It takes five days for a 500-level sword to be listed in the Book of Mountains and Seas. The Sword Record of Shan Hai Jing is a large 3DMMO fantasy mobile game based on the brand-new theme of Shan Hai Jing. The official of the game can only upgrade to 100 on the last day for the sake of not having a high degree of game liver and fearing that there is a big gap in player training, so it takes five days to upgrade to 500.
