Ghost Doctor: I Have a Ghost-Catching USB Interface

Twenty centimeters diagonally below Zhou Dao's tail vertebra, there was a small rectangular red birthmark. Before his death, his grandfather told him that there was a USB interface, which was the ancestral entrance to install the ghost hunting program. Zhou Dao went to the hospital to have someone perform a minor surgery. He made an incision along a small rectangle and inserted the weird U disk that his grandfather gave him. Then, Zhou Dao's life changed dramatically. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
