On the tenth year after the natural disaster, I went to farm with me

After the great evolution of Blue Star microorganisms, the difficulty of preserving food has increased significantly. Humans have thought of many ways to extend the shelf life of food.

Xia Qing's method of first drying and then draining the air from the vacuum bag is a commonly used low-cost food storage method.

This method only isolates the impact of "aerobic bacteria" and abnormally active bacteria in the elements on food, but it cannot inhibit the toxins produced by "anaerobic bacteria".

Even for storable grains such as unhulled wheat and corn, the maximum shelf life using this method is only three months.

After three months, even if the food still looks good, the toxins produced by evolved anaerobic bacteria have caused the food to spoil.

Evolved anaerobic bacteria produce a variety of toxins, including Evolved Botulinum, one of the most toxic biotoxins after the great evolution of Blue Star organisms.

Evolved botulinum toxin cannot be killed after being boiled in boiling water for several hours, so no one will risk their lives to fight the evolved bacteria unless they are about to starve to death.

In addition to this simple method of storing food, there are several cost-effective and effective methods. The more commonly used one is the food storage bin.

Storage warehouses are built in the planting and breeding centers in the safety zone to store food. Storage warehouses can extend the shelf life of food. Main food crops can be extended to more than one year. Onions, potatoes, sweet potatoes, eggplants, cabbage and other vegetables that are easy to store can also have a shelf life of more than three months in storage warehouses.

After the great evolution of microorganisms, it is already remarkable that such a storage period can be achieved.

Xia Qing is not a skilled worker and is not qualified to participate in the construction of storage warehouses, so she has not yet understood the operating principles of food storage warehouses. She only knows that storage warehouses need to meet two basic conditions: one is to filter out poisonous elements in the air; It is temperature and humidity control.

The destructive power of Blue Star microorganisms is directly proportional to the content of the element chlorine in the atmosphere. After the element chlorine reaches a certain concentration, the destructive power of the microorganisms even increases exponentially.

Temperature and humidity control are easy to say, but it is very difficult to filter pollutants in the air, so the cost of building a food storage warehouse is very high, and the cost of maintaining the storage warehouse is also prohibitively high.

Before getting the Yi stone, Xia Qing never thought about long-term storage of food in his territory. One is because she doesn't know how to build a storage warehouse and doesn't want to find anyone to do it. The other is the cost. It's not worth it to build a storage warehouse for the three melons and two dates she has grown or collected.

There is another very important point: Xia Qing overheard Tang Zhengrong introducing to Huang Jie, the Territory Management Minister of Huicheng General Base, at the agricultural products fair that the planting area of ​​Huisan's entire territory was 1,358.6 acres.

How did you get this number with both zeros and integers?

Xia Qing has been in the territory for half a year, but the territory management department has not sent anyone to inspect or measure the planting area in Territory No. 3. Xia Qing has not heard that they have measured the planting area in other territories.

Without on-site surveys, there is only one possibility left to obtain such detailed data: the data was obtained through satellite measurements by the Territory Management Department.

The cosmic gamma ray burst in the early years of the natural disaster destroyed all Blue Star's mid- and low-orbit satellites, leaving only a few high-orbit satellites launched by China. After the natural disaster, all countries were working hard to restore communications. Xia Qing heard several times through the radio that China had successfully launched satellites.

Since the base can use satellites to measure the planting area of ​​the territory, it can monitor every move in the territory. This is why Xia Qing is the only one in the territory, so she is cautious and secretive when going to get spring water.

Although she is now just one of the inconspicuous lords in the two hundred territories of Huisan Base, the sudden addition of multiple solar panels and the construction of food storage warehouses in her territory will definitely attract the attention of the lord management department.

Xia Qing just wants to live a low-key and high-quality life and doesn't want anyone to pay attention to her, so she is unwilling to make big moves.

Now, she has Yishi, which solves the biggest problem of food storage. As long as you dig a cool, dry cave and protect it from moisture, insects and bacteria, you can store food.

The shelf life of food stored in this way is longer than that of food stored in vacuum packaging!

There are so many mountains in her territory, wouldn't it be simple to dig a cave?

Xia Qing happily ate the Dimin fruit, laid out the detailed map of Territory No. 3 and the three areas of Mountain No. 49, and began to select a site.

She exchanged vegetables for these two drawings with Zhong Tao. She drew the map of No. 3 Territory herself, and she asked Luo Pei to draw the map of District 3 of No. 49 Mountain. The crops she grows, as well as the native edible plants found on the property and in the three zones, are penciled in at corresponding locations on the map.

It can be said that these two are her own treasure maps.

Xia Qing first added the positions of the three pieces of ground fruit, and then looked at more and more small dots, small circles or small squares on the drawing, feeling full of accomplishment.

Because these are food, nothing makes people feel more secure during natural disasters than food and weapons.

The more than 15,000 acres of forest and cultivated land in the picture belong to her. She can dig the cave wherever she wants, as long as the depth of the cave does not exceed thirty meters.

Because if it exceeds 30 meters, it will destroy the internal structure of the mountain and may affect the most precious survival resource it has: pollution-free spring water.

Xia Qing hesitated for a while between the third area and the buffer forest, and decided to dig the cave in the west buffer forest.

Although the third area of ​​Mountain No. 49 belongs to her, the altitude is higher than that of the buffer forest, making it easier to control the temperature. But Xia Qing was worried about putting the food in a place where it could not be seen or heard at any time.

After the site selection was completed, digging the cave was a piece of cake for Xia Qing, who had the tools and strength.

There was no rush, and she began to deal with the most critical "technical means" for preserving food-making a stone protective shell.

After opening the information sent by Luo Pei and studying it carefully, Xia Qing, who had three months of experience in blacksmithing, felt that it was not too difficult.

To make a Yishi protective shell, you need to first melt the gravel screened from the Yishi surface and the soil near the Yishi at high temperature, then add a certain proportion of iron, carbon, silicon, manganese, nickel and aluminum to melt and cast it into a shell with a certain thickness. That’s it.

Xia Qing took out her tool bag and looked through the supplies she had accumulated over the years. She has iron, carbon, silicon, and aluminum, but manganese and nickel need to be purchased.

Xia Qing took out her mobile phone and sent a message to Zhong Tao.

Zhong Tao quickly replied: No problem, why does the girl want these?

Xia Qing replied: My machete is broken. It is too expensive to take it back to the safe area to repair it. I plan to make a new one. I worked in a blacksmith shop in the safe area and know a little bit about blacksmithing techniques.

Zhong Tao, who had just walked into the military canteen in the safe zone, was stunned for a few seconds before typing a reply: Girl, is there anything else you can't do?

Xia Qing chuckled and put the phone back in his pocket.

"What are you doing if you don't go get food and prepare an itinerary for your wife?" A brother from the same camp came over with a dinner plate and asked casually when he saw Zhong Tao standing in a daze.

Zhong Tao ran to get food and came back and asked his comrades around him, "Do you think a woman who can farm, build a house, and make iron needs a man?"

Zheng Kui knew who Zhong Tao was talking about as soon as he heard it and didn't say anything. The brother next to him said, "It's not whether she needs a man, but does any man dare to marry such a woman? Do you dare?"

Zhong Tao's head was shaking like a rattle. He didn't dare to think anymore and just kept busy with his food.

In Territory No. 3, Xia Qing first gave clean drinking spring water to the two distinguished guests at home, then listened to the radio and picked up the chickens that had been put into the cage, put them into the tool room, and then started to cook dinner for himself and the sheep boss.

After eating something greasy at noon, Xia Qing decided to eat something light in the evening. Mung bean rice porridge, white flour pancakes, cold vegetables, chopped bird's blood and a few pieces of grilled egret meat, all together.

The sheep boss eats compressed rations mixed with young toon leaves and pasture. The alfalfa and perilla flowers smell amazing after they bloom. Now, let alone eating, they are just passing by. Xia Qing and the sheep boss want to take a detour.

After finishing the meal, Xia Qing stood in the room and shouted loudly, "Boss, it's time to eat."

The sheep boss, who was lying in the sheep shed and chewing cud, completed the whole sequence of washing his feet, rubbing the grass, opening the door and entering the house and serving the table in a few seconds. He squinted at Xia Qing.

Where's the meal?

Xia Qing took out its rice bowl and pretended to be disappointed, "Boss, after your friend came, you stopped sticking to me. I'm very disappointed."

Lost, what is that thing, is it delicious? The sheep boss only followed the rice bowl with his eyes.

Xia Qing, who was playing the piano to the sheep, was speechless. He put down the rice bowl and rubbed its horns hard, "You heartless!"

Xia Qing couldn't let the light out at night. Xia Qing closed the security door tightly, pulled down the blackout curtains, and then turned on the headlights. After going to the kitchen to wash her hands, she brought her food to the dining table and shouted happily, "Let's eat!"

The amber eyes of the brain-evolved wolf lying in the sheep shed stared in the direction of the closed security door for a while before slowly closing it.
