"Sister is biased! Now that she has a master, she doesn't want Xiaoman anymore!" Xiaoman muttered, her eyes lingering on the plate of corn pancakes.

Sun Miao'er cut a piece and handed it to Xiaoman, smiling sweetly, "Eat slowly."

Xiaoman took a bite, her mouth trembling, and she stuck out her tongue, wanting to spit it out but unable to. "It's so hot! It's so hot!"

Sun Miao'er couldn't help but laugh at him, "I told you to eat slowly, and you still complained that your sister was being unfair. Now look what happened, your tongue is burned!"

"Hmph!" Xiaoman took another bite, not to be outdone. Her tongue burned with pain, and she even blew on it before biting.

Fu Yuchi ate two pieces, and seeing that Xiaoman was having trouble eating, he smiled and said, "I'll get you some medicine later. This pain will last for several days. After taking the medicine, you'll feel better today."

Actually, he was thinking that Xiaoman could endure the pain, but Xiaoman's cravings couldn't stand it. If she was in pain for several days and couldn't eat, he would probably feel terrible.

"What medicine is it, Master? It's so amazing!" This time it was Xiaoman who asked. He wasn't as interested in medicine as he was in food, but his strong thirst for knowledge made him curious about everything.

Fu Yuchi wiped the traces off his mouth with a fine linen cloth. "Why don't you and Miao'er come with me to the medicine hut? There are some herbs that need to be taken care of, and I'm afraid your sister won't be able to manage them all by herself."

Upon arriving at the medicine hut, Fu Yuchi opened the medicine cabinet, which contained rows of small porcelain bottles of various colors, none of which were labeled. Sun Miao'er was overwhelmed by the sight and guessed that only her master could distinguish them.

Fu Yuchi picked up the small, white porcelain bottle, poured out fine white powder, and instructed Xiaoman, "Stick out your tongue."

Xiaoman opened her mouth, revealing a burn ulcer on her tongue, which had turned white. It was both heartbreaking and somewhat amusing, that she had burned herself like this just to eat a bite of corn fritter.

Fu Yuchi sprinkled the white powder onto Xiaoman's tongue and said, "Hold it in your mouth for a while."

Suddenly, a cool sensation swept over him, and Xiaoman felt his entire mouth go numb with cold. The indescribable coolness did relieve the pain and even made his head clear.

"Much better, Master, but it's so cold..." Xiaoman's teeth were chattering from the cold as she forced out a few words.

Fu Yuchi shook the porcelain bottle in the light and plugged it with a cork. "It should be cool. How can it stop the pain if it's not cool?"

"Master, what kind of medicine is this?" Sun Miao'er naturally wanted to know what kind of magical prescription it was. Wouldn't it be a great benefit if she could learn it?

Fu Yuchi spoke calmly, "Watermelon Frost."

Sun Miao'er suddenly realized that this was the miraculous medicine, Watermelon Frost. She used to use Watermelon Frost often; she would spray some on it when she had toothaches, ulcers, or mouth ulcers. It worked incredibly fast, was icy cool, and basically healed completely by the next day.

I only knew that Watermelon Frost was a recipe passed down from the ancients, but I didn't expect it to have such a long history that it was already in use in this unknown dynasty.

Fu Yuchi saw through Sun Miao'er's eager eyes and directly saw through her thoughts, "What's wrong? Want to learn?"

"Yes, yes!" Sun Miao'er nodded eagerly. She not only wanted to learn, but she also wanted to promote this technology and mass-produce it.

Fu Yuchi had long since figured out her little scheme. "There's not much left, so I'll tell you how to make this medicine today."

Sun Miao'er started to get things organized, pulling her younger brother along, "Xiaoman, let's go get two watermelons."

Upon hearing about watermelon, Xiaoman became more excited than anyone else. Her mouth no longer hurt, and her teeth were no longer cold. She ran outside into the yard and shouted happily, "Sister, I know where there are watermelons!"

He had wanted to eat this watermelon for a long time, but his father, who guarded the watermelon patch, kept a close watch on it every day and wouldn't let anyone touch even the cracked watermelons in the field. He was really stingy. Xiaoman didn't have any copper coins in his pocket, so he could only watch others sit on the edge of the field and eat watermelons.

When they reached the edge of the melon field, Old Man Xie was lying in his thatched hut, hiding from the sun. Xiaoman walked up to him confidently this time, but before he could get close, Old Man Xie opened his eyes and yelled, "You little brat, go cool off somewhere else and don't bother me while I'm resting!"

Xiaoman angrily lifted the straw hat off Old Man Xie's head, pouting, "Old Man, I came to buy melons!"

"Two coins for ten catties, not sold individually." The old man waved his hand, seemingly not taking Xiaoman seriously at all.

Sun Miao'er took out two copper coins and slammed them on the table, saying, "Give my brother ten catties."

After saying that, she pointed and said, "Xiaoman, go ahead and pick whatever you like. I'll let you eat your fill today."

Old Man Xie really looks down on people. How can he bully Xiaoman just because he's a child?

Old Xie saw that it really was two copper coins, quickly stuffed them into his pocket, and said with a smile, "Girl, I was sorry for what I did to you, little brother. Go and choose! Hehehe!"

Sun Miao'er watched Xiaoman skip and hop into the melon patch, feeling secretly pleased. "Dad, let me make this clear: if these melons aren't good, you'll have to pay me back!"

Old Man Xie patted his chest and said, "Don't worry! Money back guarantee if it's not sweet! It's absolutely juicy and crunchy!"

In no time, Xiaoman came over carrying a big watermelon. After putting it down, she quickly picked up a smaller one. "Sister, I estimate this one weighs seven pounds, and this one should weigh three pounds. They'll be about the same weight!"

Old Xie glanced at the two melons, his eyes widening in surprise. "You little brat, you're not that old, but you're quite the expert at picking melons. You've got the two best ones of this batch!"

Xiaoman raised her head and looked at Sun Miaoer with a hint of pride, "Hehe, sister, I've seen them eating melons every day and I've figured it out. This kind of thing is guaranteed to taste good!"

Xiaoman carried a small watermelon, and Sun Miaoer carried a large watermelon; the siblings returned home laden with their bounty.

Upon arriving at the medicine hut, Sun Miao'er first drew a bucket of well water to soak the watermelon. Well water is warm in winter and cool in summer, making it perfect for cooling off on this day. After soaking for half an hour, the entire watermelon was thoroughly cooled.

"Eat the small ones, save the big ones." Fu Yuchi ground up the Glauber's salt, already prepared.

When Xiaoman (the 12th solar term) is cut open, the bright red flesh bursts out with tiny water droplets, the sweetness of the juice filling every inch of the surrounding land.

The same goes for Xiaogua.

Sun Miao'er picked up a slice, took a bite, and her mouth was filled with watermelon juice, sweet and refreshing, with a cool sensation from the bottom of a well. "Xiaoman, you have to teach your sister how to pick watermelons next time!"

"Hehe, sister, this is all based on experience. You wouldn't be able to learn it even if I taught you!"

Sun Miao'er tapped her younger brother on the head, "You've even learned to banter with your sister now? Trying to tease your older sister?"

"No way! My sister and I will eat half of this watermelon, and Master will eat the other half, like this..." Xiaoman mischievously bypassed Sun Miao'er and gestured with her hand towards the watermelon.

Although the courtyard of the medicine hut was not large, it was filled with the laughter of the siblings. Fu Yuchi had never felt lonely living alone before, but upon hearing these voices, a strange feeling suddenly arose in her heart, and everything before her eyes seemed unreal.
