Rebirth at the End of the World: I Have a Shelter System

Reborn before the apocalypse, ordinary salaried men who were heavily in debt did not choose to save the world. He just wants to live. Extreme cold, power outages, heavy rains, mutated creatures, and the subsequent collapse of order will all come one after another in the future. With an incomplete rebirth memory, he must raise money, stock up on goods, buy a remote underground industrial facility while everyone is still immersed in normal life, and transform it into a private fortress that can withstand disasters and people's hearts. Food, drinking water, medicine, fuel, equipment and weapons, every expenditure must be accurately accounted for; relatives and friends, debts, real-name transactions and logistics traces, every check may expose his secrets. But when the disaster really materialized, material prices went out of control, and survivor organizations, looters, and the remnants of the official forces came one after another, he discovered that the most difficult thing to prevent was never cold waves and floods, but the people who knew there was something in the fortress. In this life, he doesn't owe anyone. He has only one goal: to protect his own life, his own fortress, and his right to refuse to have his life and death decided by others in the apocalypse.
