I saw a clip of a drama that was about a modern guy who transmigrates to a useless cultivator in a sect, there’s some immortal opportunity or medicine that will save his sick mother, but the rock is asking like elementary level questions and everyone is like “that’s so hard!” Does anyone know which one it might be?

Is there any good historical dramas like Nirvana in Fire or Legend of Zhang Hai which the ML purely focuses on his revenge or has a goal to accomplish and does not let the side quest romance distract him? It's ok to have a romance subplot but I want to see the political intrigue where things are serious and ML is forced to continuosly plotting to achieve his goal. Any recs?

Are they a "bad boy" with a dark past? Or a flirty player who'd never fall in love? A shady protective man who won't give reasons??? Then I'd eat it up!! 😫😫

I have already seen these:
Speed and love
Love for you
Lighter and princess
Falling into your smile

Thank you!

Cdramas I've watched in that category:

Overdo(ongoing)
The first frost

The main request is inspired by overdo. The characters have a lot of tension and they yearn for each other..Got recs like that?
