What did I offend?

"Wu Wu Wu ..." This time, bureau chief Abu Ajie nodded hard and said in not-so-fluent English,"I ... I'm just following orders. I know ... You're from China, and one of you is a famous detective!"

Hearing this, Zhao Yu and Ding Lan looked at each other. Zhao Yu nodded proudly. It seemed that they had not wasted their efforts, and had found the right person.

"Alright then, whose orders are you following?" Zhao Yu asked again,"why did you frame us? When did we offend you?"

"I ... I really don't know!" Abu Ajie said with an innocent face,"the order I received came from the upper house. Someone suspects that you're a spy carrying out sabotaging activities. They want US police to find an excuse to arrest you first and then interrogate you!"

"F * ck!" Zhao Yu grinned, then asked,"the upper house should have a name, right? Who gave you the order?"
