Unlike the previous four-level upgrades, which only took a few minutes, this time the fifth-level upgrade, even if twenty minutes passed, the progress bar was not full.

As for the shelter itself, if levels 1-4 are the real novice stage, humans at this stage are all in the novice village stage.

Then the promotion to level five indicates that the shelter has entered a new level.

From here on, the shelter will enter the advanced stage!

Whether it is the modular drawing materials rewarded by the red envelope in the fifth-level function, or the unlocking of the use rights of many restricted-level design drawings.

As long as it develops for a period of time, even without relying on the system, the underground shelter will completely distance itself from ordinary humans in the wasteland and enter a new era!

[Congratulations to player Sumo, your shelter has been successfully upgraded to level five]

When I heard the familiar prompt sound finally sounded, I didn't rush to preview the conditions of the sixth-level shelter. I lightly dug into the Void Soma, and a design drawing flew out.

Astonishingly, it is a rare-level, small and medium-sized thermal weapon laser manufacturing machine tool design drawing!

This design diagram, which can only be used and learned by spending 500 points after upgrading to the fifth-level shelter, finally revealed its mysterious veil.

But at this moment, Sumo was not in a hurry to learn how to use it. Instead, he followed the passage of the warehouse and returned to the captain's room.

Sitting in front of the table, looking at the rolling waves and occasional tsunami waves outside, as Sumo thought, a notification sounded again.
