Gauging enemy strength

Rudra kept a close eye on Lucifer with his god's eyes as he realised that even with his exaggerated speed of flight due to his wings and his gravity manipulation, the devil was still faster and closing in the distance between himself and Rudra extremely fast. 

Just when Lucifer was about to catch upto Rudra and stab him in the back, Rudra quickly flipped mid-air and started flying backwards while facing lucifer as he had been taught by sariel. 

Lucifer unleashed a strong attack towards Rudra with his sword, however Rudra blocked it with the technique that Sariel had taught making a near 2-5° angle between his blade and Lucifer's giving the devil no chance to pressure Rudra backwards using his exaggerated power. 

SHING!!!
