天地缓缓 In this world, indefinitely [eng sub]

"天地缓缓 In this world, indefinitely [eng sub] – 魔道祖师 Grandmaster of Demonic Cultivation" (Watch on YouTube)

This one is technically not a fansong, but the drawings are nice and the closest thing to a happy ending these two seem to get, and the song is super soothing. It is also now my voice headcanon for Song Lan!

Music: 天地缓缓 by 伦桑 (an actual non-fansong)
Drawings & original video: __円 on bilibili

Thanks to yjtc from the Nirvana in Fire Discord/fwoopersongs for helping me with my translation questions! Any mistakes that remain are entirely mine. The Zhuangzi, also called 南华真经 (Divine Classic of the South) is an ancient Chinese text from the late Warring States period which contains stories and anecdotes that exemplify the carefree nature of the ideal Daoist sage. One theme is accepting death as a natural transformation, which Song Lan doesn't want to do.
