Na Yun, due to treating Hawkeye, was directly killed by Wu You. Just as he had always guarded against Huang Dao and Na Yun, Wu You always had a backup plan. For him, in the movie world, the only person he could trust was himself, and other actors were tools to achieve his goals. Even if it meant the other person could have an extra life, it was only a tool that could be used twice.
At the same time that Hawkeye saw Na Yun fall, Huang Dao also noticed this. However, even though his skills were on standby, he did not use them. He believed that Wu You would absolutely not remain where he was. After being killed once in his dreams, Wu You had been meticulously armed to the teeth and would only act if necessary, otherwise, he would definitely not make a move.
