The calcium supplement plan for fishing grounds cannot be completed in one day. This is a phased work. The first stage takes seven days to complete, and the scope is the continental shelf area covering the entire fishing ground.

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

The continental shelf depth of the Daqin Fishery is about 110 meters on average, which is a high-quality seabed terrain with different widths, but it is not far apart. From 180 kilometers to 200 kilometers, the average slope is very small, only about 0.2.

This is the place where calcium supplementation is needed. In addition to the exposed local bedrock, most of the areas are covered with sediments such as mud and sand. It is a fertile soil for the growth of seaweed and aquatic plants, and it is also the place with the most serious calcium deficiency.

The special boat was operating slowly, and Qin Shiou had to follow him all the way, because he was worried that if they took the wrong path, they would be troublesome to drag the anchor dragged on the seabed to the coral waters.

So in the past few days, except for entertaining his father-in-law and mother-in-law, Qin Shiou lies on the beach to read books. Of course, this is just for acting. In fact, he is using the consciousness of the sea god to monitor the two ships.

After absorbing the "Dragon Breath Fragrance" obtained by the wrist of the old man Kaufu, although the heart of the sea god did not change qualitatively, the quantitative change was not small. His consciousness of life under the sea became clearer and clearer, and his impact on the ocean became greater and greater.

Seeing Qin Shiou lying on the beach reading every day, the fishermen were full of confusion. After Shaq went to read, he came back and said that Boss was reading "Marine Biology", Yan Gun went to read and said that the captain was reading "Marine Geology". Then they discussed and guessed that Qin Shiou was planning to take the college entrance examination?

Last time, Qin Shiou asked how to deal with the fishing ground to restore its previous fertility, and a group of fishermen were confused and could not express their opinions. At that time, Qin Shiou was anxious and said that we lacked high-education talents. He planned to take the master's degree in marine majors in a prestigious university by himself.

This was originally something Qin Shiou said casually, but the fishermen took it seriously now. Shaq and others also enthusiastically contacted the enrollment methods of various prestigious schools.

Qin Shiou didn't know these things. These days he followed two boats to carefully check the bottom of the fishing ground, and found many strange things that he had not noticed before.

Since he obtained the Heart of the Sea God, Qin Shiou has controlled the consciousness of the Sea God to travel through the fishing ground almost every day.

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

With the company of two ships these days, he was not so lonely and had the patience to cruise the seabed.

First of all, Qin Shiou discovered a hot spring under the sea. These hot springs were located at the end of the continental shelf, and there were several cracks under the sea that were dozens of kilometers long. A steady stream of hot sea water emerged from here.

Qin Shiou searched and found that this kind of undersea hot spring is not uncommon on the seabed. On the contrary, the higher the latitude, the easier it is to find this thing.

There are countless mysteries on the seabed. Humans probably don’t have one percent of their understanding of it. For example, oceanographers have not yet studied what’s going on.

What is now recognized is that there is crust lava under the hot spring, and the magma that surging without breaking through the seabed rock formations boils the water.

But what is confusing is that many of the hot springs were found to be located in the undersea volcanic belt, but in a very peaceful area. In addition, in the past few years, the United States' scientific research ships pierced the seabed of the hot springs.

The machine has been deep into the earth's crust for dozens of meters, but no magma is found, so this explanation is a bit unreasonable.

After Qin Shiou noticed the location of this hot spring, he carefully observed the surrounding situation and then found some delicate soil-like substances.

This material texture looks like soil, but it has a variety of colors. In fact, this is the precious subsea metal sludge.

The existence of metal slurry is another basis for overthrowing the magma of hot springs, because not all hot springs have such things nearby, only a small number of them exist. Only a small number of hot springs with metal slurry can be explained by the magma below.

Qin Shiou learned about it. Metal sludge is a kind of soft sludge rich in various metals formed by sludge rich in various metals formed by mixing with deep seabed soil with deep seabed soil.

This kind of soft sludge has great strategic value, but it is difficult to develop. First, it is located in the deep sea and the other is that it is surrounded by hot springs, which cannot be touched by manual means, and it is unreliable to use machinery to dig deep seas, so this resource has been put on hold.

The temperature of the hot spring is very high, but there is no shortage of life around it. Qin Shiou saw some red clams, sea crabs, blood-red tubeworms, oysters, mussels, crabs, shrimps, etc. not far from the hot spring.

In addition, there are some hydra creatures that are similar to dandelions around the hot spring, which naturally include worms, starfish and anemones.

For some reason, the red clams and sea crabs around the hot spring are both very large. I wonder if it is because there are no big fish who like to get close to this place. Anyway, although they are not very large in size, they are the most red clams with the size of a small pot lid, which is amazing!

In addition to the hot spring, Qin Shiou discovered something even more strange, that is a lot of glassy substance!

The location of these substances is very concentrated, just in a small basin in the middle of the continental shelf. It has been a long time since the small basin has been covered by sea mud. This time, it was a special ship passing by, and then the treasures were pulled out with anchors.

Qin Shiou learned about it online that this glass-like substance is glass, with a texture similar to that produced by humans now, and its name is submarine glass.

Until now, according to people's surveys, undersea glass is just a specialty of the Atlantic Ocean. As for why so many undersea glasses appear in the Atlantic Ocean where granite is difficult to find, this is still an unsolved mystery...

The small basin is not large, maybe only more than 40 acres, and it is full of large pieces of seabed glass. These glasses are very similar to the silicate glass produced by people. Of course, the transparency is not that high, but it is also considerable and has good light transmission.

Moreover, these glasses are particularly bright and colorful, some are light red, some are light blue, and some are snow-white. It seems that someone forged glass on the bottom of the sea and left some waste.

Seeing these undersea glasses, Qin Shiou suddenly thought of the Crystal Palace, the Dragon King’s residence in Journey to the West.

Thinking of the Crystal Palace, Qin Shiou suddenly had an idea, could he use these large pieces of glass to build a palace on the bottom of the sea? (To be continued)
