For example, the Ji family.
Xie Yun, the daughter of the main Xie family, married Ji Lingfeng.
The other daughter of the Xie family, Xie Tingyun, was married to another family among the three major forces, the Nan family.
Moreover, the difference between them was that other than marrying well, Xie Yun did not have any other ability. She was more like a rich and idle wife.
Xie Tingyun was an expert in smelting when she was young.
Don't think that smelting sounds a little simple.
It is actually a very powerful skill. The raw materials for the truly powerful weapons in the world now involved smelting technology.
The more sophisticated a weapon was, the more it involved manual manufacturing.
However, Xie Tingyun could be called a master in this aspect.
