My Post-Apocalyptic Shelter Levels Up Infinitely!

"MMP!"

"The quality of this door is really good!"

Continuing to **** carefully on the door for a while, Li Hu couldn't help cursing after realizing that there was no place for people to start on the whole door.

From the results of observation from the outside, there is no button that can be opened or closed on the entire black metal door that is 2.7 meters high and 2.4 meters wide, and there is no place where a key can be inserted into a traditional keyhole.

It looked like a wall, with no place for anyone to attack.

To be honest, if someone told Li Hu that there would be a genius to make the gate like this before seeing this door, he would never believe it.

A building, with its entrance and exit doors, how could someone be so stupid that they don't even leave a place to insert a key!

Does it really depend on the mechanical structure of the energy supply to open and close?

What if there is a power outage?

What if the mechanical structure is damaged?

Any kind of accident may cause the door to become a dead thing, and there is no other way to open it except to destroy it.

Is it possible to destroy it if it can't be opened?

Under all kinds of questions, Li Hu was very puzzled.

But now, the task is on oneself, no matter how outrageous it is, how to open it has become the first level for everyone to enter.

"Try to blast?"

Looking up and down the whole building, Li Hu pondered in his heart, and did not dare to give this order directly.

In terms of architecture, even if he is a layman, he knows the basics of force points and load-bearing columns.

Once the gate is one of the stress points of the whole building, if you choose to blast it, it is very likely that the building will collapse directly after the gate is opened.

At that time, it would be fine if there were enemies inside, and Quan Dang had solved the opponent in advance, and he, the commander, would happily share all the credit.

But if it is full of high-value things, it is a reward awarded by the game to its own director.

It was only because the director was temporarily outside that he could not notify the territory information.

When it collapsed like this, let's not say that Chen Shen, the old miser, had to cry to death inside.

He Li Hu, as the commander, had to be punished for his unfavorable performance no matter what, and was gradually beaten and marginalized in the cold palace.

Inappropriate, inappropriate.

"In that case..."

After analyzing the pros and cons of several attacking methods in his mind for a while, and then turning his head to look at the defensive circle that was guarding one kilometer away, Li Hu made a decision on the spot.

"Technical team, let me go first and see if you can get him out of my way gently!"

The voice fell.

The warriors who had been grinding their fists long ago, four of them walked out at that time.

These four people are not young, all of them are in their early forties and unshaven.

They are all manufacturing talents specially selected by Soma when selecting talents in the Tundra fleet at that time.

Even the last one has been immersed in this industry for more than ten years, and he has clicked almost all the technical points and rated it as A-level.

And the strongest one has been working for more than 20 years and is a well-deserved S-level talent.

It is only because the manufacturing industry in the depression is still at zero basis that its rating is only A, and it does not enjoy the best benefits!

"Captain, you step back first and let me, Lao Liu, try the level of this thing!"

When he got the opportunity to perform, the man named Liu Cheng excitedly rubbed his palms and brought the three people behind him forward.

There is no door where you can start, although it is difficult to defeat Li Hu, but for those of them who have long been used to it.

It's a problem, but it's not a big problem!

After putting down the tools temporarily rented from Lu Kuan's laboratory for scanning and testing, the four had a clear division of labor and quickly started the first wave of tests.

The first is the thickness of the entire door, which is best solved.

First connect the scanning tool to the portable power supply, and after turning it on, stick a few tentacles for detection tightly around the door.

With a regular resonant wave, the entire door, from the perspective of naked eye observation, although still unchanged, actually began to tremble from a microscopic perspective.

Just relying on this trembling, very easily, the instrument gives a data that is accurate to two decimal places!

"4.15 meters, good guy, the person who made this door is really willing to pay for it"

"Such a thick door, even a sandwich iron, can resist the power of a small equivalent of TNT!"

As Liu Cheng read out the data on the instrument with a look of amazement, the four of them looked at each other, and they were able to read each other's minds.

When the tools and instruments in the civilized era are complete, this thickness is naturally not difficult.

Whether it is to chemically corrode the key position, let it break rigidly, so that it can be opened by external forces.

Or start with the way of opening the door, forging the corresponding authentication point outside, you can open the door calmly, without any effort.

But unfortunately, the current situation is not the earth, but the wasteland!

Detecting this thickness, excluding some methods that cannot be used, there are not many ways for everyone to try!

After discussing it internally for a while and reaching a unified opinion, Liu Cheng pondered for a while.

In the end, he chose to stand up and came to Li Hu's side.

"Captain, maybe we need to damage this door and do an experiment."

"Oh?"

The enemy of the enemy is the friend.

This door now seems to be blocking everyone and protecting the secrets inside, making people a little helpless.

But correspondingly, as long as the building can be won, the door will in turn become "one's own person".

Think it's sturdy, durable.

As long as you hide in danger, the effect is comparable to hiding in an underground fortress!

However, there is still a premise.

At least you have to go in before you can think about how you will use it later. If you are blocked from the door, it will be useless to say anything.

After thinking about this, Li Hu was slightly taken aback, and finally nodded in agreement.

With the answer, Liucheng returned to the front door and began to greet the other three to take out all kinds of bottles and jars from the box.

These things are all the solutions of the four people who have nothing to play in their spare time.

Red, green, blue, purple.

As several different colors began to mix into one of the bottles, under Liu Cheng's shaking, a jet black like ink began to spin out from the center, and then soaked the entire solution.

"It's done!"

Shaking for a full five minutes, I waited until all the pitch black appeared and disappeared, and finally transformed into a colorless and transparent solution.

Liu Cheng sighed in excitement and stopped.

At this time, a full half an hour had passed since three o'clock, and the sky began to suddenly turn towards dusk.

Not daring to have any delay, holding the solution in hand, Liu Cheng immediately strode forward and began to carefully dump it on the lower right corner of the gate.

hiss...

A colorless, odorless solution that looks harmless to humans and animals.

In fact, the moment it touched the door, it was like sulfuric acid corroding white paper, and a burning smell suddenly erupted.

In an instant, the lower right corner of the door began to change color, and then there were countless holes that made the intensive phobia look like it was going to happen on the spot.

"Change the A-3-552 solution!"

Looking down for a while, Liu Cheng shook his head in dissatisfaction, and quickly ordered the three people in the back to continue the deployment.

Although the solution just now can corrode the material that constitutes the gate, the damage is irreversible.

If you want to open it in this way, you can only make a few tons, pour it all on the door, and corrode it layer by layer.

Not realistic and not worthwhile!

A moment, five minutes passed.

Holding the newly prepared colorless solution, Liu Cheng moved to the lower left corner and continued pouring.

This time, the reaction speed of the gate material was significantly slower. Although the smell was still pungent and unpleasant, the material was finally preserved, and no large-scale collapse and corrosion occurred.

"There is a play!"

Standing up excitedly, and after a quick thought in his mind, Liu Cheng continued to order the preparation of the next new solution.

again and again.

Bottom right, bottom left, top right, top left...

After waiting until all four corners were tested, Liucheng returned to the door with confidence with the fifth solution.

This time, he did not continue to choose to experiment on the edge, but very boldly poured it all on the left side of the center of the gate!

Whoa!

Whoa!

The moment the solution and the black material came into contact, countless white gas began to evaporate, bringing out a dream-like fragrance.

Visible to the naked eye, the black on the surface of the door began to fade quickly, gradually turning into a faint silvery white.

And the silver-white color didn't last long, and finally settled down with a white color that was incompatible with the surrounding area.

"It's done!"

Before waiting for the high temperature that erupted on the surface of the gate to subside, Liu Cheng excitedly picked up the scraper he carried with him and tapped it lightly on the white surface.

Like scraping away mud, layers of white began to be carried off.

Finally, a...

New window!

"This is the lock on this door!"

Relying on the detector, the general structure of the inside of the gate is detected, and the location of the "lock cylinder" is determined.

The protection above the lock cylinder is corroded layer by layer through the solution, revealing the lower entrance where the key can be "inserted".

Liucheng's plan was exceptionally successful!

At the same time, looking at the style of the lock, he unconsciously got a new message in his mind.

"Captain, this door, no, this building, I have a 99% probability that it is from the hands of us humans"

"We are so familiar with this structural design that I have even participated in similar projects!"

After calling Li Hu excitedly behind, Liu Cheng gave the information he got.

Inside the window is a mechanical lock that looks extremely complicated.

From left to right, there are a total of twelve scroll wheels, with incomprehensible unknown symbols on them.

Just above the roller is a copper piston that can be pressed.

Opening such a lock is very simple.

Just place the twelve rollers in the appropriate position, press the piston, and the mechanism inside will automatically fail.

At the same time of failure, the lock plate placed inside will also start to function, pulling up or pushing the entire door back to make room for entry and exit.

This method is very retro, but extremely reliable.

There is no need to rely on any facilities that require energy, and there are no reliability issues.

The only tricky part is...

"I even know how to make this lock!"

"But it doesn't mean that I can crack it, because he has only three input opportunities. If it exceeds three times, the interior will be locked forever!"

Trying to turn the scroll wheel, feeling the smooth damping it brings, Liu Cheng's expression was solemn.

"Are you sure this lock was made by us humans?"

Liu Cheng nodded heavily: "I'm 100% sure, Captain, look, there's even a sign of the owner's identity here!"

Taking out the rag in the tool bag on his waist, Liu Cheng carefully wiped the lubricating oil on the copper piston.

As the black stains faded, the so-called owner identification began to gradually emerge at the circle of the cylindrical plug.

Liu Cheng is no stranger to this logo, nor is Li Hu.

It is the combination of uppercase and lowercase letters in English!

Tilt his head, Li Hu began to read out each word in sequence in confusion.

"A..."

"S..."

"M..."

"L..."

"mmd..."

"Huh? What does that mean?" 1

...

At the foot of Wuzhi Mountain, the sun sets in the west.

It was already early seven o'clock in the evening, and with the last rays of the sunset, Feng Mengyue, who was with the villagers of Shanyue in their early 300s, finally arrived late.

The two soldiers who were left at the temporary camp by Soma and used to meet them heard the movement from afar.

At this time, seeing the team coming from a high place, both of them shook their heads calmly.

It's completely different from the escorts who are always on the move.

The people Feng Mengyue brought were very amateur, and most of them were even chatting and laughing on the road, as if they were out for an outing.

This difference is not small.

On the other side, after walking through the high slope, Feng Mengyue also saw the soldiers who stayed here and waited, as well as the traces left by the temporary camp not far away.

"Hey, has God Su left?"

One of the two warriors who stayed on the spot walked out and said with a smile: "Lord Wind, our director has been taking people away for three or four hours. At this time, I am afraid that they will all start to contact the two territories on Wuzhi Mountain. ”

"So fast?"

Looking at the scattered footprints on the snow in surprise, Feng Mengyue muttered in her heart, but her mouth was not slow:

"I heard that God Su found a small treasure here. There are quite a lot of things in it. Can you take it with me?"

The soldier smiled and continued to nod: "Yes, you come with me!"

After that, UU read www.uukanshu. Com did not give Feng Mengyue a chance to continue asking, so the two of them turned around decisively and led the way forward.

Seeing this, Feng Mengyue was stunned for a moment, and she couldn't help but feel a little dissatisfied.

When facing Suma, no matter what kind of behavior Suma makes, it is friendly or disdainful.

Feng Mengyue will naturally accept it.

After all, this is the human **** Su.

But in the face of these ordinary warriors under Su Mo, Feng Mengyue pretended that she was once the lord of the territory of thousands of people.

Being so neglected and disrespected now, the clay figurine is still a little angry!

"I want to see how many supplies there are to make you so awesome!"

With a cold snort in her heart, the smile on Feng Mengyue's face subsided, and an aura naturally emanated.

Feeling the emotions of their lord fluctuate, the Shanyue villagers who followed behind gradually stopped chatting, closed their mouths and covered their heads and drove on.

For a time, except for the common sound of falling down from time to time because of the slippery snow, the atmosphere of the entire team was extremely dull.

"Lord Wind, the front is where our supplies are stored."

"When you return at night, the mountain road is dangerous. Our director specially explained it. Please be careful when you return!"

Turning over a **** again, the two warriors stopped and turned around with smiles on their faces.

Reach out and don't hit the smiling man.

With the anger still in her heart, Feng Mengyue had no choice but to nod her head stiffly, and climbed the **** after taking the last few steps.

Following the direction of the soldier's finger, she looked at it for the first time.

And this look.

Feng Mengyue actually froze in place, her face full of incredible expressions!

"This is!"
