Collapse I 

"Kach Thud Kach Thud Kach Thud…" 

It had been five hours since I had been digging into the stone mountain, and now I could completely pierce my sword into the stone if I wanted, which is entirely different from when I first starter where I my sword only dig a few inches into the stone.

Still, I am far away from reaching the entrance inside the stone mountain; it would take me at least tomorrow evening to do that; my current target is a hollow space inside, which is few meters away from where I am digging.

Seeing my speed, it should take me about two hours to reach there, but I don't I could. I am exhausted; the maintenance of enchantment at full power takes a lot of energy.

I had to refine the energy with all my efforts to manage the expenditure, and did I mention how much energy the enchantment took, its a lot that I am barely able to keep up.

I had to force myself to refine the huge energy, not matter tired I am feeling.

THUD!
