If you had a golden apple, who would you give it to?Invited to the banquet, Luo En saw the golden apple in the plate inscribed with “To the fairest goddess” and the three goddesses embroiled in dispute before him, and he picked up a knife with a smug smile.The first step, peeling; he gave the skin to Aphrodite.“To be fair, you're quite pretty. As a layer of skin, you're not bad to look at.”The second step, slicing the flesh; he gave that to Hera.“As the queen of heaven, yet everyone in Olympus from 800-year-olds to animals has cuckolded you, including males, females, and even sheep. Since you can't save face anyway, take these insides.”The third step, he gave the remaining core to Athena.“You were supposed to be born a male god and take over Zeus's position, but due to Zeus's shenanigans, you lost that seed, so here, have this core.”Aphrodite clenched her fists, Hera raised her scepter, Athena summoned her spear and shield...Seeing this, Luo En quickly stepped back, shielding the goddess of discord, Eris, firmly in front of him.“And you still want to be the goddess of discord? Look at me; I got them to unite at once, even better than you with your instigation.”“...”Surrounded by Greek gods sharpening their knives, Eris was left in silence.
