The blade of light was two kilometres long, swung with all his might. The momentum its bladed tip carried was tremendous as it slashed towards its target.
"It's been awhile…Light." A tentacle rose from within the water, morphing into a human hand, but giant-sized. Faint bluish-white light converged on its surface as the blade came into contact with it. The sound of the explosion created a powerful sonic boom that pushed away the surrounding Skeps, the water forming a wave as the area of contact was bereft of it.
A massive tide was created as a result; the water gushed into the vacancy only after more than ten seconds had passed. Such was the power held within the blade's swing. The hand that caught the blade though, was mostly unharmed, only sporting a cut that healed within a couple of seconds.
