Reign of the Otherworld King with a Super Game System

Synopsis:

Ronald, once an ordinary young man from Earth, is unexpectedly transported to the world of Tianheng Continent, to the Kingdom of Sun and Moon. He finds himself in the body of the kingdom's namesake king, whose life was tragically cut short by a palace coup. On the night of his wedding, the king was betrayed, usurped, and fatally wounded by a poisoned arrow.

Upon awakening, Ronald discovers he's on the run, accompanied only by a small group of loyal soldiers and his trusted bodyguard, Fan Qingyue. But fate is far from kind, as Ronald's new world is filled with enemies, magic, and powerful forces. However, with the help of the Super Game System—his personal "Ring World System"—he begins to unlock incredible powers that could turn the tide in his favor.

Core Conflicts and Reversals:

Reclaiming the Throne: Ronald leads the remnants of his army to retake the kingdom from the rebels, using the system's tech and tactical brilliance (such as covert operations and strategic multi-front warfare) to gradually recover lost territories and uncover the conspiracy behind the palace coup.
Expanding Power: Starting from the Kingdom of Sun and Moon, Ronald’s conquest takes him across the southern frontier, facing the allied forces of the Divine City, the demon race, and even challenging the powerful god-tier factions, all while aiming to become the King of All Nations.
