Resurrection Crystal inside.
Most resurrection-type facilities essentially temporarily store souls in a special space that doesn't interact much with the real world, with the sole link being the resurrection facility itself.
This also means that once there is a problem with the resurrection facility, that space becomes detached from the real universe, becoming a completely independent small world, and this situation is what the Gods call—a broken device.
Now, there were already long queues forming in this space, and more people were continuously coming in from the external space—although the facility was clearly broken, it wasn't completely out, and the original "absorb-resurrect" bidirectional channel had turned into a one-way street.
The juniors who were subsequently brought in also began to point fingers at their utterly unhelpful seniors, especially senior Ceylon, blaming him for initiating the "Era of Mass Death!"
