Rokuya stood up, walked over to the lab bench, and looked at the red blood samples.
"Once the explosion happens and Muzan is wounded, he will never choose to expose himself to sunlight. He will open the gates of the Infinity Castle and drag every Hashira and Demon Slayer Corps swordsman nearby into that alternate dimension.
