During the attack and defense process, special tactical props can be used, such as the "Mist Scroll" which can temporarily obscure the enemy's view and allow our own troops to quietly approach the castle; The 'emergency tent' can continuously restore the health of our own soldiers on the battlefield; The "Siege Hammer" can quickly destroy the wooden or stone walls of a castle. These props need to be unlocked by completing level tasks or accumulating resources. Reasonable use can greatly improve the success rate of attack and defense.
