Kapitel 2838: Unlucky

[They're saying hurry up and write ...]

Su Yun was playing with her phone while Zheng Ren was reading in the system library. At this moment, his phone rang.

"Hello?" Zheng Ren picked up the phone.

"Uh ... I'm still outside."

"Alright!"

After saying that, Zheng Ren suddenly stood up.

"What's wrong?" Su Yun was a little confused.

"There's a table inside that's doing ERP and EST, but the guide wire is broken. They've been studying it in the operating theater for two hours, but they can't find a solution, so they want us to go in and take a look. " Zheng Ren said in a low voice.

He spoke in a very low voice. There were many people outside and no one knew that the patient's family was at home. It was the most basic thing to not cause trouble for others.

"ERCP stone extraction?" Su Yun hesitated for a moment, then said in disdain,"he must be too rash."

Zheng Ren shrugged. Then, the door opened, and professor Wu stuck his head out and waved at him.
