Not an Easy Clue

"Expert fecal detector! Holy sh*t!" Zhao Yu thought.

When Zhao Yu saw the public toilet, he was depressed and slapped Tycoon's butt indignantly. He reprimanded it, "Hey, I said look for people! People means people!"

"Woof! Woof…" Daheng leaped up half a meter in pain, yet he continued to bark at the public bathroom.

Although Zhao Yu knew Daheng very well, other detectives misunderstood Daheng's actions. They assumed that the criminal was hiding in the public bathroom, so they started surrounding it with their gun as Daheng kept barking!

"Hmm…" Zhao Yu failed to find a reason to stop them.

Finally, the detectives bolted into the men's and women's bathrooms. Unfortunately, there was an old lady in the women's restroom at that moment. Seeing a group of heavily armed policemen rushing in and pointing a gun at her, the old lady was shocked and almost fell into the toilet bowl.
