Apocalypse: I built the Supreme Sanctuary a year in advance

Chapter 162 Limited Time Challenge Mission: Iron Fortress

There is a lot to consider when designing a submarine.

After all, people cannot stay in a small, dark place for too long, otherwise they will inevitably develop various mental illnesses.

But designing underwater robots doesn't matter so much.

Anyway, Xu Zhengyang will not go into the water himself, so the robot only needs to have a strong enough shell to withstand the water pressure in the deep sea and be able to launch torpedoes!
Therefore.

In just over ten minutes, Xu Zhengyang and Dabai designed underwater robots of various models and functions.

Do it all.

Xu Zhengyang gave Dabai an order, "Temporarily use all the production capacity of combat robots to produce underwater robots!"

"Okay, master." Dabai carried out Xu Zhengyang's orders meticulously.

*
The resistance of water is very large, so traditional kinetic weapons will have great limitations underwater and their power will be greatly weakened.

Not only that.

Because some of the light's energy will be absorbed when it passes through water, and it will also undergo refraction and scattering, laser weapons cannot exert their full power underwater.

As for Xu Zhengyang's electromagnetic cannon, a little rain wouldn't have much of an effect on it, but if the whole thing was soaked in water...

There's not much difference between that and a fire stick.

The thought of this.

After thinking for a moment, Xu Zhengyang said to Dabai, "Add another torpedo production line in the production area, and then start producing all kinds of torpedoes!"

"Good host."

Dabai agreed and immediately sent a building renovation blueprint to Xu Zhengyang's contact lenses.

At the same time, he said to Xu Zhengyang, "Master, you must first use your magnetic nerve skills to transform this area of the shelter into a room, so that I can set up additional production lines."

Xu Zhengyang was stunned when he heard this.

Only then did he suddenly remember that his shelter had become an aerospace mothership made entirely of special steel.

Naturally, it is not possible to use reinforced concrete to build compartments in the shelter as before.

"it is good."

Xu Zhengyang agreed and immediately used his magnetic induction skills to separate a workshop for Dabai to produce fish according to the architectural drawings given to him by Dabai.

When Xu Zhengyang was converting the shelter into an aerospace mothership, he had almost used up the remaining 50,000 square meters of space from the fifth phase expansion of the shelter.

just now.

When Xu Zhengyang allocated the last redundant space in the shelter to the torpedo production workshop, filling the shelter to the brim.

A series of system subtitles suddenly appeared in front of his eyes:
[Limited-time challenge mission: Iron Fortress (in progress)]

[The shelter is the foundation of your survival in the apocalypse. Now, you need enough steel to continue expanding your shelter! ]

[Mission Objective: Expand the shelter to at least a 2km x 1km x 0.5km steel fortress]

[Task time limit: 29 days, 23 hours, 59 minutes, 54 seconds]

[Quest Reward: Skill Card Transformation (Unique)]

Seeing the main challenge mission suddenly appear before his eyes, Xu Zhengyang was surprised and delighted, "The only skill, transformation?!"

After seeing the mission rewards.

Xu Zhengyang couldn't help but speculate, "Could it be that this skill allows me to turn the shelter into a super robot?

And then drive the shelter like a giant mecha?"

When Xu Zhengyang thought about how he would soon be able to transform into a giant steel beast that was two kilometers long and one kilometer wide, he felt an uncontrollable excitement in his heart!

Xu Zhengyang immediately gave Dabai the order, "Use the Trans-Space Teleportation Platform to gradually occupy all nearby iron mines within a 2,000-kilometer radius.

Let the armed mining vehicles start full-scale mining! "

Speaking of it.

Xu Zhengyang paused and continued, "At the same time, send out engineering robots and have them directly destroy those buildings where no survivors live by blasting.

And then recycle all the steel in the building!"

Generally speaking.

Even if the iron content of the refined iron ore is 60%, the output of iron is only about 0.4 tons to 0.5 tons.

But dismantling abandoned buildings is different. All you have to do is find a way to remove the bricks, concrete and other construction waste from the buildings.

Inside is steel that can be used directly to expand the size of the shelter!
Compared to lumps here and there, it takes an armed mining truck a long time to collect a cart of fine iron ore.

It is easier to collect enough steel by destroying the highly concentrated buildings in the city!

"Good host."

Baymax agreed and sent out 95% of the shelter's engineering robots.

Starting from nearby, we must first blast and dismantle the various buildings in Baicheng that have no survivors living in them, and collect the steel inside!

Dabai followed Xu Zhengyang's instructions.

While reminding Xu Zhengyang, he said, "Master, one cubic meter of iron weighs 7.86 tons.

According to the mission objectives, we want to build a steel fortress of 2 km x 1 km x 0.5 km.

Even if one-third of the interior of this steel fortress is solid.

That would require at least 2000x1000x500x7.86x, or million tons of iron.

This amount of steel is almost equivalent to the annual steel output of some small countries before the end of the world!
Such a big steel gap.

I'm afraid we won't be able to produce enough steel in a month just by relying on the shelter's smelting workshop and recycled construction waste."

After hearing what Dabai said, Xu Zhengyang explained with a smile, "Of course I know that. You do your thing, and I won't be idle either!"

Xu Zhengyang continued to say to Dabai, "Use satellites to search for all the ocean-going ships in the world and mark their locations for me. I will recover them one by one!"

Before the end of the world.

Large ocean-going container ships like those are basically around 1.5 to 3 tons when empty, and they are basically made of steel!
So when Dabai heard Xu Zhengyang's words, he immediately understood Xu Zhengyang's thoughts and said sincerely, "You are worthy of being my master!

Limited by my core algorithm architecture, I will never be able to solve problems with leapfrog thinking like my master."

"Ha ha ha ha."

Xu Zhengyang smiled and said, "But you can help me handle those boring chores in an orderly and meticulous manner.

This is something I can’t do, so we complement each other.”

Xu Zhengyang said.

He immediately followed the coordinates sent to him by Dabai and started to act in the Hurricane light multifunctional mecha in the form of a shuttle!
In the following period of time, Xu Zhengyang and Dabai took a two-pronged approach!

Dabai controls an armed mining vehicle to collect iron ore for smelting, and an engineering robot to blast uninhabited buildings and recycle the steel inside.

Xu Zhengyang drove the Hurricane light multi-functional mecha in the form of a shuttle back and forth between the beach and the shelter.

Clean up the ocean liners that are occupied by plague creatures, then load them into a dedicated dimension and take them back to the shelter.
