The Most Difficult Evidence Collection in History

To the south of Beiqian City, there was a factory that had been abandoned for many years. Fifteen years ago, the fifth victim in the Devil Case fell from this factory building and died.

As time went by, many of the surrounding businesses closed down and went out of business. Hence, nowadays, only this building still stood here, as the other buildings the the victims had fallen from had been demolished or were replaced by new construction. None of them existed anymore.

This afternoon, Zhao Yu and several special investigation members had come here to inspect the old crime scene. At this moment, they were walking upstairs to the floor where the tragedy had happened.

Because the factory building was unoccupied and was in a bad state of disrepair for many years, Zhao Yu couldn't go up the steep stairs with his wheelchair. However, the stubborn man insisted on climbing to the crime scene using crutches.
