Cladema, the God of Underground Caves and Relics, was the only victim of the 'Yin Chen' incident.
Even the adventurers in the amusement park of Dragons and Dungeons weren't killed or injured, except Cladema.
This was certainly due to the admirable emergency measures the amusement park had taken, and the tourists who had been in Dragons and Dungeons had each carried a special magic tool. If they were seriously injured or felt extremely hungry and tired or met with danger, they would automatically be transported outside of the adventure park, rather than returning to the city or to the exit. In fact, they were transported directly to the clinic.
The clinic was the strongest and safest building in the whole adventure park. Even if it collapsed, people in the clinic wouldn't see any danger, not to mention that the clinic wouldn't collapse.
