The autumn sun was still quite hot. When the two of them reached the foot of the mountain, they had already formed a thin layer of sweat on their bodies.

As we walked up the mountain, we were shaded by green trees and felt a lot cooler.

Yun Zhenzhen walked into the mountains and encountered many herbs along the way, such as aconite, dandelion, plantain, bitter herb, etc. Many of them can be used as medicine and as wild vegetables, so the amount seen is very small.

Many elders in Qinjia Village know how to identify herbs. Even if they have a headache or fever, they are reluctant to see a doctor. Instead, they find some herbs to eat and get over it.

"This is phoenix tail grass." Qin Li was walking and suddenly stopped in front of a grass.

"During the days I was away, I learned a lot of herbal medicine from the county magistrate's doctor. This can treat swelling caused by mosquito bites. The autumn harvest is coming soon, and there will be a lot of insects in the fields. Should we take some back?"

Yun Zhenzhen looked at the eldest brother in surprise. She didn't expect that the eldest brother was not good at studying, but he had some talent in this area.

"Sure, pick some and put them in your backpack to take back."

After picking them, the two continued walking along the mountain road. She vaguely remembered that the two Chinese herbal medicines were Xanthium sibiricum and Daphne koreana, and the two searched all over the mountain.

More than an hour later, Yun Zhenzhen returned with Qin Li with a full load.

In addition to Xanthium sibiricum and Daphne koreana, there are also various other Chinese herbal medicines in the backpack.

After returning home, Yun Zhenzhen busied herself with boiling water and making juice, and asked Qin Wen to write down the steps with a pen and paper.

Cook the two herbs separately and boil out the juice thoroughly.

Because she didn't know whether these two herbs were effective or which one was better, Yun Zhenzhen planned to do a small experiment.

"Ali, go to the wheat field and pick out thirty wheat plants that are diseased or infested with insects and separate them separately."

Qin Li was stunned for a moment, but still went out and did as he was told.

Yun Zhenzhen continued with the work in her hands, still thinking in her mind, two kinds of herbs, a control, and ten repetitions, the effect should be visible.

Qin Li obediently went to a corner of the field and quickly separated out thirty wheat plants, with each ten plants separated separately.

Half an hour later.

In the wheat field.

Yun Zhenzhen sprinkled the cooled potion on the surface of the wheat, used clean water as a control group, and asked Qin Wen to record it four times within twelve hours.

"Mom, what are you doing?" Qin Nan's eyes were full of curiosity.

Qin Wen and the other two behind him had already understood what was going on and explained to their sister, "Mother wants to see if these two herbs are effective for the wheat disease."

Qin Li also continued: "If we can really find herbs that can suppress the disease, then our crops will be saved."

Yun Zhenzhen gave the two of them an appreciative look and gave them a thumbs up.

After all, similar experiments have been done in modern times. As long as there is no data falsification, theoretically this experiment can be successfully carried out by oneself.

Now all we have to do is wait until tomorrow.

An aunt nearby saw Yun Zhenzhen and the others spraying something, so she came over to see what was going on.

"Hey, Miss Qin, what new thing are you spraying?"

"I'm just trying it out first." Yun Zhenzhen replied with a smile, "I don't know if it will work yet."

"Oh, this looks reliable. If it really works, our village will be saved." The aunt looked excited.

Yun Zhenzhen didn't want to say more and took the child back home.

sunset.

Classes have already started in the Yun family’s small courtyard.

Yun Zhenzhen was reviewing yesterday's homework and arithmetic with the children, but she didn't know that the rumor outside that she had found a drug that could prevent and treat diseases had spread like wildfire.

On the country road.

The village chief ran madly on the path.

dong dong dong-

Yun Zhenzhen turned around and saw the panting village chief.

"Qin Yun...Qin Yun, I heard...you found medicine...medicine?" The village chief was too tired to speak and sat down on the doorstep without caring about his image.

The orange sunset spread on the ground, reflecting the figure of the village chief. The evening breeze caressed the country courtyard, and the light reflected each other, making it beautiful like a painting.

Yun Zhenzhen quickly stood up and moved a stool to the village chief.

"Please calm down first."

The village chief took a few deep breaths, finally catching his breath, and then he couldn't wait to speak: "What they said is true. Have you really found a medicine to prevent and treat the disease? Don't lie to me, I will believe it."

Yun Zhenzhen said slowly: "Village Chief, please don't worry. We are still in the experimental stage and the results will not be available until tomorrow."

"What are the chances that you can prevent the disease?" The village chief looked at her tremblingly.

"Well...about 70% to 80%." Yun Zhenzhen hesitated for a moment and gave a more conservative figure.

The village chief's face was full of disbelief. He thought it was only 50% at most. He really didn't expect it.

Ever since he discovered the disease in the fields on the day he came back, he has been worried and couldn't sleep all night. Now suddenly he heard that Qin Yun had a way to cure the disease with such a high success rate. How could he not be excited?

"Okay, okay." The village chief said many good words in a row.

"We'll know the result tomorrow evening, and the village chief can come and take a look then." Yun Zhenzhen said with a smile.

After a few greetings, the village chief hurried back home. He had been very busy recently and was too busy to finish his work.

That night, the yard was brightly lit and several boys were staying up late to study.

Yun Zhenzhen looked at the eldest brother who was memorizing in the yard, and an idea came to her mind. Since he was interested in medicinal herbs, she could take him to buy some books related to medicinal herbs when she went out in a few days.

The most urgent thing is to let him recognize all the characters first.

the next day.

It's just dawn.

Qin Wen got up early and went to the field to observe the data, check the size of the lesions, measure them with a ruler, and record them in a book.

Record every two hours.

Yun Zhenzhen came to the old house.

"Mom, are you home?"

Old Mrs. Qin was mending shoe soles in the yard. When she heard a sound outside the door that sounded like the third son's wife, she quickly got up and went out to check.

"Third brother's wife, how come you have time to come here? Didn't you say you were busy with the illness? Is there anything you need help with?"

Yun Zhenzhen walked in and said with a smile: "It's not busy over there now. Awen is watching over it, so I came over to chat with you."

"Come in and sit down." Old Mrs. Qin led her to the table.

"Mom, I came here mainly to ask you about someone." Yun Zhenzhen said directly, "The surname is Chen, and the name is Bu Ya. She should be from Chenjia Village. I wonder if you have heard of this name."

Old Lady Qin has a wide range of social contacts, but they are limited to Qinjia Village, so she is naturally not aware of what is happening in other villages.

She thought that her second daughter-in-law was from Chenjia Village, so she called Chen who was working in the kitchen out.

After hearing what her third sister-in-law said, Chen said, "I've heard of this girl. She's from Chenjia Village. Her family lives at the entrance of Chenjia Village. When I married her, she was only five or six years old. Now she's grown into a big girl. Why are you asking about her, sister-in-law?"

"My eldest brother has taken a liking to her, so I came here to get to know her better." Yun Zhenzhen said with a smile, "If this girl has good character, I'll choose a suitable time to propose marriage and settle this matter."

When Old Mrs. Qin heard this, she was overjoyed. She had been thinking that her grandson was old enough and they could take care of each other first. Before she had time to remind him, she didn't expect that the third son's wife had already put it on the agenda.

The more I look at Yun Zhenzhen, the more I like her.

Chen on the side sneered.

Chen Buya knew that this girl was very ambitious. She looked down on ordinary people and always wanted to marry into a wealthy family. If she married into their family, it would be a lot of fun.
