Zhao Hao is not a doctor and has never studied medicine.

He didn't dare to make such an assertion about other diseases, but he was very clear about malaria. Because more than 400 years later, Tu Youyou won the Explosive Medicine Prize for discovering that artemisinin can cure malaria. At that time, there was a wave of artemisinin fever in the country, and Grandma Tu even wrote an article to popularize science, saying that artemisinin does not come from Artemisia annua, but is extracted from Artemisia annua.

Therefore, Artemisia annua cannot cure malaria, only Artemisia annua can. The Artemisia annua mentioned in Ge Hong's "Zuo Hou Fang" actually refers to Artemisia annua. It's just that these two plants belong to the same family and genus, and it's difficult for ordinary people to distinguish them. Even the "Compendium of Materia Medica" made a mistake. Therefore, doctors for thousands of years have mistaken Feng Jing for Ma Liang and have been using Artemisia annua to treat malaria, which of course can't cure it.

"What is Artemisia annua? How can it be used as medicine? Stop talking nonsense, young man!" The doctor was too lazy to talk any more with this boy who was pretending to make shocking remarks, and walked away in displeasure.

Zhao Hao shrugged helplessly. It seemed that it was impossible to make others believe him and bow down to him with just a few words.

The strong man did not send the doctor out, nor did he pay any attention to Zhao Hao. He just stood there silently, not knowing what he was thinking.

Zhao Hao was feeling embarrassed and didn't know what to say, but the burly man turned around and looked at him.

There was a deep knife wound on the right cheek of this man, and his face looked extremely ferocious with his pair of copper bell-like eyes.

Zhao Hao felt a little frightened when being stared at by the burly man, and began to regret having said too much.

"Hey young man, where are you from? Where did you hear the recipe from?" After a while, the strong man asked in a muffled voice.

"I'm a neighbor who just moved in later. This recipe was passed down by my elders." Zhao Hao answered without thinking, thinking, since I came from the future, all the wise men in the future are my dear family members. Grandma Tu is over 80 years old, so she is undoubtedly worthy of being an elder.

"So...what does Artemisia annua look like?"

Zhao Hao explained in detail: "It is exactly the same as Artemisia annua. You can't tell it apart from the outside. Especially in this season, when the Artemisia annua has just emerged, it is even harder to tell them apart."

"Are you trying to make fun of me, brother?!" The sturdy man frowned, and the scar on his face became more hideous.

"No, no, no, absolutely not!" Zhao Hao waved his hands repeatedly, not daring to keep him in suspense any longer, and said, "Pick a handful of leaves and rub them together. The ones that have no smell are Artemisia annua. The ones that smell bad are Artemisia vera."

"Is that so?" The strong man nodded and asked, "Then how should we consume it after we collect it?"

"Soak it in warm wine for a few hours, squeeze the juice and give it to the old man to take." Zhao Hao said, and then added guiltily: "But I'm not a doctor, this recipe is hearsay, don't hold too high hopes."

"Well, we have to try every possible way. Don't worry, young man, I won't blame you no matter what." The sturdy man was actually sensible and could hear Zhao Hao's worry.

This was exactly what Zhao Hao was waiting for, and he slipped away after saying it.

~~

When he got home, he remembered that he was so busy running that he forgot to ask to borrow a broom and dustpan.

"It's true that noble people forget things easily." Zhao Hao sighed secretly, and didn't want to face the fierce man again. Fortunately, although Caijia Lane was not prosperous, there were still a few vendors selling daily necessities.

He spent thirty cents to buy a broom and a bucket from an old woman, and also used his sweet words to get her to give him a few pieces of cloth to use as a rag.

After returning to the dilapidated yard, he first picked up a piece of the cleanest cloth and covered his mouth and nose with it as a mask. Then he waved a bamboo broom and swept all the dead branches and leaves on the ground into a pile in a corner of the yard.

As the dead branches and leaves were swept away, the bumpy yellow earth surface was exposed. What surprised Zhao Hao was that there was a well the size of a washbasin hidden in the southeast corner of the yard.

Zhao Hao picked up a stone and threw it into the well, and heard a slightly dull plop.

This made him so happy that he jumped out of the yard and ran to the street to buy a bundle of hemp rope.

He tied the bucket and went down into the well. Then he stood in a horse stance with both feet and used both hands to lift the heavy bucket up.

There was only half water in the bucket, and the other half was dead branches and leaves.

"It's so clean..." Zhao Hao was so moved that he almost cried. There were no plastic bags or mineral water bottles.

He poured the water in the bucket into the courtyard, then drew up a new bucket. He repeated this several times and finally drew up a bucket of crystal clear well water.

"call……"

Zhao Hao rubbed his almost broken waist with his arms which were too sore to lift, and he breathed a long sigh of relief.

After a short rest, he couldn't wait to scoop up a handful of well water and taste it. He found it sweet and refreshing, refreshing and refreshing.

"It feels so good!" Zhao Hao exclaimed in admiration. He washed his face happily with the well water and felt that the boredom of the past few days was finally gone.

With his spirits lifted, Zhao Hao continued to work hard to clean this place which he could temporarily call home.

He sprinkled water first and then scrubbed. While he was busy in the house, he was silently thinking.

This is not the life I want to live. This young master has traveled across four hundred years to experience the life of the poor in ancient times.

Even if you can no longer live a life of luxury, at least you should have everything you want, right? Otherwise, you would be too sorry for yourself and for the God who sent you here!

Zhao Hao stood on tiptoe, holding a broom, and rolled the spider web under the eaves into a gray cotton candy-like shape.

"If we want to turn the tide in this situation, the key is to make Mr. Zhao pass the imperial examination. From now until the autumn examination in August, everything must be based on this matter as the top priority."

Once the main contradiction is grasped, what to do next becomes clear.

'First, we need to create a good environment so that my father can prepare for the exam with peace of mind and not be distracted by anything. We also need to provide him with nutrition, such as milk, walnuts, dried fruits, and sea fish.'

Zhao Hao squatted on a stool that he had finally propped up, counting on his fingers for a while, and suddenly he let out a cry and cried out in sadness.

"What the hell is going on here? Who is the protagonist and who is the supporting role? Who is the father and who is the son?"

While crying, he continued to mutter and calculate: "Oh, there is one expense that cannot be saved. Mr. Zhao has to hold literary gatherings every now and then, and he may have to enroll in cram schools, which is also a large expense."

Because what Zhao Hao knew in advance was only the first question of the Four Books in the Yingtian County Examination.

Generally speaking, when people talk about the provincial examination questions or the metropolitan examination questions of a certain year, they often refer to the first question about the Four Books. Because the examiner always determines the general ranking of the candidates based on the quality of this eight-part essay. But the provincial examination has three exams after all. In addition to this first question, there are six more essays, as well as some theories, judgments, and current affairs strategies... Zhao Hao had never been involved in these before, and now he has to rely on Zhao Shouzheng's own ability.

Apart from the first topic, the rest of the article must at least have a coherent context and the views must be consistent with the court's direction, only then can it be accepted.

Therefore, it is absolutely not feasible to work behind closed doors. We must go out and bring in new ideas to liven up our thinking and write well. Even if it is the worst, we must make a name for ourselves among the current candidates.

You know, there is a crucial qualification exam before the provincial exam. You don't need to copy under a false name in that exam, you have to show your face in front of the old master!

If you don’t build up some reputation, who will know you?

~~

After much thought, Zhao Hao realized that the most important thing to solve was money! Money! Money!

To make money, Zhao Hao's biggest reliance is naturally his knowledge that is 400 years more than others. However, due to his current situation of being poor, he cannot do big jobs like making glass or soap. Other methods either require cultivating the market or requiring large investments. In short, no matter how hard he thinks, he can't come up with any zero-threshold, low-cost, and immediate way to make money...

"Well, let's be down-to-earth and go out for a walk some other day to see if there is a more realistic solution."

Zhao Hao had no choice but to put his thoughts aside and concentrate on cleaning.

Before he knew it, it was getting dark and he had just cleaned up the east room of the main hall where the father and son slept.

Seeing that he couldn't see the situation in the house clearly, Zhao Hao remembered that he hadn't bought oil lamps or candles. Just as he was about to go out, he heard Zhao Shouzheng's voice outside the door.

"Son, your father is back!"
