Chapter 170 Deep Sea Minefield
20, April 11.

The calm Pacific Northwest.

A submarine sailed quietly in this sea area.

The submarine is only 137 kilometers away from America's Guam base.

This is a medium-sized submarine with a displacement of about 2000 tons, which belongs to the shark brigade of the Luzon Navy sequence, but its sequence does not exist in official documents.

Even inside the Luzon Navy, many officers did not know the existence of this submarine force.

This is mainly to avoid leakage of secrets. Although soldiers who join the shark brigade do not need to be transformed into soldiers, they must be implanted with biochips to become new humans.

The new humans are the employees who have been implanted with biochips in Homo sapiens company, and these people are not all included in the sequence of spider web managers.

Therefore, Li Qingye gave these people a common name - new human beings.

New humans include ordinary employees implanted with biochips, web managers and soldiers.

Now the number of new humans in the Luzon army is rapidly increasing, and the same is true for Hongshawadi.

Obviously Homo sapiens has very limited trust in ordinary natural persons.

Especially within the military, as Homo sapiens equips more and more secret weapons, the risk of leaks is also increasing.

There are too many uncontrollable factors of natural people, so it must not be used.

For example, the sailors in this submarine are all new humans. Without a natural person, the possibility of leaking secrets is minimized.

This submarine is an upgraded version of the Mackerel class—the Tuna class submarine. This type of submarine continues the design concept of the Mackerel class. Apart from concealment, other performances are ordinary.

At this time, the mission of this submarine is to come here to lay mines.

I saw the submarine moored on a seabed with an average water depth of about 240 meters, opened the cabin at the bottom, and dropped a small submersible.

The submersible sank slowly until it touched the surface of the seabed mud and sand, and a slight silt was stirred up. The surrounding marine animals were also startled by the sudden uninvited guest and fled away from the submersible.

The pheromone transmitter on the surface of the submarine emits a pheromone command.

Soon on the surface of the submersible, a large number of genetically modified parasites emerged. These genetically modified parasites were similar to worms and earthworms. They swallowed the surrounding sediment with their mouthparts, and then spit out the sediment to the surroundings.

In this way, the submersible gets stuck in the sand a little bit.

As long as about 3 days, the submersible will be completely buried by sand.

Inside this submersible, it is equipped with 4 heavy oxygen torpedoes and 10 sea mines. The pheromone and sonar detection system it carries can effectively monitor sea areas with a radius of 50-80 kilometers.

This is equivalent to building a secret submarine silo here.

Within its monitoring range, it just covered part of the waterway of the American Navy.

As long as there is a need, this submersible can be activated to turn this piece of sea into a minefield.

Moreover, these submarines can communicate with each other through pheromones. Although the amount of information exchanged is limited, it can still be used to transmit instructions.

In addition, Homo sapiens' submarine fiber optic monitoring network is also spreading along the surrounding sea areas.

For example, near the Palau Islands at this time, another tuna-class No. 003 of the Shark Brigade was performing secret missions in this sea area.

Anyone who has read the topographic map of the Pacific Ocean will find that the east side of the Luzon Islands is the famous Luzon Trench and Luzon Basin.

Especially the Luzon Trench, with a depth of 6000 meters, has a huge impact on the laying of submarine optical cables.

Therefore, when arranging submarine optical cables, if the trench can be bypassed, it should be avoided as much as possible. Although optical cables can also be arranged in the trench, if it breaks, it will be very troublesome to repair.

In order to bypass the Luzon Trench, Homo sapiens chose to set up two main submarine optical cables from the northern waters of Luzon Island and the northern waters of the Maluku Islands.

At this time, Tuna 003 is laying out the submarine optical cable, which is the southern line that circles around the Maluku Islands.

Tuna 003 opens the hatch from the bottom and drops a submersible. This submersible is about the same size as the submersible equipped with torpedo mines. In fact, it is developed from the same basic module.

The entire submersible is about 50 tons. In order to avoid the pressure of water pressure, the interior adopts a nearly solid design, and the body structure design of deep-sea fish is added.

The limit water depth that this type of submersible can withstand is about 3753 meters.

The old-fashioned way of laying submarine optical cables has been eliminated by Homo sapiens.

The old-fashioned laying method requires the cooperation of ships, and requires the ships to stay nearby for a period of time. Construction in its own sea area is okay, and the high seas can barely be used, but once it is close to other countries’ sea areas or hotspot high sea areas, it is inappropriate. Not safe anymore.

So Homo sapiens updated the new technology.

This technique is called seabed directional growth technique.

The specific operation is very simple. First explore a route suitable for laying out submarine optical cables on the seabed, and then set up a node every 100 kilometers or so.

The submarine is the core component of the node.

But after the submersible buries itself deep in the sand layer, the internal directional growth system will be activated and begin to grow coral cables in a fixed direction.

As for how to ensure that the coral optical cable will not grow crooked, it is actually very simple, that is, pheromone induction.

Because in the early seabed terrain exploration process, a growth anchor weighing 150 kg will be placed on the determined route.

The growth anchor is a miniature version of the submersible, which can be inserted into the sediment layer of the seabed at 10 to 15 meters, and then continuously release pheromones to induce the growth of coral optical cables in a fixed direction.

Usually, such growth anchors are arranged every 1000 meters.

Coral cables will grow at a rate of 10-15 meters per day in the sediment layer with a depth of 300-500 meters.

This growth rate is actually due to the rapid soil-drilling ability of the transgenic coral polyp, especially in the soft sand layer, its chitin mouthparts can quickly swallow the surrounding soil and obtain part of the raw materials it needs. A honeycomb coral tube with a diameter of 10 to 12 centimeters is constructed.

And another kind of genetically modified coral polyps will start to generate fiber optic crystals in these coral tubes.

The submarine optical cable composed of biological optical fibers not only can carry a very high information throughput, but also has the ability of self-healing.

In each growth anchor and growth node, a lot of nutrients are stored, which is also an important factor to promote the rapid reproduction of coral polyps and the construction of optical fiber crystals and protective shells.

Under normal circumstances, the nutrient reserves of the growth nodes are enough to build a 400-kilometer submarine cable.

Now the submarine optical cable is only a connection between two nodes, and has not changed from a line to a network, so the remaining nutrients are a kind of reserve, which can be used for subsequent line expansion and line maintenance.

For the sake of confidentiality, each growth node is equipped with an automatic destruction system. Once any accident occurs, the node can be completely destroyed immediately.

In fact, the safety of the seabed is not bad.

Especially for seabeds with a water depth of more than 2000 meters, in addition to oil drilling platforms, submarines seldom dive below 1000 meters, and similar anchorages for ships are rarely carried out at depths of more than 500 meters. .

In this way, it is only necessary to avoid the drilling platform, and generally it will not be discovered or destroyed.

On the contrary, submarine optical cables in shallow water areas are much worse in terms of safety.
