Chapter 451: Chapter 219: The 4th Upgrade_3 Chapter 451: Chapter 219: The 4th Upgrade_3 However, as Yan Fei grew closer to the core circles of the world, the enemies he faced became increasingly powerful. The F-15-shaped Drone was clearly insufficient in strength and could no longer help Yan Fei achieve more glory. Therefore, the Drone had to be upgraded, and even though Yan Fei had deep feelings for the F-15-shaped Drone, it was time to part ways with it.

Touched, Yan Fei stroked the cold body of the Drone one last time, then, without looking at the Drone, he pressed the upgrade button, now red, on the virtual control screen. As Yan Fei pressed the button, the red upgrade button flashed and disappeared, and then everything went black before his eyes as the consciousness attached to the Drone was ejected from the virtual control screen and returned to his own body.

The Drone body hovering above Yan Fei's head trembled, and a wave of terrifying power that could destroy heaven and earth suddenly appeared, sweeping in all directions. This indescribable terror ripped a huge hole in the dense fog that had lingered above Misty Island year-round, allowing the starlight to completely bathe the island for the first time in thousands of years.

Yan Fei was terrified to the core, even his soul shivering in fear. In a panic, he instinctively covered his head with his hands, only to discover the terrifying wave suddenly receding inward, concentrating into the raw materials piled on the island. Feeling somewhat relieved, Yan Fei immediately jumped into the nearby sea to avoid the terrifying wave.

The raw materials were rapidly disintegrated into fine particles under the influence of the terrifying wave, converging in the air to form a brilliant stream of particles. As more particles joined, the stream grew thicker and larger.

Yan Fei, in the sea, marveled at the spectacle of the particle stream and found it both awe-inspiring and beautiful. If not for the fear of the terrifying wave, he might have taken out a camera to capture everything. However, the Universal Space was inaccessible at the moment, and Yan Fei couldn't retrieve anything from it even if he wanted to.

The particle stream swiftly grew larger as it began to swirl around the Drone Avatar suspended in mid-air. Suddenly, with a twist, it plunged into the Drone Avatar. As the Drone incorporated the particle stream, it began to transform; its entire body melted as rapidly as snow in the blazing sun. Ultimately, the Drone turned into a huge transparent liquid, floating in mid-air and constantly changing shape. As more of the particle stream merged with the transparent liquid, the shape shifted rapidly but seemed unable to solidify.

Though Yan Fei watched anxiously from the water, he wasn't too worried thanks to his previous experiences with Drone Upgrades. However, the increasingly stringent conditions for the Drone's upgrade only deepened his confusion about its nature and origins.

The materials required for the Drone's past upgrades varied, but none had required bio-materials. Yet, this upgrade called for bio-materials, and a massive quantity of ten thousand tons at that. Could it be that the Drone wasn't just a cold metal fighter jet, but it could become a living biological one? And what was that terrifying wave disintegrating the materials? Why did it invoke such horror? The shivering of his soul was a feeling Yan Fei had only experienced once before, when he met Gu Xiaolan. Could there be some connection between her and the Drone?

As the particle stream continued to merge, the volume of the transparent liquid in the air grew larger, resembling a surging river. Eventually, the terrifying wave stopped disintegrating the raw materials and violently retracted into the transparent liquid. Without the wave, the decomposition of the raw materials on the island ceased and the dazzling particle stream disappeared.

The particle stream might have stopped, but the transparent liquid in the air continued to shift shapes. Ultimately, it emitted a blinding white light, appearing like a colossal Sun materialized out of nowhere. The intense light forced Yan Fei to tightly shut his eyes to avoid being blinded. The white light shot into the sky, dispersing the fog within a several hundred-kilometer radius.

Yan Fei was secretly alarmed, worried the secret of the Drone's upgrade would be exposed. Just then, the white light shrank inward and vanished. At that moment, a vague shadow flickered beneath the waters of Misty Island Sea Area and merged into the transparent liquid – a sight that Yan Fei, eyes closed, missed.

As soon as the ephemeral shadow appeared, it seemed as if something extraordinary had happened in the world. The world's strongest individuals immediately sensed something and went on high alert, although they couldn't pinpoint what had changed before it disappeared. These mighty beings heightened their vigilance…

It wasn't until Yan Fei opened his eyes that he saw everything return to normal. The only difference was the enormous fighter jet suspended in mid-air before him, the very B-2 Stealth Strategic Bomber that he had gone through great lengths to scan. At last, under the influence of a Mysterious Power, the Drone's fourth upgrade was successfully completed.
