In the stairwell.
Du Wei frowned as he looked at Ryan, the psychiatric patient above him, and directly took out the lighter that could deal with the Evil Spirit.

It didn't ignite...
This lighter, given by Father Tony, was said to be something that could deal with Evil Spirits. But if it didn't encounter an Evil Spirit, it usually wouldn't light.
Since it came into Du Wei's possession, aside from a few instances of close contact with an Evil Spirit when it had been used, it mostly served as a warning light.
Now, under the state of Spirit Vision, Du Wei didn't notice anything abnormal about Ryan, and the lighter didn't ignite either, confirming that the other person was indeed human.
So, it should be certain that the abnormality with Ryan's corpse that he had dissected appeared after dark.
At this moment, Ryan standing at the top of the stairs in his patient garment urged, "Hey, why don't you answer me? You should be heading back to the ward now."
