Chapter 287: Qin Clan's Old Ancestor!

Bei Feng continued examining the wing with interest. This was something he had not expected. Initially, he thought that the Celestial Snow Ridge Eagle Wing was a treasure with a fixed grade, and it would not be able to improve. However, it had actually risen a grade after being infused with large amounts of blood and Qi!

"No wonder it felt so smooth to break through to four times the speed of sound! Looks like it was the effect of that wind elemental ability!" Bei Feng mumbled. Previously, three times the speed of sound already caused him to feel as if he was flying through a sea of blades. But when he broke into four times the speed of sound, he instead felt like a fish in water!

Bei Feng lightly moved the wing, creating a miniature tornado in front of him. It spun about on the ground, tossing up large amounts of leaves and twigs into the air. But in terms of killing power, it should only be able to kill an ordinary human.
