I Am a Professional Trainer

The protagonist was reborn with a technological system. He thought he was reborn in an ordinary city, but he found out that this was a digital world. The introduction is written casually. As for the system, I added it if it felt interesting. However, it has little presence in the novel, or it can be said that it will not appear at all in the later stages. It will only be mentioned occasionally and will not appear many times. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
