Lin Jian decided to ask, "Impulsive?"
Yao Ying nodded. "Yes. I saw how this mission affects your emotions. You can't make a good judgment without a cool head. We also want to save her, but we don't want to risk war between the countries. Do you understand me?" Yao Ying decided to say what's on his mind in advance. He needed to make Lin Jian see his shortcomings.
War involved a lot of parties and the one who would be sacrificed was the commoners. Yao Ying and Yao Ling knew how they didn't care about political matters --- they just wanted to live in peace, just like how they used to be. They didn't want Lin Jian to be blinded by his feeling and ruined the current peaceful era.
What Yao Ying said really slapped Lin Jian's face. He realized that he was being too hot-headed and too selfish. He closed his eyes, trying to calm himself down. Once Lin Jian opened his eyes, Yao Ying asked him, "Do you feel better now?"
