Afterward, Luo Zhen remained in the hospital room and chatted with Nagisa for quite a while.
For lively and active Nagisa, having someone to chat with was already something worth being happy about. Not to mention, the girl was quite talkative. As long as she could chatter away all day, she would feel completely satisfied.
That was why Luo Zhen and Kojo came to the hospital almost every day to keep Nagisa company. Apart from visiting her, they mainly wanted to chat with her and help pass the time.
Of course, Luo Zhen did not stay at the hospital for long. Having a curfew that required him to return home before dark was a truly miserable thing. Only Kojo would remain there the whole time, sometimes even spending the night at the hospital. He was quite considerate that way.
In any case, with their father away from home and who-knows-where investigating something, and their mother frequently absent as well, if Nagisa was hospitalized too, Kojo would only be returning to an empty house. He might as well stay here.
Thus, after chatting for a while, Luo Zhen began helping Nagisa with her routine soul-calming and exorcism.
Although it was called soul-calming and exorcism, what it actually involved was first hypnotizing Nagisa and putting her to sleep, then chanting soul-calming incantations for half an hour to stabilize Nagisa herself and the spirit within her, before cleansing her body and mind with exorcising sorcery.
In this way, Nagisa's spirit would gradually stabilize, while the intruder within her would be weakened in the opposite manner. Once it became weak enough that it could no longer wield powerful forces to resist, much less control Nagisa's body, it could then be exorcised in one go.
This was the most stable, safest, and most reliable method.
