Chapter 563: Mutation!

Johnny immediately turned around, and to his shock, Captain Casey had already appeared in front of him, throwing a punch at him.

Johnny instinctively threw a punch at Captain Casey but didn't anticipate that Captain Casey's punch would accelerate suddenly, hitting him before he could land his own.

Bang!

Even though Johnny was all muscle, the punch still felt like it shattered all his insides, causing him to spurt out a mouthful of blood: "Puh—"

"Damn it, it's the red genetic drug kicking in!" Seeing the dire situation, Johnny turned to run, but how could Captain Casey possibly let him go?

Johnny was already fast, but Captain Casey was even faster.

He had only managed to run out a dozen meters or so when Captain Casey caught up to him and landed another ferocious punch on his back.

Johnny rolled on the spot to dodge Captain Casey's punch.

Captain Casey quickly followed up, her five fingers transforming into claws and shooting straight for Johnny's heart.
