In this game, the monarch will face many death problems, such as the end of his life or being assassinated. Whenever these situations occur, there will be an option in the game to establish a heir, which will make the country more powerful. Stable and reduce internal suspicion, but everyone should also be careful not to open the option of fighting for the crown prince, otherwise it will be like various TV series, where the princes fight for the throne with swords.
Everyone must modify this option in the archive. If the princes compete for the throne, your land area may be reduced a lot and the country will be divided into many small parts. Therefore, when playing this game, you must work hard to maintain the country's policies and complete the plan as early as possible, but you must pay attention to modifying the game options.
As long as you modify the save file, you don't need to lead troops to suppress those rebellions. Otherwise, the national strength will definitely be less than before, adding instability to the game.
