Yan Luoli is a soft girl who found herself in a dream one night and couldn't get out. Yan Luoli felt vaguely that she had fallen into a strange world, but she believed that there would eventually be a way home. Fortunately, Yan Loli found a street boy who looked very much like her brother, and Yan Loli took him on the road. By chance, Loli picked up an agate stone. After wiping it, she discovered that a one-meter-long red mailbox popped out of the agate stone. It could also talk! "Hello, I am the mailbox god. I am your master. From now on, you have to obey me." Yan Luoli was immediately dumbfounded. What kind of plot routine is this? Even when I meet the magic lamp, it should be said that I am its master. How can I become a slave for no reason like this? Yan Luoli already had a tough personality and said no immediately. But the times were overwhelming, and then they started an adventure trip for the three of them.
