'Something is wrong,' thought Wang Wei. The Clean up is a generational event where cultivators of the Myriad Emperor World essentially go on a slaughter spree in the Nine Devil God World, culling the strength of the devil race. The purpose is to prevent any possibility of rising.
Although it was a generational event, not everyone participated. And sometimes, only a few people do so–mainly Loose Cultivators since it is an excellent opportunity to gather resources in another world.
This event had the most significant after the Devil Era. Back then, cultivators were full of hatred and animosity and took it out on the surviving race. In the next few generations after the end of the era, the devil race was almost extinct because of how much people hunted them down.
Typically, the Clean Up should not be important in this generation, nor did it warrant an announcement from Heavenly Dao. But this has changed today because the cleanup involved the Heaven Will Battle.
