A brief description of the manhwa Disciple of the Three Kings: By chaos, the world began to be invaded. One day, gates suddenly appeared in the world, unleashing monsters upon humanity. The situation brought humanity to the brink of extinction. The martial world of “Eun,” the world of magic and knights “Einhart,” and the world of demons “Gehenna” became interconnected, and superhumans from these worlds swept away the monsters. However, they were not righteous saviors. Under the law of survival of the fittest, the newly emerged “Players” of Earth were oppressed. Lee Ro-Woon sought to mediate between the Players and the superhumans from other worlds, aiming to bring peace to the world. But due to the discomfort of the superhumans from other worlds with his actions and the betrayal of his comrades, Lee Ro-Woon lost everything and fell into ruin. At the moment he was about to give up everything, he became the vessel of chaos and was transported to a sealed world. There, he encountered three supreme beings. Lee Ro-Woon becomes the disciple of the Three Kings and rises to rule over everything!
