A recommendation blog for Mo Dao Zu Shi/CQL/The Untamed. mojoflower started this blog to post fanfiction recommendations and has since passed it on to other mods as the blog has grown extremely large and popular. I believe most if not all of the fics recced are located on AO3.

Art Blogs [These are blogs where the artists regularly post their work]

Pomrania often does art challenges where they request people to share pets with them and they create transformative artwork of the pets shared with them. They also do some impressive and adorable crochet.
