What are the conditions for reincarnation of stray pets?

No, pets have many tasks. After the last related task is completed, pets will "leave the team forever" (scare people, which will be explained in detail later)

For example, Xiaolan will become a constellation and leave the player team after completing "Innocent Girl" (+Goodwill Mission) and "Giant Spider" (Death Mission). After that, you can go to Chris Village to talk to the pastor in the church, and then you can get Xiaolan back to your team by consuming a certain number of "stars" obtained from the task. Such Xiaolan is the partner of the "Kill Mission", and then you only need to train her to 65438.
