Qin Shi Mingyue: Tian Xing Jiu Ge

Wuxia (武俠), which literally means "martial heroes", is a genre of Chinese fiction concerning the adventures of martial artists in ancient China.

The heroes in wuxia fiction typically do not serve a lord, wield military power, or belong to the aristocratic class. They often originate from the lower social classes of ancient Chinese society. A code of chivalry usually requires wuxia heroes to right and redress wrongs, fight for righteousness, remove oppressors, and bring retribution for past misdeeds. Chinese xia traditions can be compared to martial codes from other cultures, such as the Japanese samurai bushido.

In contrast to Xianxia, Wuxia stories are based on real-life martial arts and cultivation of qi, which lead characters to have extraordinary strength. Xianxia on the other hand, is more fantastical and characters cultivate through Taoist practices.

Note: It is difficult to categorize Wuxia and Xianxia without haven't experienced the show, so there's likely some overlap or ambiguity in this Stack.

List of donghua I watched/follow, mostly CGI, that have gotten a rating of 7-9 from me.

I have watched all of them and even re-watched some several times, I vouch for these if you're interested in cultivation, fantasy, adventure, reincarnation.
There are 49 CGI donghua in this stack, and 48 are good quality CGI of decent length per episode, while Yao Shen Ji isn't exactly good quality, it's a decent story and in my opinion fun to watch. Da Wang Rao Ming is the only 2d animation in this list, I love the story and characters, it's also very fun to watch.

I've seen a few interest stacks about this genre but I wasn't satisfied with their list so I wanted to do my own.
