These are both BL Chinese fantasy shows. The main pairing has a similar feel in how only one is mortal and seems icy at first, while the other is a supernatural being who comes off more innocent and childish. The relationship starts off on a bad foot but they quickly soften towards each other.
Ling Qi is set in a more modern world with magic. In contrast, Tian Bao Fuyao Lu is in a fully fantasy setting in another world.
Tian Bao Fuyao Lu (despite being cgi) has much better art if that is important to you. However, season 2 of Ling Qi does look better
if you can hold out.
Both are recommended if you are looking for BL in a fantasy setting with relationships between humans/supernatural.
