Chapter 122: Me in the core (3)

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.
