As he spoke, Lin Tiandong lifted the bed board and removed a stone from under it, revealing a large hole inside. Those things were hidden inside.

Lin Ying felt much relieved. Lin Tiandong said, "Don't worry, during the winter I wore thick clothes underneath, so I wasn't cold during the day. I just took out the quilt and put it on at night. In the morning I put everything away. And all the food you gave me, I've kept it in here. This hole was dug for me by Huai Xiaozi."

Hearing her grandfather's words, Lin Ying knew that this place was not friendly to him. To put her mind at ease, Lin Ying insisted on taking Lin Tiandong's pulse. Only after confirming that her grandfather was alright did Lin Ying feel completely relieved.

“I didn’t know I would be seeing Grandpa today, otherwise I would have brought him some food from home.”

Lin Tiandong didn't care about any of that: "Let's not talk about that. I'm asking you, do you hate Grandpa for marrying you off to that brat Zhao Qinghuai without your consent?"

Lin Ying looked at her grandfather and shook her head: "I don't hate him. Grandpa knows me best. You know I've actually had feelings for him for a long time. It's just that I haven't said anything because I'm engaged."

Moreover, if it weren't for Zhao Qinghuai, I'd probably be dead by now.

Hearing Lin Ying say this, Lin Tiandong's worries finally eased: "That's good, that's good. When I heard Huai say that you didn't want to treat patients anymore, I was really sad. But when I found out that you got that frostbite ointment, I knew that you haven't changed."

As he spoke, Lin Tiandong became proud. She truly lived up to her reputation as his granddaughter; her medical expertise far surpassed his own.

It's not impossible for him to become a national medical expert in the future.

Hearing her grandfather say this, Lin Ying suddenly remembered something: "This prescription wasn't written by me; it was recorded in an ancient book I saw. Grandpa, I remember you mentioned before that our Lin family clinic has a head of household, right?"

Lin Tiandong was puzzled: "Why are you asking this? Our family separated from the main family back in my great-grandfather's generation. We have no relation to each other for a long time."

Lin Ying recounted what she had seen at the recycling station in the city: "Before the weather turned cold before the Lunar New Year, I was planning to buy some cotton quilts, but there was a shortage. I unexpectedly met a kind uncle who helped me find a few quilts at the recycling station."

Lin Tiandong nodded: "I know that, Huai told me about it back then. That quilt is nice, it looks like new cotton."

Lin Ying continued, "That's not what I meant. What I meant was that I saw piles of medical records and medical texts there. The medical records at that time were very similar to the way we recorded things in our family. That's where I saw the prescription."

Lin Tiandong looked thoughtful: "You mean, those things were all confiscated from the Lin family's main residence during a raid?"

Lin Ying also shared her guess: "I'm not sure either, but Grandpa said that only our Lin family keeps such records." Lin Ying kept the fact that she had found the jade pendant a secret.

She would never tell anyone about the jade pendant except herself.

Lin Tiandong sighed: "It's not impossible. After all, I heard that when the Eight Kingdoms attacked the imperial court, a large number of people fled here. Perhaps they came here back then."

After saying this, Lin Tiandong couldn't help but sigh, "Looking back now, they escaped the invasion back then, but they've suffered this time. However, we're too busy taking care of ourselves right now. Even if we knew how they are doing, what could we do? It would only be making trouble for ourselves."

Before leaving, Lin Ying wanted to leave some of the space well water for her grandfather, but she hadn't brought anything with her, so she couldn't explain where it came from or its effects. She had no choice but to give up.

Grandpa's health is still relatively good, and as long as there are no major setbacks, he should be fine. Lin Ying plans to go back and study the well water carefully, hoping to create some nourishing medicinal solutions.

Both Grandpa and Zhao Qinghuai should find it useful.
