The Immortal Herbs Secret Realm is a training ground for Saints below the Fifth Heavenly Layer.
Powerful beings above the Fifth Heavenly Layer find it difficult to enter.
In fact, across the vast Red Ming Domain, there are other secret realms of higher levels that have been opening up recently.
But Qin Chuan chose the Immortal Herbs Secret Realm.
Mainly because...
It's a matter of cultivation!
Qin Zi's cultivation is currently only at the Third Heavenly Layer Saint level, and he might have recently broken through to the Fourth Heavenly Layer. If he were to cause trouble in a secret realm of the Seventh or Eighth Heavenly Layer, or even an emperor-level secret realm, his cultivation wouldn't match up at all.
By then.
Qin Zi arrives at the Red Ming Domain, and if he's only at the Fifth or Sixth Heavenly Layer in cultivation, others might see and question, "Huh? How has your cultivation decreased so much, you scoundrel?" He'd be busted immediately!
