Recommendations Modern MC reborn in cultivation world(from birth ,no game elements)

Novels with MC reborn in cultivation world (Xianxia like). Specifically :

• MC not from a world which gives him/her a power to substitute cultivating with , he/she has to cultivate
  
• MC reborn from birth , not transmigrated into some existing person ( eg waste young master/concubine or dead person)
• No system, game like leveling up

so far the only novel I've come across that's similar is "My Senior Brother is Too Steady", but that too the world is based on chinese mythology so mc knows stuff that's supposed to happen

 

Omnipotent Sage

 

Okay, for this recommendation I have to explain a little bit. It's also a spoiler.

Spoiler

The MC thinks he transmigrated into a young master. That happened as he was very young. Maybe 5-10 years old? The novel doesn't specify the age, but he was actually reborn from modern times into the cultivation world.

"I am the young master"

This is an original novel on webnovel. It matches your criteria perfectly, even

 

Desolate Era, The Magus Era, 'Crossing to the Future, it’s Not Easy to Be a Man'...
