Reborn and married to a stupid scholar, she has a prosperous husband and multiple children

Liu reacted and nodded hurriedly: "I understand, I understand."

"I promise that every penny I earn will be spent on my children. I work day and night to make money just for them."

"Thank you, sister-in-law. Can I...can I call you that?"

Lin Shuangshuang said indifferently: "It's up to you."

Liu carefully took some broken crystals and left excitedly.

Lin Shuangshuang reminded: "You'd better discuss this matter with big brother. Big brother is skilled. Without his help, you may not be able to do it yourself."

"Such a good opportunity to make money depends on whether you can seize it."

Mrs. Liu nodded: "I will go find him right away. I originally wanted to discuss it with him. After all, he is the head of the family. I can't do it without his help."

Dong'er asked in confusion: "Miss, Liu treated you like that before, why did you give this lucrative business to her?"

Lin Shuangshuang said indifferently: "Just think of it as helping the three children of the eldest wife."

"If Liu is truly repentant, I am willing to lend a hand. It's just a small favor."

"Nowadays, the gap between the first and second rooms is getting bigger and bigger."

"The two children of the second wife are already wearing gold and silver, and the three daughters of the third sister are also wearing new clothes and new pants. Only the three children of the first wife are still wearing patched clothes."

"I feel sad when I see this, but I am no longer a housewife, so I can't help too much."

"We can't just give money to the eldest wife. We have to let them find a way to make a living."

"This is a test for Liu. If she can put aside her selfishness, do this well, and live a good life, it will only benefit the first wife."

Dong'er asked curiously, "The crystal is so small and broken, can she find a way to drill a hole in it?"

"My eldest brother is good at carpentry and invention, and he also likes to study. If they discuss it, there should be a way."

"In short, I have given them the idea of ​​making money. Whether they can grasp it depends on their ability."

As for Liu, she went to the main courtyard with an excited look on her face. At this time, only Gu Jinzhong was at home, and the children had all gone to the academy.

When Gu Jinzhong saw that it was her, he couldn't help but frowned, and his tone was also very cold: "What's the matter?"

Liu nodded excitedly: "Something's going on. It's very important, and it's a good thing."

"Let me show you something."

As she spoke, Liu walked up to Gu Jinzhong, carefully took out a handkerchief, and then put it back worriedly.

She looked around, moved a table into the room, took out a plate, and then placed the broken crystals wrapped in the handkerchief on the plate, so as not to worry about them accidentally breaking away.

“Is this crystal?”

Gu Jinzhong recognized it at a glance. He had also seen people from the imperial court mining crystals in the mountains two years ago.

"Yes, it is crystal, but these broken stones are not wanted by the court."

"My sister-in-law said that we can pick up these crystals and make them into hairpins, clothes, jewelry, fortune trees, etc., and sell them for a good price."

Gu Jinzhong was stunned: "You went to look for your sister-in-law?"

"Didn't I tell you not to disturb her?"

Seeing that he was angry, Liu explained with a guilty conscience: "I made tiger-head shoes and tiger-head hats for Tuantuan and Yuanyuan. My sister-in-law took the initiative to tell me about it."

"She also said that the only difficulty now is drilling holes in the gravel, otherwise everything will be in vain, and those things cannot be made without drilling holes."

"So, my sister-in-law said that if we can figure out a way to drill holes, she will let us do the crystal business. She only wants 30% of the profit."

"The rest is ours!"

"I just thought that I must not miss this opportunity to make money, even for the sake of my three children."

"The second wife's children are all wearing gold and silver, but our children are still wearing rags. I feel bad when I see them."

"I know I shouldn't compare myself to others, and I know I'm not as capable as Wang, but I'm also a mother, and I want my children to be well-dressed and well-fed."

"I know I have no right to say this now, but whether you recognize me or not, I am the child's biological mother..."

Gu Jinzhong listened to Liu's words without saying a word, but just looked down at the broken crystal in his hand thoughtfully.

Seeing that he was staring at the crystal, Liu didn't dare to say anything for fear of disturbing him.

She doesn't have the ability to do this, so she can only rely on men.

She knew that Gu Jinzhong liked to study and make some small gadgets, and he had the patience to tinker with them, so maybe he would have a solution.

"Go get the hammer and nails from the toolbox."

"it is good."

Liu was happy to be his errand boy and quickly went into the house to get the toolbox.

Gu Jinzhong first scratched the center of the crystal with a nail to make a mark, then placed the tip of the nail on the dot and gently hit it with a hammer, trying to hammer a hole in it.

Gu Jinzhong worked very carefully and had deft hands, and he managed to smash the crystal without breaking it after several attempts.

Liu sat on the side, holding her breath and watching nervously, hoping that he would succeed.

As a result, the next second, as the hammer fell, the crystal broke into two pieces.

The two stared at the crystal that was broken into two pieces, feeling both distressed and lost.

Sure enough, money is not easy to make, and things are not easy to do.

Even if it is really possible to smash it with a hammer, the efficiency is too slow and the damage rate is too high, so this method is doomed to fail.

"Go get some thicker needle and thread."

"it is good."

Gu Jinzhong thought of drilling wood to make fire. Since fire can be made by drilling through wood, why can't crystal be made by drilling through it?

But he had to find a tool that was right for him. The embroidery needle was too thin and could not be used to drill with just two fingers. It needed a handle.

So he added a round handle the length of a palm to the needle hole overnight so that it could be rotated in the palm of the hand.

When drilling, you have to find a way to keep the crystal still, otherwise it will be impossible to drill.

All Gu Jinzhong needs to do is make a fixer with a spring that can fix any crystal regardless of its size.

After fixing the crystal, I started using the hand drill. After spending a long time, I finally drilled a small hole without cracking the crystal.

But the efficiency is too slow. Gu Jinzhong feels that the drill bit needs to be improved and the drilling speed also needs to be increased.

Embroidery needles are not suitable because they break easily if you drill too fast. You must have a harder drill bit.

And the drill bit needs to have edges so that it can drill faster.

So he asked Liu to find the best blacksmith shop in town to make some hard drill bits.

He continued to study and modify the drilling tools at home, and finally changed the hand-rubbing drilling to hand-crank drilling. This not only saved a lot of labor, but most importantly, it also increased the speed.

After shaking it eight or ten times, you can drill through a crystal.

However, the drill bits made by the blacksmith shop were not hard enough and would be scrapped after just a few drills.

Seeing his frown, Liu said to him in a comforting tone, "I think it's already good enough. At worst, we can just make a few more drill bits."

"Now it's much easier than before. I can just shake it twice and it will go through easily."
