Illusive Army

Finally, our main problem. This jinn kept asking if we had any enemies... Really, what enemies can we have besides laziness, ignorance, and idleness? But my friend suddenly says, "Second pioneer group are our enemies, and we want to beat them in the competition."
But the jinn is dense, he doesn't understand today's world. He created an illusive army. What do we need an army for? We let them all go.
But they wandered into the city and started terrorizing citizens. They are ancient and thick! Please deal with them: they are just illusions, not real warriors.

I await good news, though I understand the task is not easy.

Great, it should be quiet in the city now!
We heard you're looking for information on what happened at the construction site? I'm sorry I can't help you. They promised we'd go on an excursion to the site, but it never happened. None of the pioneers were at the site.
