The Salted Fish Mage Who Stole the Brave System

A dead house who traveled to a different world thought she would just change her identity and location and continue to live in the house. However, an accident full of doubts forced her out of Novice Village. In the process of retrieving her relatives, she slowly discovered some unknown things. A system full of doubts, a deliberately modified magic system, gods that seem to exist in real life, and his own time travel. As a salty fish, I obviously just want to lie at home doing nothing, but I still can't do it. What should I do?
