In 2077, the "Scarlet Virus" swept across the world, turning 90% of humans into bloodthirsty zombies, cities in ruins, and order collapsed. Special Forces soldier Fat Qi, a fierce warrior whose name seriously does not match his body shape - he obviously has a well-proportioned and standard fighting figure, but he was named "Fat Qi" because of an omission when he joined the army. When the apocalypse broke out, he was performing a secret mission. After surviving by chance, he ran rampant in the ruins with a "shut-up rule": anyone who disobeyed instructions, regardless of whether he was male or female, old or young, close or not, would be thrown directly to the zombies or killed on the spot, without saying a word. Only an absolutely beautiful woman can break his iron rule and grant him special protection. This ultimate double standard has become the strangest survival signal in the apocalypse where zombies surround him. When the decisive and ruthless Fei Qi walks through the tide of zombies with his "Double Standard Rule", horrifying mutated zombies, treacherous survivors, and safe zones with hidden conspiracies follow one after another. Every breakout is accompanied by blood and reversal, and his "Shut Up Rule" and double standard bottom line are constantly being challenged on the verge of life and death.
