Some are measured in short timeframes, such as when winter is just around the corner. The first thing the people of Wengcheng need to do is keep warm. They usually buy cotton clothes and quilts from other places, but because they are poor, many people suffer from the cold every year.

Su Wanyan did know a method for this.

I once saw a wilderness survival program on modern television.

The people on the show heated a large rock, laid a mat on it, and slept on the rock to ward off the cold of the night.

In addition, heated pebbles can also be used to make roasted meat or pancakes.

Wengcheng is near Shishan, where there are many things to collect. Since it is still early winter, we can tell the people about this method and ask them to collect as many stones as possible. They don't need to be too big. After heating them up, we can put them under their mattresses. Perhaps they can get through this cold winter.

Everything written inside is what Su Wanyan can think of right now.

Yu Nanqing flipped through the pages one by one, her heart filled with surprise and inexplicable excitement. Her eyes widened in astonishment: "These... are all Yan'er's thoughts?"

While at the Prince's residence, Su Wanyan would spend some time every day arranging medicinal herbs. He thought Su Wanyan was only fascinated by medicine, but he didn't expect her to have such profound insights in these areas.

“It’s not all my own idea. I asked for other people’s opinions on many things, like this…” Su Wanyan reached out and turned to a page, pointing to it and saying, “Look, here, this is Huang Ye’s opinion. Wengcheng’s soil is barren, and she said that legumes are easier to grow.”

"Besides beans, there are also radishes and potatoes, which can all be grown here. However, the first step in planting is to clear the land. There aren't many farmers in Wengcheng; most of them are blacksmiths, carpenters, or hunters."

The local people knew this to some extent, but there were many external reasons why the harvest was not good every year, and she wrote them all down.

Besides consulting Huang Ye, she also asked Xiao Bu and Tanaka.

Because they had all traveled far and wide and had their own hometowns, they naturally knew more about this than Su Wanyan. They simplified the collected information, discarded the dross and kept the essence, and recorded it down.

Su Wanyan said, "Then you'll have to fight for three to five years to win the war, right? Besides, Donghai isn't some small country. Also, if Emperor Yuanhe doesn't summon you back, you'll have to stay on the frontier indefinitely. These plans of mine are still very necessary in the long run, aren't they?"

Of course, this also includes her expertise in saving lives. She has already chosen the location for the clinic and is just waiting for the day when she can open it openly and legitimately without having to hide in the shadows.

She might not be of much help with military matters, but she can certainly contribute to logistics.

Yu Nanqing suddenly looked at Su Wanyan with a curious expression: "Yan'er, how do you, a young lady from a humble background, know so much?"

Before Su Wanyan married into the Prince Gong's mansion, he was quite certain that she was just a young lady from a secluded family. Given her living environment in the Marquis of Yuanning's mansion, how could she have come into contact with these things?

What's more, Su Wanyan is only fourteen years old. Although he is reluctant to admit it, he is indeed ten years older than Su Wanyan. His life experience and knowledge should be richer than hers.

But he might not be able to make such a detailed plan as thoroughly as she could.

Thinking this through, Yu Nanqing couldn't help but look at Su Wanyan with a more inquisitive gaze: "I know Wanyan is clever, but where did she learn all this? Ah, it's Wanyan's medical skills..."

He seemed to only know that Su Wanyan was skilled in medicine, but he didn't know why her medical skills were so extraordinary.

Not only was Xiao Chensheng unable to cure him, but all the doctors he had seen said that there was no cure for him. So why was Su Wanyan able to cure him?

Yu Nanqing realized this too late; it seemed he had never delved into this aspect before. Everything was so natural that he had never even suspected anything.

Naturally, he has no doubts now; he is simply curious.

Su Wanyan burst out laughing: "Yu Nanqing, isn't it a bit too late for you to be worrying about this now? Is this the first day you've met me?"

Yu Nanqing was speechless. It was precisely because it wasn't the first time he had met Su Wanyan that he had doubts, since Su Wanyan seemed to have never contacted any other suspicious people besides him.

Hmm, Xiao Chensheng counts as one.

But Xiao Chensheng only appeared after his leg ailment had healed.

Seeing his furrowed brow, Su Wanyan didn't know how to answer. After thinking for a moment, she said, "Do you believe in the existence of innate wisdom?"

Yu Nanqing frowned as he looked at her, but didn't respond for a long time.

Seeing this, Su Wanyan knew he didn't believe her.

Naturally, they didn't believe it, and neither did Su Wanyan. After all, it was all made up by her, and even if it were true, it couldn't possibly happen to ordinary people like her.

However, this did not stop Su Wanyan from talking nonsense: "I think I am one of those people with exceptionally outstanding wisdom. I'm not bragging, but once I've read those medical books, I can basically remember all the knowledge points in the books and apply them to my own situations."

That's not a lie; that's exactly how she is now. The only difference is that after reading the book, she still needs to put it into practice before she can unlock the skills in the system.

As for other things, such as recording these problems and providing solutions, you can certainly learn those.

By visiting local people, consulting with knowledgeable individuals, and considering local conditions, geography, and a wide range of opinions, a feasible solution can be devised through compromise.

Of course, whether this method will work or not remains to be seen after it is implemented.

Life here is very different from modern life. Su Wanyan can learn from it, but she can't completely copy it. So what she wrote down were all plans she had imagined.

"Hmm." While Su Wanyan was rambling on, Yu Nanqing replied very seriously: "Yan'er is indeed outstanding."

The things she did to save Prince Gong's mansion and his life while his leg ailment was still unhealed are enough to prove it.

"I knew you would believe me." Su Wanyan smiled, feeling that no matter how outrageous her words were, Yu Nanqing would believe them without a doubt.

"Besides, people always improve. If you don't know something, you'll learn it after you learn it." Su Wanyan gave an example: "Take you for example. You learn from your mistakes. If Donghai tries to harm you again, will you fall for it? Don't you know how treacherous the court is? Once you've been wronged, are you going to be wronged again?"

Yu Nanqing will also learn from it, be vigilant, and take precautions in case of any unforeseen circumstances.

They just have different directions; in fact, they're doing the same things.

After Su Wanyan's rambling, Yu Nanqing's eyes brightened slightly: "Yan'er is right. I was so stupid that I was wondering why Yan'er knew so much. I've been in Wengcheng for several months now, and I just can't keep up with Yan'er's pace!"

"?" Su Wanyan was speechless: "This..."
