Time slowly passed and, before even the couple succumbed to the cannon shot called 'Bio Blaster', the rest of the inhabitants of the world, those who weren't dragged away by the System's teleportation, died in five seconds or less.
The trees withered, rivers dried, and the small organisms vanished from existence, killed by the toxic attack launched by the System.
In five minutes, the world didn't resemble its former peacefulness and became a barren land full of death and eerie emptiness.
Arthur and Lucy laid next to each other, both unconscious for a prolonged period of time as the System refrained from dispatching any robot to retrieve them until the effect of the blast lessens a bit and becomes non-lethal.
One day passed and the first to somewhat wake-up was Arthur, who had a lot of difficulty breathing, much less properly moving, nevertheless, he tried his best to sit-up and move a bit closer to Lucy, checking if she's still alive or not.
