Xia ruofei's brain was working at full speed. He had to kill at least six puppets in the short amount of time left. These puppets were all moving. Especially after he successfully attacked three puppets, the other puppets 'speed suddenly increased a lot and they were all rushing towards the location of the attack.
Xia ruofei had to take some risks. He had to take advantage of this time to attack from the side and try to kill a few more puppets. Otherwise, he would not have enough time when the commotion died down.
Furthermore, Xia ruofei knew that the original infant stage puppet would soon realize that the painting was missing. By then, he did not know what would happen.
Hence, Xia ruofei's strategy became more aggressive. He did not wait patiently for the right moment like before. Instead, he went to meet the three puppets who were coming in a group.
