Absolutely terrible (1)

Zheng Ren ran all the way upstairs. When he arrived outside the private room, he stopped in his tracks and adjusted his breathing and expression.

This was the most important moment, and he couldn't afford to be careless! Zheng Ren thought to himself and cheered himself on.

It would work, it would definitely work!

If he was too nervous, he might as well hide in the system's operating theater and calm down.

He still had a trump card. It was fine, it was fine.

Zheng Ren had never expected that the system's surgery training time could be used in such a way. This was an idea that came to him on a whim, so there was nothing inappropriate about it.

"Dang dang dang~" Zheng Ren knocked on the door.

As his fingers knocked on the door, his heart began to beat faster, as if he was going to participate in an emergency rescue.

There were sounds coming from inside the room. Someone was talking.
