Eventually, Lin Mengmeng's Mental Strength level finally broke through to the 12th grade lower-class level.
Because Xia Qingqing had used the remaining Heaven and Earth Divine Hearts on Lin Mengmeng, Lin Mengmeng's Mental Strength was already close to the 12th grade lower-class level and had definitively broken through to it now.
With this, the purchase of these Heaven and Earth Divine Hearts was truly worthwhile, allowing both of them to break through to the 12th grade lower-class realm, thereby almost returning the value of nearly tens of millions of Spirit Crystals.
With a breakthrough in Mental Strength to the 12th grade lower-class level, Lin Mengmeng's strength greatly increased.
Her Martial Arts Realm, which was only at the initial stage of the 11th grade, now possessed the strength comparable to that of a late-stage 11th-grade cultivator.
At such a high realm of the 11th grade and having such strong cross-grade abilities were indeed very rare.
