In the ordinary daily life of the prosperous city, Ah Pang, a slightly fat young man who is obsessed with doomsday science fiction, shuttles through the hustle and bustle every day, but he has a vague premonition of crisis in his heart. When the apocalypse came without warning, the city instantly fell into ruins, and human beings disappeared like dust. With years of obsession and preparation as a doomsday fan, Fatty hid in an underground safe house built by himself, and luckily became the "last man" on earth.
In the beginning, fear and loneliness went hand in hand. Fatty struggled to survive by hoarding supplies in the safe house, fighting his inner demons in despair. But as time goes by, his desire for his own kind drives him out of the safe house and into the dangerous wasteland. Along the way, he encountered ferocious attacks from mutated giant beasts, struggled to survive in strange energy storms, and fell into the trap of a mysterious organization, narrowly escaping death.
However, Fatty never gave up. He explored the ruins of the wilderness for clues to ancient civilizations and discovered that the end of the world was closely connected with out-of-control experiments; he met the resolute Ellie in a ruined town, and the two worked hand in hand to solve numerous mysteries and move toward the light of hope that would revive the world. From an ordinary person struggling for survival to a lone hero shouldering the destiny of mankind, Ah Fat forged ahead in the blood and fire of the apocalypse, writing legends with courage, wisdom and hope, just to find the dawn of human rebirth in a desperate situation.
