Another ten years have passed.
The amount of Demonic Qi in the Demon Realm has approached zero.
This essentially means that this world has taken off its last suit of armor, and if one wishes, could readily devour it, plunging it into a state of disarray governed by chaotic rules.
But no one did so.
Because doing so would mean that the Heavenly Gate no longer exists, and no one would be able to withstand the wrath of the thirteen Demon Emperors outside.
Until now, even Wei Cheng hasn't been able to affirm whether those thirteen Demon Emperors are aware of the situation in the Lower Realm.
Therefore, as expected, after ten years of struggle, the five quasi-Demon Emperors finally reached an agreement with the leader and the second and third-ranked members of the Heavenly Demons.
With this agreement in hand, they came directly to the Human race's Mountain Sea Legion, summoned Cheng Zhihuai, and issued an ultimatum.
