Chapter 474 Subterranean Sneaking
In the dark night sky, because of the complete radar invisibility and the negligible noise, no one could detect the drone flying at an altitude of 25000 meters.It was flying at a speed of 2.5 times the speed of sound. In just 3 hours, it crossed the airspace of five countries and flew from the remote North Pacific to the Persian Gulf in the Middle East.

When the drone took off, it was 08:30 p.m. local time in Neverland. When it flew for three hours and came to the bay area where Kvitt is located, it was already 11:30 p.m. :06.The sky outside is not completely dark, it can be said that Yan Fei has completely caught up with the passage of time...

Over the waters of the Persian Gulf far away from the port of Kvit, the UAV quantum radar in the sky quickly scanned, and after finding no danger, it quickly descended and dived directly into the sea.In seawater, the UAV becomes the most suitable shape for submarine diving, and travels at high speed on the bottom of the Persian Gulf.The direction it is going is the underground of Kvit City, which is the most likely location for the huge underground space deduced by the assistant intelligence brain.

10 minutes later, the drone approached the city of Kvett from the seabed at high speed.At this time, because the drone descended to the ground and touched the sea water of Kvet, its data refresh location has changed from Neverland to Kvet, and its next data refresh will be at 12 o'clock in the morning of Kvet time , there are still nearly 6 hours from now.So when Neverland time has come to 12 o'clock in the morning, the drone's data has not been refreshed.However, under the consumption of long-distance flight, the current energy point of the drone is only half, less than 500 million points.

After approaching the land of Kvitt from the bottom of the sea, the drone did not go ashore immediately, but activated the submerged mode, changing itself into a shape suitable for subsurface sneaking, and started submerging directly on the bottom of the sea.After entering the underground 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 was not heading underground.

Fortunately, after the drone entered the underground 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 can control the stealth of the drone and control the overall situation.

The drone first digs towards the land, and when it leaves the ocean completely, it turns a corner and heads towards the high land of Kvitt, preventing the seawater below from flowing in along the forward passage.After completely cutting off the entry of seawater, the drone changed direction again and dived vertically below the ground.

At the beginning, the drone's underground sneak speed was still very fast.Because this is a desert area, the ground is full of soft sand, and only a few rocks exist.As long as it bypasses that part of the rock, the drone can advance more than 1 meters in one minute, and the drone sneaks past and leaves a very soft sneak channel behind it.Below the drone is the deduced possible huge underground space, and above it is the huge city of Kvit.

After determining the direction of advancement, the UAV will quickly dig into the ground in a completely vertical direction.At this time, the underground of Kvitt is still dominated by a large amount of sand and a small amount of rocks, so it is not very difficult for drones to sneak underground.After the drone dived 300 meters underground, viscous black oil began to appear in the surrounding sand and rocks.

Yan Fei originally thought that the underground oil existed in the form of oil lakes or oceans, but when he was there, he discovered that the underground oil existed in a way beyond his expectations.

It turns out that underground oil exists in liquid form in the pores of underground sand and rocks, and some of it exists in cracks or caves formed underground. That part of oil exists in oil lakes or oil oceans.But most of the oil exists in the pores of sandy rocks.Just like the beach near the sea, you can't see the sea water on the beach, but step hard on the beach a few times, and the sea water will emerge from the gaps in the sand on the beach.

Originally, the drone's sneaking underground was very difficult, requiring a lot of energy points, and the speed was very slow.However, since entering the oil layer, due to the lubricating effect of oil, the resistance of the UAV during sneaking has been greatly reduced. Not only has the UAV's sneaking speed become faster, reaching 1 meters per minute, but the consumption of energy points has also been greatly reduced. Reduced, only half of the previous one.

With the remaining 500 million energy points of the drone, it can only support the drone to sneak up to 500 meters underground.However, under the lubricating effect of a large amount of oil in the oil layer, the stealth consumption of the drone was greatly reduced, and it only sneaked down a full 1000 meters in just over an hour.By this time, the energy points of the drone are almost exhausted.

For the sake of safety, Yan Fei stopped the drone from continuing to sneak, and chose to stay where he was.Those remaining energy points will be used to resist the huge pressure from all directions underground, so as to ensure that you will not be crushed by these pressures.

While waiting for the UAV data to be refreshed, Yan Fei sat in the UAV cockpit like this. Looking at the black oil stained on the cockpit glass, he felt that the earth was very magical, and it was actually maintained in this way. However, human beings have to rely on this kind of fossil energy to support human society to enter the industrial society.But from now on, Yan Fei will destroy this fossil material on the earth to completely defeat the U.S. dollar hegemony...

The 1000-meter-deep underground was terribly silent, and it was pitch-black everywhere. The only thing Yan Fei could see was the underground structure with a radius of 20 meters.Because of the obstruction of underground rocks and soil, the longest scanning distance of the quantum radar of the UAV is only a pitiful 100 meters, so Yan Fei will not activate the quantum radar at all, because it is just a waste of energy points.

If it was someone else, if he stayed in this dark and quiet environment for a long time, his spirit might have problems, and he might even go crazy.But Yan Fei is different. He is a god-level master. Not only has he reached the pinnacle of body control, but his mental power is also extremely powerful, which can ensure that his spirit is always within the normal fluctuation range.Moreover, Yan Fei still has hatred in his heart, he wants to avenge Wen Rou, this obsession supports him to persevere.In order to accomplish this goal, even if he stays in this extreme environment forever, he will have no regrets...

Four hours later, at 4 o'clock in the morning local time in Kvitt, the data of the drone began to be refreshed. The body of the drone vibrated slightly, and all the data returned to full value, even the energy points also returned to the peak period of 12 million. point.

With enough energy points, Yan Fei continued to control the drone to sneak under the ground.Under the guidance of the arrow in Yan Fei's mind to assist the intelligent brain, the direction of the drone's dive strictly follows the guidance without any deviation.This direction is obtained by the auxiliary brain after rigorous reasoning. If there is really a huge space underground, then it must be in the direction guided by the auxiliary brain.

From the depth of 1000 meters underground, the oil outside the drone window increased a lot, the sand in the ground decreased rapidly, and the number of rocks of different sizes began to increase.Changes in the terrain, especially the increase in rocks, made the drone's dive speed slower.However, even if the difficulty of diving has increased, the drone's stealth speed has not slowed down much under the action of petroleum lubricants.

Three hours later, when the drone stopped due to lack of energy points, it had already dived down 1200 meters again.Without the support of enough energy points, the drone can only lurk in the ground, waiting for the data of the drone to be refreshed again. At this time, the drone is already 2200 meters away from the city of Kvitt on the ground.

Before Yan Fei plans to implement this super plan, he has done a lot of preparatory work.In particular, the logistics support work is very meticulous. He has stored a large amount of living materials in the general space, including hot meals.So even though he has been staying deep in the ground, as long as he wants, he can eat delicious meals immediately, even fresh fruit and tea.

So while waiting for the drone's energy point data to refresh, Yan Fei would think about how to develop Neverland's strength, how to defeat the United States, and how to get rid of the black hand behind the scenes after eating and drinking enough.It was because of Yan Fei's constant thinking that his heart became stronger and he was able to survive this almost crushing underground stealth career.And this place is far away from the outside world, even the black hand behind the scenes cannot affect Yan Fei, Yan Fei feels that only here can he think of real countermeasures...

On the third day, when the drone data had just been refreshed, Yan Fei controlled the drone to continue sneaking underground. The ground at 2200 meters has changed a lot. The sand here has become less and less. On the contrary, there are more and more rocks, and the size is getting bigger and harder.But after reaching this depth, more and more oil was found around the drone.Yan Fei even found a small oil lake in a fractured rock formation.

Generally speaking, after reaching this depth, the drone's underground sneak speed becomes slower and slower, and at the same time, the energy points consumed for underground sneaking are also increasing.Fortunately, the drone is equipped with a complete breathing system, otherwise Yan Fei inside would have died due to lack of oxygen.Under such difficult circumstances, the drone only dived to a depth of 800 meters on this day. At this time, the drone was 3000 meters away from the city of Kvitt on the ground.

On the fourth day, the drone continued to sneak after the data was refreshed, and then found that all the sediment in the ground had disappeared, and the outside of the drone was covered with layers of rocks.Fortunately, these rocks are not hard, and a small and medium-sized oil lake is formed from time to time in the crevices of these rocks, so that drones can take advantage of these oil lakes without drilling holes in the rocks.

At this time, the underground environment is complex, and the resistance of drones to sneak downward becomes larger and larger.On this day, the drone only sneaked down 600 meters. At this time, the drone was 3600 meters away from the city of Kvitt on the ground.

On the fifth day, the underground environment changed again, and the drone began to encounter a large number of hard rocks, which slowed down the drone's underground sneaking speed again.However, Yan Fei was not discouraged, but continued to sneak.After drilling through the 100-meter-deep hard rock layer in one breath, a huge oil lake was discovered under the rock layer.

The length of this oil lake is not large, but the depth has reached a terrifying 500 meters.The UAV quantum radar scan found that this oil lake was formed in the gaps between several huge rocks. It was infiltrated by oil from other places, and it happened to form a huge oil lake here.

Yan Fei was overjoyed, and quickly controlled the drone to sneak in the oil lake.When the drone came to the bottom of the 500-meter-deep oil lake, it was discovered that the hardest granite was underneath.Even if the drone's underground sneak speed is very fast, there is no good way to encounter hard granite areas, only to drill bit by bit.Fortunately, every time the drone advances, the oil behind it moves forward, always acting as a lubricant for the drone, which makes the drone's stealth speed a little faster.

On this day, because of the oil lake, the drone dived down to a depth of 900 meters. At this time, the drone reached 4500 meters from the ground in Kuwait City.

After reaching a depth of 4500 meters, Yan Fei still did not discover the huge underground space that might exist.Yan Fei became a little anxious. You must know that he is currently located at a depth of 4500 meters underground, and his activities are very inconvenient. Once something unexpected happens, such as an earthquake or a volcanic eruption, he will not be able to escape at all, and he will die in this place [-]%.Maybe hundreds of millions of years later, the earth's crust will move, and Yan Fei's body will be seen again, and it will become a research sample for the next civilization on the earth...

Although Yan Fei was anxious, he was determined after all. After hesitating for a day, he strengthened his confidence and continued to sneak down to the ground to complete the impossible super plan of destroying the oil in the Middle East.

However, since encountering this granite area, Yan Fei found that the rocks below are getting harder and harder, and the thickness of the granite seems to be very large.By the end of the sixth day, the drone had carved out a depth of 200 meters in the granite.The seventh day passed, and the drone again dug a 200-meter-deep downward channel in the granite.

At this time, the drone has advanced 400 meters in the granite area, but it is completely impossible to see where the end of the granite area is.But fortunately, this piece of granite is not like the steel rock underground of Neverland. It occasionally encounters one or two gaps or caves in the middle, which makes Yan Fei maintain hope for drilling through this granite area.

In the next few days, the drone still maintained a progress of 200 meters every day, but it never drilled through the granite area.At this time, the UAV has advanced to a depth of more than 5000 meters from the surface of Kvit City, but still no large underground space has been found.

Ten days after entering the granite area, that is, the drone advanced 10 meters in the granite area, and the drill bit that had been rotating at high speed in front suddenly disappeared, and all resistance disappeared.Yan Fei was excited, knowing that this meant that he had finally drilled through this damned granite area.

The drone continued to sneak downwards, and suddenly, the drone completely broke away from the granite area, and fell towards the dark space below at a high speed under the action of the earth's gravity.
