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

"I found this in the mountains last year. I wanted to keep it for myself, but now it seems more appropriate to give it to you." The old man handed the ginseng to Lin Yu, "Young man, this is a little gift from me, you must accept it."

Lin Yu looked at the ginseng and was shocked. This ginseng was at least several decades old and worth a lot of money. He waved his hand quickly: "Old man, this is too valuable. I can't take it."

"What's so valuable?" the old man said anxiously. "You saved my life. What's so valuable about this?"

Liu Ying was watching from the side, and she was also moved. She knew that such ginseng was priceless, but the old man's kindness was even more precious.

"How about this, old man?" Liu Ying stood up. "I'll buy this ginseng. How much do you think is a reasonable price?"

The old man was stunned for a moment, then shook his head: "Little girl, I want to give it to him, how can I ask for money?"

"Old man, we all understand your intentions, but this is indeed too expensive." Lin Yu also stood up. "If you really want to thank me, then let us buy it. This way we will feel more at ease."

After some refusal, the old man finally accepted the money, but the price was far lower than the market price.

"Besides this ginseng, I have quite a few other medicinal herbs here." The old man opened several other jars, which contained various herbs he had collected over the years. "If you need them, feel free to take them."

Lin Yu carefully examined these medicinal herbs and found that the old man's collection was all top-quality goods. Some of the medicinal herbs were even treasures that he had seen in books but had never seen in person.

"Old man, this is a treasure trove." Lin Yu couldn't help but admire.

"Haha, what treasure trove? It's just some mountain products." The old man laughed happily. "I can't use so much by myself, and it would be a waste to keep it. If you need it, I can sell it to you at a low price."

In this way, Lin Yu and Liu Ying bought some other medicinal herbs. The old man insisted on charging only the cost price and repeatedly told Lin Yu to come to him anytime if he needed anything.

As the sky gradually darkened, the three of them went down the mountain and returned to the city. On the way, Liu Ying couldn't help but ask: "Lin Yu, why didn't the Wang family come to cause trouble again today?"

Lin Yu thought for a moment: "Maybe they know they're in the wrong. But I don't think they'll let it go."

"What should we do then?" Liu Ying was a little worried.

"If the enemy comes, we will stop him; if the water comes, we will block it with earth." Lin Yu said lightly, "We are upright and honest, so why should we be afraid of them?"

It was already past eight in the evening when they returned to the Liu family's house. Seeing them return, Mrs. Liu hurried out to greet them.

"Ying'er, Doctor Lin, you're finally back. I've been worried all afternoon."

"Grandma, we're fine." Liu Ying helped the old lady sit down, "and there's good news."

She briefly recounted what had happened today, and Old Mrs. Liu nodded repeatedly.

"That's good, that's good." The old lady took Lin Yu's hand and said, "Doctor Lin, thank you so much."

Lin Yu struck while the iron was hot and re-diagnosed the old lady's pulse and prescribed a new prescription. With the newly purchased medicinal materials, the effect of this prescription should be better.

Sure enough, after just one dose of medicine, Mrs. Liu felt much better. The next morning, she was able to get out of bed and walk around on her own.

Seeing her grandmother's improvement, Liu Ying was so excited that she almost cried. She held Lin Yu's hand tightly: "Lin Yu, thank you, thank you so much."

Lin Yu looked at her rosy eyes, and his heart was warmed. Being able to help their grandparents, he felt that everything he did was worth it.

However, what surprised Lin Yu was that the Liu family did not mention a word about the Wang family's visit yesterday, as if nothing had happened.

Chapter 2 Undercurrent

For several consecutive days, Mrs. Liu's condition improved steadily. Lin Yu came for follow-up visits every day and adjusted the prescription. The Liu family's attitude towards him also became better and better, especially Liu Ying, who always looked at him with an indescribable emotion in her eyes.

That morning, Lin Yu had just finished taking the old lady's pulse and was about to leave when Liu Ying's father Liu Jianguo suddenly spoke.

"Doctor Lin, there is something I want to tell you." Liu Jianguo's expression was a little serious.

Lin Yu stopped and said, "Uncle Liu, please speak."

"A few people came yesterday, claiming to be from the Traditional Chinese Medicine Association. They asked about your situation." Liu Jianguo hesitated, "I have a feeling their intentions aren't entirely straightforward."

Lin Yu frowned slightly: "What did they ask?"

"They're mainly asking about your medical teacher, whether you have a medical license, and where you learned your medical skills." Liu Jianguo shook his head. "I think these people might be looking to cause trouble for you."

Liu Ying listened from the side, her expression becoming serious: "Could it be that someone from the Wang family is behind this?"

"It's very likely." Lin Yu nodded, but there was no worry on his face. "But it doesn't matter. I'm upright and I'm not afraid of them checking."

As she was speaking, Liu Ying's phone rang. She glanced at the caller ID and her face instantly turned grim.

"What's wrong?" Lin Yu asked.

"It's my friend who called. She said there was some negative news about you on the Internet." Liu Ying said as she answered the phone.

After hanging up the phone, Liu Ying immediately opened the mobile browser and searched for relevant information. Sure enough, on several medical forums, some posts questioning the source of Lin Yu's medical skills appeared.

"What do these posts say?" Lin Yu leaned over to take a look.

"They say you don't have a formal teacher or relevant qualifications, and they suspect you might have stolen your medical skills," Liu Ying said angrily. "Some also say you might have stolen the secret techniques of a medical family."

After reading these posts, Lin Yu couldn't help laughing: "These people have a very rich imagination. What secret medical skills? If the Wang family really has some powerful secrets, would Mr. Wang's illness require him to seek medical treatment everywhere?"

"But we can't go on like this," Liu Ying said worriedly, "If the rumors keep spreading, it will affect your reputation."

"Reputation?" Lin Yu waved his hand. "I don't rely on this to make a living, so what's there to worry about? Besides, gold will always shine, and those who are interested will see the truth sooner or later."

Liu Jianguo listened on the side, and admired Lin Yu's demeanor even more in his heart. If it were an ordinary person, facing such doubts, he would have been unable to sit still long ago.

Over the next few days, online controversy surrounding Lin Yu intensified. Some self-proclaimed renowned Chinese medicine practitioners began questioning the source of Lin Yu's medical expertise. The most active among them were clearly paid to do so.

These people claimed that it was impossible for a young man to master such advanced medical skills without the guidance of a famous teacher. They hinted that Lin Yu might have secretly learned the secrets of a traditional Chinese medicine family.
