Travel Through the Gods, but the Divine System

No one can be seen in the empty mountain, but people's voices can be heard. A senior graduate in the 21st century died suddenly at the moment of submitting his thesis. When he opened his eyes, he became a little girl from a well-off family in Hanyun City. She had a happy family and a sister who was twenty years older than her. Although she had to start over, she had a powerful system and had so much money that she couldn't even spend it all. But who can tell her that this is the world of God-Slaying! How could she survive in this dangerous world with a body so weak that she could barely carry a bucket of water? Throw money at it?
