On January 1, 2022, doomsday came to the earth, and the whole world would be exterminated.
Jack was accidentally reborn three months ago.
Knowing that the end of the world was coming, he immediately began to build a refuge.
He also activated the Doomsday Survival System, which could help him constantly upgrade his refuge.
The bulky iron door had been upgraded to a titanium alloy fire-resistant insulated door!
The brick concrete walls had been upgraded to special space metal walls!
The power system, pipeline system, material storage system, and active defense system had all been upgraded.
Jack's refuge was as complete and elaborate as a space station!
When the other survivors were still struggling to survive in the ruins of the apocalypse, they suddenly saw a huge refuge.

When Doomsday Comes, I Can Upgrade My Refuge Infinitely

It would take about ten seconds for a metal lift to move up and down once. Transported up to 300 hundred people each time.


It took nearly three minutes for more than 4,000 people to reach the ground.


When the last group of refugees walked out of the lift, Alice finally breathed a sigh of relief.


There was no time to count the number of people, nor did they have any time to group. All refugees chose the route to the tenth underground city in order and began to flee.


They had practiced many times before, so they were not afraid of getting lost or encountering danger.


After all the refugees began to flee in different directions, the survivor team walked behind them to keep the rear safe.


They planned to hold up some mutants from the underground city on the ground.


These mutants became completely furious this time. Unless they were killed by Jack, they would definitely follow these people all the way.
