"Where did you think you're going? You're staying with me!"
The black lightning becomes more intense around Rex's body, he looks at Miru coldly, "Flash!!"
SWOOSH!!
Rex's body disappeared from the spot leaving sparks of black lightning,
He uses his newly acquired skill from the system that he just learned, it is a utility skill that increased his speed briefly.
In a blink of an eye, he turns into sparks of black lightning.
Then suddenly, he appeared beside Miru just a couple of inches from grabbing her neck.
One has to know that Miru is a speed specialist based on her high agility stats, although she is hurt, she's still a fast Elementalist.
'Eh?", she looks to her back and saw Rex right behind her back.
Miru widened her eyes in surprise, she didn't expect Rex can be this fast based on the fight they had before where Rex barely catch up to her.
