Once Mo Wuji stepped out of Nirvana Resthouse, he could sense a sort of rotting and corrosive aura. This sort of aura was almost the same as what he felt coming from the curse seal of Gods Precipice Continent. It seemed like Kun Yun wasn't lying. This was really Curse Arts.
The cultivators on the streets had fear in their eyes, and many of the people that just entered the god city wanted to leave again. As all transfer arrays in the city were shut down, one had to fly off if one wanted to leave. However, once those cultivators walked to the city gates, they turned around as they thought of the ongoing Curse Arts outside.
Also, the defensive array of the god city was already activated, so cultivators on the outside could not come in anymore.
An elementary Heavenly God cultivator suddenly blew up not far away from Mo Wuji, and the rotting bloody smell immediately spread out.
