Hell Difficulty Tower

Seven towers, hundreds of stories tall, appeared across all seven continents overnight, welcoming all who dared to enter. Each challenger was forced to choose their path: [Easy], [Hard], or [Hell]. The rewards were beyond human imagination. Normal people became godlike overnight—teleporting thousands of kilometers in a blink, reading minds, and shattering mountains with a single strike. But while the [Easy] difficulty handed out cheap power, it left humanity weak where it mattered most. When the tower released its monster waves, the so-called "kings of the world" crumbled. Humanity was completely eradicated. [You are the last survivor of humanity.] [Do you wish to turn back time and start over?] The last survivor of the [Hell] difficulty stared at the floating messages, wiping the blood from his eyes with a bitter sneer. "So those Easy-mode pieces of shit really all died. Acted like gods, but couldn't handle a single real wave without me." He reached out and pressed the screen. "Fine. Let's do it right this time." --- Disclaimer: Written in 1st POV with occasional POV changes.
