Whether this standard is accurate or not, no one can be sure.
But at least in the Qi Refinement Stage, it fits Luo Chen's judgment well.
As for the Foundation Establishment Stage, a further observation is needed.
That's why Luo Chen was not desperate.
The reason was simple.
Basically, all this was under the assumption of not taking into account the use of supplemental cultivation resources.
Like magical elixirs, spirit lands imbued with arrays, and even secret techniques and divine arts, etc.
These external cultivation resources can enhance the cultivation speed significantly.
This point was verified by Luo Chen during the Qi Refinement Stage.
"Two thousand years are nothing but an illusion. As long as I can continue to take elixirs, this timeframe would be drastically shortened."
"So, the only thing that troubles me is the elixir."
Luo Chen's eyes flickered.
What he was considering, naturally, was not about which elixir to take.
