Ninety days countdown to the solar flare, the global will welcome a long polar night of minus eighty degrees. Ou Runji, the cold-chain warehouse manager who froze to death in a bridge cave in his previous life, was reborn back to March before the freezing descended and also bound with the "Doomsday Warehouse System". In this life, he no longer endures. Zhou Jinbiao's smuggling ledger, he handed it to the inspection desk that very night; Luoye's threat, he rebutted right in front of all the guests with a sentence "Get out of Yunshan within three days". Co-opting the gang leader of Trump Tang Yaomei, rescuing the Taiwanese-accented accountant Lin Yuqing, taking in the retired military doctor Shen Bing, he hoarded the abandoned combat readiness warehouse on the top of Yunshan Mountain into a fortress sufficient to resist the entire cold winter.
