I Only Work in Factories, but I'm a Killer

Ding Yi is a high school student who traveled to a parallel world when he was eighteen and became an orphan. Here, he had no parents who loved him, no younger brothers and sisters who were loved by him. In order to survive, he decisively chose to enter the factory. However, where there are people, there will be fights, and the remaining imagination and painful struggles together create a cruel reality. Until he met the woman, "she put the key in my hand, and my whole life changed."
