Magnus was reincarnated in a magic world. He led a simple life on Earth and that was something he liked rather than being dragged into conflicts or into adventures to save the world or something like that. He never cared to be the MC but hoped that he would have a pleasant life, much better than his previous life. Whether he could or not, read the tales to see. ---
I had only five days before the secret realm exit portal appeared and after that, it would be closed for a year. So I have to increase my pace of exploring the realm. If I can't find the deepest part of the realm, I have to give up because, once the exit portal disappears, I will be stuck here for a year.
The exit portal would be open for two days but it appears only in the outer region. So I have to explore the core as much as I can and return to the outer region or else I would be stuck here for an entire year, which is something I don't have on my agenda.
I decided to continue exploring without rest. With peak Tier-4 strength, I can afford a few days without sleep. I can sleep as much as I can after I leave this place but this is my only chance to be here. I won't be eligible to enter next year.
