Fall In Love with the Technology Tree

    To be precise, it is the last day of the leap May.

    Whenever there is a leap month, Ah Sheng, who is used to the solar calendar, will feel uncomfortable with the current calendar. The sky is unbearably hot, the sun is shining brightly, and the cicadas are constantly chirping. However, according to the calculation of the lunar calendar, June has not officially come yet.

    It stands to reason that with such a high temperature, a lot of chickens in the chicken farms in the suburbs of Beijing should get sick and die. It was the first time to try intensive farming in ancient times, and there was no vaccine for chicken plague. Ah Sheng was already mentally prepared. But I don't know if it's because the chicken breeds today are different from those in later generations, or because the Newcastle disease virus has not been introduced into China, and the mortality rate is not as high as Ah Sheng expected. Even in dead chickens, the symptoms of death are not typical of chicken plague.

    A Sheng had to make gloves and masks and a simple version of protective clothing, and asked Liu to change and wash every day. Susceptible chicken breeds need to be eliminated, but at the same time retain enough genetic diversity in the flock to fight off unknown viruses in the future. Ah Sheng is a headache to calculate the genetic map, and I don't know how much the grass paper is wasted.

    Today's Cai Lun paper is yellow and brittle, and wood fibers of different thicknesses can be seen in the paper, which is disliked by the rich. If you want a whiter and softer paper, the cost will rise sharply. The bleaching process that relies on the ultraviolet rays in the sun will take the time calculated according to the year. However, Feitinghou's mansion bought shoddy yellow paper with rough edges. Except for the toilets for the masters, the rest were all drafted by Ah Sheng.

    No new sick chickens were found in the last days of Leap May, which made Ah Sheng relieved. The first batch of green beans has not yet come out. By next year, she will be able to feed chickens with mung beans, ginger, and a low-concentration potassium permanganate solution, which is said to prevent chicken plague. In the absence of a vaccine, native law is already the best way. However, she has to get potassium permanganate...emmmm, but unfortunately there is not even a Taoist temple in this era, and she has to find an alchemist.

    Everything is just getting started, everything is missing, everything is wanted.

    And Ah Sheng did not have a clear plan. She was born in the upper class, and she has no shortage of food, clothing, housing, and transportation. If she had been born into an ordinary family, she might have been eager to pick items that could be easily paid for, soap... or something. But she is a local tyrant, and the main contradiction in her life is the struggle between the house and the government, which is hard to say.

    A Sheng set his first core plan as raising chickens because of his maid Yan Wen. Her family was destroyed by a plague of locusts.

    According to Zhao Gou, locust plagues happen every few years. At this time, the court's solution to the locust plague was for officials to improve their moral standards! It is said that a locust plague broke out in Henan a few decades ago, and more than 20 counties failed to harvest any locusts, but there was not a single locust in M ​​County, which was surrounded by the disaster area. The results of the survey showed that because the magistrates of M County were virtuous and politically clear, they moved the heavens and kept M County away from natural disasters. Zhao Gou said that he was very yearning, and concluded at the end: "There must be traitors in the court, and natural disasters will continue in the heavy regions of Gyeonggi."

    Asheng...Asheng is powerless to complain.

    Raise chickens and raise an army of millions. In fact, the ability of raising ducks to control locusts is not weak, but because the farm that Cao Teng allocated to Ah Sheng is not near the water, it is more suitable to raise chickens in general. Just to supervise the chickens and prevent insects and theft, a few large white geese were mixed in the chickens. Ah Sheng occasionally feels guilty about these geese not being able to swim in the water, which is purely hypocritical.

    Ding was lying on a low couch under the shade of a tree. Her legs are now swollen, and she can no longer sit on her knees. Ah Sheng made several soft pillows with silk, propped up his mother's legs, and then pulled Cao Song hard to massage Ding's legs.

    "The mother is giving birth to the father for the father, of course the father will take care of her!"

    Cao Song felt novel and pressed a pit on Ding's swollen leg. "Women are pregnant so hard?"

    Ding Zhen sternly beside him: "How can this happen again and again. Madam's pregnancy is more difficult."

    Ding desperately wanted to pull down the hem of the skirt, this posture is really indecent. Cao Song smiled and held her down, forcing her not to let go. The two got into a stalemate over the skirt.

    Asheng covered his eyes and ran out, the assist has been in place, the child should withdraw.

    Today, Luo Chi was with Ah Sheng, and he couldn't stop laughing when he left the yard. "Master is more and more interested."

    A Sheng raised his chin: "What's the point of matching my parents? At most, I'm knowledgeable."

    "Yes yes yes. The master has big ambitions. What to do next?"

    "I think my mother is a little hot. Are there any mung beans left? If there is one, let Zhan's make some mung bean soup. As usual, she will watch it herself, and don't let anyone do anything." Sheng wiped the sweat from his head, "It's too hot, I want to get some ice. Even if I don't eat it, it's fine to put it in the room to fan."

    "There is still a lot of ice saved in winter. As long as the owner wants to use it, the big housekeeper will not be stingy."

    Asheng shook his head. Luo Chi was thinking of Cunbing, but she was thinking of saltpeter. Saltpeter can make ice, fertilizer and gunpowder. Nitric acid is one of the three strong acids. Almost like lime and sulfuric acid, it is an industrial raw material that must be obtained.

      Preparation of nitric acid. This method is now tantamount to fantasy. High temperature, high pressure, catalyst, none of the three conditions can be achieved. Then had to go another way: the saltpeter mine.

    The largest saltpeter mine in China is in Xinjiang, and the second largest is in Shaanxi. More specific locations require on-the-spot investigation.

    A Sheng sat under a sweet-scented osmanthus tree and took dead branches to write and draw on the soil. Luo Chi is especially good at eyeing. Once Ah Sheng turns on the contemplative mode, she will automatically quiet down and stand aside.

    Suddenly, the light dims.

    The handwriting on the soil is not easy to identify, and now it is more and more blurred. Ah Sheng stood up and rubbed her head. Her first reaction was heat stroke. But it doesn't seem right, the world dims at a constant rate, like the sun goes down.

    "Ah-"

    "What's wrong with the sky?"

    "The eclipse is over! Don't move! Beware of angering the heavens!"

    Well, the last Ah Sheng understood. eclipse. The surroundings were already in chaos, and there were voices of human trembling and whispering prayers everywhere. To her gratification, Luo Chi was not among them. She stood quietly behind her and grabbed her shoulders, although her hands were shaking badly.

    "Don't be afraid, Ah Chi, it's just an astronomical phenomenon. It will return to its original state in half an hour at most."

    Luo Chi was silent for a moment: "Isn't it a warning from God?"

    A Sheng sneered: "The sun rises and sets, once a day; when the moon is full and the moon is absent, once a month; when spring and autumn come, once a year. The solar eclipse is similar, but it occurs less frequently. , and the intervals are not so regular, the fools panic because of it. If there is an eclipse every day, it will be nothing unusual in a few years."

    Luo Chi didn't laugh, just didn't shake, she said with difficulty: "Master... it's extraordinary."

    A Sheng didn't force her any more, Luo Chi's ability to do this has far exceeded A Sheng's expectations. Ah Sheng took the hand of his personal maid: "While there is still some light, let's go to the mother's yard first. Enter the house and light the lamp, just like the night. It will get darker later, and it will not be good if there is chaos and injury. already."

    "Everyone listens to the master."

    Geely stayed with her grandparents, and it was all right. Then she will work hard and take care of her parents.

    They didn't go very far, they turned a few doors and they could see Ding's yard. The sky became dim, and the courtyard door was like a faded old photo, strange and beautiful. Before Ah Sheng could admire the wonders of nature, he heard Luo Chi shout: "Master, be careful!"

    A Sheng was stunned, looked up at the sky. The sun on the black sky was left with half a crescent shape. I don't know if it was because of the dust or the fog, but she could look directly at the sun, the orange sun.

    No!

    Not dust!

    The sky is filled with small black particles, sweeping over the sky. It's locusts!

    Luo Chi took Ah Sheng into his arms and protected him on the ground. Even so, there were still bugs scurrying in through the gaps in the arms and clothes. Hearing is completely submerged in the "hum" of the insect's wings, and even the struggle of the locusts that have strayed into it can be felt under the arm.

    "Crackling, crackling." Locusts kept hitting Luo Chi.

    "Achi, Achi! Don't be afraid, Achi, locusts don't eat people."

    Luo Chi didn't seem to hear, and still held Ah Sheng tightly.

    "Ah - it hurts - my stomach -" came the woman's cry from the yard.

    "No! It's my mother." Ah Sheng was anxious, "A Chi, A Chi! Mother!"

    Luo Chi stumbled to get up in the rain of insects and ran forward with Ah Sheng in his arms. Ah Sheng struggled to grab Luo Chi's shirt, and the locusts kept hitting the back of Ah Sheng's head, causing her pain.

    But at this time, Ah Sheng didn't care about the pain, nor the cleanliness. Under the double fright of the solar eclipse and the army of locusts, Ding's production situation is not optimistic. Moreover, people are in a mess at this time, and the streets will be even more chaotic. It is a problem to seek a doctor and a stable mother.

    "Everything calm!" Ah Sheng shouted when he entered the door, "It's just dark, the sky and the earth are big, and the baby is the biggest. The mother goes into the delivery room. The lights are all lit, and the hot water is burning. Ding Zhen takes care of her mother. Send someone to Meiyuan to find her grandfather and grandmother."

    Cao Song is a master after all, and he is much calmer than Ding's servants. He was the first to follow Ah Sheng's instructions, picked up Ding and ran into the house. The maids also seem to have the backbone, and they are busy with each other.
