Suddenly pulled into a world filled with Specters, Fang Xiu woke up with a unique ability: Reset. Every time he died, time would rewind to the moment before he was killed.In this strange and dangerous world, Fang Xiu could have chosen to hide. Instead he announced to the world, “Yes, I’m a prophet. I can see the future!” As his predictions kept coming true, his title of the Prophet spread around the world.His words became the truth. They became the future.“I have seen the future,” he announced, attracting people from all around the world.His followers took it to the extreme, declaring, “Should the Prophet decree your demise one day, don’t waver, don’t question, just obey. For hesitance only leads to a far graver fate.”During a B-level Specter event, known as [the Spawning]A teammate warned, “The creature is hiding among these villagers. We need to be careful.”Fang Xiu pointed to the last row and commanded, “The one in white. Yes, you. Come out!”In an A-level Specter event, called [Lantern Heads]One teammate warned, “This area is crawling with thousands of Lantern Heads. If they shine their light on you, your head will fall off. The scariest part is the Lantern Heads float unpredictably. It’s impossible for anyone to get across safely. Wait, where’s Fang Xiu?”Another stuttered, “He, he…he’s on the other side!”The first teammate exclaimed in disbelief, “What?! How did he get across?”The other replied: “He…he just walked over.”

On a normal boring day, a message appears, inviting him to a Tutorial.

Rein Aster was just a herbalist farmer from a border village.A nobody. A background NPC in a story filled with prophecy and divine warfare.But by chance—or fate—he saves one of the 7 Demon Lords during a catastrophic war event. Instead of killing him, she falls for him.Obsessively. Violently. Eternally.And then… so do the others.Each Demon Lord tries to trap Rein as her personal lover/pet/priest/husband/god, building dungeons, illusion palaces, soul prisons—but Rein keeps escaping. Quietly. Cleverly. Never fully rejecting them—but never submitting, either.Why?Because Rein realizes something:The gods are worse than demons.The heroes are tyrants in shining armor.The world is collapsing—and he’s the only one they all listen to.So he hatches a plan:Use the Demon Lords’ love to take over the world.Pit them against the heroes. Unleash them on the gods. Make them fight for him. Make them kill for him. Then tame them all.Not as a king.Not as a savior.But as the lover they would burn the world for.__________The yanderes here are darker than what you might be used to.You have been warnedThe entire novel has a dark feel.
