Rudra rushed towards Vigo and due to the time dilation his speed was beyond exaggerated.
Rudra's speed was basically so fast when using this skill that he was travelling faster than the speed of sound which created a sonic boom when each of his muscles moved.
Although Rudra himself did not realise it , for his body to become tough enough to sustain such speeds it was only possible because he was no longer technically a normal human, otherwise even if he was a tier 5 individual with this speed using the skill would do his body self harm at this pace.
A normal human could only accelerate X5 without his bones crumpling due to acceleration however Rudra did not feel anything even at X10 speed.
This was testimony to him becoming more than what a normal human was destined to be as while he himself did not understand the implications of his own power the intense battles and constant struggle were honing his skills naturally.
