Fall in love with the technology tree [Three Kingdoms]

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

Whenever there is a leap month, Ah Sheng, who is used to the solar calendar, feels uncomfortable with the current calendar.The weather is already unbearably hot, the sun is shining brightly, and the cicadas are constantly singing. 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, many chickens in the chicken farms in the suburbs of Beijing should die of illness.It was the first time to try intensive farming in ancient times, and there was no chicken plague vaccine, so Ah Sheng was already mentally prepared.But I don't know if it's because the breed of chickens today is different from that of later generations, or because the Newcastle disease virus has not yet been introduced into the country, and the death rate is not as high as Ah Sheng expected.Even if it is a dead chicken, the death symptoms are not the typical death symptoms of chicken plague.

Ah Sheng had no choice but to make gloves, a mask and a simple version of protective clothing, and asked Liu to change and wash them every day.Susceptible chicken breeds need to be eliminated, but at the same time, enough genetic diversity must be retained in the flock to resist future unknown viruses.Ah Sheng calculated the genetic map until he got a headache, and he didn't know how much the papyrus was useless.

Today's Cai Lun paper is yellow and brittle, and wood fibers of different thicknesses can be seen in the paper, which the wealthy people look down upon.If you want whiter and softer paper, the cost will increase significantly. The bleaching process depends on the ultraviolet rays in the sun, and the time spent is calculated on the basis of years.However, Feitinghou's mansion bought a lot of crude yellow paper with raw edges, except for the masters to use the toilet, the rest were all used for Ah Sheng to make drafts.

In the last few days of Leap May, no new sick chickens were found, which made Ah Sheng heave a sigh of relief.The first batch of mung beans has not yet produced fruit.By next year, she will be able to feed chickens with mung beans and ginger mixed with a low-concentration potassium permanganate solution. This indigenous method is said to prevent chicken plague.In the absence of a vaccine, the local method is already the best way.However, she has to get potassium permanganate... emmmm, it's a pity that there is not even a Taoist temple in this era, so she has to find an alchemist.

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

And Ah Sheng didn't have a clear plan.She was born in the upper class, and she has everything needed for food, clothing, shelter, and transportation. Even if she doesn't do anything, she can live in luxury for a lifetime.If she had been born into an ordinary family, she might have been eager to pick out easy money items, soap...whatever.But she is a local tyrant, and the main conflict in her life is house fighting and political fighting, which is hard to describe.

Ah Sheng set the first core project as raising chickens because of his maid Yan Wen.Her family was ruined by the locust plague.

According to Zhao Gou, locust plagues occur every few years.At this time, the court's way to deal with the locust plague is to raise the moral level of officials!It is said that a locust plague broke out in Henan several decades ago, and more than 20 counties had no crops. However, M County, which was surrounded by the disaster area in the center, did not have a single locust.The results of the investigation showed that because the county magistrate of M county had outstanding moral character and clear politics, God was moved to keep M county away from natural disasters.Zhao Gou said that he was very yearning, and finally concluded: "It must be because there are treacherous people in the court that natural disasters will continue in the capital."

Ah Sheng... Ah Sheng couldn't complain.

Raise chickens to raise an army of millions, and fight wherever you can in the future.In fact, the ability to raise ducks to control locusts is not weak, but because the farm that Cao Teng allocated to A Sheng is not adjacent to the water, it is more suitable to raise chickens overall.Just to supervise the chicken flock and prevent insects and theft, a few big white geese were mixed in the chicken flock.Occasionally, Ah Sheng would feel guilty that these geese couldn't swim in the water, which was purely hypocritical.

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

"The mother is giving birth to the father, so of course the father has to take care of her!" Ah Sheng spoke plausibly, making the parents blush.

Feeling curious, Cao Song pressed a hole on Ding's swollen leg. "Is it so hard for women to get pregnant?"

Ding Zhen stood beside her with a straight face: "How can it be like this every time. Madam's pregnancy is more difficult."

Ding desperately wanted to pull down the hem of the skirt, this posture was really indecent.Cao Song smiled and held her down, forcibly refusing to let her go.The two stalemate over the skirt issue.

Ah Sheng covered his eyes and ran out, the assist was already in place, so the kid should withdraw.

Luo Chi was following Ah Sheng today, and he couldn't stop laughing when he left the yard. "The master is getting more and more excited."

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

"Yes, yes. The master has great ambitions. What are you going to do next?"

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

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

Asheng shook his head.Luo Chi thought of storing ice, but she thought of saltpeter.Saltpeter can be used to 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.

In later generations, the main source of nitric acid compounds is ammonia synthesis technology, which directly combines nitrogen in the atmosphere and hydrogen generated by electrolysis of water under high temperature and pressure to generate ammonia that can be used by humans, and then oxidizes ammonia to produce nitric acid.This method is tantamount to fantasy now.High temperature, high pressure, catalyst, none of the three conditions can be met.Then we have to go another way: saltpeter mines.

The largest saltpeter mine in China is in Xinjiang, and the second largest is in Shaanxi.A more specific location requires on-site inspection.

Ah Sheng was sitting under an osmanthus tree, writing and drawing on the soil with dead branches.Luo Chi was especially good at watching. Once Ah Sheng turned on the contemplative mode, she would automatically quiet down and stand aside.

Suddenly, the light dimmed.

The handwriting on the soil was not easy to read, but now it is getting more and more blurred.Ah Sheng stood up and rubbed his head. Her first reaction was heatstroke.But it didn't seem right, the world dimmed at a constant rate, like the sun setting.

"what--"

"What's wrong with the weather?"

"It's a solar eclipse! Don't move! Be careful not to offend the sky!"

Well, the last Ah Sheng understood.eclipse.The surroundings are already in chaos, and the voices of human beings trembling and praying in low voices are everywhere.To her relief, 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, 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 heaven?"

A Sheng laughed: "The sun rises and sets once a day; the moon is full and the moon wanes, once a month; spring and autumn come and go, once a year. Solar eclipses are similar, but they occur less often and the intervals are not so regular. Fools." That's why I panic. If there is a solar eclipse every day, it will be nothing unusual after a few years."

Luo Chi didn't smile, but stopped shaking. She said with difficulty, "Master...is really extraordinary."

Ah Sheng didn't force her anymore, Luo Chi's ability to do this has far exceeded Ah Sheng's expectations.Ah Sheng took the hand of his personal maid: "Let's go to mother's yard while there is still some light. Enter the house and hold the lamp, and live as if at night. It will be darker later, and it won't be good if there is a mess and get hurt." gone."

"Listen to the master."

Ji Li stayed with his grandparents, so he thought it would be fine.Then she will work hard and take care of her parents.

They didn't go far just now, and after turning a few doors, they could see Ding's yard.The sky became dim, and the courtyard gate looked like a faded old photo, weird and beautiful.Ah Sheng hadn't admired the wonders of nature when he heard Luo Chi yell, "Master, be careful!"

A Sheng was taken aback, and looked up at the sky.The sun in the black sky was only half of the crescent shape. I don't know if it was because of the dust or the mist, but she was able to look directly at the sun, an orange sun.

wrong!

Not dust!

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

Luo Chi hugged Ah Sheng into his arms and hugged him to the ground.Even so, bugs still came in through the gaps in the arms and clothes.The sense of hearing is completely submerged in the "buzzing" sound of insect wings flapping, and even the struggle of locusts that strayed into it can be felt under the arms.

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

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

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

"Ah—it hurts—my stomach—" a woman shouted from the yard.

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

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

But at this time, Ah Sheng couldn't care about the pain, nor his obsession with cleanliness.Frightened by the solar eclipse and the army of locusts, Ding's production situation is not optimistic.And at this time, people are in a mess, and the streets will be even more chaotic. It will be a problem to ask a doctor or a stable woman.

"Calm down!" Ah Sheng yelled as soon as he entered the door, "It's just dark, the sky is big, and giving birth is the biggest thing. Mother goes into the delivery room. The lamps are lit, and the hot water is boiled. Ding Zhen takes care of the mother. Then send I will go to the plum garden to find my grandparents."

After all, Cao Song is a master, and he is much calmer than Ding's servants.The first one to react and obey A Sheng's order, picked up Ding Shi and ran into the house.The maidservants also seem to have a backbone, and they are busy with their own work.
