you about the fields. Please listen."

"Oh? That's strange. What does Da Ya want to say?" Qiao Zhengxian turned his gaze to Qiao Jingjing, wondering what this little girl wanted to say.

Qiao Jingjing didn't intend to beat around the bush and said simply and directly, "Grandpa Village Head, I have a way to increase our current rice yield by at least 100%."

As soon as she finished speaking, everyone in the main room except Qiao Wanjun gasped and stared incredulously at the petite girl in front of them. Did she even know what she was saying?

Qiao Zhengxian looked at Qiao Wanjun with a puzzled expression, but seeing that Qiao Wanjun's normal expression meant that he already knew and believed it. Then he looked at Da Ya, whose face was calm and composed. After all, she had been educated and served as a village head for several years, so she naturally had her own perspective.

"Da Ya, tell me, how exactly do you do it, and how did you know this method?"

Qiao Jingjing confidently said, "Grandpa Village Head, I recently discovered that all the rice paddies in our Daba Village have the same problem: uneven planting density. They're either too dense or too sparse." Qiao Jingjing explained clearly, "When the seedlings are too dense, the spacing between the rice plants is too small, resulting in poor air circulation, uneven sunlight exposure, and uneven nutrition for the rice, which in turn affects the yield."

The village head stroked his beard and nodded slightly in agreement.

Qiao Jingjing continued, "The solution is simple: appropriately thin out the planting and start seedling cultivation in advance. For example, if you originally planted 10,000 seedlings per acre, you can reduce it to 9,000. This ensures yield while saving seeds. Cultivating seedlings in advance before transplanting allows you to select healthy seedlings during transplanting, improving survival rates and extending the growing season. With these two methods, yield can be increased by at least 100%."

The village head's eyes lit up, as if he was considering the feasibility of this method.

The village head's eldest son, Qiao Wanxin, couldn't help but interject, "Da Ya, is this really going to work? What if production is reduced?"

Qiao Jingjing smiled and said confidently, "Uncle, don't worry. Actually, the principle is very simple. Too many seedlings crowding together are not good. Selected seedlings will grow better in a comfortable environment, and the survival rate will be higher."

"If Grandpa Village Head is still not at ease, you can come and watch when my family plants the second crop of rice in a couple of days. The seedlings have already been cultivated, and once my father has plowed the field, we can transplant the seedlings."

"What! We can plant autumn rice? Da Ya, are you sure you can do it?" The village head stood up excitedly, raising his voice.

"This is the second thing I want to tell you today. I have observed the climate and soil conditions in Daba Village, and it is entirely possible to grow two seasons. Of course, the premise is that seedlings need to be raised in advance, so that after the rice is harvested, the fields can be turned over and the rice seedlings can be transplanted immediately, shortening the waiting time for the rice seeds to develop. According to the rice's maturity period, it can be harvested before October, when it is not cold in Daba Village."

Hearing this, Qiao Zhengxian was deeply moved. What farmer didn't want to increase production? Who didn't want to have enough to eat every day? "Da Ya, quickly take me to see the rice seedlings you've cultivated."

Of course, there's no problem with that. Seeing is believing. Only by seeing the thriving rice seedlings with your own eyes can you believe that everything she said is reasonable and well-founded.

"Father, I'll go with you to take a look too." Qiao Wanxin stood up and walked outside with his father.

Qiao Wanhe returned home after using the outhouse and saw his elder brother and eldest daughter leading the village head and Wanxin in a hurry, not knowing where they were going. He went up to greet his elder brother and asked them what was going on. Seeing that the village head and the others were walking without stopping, his intuition told him that something very important must have happened, so he followed them to see.

Qiao Jingjing ignored her clever third uncle, but she didn't stop him either, since the whole village would know in a few days anyway.

As they approached home, Qiao Jingjing said to the village head with a smile, "Grandpa Village Head, there's a third thing Da Ya wants to tell you later. You'll have to go inside to find out."

Qiao Zhengxian was extremely anxious. He was eager to see the rice seedlings, and at the same time, he was even more curious about the third thing that Daya had mentioned. The increase in grain production and seedling cultivation had already shocked him enough, but was there anything more important than this?

Enough said, just hurry up and see.
