Charles Clark carefully pondered over each item, but when he saw the white fungus, he was stunned. It seemed he had caught onto something, and immediately called Lily aside to ask, “How long has Ethan been taking this white fungus medicine?”

Because Charles Clark was too anxious, Lily appeared a bit nervous and replied cautiously, “It should have started two months ago. Although this medicine never seems to improve Miss's condition, we dare not stop using it.”

Charles Clark's eyes lit up, and he let out a sigh of relief, saying, “I understand now.”

Yvonne Foster, standing by, asked, “Understand what?”

Charles Clark smiled and said, “I’ll tell you later. Lily, go quickly and fetch paper and brush. I’ll write a new prescription for you. Go to the pharmacy at once, get the medicine, and decoct it. Also... why is the scent of sandalwood so strong in this room? Your Miss is ill and needs ventilation. Open all the doors and windows, and remove all the incense burners.”

Poor air circulation might also be a reason for Ethan Foster’s worsening condition, but the real cause—Charles Clark had already found a clue. Just now, his brows had been deeply furrowed, but now he looked spirited and radiant as he took the brush from Lily, pressed down the white paper with a paperweight, dipped the brush in ink, and wrote out several medicinal ingredients.

Yvonne Foster, watching Charles Clark’s prescription from the side, couldn’t help but exclaim, “It doesn’t look much different from the previous one.”

Charles Clark finished writing and smiled, “A tiny error can lead to a huge difference. Many things can be caused by something seemingly insignificant. Just wait and see.”

Seeing Charles Clark’s confident demeanor, Yvonne Foster asked hopefully, “Brother-in-law, have you found a way to cure my sister?”

Charles Clark didn’t dare boast, but smiled slightly and said, “You’ll understand soon enough. I’m at least ninety percent sure.”

After urging Lily to fetch the medicine, Charles Clark sat back down by the bed, took Ethan Foster’s hand, and seeing her pale face, felt a pang of heartache. He gently held her wrist and checked her pulse again before letting out a sigh.

Yvonne Foster couldn’t help but say, “Brother-in-law, Lily is fetching and preparing the medicine. What should I do? I can’t just stand here, can I?”

Charles Clark thought for a moment and said, “Alright, I’ll give you a tough task. Do you see that copper basin over there?”

Yvonne Foster nodded eagerly, “I see it.”

Charles Clark smiled slightly, “Go, fill the copper basin with clean water, and stand under the eaves holding it high above your head.”

Yvonne Foster asked, “What’s the purpose of this?”

Charles Clark directed calmly, “Of course there’s a deeper meaning. Go on, don’t slack off.”

The more confident Charles Clark was, the more Yvonne Foster felt he could cure her sister. She grumbled a little but quickly followed Charles Clark’s instructions.

Next came the waiting. Charles Clark figured Ethan Foster wouldn’t wake up so soon, so he wandered over to the desk by the screen and flipped through a few books. These were all quite ordinary—some poetry collections and whimsical novels by Ming dynasty writers. A few thick volumes were the Four Books for Women. With nothing else to do, Charles Clark casually picked up a copy of “Precepts for Women.” This book, one of the Four Books for Women, wasn’t filled with the archaic language of the “Book of Documents” or the “Analects,” but rather with little stories, mostly about chaste and virtuous women of ancient times. Charles Clark read a passage: “Men value strength, women value gentleness. Regardless of right or wrong, women should unconditionally obey their husbands. Only with one strong and one gentle can harmony be achieved, and the bond of husband and wife be preserved forever.” He couldn’t help but smile, thinking: If women in later generations all read this kind of book, there would be no more overbearing mothers-in-law or unreasonable wives, and the world would be harmonious. But then he realized he was being biased from a man’s perspective. Some women in later generations may be unreasonable, but does that mean everything in “Precepts for Women” is right?

“Ethan is so gentle, she must have taken this passage as the ultimate truth, right?” Charles Clark secretly delighted in this thought, feeling a surge of masculine pride. Then his gaze fell on Yvonne Foster, who was under the eaves, struggling to hold the copper basin high above her head. The beautiful young girl stood tall and graceful. Charles Clark watched for a while, shook his head, and thought, “This book should be given to Yvonne to read more often. If only she would stop hitting people.”

Lily soon returned, panting, with the medicine, and immediately instructed the kitchen to start decocting it. During this time, the old madam sent a maid to inquire, and Charles Clark simply said he was working on a solution. By the afternoon, Ethan Foster had woken up. Charles Clark asked Lily to bring the medicine, took it in his own hands, cooled it with a spoon, and carefully fed it to Ethan Foster. Her body was weak, and in her daze, she saw her husband’s gentle care and looked at him with a hint of guilt, as if apologizing for her father’s troubles. Charles Clark saw through her feelings and, while gently feeding her the medicine, smiled and said, “It’s nice being a patient. In the future, I’ll have to fall seriously ill too, so Ethan will have to take care of me day and night.”

He spoke nonsense, making Ethan Foster smile, her eyes shining with a light she could not hide.

From outside, under the eaves, Yvonne Foster called out, “Brother-in-law, my arms are sore. I wish I could fall seriously ill too, so you’d have to hold a basin for me.”
