Good kids should go to sleep.
Yu Dong's move was just as swift as Chen Ying's, she was once an officer who had to fight a mob of zombies, and yet she came out of that mobbing alive so what was a single Chen Ying? She immediately dodged the attack and even took Xiao Hua and Fang Chi with her making sure that the two of them were completely protected by her. Chen Ying wasn't a skilled fighter thus, Yu Dong only needed to smack her palm against Chen Ying's wrist using the latter's strength and pace to deviate the direction of her attack. Her hit was light but due to Chen Ying's uncontrollable speed, the latter stumbled back with a shocked expression on her face.
She expected Chen Ying to try and attack her again but Yu Dong seemed to have underestimated Chen Ying, who not only did not attack Yu Dong or Xiao Hua but instead she turned around and headed towards Li Hanjing who was still standing on the threshold.
