Xue Dili had once visited the church, not referring to himself, but the Xue Dili from the parallel world, the double doctorate from Boston, who experimented thousands of times to research bacteriophages that could counteract the Divine Tree, that Doctor Xue Dili.
However, at that time, he was in America. In order to obtain experimental materials, Doctor Xue had to contact a group of professional corpse collectors to acquire experimental materials, which also allowed him to obtain data on Divine Tree ashes infection.
Yes, America had a specialized profession called "corpse collectors," and they were not considered a lowly profession but rather a particularly respectable and prestigious one. Typically, only church priests or professionals from medical universities could join this line of work.
Xue Dili often interacted with the priests who brought him corpses, and sometimes what they brought weren't even corpses but elderly people who had only a breath left.
