White Dragon: Infinite Evolution, Starting with Dice Rolls

(Covering my bases here: a pseudo-DnD, a mixed-up setting, and the author has never been a dragon, so please go easy on me QVQ.) Oz transmigrated into a fantasy world, only to become a white dragon, the disgrace of the “Five-Colored Dragons.” Worse still, from the moment he was born, he found himself in a village that hated white dragons. Fortunately, at the critical moment, Oz was astonished to discover that the twenty-sided die that had arrived in this world with him possessed wondrous power. 【You attempt to persuade the enraged villagers of Frost Village. Required roll: 14】 【Roll: 15. Check successful. Experience +3. Success rate greatly increased.】 【You want to find the human girl lost in the forest. Required roll: 8】 【Roll: 20. Critical success. Experience +3. The System has automatically plotted your route. Navigation activated.】 【Total experience reaches 20. Choose one of three specialization upgrades.】 Years later, when the rift to the Abyss reappeared in the mortal world and the Old Ones invaded the Astral Plane, Oz, now a Dragon God, faced them without fear. “All your life, you strive to change the fate that has been set for you.” “But my fate is in my own hands.” Gazing at the die, every side of which had become a “20,” he murmured softly.
