Nuclear-powered Sword Immortal - Chapter 15 - Knowledge is Power

In a post-apocalyptic fantasy world layered into multiple realms, humanity faces extinction due to their endangerment of the main realm. Forced to merge all realms back into one, a deity grants humans a leveling system to empower them, lest they become extinct when facing the mythical creatures. Noah, our protagonist, embraces the role of a monster tamer, trading his humanity for strength and eventually transforming into a monster himself. As Noah struggles with his evolving identity, he must navigate a world where the line between human and monster becomes increasingly blurred.

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

Encountering a car crash, the King of Silver Screen, Ye Sinian, was bound to a Cannon Fodder Counterattack System.

After reincarnating for hundreds of lives, he has finally earned enough “travel expenses” to go back home.

However, he didn’t think that the system would suddenly malfunction, making returning back home from then on hopeless.

With the shackles of a millennium broken, Ye Sinian aggressively counterattacked!

Reversing fates while hugging the mentally ill* Lord Seme, he walked towards the apex of humanity!

*Mentally ill – Schizophrenic
