2 Chapter 2 Upgrade the Refuge
To determine whether the system could upgrade his refuge.
After hesitation, Jack decided to spend 300 survival points to upgrade the iron door to a titanium fire-resistant insulated door and add a lifting system.
Jack reached over and clicked the upgrade options on the panel in front of him.
"Titanium alloy fire-resistant insulation door plus lifting system had been upgraded successfully!"
"Survival point cost: 300."
When the message flashed on the panel, the iron door suddenly began to twist the next second, and a white light instantly covered it.
Less than a minute later.
The heavy iron door directly turned into a very exquisite and highly scientific and technological titanium alloy fire-resistant insulation door.
The titanium door can not only open and close automatically, but also had a lifting system under it.
So that Jack didn't need the staircase and could dismantle it to save more space.
After confirming that the system worked, Jack was pleasantly surprised.
He moved on and upgraded the rest of the refuge.
The first step is to expand the refuge. Otherwise, upgrading some individual facilities would have overwhelmed the refuge.
"The space of the refuge."
"Upgradeable direction:"
"1. Expand the area, every one m, cost three survival points."
"2. Raise the height of the floor, every ten cm, cost ten survival points."
Jack looked around the refuge again and decided to expand the area by 100 square meters and raise the height of the floor by one meter.
Because of the larger space, not only can it accommodate more shelter facilities but also store more survival supplies.
Jack would be more comfortable living in.
"Refuge area and storey height have been expanded successfully!"
"Survival point cost: 400."
When the panel flashed a message, the refuge suddenly changed dramatically.
After expanding the area to 100 square meters and one-meter height.
The refuge suddenly looked more spacious and brighter, and without the previous feeling of oppression caused by the narrow and low space.
With a bigger space in the refuge, Jack could move on to upgrading other facilities.
To resist all kinds of disasters after the apocalypse.
The first step was to ensure the refuge's external firmness, corrosion resistance, fire resistance, heat insulation, frost resistance, insulation, and other properties.
Therefore, the upgrade of the exterior wall was particularly crucial.
Jack rushed back to the ground through the lift system and then looked up the outer wall of the refuge.
These walls were made of ordinary bricks. Although they were very thick, they might not be able to hold on for too long under the destructive force of the apocalypse.
"Ordinary brick wall."
"Upgradeable direction:"
"1. Sturdy metal wall, anti-impact, waterproof, thermal insulation, thermal insulation and other properties in general, consumption of 1000 survival points."
"2. Special space metal walls, excellent anti-impact, waterproof, thermal insulation, thermal insulation, consumption of 2000 survival points."
The wall had two upgrade directions, and the second one was better.
Of course, more survival points were consumed, and now there were only 9300 survival points left.
"The exterior wall must be upgraded to the best!"
Without hesitation, Jack gritted his teeth and chose to upgrade the wall with a second special space metal.
"Special space metal walls had been upgraded successfully!"
"Survival point cost: 2000."
Soon, the outside was covered with some dirt, and the walls made of bricks and concrete turned directly into walls of a special metal material.
And because of its increased thickness, the bunker's outer walls simply burst through the ground, protruding at least 30 centimeters.
But Jack didn't care about that.
With this powerful Doomsday Survival System, his refuge would be completely out of the ground and a larger refuge would be established!
After the critical wall upgrade, Jack didn't immediately return to the refuge.
Instead, he was curious to see whether the special space metal walls could continue to be upgraded.
"Special space metal walls"
"Upgradeable direction:"
"1. Increase the automatic repair function of the wall, consuming 2000 survival points."
"2. Strengthen the comprehensive defense performance of the wall, consuming 1000 survival points."
Sure enough, although the space metal wall was powerful enough, it could continue to upgrade.
But Jack didn't continue to upgrade, because they consumed too many survival points.
He didn't think it was necessary right now.
Then Jack returned to the refuge.
Start upgrading other facilities in the bunker, such as power systems, plumbing systems, and material storage systems.
Half an hour later.
Jack's refuge not only has all the necessary facilities, but it was also very exquisite, completely like a space station with high technology.
Now in the refuge, Jack didn't have to worry about the power failure and the pipe congestion.
There was even an automatic temperature and humidity control system in the refuge, so there was no need to worry about extreme weather outside during the doomsday.
However, after upgrading these, Jack only had 1000 survival points left.
Although Jack found that the survival points could exchange for various living resources such as food for him, he didn't want to continue to consume them.
After all, he didn't know how many survival points would be obtained later.
To prevent other unexpected factors after the apocalypse, he had to keep some survival points.
"I still have some time. I'd better replenish some supplies by myself."
Then Jack left the refuge, returned to the ground, and drove towards the downtown.
Jack planned to exchange all his savings for supplies, including food and water.
Even weapons.
In Jack's memory, after the doomsday came, humans would not only face the disaster of nature, but also the test of humanity.
Jack had to prepare in advance and store some weapons in the refuge.
Driving on the quiet road, Jack couldn't help but take a few more glances at the scenery around.
He knew that before long, the world in front of him would become a purgatory.
But only he knew that.
At this time in the city, people are still immersed in the enjoyment.
Although signs of the apocalypse had appeared, they were all very confident that there would be no doomsday in this world.
"Alas!"
Jack sighed helplessly.
Recall the scene after the apocalypse, the outbreak of solar flares, earthquakes, tsunamis, hurricanes, and other disasters.
Even all kinds of creatures have mutated.
Thinking of this, Jack couldn't help but show a terrified look in his eyes.
