Brother Shiguang had been watching continuously for two days, still waiting in vain for Beisitian and the others to return. Realizing that something was amiss, it was either that Beisitian and the others hadn't noticed the mark he left or the mark itself had some issue.
With the aunt's cleverness, it was unlikely she wouldn't notice in such a small room, so it was mostly the second possibility.
If that's the case, it explains everything; he must be under surveillance by those people.
Brother Shiguang planned to have no interaction with Luo Yirui. Yesterday, he went to the small courtyard late at night, found Brother Tian Zhi guarding the side room, and explained the situation to him.
Brother Tian Zhi said to let him continue as he is now. Brother Shiguang couldn't help with much anyway; delivering the message was enough to complete the task.
