After what happened with the Immortal Ascension Pagoda, the Yu Family was completely defeated.
After the pagoda broke open, Yin Qi continually flowed out, frightening everyone. Nobody thought an Immortal Pagoda which linked directly to the Immortal World would be filled with so much Yin Qi. The entire Huayuan City was affected as a result - the Yin Qi did not dissipate even after several months and the spirit Qi remained scarce. The cultivators left the city in groups. Nobody dared to even come near Huayuan City unnecessarily. Far from being the important central town, Huayuan City was just a dead town now.
