After Chen Mo broke his cervical spine in the water prison of the Donghai Chamber of Commerce, he was reborn on August 18, 2028 - 30 days before the outbreak of global rules. In his previous life, he died from a game of rules, and his sister died tragically from the evil of human nature. In this life, he carries his memories of the doomsday to prepare: using Bitcoin to forge his identity, laying lead sheets in air-raid shelters, avoiding dangerous cans, and rescuing his sister Lin Wan from his aunt.
Rules are coming like a plague: "Revelation" written in blood on the Lujiazui curtain wall causes the brains of those who look directly to melt. The handrails in subway stations now read "If you hold them for more than 10 seconds, they belong to the 'iron'" causing a stampede. The temperature of 25 degrees Celsius has become a life-and-death line that isolates monsters. Chen Mo formed an alliance with his sister and veteran Chu Hang, who had awakened the power of predicting rules. As a "rules auditor", he cracked the "even-numbered layers of forbidden words" and other treacherous rules, and fought against the pursuit of Su Linyuan, the young master of the East China Sea Chamber of Commerce. When Lin Wan's sketch predicted that the air-raid shelter would be swallowed up by bloodshot threads and the whole city would fall into the final rule of "60 seconds of darkness owned by the 'Shadow'", Chen Mo injected three times the stabilizer and set up a counterattack in silence at the risk of smiling facial paralysis. The truth of the rules is related to the barrier pierced by the sister's hairpin and the 532THz frequency of Su Linyuan's collar needle. This is an apocalyptic bloody game with temperature as the shield and rules as the blade.
