Following the clues, she finally found a pet shop where she started to live and work. During this time, she discovered more and more things she couldn't explain.

To this day, she witnessed her grandmother's body dissolving like smoke in the Tomb of the Grim Reaper...
When Lin Xue recalled everything, her figure had already returned to its normal state.
"Grandma..." Lin Xue looked at the old woman beside her with a choked voice, knowing that this was her grandmother's final farewell.
