The fact that An Yue was the daughter of Nie Xingzhi, the second-in-charge of the Nie family, was deliberately concealed by the Nie family and Zhao family just like how Duan Yarong and the others did not want outsiders to know that An Yue was pregnant.
Nie Xingzhi did not have any objections to this. For him, An Yue's willingness to acknowledge him was the best news, even though he wanted to announce to the world that he had found his long-lost precious daughter.
However, An Yue's current priority was to rest and recuperate properly. She was going to give birth to a big baby for the Zhao and Nie families in a few months' time. Unnecessary matters would only bring unnecessary troubles to her. This was not what Nie Xingzhi wanted.
Anyway, she had already acknowledged him. He could die a happy man. The family could announce it whenever they wanted to. There was no rush at the moment. At that point, the other adults had the same thoughts.
