My Post-Apocalyptic Shelter Levels Up Infinitely!

Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation

It was known that the energy released by the explosion of one ton of TNT was about 4183 megajoules.

Effective kill radius = C*explosion equivalent”1/3.

‘The C in this equation represents the proportionality constant, which is generally taken to be 1.493885.

According to this equation, when one million tons of TNT exploded, the effective kill radius would reach a horrifying seven kilometers!

Not to mention that its effective fragmentation area would also be an appalling one hundred and fifty square kilometers!

Humans had found it extremely difficult to control such a terrifyingly destructive weapon after its invention.

Even in theory, the person who invented this weapon would not have been able to create a “shield” strong enough to resist the damage of this weapon.

Humans still needed to rely on the power of the Earth itself. They hid inside the mountains, underwater, or even underground, just to shield themselves from the destructive power of this weapon.

However, after looking at the gate in front of him, Su Mo’s eyes lit up!

Inadvertently, he had found something that humankind had been searching long and hard for.

A’ shield”!

“For the time being, I can only see that the expeditionary army has studied the use of materials very extensively. The specific details will have to wait until I enter the room and scan my surroundings.”

“As for the secret key and password needed to open this gate… I can only give it a try.”

After reading the information displayed on the panel a few more times, Su Mo’s heart settled down. He reached for the map that was wrapped in the mysterious protective bubble and brought it over.

The next second, when the map approached the gate, a weak suction force emerged.

A gap opened in the silver-white alloy gate out of thin air that sucked the map inside completely.

Wow!

Without the map, the ocean turned pitch black again.

Just as Su Mo was about to pull out a light stick and continue his search, the entire door suddenly lit up with a bright light, as if activated by some switch.

Miraculously, the light was not blinding, but was extremely soft instead, giving people the impression that they had just arrived home.

Rumble.

Aseries of vibrations came from the bottom of the ocean. Despite being five thousand meters underwater, and under thousands of tons of high water pressure, this series of vibrations was slow, but extremely steady.

“Hello, this is the Captain of the 13th Army, Su Deben.”

“This is the Super Vision Eye Satellite Base, the site of the Nine-four-five Plan.”

“It was detected that you have successfully put in the corresponding secret key. Please follow the hints on the secret key and key in the correct password.”

“You have three chances. After the three chances are used up, the gate will be locked for thirty days!”

‘When Su Deben had left this secret trump card behind back then, he probably guessed that the Expeditionary Army would not be able to make it here to carry on his legacy.

Considering the importance of this base, he did not set any self-destruct conditions, and only made it so that the gate would be locked for thirty days.

Ina sense, this was an expression of goodwill.

Su Deben left an opportunity for other players to enter the base and inherit his legacy!

“Password.”

“The map did not say anything about a password though. Is the password the time they arrived at the wasteland during Year 992″

‘A panel popped up on the gate for Su Mo to key in numbers.

For his first chance, Su Mo thought about it for a moment and finally keyed in the numbers provided in Magoo’s diary that pertained to the Expeditionary Army’s time of entry into the wasteland.

Sizzle.

He failed!

Obviously, that was not the correct password.

“Tch, this is troublesome. If there’s really a password specifically for this gate, I definitely won’t know it. I’ll have to try something else.”

It would only take three thousand survival points for Su Mo to corrode the gate and enter.

Su Mo did not panic despite only having two chances remaining but, once again, he calmly keyed in a password.

This password was based on the number of words in each paragraph on the map. There were exactly eight paragraphs, which meant that there would be eight corresponding numbers.

However, it turned out that Su Mo was still overthinking things this time.

With a sizzling sound, Su Mo failed once again. He had only one last chance left.

“Does this mean that there is no corresponding password stored on this secret key? However, this Su Deben clearly said that there is one…”

“Wait…”

Su Mo was recalling what was recorded on the map from start to end. A seemingly ordinary, but not negligible point leapt into his mind.

‘The next second, no further attempts were made to test other codes.

Su Mo asked Oreo to open the protective bubble, after which he took out a knife for cutting vegetables from his storage space and tried to slice a small wound on his pinky finger.

Scrape scrape

After he received the attribute bonus, his skin had become extremely sturdy. He could only cut white lines on his skin despite trying multiple times.

‘These white marks would quickly disappear if he did not apply more force onto them immediately.

Luckily, after repeatedly slicing for 20 or 30 seconds, a droplet of blood was finally squeezed out from a tiny cut, staining his fingertips.

“If I’m not getting it wrong…”

After thinking in silence, Su Mo looked at the input device in front of him that required a password. Without hesitation, he directly pressed the drop of blood onto the confirmation button.

Whew.

Although Su Mo had not keyed in anything at all, and this input device was only an ordinary electronic device, the drop of blood disappeared instantly when Su Mo’s fingertips touched the confirmation button, as if it had been taken away.

The confirmation button, which was beige in color, also displayed one scarlet word.

Success!

In Su Mo’s line of sight, eight digits slowly began to float up into the input device screen.

One after another, as if analyzing the composition of the drop of blood, the color of the confirmation button would lighten as each number lit up.

‘When four digits had lit up, the red color became blurry.

Fearing that the drop of blood was not enough, Su Mo continued cutting himself immediately, and once again coated his fingers with some blood.

The analysis progressed much faster this time. In just under twenty seconds, the last four digits were all lit up.

“password has been keyed in correctly. I’m glad to meet one of my kind in such a situation. Please tell me your name and your identity.”

A pleasant notification prompt sounded.

‘Who knew how long ago and how far away their parallel universe was, but now they had been linked to Su Mo’s thanks to a little blood!

With a crack, a light green aura lit up, and the gate opened steadily, even though it was five thousand meters underwater.

Su Mo did not manage to answer the question, as seawater rushed inside through the open gate. Su Mo called Oreo over, and they entered through the narrow entrance.

As if the gate had magically sensed Su Mo entering, it began to slowly close.

There was a rumbling sound of water being pumped out and, soon, more than two-thirds of the accumulated seawater inside the room had receded.

When Su Mo felt his body lighten, he realized that.

He was standing on a steel floor with his feet on the ground!

“Welcome, fellow human being from Earth. Please tell me your name and your identity.”

The AI repeated itself, seemingly devoid of emotions.

This time, Su Mo did not hesitate and said aloud, “I’m Su Mo, an ordinary office worker!”

‘As the words echoed, the passage fell silent once more.

As the AI processed his identity, Su Mo began to carefully survey the interior of the passage that was illuminated by light.

Unlike the high-tech look of the gate outside, all the facilities inside could be considered fairly normal.

Although the level of technology was certainly much more advanced compared to the technology in Year 99 on Earth, at least from where Su Mo came from, it was still within the realm of human understanding.

In the room, there was no high-end “foreign” equipment that looked advanced or futuristic.

“Oh? Su Mo, your identity is very special.”

“According to my database, an ordinary office worker should not be able to find this place.”

“However, your body signals tell me that you are not lying.”

“Excuse me, can you briefly describe your intentions in coming to the Super Vision Eye Satellite Base?”

The voice spoke once again.

This time, Su Mo did not answer honestly. He shook his head at the camera in the corner.

“Won’t you invite me in? Standing outside and talking is not the Huaxian way of hospitality.”

“Um…You’re right! Please come in!”

“Please forgive me for being direct. You are the only living creature I have seen in over 3,700 years and, miraculously, you also have a 91.35% genetic similarity to our leader, Su Deben. According to biological ancestry, the two of you must be very closely related.”

“Of course, I am not saying that the leader, Su Deben, is part of your family. I’m merely analyzing the relationship between the two of you from an objective point of view.”

“You can call me Little Ai. Ai as in “artificial intelligence”.”

Su Mo had a lot of experience dealing with programs.

‘When faced with this kind of “artificial intelligence” with established conditions of judgment, Su Mo counteracted the situation efficiently and regained the upper hand.

As Little Ai opened the door on the inside of the passage, it rambled on and on like an old aunty.

“Oh?”

“Su Deben and J are related. This is not strange at all. We both have the same last name, Su. We may have had the same ancestor dozens of generations ago!!”

Su Mo sounded like he was joking, but his body was constantly on edge as he walked with Oreo in tow.

Luckily, nothing attacked as Su Mo walked all the way down the passage through the gate, and entered the second section of the passage.

The road into the mountain was not straight. The passage alone had as many twists and turns as a ball of yarn.

This design allowed for segmental defense when faced with an enemy attack. It also ensured the maximum and absolute safety of the main center.

However, those who had to walk this path would find the experience extremely unfriendly!

It took Su Mo five minutes to dive down five thousand kilometers underwater from the surface of the ocean and reach this base.

However, he had walked through seven gates and eight passages in the span of ten minutes since he arrived at the main entrance.

After arriving here, the end of the passage was still not in sight. It was quite a despairing sight.

“Dear Little Ai, how long is this passage? How about you open all the doors so that I can move faster?”

Little Ai: “Huh, dear Little Ai? That’s a good name, I like it.”

“Mtr, Su Mo, there are still 2.8 kilometers until you reach the main section of our base. We have constructed a nine kilometer-long circling corridor in our base. It can effectively resist more than 99.9% of enemy invasions. It’s a masterpiece designed by architectural expert, Mr. Kang Hui. Relying on this

defensive measure, we can use a variety of weapons that we have already set up to defend ourselves. This is to ensure an absolute sense of security.”

Little Ai’s voice could be heard everywhere.

In this base, every speaker and every camera was under its control.

Hearing that only the final two kilometers or so remained, Su Mo immediately accelerated his pace.

Another three to five minutes passed. When Su Mo’s sight was no longer hindered by the circular passage, he could see that the core section of the base was finally.

Inclear sight!
