Chapter 179: The Snake's Blade

Evan was an experienced demonologist and was adept at harnessing the power of many demons. As a price for their power, demons demand the life force of the person summoning them. When Evan first harnessed the power of the 72nd demon, Count Andromalius, he spent almost all of his energy on it, but he didn't need to give up years of his life as payment. It took Evan several days to regain his energy back then.

However, when Evan became a magician and broke through several "Barriers," he could already use Count Andromalius' power using only a certain amount of energy. It became more like a spell that required a lot of mana and stamina. But after using it, he could still continue to fight.
