Living on an island controlled by demon cultivators, mortals are nothing but ants in their eyes, an endless supply of tools.
The mortals on the island take care of the Fallen Heaven Silkworms and weave them into Thousand Souls Silk, working hard just to barely survive, while the demon cultivators periodically extract their essence blood.
For cultivators, essence blood can slowly recover, but mortals cannot, so after just a few extractions, mortals die from being drained of their essence blood.
This leads to the average age of mortals on the island being only forty or fifty before they die from a lack of essence blood.
Chen Nan stood on the island, feeling that this island was like a huge cage, binding these mortals here, forever unable to transcend.
His heart felt a bit desolate, but he was powerless to change such things.
