Chen Tang opened the marriage document in Xuan Wanzhu's hand, which was quite similar to the ancient Huaya marriage document format.
It included the eight characters of birth of both parties, along with many other detailed items!
Most crucially, the marriage document bore the signature of Chen Tang's grandfather and the cipher of the Chen Family Clan.
Therefore, it seemed that this marriage document couldn't be fake.
Moreover, Chen Tang had gathered some information from conversations with people like Chen Hong and Xiao Yang, that when Ancestor Chen was alive, he seemed to have dominated the entire Huaya, imposingly setting marriage agreements with many families within the Yuanwu Noble Family.
It was presumably a precaution to prevent the Chen Family from falling into decline, leaving a contingency for the Chen Family Clan—Chen Hong was indeed chosen by the young lady of the Xiao Family.
