What was weird in the eyes of many masters was the lack of any monster. Many thought monsters got terrified of such a gathering of humans, and others thought this was the act of dark masters. William knew both were correct. And he didn't care about fighting any monsters during their travels.
The distance between them and the Black Holes region would take one month normally to travel. During which, more masters kept joining them, as many grew impatient and moved to station themselves at the border of this region.
They were the type to seek adrenaline in life, the type that William liked the most. Totally opposite to them, there were many masters who loved playing it safe, and waited for the grand army to move, even moving at the rear end of the grand armies.
William didn't interfere in anything, simply walking towards his destination while thinking about the Black Holes zone. He also was concerned about his enemy back in his world, the Nightmare monster.
