My Post-Apocalyptic Shelter Levels Up Infinitely!

"F*ck!

"This door sure is well-made!"

Li Hu carefully inspected the door for a while but could not help cursing out after realizing there was nowhere for them to start.

The black iron door was 2.7 meters high and 2.4 meters wide. After examining it, he found neither buttons nor a traditional keyhole that could be used to open the door.

It was like a gigantic wall with no possible way to break through it.

Before seeing it himself, Li Hu would have never believed that some maniac built a door like this.

'What kind of idiot would design a building with no entrance or exit and not even a place to insert a key?

'Is it possible that the door functions on a mechanical structure supplied by power?

'What happens if there's a power outage?

'Or what if the mechanical structure gets damaged?

'Any minor accident would make the door completely unfunctional, and there would be no other way to open it except to destroy it.

'Did they plan to destroy it if they couldn't open it anymore?'

Li Hu was puzzled, with all sorts of questions flashing through his mind.

However, no matter how outrageous the design, his task was to figure out how to get past the first obstacle for them to enter the building.

'Maybe we can try to blast it open?'

He scanned the whole building up and down and pondered about it in his heart, not confident enough to directly pass on the order.

Although a layman in architecture, Li Hu had some basic knowledge of force points and load-bearing columns.

Assuming that the door was one of the stress points of the building, it would cause the whole structure to collapse before they had a chance to enter if they decided to blast it open.

When that happens, it would be a huge success if there was an enemy inside the building, and he could happily claim the credit for getting rid of it.

However, it was also possible that the building was filled with precious items that were rewarded to the shelter leader by the game and could not notify the territory because Su Mo was outside of the territory.

Not only would Chen Shen die inside for such valuable items going to waste, Li Hu, the commander who made the decision, would surely not be able to avoid being punished for such rash actions. This failure might eventually cause him to be deemed unimportant to the territory.

'This won't do. It's too inappropriate.

'In that case…'

Li Hu carefully analyzed the pros and cons of several strategies in his mind and turned to glance at the defensive circle that was on defense a kilometer away. Immediately, he decided on the tactic they were going to approach the problem in front of them.

"Technical team. You guys check whether there is a way to open the door without causing damage!"

His voice rang out.

Four soldiers walked out of the team, eagerly waiting to attack.

The four were slightly older than the rest, probably in their early forties with unshaved beards.

They were hand-picked manufacturing talents Su Mo had chosen from the Tundra Fleet.

Even the most inexperienced one had been in the industry for more than ten years, had excellent knowledge of almost all technical points, and was rated as an A-Level talent.

The most experienced one had worked for over 20 years and was worthy of an S-Level talent.

However, the manufacturing industry in the basin was still at zero foundation, which was why he still maintained a rating of A-Level for the time being and had not received his well-deserved highest rewards!

"Captain, please take a step back for now. Let the old man test the quality of this door!"

The first man to step up was named Liu Cheng. He rubbed his palms excitedly and approached with three other men behind him after finally receiving an opportunity to showcase his skills.

Li Hu was defeated by not being able to find a breakthrough because there was no door. However, it was no big deal for those experienced and had seen all sorts of complicated mechanisms.

It was a problem but not an unsolvable problem!

They laid down the tools temporarily borrowed from Lu Kuan's laboratory for some scanning and testings of the door. The four had a clear division of work and quickly started the first round of tests.

The first was to determine the thickness of the entire door, which was the most effortless test to complete.

First, they connected the scanning device to a portable power supply, turned it on, and tightly placed a few measuring straps around the door.

A constant resonant wave was produced. Although the door remained unchanged to the naked eye, it began to tremble slightly if observed from a microscopic view.

The trembles allowed the instrument to display two precise decimal data easily.

"4.15 meters! Goodness! The people who made this door sure did invest a lot in building it!

"It's so thick that even if it's a hollow-core iron door, it can resist the power of a small TNT bomb!"

Liu Cheng read out the data recorded on the instrument with a look of amazement. The four manufacturing talents glanced at each other, immediately reading what was on each other's minds.

The thickness of the door could be easily solved in a civilized era where they had access to complete tools and machinery.

They could either chemically corrode the keylock position or weaken the lock so that they could easily open the door with external force.

Another option would be replicating and forging the corresponding authentication or unlocking method to open the door effortlessly.

Unfortunately, they were in the current situation on the wasteland, not Earth!

After determining the door's thickness, they excluded some unachievable methods in their circumstances and were left with very few options!

They had an internal discussion and reached a unanimous opinion. Liu Cheng pondered on the decision for a little longer.

Ultimately, he chose to stand up and suggest their plan to Li Hu.

"Captain, we might need to slightly damage this door to conduct a minor experiment."

"Oh?"

The enemy of an enemy was a friend!
