This story begins in 2013. Mobile internet was booming, and everything familiar was undergoing rapid change. New trends emerged, challenging the traditional values of an ancient nation. It was a year of turmoil and prosperity. Some said it was a time of declining moral principles and a decline in moral values, perhaps the worst of times. Others said it was a year of vibrant energy, simplified government, and clean laws, perhaps the best of times...

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."

Black Cat Katie: Am I unlucky? But why is my owner petting and hugging me?

White Tiger Ruixue: I am a tiger, not a cat. Master, stop petting me, or I'll start shedding.

Snow Leopard Annie: I told you, touch them but don't touch me! Okay, okay, just once, just once.

Team cards: sealing large numbers of creatures for combat, acting as summoners. Legion cards: one person forming an army, sweeping across the battlefield, invincible. Nest cards: self-producing and self-consuming, endlessly swarming troops, conquering everything. Environment cards: changing the environment, seizing all advantages. Realm cards: carrying a world with you. …《The Third Evolution of the Heavens》 Billions of years ago, cells appeared on Earth. Active cells began to evolve to adapt to the environment, and were…

(PS: Not invincible, card-based, stitched together, resurrected, reborn, pioneering, or exploring. The protagonist needs to grow and change; failure and setbacks are also part of life, and the character is multifaceted.)
