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 thick ice began to melt slowly, and a large number of victims' bodies under the ice appeared.


The mutants underground didn't act. The terrible glacier era had a great impact on their survival.


Maintainer I and Creator I had repaired all the damage caused by the army to the refuge not long ago, and they had also strengthened the self-recovery function of the refuge.


Now the attacking and defending ability of the refuge had more than doubled.


Jack used 1,000 survival points to let the guards have the flying ability. Because they were made of special metal and were not afraid of cold. They could fight in the crater cave every day.


The temperature that had just risen for a few days suddenly dropped in the evening, and the water on the ground slowly turned into ice.


The temperature went back to 0, but it was not as serious as before.
