I Transmigrated Into a Red Dragon and Raised a Silly White Dragon Little Sister

Alternate title: You were supposed to raise a useless dragon girl, so how did you become the God of Fate? Transmigration + another world + magic + farming + one heroine + loli + dragons I transmigrated as Helgas the Red Dragon and got saddled with a white dragon little sister with a low IQ. From then on, my dragon life of conquering the world became a daily routine of stopping her from chewing on my tail. Then one day, a loving lick from her unlocked the [Threads of Fate] within me. It suddenly dawned on me: I wasn't raising a little sister. I was raising the “causality switch” that triggered a god-tier cheat! With my little sister bringing in the loot and the occasional flash of inspiration from my “prophetic dreams,” my dragon life was easy and full of magic. Later The ancient dragons awakened and plotted for a thousand years, yet always fell short at the crucial moment. The dragon-slaying clan drew their holy swords, only for every last one of them to trip and fall flat on their faces before the dragon's lair. The Empire's archmage brandished his staff, his incantation abruptly cut short by a devastating backlash. “Who tampered with my spell model?!” The mighty ones who stood atop the world roared in fury, trying to control their fate. But I, the greatest astrologer and a red dragon dad, had simply seen every script in advance. They scoffed: “Astrology? Just a con!” I only smiled in silence and secretly plucked the [Threads of Fate]. While you're busy calculating everything, I've already given the strings of probability a gentle pluck.
