Time passed little by little, and Wang Yiyi was busy all summer. She was not only busy picking herbs, but also wild vegetables. She even took half of her wild vegetables home to cook for the old lady, or made them into dried vegetables, and hid the other half for herself. The space is either made into dried vegetables, pickled vegetables, or directly placed into fresh vegetables, but most of them are fresh vegetables, and some are made of wild vegetables, including dumplings filled with fried wild vegetables and eggs.
Also, this summer, while she had time, she secretly went to a cave and burned a lot of charcoal in her own space. The reason for hoarding charcoal is to save firewood in winter.
But apparently she couldn't afford less firewood, so not only did she burn firewood, she also found a coal mine deep in the mountains.
In ancient times, no one picked the coal, so it was left there looking careless and dark.
Then Wang Yiyi took out the tools she found in the space, pried open a place, and dug out a large area from there. It took her nearly two months to slowly dig out a lot of coal.
She even chopped down all the wooden chairs and other things in the space, put all the cabinets and other things together, and created a layer where the coal was directly stacked.
She used the sixth floor as a storage room to store his fresh goods, such as wild vegetables, and the seventh floor was used to store meat and dried vegetables.
Finally, there was a huge space on the top of the 7th floor, which was an open-air balcony. Someone was having a party there, so she demolished it all.
Pack up all the firewood on the seventh floor and put it together, and then put the coal she had dug for almost a month inside.
The most important thing is that she even developed gunpowder, a simple version, in order to mine coal easily. Although the power is not as good as modern ones, it was still quite useful in ancient times.
After all, she had just finished the college entrance examination, and she still had quite a lot of physics and chemistry knowledge in her head, especially since she was good at chemistry.
Therefore, there is a lot of coal in her space, which is enough for her to burn for four to five years even in the middle of winter. (Four or five years here means burning coal all year round)
After all, she also knew that there would definitely be cold waves and heavy snowfall in the future. She also knows that if there is any disaster, she may be the first to give up. It's not that the old lady must do anything, but that if the old lady doesn't give her anything to eat, wear or drink, then the problem she will face in the future is that as long as the old lady doesn't sell her, someone will try to take advantage of her.
Forgive her for always assuming the worst possible evil in everyone.
With her current attitude, the old lady would definitely not sell her out. But someone will take her idea. Once things get very critical and there is no food, two-legged sheep become the main food, and these are everywhere in history.
Therefore, she not only needs to prevent dangers from her family, but also from dangers from the outside world. For example, if she gets separated, she may be dragged and cooked by others.
The most important thing is that the old man knows that she has silver in her hand, but who can guarantee that the old man will definitely choose this granddaughter in front of his grandson and granddaughter.
So she made complete preparations for herself, and she planned to make gunpowder this winter.
For this matter, she specially demolished a milk tea shop. She did it in the space. She would not take it out unless absolutely necessary.
In order to make chopping firewood less laborious, she would wait until the old lady and the old man went out before going out. She would come back before the old lady and the old man came back and use the space to store a lot of firewood.
So in the second month of autumn, this harvest season, while everyone was still preparing for the wood, she had already prepared the wood. She was very busy picking mushrooms, wild fruits, and wild vegetables every day on the mountain. Of course, half of them had been thrown into space. The most important thing was that she found a bamboo forest. She planned to wait for winter to dig winter bamboo shoots.
As for whether this place will be flooded due to heavy snow, Wang Yiyi is not too worried, because there is a river here, and it is a small river with a slow flow rate, but the amount of water in the river may be less than when she first came here. It has been reduced by half.
And she also discovered that there was a hot spring here with a lot of saltpeter next to it. There was even a lot of realgar, and realgar and saltpeter were rare and good things. It was because of these good things that she was able to make gunpowder.
She used saltpeter to store it for later use.
This thing is hard to come by, easy to get, and can be purchased in pharmacies. She thought it would be better to prepare this thing by herself.
