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

Jack knew what Jera was going to say even if she didn't open her mouth. After hearing her request to leave, Jack didn't say anything for a long time.


Jack put his right hand on the p95 pistol in his right pocket.


He was hesitating whether he should kill her or spend more time persuading her to stay.


For a long time when Jack was busy building the refuge, Jera wandered around the refuge every day. She secretly studied the structure and system of the refuge, and now she has made a very systematic theory.


She had to bring this theory back to the organization so that humans could build more refuges like this in the future to deal with the doomsday disaster.


Besides, she had her father, mother, brother, and sister. Since the doomsday had begun, she had completely lost contact with her family.


Only when she returned to the ground could she have the chance to reunite with her family.
