Originally, Qin Yu did not intend to know much about the Ning family's company because it had nothing to do with her. After all, she owned Glory World, and at most, it had some collaboration with Tiankun. The affairs of the Ning family wasn't something she'd want to get involved in.
However, after going to Guan family's banquet last time, Qin Yu suddenly realized that the Ning family's affairs might not have had anything to do with her in the past, but it might not be the case in the future.
She found relevant information and began to study the hundred years' history of the Ning family since their rise.
She also had a rough understanding of the families that were not directly related to Ning Chen.
Ning Chen had probably seen these things many times before. His parents had died in an accident, so he must have searched through everything that he could, so Qin Yu actually did not expect to find anything that Ning Chen had not found.
