Potato Salad

Time ticked by, little by little.

Chief Qi performed the ultrasound while asking about the history and evolution of the disease.

It was obvious that the patient had a history of cholecystitis, and the position of pain that the old man had described matched. The ultrasound probe pressed on the Murphy's sign. There was tenderness, but there was no rebound tenderness or muscle guarding.

But...

The ultrasound showed that there was nothing wrong with the gallbladder!

Chief Qi checked it bit by bit, afraid that he would miss a single frame of the image.

Ten minutes... 

Fifteen minutes... 

Thirty minutes...

The ultrasound took half an hour.

Chief Qi suddenly asked, "Comrade Zheng Ren, Comrade Su Yun, do you see the problem?"

"No," Zheng Ren said honestly. "I don't think there is a problem."

Hearing Zheng Ren say this, Chief Qi's hand froze for a moment. The probe in his hand was as heavy as a thousand tons.
