My 100th Rebirth a day before the Apocalypse novel Chapter 305

Colored and rainbow crystal cores aren’t essential in the early stages of superhuman development, as normal crystal cores are sufficient for leveling up at first. However, as superhumans advance, it becomes increasingly difficult to progress and break through bottlenecks to reach higher levels.

At that point, colored and rainbow crystal cores become invaluable, providing the extra power needed to overcome those barriers and achieve significant growth.

To break through these bottlenecks, superhumans not only need to be extremely lucky but also possess significant potential. Additionally, they require a substantial amount of colored crystal cores that align with their specific ability. Without these, progressing to higher levels becomes nearly impossible.

If a normal crystal core provides 10 spiritual energy when consumed and a level 1 crystal core gives 25 spiritual energy, a level 1 colored crystal core offers the same energy. However, if it matches the user’s ability, the spiritual energy is doubled or sometimes even higher.

As ability users reach higher levels, normal crystal cores become ineffective for further progress unless they are of a higher level.

Like zombies, humans also possess energy cores, but unlike zombies, all human cores are inherently colored and function similarly to zombie cores. This has led some superhumans to resort to killing other superhumans to harvest their energy cores, in a desperate attempt to advance and gain more power. This harsh reality only adds to the chaos and difficulty of surviving in the apocalyptic world.

That’s why superhumans eventually prioritize collecting colored crystal cores, using regular ones primarily as currency. At this point, Kisha had already obtained one colored crystal core from a previous zombie kill and one normal level 1 core. Now, she figured this rare rainbow crystal core must have come from the zombie that failed to fully awaken.

Kisha held the rainbow crystal core tightly in her hand, a faint smile tugging at her lips. "You like that kind of core?" Duke’s raspy voice came from behind as he wrapped his arms around her and pressed a kiss to her shoulder. "I’ll find more for you, alright?" he murmured, his tone full of affection, making Kisha’s smile widen.

The two remained in the room for a while, savoring the quiet moment together. When they finally descended the stairs, they were met with the sight of the Winters and their subordinates already gathered in the living room, concern etched on each of their faces.

As Kisha and Duke reached the bottom of the stairs, hand in hand, everyone exhaled a sigh of relief, though their anxiety lingered at the sight of Kisha’s bandaged body. It was only then that Kisha became fully aware of her condition—or perhaps she simply remembered the extent of her minor injuries. She gently touched the bandage around her throat, as if acknowledging the toll the battle had taken.

"Don’t worry, it’s just a minor injury," Kisha said with a smile. Unlike her, Duke’s expression darkened as his brows furrowed at her words. To call it "minor" felt wrong—he had nearly needed to stitch her throat from how deep the wound had been. But he knew Kisha well; she would likely down a vial of the blue healing liquid the moment she woke up, easing his concerns slightly.

She was already awake, but she still hadn’t taken the vial, so Duke gently reminded her, "Wifey, why don’t you take the vial of blue liquid? It’ll heal all your injuries instantly." His face was still etched with worry and a hint of sorrow as he spoke.

"I’ll take the vial later, but for now, we need to visit the medical facility and address the concerns of the people and the family of the deceased," Kisha said. It was only then that everyone realized her intention. None of them were naïve, especially the Winters, who had spent years in the business world.
