L99. Seeking Sentries (REP)

"There are many rumors in Rebel recently. One of them was caught by a ghost."

"I heard the soldiers on guard say that during the night, something would trip their feet, causing them fall down." After they picked themselves up, they saw nothing around them."

"But who could catch people without being discovered? After thinking, I guess it's the mischief of the Kappa and jellyfish. Could you help me drive them away from the Rebel Camp?"

"So is it really their tricks?"

"Oh, it is! Thanks for your help."

"I'll declare the news to everybody. They won't need to be afraid."
