Huang Zicheng struggled helplessly in the waves.Yao Yao came to Jinhai Hospital and took the injections placed in the hospital storage cabinet according to the message sent by Spy Game.Gao Tianyang deliberately diverted the nurse's attention. Yao Yao took advantage of Xiao Yi being sent for examination to sneak into the ward and hide in the closet, waiting for an opportunity to act.Wu Xi had been unable to contact Huang Zicheng, so he had to go to Gao Tianyang to inquire about Huang Zicheng's whereabouts.At this time, Gao Tianyang was outside the ward, trying to distract his colleagues who were guarding him.Yao Yao came out of the closet and injected the prepared injection into Xiao Yi's body.Soon Xiao Yi's electrocardiogram monitor sounded a piercing alarm. After emergency rescue, the doctor reluctantly declared Xiao Yi dead. Yao Yao took advantage of the chaos and left the ward among the nurses.At the same time, in the hospital corridor, Jiahui pretended to be a patient and was secretly observing everything happening here.Gao Tianyang also noticed this mysterious female patient and followed him all the way, but was thrown away by Jiahui.Wu Xi hurried to the hospital and learned about Xiao Yi's death.
