Under the vampire Lord's protection - Chapter 25: The secret room

In a world where fate is dictated by prophecy, heroes are chosen by the gods, and Dark Lords are doomed to fall… Lucian Draeven refuses to play along.Once feared as the greatest Dark Lord in history, Lucian had the world under his iron rule—until the so-called Chosen Hero struck him down in a blinding flash of divine justice. The kingdoms cheered. The world rejoiced.Too bad Lucian isn’t actually dead.Having faked his demise and gone into hiding, Lucian watches from the shadows as a new Dark Lord rises, more reckless and incompetent than ever. Worse, the gods have selected another overly enthusiastic, sword-swinging Chosen Hero to bring “peace” once again.The problem? Neither of them have a clue how to actually rule the world.As kingdoms crumble, wars break out, and the balance of power teeters on the edge of collapse, Lucian comes to a horrifying realization:If the world is going to survive, then it’s up to him—the so-called villain—to secretly fix everything from the shadows.But there's just one little catch…Lucian’s legendary Dominions are still sealed, and the only way to regain his strength is by playing the role of a villain once more—spreading fear, manipulating his enemies, and pulling the strings behind the scenes.Now, as the oblivious Hero and foolish new Dark Lord battle it out, neither realizes that the true mastermind is watching their every move.Because if the world wants a villain…Then Lucian will be the greatest villain it has ever seen.
