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

In the face of the rapid and fierce attack of super bodies, the super mechanical soldiers instantly activated the upgraded polymeric handgun with the function of particle decomposition in their hands.


An extremely terrifying beam of energy was shot out at a high speed. It was unknown how many times stronger their energy was than Union's.


In just a round of ordinary shooting, the Scientific Research Institute's scientists found that those super bodies that could not have been damaged suddenly evaporated.


After emitting white steam, their bodies disappeared with it.


After the first round of shooting, more than one thousand super bodies turned into air.


But it wasn't all the army Jack had sent.


Behind super mechanical soldiers, more than a dozen Divine Bird fighters came over from the void and avoided the Union soldiers. They accurately dropped a few powerful energy missiles.
