I, the Eternal King of the Elves

Traveling through a fantasy world, he became a member of the elves with a life span of thousands of years. And, see the golden finger of the chronology of history. In the year 582 of the Golden Age, the main city of the elves fell, and Elfin Willan died. "In this case, then leave this city early." As a time traveler, Al thought calmly. "Anyway, the elves have a lifespan of thousands of years. Only by living can they become stronger." From then on, Al, who was later called the Immortal King, embarked on an adventurous journey. "When the enemy advances, we retreat; when the enemy is stationed, we harass; when the enemy is tired, we attack; when the enemy pursues, I flee." "I will upgrade alone." "If you are weak, you will be good for yourself; if you are strong, you will benefit the world." Tens of millions of years later... Historians analyze history books. "In the first era, when the coalition forces of all races were retreating, he was the ray of light that pierced the darkness." "He has lived through countless epochs. "He is as powerful as the gods. " "He is the immortal supreme king of the elves—Elfen Willan! "
