Countdown to Cataclysm: a Well Was Dug at the Beginning

"Su Yan, do you still want to pay the rent?" On September 14, 2016, Su Yan opened her eyes in the rental house. The landlord on the phone was urging me to rent, and the card contained 820 yuan. No one knew that ninety days later, extreme cold would hit overnight - the power grid collapsed, the temperature dropped to minus 60 degrees, and the entire Cangjiang City froze into a shell of ice. In his last life, he failed to take his mother back, failed to keep the rental house, and finally died in a flood ten years later. In this life, he came back with a complete disaster script. The time, form, and fatal details of each wave of disaster; every safe zone, every batch of key supplies, and every person who can survive. Ninety days, eight hundred and twenty yuan. The first thing he did was to go to the abandoned factory building that no one wanted in the west of the city and dig the deep well. The only thing he didn't know was that he was not the only one who remembered this script.
