Sure enough, the master's things are not so easy to steal.
Feixue wanted to rely on her ability to be invisible and steal her mission supplies, but she didn't want to steal the chicken but lose the rice. She was caught by a certain god and was forced to sign a "selling herself" contract to become a certain god's exclusive milk bottle...
However, it seems that it is not bad to be the master's exclusive milk bottle. You don't have to worry about the master's blood volume at all. Not only can you gain the experience of the master's bodyguard, but you can also improve your life skills (while the master is fighting monsters, Feixue is making medicine on the side...)
