The difference between the three realms of Fantasy Westward Journey and the ordinary zone is mainly reflected in the following aspects:

Server capacity: The server capacity in the normal area is larger, which can carry more players online at the same time. However, the server capacity of swordsman is relatively small, and the number of players that can be accommodated is correspondingly small.

Player group: Due to the limitation of server capacity, the player group in the Three Kingdoms of Swordsman is relatively small, and there may be less interaction and communication between players. There are more players in the ordinary area, and the interaction between players is more frequent.

Activities and copies: It may not be easy to find enough players to team up to participate in some activities or copies like ordinary areas in the three realms of Swordsman. This may limit the player's experience in these activities or copies.

Competition: Due to the small number of players in the legendary swordsman, some resources or rankings may be relatively easy to obtain. However, this may also lead to less intense competition and lack of challenges.

It should be noted that these differences may change due to game version update or operation strategy adjustment. Therefore, players are advised to consider the server comprehensively according to their own game needs and actual situation.
