The fighting on the monthly ticket list and the recommended ticket list is very fierce. Please ask your brothers and sisters for help. The eggshell will work hard and continue to explode****


    The fishing ground calcium supplement plan can not be completed in one day. This is a phased work. The first stage takes seven days to complete, covering the continental shelf area of the whole fishing ground.


    The continental shelf is the natural extension of the continent to the ocean and is usually considered to be a part of the land. The sea area at this location is a shallow sea area. The terrain is flat. Its seabed is covered by sedimentary layers. It tilts to the deep sea from the edge. Finally, the land base extends into the deep-sea plain.


    The average depth of the continental shelf of Daqin fishing ground is about 110 meters. It belongs to high-quality seabed terrain. The width is different, but the difference is not far. From 180 km to 200 km, the average slope is very small, only about 0.2.


    This is the place to supplement calcium. In addition to the exposure of local bedrock, most areas are covered with mud, sand and other sediments. It is not only a fertile soil for the growth of algae and aquatic plants, but also the place with the most serious calcium deficiency.


    The special ship worked slowly, and Qin Shiou had to follow all the way, because he was worried that if they took the wrong way and dragged the anchor towed on the seabed to the coral waters, it would be troublesome.


    So these days, in addition to entertaining his father-in-law and mother-in-law, Qin Shiou lay on the beach reading books. Of course, this is only for acting. In fact, he is monitoring the two ships with Poseidon consciousness.


    After absorbing the "dragon birthday fragrance" obtained from the wrist of the little old man kaufu''s wife, although there was no qualitative change in the heart of the sea god, the quantitative change was not small. His sense of life at the bottom of the sea became clearer and clearer, and his influence on the ocean became greater and greater.


    Seeing Qin Shiou reading on the beach every day, the fishermen looked puzzled. After shack went to see it, he came back and said that the boss was watching marine biology, and the smoker came back and said that the captain was watching marine geology. Then they discussed and guessed that Qin Shiou was going to enter the University?


    Last time Qin Shiou asked how to deal with the fishing ground in order to restore the past fertility. A group of fishermen were full of fog and water dog farts. At that time, Qin Shiou was worried and said that we were short of highly educated talents. He planned to go to a famous university for a master''s degree in marine science.


    Qin Shiou said it casually, but the fishermen are serious now. Shack and others are also enthusiastic to contact the enrollment methods of various famous schools.


    Qin Shiou didn''t know these things. He followed two ships to carefully check the bottom of the fishing ground these days, and found many strange things he hadn''t noticed before.


    Since gaining the heart of the sea god, Qin Shiou has controlled the Sea God consciousness to walk through the fishing ground almost every day.


    However, it''s too lonely to wander on the seabed alone. Qin Shiou doesn''t have the patience to stay for a long time. Instead, he likes to wander in the middle waters, because most important economic fish live in the middle waters.


    With the company of two ships these days, he is not so lonely and has the patience to cruise on the seabed.


    First of all, what Qin Shiou found was a submarine hot spring. These hot springs are located at the end of the continental shelf. There are several cracks on the seabed with a length of tens of kilometers, and a steady stream of hot sea water comes out from here.


    Qin Shiou searched. This undersea hot spring is not rare at the bottom of the sea. On the contrary, the higher the latitude of the cold sea area, the easier it is to find this thing.


    There are countless mysteries at the bottom of the sea, and I''m afraid humans don''t understand it by one percent. For example, an undersea hot spring, oceanographers haven''t studied it clearly.


    Now it is generally accepted that the explanation is that there is crustal lava under the hot spring, which is the magma that surges and does not break through the seabed rock strata, which burns the water.


    However, it is puzzling to find that many hot springs are not located in the submarine volcanic belt, but in very quiet areas. In addition, American scientific research ships have punctured the seabed where the hot spring is located a few years ago.


    The machine has been deep into the earth''s crust for tens of meters without finding magma, so this explanation is a little unreasonable.


    After Qin Shiou noticed the location of the hot spring, he carefully observed the surrounding situation, and then found some fine earth like materials.


    This material looks like soil, but it has different colors. In fact, it is precious undersea metal ooze.


    The existence of metal ooze is another basis to overthrow the theory of hot spring magma, because not all hot springs have such things near them, only a few of them, and hot springs with metal ooze can be explained by magma at the bottom.


    Qin Shiou learned that metal ooze is a kind of ooze rich in various metals formed by the deep magma of the earth seeping into the deep stratum along the cracks of the seabed crust, dissolving the salts and metals in the magma and turning them into ore bearing solution. Under the action of high temperature and high pressure in the deep stratum, it is sprayed to the seabed with the seabed hot liquid and mixed with the deep seabed soil.


    This kind of soft mud has great strategic value, but it is difficult to develop. First, it is located in the deep sea. Second, it is surrounded by hot springs, which can not be touched manually. It is unreliable to use machinery for deep-sea excavation, so this resource has been shelved.


    The temperature of the hot spring is very high, but there is no lack of life around. Qin Shiou saw some red clams, sea crabs, blood red tube worms, oysters, mussels, crabs, shrimp and so on not far from the hot spring.


    In addition, there are some Hydra creatures similar to dandelion around the hot spring, including worms, starfish and anemones.


    I don''t know why. The red clams and sea crabs around the hot spring are very big. I don''t know if it''s because no big fish like to be close to this place. Anyway, although their survival number is small, the largest red clams are the size of a small pot cover. It''s amazing!


    In addition to hot spring, Qin Shiou found a more strange thing, that is, a lot of glassy materials!


    These materials are concentrated in a small basin in the middle of the continental shelf. Over time, the small basin has been almost covered by sea mud. This time, special ships passed by and pulled out these treasures with anchors.


    Qin Shiou learned on the Internet that this glassy material is glass. Its texture is similar to that of ordinary glass produced by human beings. It is called undersea glass.


    Until now, according to people''s investigation, undersea glass is only a specialty of the Atlantic. As for why there are so many undersea glass on the Atlantic seafloor where it is difficult to find granite, it is still an unsolved mystery


    The area of the small basin is not large. It may be only more than 40 mu. It is full of large pieces of underwater glass. These glasses are very similar to the silicate glass produced by people. Of course, the transparency is not so high, but it is also considerable and the light transmittance is very good.


    Moreover, these glasses are particularly gorgeous and colorful. Some are light red, some are light blue, and some are snow white. It seems that someone forged glass on the seabed and left some waste products.


    Seeing these underwater glass, Qin Shiou suddenly thought of the Crystal Palace, the residence of the Dragon King in his journey to the West.


    Thinking of the Crystal Palace, Qin Shiou suddenly had an idea. Can he use these large pieces of glass to build a palace at the bottom of the sea?
