100 square kilometers is 150,000 mu, with a yield of 1,500 kilograms of vegetables per mu, 225 million kilograms of vegetables can be harvested, even if the vegetables in Africa are cheap, they can be sold for at least 0.3 US dollars a kilogram, and the output value can be 67.5 million US dollars.

Obviously, Wang Fang's wishful thinking is that it is in a barren land, the land price is almost zero, the cost of plastic and film is also very low, the soil, the desert is there, manpower, African brothers can take care of the food, and even the clothes can be left unworn.

The estimated cost is more than $10 million, and the net revenue for the year is about $50 million.

Not counting making money by yourself, you can still feed a colonization town of 10,000 people, which is really fame and fortune. Why develop 100 kilometers inward instead of picking the seaside? Of course, it was because of Wang Fang's ambition to cover the desert with green. What kind of ambition is always at the beach?

However, the occupation of the strategic place of the seaside still has to be carried out, and in the future, he will be a water tyrant, and the sea water can be turned into treasure.

Ouyang Fen now worships Boss Wang infinitely, a person who can bring 0.5 to the Internet will be enough for MAN, and he can also force African brothers out of poverty with hardship, that is immeasurable merit. Of course, she doesn't understand agriculture, or the Internet 0.5 is more intuitive, after all, she has witnessed the rise of Qilang technology.

Of course, the hexahedral sail developed by Ouyang Fen before has also found a serious use - to use it as a means of transportation for African brothers, they do not have high requirements for speed, the ditch can pass small sailboats, the desert area can be seen at a glance, the wind is strong, and the speed will be a little faster. I wonder if this "ship of the desert" can run much faster than a camel.

In addition to being a water tyrant, Boss Wang can also be a ship tyrant, all the transport fleets are his, and he can also form a scale advantage, maneuvering between various unreliable regimes and forces, and the enlightened will invest a little more, and the unenlightened will invest a little less, which is quite flexible.

Of course, these small boats can't be wasted, and Boss Wang plans to develop a fishing industry in his colony town, and he still uses this hexahedron sailing boat. Such small boats have already proven their worth in China's coastal fishing towns. The most fearful thing about going out to sea to fish is that at the end of the day, the money for diesel fuel is in vain, but you can't catch a few fish.

There is no such problem with sails, and the operating costs are too low.

Boss Wang also has a killer feature - long-range remote-controlled unmanned sailing boats wandering overseas, and only when they find fish will the fishing boats be notified to chase and kill, which can save fishermen time spent wandering and drifting. He is afraid that he will not have money to invest now, so he initially plans to build 10,000 of these unmanned fishing boats and let them cruise in the Pacific and Atlantic.

Intelligence has become dominant in distant-water fisheries, and in addition to sonars in the fleet, natural fisheries radars - seabirds - are used. There are as many seabirds in the world as there are fishery radars. Drones on fishing boats can be used to detect the location of seabirds.

UAVs here can no longer use unpowered ******, because both landing and take-off are problems. Wang asked the aircraft designers to design a new electric twin-rotor ****** with reference to the US military's Osprey transport plane, and strengthen the streamlined fuselage, which began to glide after flying to an altitude of several hundred meters, and used the kinetic energy generated by the altitude drop to generate electricity, further increasing the ******'s time in the air.

The drone is designed to allow it to scan a 50-kilometre radius of the surrounding sea for a long period of time, and if it spots a seabird, follow it along.

In fact, Wang Bang didn't like this method of improving fishing efficiency on a large scale, because it would exacerbate the extinction of marine life, but ...... No way, this is business, if human beings are going to do this kind of immoral thing after all, then it is better to do it themselves. In the future, if countries around the world reach an agreement on fishing on the high seas, they can at least be sure that they are willing to refrain from fishing, which is definitely much more negotiable than those fishermen who rely entirely on fishing for their livelihood.

And he wanted to see for himself how marine life is overfished. These 10,000 fishing boats are also 10,000 pairs of eyes, and they will be gathered to his headquarters with scientific expeditions.

If the current rate of fishing continues, will there be a biological catastrophe?

According to ecologists' estimates, the most terrifying threat to marine life comes from the dissolution of carbon dioxide in the ocean, and the number of previous prehistoric mass extinction events has shown that the acidity of the ocean may be below the critical point of 7.8, and a certain iconic tenacious marine life will not be able to reproduce, and a super-massive mass extinction will occur.

Therefore, the current event of global fishing production reduction may be hiding the ecological disaster caused by large-scale human oil and coal extraction.

Once the temperature is right, plankton in the ocean will multiply on a large scale, and as soon as the sea life based on it begins to flourish. So it's hard to imagine that the reduction in production caused by overfishing is not the main reason, at least not the main reason.

Therefore, Boss Wang is still lucky, although my 10,000 fishing army has joined the global army of fishing, however, I have replaced oil with natural energy, which may bring more environmental benefits to reduce carbon emissions than the negative effects of fishing.

Some jellyfish don't even need plankton, and their parasitic algae can directly use sunlight to produce nutrients, forming a parasitic relationship with jellyfish, they are called "sunnylyfish", and when the sun is shining, they can fill their algae tentacles with the sky.

Wang Fang believes that jellyfish may be the basic food before the end of mankind in the future, because they have a stronger reproductive ability when the sea temperature rises, and now, in Japan, Taiwan and other places often occur "jellyfish tides", because of the relationship between the sea temperature.

However, many jellyfish are poisonous, including Chaotian jellyfish, and Boss Wang is a genetic technology controller, and he plans to gather a bunch of scientific researchers to breed non-toxic Chaotian jellyfish, using their properties that are not restricted by food as fish feed.

A 100-kilometre-long seawater canal can serve as an excellent fish farm. There is a kind of perverted fish with reproductive ability called "sunfish", a female fish can give birth to 300 million fish eggs, and sunfish is one of the few fish that feed on jellyfish, when the food is sufficient, Boss Wang's huge fishing ground will quickly give birth to cheap seafood.

Because the jellyfish is nourished by sunlight, it is equivalent to converting solar energy into biomass energy, which is part of desert agriculture and can be called a desert fishery.

Because of the demand for desert fishing, this ditch of Boss Wang does not allow ordinary boats to pass through guò, and their propellers that have not been specially treated will leak organic oil and pollute the water quality.

In 2013, there was a technology called the top ten biotechnology breakthroughs, called CRISPR-Cas9, the full name of CRISPR is "regularly spaced clustered short palindromic repeats", Cas9 is a protein that bacteria can cut into invading DNA to achieve defense purposes, this system is a technology discovered and patented by MIT and Harvard's Broad Institute.

Now scientists can use such technology to easily knock out and insert arbitrary base pairs, and Wang's real yàn chamber will also use this "third-generation gene editing technology" to knock out the toxic genes of the jellyfish.

When Qiu Zeyu, the second-generation secret agent, heard about Boss Wang's actions, his employer was completely stunned, and he couldn't understand what the other party was doing, CRISPR-Cas9? What the hell is Nima?

The secret agent said that Wang Bang's task to scientists was to find toxic genes, which scared Qiu Zeyu enough to think that the other party was going to poison him.

Begonia was afraid that Wang Zhan would make a mistake, so he seized another opportunity to come to the "Roy Jin Biochemical Room" and bitterly persuaded Wang Zhan not to do this.

Wang Fang was inexplicable: "What did I do?" It's been a long time since I've thought about your brother and sister, do you feel like you've been left out? ”

Begonia: "Are you looking for toxic genes trying to breed poisonous food to harm my brother?" ”

Wang Bang smiled dumbly: "Look at you nervous, don't think nonsense if you don't understand science, it's just ordinary research, I just talked to a few scientists, we are solving the problem of the flood of toxic organisms caused by humans, including jellyfish." Many poisonous organisms fill a gap in the biosphere because humans don't eat them, and we're looking at knocking out their toxic genes, or neutralizing their toxins, and then we can use them. ”

Begonia blushed and felt despised herself: "Really? ”

Wang Zhan: "Of course, I just spent 100 million US dollars to acquire a company that researches nanopore DNA sequencing algorithms, if I spend 100 million to send a lot of killers in order to deal with you, can you bear it?" If you want to deal with you, you also use the method of business warfare, that's interesting, you tell your brother, your cottage is very bad, I blush for you, and I'm afraid that I will be a moth. If this continues, I don't have to make any moths out of you, and you're going to make yourself a mess. ”

Begonia: "I'm stopping my brother, but it's a pity that he has to compete with you, I can't stop him." But...... The population of 100 million first-tier cities has more than 60 million in my brother's hands, does this mean that he won this round? ”

Wang Bang said: "It's not your ability to win in China, you have a good life, you have the ability to go to London and Tokyo to win a game against me." ”

Begonia said angrily: "Don't keep talking about you, I'm not in a group with him, I accidentally leaked your products, and then he begged for a copycat in vain, a stinking dead brother!" ”

Wang Fang: "Okay. And what, you ...... Most of your brother's contracts with municipal management are one-year contracts, and they don't seem to be too satisfied with your brother's products, but ours, next year your brother will know who is the winner. In fact, I have to thank your brother for forcing me out of a lock screen idea, which solved part of the problem of losing mobile phones for the public. This product has a great impact on the reputation of our brand.

Since then, our app user viscosity is huge, your brother, I inquired about your user retention rate, which can be described as hehe, people who really know how to think that my products will counterattack next year. ”
