protect our patriarch

Chapter 21 Open the door to a new world for the second brother

……

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

"Yes, in addition to spirit fish, some high-quality live fish are of the highest value. Bass, anchovies, mandarin fish, tuna, anchovies, and anchovies are all famous for their freshness and tenderness, and are popular among wealthy merchants in aristocratic families. I like it, the only requirement is freshness." Wang Shouyi frowned and said, "Uncle Six's fishing fleet has living water tanks. After landing from the living water tanks, they need to be transported to Changning Acropolis by special carriage overnight, and we also need to do so in the shortest possible time. Send it to the buyer. Even if it takes a very short time, there will be many mistakes, [-] to [-]% of the ten will die, and after death, the value will drop by half and can only be sold as fresh fish.”

After some thought, Wang Shouzhe said: "In this way, the cost of transportation and the lethality rate of live fish are the two keys. By solving these two problems, even if the catch and output do not increase, a lot of extra money can be earned in one year. ."

The reason why he traveled around and inspected the various industries of the family was to see every link of the production of the family industry. If he could make some optimizations with his modern earthly thinking, he would be able to increase 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 extra seventy to eighty gold dollars every year." Wang Shouyi couldn't help but feel distressed on his face, "The dead are all pure profit."

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

"Fourth brother come with me." Wang Shouyi led Wang Shouzhe to the backyard of the other courtyard, where two carriages were parked.Unlike ordinary carriages, they do not have a passenger car, but each has a large log barrel, he said, "One of the carriages is filled with living water and fish, and the other is only filled with living water. Every hour , it is necessary to replace part of the water in the wooden bucket for the fish. But even so, if there are a little more live fish, it will still cause death. I have already considered whether to add a carriage to fill the living water, but the cost of consumption will be reduced. A lot more."

As soon as he saw Wang Shouyi's means of transporting live fish, Wang Shouzhe's eyelids twitched. The number of valuable live fish that Uncle Six can catch every day is not much, and at most it is only one or two thousand catties a day.

How to use such amazing means when transporting?These fish buckets are also unexpectedly simple. There is no oxygenation or filtration at all. There are only two words, change the water!
In order to change the water, a carriage was even used to fill the water.This is not enough, Wang Shouyi is planning to add a carriage?
But Wang Shouzhe also knew that it was not Wang Shouyi's fault.Because this is a Xuanwu world, everyone is thinking about how to improve their cultivation realm and how to improve their personal strength.

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

It's not their fault, even the knowledge that Wang Shouzhe has researched will only be used for the secret use of the family, and it would be impossible for him to spread it out to benefit other families.

Wang Shouzhe was an unsatisfactory salted fish when he went to work in his previous life. He would often go fishing with friends during holidays. He caught a lot of fish. He also bought an oxygen booster pump to try to feed the fish and eat slowly, but it turned out that it was only aerobic fish. He died very quickly. After a little research and study, he understood some simple principles.

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

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

The second is to clean the water. Fish excrement and food residue will produce ammonia and nitrite, and respiration will produce nitrogen. These are all factors that cause fish to die, which can be solved by changing water, filtering and other means.

Then there is the temperature. The higher the temperature, the greater the activity of the fish, the oxygen that needs to be consumed will increase, and the production of toxic substances such as ammonia will also increase.Therefore, keeping the water quality relatively low is also very effective.

After combining these three points, the two entered Wang Shouyi's study. After thinking for a while, Wang Shouzhe 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 wood in the form of rain. In the barrel, this uses the simplest principle of dripping oxygen.

And in simple words, Wang Shouyi 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 quickly understood the principle of Wang Shouzhe. He suddenly realized: "I suddenly understand a lot after hearing what the fourth brother said. In the past, the elders in the family just said that the living water needs to be changed. The reason is that the fish need to drink the vitality in the water. If the vitality is not enough, the water will become stagnant water, and the fish will die. The fourth brother means that using the rain dripping method can increase the vitality in the water, but I never thought about it."

"This is according to the ancient books. It's hard to say whether it has any effect or not. The second brother has to do a few more tests and comparisons." Wang Shouzhe nodded secretly.

"Fish eats living gas and exhales dead gas. Excessive feces in the water produce poisonous gas. Through the cotton cloth layer, broken charcoal, and gravel layer, the poisonous fecal gas in the water is filtered out. If the water is non-toxic, the fish will naturally not die. Why didn't I think of that? ?"

The more Wang Shouyi said, the more excited: "Also, the cold and hot conditions mentioned by the fourth brother are also quite reasonable. The colder the weather, the fewer the deaths of live fish, and the more live fish die in summer. It turns out that the fish are more active in hot weather, so they need to The more alive you are... No wonder it's not as good to transport during the day as at night! If you add some hoarding ice to the water..."

The theory taught by Wang Shouzhe seems to have opened the door to a new world for Wang Shouyi. Many things that were inexplicable in the past have been figured out all at once.

"Second brother, if you understand it, you can ask the craftsman to make a few small devices to try it out." Wang Shouzhe looked at the sky, "It's getting late, I have other things to deal with, so I will say goodbye."

As the patriarch, Wang Shouzhe did not come to invent inventions.What's more, it's easier said than done, and letting him handle those things with his own hands may not be able to do well.

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 held on to him, "It's rare for you to come to the fish stall once, and the second brother hasn't treated him well. We ate at [Baiweixuan] at noon, and the live fish in that restaurant were all from us. The taste of all kinds of dishes is unparalleled. The second brother still has several places that I don't understand. What do you mean by siphon effect drainage? What is the principle of using a pump to increase the vitality of the water tank, and how to use the pump principle to let the water flow walk high..."

Got it!

Wang Shouzhe listened to the "[-] whys" in his mouth. Although he was a bit big-headed, he knew that it was a good thing.Wang Shouyi has been running fish stalls for many years. If he can really immerse himself in this way, the business of fish stalls will get better and better in the future, which can be regarded as a great contribution to the family.

There are not only Wang's fish stalls in this Changning Wei, but more than ten aristocratic families running the fish stall business.Especially Liu's and Zhao's are bigger than Wang's.

The better their own fish stalls are, the more wealth they create, the more they actually squeeze the living space of their opponents.

Therefore, Wang Shouzhe spent more time, and then had a good "enlightenment education" with Wang Shouyi.Both the siphon effect and the hand pump require pipes. The use of pipes in this world is quite rough. There are only bamboo pipes, ceramic 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 transportation volume of a carriage is greatly increased, and the rate of live fish is also greatly increased.

Wang Shouyi was so fascinated by it that he even grabbed Wang Shouzhe and asked him chatteringly when he was eating at [Baiweixuan] at noon.

"Second brother, are these Baiweixuan really the best restaurants in Changning Wei?" Wang Shouzhe ate the dishes of Baiweixuan, and suddenly felt that the taste was average, but the quality of the ingredients was better.

Of course, the level of seasoning is still higher than that of the Wang family chef, but there is still a big gap between the taste and the earth.

"Fourth brother, this meal ate 32 big coppers and 73 coins..." Wang Shouyi's face turned black, and he shouted injustice, "This is all the private money that Brother Yu has worked so hard to save, how can you still pay for such delicious dishes? Not satisfied?"

Wang Shouzhe touched his chin, and the sense of drop was estimated to be the pot of sodium glutamate. When he was on the earth in his previous life, MSG and chicken essence filled every corner of the food world, and he had long been reminded of the threshold of deliciousness in his soul's memory. to a very high degree.

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