Dear Father Moran Anderson: Congratulations! Although you never smoked, you have been fortunate enough to be diagnosed with lung cancer at an age when your soul is still fresh. Unfortunately, your business of raising "Children of Hell" is not yet complete, and this Duke has been forced to invoke the "delayed death" clause. After all, these slippery little creatures are far less cuddly than they appear. Please ensure that they are regularly fed with delicious souls, whether human, demonic, or angelic. Don't forget to abide by the "Heaven-Hell Truce" and the "Exorcist Association Management Act." You wouldn't want Michael, Gabriel, and the others to know about our transaction, would you? If you have any further questions, you can consult this Duke directly in Hell. I look forward to the day when I can personally harvest your soul. ———Lucifer, the Arrogant Duke, you are trustworthy...

Ruan Hu became a demon. He turned into a beast on the ridge of the palace, staring at the mortals all day long.

On the first day, he watched the emperor listen to the poem in the imperial garden.

On the second day, he watched the emperor watch the dance and listen to the music in the palace.

The emperor changed beauties one after another, and they had fun every night.

His words could decide life and death, and he could take and give.

On the fourth day, Ruan Hu pushed the emperor into the lake.

He became the emperor.

Under the extreme test of a post-apocalyptic environment, the survival of human civilization and the choices of humanity—when survival instincts collide with moral bottom lines, when individual strength intertwines with collective destiny, is the apocalypse the end of civilization or the beginning of reconstruction? This novel will explore the survival and transformation of civilization in extreme environments through the intertwining of genetic technology, the struggle for survival, and the struggle of humanity.

II. Worldview Setting

2.1 Doomsday Triggers: Triple Screening

Genetic Virus Outbreak: In 2077, a genetically modified virus called "Crimson Dawn" escapes control, capable of rewriting the genes of almost all organisms, causing terrifying mutations in all life forms worldwide. This virus can infect all life on Earth, including humans, becoming the first screening factor in the collapse of civilization.

A red fog descends: After the virus outbreak, a mysterious red fog appeared in the sky. This fog is actually a "gene filter" from an alien civilization, capable of activating hidden potential in biological gene chains and accelerating biological evolution. However, it also leads to instability in biological genes, causing uncontrolled mutations.

Remnants of nuclear winter: In an effort to control the spread of genetic viruses, governments worldwide launched "Project Ice," using biotechnology-based "freezing bombs" to turn low-lying areas of the world into ice ages, triggering a global nuclear winter. Residual radiation caused some areas to become "dead zones," but it also gave rise to the rare resource "radioactive nuclei."
