1. First, save a game file. After you save your family in the database, separate the villain and open a new home for him, and then save it in the database again. Then start a new game (change another map to create a family), open the database and import the newly created villain family, and then you can modify the body shape, appearance and characteristics.
2. After saving the database again, put the latest villain back to his original home, and then you can start your career again after being transferred back. The sequela of this method is that the relationship list and personal items will be emptied and friends can reconnect. Books in personal belongings can be put on the shelf in advance, and other things can be put in the refrigerator or household goods list (the lower left corner of the construction mode).
This method can be used without any adverse effects. Interested children's shoes try it in the game quickly!
