Just allowing fishermen to dive is obviously not the ultimate Downing's ultimate standard, and the power of the breathing apparatus is also that it can provide underwater oxygen to hydrogen fuel cells, making the super submersible qì possible.

Downing has had the strange idea these days, developing an underwater carriage that allows divers to hide in enclosed carriages and be dragged by large fish equipped with propellers to advance on the bottom of the sea. No matter how good the divers are, they will start to be anesthetized by nitrogen at about 100 meters, think of the sailors that Lincoln sacrificed in order to salvage the King-class cruiser.

While a depth of 100 meters is only a gathering point for entry-level marine life, the concept of shallow sea is about 500 meters, and only being able to cover such a deep sea area is a major breakthrough in the fishing industry. Only by completely breaking through the range of activities of ordinary fishermen can new fishery resources be obtained.

Fishermen who dive are terrific and dive to 50 meters, and Downing's submarine carriage will be able to make ten times more profitable than others, and perhaps ten times more mass, because the sea creatures will certainly hide deep in order to escape the fishermen's attacks.

The reason for the design of the carriage is to improve the work efficiency, at that time, each submarine coachman is equipped with two "seahorses", the carriage also dragged two fish boxes, one fish box is fully loaded, then let the seahorse automatically pull to the surface fishing boat, the coachman continues to work at twice the speed of the water, so that until the end of the day, the efficiency is several times higher than the continuous back and forth.

Downing also equipped the undersea coachman with a rigid transparent fishing cover, which can be thrown at the bottom of the ocean like a harpoon, but at a slower speed, relying on the refractive index to be exactly the same as that of seawater, so that the target is completely unresponsive. With the same sonar help, no school of fish in a semi-circular area 100 meters long in front of it can escape tracking.

And the crabs, lobsters, squid and the like who act alone, have to rely on the eyesight of the trench coachman.

This black technology is an absolute black technology, if it is used in the sky military, it is a super submarine that does not need to be exposed to the surface for ventilation, so this technology cannot be passed on, but Tang Ning uses it for special fishing vessels. And the hired coachman will not know the details of the technique. They will only be overwhelmed by this god-like technology.

This technique may be even more lucrative than sonar fishing and longlining, as it directly opens up a ten-fold fishing area and is in shallow waters with the highest concentration of marine life. It's a place where marine sediments come together, feed plankton and are the foundation of the entire ecosystem.

With such a lucrative business, you don't have to care about the cost at all, you can design the carriage to accommodate two people, have a companion when you work, chat while fishing, and watch the wonders of the sea while working. After the success of the experiment, Tang Ning personally went to the sea to fish, and constantly caught the never-before-seen big crabs and lobsters, which was really enjoyable.

It's fun to even watch others catch fish, and once they surface, everyone gathers around to see the harvest, and then men, women and children rejoice. Everyone couldn't help but touch a handful of crabs and lobsters fluttering with their paws, and the joy of the harvest was overflowing on everyone's faces.

At the same time, Downing's royal marine biologist also began to study the marine life around Japan in depth in order to formulate a more reasonable fishing policy, this time without consulting others, because it is impossible for others to go down to such a deep fish, which is an absolute monopoly business.

When Tang Ning was eating "Okonomiyaki" with Sister Tsukishima at the night market of "The Kitchen of the World", a small episode occurred. Because he was afraid that people would recognize him, he wore a mask and was taken away by the police, and the police at the police station didn't recognize him yet, well, he had to call "to ask for his relationship" and directly called Lord Shimazu Saibin, a member of the Japanese Foreign Ministry, whose relationship with him had deteriorated.

Could Shimazu-sama please put a man from Ethiopia from the Osaka Public Security Bureau's xx police station named Leonardo? Cage's guy let go, this man is ostensibly an ordinary tourist, but in fact he is the governor of Ethiopia.

Ethiopia is on the Red Sea, is the African continent of the country to communicate with the outside world relatively early, even Christianity dominates among its citizens, recently the African Development Bank is using Downing's vacuum siphon pump technology in its territory of the Blue Nile River to build a new type of irrigation and power generation integrated equipment, so Downing casually gave himself the title of Ethiopian Governor, and used Leonardo? Cage's pseudonym.

Ethiopia was originally a comfortable traditional monarchy, but it was overthrown by the African club because it was not accustomed to using the power of the African military alliance, and this kind of foreign country was of course not in the eyes of the Japanese, so when he saw Downing's fake passport, he did not approve of it, and Downing had to call them directly to the foreign affairs commissioner.

Shimazu still wonders, isn't Ethiopia a black African country? How do you listen to the Osaka public security officer's reflection that the color of the "suspect" is not quite right?

Since the Windsor Emperor said it, Shimazu couldn't say anything, and the curious public security officer actually received a call from the boss of the Ministry of Foreign Affairs and asked him what he was doing in Ethiopia.

Leonardo? Mr. Cage said about his recent research: "The Blue Nile in Ethiopia is the world's longest river, the largest source of water for the Nile, and I am responsible for designing hydroelectric irrigation equipment for the Blue Nile. ”

Mr. Cage explained the principle of the vacuum water pump, and the police were amazed, and this person explained the parameters of the water pump so carefully that it seemed that he was at least an engineer, and could not be a foreign criminal. In fact, even if he is a criminal, the Ministry of Foreign Affairs can only let him go.

At the time of parting, a new Japanese who loves to chase stars finally recognized Emperor Windsor, and knelt down with a plop and called "Mr. Windsor". It made Tang Ning very embarrassed and said, "Isn't everyone equal now?" Why is there still a strange etiquette in Japan? ”

The young Osaka said excitedly, "Yes, they are all equal, but Mr. Windsor is the only one I want to salute you, and the last one I want to salute, because it is you who make all Japanese equal." ”

"Alright! Great work! Goodbye! Tang Ning smiled and put on a mask, held hands with Yuehime and left the public security bureau.

A childish Japanese man left behind him was muttering excitedly, why did the Ethiopian hydraulic engineer become Mr. Windsor again?

Osaka is not good to stay, and he has to go to a rural place with few people to play, and Tang Ning asks Tsukihime.

Immersed in the boundless years, Tsukihime replied casually, "Well, let's go to the house of a shiitake mushroom supplier at our sushi restaurant, they are in a village near Kyoto, where the scenery is pleasant and quiet. ”

Kyoto's mountain people had an unexpected artistic appreciation, they cut down the trunk of the oak tree and dried it for two years, and then used it as a log for cultivating shiitake mushrooms.

Twenty or thirty shiitake mushrooms can be grown on one log. With a completely natural production method, the family can harvest nearly 10,000 high-end ingredients every year without needing anything. They also call the dark ones "rain mushrooms" and the white ones "day mushrooms".

The mushrooms are especially beautiful because of the delicate patterns on them, which resemble hand-carved patterns. The mountain people of Kyoto are truly extraordinary, and the joy of the harvest once again infects people with happiness, and there is a little bit of artistic enjoyment. In the past, cutting logs was a very strenuous task, but now this work has been greatly reduced by the birth of the chainsaw, and the happiness has skyrocketed.

The happiest thing is that the mountain people don't know the Tang Emperor, and they ask him to work together, which is really happy. The Tang Emperor was most afraid of the "etiquette" of the Japanese towards him.

It's amazing that the mountain people have a very simple sense of environmental protection. The oak tree does not die when it is cut down, because the mountain people will leave a trunk more than one meter high, and in the spring of the next year, new branches will grow, and this process has been repeated for hundreds of years, and the trunk of the oak tree grows strangely, leaving a hollow hole.

Some of the hundred-year-old oak trees have holes that can hold the next adult. The tree cave has become a natural home for animals, and the toads love this rainproof and windproof, warm and humid environment, as if they are the little pets of the mountain people.

If they all care about the environment as much as the mountain people of Kyoto, Downing would not have to become an intercontinental warlord to maintain order on the high seas with power. Downing instantly fell in love with Kyoto, and that little resentment towards the Japanese now disappeared without a trace.

What makes a happy life even sweeter is that the mountain people have learned to adopt bees. Bees also like to build nests in tree holes, because of the wind and rain, when the rainstorm comes, the homes outside the cave are damaged, so living in tree holes has a survival advantage. The mountain people used the oak trees again, built them into tree holes, and coated the inner walls with honey, which attracted bees during the breeding period to come and build nests.

When the horse chestnut tree blooms, the crown of the whole tree is fully blooming more than ten meters high, and the fragrance of the flowers attracts wild bees and butterflies within two kilometers. If you want to steal a little lazy, the little bee will choose to build a nest under the horse chestnut tree.

It's not wrong to be lazy, even if you are in the hands of the mountain people, the life of the bees is still good, every year before the winter, their honey room is filled with honey, and the mountain people will keep enough rations for the hive, and will not rush to kill them all.

This kind of lifestyle of harmony between nature and man is really incomparably beautiful, and Tang Ning talked about life and production with the mountain people, which was very pleasant.

Downing wanted to taste the honey he had gotten by himself, so he decided to hire the best beekeeper to be a technical consultant, and he wanted to make 10,000 beehives and place them in the primeval forest centered on Kyoto, one every two kilometers, anyway, Japan has a high forest coverage.

The technical consultant was dumbfounded when he learned of the boss's plan, and the boss said shyly: "I have many friends, so I can digest them myself." ”

Honey is not readily available, it is a relatively expensive sugar, and it is an excellent condiment, whether it is eaten directly or as a condiment, it is appetizing.

Downing will set up a beekeeping team, the first round, use the method of mountain people's technical advisers to lure bees to build nests, the second round, expand the location of the 10,000 trap boxes into 10,000 apiaries, and raise 200 swarms of his mother in an apiary (insect experts say this is the upper limit of an apiary), as long as each swarm of bees produces one kilogram, my Tang's apiary array can produce 2 million kilograms of honey per year.

According to the current statistics of metro supermarkets, the most profitable way to sell is a small bag of about 15 grams, which can be sold for a huge income of one pound per kilogram, which is comparable to the price of a nigiri sushi sold by a Tsukishima girl. After the second round, our boss Tang created another 2 million pound super industry.

In order to get the best source of honey, Downing decided to put these 10,000 apiaries in Japan's primeval forests, which required the cooperation of the Japanese government, so he unceremoniously waved his pen and stated in the application plan that he would donate half of the profits from these 10,000 apiaries to the Japanese scientific team for research on forest ecosystems.

Downing's annual donation to the British Museum is only 100,000 pounds, and with Downing's control of labor costs, most of the 2 million income is profitable, and Japanese ecological scientists will get nearly 1 million pounds of super funding, not to mention the study of Japan's forest ecosystem, which can run all over the world
