I open a history tutorial class in Daming

Chapter 29: Only talking about Ming Dynasty is unfair to me
Just after Zhu Yuanzhang finished speaking, the mechanical voice rang in everyone's ears.

They had gradually become familiar with this and did not show any shock. Instead, they all clenched their fists, their hearts filled with indescribable excitement.

Liu Che and Zhu Qizhen, who had just arrived, were confused.

The latter didn't dare to ask anything, because although his ancestors were here, they obviously disliked him very much, and other people didn't look happy either, so he didn't dare to say a word.

The former could be asked to Zhang Liang, but unfortunately in the current situation, Liu Che knew that he had to be cautious in his words and actions and observe the situation, so he did not ask.

As fate would have it, neither of them asked Song Shen in person.

The other four first-generation students exchanged glances and basically decided to discuss the matter later, at least until the teacher didn't notice it, otherwise they would violate the rules set by this so-called "system".

After a moment.

Ying Zheng knocked on the table calmly, as if he remembered something, and looked at Song Shen.

"Sir, although you are giving a lecture, the things in the textbook seem to be quite old and have no reference value, let alone using the past to discuss the present. In addition to the things in the textbook, you also talked more about the Ming Dynasty, but did not mention much about the history between the Qin Dynasty and the Ming Dynasty."

"Isn't this a bit unfair? The Zhu family has benefited much more from this course than I and Liu Hou and the others."

"What's more, they have three people in one dynasty, the Han Dynasty has two, but I only have one. If you say that it's because they have many emperors and a long dynasty, then why don't they even have a minister of the Qin Dynasty? This is too isolating to me."

Song Shen scratched his head a little embarrassedly.

How can I explain this... Should I tell them that I was unlucky and had stinky hands, so I chose the worst emperor in the Ming Dynasty?

Before he could speak, Zhu Yuanzhang snorted coldly:
"Three? We don't even want the extra one. It's useless. It's a waste of space!"

Ying Zheng raised his eyebrows and said:
"From what you said, sir, Zhu Qizhen is indeed a useless and incompetent emperor, but he is the emperor of your Ming Dynasty and he is also from the future. No matter what, he will definitely try his best to help you. Even if he is useless, at least he understands the history of the future and can pass on his skills to you. Isn't that enough?"

Seeing that the two of them were about to quarrel again, Song Shen's head was buzzing.

He quickly raised his hand to stop her:
"Alright, alright, what are you guys arguing about? I've already told you that everything that needs to be covered will be covered in the textbooks!"

"Since classmate Ying Zheng feels that this is unfair, I will give you a few minutes to ask me three questions. Is that ok?"

Ying Zheng nodded immediately after achieving his goal, without saying too much and without asking for any further advantage.

After thinking for a moment, he asked:

"The first question is, when and where did I die, and why?"

Not a surprising question.

Song Shen did not hesitate and answered:
"In the 37th year of Qin Wang Zheng's reign, he died in Shaqiu Palace on his fifth eastern tour."

"As for the cause of your death, since the Qin Shi Huang Mausoleum was not excavated until more than 2,000 years after your death, no autopsy was performed, and there is no clear record in history books, we can only roughly determine that you died of illness."

"Later generations speculated that the main cause of your death was poisoning."

Not only did Ying Zheng's face turn dark, but the rest of the people were also shocked!

Zhang Liang and Zhu Biao said in unison:

"We haven't heard of such speculation!"

Ying Zheng also shook his head with a gloomy look:

"I can't say what will happen after my death, but I am confident that no one around me dared to poison me during my lifetime. Sir, is there any basis for what you said?"

Song Shen smiled. He spread his hands helplessly:

"Not all poisoning is intentional. Maybe people didn't even think it was poisonous."

"Student Ying Zheng, let me ask you, have you been taking pills for some time before entering the tutoring class?"

Ying Zheng was stunned for a moment, puzzled:
"That's true... But what does this have to do with the elixir? Before I take the elixir, I always arrange for palace servants to test it for poison. They had no problems after taking it, and neither did I. I even felt full of energy after taking it. How could it be poisonous?"

Song Shen raised his eyebrows.

He thought about how to explain the chemical problem to the ancients, and after some deliberation, he said:

"Here's the thing."

"It's not just you, classmate Ying Zheng. Other students who take elixirs are at risk of poisoning as well."

"First of all, let me ask you, do you know that cinnabar and mercury are poisonous?"

Ying Zheng and others nodded in unison.

Zhang Liang knew more about this kind of immortality-seeking and spiritual matters, and was better than Ying Zheng who just kept taking elixirs. He even quoted from the classics:
"The Classic of Internal Medicine says: Mercury tastes pungent and cold. It cures scabies, fistulas, scabs, ulcers, and baldness. It kills skin lice, induces abortion, removes heat, and kills poisons from gold, silver, copper, and tin. If melted, it turns into elixir. If taken for a long time, one can become an immortal. It is earth."

"Not only mercury, but gold, silver, copper and tin are all poisonous. However, if we use the fire in the elixir furnace to remove the toxicity, we can retain the nature of immortality. Anyone who knows something about elixir should know this."

Song Shen really laughed this time.

He didn't expect that, at least in the Qin and Han dynasties, the fact that mercury was poisonous was already common knowledge among people who took elixirs. As a result, they actually believed that the toxicity could be eliminated and continued to take it.

"Then let me tell you, no matter if it's mercury, cinnabar, or any other gold, silver, copper, or iron, after you throw it into the alchemy furnace to refine it, it will still be poisonous."

"It's just that the dosage of the pills is small and not taken every day, so the toxicity is not obvious. But after taking them for many years, these toxins accumulate in the body and cannot be excreted. Add to that the aging, slow metabolism, and organ failure, and you'll be damned if you don't die."

"Believe it or not, catch a chicken or a rabbit, stuff a few pills into it and feed it. It will die within a day. It's the same effect as a person swallowing mercury directly. These animals are small in weight, so if you increase the dosage, the erysipelas will take effect quickly."

"Okay, the first question has been answered. What about the other two, Mr. Ying Zheng?"

Ying Zheng:  …

He was in no mood to ask any more questions.

Now, he just wanted to return to Daqin as soon as possible and catch some rabbits or chickens to try out whether the elixir was really that poisonous.

If there really is one, he will cut those sorcerers into pieces one by one!!!
Ding-dong-

The get out of class bell rang at the right time.

Song Shen paused for only a brief second, and the smile on his face became much more sincere.

He clapped his hands and waved to everyone:
"Classmates, get out of class is over. If you still want to talk about what happened just now, I will give you ten minutes of free discussion time. The teacher will leave now. Bye, bye!"

Ying Zheng, Zhang Liang, Zhu Yuanzhang and Zhu Biao immediately raised Erkang's hands:

"Sir, when is the next exam..."

The words have not yet fallen.

Song Shen was already walking at full speed. He turned around, rushed into the office and started slacking off.

Yay, another day has passed!
