The process went more smoothly than expected. When the bottle of blue oil was poured into the diesel engine, it started to generate electricity. Qiao Xuejun used some bamboo poles with light bulbs tied on the top and inserted them into the ground, with a light bulb inserted every five meters, like street lights.
Every light bulb looks different. There are the old tungsten filament incandescent lamps, the current energy-saving LED lamps, as well as art lamps, table lamps... They come in different shapes and are all collected from other people's empty houses.
While Kuang Qianli was connecting the wires and installing the lights, he looked at Qiao Xuejun and sighed, "No wonder you collected so many wires back then. So this is your idea?"
When collecting supplies, Qiao Xuejun went door to door and took away all the electrical wires from people, leaving nothing behind.
Qiao Xuejun did not deny it.
After all, she knew that there would be extreme cold later. In extremely hot weather, you can keep warm underground, but in extremely cold weather, the effect is not so good underground. Although there is a certain warming effect, it is still cold when it is cold, especially when it is flooded underground and the temperature is even lower.
Plants, animals, and humans all need to stay warm. Production requires electricity.
She had not anticipated the current lighting conditions would be so poor, but she was not unprepared because she had collected these wires and household appliances.
Qiao Xuejun made holes along the ridges of the fields to mark them, and soon the finished "street lights" were inserted along the locations where she made the holes.
Every time Kuang Qianli connected a light bulb, Wang Juanfeng would tie the light bulb to the wire and tie it to a bamboo pole, turning it into a "street lamp". After tying it, he handed it to the carpenter, who took the street lamps and inserted them one by one along the holes that Qiao Xuejun had dug in the ground.
"Host, the mall can actually provide a lighting system. Ours is a granary system, and it has everything related to planting."
"Oh, how much food can be exchanged?"
System: "As long as we have 50,000 kilograms of food, we can open the lighting system!"
Qiao Xuejun: "Fifty thousand? The whole land?"
For her, it is actually still within an acceptable range. After all, it would cost a lot for her to do it herself.
She originally thought that this function would be very expensive. After all, a well requires 100,000 kilograms of grain to open.
The system slowly added: "Fifty thousand for lighting one acre of land."
So she now has 15 mu of land, which would cost her 750,000 kilograms of grain.
The light in Qiao Xuejun's eyes went out: "Please tell me earlier next time. Thank you."
After a while, Qiao Xuejun asked again: "I added a lighting system to the shelter. Is there a reward? 750,000 kilograms of food?"
When she added chicken coops, rabbit coops and wells to the shelter, she was rewarded. The chicken coop required 10,000 kilograms of food to be exchanged in the shelter, so the system rewarded her 10,000 kilograms.
Now wouldn't these lighting systems also be worth $750,000?
System: "Yes, host, wait a minute, I will apply for an evaluation!"
After a while, the system reported: "Evaluation completed, host, congratulations, the lighting system is worth 100,000 kilograms of grain!"
Qiao Xuejun was dissatisfied: "Why is there only 100,000? Where is the remaining 650,000? Are you making a profit as a middleman?"
System: "Host, yours is too crude. Our mall provides professional plant lights, which are very expensive! Yours is pieced together from various sources, and it's ugly! The effect is not good either!"
At this point, Qiao Xuejun reluctantly admitted: "Okay, 100,000 is fine."
Because the system was right, the street lights she made were mediocre, and the fill light effect was also mediocre. Plants mainly absorb red and blue spectra, and the ones she collected were mostly household energy-saving lamps, which were not as efficient as special plant lamps.
There is also an incandescent lamp, which only has red and yellow light, no blue spectrum, and is even less efficient.
But after all, it is the end of the world, and with these conditions, most of them are LED energy-saving lamps, which also have red and blue light. So they can still be used, but relatively speaking, the time to turn on the lights every day is longer.
Moreover, getting 100,000 tons of food for free, how can it not be a happy thing?
Some blue oil can be exchanged back, but unfortunately the speed of blue oil production in the First Base cannot keep up, otherwise it could be exchanged immediately.
A lamp was installed every five meters, and finally there were several hundred lamps installed in total, almost all of the lamps that were collected were used.
The entire planting area is as bright as day.
Not only lights, now that we have energy, the distiller can also boil water all day long, and that water can be used to irrigate the fields.
Now I feel relieved, I can continue to grow crops in the planting area. Now I don't need to plant all potatoes, I can use two acres of land to plant some fruits and vegetables.
Kuang Qianli said: "It's blinding. Fortunately, our bedroom is separated from here by a large living room, so the light can't get in. Otherwise, how would we sleep at night?"
Now they have a generator, but it is installed in the middle of the growing area, several acres away from their bedroom.
There are several doors in the middle, so it is not as noisy as when it was placed in the warehouse.
Kuang Qianli also made a soundproof box for the diesel engine to further reduce the noise and not affect sleep at night.

Qiao Xuejun went to the warehouse to count the seeds she had bought. She bought high-yield and easy-to-grow varieties of fruits and vegetables, such as apple seedlings and chestnuts. The chestnuts didn't even need watering.
But she also bought some blueberry seeds.
Blueberries are rich in anthocyanins, and maybe they can be processed into reagents for pH testing.
As for the more delicate fruits, Qiao Xuejun didn't buy any, after all, she didn't have enough money at the time. If she had more money, she would have wanted to stock up.
