Lin Qianxuan's cultivation speed was completely unlike the description, absurdly fast.
He was well aware that this was likely due to his unique physique.
After all, people are different from one another.
Given how long he had been settled, having something special was normal.
The subsequent cultivation of the first layer was not difficult, just continued cultivation, replenishing spiritual energy until the entire Qi vortex filled the Danzhong acupoint.
Lin Qianxuan sensed the spiritual energy around him; under his mental perception, the content seemed to be less than one-thousandth of the whole environment.
According to what Lin Qianxuan had read in books, normally, just sensing spiritual energy would take several days of visualization for an average person.
And the sensing would be very vague.
There was no way it could be as easily sensed as he did.
