Super Invincible Battleship

Under the control of Yan Fei, the drone flew quickly, increasing its speed to the limit of 2.5 times the speed of sound. In just 20 minutes, the clone of the drone came from Santa Fe to the 50th place in the hinterland of the western desert. a district.

Area 51 is the most mysterious area in the United States, and the protection of Area 51 by Americans is also very strict. There are many air defense radars and air defense weapons hidden in the open and in the dark, and there is even a garrison army. However, the UAV is completely invisible to radar. Even if it flies over the 51st area swaggeringly, it is impossible to be detected by the 51st area's air defense system.

Area 51 is very large, more than ten kilometers long from south to north, and most of its buildings are built underground. The great rift valley where Yan Fei escaped from the pursuit of the Mi Army was located in the northernmost remote area of ​​the 51st District. The reason why Fei was not attacked by the 51st District defense force.

Later, Yan Fei used the artificial intelligence "Dream" to search for information on the 51st District on the Internet, and got the structure map of the underground buildings in the 51st District, but he knew the distribution of the underground buildings in the 51st District . He compared it with the location of the necessary items for upgrading that he sensed before, and found that the necessary items for upgrading that he sensed should be located in the storage warehouse in District 51.

The storage warehouse was 200 meters deep from the ground. Yan Fei was at the bottom of the Great Rift Valley at the time, and the depth of the valley bottom exceeded 100 meters. Yan Fei was actually only 100 meters away from the underground storage warehouse, so no one was there. The machine will find the necessary items for upgrading in the storage warehouse. Yan Fei hadn't seen this upgrade item with his own eyes, so he didn't know what it was. But as long as he enters the storage warehouse in person, he can immediately know what the upgrade must be.

Yan Fei's action plan this time is to enter this underground storage warehouse, and then take away the necessary items for upgrading from the warehouse.

The drone quietly came over the Great Rift Valley in the hinterland of the desert, and hovered in the air according to Yan Fei's previous memory. The drone did not make any sound during its flight, and it has the functions of radar stealth and optical camouflage. In addition, it is late at night, the sky is dark, and the 51st district not far away is in a state of blackout, so who It was also not discovered that this drone, which caused great harm to the United States, had arrived in Area 51.

Yan Fei controlled the drone to hover in the air. This altitude was more than 200 meters above the ground, and the drone did not sense the necessary items for upgrading underground. Yan Fei hesitated for a moment, but still opened the cockpit door, and then the drone turned over, turned head down, Yan Fei jumped out of the cockpit, and quickly fell towards the ground.

Yan Fei is a god-level master, so powerful that he can jump directly from a height of 300 meters without even needing a deceleration device. The fact is also the same, Yan Fei fell steadily into the Great Rift Valley, but his feet were inserted into the sand and gravel due to the huge impact, but his body was not injured in any way.

Yan Fei stood where he was,

After identifying the direction, he began to run towards the direction in his memory. Soon, Yan Fei came to the bottom of the Great Rift Valley where the mark was left before. As soon as he came here, the auxiliary brain sent a message, reminding Yan Fei that he found items necessary for drone upgrades within a 100-meter radius.

After seeing this piece of information, Yan Fei was completely relieved, because the items necessary for the upgrade still exist, he did not leave here, and he did not come late. Then the drone in the sky activated the quantum radar to scan the underground conditions near the Great Rift Valley. Soon, all the nearby terrain conditions appeared in Yan Fei's mind, allowing Yan Fei to know the situation here like the palm of his hand.

In the quantum radar scan, Yan Fei found that there were many huge buildings at a depth of 100 meters underground. These buildings stretched for several kilometers, and there were various research equipment inside, and many scientific researchers were working. Obviously, these buildings are the underground research center of Area 51.

However, from the information Yan Fei had obtained before, he knew that the core building complex in District 51 should be located at a depth of 200 meters underground, and these buildings at a depth of 100 meters were only the primary research center of District 51. It's a pity that Yan Fei doesn't know what's in the ground two hundred meters away.

The UAV quantum radar is very powerful, but when scanning the ground, it has a big shortcoming, that is, its scanning depth is insufficient, only a mere 100 meters. Once the depth exceeds one hundred meters, the quantum radar cannot know the specific situation. However, the bottom of the Great Rift Valley where Yan Fei is located was originally 100 meters deep, and the quantum radar can still scan the bottom of the Great Rift Valley 100 meters further down.

At a depth of 100 meters below the bottom of the valley where Yan Fei was most suspicious, the quantum radar scanned the outline of a huge storage warehouse. It's just that the bottom of the Great Rift Valley where Yan Fei is standing is very narrow, and the space that the quantum radar can scan through this narrow valley bottom is not very large. So although Yan Fei found out that there is really a storage warehouse underground, he doesn't know the specific situation of this storage warehouse.

After seeing this storage warehouse, Yan Fei was relieved. This shows that his previous speculation was correct, and the items necessary for drone upgrades are in this underground storage warehouse. He is located exactly 100 meters away from this storage warehouse, so he can sense the items in the storage warehouse. From the information collected by "Fantasy", it can be seen that this storage warehouse is very important to the 51st district, so it is built in the strongest place in the 51st district, and can only be accessed through the passage of the 51st district. .

Under the scanning of the quantum radar, Yan Fei clearly found that the storage warehouse is full of hard rock layers, and it is impossible for outsiders to enter the underground storage warehouse through these hard rock layers. The reason for building a security building on the ground above the warehouse. In their view, no one can enter this underground storage warehouse in other ways except for the built passage, so there is no need for special defense of this storage warehouse.

After confirming the destination of the trip, Yan Fei immediately controlled the drone to land in the Great Rift Valley. The bottom of the Great Rift Valley is very narrow and cannot accommodate the huge fuselage of the drone. As soon as the drone landed in the Great Rift Valley, Yan Fei switched the drone to the underground stealth mode.

I saw that the drone began to deform rapidly. A huge sharp drill appeared at the front, and two huge crawlers appeared under the body. Under the control of Yan Fei, the huge drill bit at the front of the drone started to rotate, cutting off the rocks and soil blocking the road like tofu. Then the two crawlers under the body quickly transmitted, pushing the huge drone to crawl towards the bottom of the Great Rift Valley.

The drone is now facing the softest rocks and soil, and there is a huge downward space, so it dives very fast. In just a few minutes, it drilled vertically to the depth where Yan Fei was. . Yan Fei opened the cockpit of the drone, jumped into the cockpit, then closed the hatch, and drilled towards the storage warehouse below.

The drone's submersion mode is very powerful, it regards rocks and soil as tofu, and can easily drill through them. But the strange thing is that the drone makes very little sound during the whole process. If it is not relying on special instruments, it is impossible to detect the sound of the ground, and naturally the trace of the drone will not be found.

From the bottom of the Great Rift Valley, drones enter true subterranean stealth mode. From Yan Fei's subjective perspective, he saw darkness outside the transparent cockpit. If it wasn't for the slight shaking of the drone body, he even thought that the drone wasn't heading underground.

Fortunately, after the drone entered stealth mode, a map of the underground structure within a radius of 20 meters appeared on the front dashboard. On this underground structure map, Yan Fei can see the sneak direction and speed of the drone. It is with this dashboard that Yan Fei knows what the stealth situation of the drone is like.

At the very beginning, the drone's underground sneak speed was still very fast. Because it is full of soft soil and rocks, it can advance more than ten meters in a minute, leaving only a soft vertical downward passage behind. But when it was only 50 meters away from the underground storage warehouse, the drone encountered the hard rock layer, and then its forward speed slowed down significantly, only one meter per minute.

After entering the real underground stealth, the energy point consumption of the drone has also increased significantly. The drone has sneaked a distance of 50 meters underground, and it has consumed as many as 500,000 energy points. After the data of the drone is refreshed every day, there are 10 million energy points. These energy points can only support the drone to sneak up to 1,000 meters underground.

This is still the case of soft rock and sand. If it encounters a hard rock layer, the drone will consume more energy points. Moreover, as long as the drone clone stays underground, it will encounter tremendous pressure from all directions. In order to ensure that it will not be crushed by these pressures, the drone must also consume a certain amount of energy points to resist these pressures from the ground. So if it wasn't for special circumstances, Yan Fei would never activate the drone's underground stealth function at all.

Yan Fei is still 50 meters away from the underground storage warehouse. With his current sneak speed, it will take at least 50 minutes to enter the storage warehouse. However, Yan Fei's purpose of this operation is clear, that is, to obtain the necessary items for upgrading the drone, and he can afford to delay this time.

As long as the drone enters a depth of 100 meters underground, the connection to the outside network will be intermittent. After it entered the ground for 150 meters, all connections with the outside network were cut off. In this way, Yan Fei would not be able to keep abreast of the situation outside, and would not be able to respond accordingly to these situations. Therefore, before entering the underground, Yan Fei authorized the artificial intelligence "Dream". Once an unexpected situation occurs during the time when Yan Fei cannot connect to the network, "Dream" can respond accordingly to the unexpected situation.

At the very beginning, "Fantasy" was invaded and attacked by an unknown artificial intelligence. It was caught off guard by its opponents, so it could only respond passively and could not do other things separately. But "Dream" is much stronger than that artificial intelligence in essence, and after this failure experience, its growth rate is even more amazing.

Although "Fantasy" and the artificial intelligence are still in a state of entanglement with each other, the battle situation has changed from being evenly matched before to now gaining the upper hand. Although "Fantasy" is still unable to repel the incoming artificial intelligence, more computing power has been liberated and it can focus on other things. At this time, Yan Fei handed over the supervision rights of the outside world to "Fantasy", which was just right.

The rock layers encountered by the drone are very hard. These rocks are not as hard as the steel rocks on Neverland, but the hardness is also rare. The Americans discovered this rock layer before, so they forcibly dug out a storage warehouse in this rock layer to store the most valuable items, and did not worry about anyone entering the storage warehouse from the outside.

When the Americans built this storage warehouse, they had no idea that there was a freak drone clone in the world, which could actually sneak in the hard rock layer. The underground sneak speed of the drone is very slow, but it is constantly approaching the storage warehouse.

In the absolutely dark underground, Yan Fei spent the most difficult fifty minutes. During these 50 minutes, the drone drilled a huge 50-meter tunnel, abruptly descending from the ground to a depth of 200 meters. On the dashboard, Yan Fei knew clearly that the wall of the storage warehouse was 50 centimeters ahead. He only needed to keep going, and he would be able to enter the storage warehouse in 30 seconds.

However, Yan Fei was not in a hurry to enter the storage warehouse. He activated the quantum radar again and scanned the ground in a large area. It is completely different from the scanning distance of thousands of kilometers in the sky. Under the ground, the scanning distance of quantum radar is only 100 meters, which is pitifully small. However, even if it can only scan a distance of 100 meters, it is enough for Yan Fei to know the surrounding situation like the palm of his hand.

In the ground below is the huge storage warehouse. This storage warehouse has a very large area and a height of more than 20 meters. There are many strange items that Yan Fei has never seen in the storage warehouse. The storage warehouse has only one huge exit, connected by a solid metal gate to the rock corridor outside.

In the quantum radar scan, Yan Fei clearly saw all kinds of powerful weapons hidden in the rocky corridor outside. Anyone who ventured into this rocky corridor without authorization was instantly killed by the weapons within and there was no escape.

There is also a huge research room outside the corridor. This room is full of various instruments, but more items are daily necessities. It is like an inhabited bedroom, but at this time the room is empty. one person.

With the help of quantum radar, Yan Fei found two photos on the table in this room, which used the latest concave-convex imaging technology. So although Yan Fei himself cannot see these two photos, he can "see" the contents of the photos with the help of quantum radar, but he cannot see the specific colors.

Then Yan Fei found out that he actually knew the person in one of the photos, because the person in this photo was actually the god-level master who had undergone body mutation—the beast. The beast in the photo doesn't look too far away from the real beast, so his expression is melancholy and he looks very depressed.

The photo next to it was a group photo of a young man and a beautiful woman. Although Yan Fei couldn't see the "color", he felt that the young man should be a white man. In the photo, the young white man put his arms around the beautiful woman, with a big smile on his face, and the two seemed to be in a relationship.

This young man is somewhat similar to the mutated beast. He should be the original face of the beast before it mutated. The unmutated beast has a beautiful girlfriend, but the mutated beast has a scary appearance, and there are no female items in the room, which means that the beast has been abandoned by the beautiful girlfriend, so the later photos will look so melancholy.

Combining the various instruments in the room and the contents of the photos, Yan Fei immediately determined that this room should be lived by the beast alone. The beast here is not only cooperating with medical experts to conduct various inspections on its body mutation, but also protecting the safety of this underground storage warehouse.

The Beast had already gone to the Submarine Square to perform a mission, but was seriously injured by Gu Xiaolan in the small space behind the Light Gate, and nearly died. After escaping and ascending to the sky, he was chased by the super giant transformed by Sun Tie, and finally escaped to the Bush aircraft carrier, and then was violently attacked by Yan Fei's drone. He probably died a long time ago, and the beast should not be able to return to this room. up.

At this time, Yan Fei suddenly realized that when he wanted to snatch the items necessary for upgrading, he found that there was a huge danger hidden here. He didn't know the reason before, but now he discovered that the second god-level master of the United States was hidden here, that is, the beast. If he forcibly came to Area 51 to snatch items and didn't realize that there was another god-level expert here, once he was intercepted by wild beasts underground, it would be really bad luck...

But now that Yan Fei is powerful, and the beast may have been killed by him, he is naturally not afraid that someone here will hurt him. It's a pity that the farthest scanning distance of the drone in the ground is only 100 meters, and the beast's room is already the furthest away from 100 meters, so Yan Fei can't know more information about Area 51, and naturally he can't Know what the people in Area 51 are researching.

However, probing the secrets of Area 51 is not the theme of Yan Fei's operation this time, he just wants to obtain the necessary items for upgrading. Knowing the specific situation here, under the control of Yan Fei, the drone continued to sneak down. Thirty seconds later, the drill bit of the drone clone was empty, and finally penetrated the hard wall of the storage warehouse.

At the same time that the wall of the storage warehouse was destroyed by the drill bit, the alarm in the storage warehouse was triggered, and the shrill siren sounded suddenly, echoing everywhere in Area 51...
