When faced with the Shadow Ghosts, all Dean McKenzie could do was upgrade his skills.
Currently, Dean held two Grant Quotas in his hands, but there were hardly any skills that could be upgraded to deal with Shadow Ghosts.
After all, Dean's only attack skill was Bone Fang, and it couldn't be upgraded.
After scanning through his options, the only thing Dean could upgrade was Summon Skeleton.
"Upgrade Summon Skeleton. Enhance Old Seven. Old Seven's Little Nether Flame Ball can damage the Shadow Ghosts!"
Once he had made up his mind, Dean didn't immediately open the attribute panel to enhance his skills.
Instead, he first approached the six Excellent Template beasts that had already been finished off, and used Extraction on them.
"[You have successfully extracted attributes from six Excellent Template beasts, gaining 60 attribute points, and six pieces of Excellent Template fragments.]"
"60 attribute points? It seems that the upper limit of level 2 Extraction is 10 points."
