I've Cultivated to Level 9,999, but the Outside World Is Only at Level 99

The Protagonist Seems Weak, but Is Actually Invincible

I've become indifferent to a lot of things,

Novels Where Qi Refining and Foundation Establishment Both Have 9,999 Levels

I remember a novel where the protagonist didn’t know Qi Refining had only ten levels, so he kept cultivating all the way to level 9,999 before breaking through to Foundation Establishment. Can anyone tell me the title?

I’ve Already Become a Nascent Soul Grandmaster, and You’re Telling Me This Is a Martial Arts World, System?

Any Stories Where the Protagonist Reaches 9,999,999 Layers of Body Tempering or Qi Refining?

The protagonist can't break through by body training, but keeps training anyway.

An Invincible Protagonist Who Thinks He Is Ordinary

The protagonist is invincible and knows nothing about cultivation. He raises chickens and dogs in his courtyard, all his belongings are divine artifacts, and all his pets are divine beasts. I've read two books like this, one with Li Yixi as the protagonist and one with Chen Pingfan. Does anyone know of any others? Please recommend some.
