Actually, a long, long time ago, back when Cao Yi and others had just begun their spiritual awakening, the rabbits had already attempted to verify the feasibility of indigenous cultivation.

The final result was harsh and obvious:

Not feasible.

Because there is no spiritual energy present locally.

However, if a cultivator has a certain amount of spiritual power stored in their inner sea, they can indeed perform various kinds of magic locally—without a reduction in power, although the spiritual power consumed cannot be replenished.

Now, with the development of the L17 environment module for cultivation, the rabbits have thought of another possibility:

If the spiritual energy from the Damo Realm is 'purified' through relevant modules of the L17, and then transported back to the local area, would it be possible for ordinary people to cultivate locally?

Although the daily throughput of the light gate is quite large and the energy is becoming increasingly stable, they can't just stuff an unlimited number of people in it.

Researchers, on the other hand, are relatively simple. After all, domestic researchers already have high mobility, and there is no single gathering area that would be monitored.

But the military is very troublesome.

Firstly, because of the vast territory, both the long coastline and the border line must have troops stationed to prevent any covetous thoughts from others.

Secondly, the high number of personnel movements would easily expose any secrets.

After all, the warriors sent to the Damo Realm are definitely the elite of the elite.

There are indeed quite a few of these elite altogether, but their distribution is relatively fixed, making mobilization very troublesome.

Currently, there are over 25,000 warriors in the Damo Realm.

If you grit your teeth, sending another thirty or fifty thousand is indeed not a big problem.

Even if it involves a war that concerns the concept of "national fortune," mobilizing ten thousand more people is not impossible—after all, there's a detachment of over 300,000 nearby in the Eastern War.

But if more than that...

Those who understand will understand.

Compared to the advantages of the Damo Realm's indigenous people, the main advantage is having 3 million spirited young men and the powerful national power supply.

As long as there's no third world war or alien invasion, the latter is basically unlikely to be undermined.

But if the former's numbers decrease, the overall advantage becomes quite limited.

After all, only 20% have four or more spiritual roots.

It's not that those with five spiritual roots can't cultivate, but the current cultivation resources can only be prioritized for the front-line soldiers.

20% of 3 million is 600,000, while 20% of 150,000 is 30,000; the gap speaks for itself.

Therefore, achieving conventional cultivation effects locally is a strategic-level important mission.

As for the personnel involved and confidentiality issues, those are secondary considerations; problems that require human and material resources to solve are trivial in the face of the rules of the world.

If worse comes to worst, just like in the Damo Realm, communication can only happen once or twice a month.

Thus, verifying whether local cultivation is possible is an urgent matter.

In the office.

Facing Qin Zhendong's questions, Lin Li considered for a moment and said:

"Boss Qin, per the organization's previous request, I brought back a set of alloy house based on the L17 cultivation environment module this time.

We call this alloy house the L17 version cultivation room. We have finished debugging the relevant components, and it should be able to handle the experimental tasks."

Upon hearing this, Qin Zhendong's expression jerked, and he gestured to Lin Li:

"Let's go, take me to see it."

Ten minutes later.

Qin Zhendong and Lin Li arrived at an open space near the light gate and met with Lin Ziming, who was waiting there.

"Boss Qin, this is the L17 cultivation room jointly made by our Plant Biology Laboratory and the Physics Research Group."

Lin Li touched the outer wall of the cultivation room and introduced it to Qin Zhendong:

"The cultivation room is a standard cube with a length, width, and height of three meters each.

The cultivation room is connected to a gas storage device on the outside, which stores a large amount of Damo Realm air with a 38.8% spiritual energy concentration. The capacity of the gas storage device can be set independently without worrying about gas pressure issues.

Generally, five cubic meters of air is roughly enough for a cultivator below the sixth layer of Qi cultivation to cultivate for a day."

Looking at the cultivation room, Qin Zhendong nodded slightly, but didn't delve into questions about air consumption yet.

After all, whether this thing can be used normally on local soil is still unknown—the previous spatial bag was a perfect example, usable but not completely usable.

If this set of L17 cultivation module turns out to be like the spatial bag, consuming 20 times more resources when on local soil, then it doesn't matter how low the basic consumption is, it won't be of much use.

So the current key factor is still to experiment with the practicality of the cultivation room.

Thus, he turned his head and said to Lin Ziming:

"Colonel Lin, we'll have to trouble you to conduct the experiment personally again."

On the way over, Lin Li had already introduced this to him; the test subject this time is still Lin Ziming—no matter from which perspective, this Colonel is a perfect candidate.

Then, seemingly to reassure Lin Ziming, Qin Zhendong pointed at the emergency team not far away and said:

"Colonel Lin, don't worry, our medical support is right beside us, ready to provide assistance no matter the situation."

Upon hearing this, Lin Ziming couldn't help but show a hint of emotion on his face.

However, just as he was about to say the next line, "I won't let the organization down," he heard Qin Zhendong say:

"The medical team even considered the most extreme shortage of blood, so they've prepared blood bags, more than a dozen... all containing your blood, so there's no need to worry about compatibility issues."

Lin Ziming: "...?"

Subsequently, this blood-extracting... fervent warrior entered the cultivation room, full of questions.

This experiment mainly aimed to test whether cultivators could cultivate locally, so the related testing equipment and procedures were relatively simple—as long as Lin Ziming didn't have a sudden blood burst, he would just need to be a mere tool throughout the process.

Qin Zhendong took advantage of this free time to discuss other issues with Lin Li:

"Academician Lin, Academician Pan and Professor Lu have already reached the Damo Realm, right?

How is it? Is there any new hypothesis regarding the space bag issue we encountered last time?"

Lin Li hesitated for a moment, then replied:

"Professor Pan tends to be more meticulous, so they are still in frontline experimentation and haven't made any related judgments. However, Professor Lu has put forward a new hypothesis."

The Professor Lu Lin Li mentioned is Lu Chaoyang.

Perhaps due to not having been introduced in detail earlier, some classmates mistakenly thought of him as another person.

However, unlike the protagonist with the same surname in a certain novel, Lu Chaoyang—Professor Lu—is a real-life super genius and doesn't rely on any academic system support.

This year, Professor Lu is 40 years old. He became a full professor at the University of Science and Technology of China at the age of 28, and is known as a quantum genius, Mr. Xiao Yang.

He's the kind of person that makes you feel like you haven't achieved much after knowing about him.

Up to now, he has published one RMP, five Nature/Science articles, nine Nature sub-journal articles, four PNAS articles, one Physics Reports, and twenty-nine Physical Review Letters, with over 6,700 citations.

Compared to the protagonist in a virtual novel, Professor Lu Chaoyang may not have become an academician by the age of twenty-two or twenty-three, but he is a real person.

Scientific research requires a lot of time and effort; relying on a black-tech system to become an academician in his 20s may seem incredible.

But in reality, this disrespects scientific research—note that this is about the reality setting, not an opinion on the character. (See note)

Hearing that Professor Lu had insights, Qin Zhendong's interest was piqued:

"Oh? What is Professor Lu's judgment?"

Having done his homework before arriving, Lin Li quickly replied:

"Professor Lu believes the reason why the spatial bag is difficult to use locally might be due to it 'cutting out' space from the Damo Realm locally, thus making it challenging to integrate into this different local space."

Seeing that Qin Zhendong seemed to not fully grasp this explanation, Lin Li continued:

"Let me give you an analogy.

For example, in front of us are two equally flat snowy grounds, one called A and the other B.

We use a shovel to scoop out a pile of snow from the snowy ground A, leaving a gap in A's space.

If you put this snow back into its original gap, with just a bit of smoothing, the snowy ground can return to its original state.

Then if we put the dug-up pile of snow onto ground B, what happens? — Initially, this pile of snow cannot integrate into ground B unless you forcibly smooth it.

The two snowy grounds are like two worlds, and the space within the spatial bag is like that pile of snow.

The effort used to smooth it on ground B is the additional mana Colonel Lin and his team expended last time.

Because the spaces of the two worlds don't overlap, merging them requires a trade-off.

The good news is that both the space of the Damo Realm and the local space belong to 'snowy ground' rather than ice, meaning that although integration is difficult, it's not impossible.

As for why items within the spatial bag are universally applicable, it can be understood through placing certain items on snowy ground—so long as the ground is flat, they can be used on both snowy grounds simultaneously.

Whether it's elixirs from the Damo Realm or supplies we send there."

Qin Zhendong pondered deeply:

"So, if we want to use a spatial bag locally, does it mean we must complete the manufacturing process locally?"

Lin Li hesitated for a moment before saying:

"In theory, yes, but Professor Lu also suggested another view:

If the technological focus of spatial bags is in the part of the rules that the manufacturing materials reflect, we might be able to first prepare this part of the materials in the Damo Realm, and then complete the final step locally.

It's like a zippered bag: we first sew the zipper and fabric but never close it.

We bring it back locally in the state of one piece of fabric, and then zip it up, turning its interior into local space.

Of course, there's no theoretical basis for this speculation, it's purely an idea divergence."

"I think I understand your point."

Qin Zhendong rubbed his chin, about to say something.

Suddenly, Lin Ziming burst through the door of the cultivation room and rushed towards them, saying:

"Boss Qin, the cultivation module... can be used locally!"
