Actually, Jin Yong's stories are often about meshing fiction with historical events and characters, e.g. Genghis Khan, Zhu Yuanzhang, Wu Sangui, etc. The settings often deal with a larger historical context, such as the rise and fall of dynasties. I highly doubt whatever "generic trash" you have in mind have any such historical significance.
Furthermore, this particular story is about as far from "generic" wuxia as you can get. The protagonist can barely fight! Compare it to all the Mary Sues you see in more recent stories...
Some comments seem to be coming from people who never even bother to read. "Beauties for cultivating tools..."? The "cauldron" doesn't even have that meaning here. And his harem is only secondary to the main plot. You won't even see the first girl until Chapter 54, unlike those isekai harems where the interchangeable girls literally beg to be the MC's slaves a short while after meeting the MC...
