Conductivity

While everybody was staring at him, Electrician Wu's face turned completely red.

Even if he faked an electric shock, it would not work…　　

"That's strange. What's going on? It was leaking electricity yesterday at home…" He was doubtful as he bent down and looked at the heating rod through the glass of the tank.　　

The heating rod stayed at the bottom of the tank. The orange light was on, indicating it was working properly. 　　

Switching the rod was impossible. The store owner picked up the heating rod and inspected it, but Electrician Wu was keeping his eyes steadily on it. The owner could not have possibly made a switch in front of his eyes, unless he was a part-time magician.　　

"There… There was, indeed, an electricity leakage at home…" he mumbled to Snowy, wanting to prove that he was not lying.　　

Snowy had nothing else to say.　　

She had already chosen to believe that Electrician Wu's heating rod was leaking electricity. Could he have wronged the store owner?
