Hiss hiss hiss...
There was a ringing noise from within his body. His body, forged through pain and struggle, was trembling uncontrollably. For the first time, Casio felt the shadow of death looming over him.
Unlike the previous times, he was crushed completely. A single fist shattered his highly robust defensive stance, making the whole process seem simplified.
There was no back and forth. Either one could take the blow, or they couldn't. It was brutally straightforward.
He, Feng Liusi, and Sheng Feinan, could hardly withstand ten strikes from him. A realization dawned upon Casio.
Supporting his body, the echo strength inside him finally broke free and exploded. A force resembling a shock wave was swelling within in his fragile body, going through his muscles, bones, internal organs, and arteries, like a sieve, eventually all rushing to his skin.
Bang!
