Heavenly Tribulation

Heavenly Tribulation
When something is going to defy the natural order and isn’t accept by the heavens, at that point of time, the Heavenly Tribulation will appear as punishment and destroy that thing. Anything that has strength greater than the realm can contain will be considered something that defies the natural order, and it will not be accepted by this realm. Therefore, a Heavenly Tribulation will appear to eliminate them. If the one that goes through the Heavenly Tribulation survives it will be accepted, but if it can not survive it it will turn in to ashes and die on the spot.
