Because the vast majority of low-level adventurers in battle inevitably get injured, without the timely aid of medical personnel, at worst, they might die from poison infection, at best, they suffer weeks of pain, severely affecting subsequent adventures and explorations.
After basic treatment is completed, the injured are quickly carried on stretchers into the corresponding tents for further care.
This way, injuries that would normally take several weeks to a month or two to heal naturally might recover in just a day or two.
Of course, this is the kind of treatment only adventure groups receive. For those lone wolf adventurers or squads without medical professions, they need to rely on others' goodwill, pay a sum for treatment, and even then, it depends on whether the priest has time.
After all, priests with teams have to wait until their main job, that is, treating their teammates, is finished before they can take on private work.
