I am the Holy Poisoner, the Empress advised me to calm down

"No need." Xiao Yun waved his hand, his expression still calm. "If one comes, I'll kill one. If two come, I'll kill a pair. It's all the same."

Although the words were spoken lightly, Lin Shaoze could sense the murderous intent within them. His admiration for Xiao Yun increased even more.

"Brother, I'm truly impressed by your generosity." Lin Shaoze gave a thumbs-up. "But that Park Jung-yeol is indeed not an ordinary person. It's said that he can kill a cow with one punch."

"It's just a cow." Xiao Yun smiled faintly, "I've seen someone kill a tiger with just one slap."

Lin Shaoze swallowed his saliva and wondered who his elder brother was. He spoke these words as if they were true.

"Oh, big brother." Lin Shaoze remembered something, "I have indeed been restraining myself recently. I don't contact those bad friends anymore. It's just that sometimes I can't help it..."

"What can't you bear?"

"Even when I see a beautiful woman, I still think..." Lin Shaoze blushed, "Brother, is this normal?"

Xiao Yun glanced at him and said, "You can think about it, but if you continue to indulge yourself like before, you won't live past thirty."

"Ah?" Lin Shaoze's face turned pale in an instant, "Brother, you are not trying to scare me, are you?"

"Don't you know your own body?" Xiao Yun asked back, "Do you often sweat at night? Do you have back pain when you wake up in the morning? Also, look in the mirror and take a look at the dark circles under your eyes."

Lin Shaoze subconsciously touched his eyes, and there were indeed deep dark circles there.

"Brother, I know I was wrong." Lin Shaoze panicked, "I swear, from now on I will turn over a new leaf and become a new person. I will never touch those messy women again."

"Admitting one's mistakes and correcting them is the greatest virtue." Xiao Yun nodded. "Remember what you said today."

After seeing Lin Shaoze off, Xiao Yun returned to the backyard. Old Master Liu was sitting in a rattan chair basking in the sun, looking much better than he had in the past few days.

"Grandpa, how do you feel?" Xiao Yun walked over and naturally put his hand on the old man's wrist.

"Much better. My chest isn't stuffy anymore, and my legs and feet are stronger." Old Master Liu said with a smile, "Xiao Xiao, your medical skills are truly amazing."

Xiao Yun carefully felt the old man's pulse and frowned slightly. Although his condition had improved, the root of the disease had not been completely eliminated, and a stronger medicine was needed.

"Grandpa, I need to prescribe you a new medicine."

"Okay, tell me what medicine to use, and I'll ask Hong'er to buy it."

Xiao Yun wrote down the names of several herbs on a piece of paper and handed it to Liu Hong: "Follow this prescription and make sure each herb is top quality."

Liu Hong took the prescription and looked at the handwriting. Xiao Yun's handwriting was very good, with strong strokes, not like that of a young man.

"Brother Xiao, these herbs are quite common. I'll go to the Chinese medicine store right away."

Two hours later, Liu Hong returned with a large bag of medicinal herbs. Xiao Yun opened the bag and examined it one by one, his expression becoming increasingly grim.

"The quality of these herbs is too poor." Xiao Yun shook his head. "They are all cultivated artificially. Their efficacy is less than 30% of that of wild herbs."

"What should we do? Most of the medicinal herbs on the market are artificially cultivated." Liu Hong was a little embarrassed.

Xiao Yun pondered for a moment: "Is there any place where I can buy wild medicinal herbs?"

"There is a place." Liu Hong thought for a moment, "Two hundred kilometers from here, there's a Chinese herbal medicine market. They have everything there, including a lot of wild ones, but the prices are a bit higher."

"Price isn't the issue; the key is to get genuine goods at reasonable prices." Xiao Yun stood up. "Let's go there and take a look tomorrow."

"That's great." Liu Hong said happily, "I'm quite familiar with that place and can be your guide."

The next morning, Liu Hong drove Xiao Yun to the Chinese herbal medicine market. On the way, the two chatted about the market.

"That market is quite unique. There's all kinds of people there," Liu Hong said as he drove. "There are legitimate herbal medicine merchants, and some quack doctors. There are also some who specialize in buying wild herbs. Their products are really good, but they all have strange tempers."

"It doesn't matter, as long as the food is good."

Two hours later, they arrived at their destination, a large market built at the foot of a mountain. From afar, they could smell the mixed aroma of various medicinal herbs.

The market was bustling with people, a cacophony of dialects. Xiao Yun followed Liu Hong as they wandered between the stalls, carefully examining the various medicinal herbs.

"Sir, would you like to take a look at my century-old ginseng?" a stall owner greeted enthusiastically.

Xiao Yun walked over to take a look and shook his head: "It's artificially grown and not old enough."

"No way, this is wild ginseng dug out from Changbai Mountain." The stall owner was a little unconvinced.

"Look at these roots. The roots of cultivated ginseng are neat, while those of wild ginseng are messy and disorganized. And look at the texture..." Xiao Yun pointed at the lines on the ginseng. "The texture of wild ginseng is deep and dense, while yours is obviously cultivated."

The stall owner was stunned and speechless for a long time. The onlookers also nodded, thinking that this young man was indeed quite capable.

At this moment, a disdainful voice came from the crowd: "Hey, where did this young man come from, pretending to be an expert here?"

Xiao Yun turned around and saw a fat man in his fifties squeezing over with a mocking expression on his face.

"Hey little brother, you look so young, what do you know about medicinal herbs?" The fat man pointed at Xiao Yun, "Identifying ginseng is something as basic as that, and any apprentice can do it. If you're capable, come and see what I have."

As he spoke, the fat man took out a wooden box from his stall and opened it carefully. Inside the box lay a strangely shaped medicinal herb, completely black and emitting a faint fragrance.

People around gathered around and talked about it.

"What is this? I've never seen it before."

"It smells nice, it must be something good."

The fat man said proudly, "This is a thousand-year-old Polygonum multiflorum. I bought it from an old herbalist for 300,000 yuan. Little brother, if you can tell me the origin and efficacy of this thing, I will give you the stall."

Xiao Yun took a few steps closer and carefully examined the herb. After a moment, he smiled faintly.

"It's indeed Polygonum multiflorum, but it's not a thousand-year-old." Xiao Yun pointed at the lines on the surface of the herb. "A true thousand-year-old Polygonum multiflorum should have cracked skin and a unique luster. Yours is at most three hundred years old."

"Nonsense!" The fat man's face flushed and his neck thickened. "You are just a young boy, what do you know about thousand-year-old Polygonum multiflorum?"

"Don't believe it?" Xiao Yun took the Polygonum multiflorum from the fat man and gently broke off a small piece. "Look at this cross-section. The cross-section of a 300-year-old Polygonum multiflorum is brown with obvious ring-shaped textures. The cross-section of a 1,000-year-old Polygonum multiflorum should be dark purple, and..."

He paused, brought the Polygonum multiflorum to his nose and smelled it.

"And this taste is wrong. Real wild Polygonum multiflorum should have a special earthy smell. Yours is too
