However, for Su Wu.
A daily production of 500 snow transport vehicles was more than sufficient.
It was equivalent to forming five new merchant caravans every day.
And a single caravan could transport back tens of thousands of tons of supplies or 8,000 people.
It was a colossal transport tool, rare even in the entire Eastern Continent, let alone the world, in the current apocalyptic era.
"Additionally, we expect to produce 30 Twin-Winged Helicopters and eight Pioneer-class Land Destroyers."
At present, Su Wu only had 25 Twin-Winged Helicopters in total.
If they could fully utilize the resources of Steel City and produce all the expected helicopters,
Su Wu would have an air transport force capable of quickly moving 1,100 tons of supplies at once.
As for the Pioneer-class Land Destroyers, considering Su Wu currently only had one,
producing eight more would mean his most advanced land combat force would increase eightfold.
"Speaking of air transport capabilities."
"The Twin-Winged Helicopters are too extravagant, and the Sky-level unmanned transport drones have limited payload and slow speed."
"Given our current abundance of resources."
"Perhaps we should consider adding a new type of aircraft."
"To strengthen the connection between the Farmer's Courtyard and Steel City, and to quickly support the future outposts that will inevitably spread across the Eastern Continent."
Air transport is one of the fastest and safest methods in the apocalypse.
But even before the apocalypse,
air transport was a relatively luxurious method.
Not to mention, after the apocalypse, almost all large airports were forced to shut down.
Ordinary passenger planes couldn't withstand the random low-temperature cold waves at high altitudes, resulting in extremely high accident rates.
The only ones truly capable of freely navigating the skies,
were fifth-generation or higher military fighter jets.
And the new aircraft specifically designed and manufactured for the post-apocalyptic environment.
As for Su Wu,
he had long had the ability to design and produce fifth-generation military fighter jets.
But pure fifth-generation jets were of little use to him.
Not to mention,
an airport requiring a runway of one or two kilometers,
was already a headache for Su Wu.
The construction costs, maintenance expenses, and so on were all significant.
For the scale of the Farmer's Courtyard,
it was neither necessary nor feasible to go to such lengths.
But if fifth-generation jets weren't suitable, sixth-generation ones might be.
Especially based on the data released by the former federal government on sixth-generation jets.
Most sixth-generation jets had vertical takeoff and landing capabilities.
This addressed Su Wu's biggest concern.
With the abundant resources of Steel City as a foundation,
it was entirely possible for Su Wu to mass-produce sixth-generation jets.
Thinking of it, he decided to act.
After consulting the database,
Su Wu quickly focused on a technical approach related to vertical takeoff and landing.
Superconducting Magnetic Levitation Technology.
The principle of this technology was to use the strong magnetic field generated by superconducting materials at low temperatures, interacting with the aircraft's own magnetic field, to produce levitation and guidance forces, allowing the aircraft to hover and take off vertically.
Although Su Wu was still somewhat unfamiliar with this technology,
with experience in producing the weakened Arc Defense Array of the electromagnetic shield and the super-large electromagnetic railgun,
dedicating time to research it,
he should be able to master it within a day.
After all, the key material required was low-temperature superconductors, not room-temperature ones.
The difficulty was reduced countless times.
"Next is the engine."
If possible, Su Wu naturally wanted an all-electric drive engine.
But the technical difficulty was too high, and it would take a while to achieve.
He had to settle for a mainstream detonation engine used in sixth-generation jets.
With the basic principles and performance of the finished product as references,
Su Wu connected to the simulation test field on the sixth underground level of the core area, invested a bit of Spirituality, and conducted a preliminary simulation study.
He could basically confirm,
that designing a detonation engine from scratch,
would require about 7,500 points of Spirituality.
The estimated total research time was 12 hours.
This investment cost was relatively high for conventional technology.
But considering it represented the core component of the sixth-generation jet, the current sky dominator, it was somewhat justified.
"Once these two core technologies are solved,"
"the rest shouldn't be a problem."
"After all, its primary purpose isn't to fight humans with equivalent technology."
"But for rapid long-range support and ground bombing, with transport as a secondary function."
If the ammunition part of the sixth-generation jet was removed,
it could also carry a considerable amount of cargo.
Its transport capacity wasn't much worse than the Twin-Winged Helicopters.
As for its combat specialization, focusing on ground bombing, precision guidance, and high-speed cruising was sufficient.
Su Wu's main enemies were the Amethyst Crystal Entities.
Second were the super-large civilian shelters that had inherited federal technology.
Having those three combat specializations was enough to handle them.
No need for other complex functions.
At this point in planning,
Su Wu's sixth-generation jet had a complete outline.
The manufacturing cost also became apparent.
Without other miscellaneous functions and with an effort to reduce unnecessary structures during the design process,
the overall manufacturing cost of a sixth-generation jet,
was only equivalent to an Icebound-class Land Battleship.
Moreover, since most of the required rare materials were different,
producing sixth-generation jets didn't conflict with the resources needed for other high-end transport tools, including the Icebound-class Land Battleship.
Therefore, based on past resource reserves and the resources of Steel City,
it was preliminarily estimated that Su Wu could produce over 300 sixth-generation jets at once.
"This number."
"Is a bit too astonishing."
Looking at the results he had calculated himself,
Su Wu was also taken aback.
What did over 300 sixth-generation jets mean?
In the world before the apocalypse,
not to mention sixth-generation jets, even this number of fifth-generation jets,
was enough to annihilate most countries in the world.
It was truly a nation-destroying force.
"Feeling this wealthy for the first time."
"With this air force of fighter jets."
"In the future, the entire Eastern Continent, and even many surrounding areas."
"Could probably be traversed in just a few hours."
Of course, this freedom,
was limited to the air.
Even with vertical takeoff and landing capabilities,
without dedicated ground airports for support,
the sixth-generation jets couldn't land and dock at will.
At most, they could drop some supplies or combat robots at the destination.
After a bit of thought,
Su Wu operated the control panel a few times and forwarded the research task for superconducting magnetic levitation technology to Wei Manman.
That soft, easily bullied girl,
had an incredible knack for luck when it came to researching materials.
Assigning this task to her was a perfect fit for her talent.
As for the remaining tasks of researching the engine and other components,
Su Wu planned to handle them himself.
But before diving into the research,
he needed to arrange a few more things and set up other research plans.
"With the resources of Steel City secured,"
"both the Pioneer-class Land Destroyers and the Icebound-class Land Battleships will see a significant increase in scale."
"Considering that even in the merchant caravans, they mainly serve as combat forces, with transport as a secondary function."
"It's time to design a set of new dedicated weapons for them."
Simply serving as transport tools,
was a waste of the resources spent on building these two land battleship-level base vehicles.
Only by maximizing their firepower could they be truly utilized.
This point,
was very easy to achieve after the highest-level super-large electromagnetic railgun was developed.
Just by reducing the specifications of the super-large electromagnetic railgun,
splitting it into smaller, more portable large electromagnetic railguns and ordinary electromagnetic railguns,
they could be applied to the land battleships.
"The specifications of the large electromagnetic railgun are still a bit too high."
"It's only suitable for installation on the still-in-development Retribution-class Land Cruiser."
"The next level down, the ordinary electromagnetic railgun, is perfect as the main gun for the Pioneer-class Land Destroyer."
"As for the Icebound-class Land Battleship."
Su Wu pondered for a moment.
Combining the electromagnetic railgun with the structure of a multi-barrel machine gun,
he redesigned a weapon named the Thunder-class Opto-Electromagnetic Cannon.
This weapon consisted of multiple barrels.
Although each barrel had a diameter of only 32 millimeters,
with the technology of the electromagnetic railgun, its destructive power was still incredibly shocking.
Moreover, its biggest advantage was its ultra-high firing rate.
It could fire 12,000 rounds per minute.
Equivalent to a true "ten thousand cannons firing at once" in a minute.
The mere thought of such a scene was enough to make any enemy tremble.
"Also, the weapons are sufficient."
"The remaining consideration is defense."
"The existing Arc Defense Array is ultimately just a weakened version of the electromagnetic shield."
"It's fine on tank-level combat units like the Heavy Main Battle Spider Robots."
"But on land battleships with more abundant energy supply,"
"it's a bit mismatched."
"Greatly wasting that high configuration."
"So even if we can't develop a true electromagnetic shield for now,"
"we need to find a way to truly utilize the vast energy carried by the land battleships."
"This research plan,"
"can be listed to proceed after the sixth-generation jet research is completed."
February 7th.
After completing the research task for the sixth-generation jet,
Su Wu gave himself a short break.
The tasks of research were endless, and there was no need to rush.
Of course, more importantly,
Su Wu felt that he was already terrifyingly strong.
Just by following the original plan and continuing to develop,
whether it was against the Eastern Continent government, the federal government, or facing the Amethyst Crystal Entities,
there was no longer much pressure.
Taking Chen Yue and Wei Manman with him,
Su Wu strolled through the now extremely vast garden world on the third underground level.
With the development of the Farmer's Courtyard and more abundant resource supply,
the scenery here had become even more beautiful and pleasant.
Not only were the sky, sun, clouds, and distant mountains and ocean simulated to perfection,
but the real plants and forests inside were also better cared for than those outside, making it more suitable for human activities.
For example, one could freely lie in the sea of flowers,
without worrying about insects or other creatures lurking beneath.
Micro-robots created by 3D printers,
replaced the roles of insects and earthworms in nature,
ensuring that the flowers and soil here were always in the most suitable condition.
Even flowers like roses,
no longer had sharp thorns or other things that could harm humans on their stems.
Everything had become harmless and delicate.
"So beautiful."
Wei Manman gazed at the sea of flowers rippling in the breeze, her eyes sparkling with excitement.
No matter how many times she saw it,
for her,
the scene here was like a dream.
As beautiful as the sweetest dream in a fairy tale.
"I had a part in this."
Chen Yue turned around, her hands behind her back.
Looking at her best friend, she proudly proclaimed in a lively tone.
"The No. 2 plant growth potion I developed."
"Keeps the flowers here in full bloom until the end of their lives."
"And it won't be long."
"Those small groves over there will grow into a lush forest."
"Then, we can go play hide-and-seek there."
"Okay, okay."
Wei Manman nodded vigorously, already enticed by the idea.
At this moment, these two girls in the prime of their lives,
were as naive as if they had returned to their childhood.
Su Wu quietly watched this scene,
viewing them, along with the surrounding garden and the distant clear spring, as part of the scenery.
Evening.
In the third underground garden, where the light was strictly adjusted to twilight,
Su Wu and the others, tired from their stroll,
casually sat among a cluster of flowers.
Su Wu reached out and pulled Chen Yue into his arms, gently kissing her.
The girl in his arms, sensing something,
her soft body began to tremble slightly from nervousness. The snow-white skin by her ears also unconsciously showed a faint blush.
After being together for so long,
their relationship seemed ready to take the next step.
Wei Manman, watching their increasingly intense actions beside them,her face flushed red.
She lowered her head.
Her body quietly moved back, like a startled little rabbit.
Although she and Su Wu had done something they shouldn't have even earlier than Chen Yue,
her timid nature, faced with such a stimulating scene,
still couldn't help but feel shy.
She didn't dare to stay near them anymore.
But just as she carefully moved further away,
Su Wu, who was being intimate with Chen Yue, seemed to notice something.
He looked up.
Seeing the girl who had moved several steps away, with her easily bullied expression.
A thought crossed his mind.
"Come here."
"Help me push later."
Wei Manman's eyes instantly widened.
Somewhat disbelieving.
"Huh?"
