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 didn't wake up until the second day. When he got up, Jack instantly received a message from the system.


"Dear master, the fifth round of doomsday disaster is coming. Please make adequate preparations."


"The theme of this doomsday disaster: The flood eruption!"


"In order to resist the life risk caused by the fifth doomsday disaster, the system has specially sent a special gift."


"Congratulations, you've obtained a rebirth card!"


"What? Is there such an item?" Jack opened his eyes, surprised and pleased.


"System, I want to check the specific effect of the rebirth card. I hope you can help me." Jack said in a low voice.


"Effect: before master's life is completely destroyed, the rebirth card will help you instantly open the time-space passage, letting master instantly go to another space through the time-space passage, and get a 100% rebirth effect!"
