Just three days later, all the four sand drills were put into operation, and more than 700 white razor clams could be dug out every day.

    When the mountain of razor clams appeared, everyone was shocked.

    Even those who already know the efficiency of the sand drill can''t help losing their voice when they see the real object for the first time.

    This is the charm of industrialization. With the help of good organization and machines, individual labor efficiency will be greatly improved.

    Only more than 20 people operating four machines can easily dig out more than ten tons of white razor clams in the sand in just four or five hours. In this era of backward productivity, it''s just incredible.

    The anxiety caused by the lack of food on the island has also been swept away, and everyone is very confident that everyone will be able to eat in the coming long winter.

    And it''s full.

    Of course, there are not only razor clams on the beach, but also many other kinds of conches and seashells, which have been caught by sand drills.

    Most of the workers who operate sand drills are experienced fishermen. Even those who have lived on Odin island for many years know for the first time that there are so many strange conches and seashells on the beach.

    The output did not meet expectations, mainly due to the lack of experience and tacit cooperation of workers. However, with the improvement of proficiency, the output will be further improved. Renault estimates that in a few days, the output will be stable at more than 800, and it is impossible for more than 1000.

    In addition, Miss consul does not intend to let the brand-new sand drill work for 30 days and then completely idle, which will be a great waste. She plans to fight for two months in a row to clean up the beaches of the nearby islands.

    Her ultimate goal is 60000.

    Enough for the whole island for a year.

    The truth that "if you have food in your hand, don''t panic in your heart" is also known to the people of other countries.

    As for whether the razor clam will become the most hated food for the residents of the tidal islands in the future, Miss consul doesn''t care. Anyway, it''s not for her to eat it for a year.

    Subsequently, the government affairs department recruited nearly 300 people from the residents with scallop meat as compensation. According to the plan made in advance, the government simultaneously started the work of cleaning and drying scallop meat, building warehouses, and manufacturing storage pots.

    The labor standards set by young girls themselves are also quite attractive, especially in a time of food shortage.

    Even a woman who is in charge of drying shellfish can get 1kg dried shellfish, equivalent to 3kg fresh shellfish. She also provides free lunch and dinner every day.

    As long as adults are willing to work hard, they can get at least 3kg scallops.

    After the news came out, most of the residents of Hongshi Town, the only town on the island, and two nearby villages came to sign up, with a total number of nearly 600.

    Most of them come from families that are short of food on the island. If the administrative department does not provide this opportunity, I am afraid most of them will not survive this winter.

    Finally, at the instigation of the girl, the government office gave priority to the most difficult group of civilians.

    And Renault has begun to solve the second problem - fuel.

    This problem is very important, because the thermal magic engine will be developed in three months at most. As a new type of ship power, it will consume a lot of fuel.

    So during this period, Renault needs to store enough fuel.

    In addition, from next year, he plans to gradually use stronger and more durable masonry buildings to replace traditional wooden buildings, especially in towns.

    Because the hidden danger of wooden buildings is too big, once the fire is on fire, if it is not put out in time, the fire will spread rapidly, half of the city will turn into fly ash, and the civilians will be killed and injured seriously.

    Such tragedies happen frequently in this world. Renault doesn''t want his hard-working territory to meet the "burning city" in the future.

    In order to build a town with brick and stone buildings, it will consume a lot of bricks and stones. In other words, it also needs a lot of fuel to burn bricks.

    What kind of fuel is suitable?

    Wood?

    Of course not.

    Although the calorific value of wood in this world is higher, the island itself is not big, and there are not many forest resources. Even if all the forests on the island are cut down, I am afraid it will not meet the demand.

    And wood is not suitable for ship fuel. Who has ever seen wood burned by ship power?

    What''s more, forests have a greater role. In the special environment of islands, if there is not enough forests, there will be extremely serious ecological disasters, which will lead to the island no longer livable. Easter Island on earth is the best negative teaching material.

    If wood is not used, what alternative fuel is used?

    Coal burning?

    On the earth, coal promoted the first industrial revolution. The light and heat released when it burned lit up the road of human civilization.

    But, I''m sorry, this is an alien world, not the earth. There is really no such thing as "coal".When Renault was sure that the coal really did not exist, he was also surprised for a long time.

    In the long history of the earth, after entering the Carboniferous, thanks to the emergence of lignin, plants have strong enough bones, and can easily grow tens of meters or even hundreds of meters high. From this time on, forests began to expand wildly.

    But the evolution of bacteria failed to keep up with the pace of plants. When the plants died, bacteria could not decompose lignin, and a large amount of organic carbon was deposited in the strata, and finally coal was formed.

    It is also in the Carboniferous period that a large amount of coal appeared on the earth. During this period, the coal reserves accounted for more than half of the total coal reserves of the earth.

    In other words, the emergence of coal is the victory of plants, but also the failure of bacteria.

    But in the alien world, the roles of plants and bacteria have changed.

    This time, the bacteria evolved faster. Their strong decomposition ability made it too late for most of the carbon elements to deposit. Finally, they successfully killed the coal.

    However, although there is no coal, the alien bacteria have left another substitute - dirty soil.

    Dirty soil is a kind of pure black soil. In the sun, the surface will reflect bright light like grease. It widely exists in the strata, and its burial depth is generally not deep, and its reserves are not low.

    However, people from other countries do not intend to use it at all.

    Because in addition to carbon, there are a lot of impurities such as silicon in the sewage soil, and the content of carbon is significantly lower than that of coal, so it is not easy to burn, and the calorific value is not as good as that of charcoal.

    In addition, there is another important reason, dirty soil is very dirty.

    Under the joint action of magic energy and soil flora, the carbon elements in the contaminated soil were not transformed into carbon elements, but mixed in the soil in the form of compounds.

    This compound is stable at room temperature and has a slightly earthy smell, but when it burns, it emits a pungent smell, which makes people shy away. The awesome bacteria in the

    are also powerful.

    The unique marine ecological environment has created another kind of flora. Like their terrestrial brothers, the marine flora has also successfully dried up plants in the speed race of evolution, to the hell of coal.

    Due to the lack of oxygen environment, the carbon element in the ocean remains more. In the long years, the plant debris is finally transformed into another form of compound.

    When these carbonaceous compounds combine with the ubiquitous sea water, amazing changes have taken place.

    Combustible ice appeared.

    To be exact, black ice!

    Black ice can''t be burned directly. It needs to be heated to remove water before it can be used as fuel. Black ice can also produce peculiar smell when burning, but it is much smaller than dirty soil.

    In the shallow sea area of the mainland, black ice exists widely. The black ice is mixed with mud and spreads all over the sea floor. In some places, there is even a layer of black ice whose thickness is difficult to measure.

    In some coastal areas of foreign lands, the local residents have a long tradition of using black ice, and these areas often have a vast area of shallow water black ice.

    When the sea water ebbs, people rush to dig black ice in the sea mud as fuel for cooking or heating in winter.

    Although because of the peculiar smell, families with a little surplus will choose charcoal, the poor people who can''t afford charcoal don''t mind.

    Therefore, when encountering fuel problems, Renault naturally thinks of black ice.

    In the tidal islands, shallow black ice also exists, and the reserves are extremely amazing.

    The only drawback is that the black ice layer is buried near an island more than 20 kilometers away, and it will only come out of the water after the ebb tide, so the time limit for direct mining is relatively short.

    At this time, on a small sailing boat more than 20 meters long, Renault, with Angela, Muse, Lena, Sansha, Ronald and 20 members of the island guard, is heading for black ice island.

    For the sake of black ice, the three giants of territory come out.

    Well, the name "black Iceland" just came out an hour ago.

    As for the island protection team, this is the first armed force on the island. The captain is moss and the vice captain is Ronald. Together with the two, the total number is only 25.

    Renault offers a very good salary. As long as he joins the island protection team, his salary is more than enough to support a family of four. He also has a special allowance when carrying out the task. In case of casualties, his pension is also very generous.
