It's an isekai systemverse, the MC only has healing powers, no offensive/defensive or any other types.
I *think* he uses his knowledge of anatomy to heal, as he was a doctor in his past life.
I *think* he healed over someone's wound with an item so that the item would be stuck in the person.
I'm sorry, I know the details are vague, so honestly if you know any MC with just healing powers in a systemverse, please link it here so I can comb through them and find the one I'm looking for.
