Tunnel

'Fuck, that was close,' I thought.

I don't know how the monster was able to sense me, but it did and chased me with everything it had.

Thankfully, the sphere could move fast when it needed to, but used a huge amount of energy and forbidden power that I couldn't supply.

I needed to use the forbidden power that was stored in my core.

Every day, I store part of the forbidden power. I have been doing that for years and it saved me a lot of trouble like this one.

It had been over nine hours since I had started and now, I am close to the place where the Grimms are mining, and I have already decided on the place from where I will come out.

A few minutes passed, and I have reached the exit point. It will be the first time I will come out of a place that is made by the beings.
