With a loud boom, Ning Cheng's entire body suddenly relaxed in an instant, as the liquefied True Yuan found its vent. The meridians and acupoints in his body released a series of crisp sounds, and with each sound, he felt lighter.
He was overwhelmed by an unprecedented sense of joy and an indescribable epiphany. Ning Cheng couldn't help himself and, just like Yue Ying, let out a continuous and long howl. The immense power brought Ning Cheng an inexpressible elation, and at this moment, he couldn't care less about the impurities seeping from all over his body.
Ning Cheng knew that he had finally succeeded in reaching the Building Foundation Realm. It took four Upper-Grade spiritual stones to achieve this success. The true divide between cultivators was the success of Building Foundation; only then could he claim the qualification of being a cultivator. Only now had he truly laid the foundation of his own cultivation.
