Since she couldn't choose or even determine the time and place of her arrival in the Fourth Realm, Xin Huohuo wasn't too concerned about when she departed.
The next morning, she went on a shopping spree at the supermarket, stuffing Xiaohong's trunk to the brim. Then she gave Xiaohong a bath (i.e., a car wash) before driving to a deserted spot in the suburbs.
'What if I end up in the middle of nowhere? Stocking up on some food, drinks, and daily necessities will make things more comfortable.'
'She didn't know if the mysterious road to the Fourth Realm had network coverage, or what she would do if she lost her signal halfway there. But she knew she wasn't a normal person anymore, and the world she faced was no longer just the normal one. So, it was best to find a place where no one could see her. What if Xiaohong suddenly went berserk? She didn't want people to mistake Xiaohong for some crazy race car.'
As it turned out, her decision was incredibly wise.
