"Sister Haitang, what is this?" Lamei asked confused.
"This thing will be of great help to us in the future." Bai Haitang wrapped a piece of natural crystallized copper sulfate with the plant leaves she brought. Continuing to walk forward, she found the limestone with her keen sense of smell, shoveled off a piece, wrapped it, and followed it.
Put the hoes together in the basket.
The two came to the back of the mine. It was relatively leeward and no one would notice.
Bai Haitang built a stone nest with stones. Before putting the limestone in, he put some dry pine branches and leaves on it and lit it with flint, thus making a simple stone furnace.
The two kinds of semi-finished products were put in the basket, and the two of them quietly returned to the dealer's place.
"Sister Haitang, every time you couldn't finish weeding, my mother-in-law wouldn't give me food to eat. Today...I don't have anything to eat either..." Lamei said, looking at the weeds all over the crop field.
"It doesn't matter, we have this." Bai Haitang dug a puddle near the crop field, mixed copper sulfate and quicklime in according to the mixing ratio, stirred it with a wooden stick for a while, and gradually turned into a light blue liquid.
"This?" Lamei touched her head and couldn't think of anything that could help others with weeding.
Bai Haitang picked up half of the broken rice bowl, scooped up the solution, and poured it on the crops little by little. After a while, the crops were still green, but the weeds were wilting. In the evening, the weeds were completely staggered...
"Sister Haitang, you, do you know magic?" Lamei was a little scared, she had never seen anything like this before.
"Wangmei, this is not magic, it is science." Bai Haitang said.
"What is science?" Lamei asked curiously.
"Science is..." Bai Haitang found that she couldn't explain the word, "It's just that I had a dream when I was pregnant, and someone in the dream told me to do this."
"Oh, I understand, Sister Haitang, science means having noble people to help you." Lamei suddenly realized. Haitang no longer forced Lamei to understand vocabulary that was not a product of her era.
The two agreed that the nobleman's help should be kept secret, and then continued to make herbicides. At the same time, they improved the weeding equipment and used a bowl to water the weeds, which was time-consuming, labor-intensive, and wasted solution. There was not enough time to make a pressurized watering can.
Bai Haitang took the iron pot over and looked at it several times.
"Lend me your hairpin." Bai Haitang said.
Although Lamei didn't know what to do with the hairpin, the grass was obviously dead. Lamei's trust in Bai Haitang became even more unshakable. She even thought it was magical. The noble person who helped her might be a god.
Bai pricked several holes with the hairpins on her head. There was only a band on her head, so she couldn't do the work of hairpins. In this way, the iron kettle became a simple watering kettle, and she poured the herbicide into it with a broken bowl.
Just keep it wet all the way and wait for the miracle to happen the next day.
The two of them struggled for several hours, and finally the two families' fields were watered. At this time, the mother-in-law, sister-in-law, and brother-in-law were already having sweet dreams on the hot bed.
Gulu, Gulu... Bai Haitang's stomach growled with hunger.
Wintersweet dragged Bai Begonia to the edge of the pond, picked up two duck eggs, and she didn't know whose duck had dropped them. She also dug up two potatoes, buried them in the ground and roasted them with the duck eggs.
Seeing Sister Haitang eating deliciously and contentedly, Lamei felt comforted and sympathetic. A daughter-in-law who came all the way to marry and was bullied by her mother-in-law's family is so pitiful. If she is like this in the future, she will definitely have a good sister.
