Recommendations unorthodox cultivation system

I'm looking for an unorthodox cultivation system, or where the mc finds a totally new or before unseen way to cultivate.
like Empire of salt.

 

Tales of Herding Gods, people cultivating by "borrowing" deities' power, each step has its own deities.

 

Renevald Insanity.

They use Gu or insects for cultivation.

 

Soul of Negary - while others rely on their True Spirit, mc uses his soul to get stronger.
Divine Throne of Primordial Blood - humans that can cultivate have to rely on bloodlines, mc who doesn't have a bloodline creates his own way.
The Dark King - the whole cultivation system in this novel is quite unique.
Legend of the great sage - cultivates both human and beast cultivation.

 

I must agree The Dark King does indeed have a unique cultivation system and is actually very good.

 

silent crown - has a music-based cultivation and fighting system. makes connections with lots of famous historical pieces and composers
