The Dragon Emperor's Purgatory was actually a prison. 

It was used to incarcerate the criminals of the mystical dragon tribe. 

Moreover, they were basically all offenders that had been sentenced to death. 

Some of them were immortals or ghostly immortals. 

However, the majority of them were mystical dragons. They had committed heinous crimes, brought harm to their own kind, or betrayed their comrades.

The mystical dragon tribe had a long history. There were lots of immortals that had harmed mystical dragons.

In fact, the number of people in it was still increasing. 

The Dragon Emperor's Purgatory would be opened once every thousand years for the younger generation of mystical dragons as a trial. 

The nine major tribes would take turns to open it. 

It had been 9,000 years since the Sky Heart tribe opened their Dragon Emperor's Purgatory.

This time, it would open in seven years.

The Primordial Immortal Empire had three slots. 

The assessment today was to determine who would receive the rights for the three slots. 

All three of them were fresh and had not participated 9,000 years ago. Moreover, they were all sons of dragon kings and below 20,000 years old.

The truth was that anyone below one yuan of age would fulfill the requirements.
