Everyone is a hero, but I am a second-year player.

An Yi was reborn as the [Sword Hero], and after being killed by the Demon King in the final holy war, he opened his eyes and returned to the year he was born.
When he was eighteen years old, as the sound of [Brave System Activated] rang out, thousands of brave men emerged on the land.
They suddenly became powerful beings superior to humans, possessing high attribute bonuses, a system that can distribute rewards, and even powerful skills that ignore the laws of physics.
However, they all started from scratch, training in professional weapons and obtaining intelligence on the demons.
Only Anyi had full proficiency at the beginning, as well as knowledge of the demons from his previous life.
