The full name of the Yuehua Sword is the Cold Light Yuehua Sword, which is a special artifact among the Genki Knights. If you want to get it in a regular dungeon map, it's basically impossible. If you want to get this ** quickly, after a specific Season starts, it is best to complete specific Seasonal Quests and purchase Artifact Chests.
Seasonal Missions: Every once in a while, the rewards will change when the Seasonal map in Genki Knight is updated. When a specific artifact in the Seasonal Map is the Cold Light Moon Sword, players only need to participate in the Seasonal Map and complete the designated tasks to obtain this artifact 100%. The difficulty of obtaining is the lowest, as long as there is no other way to consume additional costs in the normal game, the fly in the ointment is that you need to wait for the right season, the artifact of the current Gun Fighting Three Kingdoms season map is the Heavenly Sword, and players cannot obtain the Cold Light Moon Sword through the task.
Artifact Chest: After the Season Update, there will be a corresponding Artifact Chest, and if you have not yet obtained the Cold Light Sword after completing the designated task, you can try your luck by purchasing the Artifact Chest. This method is also very convenient to obtain a specific artifact, but the cost of obtaining it is relatively high.
As long as you get the Yuehua Sword, it will be much easier to continue to use this ** in the future. As long as you have enough materials in your hand, when you want to use them, you can go to the forging table and make them directly.
