Meaning of Left

Next to the screen in the corner of the study, there was a dark door with a password lock.

Cheng Lingfei had lost her pistol. Seeing that Zhao Yu and Miao Ying had broken free of the ropes, she opened the secret door without any hesitation and went in. Seeing Cheng Lingfei leave, A Yun and others had two people block the door. 

These people were good at fighting. Although Zhao Yu looked fierce to them, they believed that even if Zhao Yu and Miao were free, the two prisoners would not be able to defeat them

A Yun had particularly high self-esteem. Although he was young, he had previously received extremely rigorous professional training. Even a professional agent wouldn't be a match for him. He was sure that even if Zhao Yu and Miao Ying came at him together, they wouldn't stand a chance against him!

Therefore, after seeing Zhao Yu dodging his knife, he was the first to rush up to him and aim a kick straight at Zhao Yu.
