Sylas took out bottled water and gulped it down.
The recent fight with the high-level zombie almost cost him his life.
Sylas wiped the water away from his mouth and slowly walked towards the head of the high-level zombie.
Slash!
The spatial blade cut open the zombie's head, and a white-colored energy stone rolled out from the zombie's brain matter.
The energy stone was a little bigger than the size of a marble, but Sylas could feel the energy radiating from it. It was stronger than any other energy stone he had come across so far.
He used the remaining water from the bottle to wash the energy stone and immediately tossed it into his space.
Sylas waited for a few seconds, but apart from his space absorbing the energy stone and the recovery of his depleted energy, no new changes happened.
'Looks like I will need more energy stones if I want to upgrade it to level 4,' Sylas thought.
Sylas decided to count the levels, so he simply used numbers to keep track.
