Hercules, a brawny demigod with a knack for trouble, faced his second challenge - the Lernaean Hydra. This wasn't your average beast. Imagine a swamp monster with nine venomous heads, snapping and hissing. The real kicker? For every head lopped off, two more grew back! Yikes. Undeterred, Hercules, with his trusty club, charged. He'd whack a head, but two more popped up. Frustrated, he called upon his nephew, Iolaus, for help. Together, they devised a plan. Hercules would smash the heads, and Iolaus would sear the wounds with fire, preventing new ones from sprouting. The stench of burning flesh filled the air as Hercules whacked and Iolaus seared, the teamwork slowly whittling down the hydra's fury. Finally, only the central, immortal head remained. With a mighty swing of his golden sword, a gift from a goddess, Hercules severed it. The hydra, defeated, twitched its last. The hero, battered but triumphant, dipped his arrows in the monster's poisonous blood, forever staining them with the mark of victory.
