The extraterrestrial space pollution invasion triggered by the Blood Sun Seal was terminated within 12 hours.
However, the turmoil and aftermath caused by this event lasted for several days.
As Noland Lee predicted, the Fissure Corridor experienced severe collapse. From the 30th underground layer to the layer where the Black City was located, all showed signs of broken wall bricks and collapsing corridors.
Fortunately, when the Alchemy Cathedral built the Fissure Corridor, they took into account this extreme situation. They used hard alchemy rock layers to separate the Lower Town's foundation from the Fissure Corridor.
The entire foundation of the Lower Town was built on this alchemy rock layer, without directly connecting to the Fissure Corridor.
Because of this, the buildings in the Lower Town were spared from disaster.
