Night Bull

"Yellow region," I said as I crossed the thin spatial boundary, appearing on the other side.

For a moment, there was no change, before one was suddenly hit by a powerful energy.

The yellow region is one of the three most dangerous regions among all opened and closed regions of this realm. It has a powerful energy; that only Earth Sovereign could survive, and Sky Sovereigns have been spotted here.

This place had a fluctuating restriction. Most of the time, they remained in Earth Sovereign but sometimes stretched into Sky Sovereign.

The place I am going to is a reason for that. It is also considered the most dangerous place in this ruin.

If I had any other choice, I wouldn't have gone there, but I didn't. 

It is that using organization doors, which I am unwilling to do unless I have no other choice.

I took a deep breakthrough and started moving again.
