Chapter 1253: Chapter 495 Underground Traversal Chapter 1253: Chapter 495 Underground Traversal In the pitch-black night sky, thanks to complete radar stealth ability combined with negligible noise, nobody noticed the drone flying at 25,000 meters altitude. It was traveling at 2.5 times the speed of sound, and in just three short hours, it had crossed the airspace of five countries, flying from the distant North Pacific to the Persian Gulf waters in the Middle East.

The drone had taken off at 8:30 PM local time on Dream Island; by the time it had been flying for three hours and arrived in the Gulf Region near Kuwait, it was already 11:30 PM on Dream Island, yet only 6:30 PM in Kuwait. The sky there hadn't even completely darkened, it could be said that Yan Fei had entirely kept pace with the passage of time…

High above the Persian Gulf waters, far from Kuwait port, the drone's quantum radar rapidly scanned the area. After detecting no threats, it quickly descended and plunged straight into the sea. In the water, the drone transformed into the most suitable shape for underground traversal, advancing swiftly beneath the seabed of the Persian Gulf. Its course was directly toward the underground of Kuwait City, where the Auxiliary Brain had deduced the most likely existence of a huge underground space.

Twenty minutes later, the drone approached Kuwait terrestrial land from the seabed at high speed. At this moment, because the drone had descended to the ground and came into contact with Kuwait's seawater, its data refresh location changed from Dream Island to Kuwait; its next data refresh was scheduled for midnight in Kuwait, nearly six hours away. Therefore, when the time on Dream Island reached midnight, the drone's data hadn't refreshed. However, following the long flight's consumption, the drone now had only half its energy points left, not even five million points.

After approaching the land from the seabed near Kuwait, the drone didn't immediately go ashore; instead, it activated its subterranean mode, changing into a shape suitable for underground traversal and began burrowing directly under the seabed. Upon entering the underground burrowing mode, from Yan Fei's subjective viewpoint, he saw nothing but darkness outside the transparent cockpit. Had it not been for the slight vibration of the drone body, he might have thought the drone wasn't moving forward at all.

Fortunately, after the drone started its underground operation, a display appeared on the dashboard, showing an underground structure map within a 20-meter radius. On this underground structure map, Yan Fei could see the drone's direction and speed of traversal. It was with this dashboard that Yan Fei could control the situation of the drone's underground travel, and manage everything effectively.

The drone first burrowed toward the direction of the land; after completely leaving the ocean, it made a turn to advance toward higher grounds of Kuwait's territory, preventing the seawater from following and entering along the pathway. Only after completely stopping the inflow of seawater did the drone change direction again, burrowing vertically toward the underground.

At the beginning, the drone's underground burrowing speed was quite fast. The area was a desert region with mostly loose sand and very few rocks underground. As long as it avoided those rocks, the drone could advance more than 10 meters per minute, leaving behind a very loose tunnel. Directly below the drone was the speculated huge underground space, with massive Kuwait City above it.

Once the forward direction was confirmed, the drone started to burrow vertically into the ground at high speed. The underground of Kuwait still primarily consisted of a great amount of mud and a few rocks, so the difficulty of underground traversal wasn't very high. Once the drone had burrowed 300 meters into the ground, viscous black oil began appearing amidst the surrounding mud and rocks.

Yan Fei initially thought that underground oil existed in the form of oil lakes or oil oceans. Only when he came face to face with it did he realize that the reality of underground oil was beyond his expectations.

It turned out that underground oil existed in liquid form within the pores of the underground mud and rocks; some were also found in fractures or caves formed underground, where the oil could manifest as oil oceans or lakes. But most of the oil resided within the rock and sand pores. Just like the beach near the sea, you can't see the sea water on the beach, but if you stomp hard on the beach sand, water will emerge through the gaps in the sand.

Originally, underground traversal by the drone was extremely difficult, consuming a lot of energy points and progressing slowly. But since entering the oil layer, due to the lubricating effects of the oil, the resistance during the drone's traverse significantly decreased, not only making the drone's speed much faster, reaching 20 meters per minute, but also the consumption of energy points dramatically reduced to half.

With the remaining five million energy points, the drone could theoretically only support underground traversal for 500 meters. However, thanks to the substantial lubrication from the massive oil layer, the drone significantly reduced its consumption and burrowed 1000 meters downward in just over an hour. By this time, the drone's energy points were almost exhausted.

For safety, Yan Fei stopped the drone's further traversal and chose to remain stationary. The remaining energy points would be used to resist the immense pressures from all directions underground, ensuring he wasn't crushed by these forces.

While waiting for the drone data refresh, Yan Fei sat in the drone cockpit, looking at the black oil sticking to the cockpit glass, feeling amazed at how Earth maintained the obtained solar energy in such a way; yet humans still had to rely on this fossil energy, supporting human society's entry into the industrial age. From now on, however, Yan Fei was set on destroying this fossil resource on Earth, thoroughly dismantling the US dollar hegemony of The United States of America…
