Sure enough, after Ling Feng killed a Skeleton Warrior, he finally sensed something unusual.
When the Skeleton Warrior fell to the ground, a very subtle energy flew out from its skull and entered the skull of another nearby Skeleton Warrior!
And the Skeleton Warrior that absorbed this energy evidently became stronger.
"So that's how it is!" Ling Feng's heart sank. No wonder these guys were getting harder and harder to deal with; it turns out that every time he killed a Skeleton Warrior, its energy would enter the body of a nearby Skeleton Warrior, enhancing their power!
In other words, by the time Ling Feng fights to the last, he would be facing the collective strength of over eight thousand Skeleton Warriors!
This realization made Ling Feng gasp; he had only defeated less than a third of the Skeleton Warriors, and already he was somewhat caught up. If this continued, Ling Feng definitely couldn't pass this challenge!
