Yan Yu was completely baffled.
Body Tempering is such a difficult affair, and as a Flame Guard, she knows this all too well.
Actually, cultivators who reach a certain realm are already aware of their own physical shortcomings, but—how hard is it to temper your body?!
The body isn't like your realm; with enough time, with understanding, you can improve that.
The strength of the flesh is extremely difficult to enhance, and the time needed is extremely long.
Even so, Yan Yu had never heard of any cultivators in the Immortal Country who could strengthen their flesh to Foundation Establishment level.
That seems to be a barrier.
Almost no cultivator can overcome it.
But Qin Yu's body is more than just Foundation Establishment level…
Yan Yu instinctively squeezed Qin Yu's muscles with her hand.
This…
It's actually reached Golden Core Peak!
How could anyone temper their flesh to Golden Core level?!
