81 How Did you Know About Our Operation?

This female killer codenamed Dolphin didn't leave after putting down the food. Instead, she directly went to the washroom and changed into a nurse uniform. When she came out again, the two nurses on call were both rushing to go to the toilet. She immediately slipped past them, pushing the cart with the needles and syringes and walking towards Xu Cheng's ward. 

She said to her earpiece, "I'm approaching the target and will euthanize him."

Central communication: "Very good, I will get Brother Iron to come up for reinforcement. The moment you succeed, he will lead you to leave the hospital as quickly as possible. Remember, don't leave behind any evidence."

"Understood," Dolphin said. She put on transparent gloves to prevent herself from leaving any fingerprints for the police to pick up.

When she pushed open the door to Xu Cheng's ward and went in, she found that Xu Cheng was staring right at her with an unblinking gaze.
