After doing some experiments, Billy confirmed that he could control the mana inside those objects since they were originally his mana. Like, he could make a spear sharper or a ring more durable, but it only worked for a time since the mana would be used over time. Still, that didn't grant him the skills that he wanted. The question was: how he could make that into a skill that could heal wounds or cure diseases.
"If only I could control my mana better…" Billy thought.
Billy realized that since his control wasn't that good yet, he couldn't just easily come to answer… even though he had the extra power granted by the rings, that much power wouldn't solve anything unless it is offensive-oriented. Billy couldn't just think: go combat diseases, oh mana… or maybe he could if he changes his perspective a little bit. While the human body was more complex, Billy could find things underground by using his mana to detect things out of place. Could he use that same theory on a human body? After a few days of testing it, he decided to make his move.
"Can I touch your head for a moment?" Billy asked.
"... Why?" Kate asked while frowning since Billy asked that his friends didn't come on a day.
"I just want to check your temperature. You look pale again," Billy said.
"All right… just don't do something weird," Kate said.
"It seems someone is getting carried away after being praised a few times," Billy said and then shrugged.
Billy touched her head and then used Mana Infusion, it was a bit different than when he used Earth Manipulation, but he could get a good feel of Kate's head. He used Mana Infusion in his head as well and didn't feel anything weird comparing both. The problem wasn't in her head… Most Likely, it wasn't in her limbs either, so Billy had to check her torso. However…
You have learned the spell Check-Up.
Check-Up
It grants you the power to analyze a certain area of the target's body for impurities or curses.
Curses… while Billy was looking for something physical, it seemed that he could do that as well now. For some reason, he started to think that was the problem. In any case, that was a spell that no people around him knew, so Billy felt pretty proud that he achieved something on his own.
"Your temperature is normal, but let me check your back a little bit," Billy said.
"You are starting to scare me… could it be that you are finally lusting after my body?" Kate asked while hiding most of her body with her bedsheets.
"Keep dreaming," Billy said. "I am only interested in women above thirty who are a bit plump if you get my gist."
"Well, I am also only interested in tall and buffed guys," Kate said.
It was the first time that Billy had said out loud that he was into milfs, and he felt quite free after declaring that. In any case, Kate was obviously joking, and that was a good sign since she was so depressed because her situation hadn't improved in many years. Still, now, one could even see how lively she was.
In any case, Kate showed her back since she could tell that Billy had used his mana to do something. While she couldn't tell what it was, her senses were good enough for her to realize that it wasn't something harmful. Her magic skills were also pretty good, after all. Regardless, when Billy used Check UP on her, he sensed that something in her lungs was off… that kind of problem in the Middle Ages was, most of the time, deadly, so it was no wonder people from that world couldn't find a cure. Not to mention, what Billy felt wasn't quite… magical… or spiritual… in a negative sense. He had assumed that it was a curse, but then he recalled the Virus status that he saw thanks to Appraisal.
"Well now… her problems are in the lungs, what can I do here?" Billy wondered.
As long as he kept touching Kate's back, Billy could keep sending and controlling his mana. Still, could he solve that just by using his mana. No, that was too risky… even Billy couldn't imagine how to treat internal wounds that fast and without any inspiration. However, what if he put his mana into her lungs like he did with the other objects. He increased their properties for a short while, after all.
"With each heartbeat, the lungs will work to make her breath, but it shouldn't consume that much mana… let's see what will happen if I increase the capacity of her lungs with all my mana," Billy thought.
There was a chance that just making the organ that is being afflicted by the virus stronger wouldn't solve anything. Still, it was the only thing Billy could think of right now. In any case, while he was infusing his mana, he paid attention to Kate's complexion because too much mana from an external source in her body could be harmful as well. Still, he didn't notice anything out of the ordinary, even when he took things very slowly.
"I feel a lot better… What did you do?" Kate asked.
"A massage… just that," Billy replied.
"You didn't move your hands, though?" Kate said.
"There are certain massages that work by adding some pressure in some parts of the body," Billy explained.
Kate didn't seem that convinced, but she decided not to press that matter further. In any case, Billy decided to go home since he wouldn't be able to see any progress with her condition so suddenly. Considering that he didn't learn the skill for what he did, he probably didn't use the best method. That being said, it was the only method that he could think of right now and despite that, he was pretty confident.. He had no reason to be, though.
