This is a world invaded by ferocious beasts. Dragon-level and god-level beasts constantly threaten humanity. Upon reaching eighteen, humans can choose to awaken their talents. Once a talent is successfully awakened, they become powerful and defend against the monsters. Jiang Lan, a time traveler, is shocked to discover that Saitama's and Superman's talents are classified as D-level! While others strive for S-level talents, only Jiang Lan knows that Saitama and Superman, with their D-level talents, are invincible. During the awakening ceremony, Jiang Lan, having traveled through time, was given the choice of two talents. Without hesitation, he chose to awaken both Saitama's and Superman's talents. "Haha, this idiot chose a D-level talent." "I'm stronger even if I go bald, so I'll just turn him into a bald loser!" Faced with ridicule, Jiang Lan silently persevered with his training. A few years later, facing the invasion of god-level beasts, the nation wailed. Jiang Lan crushed them to dust with a single punch. Everyone was silent. This, this isn't right... and his invincibility was just beginning!
