Okay can we just appreciate how each brother has a distinct voice here without any exposition? The author doesn't tell us who's the serious one or who's the soft one—we just KNOW from how they speak.
Jiang Xun is the practical one: "I'll go tell them we're refusing." Straight to the point. No nonsense.
Qin Shuo is the strategist: "Or we could agree for now. Our precious girl never goes outside anyway, so they won't see her." Thinking three steps ahead, finding loopholes.
Nan Qi is the protective big brother through and through: he's the one who physically shields Li Tong, who carries her, who coaxes her. His dialogue is full of softness even when he's frowning and worrying.
And Xiong Ji—apparently the leader, the one they all look to—speaks last, after the longest silence, with that quiet sigh. His voice carries weight without raising.
The dialogue with Li Tong is where it really shines though. Her brothers don't talk down to her. They don't treat her like a child even though she clearly is one in their eyes. "What's wrong, Little Treasure?" "Why's your little mouth all puffed out?" They use pet names naturally, the way real siblings do. And her silence speaks volumes—she doesn't need to explain herself. They already know something's wrong just from her expression.
The mercenaries outside also get distinct voices, even though they're background characters. Their desperation comes through in lines like "For the sake of the days we fought side by side, give us a chance to live." You can hear the pleading, the history, the genuine bond beneath the intrusion.
The narrative voice itself is also worth mentioning—it's warm, observant, almost omniscient in its understanding of these characters' motivations without ever feeling intrusive. It knows what everyone's thinking and still lets them surprise you.
