"Go on, you're off work now, and I'm on leave, so whatever you're doing has nothing to do with me." Yao Ke said generously, gesturing for his two subordinates to relax.
Li Juntao immediately felt his tongue tied, unable to defend himself, but he had to say something to clear things up: "Yao Ke, Professor Yan got drunk at the bar herself, and a waiter there randomly called for help, and it ended up coming to me—"
This is exactly what "there are no 300 taels of silver buried here" refers to, Li Juntao's words.
Yao Ke genuinely admired the new guy, Li Mutou, considering him hopeless. Saying this in front of a lady, and what's more, his female superior, was no different from digging his own grave. If he were tall and handsome, he'd surely still complain, but he'd definitely avoid saying it in front of Witch Yan.
Witch Yan has a strong sense of revenge.
