Chapter 1186: Chapter 469: Mysterious Aircraft Chapter 1186: Chapter 469: Mysterious Aircraft The metal doors of the underground warehouse were only opened from the outside after Yan Fei piloted the Drone Avatar up to fifty meters above the underground warehouse. A group of American soldiers fully clad and decked out in gas masks came storming in from the outside.

But by this time, there was no sign of the invader inside the disheveled warehouse. Glass shards littered the ground, and the stone holes in the rock walls were empty–the prized remains of the mysterious aircraft had vanished. A massive hole had appeared in the ceiling and wall above, leading into the dark unknown and occasionally dropping mud and sand…

In the center of the warehouse lay a neatly stacked pile of explosives that looked to weigh several dozen tons. Directly above the explosives was a small, trigger-activated timing device, which was still flashing a red light. As the device sensed a large number of personnel entering, the light flashed more urgently.

The commander of the group of American soldiers realized something was wrong and bellowed, “It's a trap, retreat immediately, retreat immediately…”

Unfortunately, the commander's order was too late. The soldiers had no chance to evacuate before the timer's red light suddenly turned green, and the massive pile of explosives detonated in a ground-shaking explosion. Shock waves and flames engulfed the entire underground warehouse, swallowing the team of American soldiers and then rushing out towards Area 51 through the metal doors, destroying everything in their path…

Even the Drone Avatar, which Yan Fei had used for underground traversal and left behind the vertical tunnel, was hit hard by the shock waves and flames surging upward. However, the Drone Avatar was extremely sturdy, especially in Subterranean Mode, almost indestructible, so this level of attack wasn't enough to damage it. Yet, the upward force did increase its speed as it ascended.

The tough rock of the underground tunnel eroded into loose sand by the Drone, perfectly suited for the vehicle to ascend in reverse direction. In just two minutes, the Drone had traveled from 200 meters below ground to the bottom of the Great Gorge at a depth of 100 meters.

Upon reaching the bottom of the gorge, the Drone climbed back up in the same direction it had descended. Driven by two powerful tracks underneath, the Drone Avatar quickly resurfaced. Yan Fei switched the Drone's mode from underground burrowing to standard flight mode and saw it quickly transform back into the B-2 shape.

Then the Drone levitated, ascending to an altitude of 500 meters. Only then did Yan Fei feel completely at ease because no one could harm him anymore. Although the previous underground traversal mode was powerful, it was very inflexible and slow, leaving it vulnerable to enemy attacks. If someone had discovered the burrowing Drone and attacked it continuously with powerful bombs, it would have been destroyed due to its inability to evade. Only by returning to the skies did Yan Fei regain a sense of safety.

Then the Drone “saw” three armed helicopters flying over from the core area of Area 51, and below them was a procession of US military vehicles shining with bright white lights. Judging from their direction, they seemed to be heading towards the Great Gorge where Yan Fei had been earlier.

Yan Fei understood that the Area 51 defense forces, unable to enter the underground warehouse in time, had dispatched ground and aerial troops to check the surface above the Underground Storage Warehouse, to investigate how the enemy had infiltrated from the surface to the underground, and to block the retreat routes of the invaders on the surface, attempting to catch everything in one go.

At that moment, an explosion suddenly occurred in a different part of Area 51, followed by a collapse of the ground and a massive flame shooting up from the hole, reaching high into the sky with impressive force. It turned out that the explosion in the underground warehouse had finally triggered a chain reaction, resulting in a major explosion in a part of Area 51. The explosion was so powerful that it caused the entire area to collapse, indicating that the fifty tons of explosives Yan Fei had used earlier had done considerable damage to Area 51.

Although Yan Fei had successfully escaped from the underground warehouse, he had left behind the unmistakable tunnel bored by the Drone. Not wanting the Americans to learn about the Drone's underground parameters, Yan Fei decided to destroy this obvious evidence completely. The Drone's external space channel opened, and three massive Super Bombs, each weighing over ten tons, emerged and dropped towards the bottom of the Great Gorge.

These bombs landed precisely at the bottom of the gorge and exploded violently, completely destroying the Drone's burrowed tunnel and causing the valley above the gorge to collapse. Thousands upon thousands of tons of mud and sand cascaded down, effectively sealing off that section of the Great Gorge. This way, no one would be able to collect traces left by the Drone, and its secrets would remain hidden.

The distant US Forces, noticing the explosion near the Great Gorge, came to an abrupt halt. The soldiers disembarked from the vehicles, skillfully readying themselves for combat. The armed helicopters in the sky also halted their advance, drawing closer to each other to form a small combat formation.
