The soldier didn't seem to want to deal with Gao Yang and showed no intention of answering Gao Yang's question. Despite this, Gao Yang didn't want to give up just like that; after a short wait, he awkwardly said, "So, um, where do you plan to go?"
The soldier turned his head away, still ignoring Gao Yang. If Gao Yang had any sense, the best thing would be to shut up and walk away. But Gao Yang was really obsessed at this point; he was determined not to stop until he got some answers.
After waiting a little longer, Gao Yang whispered, "Did you... kill someone?"
The soldier, who had been steadfastly ignoring Gao Yang, suddenly turned his head, staring at Gao Yang intently. But from his eyes, Gao Yang could tell he didn't intend to start a fight.
