Two months later, Huang Yu finally returned from the Abyss.
During those two months, Huang Yu had collected information on the plane worlds reached by the existing Abyssal passages in the Flowing Pulp Plateau.
The Abyssal passage located in the Magma Sea led to the Crimson Purple Demonic Domain on Abyss Layer 68, the ancestral homeland of the intermediate demon races known as red demons and purple demons.
As remarkably intelligent demon races, the red demons and purple demons of the Crimson Purple Demonic Domain had already established several factions and a sound social system.
Several Demon Lords existed in the plane, but there had never been any word of an Immortal Demon King residing there.
When Huang Yu sent people to investigate the Crimson Purple Demonic Domain, demons from the Crimson Purple Demonic Domain also passed through the Abyssal passage and arrived at the Flowing Pulp Plateau.

They died without leaving so much as a corpse almost the moment they arrived.
In the end, only one Extraordinary Great Demon had barely survived and escaped back to the Crimson Purple Demonic Domain.
After that, the demons of the Crimson Purple Demonic Domain never sent anyone to investigate the Flowing Pulp Plateau again.

That was because its ecology was relatively suitable for permanent human settlement, and its resources were abundant.
Most importantly, no Demon Prince had yet been born in the Crimson Purple
