The units stationed in the fortress will not be attacked and cannot attack others. It will take one step to leave the fortress. If there are units around the fortress, they cannot leave the fortress. 2、 Undercover: 1. Insertion: At the beginning of the game, spies can be secretly planted in the other unit, and two ways can be selected: A. Two spies are randomly placed in the [Soldier], but neither side knows which one is the spy before the spy turns against the enemy. B. Insert a spy in the [minister], and the spy can be known by his side throughout the whole process. The spy can be upgraded, walked and attacked by the opponent normally, and can't do any operation before the enemy's spy turns back. 2. Backwater: It takes one step to reverse.
