Chapitre 304: Fighting Nightmare Knights, Eliminating Green Ghost Carter, Obtaining the Stone Heart! (5)

He realized that this energy core had only consumed about 2% of its energy.

"This way, I don't have to worry about the energy problem of Green Ghost Carter for the time being. Most of the time, I don't need him to use a First-Ring Spell. It won't consume much energy unless I'm in a combat state."

He recalled that Green Ghost Carter had summoned two Hell Strongmen back at Silent Harbor. Unfortunately, he had been too busy running for his life to think of this.

"By the way, I can get Green Ghost Carter to summon the Hell Strongman and kill it myself. Wouldn't that form a cycle?"

Levi suddenly thought of a problem.

However, the Undead Summoning spell could only be cast once a day. Levi could only experiment with it tomorrow.

Moreover, Green Ghost Carter had already become a living dead. Whether or not he could use a First-Ring Spell like the Undead Summoning that was much more complicated than the Soul Flame was a problem.
