Infinite Domain of Doors

Lin Ranyi summed up three rules for himself: 1. The door is infinite, it is infinite. Second, he is limited, and he never feels that he is infinite. 3. Can't stop, can't stop, can't stop! So, he picked up cans at the end of the world, had dinner in a home where "he didn't exist", and became the only tourist in countless vast worlds. His only hope is to return to the home where he and all his family members exist.
