After Zhaojiazhuang and Zhao Chuanyi took most of the people to Laoshan to open up the wasteland, only Langzhong Zhao Si's family and a few women took care of the children and livestock at home.

During this time, Zhao Si carefully studied the first ten volumes of "Qianjin Fang" obtained from Zhao Yuan, and felt that he had gained a lot. Zhao Si felt that in pediatrics, gynecology, etc., he had completely surpassed the level of the masters in the bazaar, and what he lacked was medical experience.

"Ruexiang, I'm going to go out to practice medicine, you can take care of it more at home." Zhao Si's wife Cai Yunxiang said.

After Zhao Si's son Zhao Chuanqiong went to study in the town, Zhao Si and his family were at home, and during this time, Zhao Si studied hard in retreat for more than a month, repeatedly studying the first ten volumes of "Qianjinfang" from Zhao Yuan, and also felt his own shortcomings.

"Daddy, are you leaving today?" Cai Yunxiang asked.

"Well, I'm going to go out and practice medicine for a while." Zhao Si nodded and said.

"Let's go tomorrow, I'll help you prepare clothes and dry food, uncle, they are all old mountains and wasteland." Cai Yunxiang said that Cai Yunxiang didn't feel strange that Zhao Si was going out to practice medicine, he had gone out before.

"It's okay, this time I'm going to go out for a little longer, and the family will work hard for you." Zhao Si thought for a while and said.

"How long are you going to go out, there's no problem at home." Cai Yunxiang asked, Zhao Si also went out to practice medicine in the past, but he came back in a month at most each time.

"It can be as short as three months, as long as half a year." Zhao Si said that what he learned from "A Thousand Golden Prescriptions" made Zhao Si very urgent for this medical trip.

"It's going to be so long, then I'll help you prepare what you need on the road." When Cai Yunxiang heard this, she was full of worries that her husband would go out for so long.

"Ruexiang, you don't know how much this book Atom gave me has helped me, after reading this book during this time, I feel more and more necessary to go out to practice medicine." Zhao Si said excitedly.

"Daddy, I'll help you prepare your clothes first." Hearing the tone of Zhao Si's words, Cai Yunxiang knew that it was very important for her husband to go out to practice medicine this time.

Zhao Yuan and Meng Ying made a regular lunch with the help of Wang Guihua and Feng Yulan, who had left work in advance, and after the villagers who helped with the work in the two villages had eaten, they continued to work in the field.

"It seems that the progress is very fast, and it will not be a few days before the ground is ready." After lunch, Zhao Yuan followed everyone to the field to check it out, and said with a smile.

"Don't worry, Zhao Dongjia, we people work, no one dares to be lazy." Hearing Zhao Yuan's words, Wen Jianglang said with a smile.

Zhao Yuan has such a large piece of land, it has to be cultivated every year, if someone is lazy this year, he will definitely not invite people from the two villages to work next year, Wen Jianglang can see this very clearly, and he will explain it to everyone thoroughly.

"Everyone is a real person, Uncle Lizheng is also too tired of others, don't drink cold water when you are thirsty at work, a big pot of boiling water has been boiled at home, and the water in the bucket will be added when it is finished." Zhao Yuan nodded and said.

"Okay, then we're done." Wen Jianglang said with a smile, picked up the hoe and started to work.

Zhao Yuan smiled, greeted the big guy who was working, and returned to the vegetable field, in the morning, the vegetable field only turned over a small piece, and the efficiency of the work was completely incomparable with the villagers of the two villages, Meng Ying was more neat than Zhao Yuan.

"Uncle, what kind of vegetables do I want to grow in my garden?" Luoluo took a small hoe and dug a small vegetable patch of his own.

"What does Luoluo want to plant?" Zhao Yuan asked with a smile.

"I don't know, but the vegetables I want to grow are different from those you grow, so that you can eat the vegetables I grow." Luoluo's face was stained with a lot of dirt, and he tilted his head and said to Zhao Yuan and the others.

"You'll have to think about it." Zhao Yuan said with a smile, the varieties of vegetables in this era are very single, and such a large vegetable field at home must be planted all that is suitable for the season.

"Uncle, you know so much, help me think about it." Luoluo said coquettishly.

"I do know of a vegetable called konjac, which no one has grown to eat in large quantities." Zhao Yuan thought about it and said with a smile.

Konjac, called konjac at this time, was not used for consumption, mainly as a medicinal use.

"Brother Yuan, you can't be talking about demon yoc, that thing is poisonous and can't be eaten." Meng Ying, who was on the side, heard Zhao Yuan's words and said.

"Yes, the konjac I'm talking about is also called demon yac, but I know how to deal with it, and this konjac tastes very good after processing." Zhao Yuan said with a smile.

Konjac is rich in nutrition, contains more than 10 kinds of amino acids, minerals and trace elements are also very rich in dietary fiber, although konjac is low in heat, low fat and low sugar is not very practical for people in this era, but it is indeed a very good food for satiety and good health.

However, the whole konjac plant is poisonous, and the tuber has the highest toxin, so it cannot be eaten raw, and it needs to be processed before it can be eaten.

"Since Brother Yuan knows how to deal with demon yoc, let's grow a little more, such a large field, and the demon yam can be scattered in the vegetable field." Meng Ying's eyes lit up and said with a smile.

"Auntie, I want to grow it alone." Luoluo heard Meng Ying's words, and they were going to plant a vegetable that the uncle had finally thought of.

"Luoluo, everyone grows the same dish, the important thing is not whether the vegetables you grow are the same as me and your uncle, as long as it is the vegetables you grow, we all like it." Meng Ying wiped the dirt on Luoluo's face with her cuffs and said with a smile.

"Okay, auntie, you can grow konjac." Luoluo said obediently.

"We've turned over such a large vegetable field, let's plant this piece of vegetable first." Zhao Yuan looked at Meng Ying and Luoluo and said with a smile.

"There are only some beans, spinach, woad seeds, and some green onions, ginger and garlic at home." Meng Ying said after thinking about it.

"Plant these first, and then go to the market in two days to buy some seeds for other vegetables." Zhao Yuan nodded and said.

Beans, spinach, green onions, ginger and garlic are sown in this season, and weed, that is, cabbage, can also be planted.

"Luoluo, do you know why such a small seed, after being planted in the ground, will grow into a vegetable that we can eat after a while?" Zhao Yuan raised the wall with a hoe, looked at Luoluo who was playing with a small hoe and asked.

"Why, uncle?" As soon as Zhao Yuan said this, Luoluo also asked curiously.

"Luoluo, do you know what happens when the seed is planted in the ground?"

"It will sprout." Luoluo said.

"It will still take root." Meng Ying also said.

"I know, uncle, if the seed eats the soil and water in the field, and then grows, just as we will grow after eating." Luoluo said happily.

"It's a little close, I'll talk to you about it later." Zhao Yuan said with a smile.
