Chapter 31: Submarine stealth

Quantum radar technology is very advanced, it can scan at very long distances, and even pass through large obstacles such as mountains, but it consumes a lot of energy points. If the omni-directional scanning at the maximum distance is turned on, the energy point consumed will be astronomical, and the energy point of the drone cannot support it at all.
However, when the quantum radar reduced the scanning range to a very small range, and was used to connect to the network world, and uploaded and downloaded various data on the network, although the quantum radar ’s consumption of energy points is also huge, Yan Fei has already It can bear it, which is why Yanfei uses quantum radar to connect to the network.
The assisted brain is connected to the network through quantum radar. The upload and download speed of various data is very fast, so after downloading the language data of each country, it has parsed out the language knowledge of all countries in the world with super computational power, making it able to Read all the literature in the world.
After that, I assisted the brain to continue downloading various documents on the Internet, and stored these documents in the brain database. Then, the data was classified and summarized, and then the technology contained in it was developed to supplement its own technology tree.
Although the language is quickly parsed out, it does not mean that other technologies can be quickly parsed out. Because all the rules of the language can be searched on the Internet, there is no secret. As long as enough language usage methods are collected, the language technology can be analyzed and mastered thoroughly.
Although scientific and technological knowledge can also be found on the Internet, most of them are very general, only general introductions, and many specific details are deliberately hidden. Therefore, to assist the intellectual brain to analyze the complete technology contained in it, it can only be achieved through powerful Computational power to simulate details that have been deliberately hidden, thereby deducing the complete technology.
Although the assisted intellectual brain is very advanced, it does not have the function of a hacker. It cannot break through the network restrictions and forcibly obtain the confidential files of others, so it can only download free materials through normal channels, or registered members can obtain confidential information that can be downloaded by paying a fee. This makes the literature that can be downloaded by the assisted intellectual brain quite simple, and a large number of technological faults require it to use computing power to perform simulation experiments.
It is precisely because of such restrictions that the assisted intellectual brain's analytical action on science and technology is destined to be long-term and not necessarily effective. However, Yan Fei does n’t have any special needs for technology now, so let the assisted intellectual brain download the data on the network by himself. He is not concerned about this matter for the time being.
The energy of the three-level drone has reached 100,000 points, which is enough to support the drone to fly for five hours at maximum speed and the longest flight distance can reach 5000 kilometers. At economic cruise speeds, the longest flight time can even reach ten hours.
If the drone is in the standby state, just turn on the quantum radar to connect to the network for file transfer, and use the assisted brain to perform a large number of calculations, the energy point will be enough to support two hours. So when the drone is not out, every night after 10 o'clock, he uses the energy point for network connection and scientific analysis to avoid wasting energy points.
晚上 On the sixth night, Yan Fei lay on the bed and activated the drone in the canyon. The drone quietly rose up the cliff, and then flew to the east at the height of the treetops. This canyon is very close to the sea, less than twenty kilometers, just a few minutes, the drone came to the sea.
Previously, when the drone's quantum radar was turned on at full power, it scanned a 500-kilometer topographic map and stored this map in a brain-assisted brain database. Now the drone uses this map to navigate, basically There is no need to worry about the situation of trek, it is very easy to reach the destination.
During the flight, because of the quantum radar, the drone avoided everything that could expose it. The quantum radar scans a semi-circle 1 km ahead, so that the consumption of energy points is controlled to an acceptable level.
Seeing the vast sea, Yan Fei was excited in her heart.
He flew the drone tonight to test the drone's stealth capabilities. Because the drone is hiding in the canyon, it may still be found by satellites in the sky, so he must find a hidden place for the drone, and the bottom of the sea is the best place for the drone to dock.
The coastline that Yanyan Fei chose was very remote. No one appeared during the day, and at night, it was very unpopular.
The drone flew to the sea silently. After it flew two kilometers from the coastline, Yan Fei thought about it, the drone's nose sank, and it suddenly slid into the sea.
As soon as the drone entered the seawater, it began to deform. Its slender and straight wings were bent and tilted to the rear, and the four weapon racks under the wings were automatically retracted and retracted into the belly. The entire body changed Become a streamlined type with more submarine stealth advantages. After the drone's body deformed, the large propeller at its rear began to rotate rapidly, pushing the drone forward quickly in the sea water.
When the drone entered the sea, Yan Fei didn't feel the pressure of the seawater, nor did he feel any change in temperature. Everything is just like flying in the air. Then he discovered that because of the light, the drone can directly observe the object at a limited distance on the ocean floor, but the sound collection was not affected, but the distance was farther and clearer.
燕 Under Yan Fei's control, the drone began to sneak under water. With the propeller behind it, its speed was still very fast. But compared with the speed of drones flying in the air, the speed at the bottom of the sea has slowed down significantly.
According to the data displayed by the auxiliary brain, the maximum speed of the drone on the sea floor is only 150 kilometers. Although this speed is incomparable with air flight, compared to other ships, this speed has left them far behind.
For the first time, using a drone to sneak under the sea, Yan Fei feels very novel. Just like in the air, the drone's movements can be done like arm instructions. The drone made rapid progress on the ocean floor. He was surprised to find that the quantum radar could also be used on the ocean floor, but because of the sea water, the maximum detection range of the quantum radar was shortened to 100 kilometers. But as far as the seafloor is concerned, this detection range of 100 kilometers is enough.
量子 Under the scan of the quantum radar, the topographic map of the sea floor is presented in Yan Fei's mind exactly, and then recorded by the auxiliary intellectual brain as the basis for navigation. Although the sea floor is dark, with the topographic map scanned by the quantum radar, the drone is like walking on the road during the day. It is difficult to get lost.
Here is Huaxia's offshore. The average depth of the sea does not exceed 100 meters. However, the whole sea seems a bit empty. Over the years, fishermen have no fishery resources because of overfishing by fishermen. At least in Yan Fei's quantum radar, few big fish were found. But as he marched towards the deep ocean, various marine life also gradually increased.
By the time the drone went one hundred kilometers into the ocean, the depth of the ocean floor had exceeded 500 meters. At this depth, Yan Fei found that it was very difficult for the drone to continue to dive, and the auxiliary intellectual brain also began to issue a warning. He immediately knew that the limit depth of the drone was reached, which was 500 meters deep on the sea floor.
So the drone no longer continued to dive, maintaining this depth toward the east at high speed. At this time, there were already a lot of marine life. From time to time, you can find several big fish swimming by the drone. The sea floor was dark, and Yan Fei could not directly observe these marine life. The marine life he saw was all displayed on quantum radar. Where there is no light, quantum radar becomes Yan Fei's eyes.
The drone quickly traversed a coral reef, and suddenly, a shark came out from under the coral reef. The shark showed sharp teeth and bited the drone's wings. Yan Fei was startled, and one side of the unmanned body avoided the attack of sharks. Then the drone moved forward quickly, who knew that the shark actually caught up.
As soon as Yunyan Fei's heart moved, the drone made a turn in the front and turned its direction, facing the shark that was chasing. The shark didn't know why the drone stopped suddenly, it still chased after it frantically, and then saw the flash of the drone's nose flash, and a big hole appeared in the shark. Then the fire flickered again, and the shark's body suddenly became torn apart. Blood stained the surrounding sea water, and the broken body attracted the fish around.
It turned out that Yan Fei saw the sharks chasing after him, and activated the vulcan artillery of the drone's nose to attack. A few artillery shots killed a large shark that dominated the ocean. After the drone entered the sea, although the missile system was no longer available, the 730 artillery at the nose could still be used. Compared with when in the air, in addition to the inability of the 730 artillery to use incendiary bombs and shorter attack distances, the power of 30 mm bullets has not been reduced by half.
However, Yan Fei's disappointment happened. Although he killed a huge shark, he didn't increase his merits in the virtual control screen. He used a quantum radar to scan and found a sea fish larger than this shark ten kilometers away, so the drone quickly moved forward, rushed to that area, the cannon roared, and killed the sea fish. As a result, Similarly, the merit points of the drone have not increased, and are still zero.
In the face of such a result, Yan Fei was dumbfounded. At the first level of the drone, you can get meritorious points by attacking large stray dogs with peas ~ EbookFREE.me ~ Now you can kill sharks and large marine fish that are much larger than stray dogs. There is no meritorious point? Is it because the level of the drone is increased, the upgrade difficulty becomes more difficult, and there is no merit point when attacking some low-level targets? If this is the case, Yan Fei's desire to use the large amount of creatures in the ocean to obtain meritorious points will be completely lost.
The worst attack method of drones now is the 730 Vulcan gun of the nose. All the calibers of the bullets are 30mm. These bullets are so powerful that ordinary people simply cannot afford them. Even if it only touches a part of the body, ordinary people will die instantly. Moreover, the firing of the bullet is carried out by the ammunition ignition. Yan Fei cannot control this power, so each attack of the bullet is carried out with full force. That is to say, Yan Fei cannot obtain the merit points by attacking the non-critical parts of the enemy or reducing the power of the bullet, just like the steel ball bullets of the past. So will I have to kill 10,000 enemies in the future so that the drone can upgrade again?
However, Yan Fei immediately woke up from this emotion, and he will definitely think of a way to upgrade the drone. He believes that there is no way out of the sky. Since he can get a drone clone, he will definitely find a solution to the problem.
In the first and second levels, the upgrade of drones can only rely on killing large animals and humans to obtain meritorious points. At the third level, large animals can no longer contribute to the drone. In the midst of it, a mysterious force limited the way the drone could upgrade, leading Yan Fei to a wonderful journey he had never thought of before.
