Nether Purple Mountain pressed down on over a dozen Celestial corpses. If not for that, people would have noticed over these 30,000 years.
The reason why they were noticed now was because Nether Purple Mountain wasn't as strong as before.
At the moment, it was extremely sick and would occasionally be unable to control itself.
The last time it lost control was seven days ago which revealed the tombs. The treasure energy surged into the sky and it lit up half the sky.
Even after a Celestial died, their thick aura would spread about. It was really scary and just one look and a person would be able to notice it.
As a result, the factions and aristocratic families nearby all gathered in Eighteen Mile Region to start to search for the tombs.
Nether Purple Mountain didn't have the strength to bother about outside matters, so it allowed them to search. As long as it didn't lose control again, these people wouldn't be able to find it.
