If breaking limits were so easy, they wouldn't be called limits.
Unless one's realm cannot be broken, a Martial Cultivator will choose to break through limits.
Some geniuses also slow down their breakthrough speed voluntarily to deepen their foundation, solidifying every level.
Solidifying one's realm doesn't mean Body Refinement, but cultivating one's Cultivation Technique to the limit, elevating Spiritual Power to the limit, and raising Qi Blood to the limit, breaking through only when there's no further path.
Accumulating realm by realm, the difference between late-stage cultivators and ordinary Martial Cultivators is nothing short of worlds apart.
Lu Yu's powerful physique can contain Spiritual Power far exceeding his current realm; theoretically, he could hold tens of thousands of Spiritual Power.
However, merely increasing the amount of Spiritual Power without elevating the realm will not improve the quality of Spiritual Power.
