Cheng Ling saw that it was still early, so she planned to meet someone.

She took the bus first, and then walked to this alley.

The alley was paved with green stone slabs, which were smooth after decades of wind, rain, and trampling. Maybe it was because of the rain last night, many green sprouts emerged from the cracks of the wall.

Cheng Ling went into the tavern to buy a jug of Daughter Red. Then, she took a few turns along the alley to reach her destination.

The destination was an old house that had long not been repaired. Cheng Ling did not knock on the door, but pushed open the creaking old wooden door without asking permission.

The couplets on both sides of the wooden door were written by Cheng Ling. She had just stepped into the door when the voice of an old man was heard. It could be said that she had heard the voice before she saw him.

“Xiao Ling came to see me again?”

An old man with white hair walked out of the room. He looked kind and his beard was white. Although he looked old, he was in good health. He didn’t stoop at all, and his voice was strong and powerful.

“Old Man Wu, see what I have brought for you.” Cheng Ling raised the wine jar in her hand as if she was asking for credit.

“Aiyo, Daughter Red! How old is it?”

“50 years old!” Cheng Ling helped Wu Fang to sit down on the rattan chair in the courtyard.

The courtyard was square. A parasol tree was planted in it, and it was sprouting new buds.

“50 years old Daughter Red. Xiao Ling, you must have something to ask of me!” Wu Fang opened the red cork and smelled the mellow smell of the wine. He laughed happily.

Wu Fang was already 87 years old, so she usually did not allow him to drink too much. This time, she bought the wine because she had something to ask of him!

“Tell me, what kind of difficult and complicated disease you have encountered again? To have the illness that can defeat you, I’m afraid this person will not live long!”

Cheng Ling washed the green jade wine glass and filled Wu Fang’s glass with the wine. “It’s Qianji Powder.”

Wu Fang’s hand holding the wine glass actually trembled, and a few drops of the wine spilled.

“Qianji Powder? That person with Qianji Powder that I met 10 years ago, the poison only took three seconds before he bled out from his seven orifices and died.”

“Are you sure that that patient of yours was afflicted with Qianji Powder?”

Cheng Ling nodded. “That’s right. I would never forget that pulse after I encountered it once. Moreover…”

“If I’m not wrong, the drug that my patient is currently taking is the Dragon Pill Powder that your grandson concocted.”

Wu Li, the 13th generation descendant of a traditional Chinese medicine family, was the grandson of this old man, Wu Fang.

The Lu family must have been left with no choice back then because of this poison, so they looked for Wu Li to concoct such a prescription.

“I didn’t expect that I would be able to meet a second person who was poisoned by this poison in my lifetime. How is he now?”

“He’s quite normal. The poison is suppressed very well. I heard that he was saved seven years ago, and he has been taking Dragon Pill Powder ever since. Over the years, I have also researched this poison whenever I have the time, but I haven’t been able to find the last two medicines.”

“So you came to me?”

Cheng Ling was quick-witted and filled Wu Fang’s glass with wine again.

“Yeah, who asked you to be my master?” Cheng Ling sweetly acted coquettishly. Only when she was facing Wu Fang and Xie Ying would she reveal this side of herself.

“Hey, master leads the way, but cultivation depends on the person! Haven’t you heard of this saying before? Are you ‘out’ now?”

Cheng Ling: “…” Master was using English, so trendy.

“However, speaking of this poison, I really didn’t do much research. My old eyes are blurry! You little girl have been learning from me for so long, I’ve already taught you everything. This world is still the world of young people.”

“Master, you’re still young and strong. Actually, I came here this time because I want to borrow a book from you to read!” Cheng Ling finally told him her purpose.

Wu Fang glanced at Cheng Ling. “‘Hundred Herbs and Thousand Medicines’, right? I know what you are trying to do. Take it, it’s in the study.”

Cheng Ling’s eyes lit up. She ran to the study on the second floor and got the book.

This book was compiled by Wu Fang, and it was the only one in the world. Since Cheng Ling acknowledged Wu Fang as her master, she had been following Wu Fang around the mountains and got to know many plants.

There were some parts of the book that she had helped edit.

It was a book that had been written for nearly 60 years. Almost all the plants with medicinal value had been included in it. It could be considered a cultural treasure of the world.

After chatting with Wu Fang for a while, Old Man Wu invited Grandma Chen, who lived next door, to play mahjong at the senior center. He then quickly chased Cheng Ling away.

It was already past two o’clock in the afternoon when she returned to the villa.. She had not eaten since this morning and was starving.
