The Ruyi Yin Thunder, cultivated by Shi Pi the Elder, was also a nuclear weapon-level Magical Treasure. Its basic damage was capable of annihilating all living beings within a thousand miles, sparing neither immortals nor mortals!
During its activation, one could use their own True Qi to enhance the explosive power of the treasure, the greater the effort, the larger the killing range and the greater the lethality.
With Shi Pi the Elder's mana acquired from over a thousand years of cultivation, if he were to launch it at full strength, risking his own life, he could at least expand the Death Forbidden Zone to a radius of five thousand miles, affecting areas up to ten thousand miles away.
He had recently made a breakthrough in the Demon Path, experiencing the Five Yin Flames intensively, causing his mana to surge explosively.
