My Monster Fuses Everything - Chapter 641 - 416: Battle of Cliffshore Mountain_2

An ordinary young man reincarnates as Adrian, the eldest son of a once-prominent noble family now living out in boonies of the kingdom. Watch as Adrian embarks on a tantalizing journey, to support his graceful and caring mother and feisty older sister, as a man should, with his seduction system.

Emperor Ian Veroshion, the first noble mage, was betrayed and executed. Cursed to never be reborn, he awakens a century later as the illegitimate son of a disgraced ducal line, destined to be a hostage in a barbaric land. Stripped of his magic and his throne, he must navigate a world vastly different from the one he ruled, facing political machinations and a resurgent monster threat. But the embers of his past life still burn, and Ian will not surrender his legacy. He will reclaim his name, his magic, and perhaps, even his empire.
