To be honest, Yu Ziqing didn't come this time to stir things up.
He just couldn't immediately ask about the long-missing Chu Ye, as Song didn't have that intelligence.
When the Emperor Qian wasn't in seclusion, Song at most did a small favor for Cheng Jing by providing a bit of intelligence.
Privately placing personnel or secretly probing into information within the Langya Institute, Song definitely wouldn't have done that.
Let alone obtaining detailed information about a current dean.
Talking with the Dragon Tiger Daoist, he could only casually chat about some important matters. Seeing the Dragon Tiger Daoist's reaction being even greater than expected, he quickly changed the subject, bringing up Chu Ye.
Chu Ye obviously hadn't given up on finding out the truth about past events, and most likely, someone was watching him.
If you genuinely want to find out something but can't, and can't confirm it, trailing behind Chu Ye and letting him do it is clearly the best strategy.
