But after the drone completed its upgrade, the entire drone system became invincible within the solar system, and all problems were no longer issues. With the drone's immense strength, Yan Fei could easily crush all armed forces on Earth, reversing the situation was a matter of moments. The only thing he needed to consider was how to achieve this grand reversal and avoid the fearsome natural power of the super tsunami.

The drone carrier is now located on the Spirit Divine Star in the Asteroid Belt, a full 370 million kilometers away from Earth. Even if it rushed back at its maximum speed of 10,000 kilometers/second, it would take ten hours and twenty minutes to reach Earth. This speed was multiple times faster than the speed at which Yan Fei previously traveled to the Spirit Divine Star by spaceship, but even so, it couldn't make it in time for the impending World War on Earth, nor the subsequent super tsunami attack, because time was running short.

If the drone carrier utilized its wormhole creation abilities, it could return to Earth's orbit immediately. However, creating a wormhole requires a massive amount of energy, and given that this is the inner solar system, which is filled with planets and meteorites, even a slight oversight could lead to unforeseen situations, potentially even leading to the drone's destruction. Hence, the wormhole creation capability could only be used in the sparse outer solar system and was not viable within the inner solar system. Therefore, Yan Fei abandoned the idea of having the drone carrier travel back to Earth via wormhole and instead opted for it to return at maximum speed.

Faced with several formidable enemies on Earth, Yan Fei's trump card was not the drone carrier currently rushing back, but rather the super fighter jets of the subsystem. With the upgraded super fighter jets' strong combat power, they were more than sufficient to deal with Earth's military forces.

Thus, Yan Fei separated the super fighter jet from the drone carrier through the drone carrier, then attached his consciousness to the super fighter jet, controlling it to enter Dreamland Cave World through the space channel on the Spirit Divine Star. Although the space channel Yan Fei opened on the Spirit Divine Star was large, it could only accommodate the entry of the super fighter jet, but was unable to handle the much larger drone carrier. Therefore, the drone carrier could only rely on its flight to return to Earth.

After Yan Fei entered Dreamland Cave World, he immediately saw the super fighter jet that had already entered Dreamland Cave World. Before, he had only seen this fighter jet on a virtual control screen. Now, seeing this fighter jet with his own eyes, he was instantly captivated by its heroic presence. After admiring it for a while, Yan Fei opened the super fighter jet's cockpit and jumped inside.

The control process of the super fighter jet is very similar to that of a Level 5 drone, so Yan Fei quickly became acquainted with controlling this super fighter jet and felt the immense power of the super fighter jet. Once he was fully familiar, Yan Fei switched the super fighter jet to subterranean mode. The super fighter jet immediately began transforming, taking on the same subterranean shape as the previous Level 5 drone, although its new form was much larger than the Level 5 version.

Under Yan Fei's control, the super fighter jet entered the space channel in subterranean mode, returning to Dream Island on Earth. However, due to its massive size, the drone was no longer able to exit the underground through the same passage frequently used by the Level 5 drone.

But this posed no challenge for Yan Fei. Under his control, the super fighter jet immediately demonstrated what true subterranean capability meant. A large drill bit rotating rapidly at the front of the super fighter jet bored through the underground's hard rocks, and propelled by two massive treads on its underbelly, it advanced swiftly underground. In front of the super fighter jet, the underground's hard steel rocks resembled tofu, posing no obstacle and allowing it to smoothly advance a significant distance as if it were journeying not through the earth, but underwater.

Quickly, the super fighter jet bored a new passage in the Dream Island underground, then emerged from the other direction to the surface of Dream Island. It took the super fighter jet no more than five minutes to drill from the underground to the surface. The same workload would have taken a Level 5 drone at least two days and nights. From this, it's evident how powerful the upgraded drone's capabilities have become.

The place where the super fighter jet appeared was the military base north of Dream Island. Before starting the subterranean drilling, Yan Fei had arranged through the artificial intelligence "Dream" to place the military base under lockdown and clear out all personnel, so no one knew a terrifying beast was emerging from underground.

After appearing on Dream Island's surface, the super fighter jet began transforming from its previous subterranean mode to a streamlined sci-fi appearance. Following this, its cockpit opened, and Yan Fei jumped out and stood on the ground. Then the cockpit closed, and the super fighter jet began to hover slowly into the sky. As it reached twenty meters above the ground, two blue flames shot from the tail of the super fighter jet, and under immense thrust, it began to rapidly ascend into the sky.

Consistent with its predecessor, even as the super fighter jet flew at incredible speeds, exceeding the speed of sound, it emitted no noise. If people on Dream Island weren't constantly watching the sky, they would completely miss the moment the massive fighter jet zipped away into the sky.

With the energy rapidly transmitted from the drone carrier across vast voids, the super fighter jet's speed increased rapidly. In less than ten seconds, its speed reached 10 kilometers/second, enough to leave Earth's atmosphere quickly and enter outer space. After reaching outer space, the super fighter jet's speed didn't diminish but continued to rise, eventually reaching 100 kilometers/second. A hundred seconds later, the super fighter jet reached an orbit 10,000 kilometers away from Earth.

From the moment the super fighter jet began transforming and taking off from the surface of Dream Island to arriving in outer space and reaching a space orbit 10,000 kilometers high, the super fighter jet took less than 3 minutes, showcasing extremely efficient flight.

Upon reaching an altitude of 10,000 kilometers, the super fighter jet activated its quantum radar. Although the drone carrier is equipped with quantum communication and quantum satellites for ultra-long-distance detection and communication, quantum radars are still installed on the super fighter jets and transport aircraft. Compared to the previous Level 5 drone, the super fighter jet's quantum radar had greatly improved performance, with a maximum detection range of one million kilometers. With such a scanning range, a single scan from the super fighter jet provided a comprehensive understanding of everything above Earth.

The main reason Yan Fei encountered ambushes from the American Energy Weapon Launch Platform twice, placing himself in extreme danger and nearly facing demise, was his inability to monitor this energy weapon launch platform.

Due to performance limitations, the previous Level 5 drone couldn't enter space, and its quantum radar couldn't scan space targets. Additionally, the energy weapon platform possessed dual radar and optical stealth capabilities, disappearing and hiding after each attack, making it impossible for Yan Fei to locate it. Otherwise, with Dream Island's formidable anti-satellite capability, the energy weapon launch platform would have been destroyed long ago.

Harboring this grudge, when Yan Fei gained the ability to enter space, the first thing he set out to do was locate and completely eliminate this energy weapon launch platform. This was not only to resolve the threat it posed to Dream Island and himself but also to avenge Xia Fan.

Although Yan Fei didn't like Xia Fan, Xia Fan was, after all, killed by the energy weapon launch platform for his sake, so he had to avenge Xia Fan.
