Simon had been completely focused on his battle, and his injuries had further narrowed down his perception, but he felt quite sure that no new threats had appeared.
Of course, cloaking techniques existed. The brown-haired woman had used one, too, to ambush Simon with her fireball.
However, trying to hide a destructive rank 2 spell made sense. Instead, a mere ordinary arrow didn't.
Still, before Simon could push through his scorching pain to make the point of the situation, something else invaded him. His right foot went numb, and the sensation rose toward his knee, seemingly wanting to take his whole leg out of commission.
Simon had no real defenses against that. Whatever had infected him also seemed to worsen his mind's already poor condition. But his Qi was fighting that invasion, so he focused on his circulation technique.
But another arrow arrived before Simon could forcefully circulate his Qi, hitting his left heel now in the same spot.
