In the Upper Realm, a force suddenly pierced a corner of Central Wutu Eight Hundred Li Sifang City from below, causing Primordial Qi to pour into the lower realm and immediately alarming the nearby Qi Refiners.
Hundreds of Qi Refiners gathered at the site of the Heavenly Leak, only to discover that it was not merely the foundation of Sifang City that had been pierced.
