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

The actions of the world mercenary regiment soon attracted the attention of the other mercenary regiments. Except for the world mercenary regiment, three mercenary regiments were now carrying out the population transfer.


The whole black blood mercenary regiment moved to a plateau area about 300 meters higher than the plain area, which was a little far from Los Angeles.


They were busy settling down in their base and home.


There were not so many people in the ark mercenary regiment, so they directly evacuated all people to a low mountain with open space.


They had set up many tents on the hill and taken measures to protect themselves from lightning and rain.


The twilight mercenary regiment directly built a high-rise building in their base, so they simply didn't want to move.


Obviously, they just wanted to avoid the flood disaster temporarily and did not intend to carry out a long-term migration.
