A wave of dense "Breath" came out from the bottom of the passage and swept over Noah and the other two cultivators.
'Mausoleum? Is this some sort of inscribed room?'
Noah had lived in habitations with an enhanced density of "Breath", the capital of the Utra nation was filled with such buildings.
However, they were always tuned for cultivators in the human ranks, the most valuable ones were in the center of the city, near the Royal Mansion.
Generally speaking, a higher density of "Breath" quickened the cultivation speed but only in certain quantities.
Each rank of the dantian had a different purity of "Breath", cultivators in the first rank couldn't just absorb the "Breath" in rooms made for rank 3 cultivators, their dantian simply couldn't endure such a training speed.
That's why it was always better to have a slow but constant training rather than a fast and immediate one, putting too much stress on that organ would just produce injuries.
