Currently, Lucas had quite a few things at his disposal.
He had a heavy knife, a sniper rifle, a crossbow, a metal shield, a handgun, and a combat suit.
There was a scouting drone, a suicide drone (usable with the combat drone control station), a robot (the mute girl), a pair of dual blades for the mute girl, as well as a bus, a motorcycle, and two Level 1 nutrient-rich soils.
Calculating the approximate half-month since the apocalypse began, Lucas had acquired quite a lot of good things from the system.
After consuming the red capsule, Lucas began to modify the bus.
This time, Lucas had no idea what he could modify or upgrade on the bus.
The system never provided specific numerical values for bus modifications; it felt like it was relying on luck.
A panel popped up, displaying a three-dimensional blueprint of the bus.
Sure enough, there were many green "+" signs on it.
Upon closer inspection, the options were similar to when the bus was upgraded to Level 2 last time. Lucas's gaze stopped on the options involving spatial technology.
"+" sign [Kitchen Space *]
"+" sign [Bedroom Space *]
"+" sign [Healing Chamber *]
On the diagram, there were three items with an asterisk "*", which made them appear more special.
Last time, Lucas believed that if he chose one of these three options, all the numerical values would be reset.
This time, because he wasn't alone anymore, Lucas decided to upgrade something practical.
But there was more than one option for practical upgrades. Lucas looked at another batch of "+" signs.
"+" sign [Storage Room Partition]
"+" sign [Bedroom Partition]
"+" sign [Bathroom Partition]
"+" sign [Increase Vehicle Length by 1m]
"+" sign [Increase Vehicle Height by 10cm]

"+" sign [Increase Vehicle Width by 10cm]
Increasing the vehicle length by 1 meter and the healing chamber were both desirable for Lucas.
In the end, Lucas felt that the healing chamber seemed more important for a team.
Increasing the vehicle length by 1 meter wouldn't actually allow for much extra storage, while the healing chamber could be a lifesaver.
Lucas clicked on the "+" sign for the healing chamber.
The blueprint of the bus began to refresh, and when the refresh stopped, one of the windows near the bus door disappeared, replaced by a door that matched the color of the interior.
If one didn't look closely, they wouldn't even realize it was a door.
In the middle of the door was a red cross symbol.
"So, this is spatial technology?"
Lucas looked at the place where the window used to be, now transformed into a door.
Who could have imagined that behind this door was an extra space!
At least Lucas had never seen anything related to spatial technology in his past life.
Is spatial technology science or theology after all?
With this unanswered question, Lucas pressed on the red cross on the door.
Snap—
The door made a slight crisp sound and slid to the side.
Lucas grew more and more excited. This feeling was like exploring a game, filled with mystery.
As expected, after the door slid open, he saw what looked like a starry sky inside.
The brightness of the starry sky wasn't high, and there was a vortex in the middle that kept rotating.
Lucas felt that this was probably what a portal looked like in the comics he had read.
Without hesitation, Lucas took a step inside.
In an instant, his surroundings flashed, and Lucas found himself in what seemed like a makeshift operating room in a hospital.
However, this operating room was somewhat crude, and it was quite different from what Lucas had imagined before entering.
At this moment, the system panel suddenly appeared in front of Lucas, displaying a three-dimensional blueprint of a healing chamber.
Above the blueprint were the words [Level 1 Spatial Healing Chamber].
Similar to the bus blueprint, it also had many gray "+" signs. Lucas carefully examined it and had a general idea.
Currently, the healing chamber could only be considered a normal treatment room. Inside, there seemed to be various medical equipment and a cabinet for storing medicines, but it could only treat normal illnesses and injuries.
Lucas could clearly see that the "+" signs on the healing chamber blueprint didn't represent additional equipment or medicines, but rather an enhancement of the treatment effect.
The items inside were also categorized by levels. Only at Level 2 and above could the healing chamber treat injuries caused by red-level creatures and infections. In other words, a Level 2 healing chamber had a certain chance of preventing infections.
Its current effect was not significant!
After reaching a conclusion about the healing chamber, Lucas immediately thought of using it as a warehouse for now. After all, the space here was quite large and could hold a lot of things.
Without hesitation, Lucas quickly filled the healing chamber with food, water, and gasoline.
Before coming to this upscale residential area, Lucas had never imagined that there would be a small gas station specifically serving these dozen or so families.
This kind of service was indeed great.
Now, Lucas had more gasoline inventory than when he had left it in the underground warehouse.
Using up all the upgrade values for the bus on a Level 1 healing chamber seemed worthwhile to Lucas. It could both treat injuries and serve as a warehouse.
Lucas decided that for future upgrades of the bus, he would first add the spatial technology options before considering other upgrades.
After adding the healing chamber, the upgrade values for this round of bus modifications were completely used up as expected.
Then, Lucas's attention shifted to the body modification fluid.
[Body Modification Fluid]
1.Increase a specific physical attribute by 100 points.
2.Alternatively, choose to increase three physical attributes by 35 points each.
Looking at the description of the body modification fluid, Lucas opened his own physical attribute values.
His strength and stamina were already over 100 points, and even his skin hardness, although not exceeding 100 points, was in the inhuman range.
There were many attributes to choose from with these 100 points, such as vision and hearing.
After some thought, Lucas selected vision, hearing, and skin hardness, each increased by 35 points.
Swallowing the transparent liquid provided by the system, Lucas didn't feel anything particularly special.
He checked his physical attribute values.
Skin Hardness: 78 (Inhuman, 50% chance of immunity to infections from red-level creatures and parasites.)
Vision: 84 (Excellent vision for a normal person)
Hearing: 81 (Excellent hearing for a normal person)
"It seems that except for skin hardness, the other physical attributes at 100 points are the dividing line between inhuman and normal people."
Lucas murmured to himself, then looked at the final reward, three red blank blueprints.
Strictly speaking, apart from the bus upgrade, the thing Lucas valued the most was the blank blueprints.
As long as he could draw on them, the blank blueprints could manifest into reality.
Lucas approached the use of these three red blank blueprints with caution.
Should he create weapons, or some auxiliary or lifestyle items? Lucas had too many thoughts and couldn't make a decision at the moment.
After all, there were many real-life problems that needed to be faced now.
