The tunnel was narrow. It was just enough for a single person to walk through comfortably, but not too tight. As Corey walked deeper and deeper into the tunnel, the temperature dropped.
But this temperature was not normal. It wasn't the type that truly affected one's physical body.
Instead, it affected one's spirit.
'Spiritual energy? And it's extremely dense?'
Corey furrowed brows slightly as he observed and analyzed the spiritual energy in the air.
Because of how dense the spiritual energy in the tunnel was, most people that could sense it would have rushed to absorb it so that their spiritual energy and mental energy could increase drastically.
However, Corey knew that the spiritual energy was impure.
Very impure.
It was like the spiritual energy was a mixture of several different spiritual energies that once belonged to several individuals.
Corey had his thoughts on what could be the source of the spiritual energy, but he decided to wait.
Corey looked at the walls.
