Oh, don't be reckless

A small plastic bottle made of white glue.

Looking at this thing, Sun Simiao was a little curious. He fiddled with the small bottle back and forth, and after a moment, he smiled awkwardly and asked, "Your Highness the King of Chu, how do you open this thing?"

Lin Shen took it casually, unscrewed the cap, and handed it over again.

A strange way to open it...

But very convenient.

Sun Simiao looked very serious.

He put his nose to the bottle mouth, carefully sniffed, and smelled a pungent odor, which he had never smelled before.

He cautiously poured out some liquid into the bottle cap.

This deep brown liquid also puzzled him. He couldn't figure out what ingredients were in it.

Thinking...

Sun Simiao was about to bring the potion to his mouth.

Lin Shen, seeing this, broke into a cold sweat, "Stop, wait!"

"Hey, don't drink it, that stuff is poisonous!"

He reached out and grabbed Sun Simiao's arm with great force, preventing him from making any further movements.

Sun Simiao was not as panicked as Lin Shen, and smiled gently, "Your Highness the King of Chu, don't panic. I just want to taste what this potion tastes like..."

Lin Shen stared at the bottle cap in Sun Simiao's hand and said sternly, "If you don't understand anything, just ask me directly. This thing was taken out by me, and I understand everything about it."

"Don't be so reckless. If you drink it, even if you don't die, you'll lose your skin. What are you doing, old man?"

Sun Simiao carefully poured the potion back into the bottle, looking thoughtful, "So, Your Highness the King of Chu, is that why you had them register when buying pesticides?"

Lin Shen nodded, "Yes, in case there are incidents of poisoning with pesticides, with such a list and handbook, it would be much easier to investigate."

Sun Simiao sighed, "Your Highness the King of Chu is indeed thoughtful!"

Lin Shen waved his hand, "Just average."

Sun Simiao frowned, pondered for a long time, and then asked, "Your Highness the King of Chu, I know it may not be appropriate to ask like this, but I'm very curious..."

"I've been practicing medicine for so many years, and I've researched thousands of herbs, but I haven't found any herbs that could effectively kill locusts... Can I ask for the formula of this potion?"

Lin Shen fell silent.

Sun Simiao hurriedly waved his hand, "If it's inconvenient, I won't force you, Your Highness the King of Chu."

Lin Shen shook his head and said softly, "It's not that I don't want to give you the formula, it's just that this thing, even if I tell you, you may not understand it. The ingredients inside are very complex."

The young Daoist on the side was quite dissatisfied and said loudly, "My master is a divine doctor! Among all the doctors in the world, he is the most powerful. There is nothing in the field of medicine that my master doesn't understand."

Sun Simiao gently patted the young Daoist's head, then said softly to Lin Shen, "Don't listen to my ignorant disciple's nonsense. I have been practicing medicine for many years, but I still feel insignificant. Perhaps I have just entered the medical path..."

The young Daoist snorted and turned his head away.

Lin Shen nodded approvingly, "You seem quite clear about yourself."

Sun Simiao was taken aback.

His words were just humble...

Why did it sound like a slap in the face, acknowledging it...

Lin Shen rubbed his chin and said softly, "Mr. Sun, let me ask you a question. What is the function of ginseng?"

Sun Simiao almost without hesitation said, "To treat deficiency of yin and yang, weak lung qi, and to treat men and women..."

He began to recite a long and sleepy speech.

After Sun Simiao finished speaking, Lin Shen asked again, "Do you know why ginseng has such effects?"

Sun Simiao was taken aback, unable to find the right words.

The young Daoist did not understand the meaning behind Lin Shen's question and said indignantly on the side, "Ginseng naturally possesses this effect from birth."

Lin Shen waved his hand and chuckled, "Let me phrase it differently. Which part of ginseng determines its effects?"

The young Daoist stopped talking and began to recall medical books with a serious expression.

Sun Simiao stood up and respectfully bowed to Lin Shen, "Please enlighten me, Your Highness the King of Chu."

He was very clear that he seemed to have touched upon something extraordinary.

Before this, he had never thought of such questions.

His intuition told him that what the King of Chu was about to say might bring about earth-shaking changes to the entire medical field in the Tang Dynasty.

"Please, please sit down!" Lin Shen waved his hand. "There's no need for such formalities."

Lin Shen spoke softly, "This thing is very complex. If I were to tell you, it would take three days and three nights to finish. I'll just summarize it briefly."

"In this world, all substances are actually composed of tiny particles."

"They manifest different forms through different arrangements, forming the substances we see."

"Take ginseng for example."

"It is composed of countless tiny particles, among which the important factor that determines ginseng's medical effects is a substance called ginsenoside."

"Guess how much of this substance accounts for the weight of a ginseng?"

Sun Simiao frowned, trying to digest what Lin Shen had said.

The words were straightforward but profound.

Just the statement "substances are composed of tiny particles" made him feel a bit overwhelmed.

After a long time, Sun Simiao tentatively replied, "Since ginseng can have such effects, this ginsenoside substance accounts for at least half of the weight?"

Lin Shen shook his head and raised four fingers.

"Forty percent?" Sun Simiao asked tentatively again.

Lin Shen shook his head again, "It's only four percent."

Hiss—

Sun Simiao couldn't help but gasp.

The substance that determines ginseng's medical value accounts for only four percent of the entire ginseng?

Doesn't that mean the remaining ninety-six percent is not as important for medical purposes?

Lin Shen continued, "There's a saying that goes, 'Talking about toxicity without considering dosage is a joke.'"

"Some things are harmless until they reach a certain level."

"The insecticide in your hand is like this."

"It is concentrated into this bottle of potion by extracting a substance called 'nicotine,' so it's not that I won't give you the formula. Even if I give you the formula, you don't have the ability to extract 'nicotine' right now."

Sun Simiao was no longer concerned about the insecticide.

He was now in a daze.

"So many years, I've been on the wrong path in my medical practice..."

After a long time, Sun Simiao sighed heavily, and the light in his eyes dimmed instantly.

Lin Shen waved his hand casually, "Hey, look at what you're saying. Your path hasn't actually been wrong, but you've only just entered the medical field."

"You're still at the most basic level of application."
