But the black page didn't crash. Instead, a new line of code appeared at the bottom, typed by something that wasn’t Leo:
One by one, the student dragons started slowing down. Maya’s gold dragon turned gray. Kevin’s green dragon got a pop-up: [This game violates school policy. Please return to learning.]
But today was different. Today, Leo had a secret.
Leo knew the drill. At exactly 2:47 PM, Mr. Henderson’s network monitoring software would sweep through the school’s Chromebooks like a digital janitor, locking down anything that smelled of fun. [Cool Math Games] would become a gray wall of shame. [Shell Shockers] would scramble into an error message. By 2:50, the only thing left would be the school’s dull library portal.
They were hooked. Within ninety seconds, a crowd had gathered around Leo’s desk. Someone from the back shouted, “Make it two players!” Another yelled, “Add power-ups!”
Leo didn’t panic. He looked at the cursor and thought: What would be so fun that even a firewall couldn’t resist?
IRON_WALL breathes a cloud of “Access Denied.”
