You would be right based on the drama and spoilers I've read. I am loving the references to GTY's military deeds in Chapter 104. You can see why he became powerful in such a short space of time. War really was a time of opportunity for those who wanted to advance themselves. Minglan marrying GTY would have provided strong connections for the Sheng family. For those keeping an eye on references to Ming Lan"s age as I do, note in Chapter 104 it's mentioned she's a few months shy of 15.
