The Once and Last Conqueror (Demon King Litrpg)

Twenty years have passed since the demon king’s defeat. A new world order emerged in the wake of his tyranny, one built by the same summoned Hero who killed him. But the demon king never truly died. Stripped of his power, physical body destroyed, Regis survived in a weakened state where he lay dormant for years. When a mysterious System appears, it throws the land into chaos. Amidst this turmoil, Regis sees the opportunity he’s been waiting for—a chance to rebuild his strength and finish what he started. This time, he will not fail. This story features a demonic MC who uses both raw power and manipulation to achieve his goals. He's pragmatic, but not a murderhobo. Expect long chapters, a slower pace with long-term mysteries and extended foreshadowing, and an expansive world. Updates weekly on the weekend
