Being a butler is not a job for just anyone.
Wu Hai had served as the butler in the Yang family for so many years, thoroughly familiar with everything about the family, although he was still somewhat unfamiliar with the situation in the Capital City, Lu Shou could complement his shortcomings in that regard.
Regarding why Wu Hai would wait outside the study for him, he understood that it was nothing more than the fear that Lu Shou might take over his position as the butler.
Yang Zhenshan was a person who valued old sentiments, so naturally, he would not dismiss Wu Hai from his position.
However, Wu Hai was not young anymore; he was fifty-six by now, and even if he continued to serve as the butler, he wouldn't be able to do so for many more years.
Whereas Lu Shou was not yet forty years old, when a few more years pass and Wu Hai retires, it would be perfect for Lu Shou to take over.
"Yes, this old servant will mentor Lu Shou well!" Wu Hai said with a chuckle.
