The Seven Killings Secret Realm is the secret realm used by the Seven Kills True Monarch to select disciples for inheritance.
It is said to be created using a fragment from the Middle World, hence there are no taboos.
Theoretically, experts of the Eighth Tier can also enter.
However, because it is used by the Seven Kills True Monarch to select disciples for inheritance, there are still restrictions on entry.
One of the biggest restrictions on entry is age!
Under twenty years old, as long as the cultivation level reaches the Third Tier, one can enter.
Under twenty-five years old, the cultivation level needs to reach the Fourth Tier.
Under thirty years old, not only does the cultivation level need to reach the Fifth Tier, but entry is allowed.
Under thirty-five years old, the Sixth Tier can enter, a cultivation level reaching the Seventh Tier, under forty years old, can enter.
The Eighth Tier can also enter, but the age requirement is under forty-five years old.
