Wang Shouzhe didn't pay too much attention to such episodes, but turned the topic to the main topic: "By the way, second brother, the value of live fish in your fish stall is the highest, right?"

"Yes, apart from the spirit fish, there are some of the best live fish that are the most valuable. Perch, eels, mandarin fish, squids, shad and shad are all known for their freshness and tenderness, and are quite popular with wealthy merchants, and the only requirement is to be fresh. Wang Shouyi frowned and said, "There is a live water tank on the fishing fleet of the sixth uncle, and after going ashore from the live water tank, it needs to be sent to the Changning Acropolis overnight in a special carriage, and we also need to deliver it to the buyer in the shortest possible time." Even if it takes a very short time, there will be a lot of mistakes, and six or seven out of ten will die, and after death, the value will drop by half and can only be sold as fresh fish. ”

After a moment's thought, Wang Shouzhe said: "In this way, the cost of the transportation process and the lethality of live fish are the two keys. Solving these two problems can make a lot of extra money in a year, even if the catch does not increase. ”

The reason why he traveled around the family industry was to see every aspect of the production of the family industry, and if he could make some optimizations with his modern earthling's thinking, he could improve the output of the family property.

"If the fourth brother can find a way to solve the death of live fish, it is conservatively estimated that there will be an additional seventy or eighty dollars per year. Wang Shouyi's face couldn't help but feel distressed, "Those who die are all pure profits." ”

"It's hard to say now, I have to look at your original plan, second brother. ”

"The fourth brother comes with me. Wang Shouyi led Wang Shouzhe to the backyard of the other courtyard, where two carriages were parked. Unlike ordinary carriages, they did not have a passenger car, but each had a large barrel, and he said, "one of them was filled with live water and fish, and the other was filled with only live water." Every other hour, a portion of the water in the bucket is replaced. But even so, if there are a little more live fish, it will still cause death, and I am already considering whether to add a carriage of live water, but the cost of this consumption will increase a lot. ”

As soon as he saw Wang Shouyi's means of transporting live fish, Wang Shouzhe's eyelids twitched, and the number of valuable live fish that the sixth uncle could catch every day was not much, at most it was only one or two thousand catties a day.

These fish barrels are also unexpectedly simple, there is no oxygenation, no filtration, just two words, change the water!

In order to change the water, a horse-drawn carriage was even used to load water. This is not enough, Wang Shouyi is actually ready to add another carriage?

But Wang Shouzhe also knows that Wang Shouyi is really not to blame. Because this is a Xuanwu world, everyone is thinking about how to improve the cultivation realm and how to improve their personal strength.

Of course, not all human elites do not study some natural sciences. It's just that even if those people have researched some of the results, they will cherish themselves, and all kinds of knowledge are strictly kept secret, and it is difficult to spread them to the outside world.

This is not to blame them, even if it is the knowledge researched by Wang Shouzhe, it will only be used by the family secrets, and it is not even thought of letting him spread it to benefit other families.

Wang Shouzhe belonged to the ideal salted fish when he went to work in his last life, and he often went fishing with his friends on holidays, caught more fish, and also bought an aeration pump and tried to feed the fish to eat slowly, but it turned out that the aeration fish died quickly, and he understood some simple principles after a little data search and study.

If you want to feed the fish and eat slowly, you have to meet three conditions in your tank.

The first is the amount of dissolved oxygen in the water, the survival of the fish needs oxygen, and the oxygen in the water is limited, the more fish in a bucket, the greater the oxygen consumption, which can be achieved by increasing oxygen.

The second is the cleanliness of water quality, fish feces and food residues will produce ammonia and nitrite, and respiration will produce nitrogen, which are all factors of fish death, which can be solved by changing water, filtration and other means.

Then there is the temperature, the higher the temperature, the greater the activity of the fish, the more oxygen needs to be consumed, and the production of ammonia and other toxic substances will also increase. Therefore, it is also very effective in keeping the water quality relatively cold.

After combining these three points, the two entered Wang Shouyi's study, Wang Shouzhe thought for a while, and drew a simple sketch with paper, the top layer of the round wooden barrel containing the fish was filtered, and the filtered water fell into the wooden barrel in the form of rain, which used the simplest principle of drip water oxygenation.

And in as simple words as possible, he popularized the principle of oxygen and toxic substances with Wang Shouyi.

Wang Shouyi has been working in the fish stall for more than ten years, and soon figured out Wang Shouzhe's principle, and he suddenly realized: "Listening to what the fourth brother said, I suddenly understood a lot. In the past, the elders of the family only passed down to say that they wanted to change the living water, because the fish needed to eat the living gas in the water, and if the living gas was not enough, the water would become stagnant water, and the fish would die. What the fourth brother meant was that using the raindrop water method could increase the vitality in the water, but I didn't think about it. ”

"This is what it looks like in ancient books, and it's hard to say whether it has any effect, and the second brother has to do a few more tests and comparisons. Wang Shouzhe nodded secretly, let's be alive, it's better to understand than the awkward word oxygen.

"The fish eats the living gas and spits out the dead air, and the feces produce poisonous gas in the water, and the fecal poisonous gas in the water is filtered out through the cotton layer, broken charcoal, and the gravel layer, and the water is not toxic, and the fish will not die. Why didn't I think of that?"

The more Wang Shouyi said, the more excited he became: "There is also a lot of truth in the hot and cold conditions that the fourth brother said, the colder the day, the fewer the live fish will die, and the more live fish will die in summer." It turns out that the hot fish are more active, so the more vitality they need...... No wonder it's not as good as it is at night......!

The theory taught by Wang Shouzhe seems to have opened the door to a new world for Wang Shouyi, and many things that he couldn't figure out before were figured out at once.

"Second brother, you can understand it, you can let the craftsman make a few small devices first and try more. Wang Shouzhe looked at the sky, "It's not early, 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, and it may not be possible to do a good job of letting him do those things with his own hands.

As long as Wang Shouyi understands the principle, he is enough to undertake the next work.

"Fourth brother, don't be in a hurry. Wang Shouyi pulled him and didn't let go, "It's rare for you to come to the fish stall once, and the second brother hasn't entertained him yet." At noon, I dined at [Baiweixuan], the live fish in that restaurant are all served by us, and all kinds of dishes taste unique. The second brother still has a few places that I don't understand, what is the principle of using a pump to add vitality to the water tank, and how to use the principle of the pump to make the water go to a higher place......

Come on!

Wang Shouzhe listened to the "100,000 whys" in his mouth, although he was a little big, he also knew that it was a good thing. Wang Shouyi has been running a fish stall for many years, and if he can really immerse himself in this, the business of the fish stall will get better and better in the future, which can be regarded as a great contribution to the family.

In this Changningwei, there is not only the Wang family's fish stall, but more than ten families running the fish stall business. In particular, the Liu family and the Zhao family are both larger than the Wang family.

The better your own fish stall does, the more wealth you create, but in fact, it also squeezes the living space of your opponents.

Therefore, Wang Shouzhe spent more time, and then started "enlightenment education" with Wang Shouyi. Both the siphon effect and the hand pump require pipes, and the use of pipes in this world is quite rough, with only a few kinds of bamboo pipes, pottery pipes, and copper pipes, but they are barely enough.

It doesn't matter if the manual pump can't do it temporarily, use the simple siphon principle to suck out the bottom water, and ask the guy to manually pour water into the filter layer. In this way, the volume of transportation in a horse-drawn cart has increased dramatically, and the rate of live fish has also increased significantly.

Wang Shouyi was fascinated when he heard it, and even when he was eating at what [Baiweixuan] at noon, he grabbed Wang Shouzhe and asked endlessly.

"Second brother, is this Baiweixuan really the best restaurant in Changningwei?" Wang Shouzhe ate those dishes of Baiweixuan, and suddenly felt that the taste was average, but it was only better because of the quality of the ingredients.

Of course, the level of seasoning still exceeds that of the Wang family's cooks, but there is still a big gap between it and the earth in terms of taste.

"Fourth brother, I ate 32 big copper and 73 slots for this meal...... Wang Shouyi's face darkened, and he cried out for injustice, "This is all the private money that the foolish brother has worked hard to save, such a delicious dish, you are not satisfied?"

Wang Shouzhe touched his chin, and the difference was estimated to be a pot of monosodium glutamate, and when he was on the earth in his previous life, monosodium glutamate and chicken essence were filled in every corner of the food world, and the threshold of deliciousness in his soul memory had long been raised to a high degree.

If you can get MSG out, can it also become an industry?
