"Then the existing standard dormitories, along with various areas for ordinary people to engage in activities, must continue to be constructed."
"Until we reach a capacity sufficient to accommodate ten million people."
Su Wu had suffered enough from the lack of space to house the population.
Considering the future, where it was highly likely that the influx of people from outside would continue.
Continuing to build standard dormitories became a matter of course.
Moreover, Su Wu did not think highly of the shelters in Jianghe City, which were built by ordinary construction teams with varying quality.
These shelters.
Even the official shelters with the highest construction standards, ranked in the top ten.
Still used ordinary concrete.
If they encountered a magnitude seven or eight earthquake.
They could suffer significant damage.
And based on the limited external information Su Wu had accessed since taking over the official shelter in Jianghe City.
Although there had not been any super earthquakes like before.
Various small-scale earthquakes below magnitude nine had persisted.
For safety reasons, investing heavily in industries and other capital-intensive sectors within these fragile shelters was clearly not cost-effective.
It would be better to casually build some dormitory areas and plantations.
To temporarily house the population and produce food.
This way, even in the event of an accident, the losses would not be too severe.
In the future.
Once the farmhouse courtyard developed to a certain scale and had enough space.
Su Wu would gradually relocate everyone in Jianghe City to the farmhouse courtyard.
Forming a super shelter that could accommodate millions of people at once.
"At that time, the innermost core area will be my own living space."
"The second ring outside will serve as a major food production area."
"The third ring will be for research and development and the living area for high-level talents."
"The fourth and fifth rings will be ordinary residential areas."
"The sixth ring will be for industrial manufacturing."
"The seventh ring will be for outer military defense."
"A complete super shelter will be established."
Su Wu envisioned the future.
Relying on rapid cement, a material from the interstellar era.
Concentrating all the population and resources in the same shelter.
Maximizing disaster resistance.
Even if it were to sink deep underground due to an earthquake.
The massive volume of the super shelter would still allow for safe survival and continued development.
At most, acquiring resources from the outside would become a bit more challenging.
Daily water usage would completely rely on the internal recycling and filtration system of the shelter.
Psychologically, it might be a bit hard to accept.
Aside from that.
Su Wu opened the apocalypse system panel.
His gaze fell on the shelter level above.
[Current Territory: Developing Medium Shelter (7%), Daily Fixed Survival Points +5.]
After Su Wu initiated the second phase of external expansion construction for the farmhouse courtyard.
The level of his shelter quietly changed from a powerful personal shelter (max) to a developing medium shelter (0%).
The increase in level.
Also raised the daily fixed survival points from 4 to 5.
Don't underestimate that mere increase of one point.
With Su Wu's now even more powerful technology and industrial productivity.
Its impact far exceeded the past.
To put it in perspective.
If the initial one survival point was roughly equivalent to resources worth over a hundred thousand.
Now, it could yield resources equivalent to tens of millions, or even hundreds of millions.
It was a significant income that Su Wu still could not overlook.
Thus.
Maximizing the construction of the farmhouse courtyard shelter.
Allowing the shelter to continue upgrading from its current medium level to large, and even super-large, to gain more survival point rewards.
Became an essential option for Su Wu's development.
For Su Wu, building the auxiliary shelters well.
Was not as important as advancing his own farmhouse courtyard shelter a little further.
Of course.
That was all a long way off.
Currently, the farmhouse courtyard shelter.
Was undergoing its second phase, expanding from a diameter of 100 meters to 500 meters, and the very first layer had not even been fully excavated.
One could only say that everything was just beginning.
In the afternoon.
At the core area of the farmhouse courtyard, six levels underground.
Simulation testing ground.
"The 97th vibration test begins."
In the testing ground.
A sealed room, one meter thick, constructed with rapid cement.
A dull rumbling sound echoed.
The shockwave from the violent explosion caused the walls facing inward to tremble.
Yet ultimately left no permanent damage.
"Very good."
"The main structure has not suffered any significant damage."
In the control center on the first underground level, Su Wu observed remotely.
Looking at the testing report of the sealed room, he felt a long-lost sense of joy.
Having obtained rapid cement for such a long time.
Su Wu still had not fully explored all its characteristics.
This time.
After attempting to mix the special alloy melted from the Exoskeleton Armor seized from the Snow Wind Mercenary Group.
With rapid cement to form a one-meter-thick barrier.
Su Wu unexpectedly discovered.
Its strength had further achieved a near qualitative leap.
It was not a simple quantitative increase from one meter of concrete to twenty meters of concrete.
But rather a change in material properties, akin to the transformation from soil to steel.
With this new characteristic enhancement.
Even simulating the intensity at the epicenter of the super earthquake Jianghe City had previously encountered.
Could not truly tear it apart.
This also meant that if Su Wu thickened the outer walls of the shelter entirely with rapid cement to one meter.
He would no longer have to fear disasters like earthquakes.
"One cubic meter of rapid cement walls, excluding the alloy frame and water, requires exactly one ton of rapid cement."
"Calculating this way."
"To replace the core area of the farmhouse courtyard shelter, which has a diameter of 100 meters."
"With one-meter-thick rapid cement outer walls."
"Would require approximately 26,000 tons of rapid cement."
"That is about the production capacity of two to three days, consuming less than 30 tons of rubber raw materials."
Su Wu quickly calculated.
Finding that promoting this construction standard in the core area was not very difficult.
Even the currently under-construction second ring area.
Could also use one-meter-thick rapid cement as the outer wall.
Each layer would only need less than 20,000 tons of rapid cement.
Supplying it would similarly pose no pressure.
And the other raw material, the alloy similar to Exoskeleton Armor.
Was not a challenge for Su Wu.
With existing physical references available.
There was no need to consume much spiritual energy to directly analyze its raw material formula.
