Qing Wen E Wang Zhi Hua

Xia Hexuan accidentally lost his sight at the age of 10, but miraculously regained it one day when he turned 19. He always felt as if he had forgotten something important. One day, he was pulled into a game called 'Pandora's Prison,' where the system told him that if he could collect three shards of hope, he could grant one wish. To recover his lost memories, Xia Hexuan began his journey into the game.
