Alex helped many people, but not as many as he would've hoped to help. There were perhaps too many healers in the festivals and all of them were doing their work quite well, helping people that came to them.
He still helped all those who came for him, all of whom left happily. Another person came by and stayed next to him, watching him heal another person. They left once the person was healed.
Alex was very much weirded out by the experience, but it didn't take him long to realize that these people were making sure he was actually a healer and not someone giving away fake pills to people.
Once he understood that, he did not mind the many people who came for his help.
Most of the people who came were people with weak cultivation bases and ones who could not afford to pay to get healed. Everyone had their own problems and money was one of the many problems for them as well.
