Chapter 1181: Chapter 467: Underground Warehouse_2 Chapter 1181: Chapter 467: Underground Warehouse_2 Under the scan of the Quantum Radar, Yan Fei clearly discovered that the Storage Warehouse was entirely surrounded by hard rock layers, making it impossible for outsiders to enter the Underground Storage Warehouse through these hard layers. This was the reason the United States had not built any alert structures on the surface above the Underground Storage Warehouse. In their view, aside from the constructed passage, no one could enter the warehouse in any other way, so there was no need for special defense measures.

Once the target location had been confirmed, Yan Fei immediately controlled the Drone to descend into the Great Gorge. The base of the Great Gorge was very narrow, incapable of accommodating the massive body of the Drone. As soon as the Drone landed in the Great Gorge, Yan Fei switched it to underground burrowing mode.

The Drone began to rapidly transform, a huge sharp Drill Bit appearing at the front, and two gigantic tracks appeared beneath its body. Under Yan Fei's control, the huge Drill Bit at the front started to spin, cutting through rocks and soil like tofu. Then, the tracks below swiftly moved, pushing the massive body of the Drone as it crawled towards the bottom of the Great Gorge.

Now facing the softest rocks and soil, and with a vast space downward already present, the Drone's burrowing speed was extremely fast. In just a few minutes, it had drilled vertically down to the depth where Yan Fei was located. Yan Fei opened the Drone Cockpit, jumped in, and then closed the door, drilling downwards towards the Storage Warehouse.

The Drone's Subterranean Mode was incredibly effective, treating rocks and soil as if they were tofu, easily drilling through them. However, what was odd was the extremely low noise produced by the Drone during the entire process. If it weren't for specialized equipment, it would have been impossible to detect any underground movements, and naturally, the Drone's presence would have gone unnoticed.

Starting from the base of the Great Gorge, the Drone entered into true underground burrowing mode. From Yan Fei's perspective, he saw darkness outside the transparent Cockpit; had it not been for the slight tremor of the Drone Body, he might have thought the Drone was not moving underground at all.

Fortunately, once in burrowing mode, the instrument panel in front displayed an Underground Structure Map within a twenty-meter radius. On this map, Yan Fei could see the direction and speed of the Drone's burrowing. It was this instrument panel that informed Yan Fei of the Drone's burrowing conditions.

Initially, the burrowing speed of the Drone was quite fast. Since it was all soft soil and rocks, it advanced over ten meters per minute, leaving behind a soft vertical tunnel. However, when it was only fifty meters away from the Underground Storage Warehouse, the Drone encountered the hard rock layer, and its speed drastically slowed to one meter per minute.

Upon entering real underground burrowing mode, the Drone's Energy Points consumption significantly increased. The Drone covered fifty meters underground, consuming fifty thousand Energy Points. With a daily data refresh of ten million Energy Points, these points could only support the Drone burrowing a thousand meters.

This was under the conditions of encountering soft rocks and sand. If it encountered hard rock layers, the Drone would consume even more Energy Points. Additionally, the Drone Avatar had to face immense pressure from all sides while staying underground. To ensure it wasn't crushed by this pressure, the Drone had to consume certain Energy Points to counteract this underground pressure. Hence, unless there were special circumstances, Yan Fei would not activate the Drone's underground burrowing function.

Yan Fei was now fifty meters away from the Underground Storage Warehouse. With his current burrowing speed, it would take at least fifty minutes to enter the warehouse. However, Yan Fei's purpose this time was clear: he wanted to acquire Upgrade Essential Items, and he could afford this amount of time.

Once the Drone went one hundred meters deep underground, its connection with the Internet started to be intermittent. When it reached one hundred and fifty meters underground, its connection with the Internet was completely interrupted. This made it impossible for Yan Fei to immediately understand the situation outside and respond accordingly. Therefore, before going underground, Yan Fei authorized the Artificial Intelligence “Dream” to take action in case of any unforeseen circumstances during the period Yan Fei could not connect to the Internet.

At first, “Dream” was caught off guard by an unknown Artificial Intelligence Invasion and could only react defensively, unable to take any other actions. However, “Dream” was fundamentally much more powerful than that Artificial Intelligence, and with the experience from this failure, its growth rate was astonishingly fast.
