Arthur kept attacking the world until another change started to annoy him. It happened at world number two thousand and fifty-three where he didn't find any pillar in his eyes.
"Where is the pillar? Did they move it away?" he was surprised and this thought just popped up into his mind.
'Ding! No, the world contains the pillar,' the system said, 'Ding! I can feel it already.'
"Then where?"
'Ding! At the normal place.'
Arthur squinted his eyes again, yet he didn't see anything. "Are you sure?" he asked.
'Ding! Just go there and you'll find a dirty trick for them for sure.'
"But…" he glanced around before adding, "I have to clear this world first and that will take some time."
'Ding! You can leave them for later, just see what happened to the pillar.'
