Luck

Ryu had yet to meditate upon the Lightning Inheritance of the Lightning Qilin Clan. The truth was that the moment he awakened their Spirit Body Talent, his body was reconstructed into the Yang Lightning element. As a result, he could use lightning qi at will without having comprehended an Inheritance. 

Due to the fact he still had poor control of it, whenever his qi surged, streaks of lightning would unconsciously emanate from his body, striking the surroundings with a vicious momentum. But, it was exactly this uncontrolled lightning that shook those watching on. 

It was too powerful!

The streaks of beautiful blue lightning beneath Ryu's feet were even more devastating than his surging spear qi, directly causing savage cobwebs of cracks to race across the ground. If it wasn't for the fact that the precious materials that formed this tower were already black, it wouldn't be hard to imagine that they would have been charred as well.
