Chang'an is located in the north, and the main food crops in the north during this period were still wheat and millet. Wheat and millet are both drought-tolerant crops, so they are suitable for the climate of the north with little rainfall.

During this period, rice was mainly distributed in the southern Jiangsu and Zhejiang regions. If you want to grow rice in Dujia Village, you still need to have the necessary irrigation conditions.

Fortunately, there is a clear river running through the middle of Dujia Village, which provides good irrigation conditions for rice cultivation.

In Du Chengfeng's memory, it was not difficult to grow rice, but the northerners mainly focused on wheat, and the villagers rarely came into contact with rice planting, so it seemed that they could only teach it in person.

However, the first thing Du Chengfeng has to solve now is the survival of himself and his eldest brother, and the money in the system cannot be used to exchange for the current coins.

Grandpa just passed away, he asked his eldest brother Du Wen, all the belongings are only 700 yuan, which is still saved by grandpa for many years.

Although according to the current price level of the Tang Dynasty, the 700 yuan can still support for a period of time. But now that he is systematically around, he is destined to be a person who wants to build a great career.

Wealth is also a resource, and without continuous wealth support, making achievements is just empty talk.

People say that a penny is difficult for a hero, money is not omnipotent, but no money is impossible, this is a wise saying.

Now that the prestige system has not been opened, the system store has not been opened, and to earn wealth, you can only start from scratch on your own.

How do you earn your first pot of gold? Du Chengfeng began to conceive in his mind.

Suddenly, he had a flash of inspiration and shouted: "By the way, we can make wine, this is simple and easy to achieve, the most important thing is that wine is profitable, or a sustainable industry, and it is definitely the first choice to make money." Du Chengfeng patted his thigh, and he was instantly inspired.

The alcohol content of this period is actually not high, and it is lower than that of later beers, about a few degrees.

That's why there is a poem: You will have to drink 300 cups, and don't get tired of singing and drinking 100 cups. Although there is some exaggeration of poetry, it also reveals the fact that the alcohol content of the Tang Dynasty is very low.

It is said to be sake, but in fact, it is made by natural fermentation by adding some grains to koji.

And the color of the wine is very turbid, the color is similar to the current rice wine, people are used to call this wine turbidity.

It was not until the Song Dynasty that the emergence of the distilled liquor process put an end to the situation of this turbid liquor.

As a modern person who has traveled over, I am accustomed to a high degree of liquor of fifty or sixty degrees, and where can I stand this kind of turbid liquor of several degrees, I always feel that it tastes weird.

Do what you want, Du Chengfeng is a man of action. Because of the problem of the predecessor's wooden personality, he didn't have much to do with the people in the village, and he had to find someone to help with this matter.

Thinking of this, Du Chengfeng hurriedly called his eldest brother Du Wen and ran towards Grandpa Du's house next door.

Grandpa Du was staggering for a walk in his yard, watching Du Chengfeng and Du Wen running over in a hurry, with a puzzled look on his kind face.

With doubts, Grandpa Du asked with great concern: "Chengfeng baby, what's wrong with the two of you, look at your hurried appearance, is something wrong?" ”

"Nothing happened, Grandpa Du rest assured, I just want to come to you to discuss some things." Du Chengfeng replied calmly.

"Oh, what's the matter, you say, Grandpa Du is old, if there is anything I can help with, just say it, don't be polite to grandpa." Grandpa Du breathed a sigh of relief and said with a relieved look on his face.

Grandpa Du's enthusiasm made Du Chengfeng, who had just come to Datang, a little uncomfortable. "Grandpa Du, is there any wine in our village, or ready-made turbid wine, the more the better, I urgently need it." Du Chengfeng asked tentatively.

"Wine! What do you want so much wine for? Grandpa Du's wrinkled face wrinkled, and he suddenly became nervous.

Looking at Grandpa Du's nervous appearance, it is estimated that he has misunderstood. Du Chengfeng hurriedly explained: "Grandpa Du, don't worry, I just want to buy some wine to do business." Now that my grandfather has passed away, I have to learn to be independent, and I can't just keep that broken house and do nothing, Grandpa Du, right? ”

Grandpa Du was stunned on his face, feeling that what Du Chengfeng said was quite reasonable, and he felt that Du Chengfeng seemed to be mature. Grandpa Du thought for a while and said, "Chengfeng baby, if you can think like this, Grandpa Du can rest assured." However, there is no brewing in our village, so if you really want it, you can ask your uncle and aunt to go to the village to buy some. ”

"Well, okay, can you trouble my uncle and aunt to help me buy some, as soon as possible, just buy it and send it to the house." Du Chengfeng said calmly. took out all his belongings and handed them to Grandpa Du, "Grandpa Du, this is all my belongings, and I will use them to buy the Turbid Bar!" ”

took out all the belongings left by his grandfather, Du Chengfeng had a bit of a desperate taste.

However, he did not have the slightest worry, based on his understanding of the historical process, he was confident that he could quickly accumulate enough capital in Datang.

"Riding the wind, what are you going to do?" Seeing that Du Chengfeng took out all his belongings, Grandpa Du suddenly couldn't make up his mind, and after looking at Du Chengfeng and then at Du Wen, he seemed a little worried.

Seeing the worry in Grandpa Du's eyes, Du Chengfeng sighed helplessly, he knew that Grandpa Du was worried about him, afraid that he was young and ignorant.

It's just that he doesn't know that the current Du Chengfeng's soul has become Du Chengfeng, a special soldier from modern times.

The manufacturing process of distilled liquor Du Chengfeng remembers very clearly, as long as the purchased turbid liquor is purified and processed, and then taken to Chang'an City to promote it, it is definitely a profitable business. Therefore, he was even more determined to purify the cloudy wine.

However, in order to reassure Grandpa Du, Du Chengfeng patted his chest and said, "Grandpa Du, you can rest assured, I just want to make wine, and I have confidence and certainty." Du Chengfeng's eyes flashed with determination.

Although he didn't know what Du Chengfeng did, seeing the confidence and firmness in his eyes, Grandpa Du finally chose to believe in Du Chengfeng.

In the past, Du Chengfeng was wooden, with few words, a quiet personality, and rarely communicated with people. It seems that after the blow of grandpa's death, a lot has changed, and the whole person is cheerful, and there is a vague and unruly temperament.

In Grandpa Du's opinion, Du Chengfeng's sudden change is that he has grown up and matured, which makes Grandpa Du very pleased, and his eyes looking at Du Chengfeng have softened a lot.

"In that case, then Grandpa Du will call your uncle and aunt to come out to help you." After Grandpa Du finished speaking, he led Du Chengfeng and walked slowly towards the house.
