My Post-Apocalyptic Shelter Levels Up Infinitely!

Under the golden sunlight, Earth Tiger slowly drove along and into the plains…

Looking at the Deep-sea Shelter buried in the dirt outside the car window, Su Mo shook his head regretfully and continued to drive forward.

After last night’s light snow and the large drop in temperature, judging from the morning sun, today was another day full of “hope”.

Although it was around seven o’clock in the morning, the temperature was rapidly picking up at an unusual rate.

At night, it was still ten degrees below zero. At six o’clock in the morning, the temperature reached ten degrees above zero again, and it was still increasing to fifteen or sixteen degrees at this moment.

In this kind of weather, the ice that did not freeze over yesterday would continue to melt together with the snow below.

The consequences of such frequent fluctuations were not clear to Su Mo, but he could hazard a guess.

“All shelters are currently working hard for the three-day supplies for this disaster, but in this situation…”

“I am afraid that even after a week post-disaster, it would not be easy for humans to go outdoors!”

As far as the naked eye could see, there were large swathes of icicles. In this kind of weather, not many could survive in the wasteland.

If human beings wanted to get supplies, they would be forced to find and fight the alien races in order to secure hope from the battle between races.

“The so-called survival game is to kill all competitors and survive to the end?”

While he could not really figure out the deep meaning behind the game, looking at the Underground Shelter’s hill that appeared in the distance, Su Mo felt happy.

Every time he went out, there were gains, which is undoubtedly the best consolation for having taken that “risk”.

Although it was as Oreo predicted, there were injuries all over his body, but compared to the development and upgrade of the shelter, this was nothing!

“One day, I will make the surrounding basin rich and make this a treasured land that all humans dream of!”

Looking at the barrenness of the basin and thinking about the fertile lands of the shelter in the west, Su Mo did not lose heart, but was full of energy.

Entering the password and pulling on the winch, Su Mo opened the garage gate of the Underground Shelter and parked Earth Tiger safely inside.

Glancing at the rising sun, Su Mo slowly wound down the winch and closed the gate, completely shutting out the light!

Rushing into the kobolds’ castle In the middle of the night; how many survival points could be gained from that, Su Mo did not know. What he did know was that this core alone was worth it and would make him a lot of money!

Taking off his outer armor and combat uniform, Su Mo grinned and slowly took off his sweater, revealing the muscular body underneath.

From the neck down to the calf, there were big bruises every few centimeters, accompanied by a large number of smaller wounds that had stopped bleeding.

Looking down at his inner thighs, it had turned a thick purple-black color, which looked extremely permeating.

The injuries on the entirety of his body, the congestion, and the tearing of the fascia caused by the damage to the capillaries, surpassed the magical abilities of the psychic energy water, which had limited effect on his wounds at this time.

To recover, he could only rely on time to “heal” these terrible wounds.

“Give me some strength, system. I’ve been working so hard, if there are not enough survival points, how can I soothe my wounds!”

Su Mo fetched some psychic energy water and applied it to the wounds to accelerate the recovery of the injuries as he walked over to the lower floor while limping.

The small thermal weapon machine was temporarily placed on the third floor of the shelter, together with the workbench; one horizontally and the other vertically.

Su Mo tried to put the hard-won laser tool into the vacant groove on the top of the machine and found that it fit perfectly. Sitting on the bench, Su Mo quietly waited for the arrival of eight o’clock.

Every morning, there would be a baptism of system announcements, and today was no exception.

Time passed in minutes and seconds and, at eight o’clock, the system’s prompt notification arrived as scheduled.

[Doomsday Calendar Month 1, Day 18]

[Scanning host survival environment. Survival points evaluation in progress. 308 survival points gained today.]

…

Total calculation: Survival points +1798

Survival points remaining: 2352

“Great! I knew that, since it was such a dangerous situation, the survival points reward would naturally be substantial as well.”

Looking at the survival points given by the system, Su Mo was pleasantly surprised. Supporting his body with one hand on the table, he stood up and walked over to the thermal weapon machine.

He had more than two thousand survival points again and, so long as he splurged it on the shelter, it would continue developing rapidly.

However, his main focus now was undoubtedly…

The small thermal weapon machine!

Standing in front of the dilapidated, unrecognizable machine, Su Mo focused his thoughts and looked for the upgrade method.

[Small thermal weapon laser manufacturing machine (Extremely Damaged)]

[Description: A small thermal weapon laser manufacturing machine with a variety of functions such as cutting, casting, forging, welding, stamping, extrusion, laser forming, computer control, one-time molding, and quality assurance. Currently lacks a laser tool, central control computer, and has sustained significant damage to the circuit board.]

[Upgrade directions: Restoration (3380-2600), Upgrade (960), Efficiency (350), Material (1210)…]

The overall upgrade price was too high but, this time, the system was very considerate and did not give the overall upgrade method, but instead listed it separately.

Su Mo looked for whatever materials he still had in the warehouse and input all the items that could be added, and the reduction amount increased again, reaching 2900 points.

“I choose to restore it!”

When he saw that other items could no longer reduce the cost, Su Mo focused mentally and selected the restoration upgrade direction!

The shining green light once again scattered from his body, covering the large pool of objects at his feet and, at the same time, the laser tool was picked up and hovered in the air.

As the green light covered the iron surface of the broken machine, more and more rust fell off, merging into the green light, and increasing its momentum.

Gradually, the “true” face of the machine had finally begun to take shape under the restoration process!

The machine was not large, only about the size of two workbenches, and its entire structure was black-gray, exuding a cold light.

After being polished by the system, the parts were now shiny silver, as if they had come out of the factory brand new.

“It’s done!”

Seeing the green light retract, Su Mo could no longer contain the excitement in his heart. After connecting the machine’s circuit to the power socket, a small computer similar to the selection screen of the machine popped out.

Compared with the workbench, the small computer was better, and its functions also confirmed this.

“The central control computer is damaged. Even with the restoration of the system, the designs of the firearms made by Magoo cannot be retrieved. It is a pity.”

Although Su Mo was mentally prepared for this before the restoration, when he saw the empty design section displayed on the small computer, he was still a little disappointed.

However, the disappointment was immediately wiped out after he automatically imported the design blueprints from the treasure chests.

As long as there was a weapon design blueprint, every series of the corresponding 5.56 bullet design blueprint specifications could be manufactured.

In other words, if the firearms required two different specifications, M193 and M855, as long as the weapon required it, and it had obtained the original design blueprint, it could be directly manufactured.

“Not bad. A single bullet design blueprint can solve all the subsequent adaptation problems. This is truly a praiseworthy function!”

Nodding his head, Su Mo looked at the manufacturing specifications of the M-1 rifle again.

During Earth’s era, manufacturing a gun required a lot of technology. Unless one had access to the equipment in a military factory, it was difficult for ordinary people to buy a suitable “seamless” steel pipe.

Ordinary steel could not be used to make a gun barrel because it had to withstand the pressure generated by thousands of repeated gunpowder explosions. It would be subjected to the friction of the bullet and, at the same time, it had to withstand the ablation of the propellant. It was not something an ordinary steel pipe could withstand.

Therefore, it had to have a degree of hardness but, if it was too hard, the steel would be brittle and easily break. Therefore, in addition to hardness, there also had to be toughness, which is what we call yield strength.

On the thermal weapon laser manufacturing machine, the steps to manufacture guns had been greatly reduced. Only certain amounts of steel, iron, and copper could be used to produce ordinary quality guns which could guarantee at least thousands of stable shots.

On top of that, to improve the quality of firearms, one had to either choose to upgrade the level of the machine or invest in high-quality materials such as high-end engineering plastics.

After seeing that the Type-80 machine gun also needed these materials, Su Mo could only calm his restless heart.

“There is no iron or copper in the shelter, so it seems like I am stuck at a bottleneck. I must find a way to source those materials quickly, otherwise, I will end up having to trade a lot of materials for them, which is not cost-effective!”

After calculating in his mind, Su Mo quickly sorted out the current resource dilemma faced by the shelter.

The three most important basic resources in the wasteland: oil, iron, and copper.

At present, he had obtained one. As long as Su Mo got his hands on the next two, he could switch from bicycles to high-speed trains, and would no longer need to risk being controlled by others.

“Why don’t I try to use all the duplication coupons on the resource card? All at once?”

As soon as this crazy idea appeared, Su Mo’s heart jumped suddenly, looking at the cards floating in the storage space.

The next moment, all the cards that had been opened from the treasure chests all bounced out of the storage space and began to float in the air.
