The Netherworld Emperor was meditating to the side, frantically striking the barrier again and again. Ripples of Spiritual Power emanated from him, wave after wave, letting Yi Tianyun feel the terrifying nature of this power.
Once the Netherworld Emperor broke through, he would reach an unprecedented realm and possess the immense power to crush everything.
Although breaking through to the Spirit King Stage was incredibly difficult, it wasn't impossible. The Netherworld Emperor's talent was astonishing, and after cultivating for so long, a breakthrough was certainly within his reach. The fact that he was now frantically striking the barrier in an attempt to break through was the best proof of all.
'Looks like I'd better stop him, and fast.'
