After Rebirth, I Used Mirror Reversal For Vengeance

50 years after the game world merging with reality, a top warrior appeared. He devoted his Whole life to the world, yet was ultimately killed by the king out of fear and jealousy. Before his death, he awakened the mirror ability and sealed his soul beneath the lake’s surface. The king covered up the true history and fabricated a new one, branding the warrior as a traitor in the eyes of the world. Decades later, the warrior awakened in the body of a dying man and began his vengeance using mirror ability.
