Go to ancient times and engage in construction

Zheng Yuming is very tired, but he is lying on the bed without feeling sleepy. He has come to this time and space for 20 days, and today he finally has contact with the society of this time and space. After getting in touch, Zheng Yuming misses the original time and space even more. Caring, there is a sister who misses you, a lovely niece, a wealthy family and a career, but when you come here, you not only have to face ancient people with different ideas and understandings, but also face the harsh natural environment. In the villa that came over, he, Chu Chaohui, and Mu Mu lived the best life without slashing and burning, eating wind and rain.

The more Zheng Yuming thought about it, the more he couldn't fall asleep, so he simply got up and put on his clothes, walked to the balcony of the villa to relax, opened the door, but saw that someone was already standing there on the balcony, and Chu Chaohui was leaning on the window sill of the balcony, smoking a cigarette.

"Would you like one?" Chu Zhaohui handed out the cigarette case to Zheng Yuming.

"Well, I'll have one too, can't you fall asleep?" Zheng Yuming took out a cigarette from the cigarette case, took Chu Chaohui's cigarette butt and lit his own.

"After knowing what kind of ghostly place this is, I can't sleep even if I want to." Chu Zhaohui took out another cigarette from the cigarette case and lit it, and pressed the butt of the cigarette against the blue brick on the window sill, making sure that the spark had been extinguished before throwing it away. Outside the courtyard wall, there is a virgin forest next to it, so you must pay attention to fire prevention.

"What do you do when you finish smoking the cigarettes?" Zheng Yuming is not an authentic smoker and has no addiction, but Chu Chaohui likes cigarettes quite a lot.

"Let's find a way. You always know how cigarettes are made. If you find tobacco in the future, you can make it yourself." Chu Zhaohui didn't seem to be in a hurry to stop smoking.

"You will?" Zheng Yuming raised his eyebrows.

"I know a lot!" Chu Chaohui showed his white teeth towards Zheng Yuming, "I'm not bragging at all."

"Oh, what do you know?" Zheng Yuming felt that what Chu Chaohui was best at was fighting. After all, Chu Zhaohui joined the Wa State Army when he was seventeen or eighteen years old, counting for more than ten years.

"Not to mention being proficient in using hot weapons, I can also make explosives, smelt steel, burn kilns, and make glass." Chu Zhaohui's skills in so many skills are all caused by the special local environment in Kokang.

"..." Zheng Yuming's cigarette was in his mouth and there was no movement for a long time.

"Aside from flowers and trees, what else are you good at?" Chu Zhaohui enjoyed Zheng Yuming's unexpected gaze.

"I seem to know how to farm." Zheng Yuming scratched his head. It seems that what he is good at is working with soil, but his major in university is not bad. He majored in mechanical design and manufacturing, and the whole waterwheel machinery seems to be fine.

"What we know is the basis for us to live and work in this world." Chu Zhaohui sighed towards the night sky. The Great Qin Dynasty existed in name only, and the princes of all parties were ready to move. Coupled with perennial natural disasters, the world will face turmoil.

"There are a lot of good things in my computer, so I saved them for fun when I was bored." Zheng Yuming suddenly remembered a big event.

"Stay bored and play?" Chu Zhaohui was puzzled.

Zheng Yuming patted his head embarrassedly at Chu Chaohui's doubts.Zheng Yuming likes to read novels, especially farming and the like. The most popular online novels are traveling to ancient times, using various modern technologies to develop their own strength, and then becoming kings and emperors.Purely out of interest, Zheng Yuming wanted to write an article himself. For this reason, when he was free at night, he collected a lot of information, covering all aspects of basic necessities of life.There are three major Fangmings that have not yet existed in this time and space, and there are production steps in the materials.After collecting a lot of information, Zheng Yuming was sent to this time and space before Zheng Yuming opened the hole.

"Unfortunately there is no electricity." Zheng Yuming sighed.

"No, we have electricity." Chu Chaohui stuck his head out of the balcony and looked at the off-road vehicle parked by the courtyard wall.

"That's right! Why did I forget about the Grand Cherokee?" Zheng Yuming patted his head and laughed. There is a cigarette lighter on the car, and the ground wire can be connected from there, and then the voltage can be changed through the voltage inverter, so that the computer and The printer works normally and can print out all the useful materials in the computer. With those materials, he may be able to live half of a modern life in his lifetime.

After the conversation on the balcony, Zheng Yuming and Chu Chaohui became more confident about how to live well in this society. Early the next morning, after breakfast, Zheng Yuming and Chu Chaohui started the Grand Cherokee SUV and turned it on. I fiddled with the cigarette lighter, used an inverter to change the voltage to 220V, and the computer and printer started to work.It took the two of them a day to print out all the useful things in the computer. When the computer data was filled to [-]/[-], the gasoline of the Grand Cherokee SUV was almost out, and the printing paper was also exhausted.The unfinished information on the computer is irrelevant, and the two of them don't feel a pity that they haven't printed it out.

The Grand Cherokee off-road vehicle without gasoline has since become completely useless. Although the off-road vehicle has become useless, it has played its best role, leaving some civilizations of the 21st century in this backward time and space.

"The making of this spinning jenny is the most useful." Chu Zhaohui couldn't stop nodding while looking at the printed materials.The invention of the Jenny machine was the beginning of the first industrial revolution in the previous time and space. Its appearance enabled the establishment of large-scale weaving factories.It was a British industrial revolution that affected the course of world history.In this time and space, even the flying shuttle has not been invented yet. After the spinning machine appears, the textile industry in this time and space will make leaps and bounds.

"I think papermaking is the most useful." Zheng Yuming knows what material paper is made of, but he doesn't know the specific steps. Now that it's done, with the papermaking step, it saves the need to explore and improve. It can be made into white paper at one time, and there is no need to go to the toilet in the future. I can't bear to wipe my ass with toilet paper.The toilet paper in the bathroom is gradually decreasing, and Zheng Yuming has considered using leaves instead.

"Why are there still primary and secondary school textbooks here?" Chu Zhaohui looked at Zheng Yuming with a little puzzlement. Could it be that Zheng Yuming wanted to be a teacher in this time and space.Zheng Yuming chose to print all the materials in the computer.

"We have to cultivate some talents for ourselves." Primary and secondary school textbooks are selectively printed, only Chinese, mathematics, physics, chemistry and geography are printed.

The primary and secondary school textbooks in the computer data were downloaded by Zheng Yuming's sister. She is a middle school teacher and took her daughter to spend the summer with her younger brother. Zheng Yuming didn't know the purpose of her sister's downloading these textbooks. , only to find that there were things downloaded by my sister in the hard disk of the computer.

After Zheng Yuming finished talking about his plan to cultivate talents, the two of them looked at the adopted brother and sister at the same time.

The two brothers and sisters now have names, the surnames are their own, and Zheng Yuming helped them choose the first name. The elder brother is called Huo Sizhong, and the younger sister is called Huo Sihua, which means missing China.

When Zheng Yuming and Chu Chaohui were busy printing the materials, the Huo brothers and sisters were trembling at first, frightened by the off-road vehicle engine, computer, and typewriter. After calming down, Huo Sizhong lingered to Zheng Yuming to find work, and was instructed by Zheng Yuming to look after Mu Mu and prevent Mu Mu from running outside the courtyard wall.As for Huo Sihua, he was instructed by Zheng Yuming to sit on the small bench and bask in the sun.

During the chat with the brothers and sisters of the Huo family, the two timetravelers got a general understanding of the life experiences of the brothers and sisters.The brothers and sisters lived at the junction of Wu and Wei. Due to the drought, the crops in the fields were not harvested. The parents of the Huo brothers and sisters left their homeland with their three children. They wanted to make a living in the south. There was a boy between Huo Sizhong and Huo Sihua. He died of illness while fleeing famine. Huo Sizhong was not seven or eight years old as he seemed, but was already 11 years old, and Huo Sihua was not five or six years old, but nine years old.

After the parents of Huo's brother and sister fled to Nanbu wharf with their two children, they both died of illness. Under the care of Nanbu villagers, the brothers and sister barely survived until now. The mouse that robbed them of food was the Huo family fleeing famine After meeting them on the way, for some reason, the mouse followed their family to Nanbu.

Huo Sizhong was wearing a sky blue padded jacket, a pair of black cotton trousers, and a pair of big padded shoes on his feet. He was staring at Mu Mu, fearing that Mu Mu would slip out from under the courtyard door in a blink of an eye.Huo Sihua squinted his eyes and sat on a small wooden bench. He was wearing a woolen jacket, a pair of down pants inside, and a pair of fluffy rabbit shoes on his feet.The clothes worn by the brothers and sisters, except for the sky-blue padded jackets that Zheng Yuming's old cousin's grandson left after playing in the villa, the rest were left by Zheng Yuming's niece. Zheng Yuming's niece was only seven years old, but she was much bigger than Huo Sizhong. Zheng Yuming's niece The black cotton trousers were worn on Huo Sizhong, and a trouser hem was long, while the clothes Huo Sihua wore changed from short to long, with the trousers rolled three times, and a pair of rabbit shoes were one-third bigger.

The clothes are so ill-fitting, but the brothers and sisters of the Huo family feel as if they are dying of happiness. After a while, Huo Sihua has to look at his brother and pinch himself hard on his thigh with his small hand to make sure that he is not dreaming.

On the second day after returning to the villa, the sweet potatoes, potatoes (potatoes), pumpkins found in the kitchen and the corn brought from the supermarket were planted by the two in the greenhouse.

Sweet potatoes are also called sweet potatoes. It is said that sweet potatoes were first cultivated by Indians and later introduced to the Philippines. In the 16th century, two Chinese who were doing business in the Philippines managed to weave some sweet potato vines into bamboo baskets and cables, and transported them back to their hometown in Fujian, where they were planted in China.The input of sweet potato is less, and the output is more.This year's planting is only to save the seeds. By next year, the root seeds harvested from more than a dozen sweet potatoes can be planted at least a dozen or twenty mu of land.

As for potatoes, although the name is called potatoes, they are not actually a local crop, but an out-and-out foreign product. Its other name is potato.It is a life-saving food discovered by Indians in the plight of starvation. However, the tubers of wild potatoes contain a large amount of solanine, which is poisonous to humans and animals. Many Indians who ate potatoes in the early days also paid the price of their lives. , The Indians have gone for thousands of years, and after a long and arduous domestication, from food to cultivation, they have cultivated potatoes with less toxins. In the 17th century, potatoes spread to China.This crop is also a high-yield food crop, with a higher annual yield than sweet potatoes, because it can be produced twice a year.

Sweet potatoes and potatoes are grown as root tubers, while squash are seeded as seedlings.The name of the pumpkin can tell that it is an imported product. It is native to southern Asia. It was introduced to the Central Plains very early, and it is called "rice melon" in many places.

As for the corn stuffed in the supermarket, it is even better. It is an annual grass herb, an important source of food crops and feed, and it is also the food crop with the highest total output in the world.This corn was discovered by Columbus in Cuba in 1492. After bringing corn back to Spain in 1494, it gradually spread to all parts of the world.By the end of the Ming Dynasty, corn had been planted in more than ten provinces in my country.

These four high-yield crops in the previous time and space will become the main grain of the valley in the future.These four crops native to the Americas arrived in the Great Qin Empire more than 1000 years in advance. More than 2000 years later, well-known scholars and experts on this blue planet have been arguing endlessly about the origins of these four crops. Below, these four crops are identified and may have grown in the Americas or Asia.
