Tbh, I think if you read an mxtx novel with the expectation that the story’s hero is meant to learn some valuable lesson that fundamentally changes their character and views on life, then you are reading her books wrong. There’s not a single mxtx protag (currently) in existence who changes by the end of the story. It’s the world they live in that is changed because of their actions:
—Shen Yuan’s Shen Qingqiu transforms a toxic masculinity fantasy into a queer romance in which the unhappy stallion protagonist with a harem in the 100s is given his monogamous happy ending with a husband he actually loves and values with reciprocity. They fuck off to their forever honeymoon after exposing the corruptness of the cultivation world that ruined Luo Binghe’s life to begin with, and all of this was only possibly because Shen Yuan was just a genuinely nice fucking person. The world lives to see another day and a fuckton of people who died (or didn’t even get to exist) in the original stallion novel get to live long, more fulfilled lives in Shen Yuan’s revision.
—Wei Wuxian is killed for sticking up for a condemned clan, is resurrected against his will, and still stands by his actions in his first life while protecting those that continued to wrongfully condemn him. As a reward, the corpses of the people he died protecting save him and his loved ones (and the rest of the bystanders who killed them), he bags himself the most perfect and perfectly matched man in the cultivation world, and he continues to help others and do what he wants to the ire of the cultivation world who are now too embarrassed to fight him. The younger generation look to him as a beloved teacher, protector, and role model to aspire towards.
—Xie Lian rebelled against hierarchy as a beloved prince of a prospering kingdom, then as a beloved god against the older gods, then as a reviled scrap gods against the then most popular gods of the present day. He was always willing to lend a hand to anyone who needed it and to never hold resentment even if that kindness blew up in his face (and it often did). He gets to marry the man (ghost) who has seen him at his best and absolute worst and chooses him unconditionally, something no one else has ever done before. At the end of the novel, he is the god that all the other gods look to for guidance and strength.
None of these stories humble these characters for being good people. Even when their morally righteous actions net them unimaginably terrible results, even when they falter in the face of their failures, they ultimately remain true to their goodness. And none of the books humble them for that, because being good is not a character flaw. So in short: please stop talking about how mxtx protags “needed” to learn valuable lessons to “be good people” when they were already good people from the very beginning. These stories are not about how the world changes people but how genuinely good people can change the world just by actively being kind even with no benefit to themselves and especially if that kindness leads to detriment.
