Han Du saw that the two of them really didn't know what Artemisia annua was, so he continued to ask: "Do you know about Artemisia annua?"
The two shook their heads again.
Well, originally Han Du planned to use Qinghao to help them quickly understand Artemisia annua. Now that he has never seen Artemisia annua, Han Du had to directly teach them what Artemisia annua is, so as not to have to explain it to him.
What is Artemisia annua once again.
After Han Du carefully introduced the characteristics of Artemisia annua, he said, "This thing is like a weed in the wild. It must be there. If you have time to look outside the city, you should be able to find it."
Zhu Biao and Lan Yu looked at each other and nodded at the same time. After listening to Han Du's description, they really recalled it. They seemed to have seen this Artemisia annua before, but they didn't pay attention to it.
Although Zhu Biao no longer had any doubts about Artemisia annua, he still had doubts about Han Du. "Is this Artemisia annua a medicine? If it is a medicine, then it should cooperate with the emperor and ministers to cure the disease. What's even more strange is that you don't
Instead of boiling medicine, do you need to soak it in strong alcohol?"
Han Du put down the chopsticks in his hand, smiled and explained to Zhu Biao: "Your Highness, it is better to believe in books than to have no books. Even if it is recorded in a medical book, it is not necessarily correct. Artemisia annua is different from other medicines.
, absolutely cannot be boiled with water. Once boiled, the medicinal effect will disappear completely. It is only useful to use strong alcohol to extract the medicinal effect."
Zhu Biao also heard mention of medical skills from the doctors at the imperial hospital. He also had only a limited understanding of medical skills, so he did not continue to study further. He casually said, "I didn't expect you to have such a deep understanding of medical skills."
"How do I know so much about medical skills? I don't know any medical skills at all. I just happened to see this secret recipe for treating dysentery in a miscellaneous book." Han Du did not dare to pretend that he knew medical skills, otherwise when the time comes
What should I do if my secret is exposed?
As for what he said just now, Han Du had to say it because he was worried about Lan Yu. Han Du couldn't control the swords, guns and arrows on the battlefield. But there are too many things in this world that can kill people, not just swords, guns and arrows.
Ya, it's common for an illness to kill someone. Han Du didn't want Lan Yu to go to Yunnan and fall down from dysentery instead of dying on the battlefield.
"Oh? I don't know which miscellaneous book you are reading. Can you lend it to Gu to read?" Zhu Biao said quietly.
When Han Du heard this, his tone was stagnant. What book? I can tell you that it is a book called Du Niang?
Han Du had no choice but to laugh dryly, trying to avoid the question, "It's been too long, I can't remember it anymore, I can't remember it."
"You can't remember such a good book?" Zhu Biao looked at Han Du with a smile and said, "It doesn't matter. Gu's East Palace contains all the books in the world. Why don't you help Gu look for it sometime? Maybe you can
Where did you find this book?"
When Han Du heard this, he suddenly felt that the Zhu Biao in front of him was not a kind and honest gentleman at all, but a smiling tiger with dazzling eyes and a white forehead. Also, how could a person as cunning and vicious as Lao Zhu choose someone who is harmless to humans and animals?
Want to be the heir? Zhu Biao was able to convince all the officials in the court, and it was definitely not just about kindness.
Just when Han Du was at a loss what to do, Lan Yu suddenly shouted: "What kind of messy books? Are you here to practice for us today, or are you here to find books? If you are here to practice for us, then drink.
No one should mention any more books."
Han Du saw Lan Yu making jokes at the right time and understood. He quickly picked up the wine glass and said, "I wish my brother a victory and a triumphant return. Drink."
After saying that, he drank the wine glass in one gulp. At this time, Han Du no longer thought about the idea of not getting drunk by Lan Yu. As long as he could escape today, it didn't matter if he got drunk.
Zhu Biao smiled and had a good drink with Han Du with Lan Yu, which was considered a practice for Lan Yu.
...
Three days later, the army set off.
Lan Yu followed Mu Ying on the expedition in the name of deputy general.
The Yuan Dynasty's power in Yunnan was just lingering. If the Ming Dynasty had not been able to free up its forces, Yunnan would have been defeated long ago. Therefore, both inside and outside the government were full of confidence in this southern expedition, and never thought that the southern expedition would be possible.
What variables.
Therefore, the army's departure this time was not as grand as Xu Da's last northern expedition.
However, although he did not bring the officials out, Lao Zhu still came to deliver it in person.
Han Du was naturally not qualified to send it off, but today his sworn brother was going on an expedition, so he would not say anything else if he came to see it off.
"On the battlefield, swords and guns have no eyes. Please take care of yourself, brother." After saying that, he took out two telescopes from his arms and handed them to Lan Yu.
Lan Yu had never seen anything like this before and asked in surprise, "What is this?"
"This is a telescope."
Feeling that this was the first time he heard this name, he knew that this must be something created by his eccentric and wise brother. He asked: "What is the use of this thing?"
"This is how this is used." Han Du stood aside and explained it to Lan Yu carefully.
Lan Yu heard that this iron tube could allow people to see further, and hesitantly followed Han Du's statement and put his eyes on the smaller hole.
"Ah!!!" A loud roar came out of Lan Yu's mouth, and at the same time his whole body shook violently.
Looking back, she saw Han Du looking at him with a smile. Lan Yu felt that she was not ready just now and showed timidity in front of Han Du. As if to prove that the person who exclaimed just now was not him, she looked at him again.
Looking through the telescope, I looked into the distance. Sure enough, I saw the scenery that was originally very far away, as if it were right in front of me.
In disbelief, I moved my eyes away and looked into the distance. Now the scenery returned to normal. Looking through the telescope again, the scenery was in front of me again.
"This, this is really amazing." Lan Yu was overjoyed.
"Yunnan has high mountains and dense forests. Although I don't understand land warfare, in such an environment, I still know that those places are the easiest to be ambushed. Therefore, I made this telescope so that my brother can detect the enemy in advance.
The enemy has the upper hand." Han Du explained with a smile.
Lan Yu knew the purpose of the telescope and couldn't put it down. She slapped Han Du on the shoulder with excitement. Han Du grinned in pain. "Good brother, you have really helped me a lot."
Lan Yu has been in battle for a long time, how could he not know that a place with high mountains and dense forests like Yunnan is the easiest place to be ambushed? When he learned that this time he was going to Yunnan, Lan Yu had been vigilant about this.
But being vigilant is one thing, and whether you will be ambushed is another.
