At that moment, he was intently and slowly shaking the fluorescent green, water-and-light-like gelatinous liquid inside the bottle.
It continuously spiraled as it contracted toward the central point.
At its center was an eerie substance, green to the extreme and brimming with dense deathly aura.
"Slower, slower!" the gaunt old man kept muttering, his voice dry and piercing.
As he shook it, the liquid in the bottle gradually became a churning sphere of water and solidified toward the center.
Its mass grew heavier and heavier, and the condensed substance emitted radiation potent enough to make human cells collapse.
The concentration of this radiation was over a thousand times denser than at the very center of a nuclear explosion.
Any ordinary person who entered this Space-Time Loop would be pierced by the radiation as if billions of steel needles had entered their body, every cell in their body shredded apart.
Their body would collapse into a lump of mush.
"It's done, it's done, it's about to succeed—I can feel it, this is it!" The old man's expression was grave and gloomy, but his eyes grew increasingly excited.
He could sense that within the green substance in the bottle, which was about to condense into a solid sphere, an unusual aura was gradually emerging—one different from death.
The "trait" of nuclear devastation!
Though this trait was rather obscure and extremely niche—after all, nuclear explosions did not happen every day—no one could deny its power.
As long as he could perceive the deeper traits of a nuclear explosion and comprehend power deeper than the heat, radiation, and shockwaves of a nuclear blast—
Then, even without using the nuclear explosion energy spheres he had collected, he could enter the pseudo-Hell level. He might even use this space, which perfectly matched the "nuclear explosion" trait,
