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

After much deliberation, Jera still hadn't come to an accurate conclusion.


When she was about to give up, the male assistant beside her connected the direction of the two giant beasts for some unknown reason.


The result was a diagonally straight line.


"Stop! Don't move!" When she saw this straight line, she suddenly became very excited!


Because on this straight line, there happened to be the central city No. 4, the central city No. 2, and the central city No. 1!


These two damn beasts seemed to want to converge!


They were moving slowly towards each other at a very fast speed.


In this case, the Arctic radiation giant bear would arrive in New York in less than three days!


"Contact the military as soon as possible and tell them the discovery I've got. The Arctic radiation giant bears will attack New York in two to three days!"


Jera quickly told her conclusion to her assistant.
