Chapter 21 Open the door to a new world for the second brother
…
Wang Shouzhe didn't take these little incidents too seriously, but changed the topic to the main topic: "By the way, second brother, the live fish in your fish stall have the highest value, right?"
"Yes, in addition to spiritual fish, some of the best live fish are the most valuable. Perch, catfish, mandarin fish, bream, shad, and bream are all famous for their freshness and tenderness, and are quite popular among wealthy businessmen. When you like it, the only requirement is fresh food." Wang Shouyi frowned and said, "Uncle Liu's fishing fleet has live water tanks. After landing from the live water tanks, they need to be transported to Changning Acropolis overnight by special carriages, and we also need to do it in the shortest possible time. It will be delivered to the buyer inside. Even if it is used for a very short time, there will be many mistakes. Sixty to seventy percent of the ten percent will die. After death, the value will drop by half and it can only be sold as fresh fish."
Wang Shouzhe thought for a while and then said: "In this way, the cost of the transportation process and the mortality rate of live fish are the two keys. Solve these two problems, even if the fishing output does not increase, you can make a lot of extra money a year ."
The reason why he traveled around to inspect the family's various industries was because he wanted to see every aspect of the family's industry production. If he could use his modern earthly thinking to make some optimizations, he could increase the output of the family's property.
"If fourth brother can find a way to solve the problem of the death of live fish, it is conservatively estimated that an additional seventy or eighty thousand gold will be gained every year." Wang Shouyi couldn't help feeling distressed on his face, "The dead fish are all pure profit."
"It's hard to say now. I have to take a look at your original plan, second brother."
"Fourth brother, follow me." Wang Shouyi led Wang Shouzhe to the backyard of the other courtyard, where two carriages were parked. Different from ordinary carriages, they did not have passenger cars, but each had a large wooden barrel. , he said, "One of the carriages contains live water and fish, and the other carriage only contains live water. Every hour, part of the water in the fish barrel needs to be replaced. But even so, after a little more live fish, , will still cause death, I am already considering whether to add a carriage to carry running water, but the cost will increase a lot."
Wang Shouzhe's eyelids twitched as soon as he saw Wang Shouyi's method of transporting live fish. The number of valuable live fish that Uncle Liu could catch every day was not large, and at most it was only one or two thousand catties a day.
Such amazing means were used during transportation? These fish barrels are also unexpectedly crude. There is no aeration or filtration, only two words, change the water!
In order to change the water, a carriage was actually used to fill the water. This was not enough, Wang Shouyi actually planned to add another carriage?
But Wang Shouzhe also knows that this is really not Wang Shouyi's fault. Because this is a Xuanwu world, everyone is thinking about how to improve their cultivation level and how to improve their personal martial arts.
Of course, not all human elites do not study some natural subjects. It is just that even if those people have researched some results, they will keep it to themselves. All kinds of knowledge are strictly kept secret and difficult to spread outside.
This is not their fault. Even the knowledge developed by Wang Shouzhe will only be used for family secrets. It is unthinkable for him to spread it and benefit other families.
When Wang Shouzhe was working in his previous life, he was an unsatisfactory salted fish. He often went fishing with his friends during holidays and caught a lot of fish. He also bought an oxygenating pump to try to feed the fish and slowly eat them, but it turned out that only the fish was oxygenated.
He died just as quickly. After a little research and study, he understood some simple principles.
If you want to keep fish alive and eat them slowly, you must make your water tank meet three conditions.
The first is the amount of dissolved oxygen in the water. Fish need oxygen to survive, and the oxygen in the water is limited. The more fish in a bucket, the greater the oxygen consumption. This can be achieved by increasing oxygen.
The second step is to clean the water quality. Fish feces and food residues will produce ammonia and nitrite, and respiration will produce nitrogen. These are factors that cause fish death and can be solved through water changes, filtration and other means.
Then there is the temperature. The higher the temperature, the greater the activity of fish, the more oxygen they need to consume, and the more toxic substances such as ammonia produced will increase. Therefore, it is also very effective to keep the water quality at a relatively low temperature.
After combining these three points, the two entered Wang Shouyi's study. After thinking for a while, Wang Shouzhe drew a simple sketch on paper. The top layer of the wooden barrel containing the fish was filtered, and the filtered water fell into the wood in the shape of rain.
In the bucket, this uses the simplest principle of dripping oxygen.
And in the simplest terms possible, he and Wang Shouyi popularized the principles of oxygen and toxic substances.
Wang Shouyi has been working in the fish stall for more than ten years, and he soon understood Wang Shouzhe's principle. He suddenly realized: "When my fourth brother said this, I suddenly understood a lot. In the past, the elders in the family just passed down the message to change the living water.
, The reason is that fish need vitality in the water. If there is not enough vitality, the water will become stagnant, and the fish will die. What the fourth brother means is that using the raindrop method can increase the vitality in the water, but I have never thought about it."
"This is from ancient books. It's hard to say whether it has any specific effects. I have to do a few more experiments and comparisons with my second brother." Wang Shouzhe nodded secretly. Just be energetic. It's better to understand than the confusing word "oxygen".
"The fish will spit out the dead gas after eating it, and the excess feces in the water will produce poisonous gas. The poisonous fecal gas in the water will be filtered out through the cotton cloth layer, crushed charcoal, and gravel layer. The water will be non-toxic, and the fish will naturally not die. Why didn't I think of that?
?”
Wang Shouyi became more and more excited as he talked: "Also, the hot and cold conditions mentioned by the fourth brother are quite reasonable. The colder the weather, the less dead fish will be when transporting live fish. In summer, more live fish will die. It turns out that fish are more active in hot weather, so they need
The more vitality it has... No wonder transportation during the day is not as good as at night! If you add some storage ice to the water..."
The theory taught by Wang Shouzhe seemed to have opened a door to a new world for Wang Shouyi. Many things that had been puzzling before were suddenly figured out.
"Second brother, as long as you understand, you can let the craftsmen make a few small devices to try out." Wang Shouzhe looked at the sky and said, "It's getting late. I have other things to deal with, so I'll leave first."
As the patriarch, Wang Shouzhe is not here to invent and create. What's more, it's easier said than done. If he is asked to make those things with his own hands, he may not be able to do a good job.
As long as Wang Shouyi understands the principle, he is enough to undertake the next work.
"Fourth brother, don't leave in a hurry." Wang Shouyi held on to him, "It's rare for you to come to the fish stall once, and the second brother hasn't treated you well yet. We will have dinner at [Baiweixuan] at noon. The live fish in that restaurant are all from us.
All the dishes on offer are delicious. There are several things that I haven’t figured out yet. The siphon effect drainage type you mentioned? What is the principle of using a pump to add vitality to the water tank? How to use the principle of a pump to let the water flow?
Walk high..."
Come on!
Wang Shouzhe listened to his "100,000 whys". Although he was a little confused, he also knew that it was a good thing. Wang Shouyi had been running the fish stall for many years. If he could really immerse himself in this way, the fish stall business would get better and better in the future. This can be regarded as a good thing.
He has made a great contribution to the family.
In Changningwei, Wang's fish stall is not the only one, but there are more than ten aristocratic families running the fish stall business. Especially the Liu family and the Zhao family, both are bigger than the Wang family.
The better your own fish stall does, the more wealth you create, and at the same time it actually squeezes the living space of your competitors.
Therefore, Wang Shouzhe spent more time and had a good "enlightenment education" with Wang Shouyi. Both the siphon effect and the manual pump require pipes. The use of pipes in the world is quite rough, with only bamboo pipes, ceramic pipes, and copper pipes.
There are several types, but they are barely enough.
It doesn’t matter if the hand pump cannot be built for the time being. Use the simple siphon principle to suck out the bottom water and ask the clerk to manually pour water into the filter layer. In this way, the transportation volume of a carriage will be greatly increased, and the live fish rate will also be greatly increased.
Wang Shouyi was fascinated by what he heard. Even when he was having lunch at Baiweixuan, he grabbed Wang Shouzhe and asked endlessly.
"Second brother, is this Baiweixuan really one of the best restaurants in Changningwei?" Wang Shouzhe ate the dishes from Baiweixuan and felt that the taste was average, but it was better because of the high quality of the ingredients.
Of course, the level of seasoning is still better than that of the cooks of the Wang family, but there is still a big gap between the taste and that on earth.
"Fourth Brother, I ate 32 coppers and 73 dimes for this meal..." Wang Shouyi's face turned dark and he kept shouting, "This is all the private money that Brother Yu has worked so hard to save. How dare you still serve such delicious dishes?"
Not satisfied?"
Wang Shouzhe touched his chin. The feeling of difference was probably due to the sodium glutamate pot. In his previous life on earth, MSG and chicken essence were everywhere in the food world, which had already raised the threshold of deliciousness in his soul memory.
To a very high degree.
If MSG can be produced, can it also become an industry?
