Zhang Yang was an orphan, his parents top biologists who died in a lab accident when he was young. He was adopted by a wealthy elderly man who later died of cancer, leaving him tens of millions in cash and shares worth hundreds of millions. Seven days before the apocalypse, a translucent panel appeared in Zhang Yang's vision: a countdown to the end, a 100% mutation probability, and a message that he would become a zombie retaining his mind—flesh and blood would fuel his evolution to become the Zombie King. Believing the panel, Zhang Yang decided to exchange all his assets for flesh and blood. He withdrew all cash, borrowed from banks and loan sharks, and purchased tens of thousands of tons of pork, beef, mutton, chicken, and fresh blood, using installment payments to maximize quantity. He stored the meat in a cold warehouse before secretly transferring it into the panel's time-stilled storage space of one billion cubic meters.His third uncle Wang Dali, who coveted Zhang Yang's inheritance and managed the group, came to scold him for wasting money. Pretending remorse, Zhang Yang offered to sell his 37% shares to Wang Dali for a lump sum of 200 million yuan, well below market value. Wang Dali eagerly accepted, giving Zhang Yang fresh cash for more meat. Zhang Yang also fortified his villa with steel guardrails, high-voltage fences, diesel generators, water purifiers, gaming systems, and cold weapons to prepare for his life as a rational zombie.On the seventh night, a blood moon appeared and an energy tidal wave swept the world, turning 70% of humans into zombies. Zhang Yang fainted and awoke as a zombie, still fully conscious. His panel updated: race zombie, potential King Level (ranking from Common to Catastrophe), stage Zero Stage (0/100), talent Devour (energy from flesh), King's Potential (command lower zombies), superpower Psychic Power, and storage space. He could not eat human food—tasting an orange was bitter—but when he devoured raw meat, it was delicious and gave him energy. Every 10 kilograms of flesh provided 1 energy point; advancing from Zero to First Stage required 100 points, or one ton of meat. He spent the first night consuming meat nonstop, accumulating 100 points and advancing to First Stage. His body control improved, movements became less stiff, and his psychic power strengthened. The 50,000 tons of meat in his storage represented over 500,000 energy points, enough to reach high ranks without external hunting.Through television, he learned that human shelters and evolvers with superpowers were organizing, while mutant creatures were classified by threat levels. Zhang Yang realized his King potential, his retained intellect, and his massive flesh stockpile gave him an enormous advantage. He vaguely recalled his parents injecting him with a green serum as a child, calling it their last gift, likely the reason for his sanity and high potential. Now, he continued to devour meat, aiming to soon reach Second Stage and beyond, determined to become the absolute Zombie King commanding countless mutants in the apocalypse.
