Although he had fought with his wife many times last night and had a long chat, Guan Yi still woke up on time at the beginning of Chen Shi.

After washing up, he practiced Guan Dao in the small yard of the prefect's backyard. At this time, Qiao Qiang also got up. The couple used Gong Food. Then Qiao Qiang went to see her little tiger, and Guan Yi asked Guan Xiaoqi and more than a dozen servants who had grown up together to walk to the mountainside behind the prefect's house.

"I haven't been home for more than ten days. Is there any problem in the field?"

"Don't worry, the brothers took turns to be on duty these days. There were people squatting in the middle of the night. No one could get close except the birds in the sky."

"Well, what is buried in this piece of soil is enough to change the food dilemma of the Han Dynasty for thousands of years. It is impossible to be too careful."

The two were chatting, but a figure hurriedly ran over the mountainside. When they got closer, Guan Yi recognized him. This was another son of his Guan family, Guan Datou.

Everyone could see that Guan Datou's huge head was full of sweat on his forehead, and his expression on his face was extremely frightened. Guan Yi and Guan Xiaoqi couldn't help but feel nervous: "What's going on?"

"Seventh housekeeper, oh, the head of the family is here too. The head of the family, the green grass in your experimental field... When we got up this morning, we found that there were so many white flowers blooming..."

"Okay! It's blooming! Hahahahaha, big head, don't be nervous. This is a good thing!"

When he came to the experimental field and looked at the white flowers all over the ground, Guan Yi felt so comfortable. He counted one by one, yes, one hundred and twenty-five potato seedlings were growing well. More than 70 of them were blooming.

"Okay! OK! At most, you can harvest in another month! If you can do it faster this year, you will probably be able to sow a season!"

After the potatoes bloom on the ground, they will enter the rapid potato-bearing period. They usually last for 30 days. However, the premise is that the soil temperature cannot exceed 25 degrees. Otherwise, the underground potato pieces will stop developing. Thanks to the advantages of high mountains in Fuling County and the altitudes of more than one thousand meters in many places. The potatoes grown here generally can continue to grow for a long time. Therefore, the potatoes produced here are very fat. In fact, even in later generations, although the most famous potatoes in China are produced in Gansu, the entire mountainous areas of Yunnan, Guizhou, Sichuan and Chongqing are widely used in the mountains.

"Very good! Datou, you have taken good care of these potato seedlings! Xiaoqi, give each of them an extra hundred dollars!"

"Thank you, the head of the family!"

"Well, the next month is the key! We have to work hard for everyone to continue working. Apply farm fertilizer every five days to keep the soil moist and breathable... If a good harvest can be achieved in a month, I will never be stingy with the reward!"

"Abide by the orders of the head of the family!"

He stroked each potato seedling with nostalgia and satisfaction again. Guan Yi said to Guan Xiaoqi: "Go to the oil shop."

Rapeseed is native to Western Europe, and there is no such plant in Shu Han now. The oil mill mentioned by Guan Yi does not produce rapeseed oil for edibles, but tung oil for industrial production.

Speaking of which, the largest tung oil production area in China in later generations was Xiushan County, Chongqing. It happened to be in the current Fuling County. In fact, Guan Yi discovered that there were a lot of tung oil trees here shortly after he arrived in Fuling County.

Unfortunately, due to the limitations of the times, people of this era have not fully understood the role of tung oil trees. For those who have not solved the problem of food and clothing, is a thing of value very much? First of all, I would like to ask if this thing can be eaten? Although tung oil trees are about to bear fruit, the fruits are very toxic and cannot be eaten at all. Therefore, although tung oil trees are everywhere in the mountains of Fuling County, the locals have not used it effectively at all: taking it back as firewood and burning it is considered too much smoke!

When he came to the oil mill and smelled the unique scent of tung oil, Guan Yi was filled with golden light: This is all money!

"How much can be produced in a month now?" The head of the newly established Fuling County Oil Floor, also a servant of the Guan family, was called Guan Xiaoji.

"Report to the owner of the family. It is extremely labor-intensive to produce this oil, pick fruits, squeeze and filter. Currently, there are only about twenty people in the oil mill, so the output is not much. It only takes ten stones per month. If there are enough personnel, I guarantee that at least one hundred stones will be produced every month."

"How many people do you expect to achieve such a production?"

"Well, the head of the family needs about 200 people to pick and transport. Two shifts are arranged to press and make oil, each shift requires fifty people. Filtering requires fifty people. So at least three hundred and fifty people are needed."

"You have made a mistake in the calculation. It is important to know that if the scale is larger, the nearby tung trees will not be able to supply at all. Then you need to go to a farther place to collect the fruit. The transportation distance will be longer and the manpower will be insufficient."

"The family leader believes that the teaching is right. I don't think about it."

"Well, I will solve the problem of manpower sooner or later. How about the finished product produced? You must know that I have to sell it to have money to increase manpower for you."

"The head of the family, you have to say it carefully when talking about this slave." Guan Xiaoji changed into an excited expression: "This object is very magical. When brushed on the wooden board, it will soon dry. After it is dry, the wooden board is not water-permeable and reflective. The smell will sooner or later disappear. At this point, it is much better than paint. If this object can open up sales, my great man's paint will be squeezed out of sales by this object!"

"In addition to waterproofness, there is also the weapon maintenance mentioned by the owner of the family. Two months ago, we made the first batch of tung oil and then used it to brush a batch of gun tips. Then we buried it in the soil with the same number of gun tips without oil. A few days ago, we took it out and saw that the gun tip without oil was rusted, but the gun tip that had been brushed without oil was rusted at all!"

As an industrial raw material, tung oil has a wide range of applications. Unfortunately, Guan Yi is just a farmer student: he only knows how to plant and produce it, but the specific application of tung oil is not clear after it is produced. Even so, just two pieces of replacement of paint and brushing furniture and replacement of animal oil and lubricating oil and preservatives are enough to generate considerable profits.

The last stop is the pig house.

In such an era when no one can eat enough, except for the northern grasslands, most areas of China, animal husbandry is not very popular. Let’s raise livestock. This is not a vast grassland, but the Wuling Mountains with high mountains and dense forests. It takes a lot of manpower to take care of the livestock that are free of charge - otherwise the livestock that are free of charge will either be eaten by beasts or run away by themselves. If you say you don’t want to raise them, you will be kept in captivity. As the saying goes, people are not full and are busy finding food for themselves every day. How can you have the time and energy to find food for livestock?

In fact, it was very early to raise wild boars in China. At least in the oracle bone materials, there is a record that piglets must be castrated first. So after Guan Yi came to Fuling County, he saw the wild boars running all over the mountains and were very puzzled: Why don’t you catch piglets, and then carry them in captivity?

As a result, when Guan Yi asked this question, Ma Guo and a group of subordinates of the prefect's office were stunned: Why do you have to be castrated and then put them in captivity?

Well, although Ma Guo has a prominent background, his life is actually very hard because of Ma Su. Such a down-and-out young man, who is full of human energy, doesn't bother to learn and understand agricultural knowledge. Can you expect Pang Hong, who has completely inherited Pang Tong's arrogance, to know these "doomsday paths"?

When Guan Yi caught many piglets, except for leaving a few seemingly strong breeding pigs, all the other little boars were castrated and kept in captivity. Ma Guo actually expressed his opposition: People can't eat enough, so they still have to raise pigs?

So this is a question of concept. Pigs are full of treasures. Pork and internal organs can be eaten. They can provide people with more energy than rice, wheat, etc.

Bobble is the main raw material for all brushes. In the era of gunpowder, bobble is a strategic material.

Pig bones can effectively improve the general symptoms of insufficient bone calcification in people in this era, making children grow taller and stronger.

As for lard, it is the killer of all time travelers who have a little knowledge of chemistry: soap, candle, glycerin, all of them have to find a way out of lard!

Seeing the castrated piglets eating or sleeping hard in the pigpen, Guan Yi only felt that these castrated pigs were unprecedentedly cute. The fat pork, a lot of money and food exchanged from soap and candles...

"The head of the family, the brothers at the foot of the mountain, came to report that the head of the Mi family has arrived."
