Super Invincible Battleship

Just when Yan Fei was studying the powerful data of the drone and was full of joy, the huge roar of the helicopter came from the distant sky. It turned out that the white light vision from the upgrade of the drone was finally discovered by the island self-defense force military base in the distance. , They began to send helicopters to find out what happened.

The drone had just been upgraded, and Yan Fei was in the moment of joy in his heart, so he had no idea of ​​shooting down the helicopter. He quickly put the remaining rare earth metal wooden boxes and gold bricks on the ground into the general space. The drone upgrade absorbed these raw materials, but there were still rare earth metals remaining, but Yan Fei didn't know how much of these remaining rare earth metals were, so he randomly put them into the general space. And there is still more than half of that pile of gold left. Yan Fei initially estimated that the previous pile of gold was about 30 tons, and after ten tons were used, there are still about 20 tons left. And the rusty part of unknown origin has completely disappeared, which makes him a little regretful.

However, Yan Fei was immediately relieved. This time he came to the island country, not only did he get his revenge, he killed Dahe Ryoko, Dahechang, and Dahe Heroes, and he also gained a lot of merit points, which made the drone upgrade to level 4, making himself With a surge in strength, he finally has the ability to protect himself. In the end, they even obtained the remaining 20 tons of gold and other rare earth metals from the Dahe family, which can be regarded as a complete victory. As soon as the rusty part disappeared, he didn't know what it was anyway, so he wouldn't be too distressed.

Yan Fei quickly cleaned up the ground without leaving anything behind. He saw the helicopter in the distant sky getting closer and closer. With a thought, the cockpit of the drone's nose automatically opened upwards, and he jumped into the cockpit, comfortably Sit comfortably on the driver's seat and close the cockpit. Then the drone lifted off quickly and flew towards the sea to the east without making a sound.

Shortly after the drone flew away, the helicopter of the Japan Land Self-Defense Force landed at the place where the drone was upgraded, and a few soldiers of the Japan Self-Defense Force jumped out of the helicopter. These soldiers inspected the land carefully. In the end, apart from the traces of some small trees and weeds being crushed, there were no clues, let alone why there was a dazzling white light...

Yan Fei controlled the drone to fly at high speed on the sea, and found that the maneuverability of the drone has been greatly improved, and various operations can be performed at will. In comparison, the drone at the third level is like a child. Although it can achieve perfect control effects, but because of the incomplete development of the body, many actions cannot be performed, or fear of problems with the body. . A level 4 drone is like an adult man, with a well-developed body, well-developed muscles and bones, and can easily perform various difficult movements. It was only at this time that the extraordinary strength of the drone was truly demonstrated.

On the surface of the sea, the UAV flew up and down flexibly with Yan Fei's mind as if it had life, accelerated and decelerated, flew up and down, like an arm command. In Yan Fei's perception, the drone can "see" the outside situation anywhere on the body, which gives Yan Fei a full range of unobstructed perspectives.

During high-speed flight, thanks to the powerful all-round viewing angle, Yan Fei can clearly "see" everything around him through the drone, even farther and more clearly than he can see with his own eyes. According to his estimation, even at an altitude of 30,000 meters, he can clearly see the small words on a newspaper on the ground through the drone, provided of course that there is no cloud cover.

This upgrade not only improves the drone's "seeing" ability, but also improves its "listening" ability. The sound within a radius of two kilometers can be "heard" by the drone and collected. for analysis.

The improvement of these two abilities,

It makes the UAV not only "see" farther and clearer, but also "listen" farther and clearer. In addition, the upgraded quantum radar of the UAV makes the UAV truly have the magic of clairvoyance and ear wind in myths and legends. ability.

After the drone was upgraded to level 4, the virtual control screen did not display the data changes of the auxiliary brain, but in Yan Fei's test just now, it was found that the computing power of the auxiliary brain had been greatly improved, and the increase was at least More than 5 times. After he sent more complicated instructions to the assistant brain, the assistant brain could complete them accurately in an instant, allowing him to perfectly control level 4 drones and better utilize the combat capabilities of drones.

After the computing power of the assisted brain has been greatly improved, the technological deduction function attached to the assisted brain has also been greatly improved

upgrade, greatly speeding up the speed of assisting the intelligent brain to analyze and deduce technology. With this improvement, Yan Fei will be able to obtain more high-tech in a shorter period of time, which will contribute to his career.

The auxiliary intellectual brain actually has another function, which is the enlightenment of knowledge. The last time he relied on this enlightenment function, he learned three foreign languages ​​​​in an instant, and his proficiency was ranked first in the world. After this upgrade, he originally wanted to try this enlightenment function again, but the auxiliary brain still didn't have any instructions on how to use this function, which made Yan Fei dare not try it lightly. The painful experience last time made him have lingering fears about this function. Although his strength has improved again, he can't guarantee that his brain will not be overwhelmed by the huge knowledge.

Although the strength of the upgraded drone has been greatly enhanced, it still has no invisibility and can still be detected by various radars, which makes Yan Fei extremely regretful. He could only let the drone fly close to the sea at low altitude, and use the blind spot of the radar to avoid being tracked by others. Because of this concern, he couldn't let the drone fly freely at an altitude of 30,000 meters for the time being.

Yan Fei continued to test the various data of the drone. With a thought in his mind, the drone made a huge sonic boom, and then began to fly at supersonic speed. He saw the drone flying at high speed close to the sea surface. A huge white line appears to follow. The drone with the fastest speed of 3 times the speed of sound is so fast that it appears one kilometer away in an instant, which is more than three times faster than the third-level drone.

Yan Fei experienced the thrill of the drone's high-speed flight, and suddenly had a thought, and the drone showed extremely high maneuverability, changing from high-speed flight to stationary in an instant, and then suspended on the sea. Then the drone turned around and dived to the bottom of the ocean. As soon as the drone dived into the seabed, the body began to deform, from the most air-flying aerodynamic layout to the most submarine-sneaking streamlined layout.

As soon as the drone entered the sea, all the eleven weapon racks under the fuselage retracted into the body, and a torpedo launch pipe appeared directly under the fuselage. In this pipe, a torpedo ready to launch appeared. This torpedo is the torpedo version of the aim-120 air-to-air missile, but its power is only 80% of the previous one.

The drone sank to the bottom of the sea, began scanning with quantum radar, and soon found a huge reef. Yan Fei aimed at the reef in the distance and began to launch torpedoes. Under the guidance of the quantum radar, the torpedo was quickly launched towards the reef, and a long string of bubbles was brought out from the tail.

Twenty seconds later, the torpedo hit the reef with a dull explosion that shattered the reef into several pieces. Yan Fei was not very satisfied with the attack power of the torpedo, but it was much better than he could only attack with the Vulcan Cannon before. He tested again, and after consuming 8 torpedoes, he finally got the torpedo attack data: the fastest attack speed is 200 kilometers per hour, the longest attack distance is 5 kilometers, and the maximum attack depth is 400 meters.

The submarine-launched torpedo of this aim-120 air-to-air missile version is not very powerful, and it can't even pass the torpedo ranking in the world. The UAV already has the ability to attack in the deep sea, which can be regarded as a huge breakthrough.

After testing the submarine torpedo system, Yan Fei began to test the Vulcan cannon of the drone, but the result disappointed him. The power of the Vulcan cannon was exactly the same as before, and there was no increase. However, after having a torpedo that can be used in actual combat, the lack of Vulcan Cannon is not on his mind. Next he began to test the drone's sneak data on the ocean floor. Half an hour later, the sneak data was also summarized: the maximum dive depth is 600 meters, the fastest sneak speed is 200 kilometers, and the furthest detection distance of the quantum radar on the seabed is 150 kilometers.

To Yan Fei's regret, he killed many huge marine creatures during the test, but he still didn't get merit points. In other words, marine life, as before, cannot allow drones to gain merit points. But it doesn't matter, with the level 4 drone, he has a lot of opportunities to get merit points, and I believe that the upgrade speed of the level 3 drone will not be slower than that of the level 3 drone.

When the drone is flying in the air, it is silent and there is no sound. But when it dived into the sea and dived in the sea, it started to make a sound. This sound is not small enough to be detected by various sonar devices. It is a pity for Yan Fei that drones cannot be invisible on the seabed, but other aspects of drones

The strength of the face concealed this regret.

After Yan Fei tested the data of level 4 drones, he had a better understanding of drones in his heart, which helped him to accurately display the combat effectiveness of drones. After the test, the drone rose to the surface of the sea, began to turn, and returned to the vicinity of downtown Tokyo. The drone flew close to the ground, carefully avoiding the military radars of the island countries and the Mi Army. It was late at night, and no one noticed this huge monster flying close to the ground.

The drone returned very smoothly to the mine where Yan Fei sorted out the general space items before, and hovered at the entrance of the mine. Yan Fei jumped off the drone and entered the mine, and found that some of the codes he had made were intact. It doesn't move, which means that no outsiders have come in during this time. So he entered the mine and collected the items hidden in the mine into the general space.

The general space volume of the upgraded drone has reached 1,000 cubic meters, and the storage space has increased by a full 10 times. After he put those things back into the general space, he found that all the items only occupied a small part of the general space. Having such a large space will greatly facilitate his future actions and give him more choices.

After collecting the things, Yan Fei checked it carefully again, and erased all the traces left in the cave. Originally, he wanted to set fire to this place and completely destroy all traces, but the gasoline stored in the general space has been used up. He also considered using explosives to blow up the cave, but the movement would be too loud, and it would easily attract the attention of the island country, so he had no choice but to give up.

After cleaning up the clues that he may have left traces in the island country, Yan Fei returned to the drone, then started the drone, began to fly close to the ground, and returned to the sea. This time when he came to the island country, Yan Fei overfulfilled his mission, but due to various accidents and emergencies, he stayed in the island country for more than a week. In order to keep it secret, he has not been in contact with Lu Pingping in China during this period of time, and he does not know how far the situation of the domestic company has developed. He misses the domestic company and friends a little.

So after Yan Fei completed the task, he decided to return to Huaxia immediately. Originally, it was the safest choice to let the drone sneak under the sea and slowly return to Huaxia. However, Yan Fei disliked that the speed of the drone's sneaking on the seabed was too slow, so he let the drone fly across the sea at a low altitude and quickly moved towards Huaxia.

The drone was flying across the sea towards the west, and Yan Fei suddenly thought of one thing, that is, the USB flash drive he had been entrusted by the Chinese female agent before. At that time, the female agent also said that if she did not come to Yan Fei three days later, she would ask Yan Fei to send the USB drive to a warehouse in Tokyo Port, and Yan Fei also agreed at that time.

Yan Fei is going back to China now, so the female agent must not be able to find herself in the island country, and he will not go to the warehouse in Tokyo Port, because this is an island country, even if the drone is upgraded to level 4, it is still very dangerous. So he planned to bring the USB drive back to the country, and then hand over the USB drive to the country through other channels, which can be regarded as fulfilling the female agent's entrustment in disguise.

With this decision, the drone continued to fly towards the west, but after the drone flew for a period of time, Yan Fei suddenly thought of a possibility, that is, he had decided not to go to that warehouse, but it was difficult to protect those domestic workers. The agents were waiting there. After all, the data in this USB flash drive was very precious. They had to take it back to complete the task assigned by the country.

If those agents hadn't waited for Yan Fei in that warehouse, would they have thought that Yan Fei had an accident, and then carried out operations in the island country again and retrieved the USB drive. At this time, the island countries have already tensed their nerves because of their own reasons. Will they throw themselves into the trap for this reason and cause heavy losses?

Thinking of this, Yan Fei was a little embarrassed. He would not go to the warehouse to meet those Chinese agents again, but at least he could warn them and let them leave there, so as not to be discovered by the islanders and cause heavy losses. For these people who are willing to do this for the country For those who sacrificed, he still maintains enough respect in his heart.

So under the control of Yan Fei, the drone began to turn around on the sea and flew in the direction of Tokyo Bay.

The drone was flying fast, and soon flew into Tokyo Bay. As soon as it enters Tokyo Bay, the drone dives to the bottom of the sea, sneaks on the bottom of the sea, and moves quickly towards the direction of Tokyo Port. This is Tokyo Bay, one of the densest waterways in the world, even if the drone is flying at low altitude over the sea

If it does, it will also be spotted by other ships, thus revealing its tracks.

Soon, the drone came to the port of Tokyo. It was hidden on the seabed, and the quantum radar was started to scan the vicinity completely. Unexpectedly, it was discovered that the Tokyo Port warehouse was brightly lit, and a large number of heavily armed rice and Japanese soldiers were surrounding a large warehouse. There are more than a dozen Mi Army m1a2 main battle tanks parked on the flat ground in front of the warehouse, several Apache helicopter gunships hovering in the sky, and several fighter jets overhead.
