The Age of Arcana was a fantasy web novel written by I Am Zhishui. The background of the story was set in an era where humans looked up at the stars and searched for life. On a certain lonely night, humans surpassed the threshold and discovered the tip of the iceberg of the endless universe. Thus, countless arcanists rose from the ruins and started the Arcane Era. In ancient times, the Grand Arcanist Emperor Yan created the Fire Arcane Art, and Chi You created the Wizard Arcane Arcane Art. Liu Feng was one of the main characters in the story. He started his own arcane journey. However, other than that, we don't know more about the specific plot and content of the Arcane Era.
