When they came back from the front yard, the couple had already sat down and were talking to Wang Jinhua with smiles on their faces.
Seeing Meng Qidi coming in, Wang Cuihua hurriedly said, "Xiao Qi, we've thought it over, let's do it! Even cash is fine."
Ling Tiansheng nodded, "Xiao Qi, uncle was confused before. I promise that I will never be confused again in the future."
If there hadn't been a glimmer of greed in Ling Tiansheng's eyes, Meng Qidi might have believed him a little.
However, she couldn't control whether they were stupid or not, as long as it didn't affect their family. Otherwise, she would make him regret it for the rest of his life.
Since the couple wanted to build a septic tank, Meng Qidi naturally had to go over and take a look.
Ling Jinming followed with a pencil and paper. He had to draw a picture, calculate the volume, and figure out how much cement and labor would be needed, including steel bars.
Meng Qidi was traveling with them. Along the way, the couple stood up straight and told everyone they met with dignity that they trusted their niece-in-law and that it would always be right to follow her.
Meng Qidi naturally did not stop them from indirectly advertising for her. She also knew why the couple changed their attitudes over the past few days.
I guess he found that his family was getting better and better, and he couldn't take advantage of it, so he just followed suit...
Thinking of the two piglets in the backyard, Meng Qidi's mouth twitched. She was afraid that the couple behind would follow suit?
What about her future registration of a biogas digester company? What about her greenhouse vegetables?
Well, she was disgusted at that moment, but she was not afraid of imitation. Wasn’t there an advertisement in later generations that said, no matter how you imitate, you can’t imitate my taste?
As long as she reforms and innovates fast enough, no one will be able to catch up with her.
She didn't intend to become a professional pig farmer by raising piglets, she just wanted to make some pocket money for the family.
As for starting a company, that was not her idea, but Ling Jinming's. When she made money and was ready to come back to start her own business after graduation, she would quit and give the entire company to Jinming.
She is not a good person at all. These careers are just stepping stones for her. She has only one goal, which is to make a fortune with Yuquan water. It is hard to say what the road ahead will be like.
But she was sure that she would not be limited to being a pig farmer or a septic tank beauty.
Speaking of which, it was Meng Qidi's first time to visit Uncle Ling Xiao's house. The house was clean inside and out, and the chickens and ducks were kept in the backyard.
It is much wider than the previous Ling family's. Although there is no yard, there are many rooms once you enter the gate. I'm afraid there are also some former rooms of the three families inside.
Meng Qidi glanced at him and then looked away.
I followed Ling Tiansheng and his wife to the backyard. There was a wide open space at the back, and further back was a row of utility rooms, which were probably used as pig and chicken pens.
Seeing Meng Qidi looking around, Wang Cuihua asked hurriedly.
"Xiao Qi, how about it? How wide can it be? Don't make it as small as yours. It should be big enough to cook two dishes, right?"
Meng Qidi retracted her gaze and instructed Ling Jinming, "Come with me, I will measure your feet, and you use a ruler. Remember to write down everything I say next."
Ling Jinming nodded quickly and followed nervously.
Meng Qidi was actually teaching on the spot. Ling Tiansheng and his wife looked at each other, a hint of joy flashed in their eyes, and they quickly followed, pricking up their ears.
Meng Qidi ignored them and walked into the backyard. She tapped the ground lightly a few times before speaking.
“Do you know what biogas is?”
Ling Jinming nodded quickly, "I went back and read a lot of books these past two days. Methane can ferment under certain temperature, humidity and pH conditions."
Meng Qidi nodded, bent down, picked up a stick and made a mark, "Yes, there are several types of biogas production. What we are going to do now is to make it artificially. There are also many types of biogas pools. You can choose according to the temperature and geology."
Ling Jinming listened carefully and took notes quickly.
Many of Meng Qidi's words were filled with professional terms, and the couple behind her looked confused.
"The soil of my uncle's house is a bit soft and close to the water, so it's quite damp. We have to stay away from the water source, otherwise there will be too much water when digging. We can use a fixed hydraulic biogas digester directly. This saves labor and materials. The soil is soft and in close contact with the surrounding areas of the biogas digester, which can keep it warm."
Meng Qidi made another mark in the corner. "Usually, it is more convenient to make this kind of fixed hydraulic biogas digester. By the way, how many livestock do you plan to raise in the future? How many people are there in your family?"
Being asked this question suddenly, Ling Tiansheng was startled. "Probably two or three pigs. If the cow is allowed, I'll get one. There are eight people in my family."
Meng Qidi nodded, "For eight people and pigs and sheep, there's no need to make it too big. About ten square meters will be enough."
In that era, there was no water from toilets like in later generations. It mainly relied on the fermentation of human and livestock feces.
After making four marks, Meng Qidi held out her hand, "Give me a pen and paper, and measure it with a ruler. Calculate the area, not the volume."
Ling Jinming was well prepared. He handed paper and pen to Meng Qidi and took out a tape measure from his pocket to measure.
He reported the area to Meng Qidi, who asked him to measure the distance between the pigpen and the figure she drew...
By the time he finished his work, the structural diagram in Meng Qidi's hand had already taken shape.
The couple finally managed to sneak a closer look, but the graph was filled with so many numbers that they were completely clueless and couldn't understand anything.
Ignoring them, Meng Qidi was not afraid of being robbed of her skills. She drew a diagram and calculated while explaining to Ling Jinming...
Half an hour later, the two stopped discussing and Meng Qidi handed him the blueprint.
"The structural drawings are out. Now we need to calculate the cost. If we don't use steel bars, we will need red bricks. In addition to river sand, we also need gravel. The cement has to be silicate cement. You can find out by asking the manufacturer. This is a movable cover for feeding materials..."
These are just the materials for making a biogas digester. She also needs to find a manufacturer to customize the ventilation pipe. It would be best if it were a hose, including a valve, since methane is a flammable gas after all.
It’s okay at home, she will pay attention to these things, but if they are really brought to the market, safety will be the first priority.
Meng Qidi followed Ling Xiao to buy cement and knew the price of a bag of cement. If she went to the factory, it would probably be cheaper. As for bricks, they could all be bought at the factory price.
The profit of a biogas digester is the difference between the prices. By estimating it, you can know the cost.
As soon as the price was calculated, the couple handed over handfuls of money, some in ten-yuan notes and some in five-yuan notes.
I haven't even taken labor costs into account yet...
Knowing that the couple were greedy for small gains, Meng Qidi didn't bother to argue. Fortunately, she just used the price of cement in the market...
Coming out of Ling Tiansheng's house, Ling Jinming was a little dissatisfied, "Sister-in-law, why did you let them do this? It's simply too much."
Not to mention that the cost of the labor has not been calculated yet, even the leather pipe stove costs money.
"Don't worry, you won't lose money. Did you go to the cement factory and brick factory with your brother Xiao last time? Do the people there still recognize you?"
If we don't let them do this, we will probably bargain for a lower price later.
