My Post-Apocalyptic Shelter Levels Up Infinitely!

Chapter 78: Super Ace, Upgrading The Main Door!

Su Mo could not suppress the wave of dizziness that he got when looking at the design of the camouflage, along with the incomparably large missile.

With a killing machine like this, even if a giant dragon appeared today, it would be struck down in minutes, much less some kobolds.

‘I’ve been a part of so many prize draws on earth and always received a bunch of junk. I never thought that my luck would increase day by day after coming to the wasteland!’

Su Mo, feeling very excited at heart, actually wanted a powerful creature to appear right now so that he could pull out the Dongfeng Missile and aim it at the creature.

As the cards were all completely flipped over, the other cards gradually hid within the item creation system. The prize draw page receded and the system returned to the functional interface.

This time, however, an extra card appeared in the creation function’s storage. As Su Mo examined it, the properties appeared alongside it.

[Trial Use: DF-17 Ballistic Missile Truck (Rare)]

[Description: The missile truck carries a tactical waverider hypersonic near-space missile equipped with a hypersonic warhead. It is an all-weather, glide-boosted hypersonic weapon with excellent penetrative power that can accurately strike mid- and short-range targets.]

[Special Ability: Baby Please Turn Back: Using this item will provide the host with 10S of map clarity. Wherever the host has previously set foot can be loaded into the map to manually aim and attack.]

[Missile Speed: Unpowered high-speed flight: 12,359km/hour (Mach 10); Gliding speed from the atmosphere: 24,758km/hour (Mach 20)]

[Operational range: 2800 km]

[Precision: 1.86m]

[Comment: One of the legendary beast River Crab’s favorite weapons—please use with caution!]

Glancing at the Trial Use at the top of the card, a message popped out after tapping it mentally.

“So it’s just a single-use item. I thought that the missile truck would be left behind for me to use after shooting it,” Su Mo grinded his teeth and said unhappily.

Leaving aside the fact that the missile was a great killing machine, even just the missile truck would have been an invincible existence in the current environment.

With the strong force exerted from its 10 tires, just a little tweaking would make it a moving bug-like existence.

“Still, humans shouldn’t be too greedy anyway. With this weapon, if there’s any ‘thing’ that dares to provoke me within at least 2500 kilometers, I’ll let you know the true meaning of the word ‘suffering’!”

The camouflaged ace card brought him great confidence.

‘Whether it was a cow ghost or snake god, or even a mythical giant dragon, I’ll send over a DF-17 and we’ll see!’

With this killing machine, Su Mo instantly felt ten feet taller in this doomsday world!

Forcefully turning off the system interface, Su Mo strived to not think of the creation tab, and his emotions gradually calmed down.

He walked into the supplies room and took out the leftover Dalieba bread that had not been eaten. He sliced off enough pieces to feed a few people and placed them into the wok.

After adding in a few spoonfuls of psychic energy water, he waited for the water temperature to rise while the fire was burning under the wok.

Opening the private message channel he used as a diary, Su Mo sat on the stone bench and started dictating, “Today is the ninth day in the wasteland. Okay, I’ll admit I was indeed a little arrogant.

“However! I’m progressing very quickly. Soon enough I’ll have TNT, and I’ve even obtained a super amazing ‘killing machine’—hehe, I’ll keep that a secret for now.

“It’s time to start up the oil well in shelter number two too. I’m very much looking forward to whether the high-quality oil will have any strange abilities. Still, this isn’t an issue either. I’ve already obtained the complete extraction process—I’ll just have to put some effort into it.

“Every time I leave the shelter, it’s a constant worry that the shelter’s backdoor is unlocked. It won’t be good if anyone sneaks in. Luckily, I received some ‘rewards’ today—it’s time to upgrade the main door!

“Oh, right… I should also move the good stuff back from shelter number two. Just leaving it there doesn’t feel too safe!”

Gloop gloop…

Seeing the water in the wok starting to boil, Su Mo turned off the private message channel and took out today’s meal.

It was very simple, but at the same time also very lavish.

Nuts, raisins, and crushed peanuts floated atop the bread soup.

The broth was rich and the taste was luscious.

He brought over Oreo, Big Spark and Little Spark’s food bowls. After pouring in a decent amount, he poured the rest into his own bowl and a simple breakfast was completed.

After finishing breakfast, Su Mo went to the weapon armament storage and began to arm himself.

His outerwear had not dried yet, so he could only throw on his raincoat to make do for the moment before putting his armor on.

Opening the shelter’s inner door, Su Mo walked along the passageway to reach the outermost main door, his thoughts in constant motion.

[Shelter’s Stone Door]

Description: A door made from sturdy stone. After setting the bars in place, it is indestructible and uncommonly safe.

First Upgrade Option: Upgrade the main door material, change the model of the stone main door, add new locks, and increase its safety and practicality. Survival points required (220).

Second Upgrade Option: Change the size of the main door, strengthen the main door material, add vertical apertures to shoot from, and increase malleability and combat ability. Survival points required (240).

“The price isn’t expensive, but the shelter door’s material is already tough enough. There’s no need to spend on improving this aspect.”

Shaking his head, Su Mo mentally focused and requested the system to provide different upgrade options.

[Shelter’s Stone Door]

Description: A door made from sturdy stone. After setting the bars in place, it is indestructible and uncommonly safe.

Upgrade: Material (180), Model (60), Size (35-600), Independent functions (20-600)… Iron mechanical rotary lock (70)…

“Yes! I want a combination lock like this that can open and lock itself mechanically—it’s very practical and won’t malfunction easily!”

Su Mo clapped and sighed lightly, his face full of satisfaction.

Considering the doomsday situation, especially for this kind of door, the older the machinery, the higher the practicality.

On the contrary, a lock with fancy bells and whistles like the fingerprint recognition system and regular key locks were not all that reliable.

A mechanical rotary lock like this was far more reliable!

Returning to the storage area, Su Mo started picking up pieces of iron.

Thanks to his previous acquisitions, he currently owned about ten pieces. When piled up together, they looked a little like an iron wall.

He headed back to the main door. After inputting four pieces of iron, the price of the mechanical rotary lock decreased to 35 points and did not change when he added further pieces.

He quietly uttered, “Upgrade.”

Green light shone and the iron pieces on the ground floated into the air simultaneously, turning them into pieces of red-hot molten iron.

Illuminated by the green light, the molten iron stuck to the surface of the stone door seamlessly, looking as if it had naturally grown on the stone.

A few seconds later, the green light faded.

A new lock for the shelter door had been successfully created!

“The first password is seven 0s. Uh-huh… I’ll change it to 7355600 then. With such a complicated password, even if someone wanted to decipher it manually, it would take them at least half a day.”

Even if a locksmith came over, it would be very difficult for them to decipher it within a short period of time.

He set the password and pushed the bolt back in. Su Mo then opened the shelter door and went outside of the shelter.

The wasteland sun had not completely warmed up the early morning air.

Waves of cold billowed with the wind, kicking up sand over the ground.

After checking that there were no abnormalities in the surrounding area, Su Mo cast aside his worries and closed the door, before trying to open and close it.

First, he tried closing it.

As long as the password was correctly input, he could turn the wheel until the bolt was in place. When the wheel could no longer be turned, that meant it was successfully locked.

If the password was messed up, the wheel could not be turned.

When all of the codes were correct, then the wheel could then be turned back to open the bolt.

“Alright! I’m a lot more relieved now. At the very least, I don’t have to go through the trouble of entering and exiting through the backdoor!”

Evaluating his own masterpiece, Su Mo tried it another two times to determine that there were no issues before walking along the hills toward the backdoor area.

Su Mo had his own ideas for this backdoor.

He summoned the system and examined the backdoor. At Su Mo’s command, five survival points were deducted.

The backdoor that had previously been accessible was now sealed, becoming completely one with the ground without a trace of a seam.

“For this backdoor, if there’s a need to use it, it would definitely be when danger arrives. When that time comes, even if I have to spend five more survival points to open it, it would be worth it. I’ll leave it sealed on normal occasions and leave it as a hidden ace!”

After opening the front door to return to the shelter, Su Mo started packing up the things he wanted to bring along when he went out.

It was time to harvest a round of the ‘wealth’ in shelter number two as well!
