Modern office worker Rayne accidentally transmigrates into Adrian, a deposed prince of a Western fantasy kingdom. The original prince was framed for treason by his cold-blooded regent elder brother, stripped of his right to the throne, and had his royal magic crest branded away in public. Exiled to a brutal mine, he was also publicly dumped and humiliated by his former fiancée, becoming the kingdom’s laughingstock. Trapped in despair, Rayne awakens Ellarion, an ancient sealed elf within him, forming a symbiotic pact. He gains overpowering elven magic in battle, yet each fusion costs him life force and memories. Pretending to be useless, he stages a stunning comeback in the border mine, discovers a lost vein, seizes control of the military supply chain, and defeats all who bullied him. Gradually, he uncovers the shocking truth: his elven power and royal core magic seal were stolen long ago by his brother and dark-robed mages. Leveraging his fused magic, Rayne maneuvers among the black market, border troops and the temple, dismantling his enemies’ schemes layer by layer. At the coronation’s final showdown, he returns triumphantly with the border army and merchant alliance. He exposes all crimes, clears his name, achieves complete magical integration, and awakens the true royal crest. He dethrones his usurping brother, humiliates his fair-weather ex-fiancée, overturns the kingdom’s order with overwhelming strength, and ascends to the supreme throne.
