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

"Creator I, what's wrong with you? Are Creator II and Creator III surpassed you now?"


Jack was curious when he saw Creator I was depressed.


"Oh, of course not. I just found that some of the metal on the superheroes' bodies was dissolved by the venom. My work is not perfect anymore."


Creator I slapped his thigh, looking very irritable.


"It doesn't matter. You have done a good job."


"Now that you have doubts about your ability, I will find a way to make you stronger."


Jack touched Creator's head and woke up the refuge system.


"System, I want to pay 2,000 survival points to upgrade Creator I by 20 levels!"


Jack now had endless points. He would reward the best labor model.


"Wow, I know how to improve the metal on the superheroes!"


Creator I immediately solved all the doubts in his mind by the time he was upgraded.


He ignored Jack and devoted himself to his work.
