"Why should we be anxious? We don't have the strength to resist anyway. The ones who should be anxious should be the Emperor Clan!"
An Immortal King revealed the truth.
Indeed, compared to Immortal Kings like them, the ones who should be anxious should be the Emperor Clans.
Basically, this was because Immortal Kings were unable to resist the Heavenly Court. The Heavenly Court controlled more than 50% of the Heaven Realm's strength. Even if these Immortal Kings joined forces to oppose, they wouldn't defeat the Heavenly Court.
Some Immortal Kings were roaming outside the Heavenly Court and weren't under their control. The underlying reason was that they belonged to Emperor Clans.
These independent Emperor Clans were the reason why the Heavenly Court's strength was scattered.
