*Rumble!*
The sky answered his laughter with a low, menacing growl of thunder, but John didn't flinch. As he was thinking, talking to himself, and laughing, he developed an efficient harvesting way to activate the core and enhance it.
He adopted an approach to ensure he wouldn't end up slammed by a lightning bolt again. Every time he reached a corpse, he would first clear the fog using a Fog Seeker core.
Then, he'd extract the deep red Wrather core and throw it instantly twenty meters away to let it get activated by absorbing the fog, then baptised by the lightning at a safe distance. Once the strikes ceased, he'd dash out, grab the now-purple activated and enhanced core, consume it, and move on to the next.
At some point, he cleared enough fog around to stop using his Fog Seeker cores. The entire trap area was now cleared of fog, and all the monster remains were inside it. So, he simply worked and threw the cores he got around, further expanding the area.
