Standing at the door of a tall building was a child in long clothes.
"Hello everyone, I am Tan Yi from room 0601 of Yuyuan Garden, Tan from Tanshui. This is my friend, Wu Yu."
"... Wu Yu, laboratory number 0615, known as 'humanoid volunteer' and 'special experimental subject'. Also, the director is a good person."
"Please take care of me."
What kind of story will happen in the construction building at midnight?
