This Yue Feng was naturally He Feng, who had hidden away when Su Ming left the battlefield outside Sky Mist City. This person had swallowed a Berserker and turned into him, and his days in Sky Mist City had been rather fruitful over these days. His ambitions had also become increasingly savage.
In fact, he had even made the decision that once his power had grown stronger, he would devour Su Ming and turn into him to travel through the land. The reason for his ambitions was because he had obtained a sliver of memory regarding a particular inheritance when he was fusing with the Wings of the Moon. He did not tell Su Ming about this and had been training in secret.
These days, besides gaining battle achievements in the battlefield, he had used up all his other time to seal away the Wings of the Moon in his body. It caused Su Ming to be unable to use these creatures anymore because He Feng had turned them into one with him.
