My Post-Apocalyptic Shelter Levels Up Infinitely! Chapter 627: Open the door for the first time, 7 letters on the copper pillar!

  Chapter 630 Open the door for the first time, the seven letters on the copper pillar!

   "MMP!"

  "The quality of this door is really good!"

  Continue to **** carefully on the gate for a while, and when he finds that there is not even a place for people to attack, Li Hu can't help but curse.

  From the observation results from the outside, the entire black metal gate, which is 2.7 meters high and 2.4 meters wide, does not have any buttons that can be opened and closed, and there is no place where a key can be inserted into a traditional lock hole.

  It looks like a wall, there is no place for people to start.

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

  A building, its entrance and exit door, how could someone be so stupid as to not even leave a place to insert a key!

   Could it really be opened and closed by the mechanical structure of the energy supply?

  What if the power goes out?

  What if the mechanical structure is damaged?

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

  Could it be possible to destroy it if it cannot be opened?

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

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

  "Try blasting?"

  Looking up and down the whole building, Li Hu pondered in his heart, but he didn't dare to give this order directly.

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

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

  When the time comes, it's okay that there are enemies inside, and it's right to deal with the opponent ahead of time, and he, the commander, happily shares all the credit.

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

  It’s just because the director is temporarily outside and cannot notify the territory information.

  Then such a collapse, not to mention Chen Shen, an old miser, would cry to death inside.

  As the commander, he, Li Hu, had to bear a punishment of being unfavorable in his work, and was gradually beaten to the sidelines in the cold palace.

  Not right, not right.

  "In this case."

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

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

  The voice falls.

  Four of the fighters who had been working hard behind them walked out at that time.

  These four people are not young, all in their early forties, with unshaven beards.

  In particular, they were manufacturing talents specially selected by Sumo when he was selecting talents in the tundra fleet.

  Even if it is the last one, it has been immersed in this industry for more than ten years, and almost all the technical points of its body have been checked, and it is rated as A-.

  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 foundation that its rating is only at A level, and it does not enjoy the best benefits!

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

   Got the opportunity to perform, and the first man named Liu Cheng rubbed his palms together excitedly, leading the three people behind him forward.

  There is nowhere to strike. Although it is rare to defeat Li Hu, it is commonplace for them.

   is a problem, but not a big problem!

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

  First of all, it is the thickness of the whole door, which is the best solution.

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

  With a burst of regular resonant waves, the entire door, viewed from the perspective of naked eyes, remained unchanged, but actually began to tremble from a microscopic perspective.

   Only relying on this point to tremble, it was very easy, and the instrument gave a data that was accurate to two decimal places!

  "4.15 meters, good guy, the person who made this door is really willing to spend money"

  "Such a thick gate, even with sandwich iron, can still resist the power of a small equivalent of tnt!"

  Following Liucheng 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 mind.

  In the age of civilization, when the tools and instruments 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 force.

  Start from the way of opening the door, forge the corresponding authentication point outside, and you can open the door calmly without any effort.

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

  Detecting this thickness, eliminating some unusable methods, leaving everyone to try, there are not many ways!

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

  Finally, he chose to stand up and came to Li Hu's side.

  "Captain, maybe we need to damage this door and do some experiments"

  "Oh?"

  The enemy of your enemy is your friend.

  This door now seems to block everyone and protect the secrets inside, making people a little helpless.

  But correspondingly, as long as this building can be taken down, this door will in turn become "one of our own".

  Think about how strong and durable it is.

  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 to think about how to use them later. If you are blocked outside, it is useless to say anything.

  Thinking about this point clearly, Li Hu was slightly taken aback, and finally nodded in agreement.

   Obtained the consent, Liu Cheng returned to the gate, and began to greet the other three people to take out various bottles and cans from the box.

  These things are all kinds of solutions that the four of them have created in their spare time during this time without much room for development.

  Red, green, blue, purple.

  As several different colors began to mix into one of the bottles, under Liucheng's shaking, a stream of jet black like ink began to swirl out from the center, and then infiltrated the entire solution.

   "It's done!"

   Shaked for a full five minutes, and waited until all the jet black appeared, then disappeared, and finally transformed into a colorless and transparent solution.

  Liu Cheng secretly sighed excitedly, and stopped his movements.

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

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

  hiss.

  Colorless and odorless solution, harmless to humans and animals.

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

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

   "Change to A-3-552 solution!"

  Looked down for a while, Liu Cheng shook his head dissatisfied, and quickly ordered the three people behind to continue to deploy.

  Although the solution just now can corrode the materials that make up this door, the damage is irreversible.

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

  Unrealistic and not cost-effective!

  A moment, five minutes passed.

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

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

   "There is drama!"

   stood up excitedly, and after a quick thought, Liu Cheng continued to order a new solution to be prepared.

   again and again.

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

   Waited until the four corners were tested, and holding the fifth solution, Liu Cheng returned to the door full of confidence.

  This time, instead of continuing to experiment on the edge, he boldly dumped all of them in the middle left of the gate!

  Wow!

  Wow!

The moment  solution contacted with the black material, countless white gas began to evaporate, bringing out a dreamlike fragrance.

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

  And this silvery white didn't last long, and finally settled down to a white that didn't fit in with the surrounding area.

   "It's done!"

   Before the high temperature that erupted on the surface of the gate subsided, Liu Cheng excitedly picked up the scraper that he carried with him, and gently pressed it against the white surface.

  As if mud was being scraped away, layers of white began to be taken down.

  Finally, a door gradually appeared.

  New window!

  "This is the lock for this door!"

  Leaning on the detector, it detects the general structure inside the gate, and determines where the "lock cylinder" is.

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

  Liucheng's plan was extremely 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 came from us humans"

  "We are so familiar with this kind of structure design, even I have participated in similar projects!"

  Called the excited Li Hu, and 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, engraved with incomprehensible unknown symbols.

   Right above the roller, there is a copper piston that can be pressed.

  The method to open such a lock is very simple.

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

When  fails, the lock plate placed inside will also start to work, pulling up or pushing the entire door back to make room for entry and exit.

  This method is very retro, but extremely reliable.

   Doesn't require any energy-hungry infrastructure or reliability issues.

  The only tricky thing is.

  "I even know how to make this lock!"

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

  Trying to turn the roller, feeling the smooth damping it brings, Liu Cheng's expression is solemn.

  "Are you sure that this lock is made by us humans?"

  Liu Cheng nodded heavily: "I'm 100% sure, captain, look, there's even an identification of the lock's owner!"

  Take out the rag from the tool bag on his waist, and Liucheng carefully wiped the lubricating oil on the copper piston.

  As the black stain faded away, the so-called identity of the owner began to gradually manifest at the circle of the cylindrical plug.

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

   is the combination of uppercase and lowercase letters in English!

   Tilting his head, Li Hu began to read out one word at a time in order in confusion.

  "A"

  "S"

  "M"

  "L"

   "mmd"

   "Huh? What does this mean?"

  At the foot of Wuzhi Mountain, the sun sets.

  It was already early seven o'clock in the evening, and after the last ray of sunset, Feng Mengyue, who was leading the villagers in Shanyue in his early 300s, finally came late.

  The two soldiers who were left by Sumo at the temporary camp to meet them heard this movement from a long distance away.

  Seeing the team approaching from a high place at this time, both of them shook their heads calmly.

  It is completely different from the strict guards during the march.

  The people brought by Fengmengyue are very amateurish, and most of them are even talking and laughing on the road, as if they are out for an outing.

  This gap is not small.

   On the other side, after walking through the high slope, Feng Mengyue also saw the soldiers waiting here, as well as the traces of the temporary camp not far away.

  "Hey, God Su has left already?"

  One of the two warriors who stayed at the spot walked out and said with a smile: "Lord Feng, our director has led people away for three or four hours. I'm afraid they will all be the same as those two soldiers on Wuzhi Mountain." The territory has begun to touch"

  "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 away?"

  Soldier smiled unabated, and continued to nod: "Yes, you come with me!"

   After finishing speaking, Feng Mengyue did not give Feng Mengyue a chance to continue asking, the two turned around decisively and led the way forward.

  Feng Mengyue was stunned watching her acting like this, and couldn't help feeling a little bit dissatisfied.

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

  Feng Mengyue will accept it naturally.

   After all, this is the human God Su.

  However, when facing these ordinary fighters under Su Mo, Feng Mengyue conceived that she was once the lord of a thousand people's territory.

  Now being so ignored and disrespected, the clay figurine is still very angry!

  "I'd like to see how many supplies there are to make you so awesome!"

  He gave a cold snort in his heart~IndoMTL.com~The smile on Feng Mengyue's face subsided, and an aura of momentum naturally emanated.

  Feeling the mood swings of his lord, the Shanyue villagers who followed gradually stopped chatting, closed their mouths and covered their heads on their way.

  For a while, apart from the common sound of falling down from time to time due to the slippery snow, the atmosphere of the whole team was extremely dull.

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

   "Returning at night, the mountain road is dangerous, our director also specifically explained, please be careful when returning!"

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

   Reach out without hitting the smiling face.

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

  Following the direction of the soldier's finger, she looked at it immediately.

  And this look.

  Feng Mengyue froze in place, her face full of disbelief!

  “This is it!”
