My Black Tech Shelter

At nine o'clock in the morning on May 26, Lu Chen slept until he woke up naturally. He no longer had to wake up from the cold like he did a few nights ago without covering the quilt properly.

After measuring the temperature, the temperature inside the shelter has reached 20 degrees, which is a more suitable temperature for the human body. It neither feels hot nor cold.

Lu Chen got up and took a look. After one night, the nano core had gathered another 200 points of energy. Now he was considering whether to upgrade the defense or the plant cultivation room first.

After thinking for a while, Lu Chen decided to upgrade the plant cultivation room first to a small planting base of 500 square meters, of which 100 square meters will be used to grow vegetables and 400 square meters will be used to grow hybrid rice.

However, the current area of ​​my cultivation room is only 100 square meters, and I still need to expand the space to 400 square meters, which is estimated to consume a lot of energy and materials.

Then Lu Chen did some design calculations in the nano core and found that 5 tons of sand and gravel materials, one ton of cement, and 2 tons of steel were needed.

Lu Chen calculated his inventory and found that it was not enough. Now he felt a little uncomfortable. Finally, he found that he only had enough materials to widen the area by 100 square meters.

After thinking for a while, Lu Chen decided to expand the space by 100 square meters first, and then use the 200 square meters of space to grow vegetables. Last time he went to exchange for water purifiers, he saw the official shelter purchasing various supplies, including vegetables and fruits. The value is still relatively high.

At present, my rations are still sufficient, so I can use the two hundred square meters of space to plant a batch of vegetables. Chinese cabbage and lettuce can be matured and harvested in one month. This way, I can trade once a month without going out frequently. , and you can also get a lot of supplies, which is generally good.

Lu Chen started to create a nano-hive. He spent a hundred energy points and some materials to expand the growing room to 200 square meters, and then began to design a transformation plan for the growing room.

"First, use ordinary soil for cultivation. If you use soilless cultivation, you can save a lot of space. However, I don't have a formula for the nutrient solution now. I have included it as an alternative. The soil can be planted outside before frozen soil has formed, so hurry up. After excavation and the extra soil from the expansion, it is probably only necessary to replenish one-third of the soil.

Secondly, growing vegetables requires a lot of water, and if planted for a long time, the fertility will decrease, so you have to look for fertilizer outside. There happens to be a fertilizer factory in a nearby town. You can check it out later.

For water, you can spray it from the sky, so you can open the valve from time to time to water. Finally, there is the issue of lighting. Plants need photosynthesis, so the one sun lamp prepared before is not enough, and several more have to be made. ,

Finally, we can calculate the yield and estimate how many kilograms of lettuce can be harvested from planting 200 square meters of cabbage or lettuce. Currently, I only have a pickup truck with a load capacity of about 1.5 tons, and I plan to plant half of it with cabbage and half with lettuce. In this case The output of cabbage is about 400kg and lettuce is about 100kg.”

"If a batch matures every month, then I can exchange building materials every month. In this way, my growing room can be expanded once a month. The plan is to expand it to 500 square meters.

However, if there are more materials in the later stage, just add 200 square meters. In this way, 400 square meters can be used to grow staple crops, and there will be a big surplus for two crops a year. 300 square meters can be used to grow vegetables, so that you can ensure your own consumption while still being able to trade.

I can plant grapes in the remaining 100 square meters. There is no big requirement on the height, so that I can eat fruits. As for meat, I also bought a lot of canned pork and beef. I will eat it with it for the time being. I will see if it can be mixed with it later. Officially redeemed. "

After Lu Chen completed the planning, he used the nano core to spend 100 points of energy to create a nano insect nest according to the settings in his mind.

Then he took the insect nest and entered the planting room to start it. Then Lu Chen left here and started digging soil outside the shelter. After spending a few hours, Lu Chen dug enough soil and sent it back to the shelter. Only then did Lu Chen have time to look. A look at the changes to the grow room.

I saw that the construction of the planting room has been completed, and the indoor height is about three meters. There are more than ten solar lamps distributed at the top for photosynthesis. There are several rows of pipes below the solar lamps, and there are nozzles at regular intervals. Make sure there are no blind spots when spraying water.

On the ground, the field ridges made of steel divided four open spaces, and each open space has been paved with soil.

Lu Chen took out his shovel and dug up a spot, and found that the soil layer was not very deep. Then Lu Chen poured the collected soil evenly into the four open spaces until it was almost as high as the field ridges.

Lu Chen estimated that the thickness of the soil layer was almost one meter. In this way, there would be no problem in growing vegetables, rice and wheat. Then Lu Chen took a shovel and tidied up each piece of land, and then left the planting room and opened the valve. , make the land moist.

Afterwards, he checked the time and saw that it was already past three in the afternoon. Lu Chen put on his equipment and left the shelter, planning to drive to the fertilizer factory to see if any fish had slipped through the net and get some fertilizer back.

Half an hour later, Lu Chen arrived at the door of the fertilizer factory. As soon as he got off the car, the smell of urea came over him. After making sure that he was looking for the right place, he opened the door and found that it was empty.

It took Lu Chen ten minutes to go in and find the warehouse where the fertilizers were stored. Fortunately, there were still a few bags of urea and compound fertilizers in the corner that had not been transported away.

Lu Chen left the factory door, drove in, put the fertilizer into the car, and then went to other places to see if there was any harvest.

Lu Chen came to a production workshop and opened the door. It was dark inside. Lu Chen turned on the flashlight and walked in. After looking around, he found that there was still a lot of fertilizer at the outlet of the production line.

But they were all in the discharge barrel without packaging. Lu Chen looked around and found some plastic bags scattered around. Lu Chen took the plastic bags and put them in the discharge port and started to manually fill them. However, this discharge There wasn't a lot of fertilizer in the bucket. I only put two bags in it and it was gone.

Lu Chen looked at the plastic bag. It said "Chengtian Fertilizer Factory" and the words "25kg" below it. Two bags were almost 100 kilograms. The warehouse used to have such small packaging.

Lu Chen estimated that it was missed because of the small packaging. After all, the big ones were more conspicuous and difficult to miss.

Then Lu Chen found two more production workshops. The harvest from these two workshops was quite rich. A total of 200kg of fertilizer was collected and transported all to the car. Lu Chen stood by the car and looked at it, and there was probably no harvest. , got in the car and left.

Lu Chen was driving on the road when he suddenly saw a private gas station on the roadside. It was a very small one with only a front room. However, Lu Chen found that the front room was open and there was no one inside. It was probably for the whole family. It was an official shelter. Lu Chen pulled over and parked the car, ready to go in and take a look.

Lu Chen entered the front room and looked around. He found that the oil tank inside must have been removed. Then he found that there was a door inside, which should lead to the backyard. Lu Chen opened the door and went in, and found that there were two more doors in the backyard. There were two large oil tanks, one with diesel and the other with gasoline. Lu Chen walked to the side and checked, and was disappointed to find that there was no oil in it. Then Lu Chen checked again in the backyard. After searching for a long time, he finally found it again. An oil drum was found in the utility room. It was covered with dust and contained about a hundred liters of diesel oil.

Lu Chen was pleasantly surprised, but looking at this oil drum was a bit confusing. One liter of diesel weighs about 0.86kg, and one hundred liters is 86kg, which translates to 170 kilograms. It is so heavy.

Lu Chen couldn't move it for the time being. After all, the exoskeleton booster he planned to build had not yet been manufactured, and the crane he planned to build on top of the pickup truck had not yet been built because of energy issues, so it was so heavy. Lu Chen really couldn't do anything about the oil barrel.

Lu Chen thought for a while and decided to find something to pull out the oil first. He took some out and put it in the car. It happened that the car didn't have much oil left. Then Lu Chen found a smaller plastic oil drum marked 20 liters.

Using the siphon principle, he pumped a full bucket of oil, then walked to the car and started filling it with oil. After filling it, Lu Chen found a few 20-liter plastic oil drums and pumped out all the diesel in the iron oil drums. After getting out, he put the diesel in the car and found a few empty diesel barrels to put in the car. Lu Chen drove back with satisfaction.

Ten minutes later, Lu Chen returned to the shelter. After putting all the harvest in the warehouse, Lu Chen took the cabbage seeds and fertilizer to the planting room and planted the seeds.

After applying fertilizer, Lu Chen took a bucket and watered every place. Then he went outside the door of the planting room to set the on and off time of the sun lamp, and then set the changes inside the planting room and the shelter. number of breaths,

This will ensure that photosynthesis can proceed normally, and with regular water spraying to ensure moisture, Lu Chen estimates that it will grow well.

After finishing all these things, it was almost eight o'clock in the evening. Lu Chen finished his meal happily and checked the situation online. He found that there were news everywhere in the country that officials were sending troops to collect supplies and build bases.

Then Lu Chen used the computer skills he learned to go abroad and saw chaos abroad. There were shootings and robberies everywhere. Many shelters were attacked and plundered by bandits. Official shelters abroad were also unable to suppress them due to lack of manpower.

The worst among them is the Kingdom of the Sun and the Kingdom of Stars and Stripes, because one of the two largest meteorite fragments fell on the Holy Mountain of the Kingdom of the Sun, and the other fell in the Volcano Park of the Kingdom of Stars and Stripes. It was these two volcanoes that were erupted by the impact. , leading to global volcanic eruptions, so a large number of shelters in the two countries were destroyed, and more than 50% of people and materials were lost.

And because it is right on the edge of the volcano, volcanic ash is everywhere. Surface crops are covered in volcanic ash and die. Some personal shelters with insufficient ventilation facilities are no longer viable. Everyone must wear protective masks when leaving the shelter to avoid inhaling volcanic ash. Officials are already organizing the production of a large number of protective masks, but production lines and resources are insufficient and production capacity is limited.

Lu Chen also saw the Sun Kingdom calling on the Dragon Kingdom for support online, hoping that the Dragon Kingdom would uphold humanitarianism and provide assistance to the Sun Kingdom.

However, Dragon Kingdom responded that domestic supplies were insufficient and could not provide support. However, as a member of Blue Star, considering the limited production capacity, Sun Country could use materials in exchange. However, because this is a special period, the price may be relatively high. I hope Sun Country can consider it. Whether to trade.

Lu Chen smiled knowingly when he saw this and browsed for a while. Among them was a message about a laboratory in a foreign country that was damaged due to an earthquake. However, Lu Chen just looked at it and flipped through it.

After a while, Lu Chen was about to log off and rest when he suddenly saw a post from an environmental scholar. It said that the oxygen content of the atmosphere would decrease. It was said that volcanic eruptions caused by meteorite impacts would fill the atmosphere with volcanic ash, blocking sunlight and causing surface vegetation. and massive die-off of marine algae,

This will lead to a decrease in photosynthesis, an increase in carbon dioxide, and a decrease in oxygen content. It is also stated that as long as the oxygen content decreases by about 2%, most people will experience plateau reaction and feel suffocated. In the future, the oxygen content will further decrease as time goes by. It is hoped that the government and others will be prepared.

Lu Chen also felt that he had to prepare early. No wonder physical labor has been so tiring recently. It turned out that the oxygen content was decreasing. Then Lu Chen thought that it was not only about indoor oxygen production, but also about carrying oxygen when going out.

Then he thought of the protective clothing in a science fiction film "The Wandering Planet". It was a good idea, and he could also realize it himself, such as high-energy batteries, mechanical exoskeletons, high-strength protective fibers and other technologies.

And even if the equipment in the shelter cannot be manufactured, it can be manufactured using nano cores. At most, it will cost more energy, and it is not disposable.

Then Lu Chen looked at the time and it was almost ten o'clock in the evening, so he went offline to wash and go to bed.

"I will think about the method of indoor oxygen production tomorrow. I am too tired today."

Lu Chen lay on the bed and fell asleep slowly. Tomorrow is a new beginning.

This is the only one for today. I have some things to do during the day and don't have time. But I can make another one tonight during the night shift. I'll probably post it before 8 o'clock tomorrow morning.
