"What? Wu Fan is already dead?"

Upon hearing Mingmou's deduction result, Lin Li's pupils immediately shrank slightly, and he quickly asked:

"Teacher Mingmou, this deduction result... um, how certain are you? Could there be some error?"

Mingmou shook his head upon hearing this, seemingly still feeling regret over Wu Fan's death:

"The certainty is almost tenfold. You may not understand that the 'Great Deduction Technique' is generally very accurate in previous deductions.

Especially as Wu Fan is merely a mortal, the deduced result is almost impossible to be wrong, and I am a professional deduction cultivator."

Seeing this, Lin Li could only let out a long sigh with a complex emotion:

"Ah..."

Although he didn't have as good a relationship with Wu Fan as Wang Qiang and Lin Ziming did, he had interacted with this young man a few times and knew Wu Fan was actually quite a decent fellow.

Now, suddenly learning of the deduction result that Wu Fan will certainly die, he felt somewhat saddened.

As the first discoverer of the Light Gate, his obscure and unclear death in the Damo Realm indeed made people feel a sense of sigh and regret.

Then Lin Li thought of Lin Ziming.

His clan member had always felt guilt toward Wu Fan, after all, in a certain sense, Wu Fan suffered in his place.

If Lin Ziming learned of Wu Fan's "death," it would likely become an unresolved lifelong regret.

Meanwhile, as Mingmou and Lin Li were talking, Zhang Guanghua happened to bring Wang Jun and several warriors responsible for guarding the stone slab back to the command room.

Lin Li noticed Wang Jun's expression was very serious at this moment, appearing to have important news to report.

Thus, he could only temporarily suppress his sadness, muster his spirits, and stepped forward to shake hands with Wang Jun:

"Researcher Wang, long time no see."

Then he casually found a topic point, pointing at the stone slab:

"How is it, is there any research result on the stone slab's era?"

Wang Jun nodded, took out a document from his body, and handed it to Lin Li, speaking solemnly:

"Captain Lin, I was just about to look for an opportunity to report this matter to you.

A few hours ago, the detection report just came out, indicating that the engraved era of this stone slab should be over 2 million years ago, clearly not belonging to the current and Ancient Times eras.

Additionally, we found an abnormal situation..."

Lin Li picked up a Ma Ning-style thermos cup and casually asked:

"Oh? What abnormal situation?"

Wang Jun took a deep breath, tightly looking at Lin Li, and spoke word by word:

"We detected residual electronic energy levels on the stone slab, which means... the stone slab image is suspected to be laser engraved."

Clang—

Lin Ziming failed to hold it steady, and the thermos cup heavily fell onto the table, spilling goji berries and tea.

One goji berry even bounced perfectly onto the center of Lin Li's forehead, appearing like Nezha's brow mark.

However, Lin Li didn't care about this at all and stared straight at Wang Jun:

"Researcher Wang, what did you say?"

Not only Lin Li, but even Zeng Gu Cheng sprung up beside them—even Mingmou had a face full of astonishment, after all, he was also a science fiction writer and naturally understood the significance of Wang Jun's discovery.

Under the gaze of several pairs of eyes, Wang Jun exhaled a long breath, glanced around, and explained:

"Captain Lin, initially during the identification of the stone slab era, we found its engraved image was too realistic.

And the stone slab's hardness is very high, making manual engraving unlikely.

At that time, we didn't think of the possibility of laser engraving but rather pondered whether other cultivation methods were used for this step.

Hence, we first detected residual Spiritual Energy, and found the detection result was zero—since it came to this step, I thought we might as well follow up with the subsequent standard process.

Little did we know, once checked, we were shocked; my assistant Xiaozheng actually discovered traces of suspected electric tracks!

So, we began trying various methods, and eventually, with the assistance of chirped pulse amplification technology, it was determined that the surface of the stone slab had traces of photoelectric effect and high-energy agglomerate remaining."

As everyone knows.

The lifetime of leptons is complex, with the lifetimes of electrons, muons, and tau particles shortening in sequence.

Electrons are very long-lived, while tau particles have a short lifespan.

Neutrinos are difficult to detect, and currently provided experimental data is the lower limit of lifetime to mass ratio.

Therefore, when a region experiences a high-energy photoelectric effect, if the storage environment is good, traces can be detected not just after millions but even tens of millions of years.

The specific operation process is actually very straightforward, still a foolproof operation.

First, use chirped pulse amplification technology to adjust the laser energy level, and then utilize the electric field gradient at the beam waist of the highly focused laser beam to generate a restoring force to "capture" large molecules.

Then model the nonlinear behavior of the polarization vector of the medium; as long as the overlapping bandwidths of the composite field show up, it indicates that a high-energy photoelectric effect has occurred.

You can even reverse-calculate the era when the event occurred through the field strength traces where the photoelectric effect took place.

As for why this technology isn't frequently used in archaeology...

Honestly, which dinosaur fossil would have been laser engraved on it?

In summary.

Finding traces of laser engraving's field strength on the stone slab is undeniably an earth-shattering revelation!

Amazed, Lin Li had most of his sadness over Wu Fan's death driven away.

No choice, this news was incredibly shocking.

As mentioned before.

The so-called 'Ancient Times' in the Damo Realm roughly spans from two to thirty thousand years ago from today, the period known for cultivation prosperity—the number could extend up to a hundred thousand years under extreme conditions.

And before the 'Ancient Times,' there were certainly other preceding civilizations in the Damo Realm, because no civilization could start out at a complete pinnacle.

Just like the pinnacle of martial might during Emperor Wu of Han's era in ancient Huaxia.

Such peaks couldn't appear out of thin air; other civilizations (emperors) surely existed before the Han Dynasty, and only long-term quantitative changes could lead to qualitative changes.

After all, the Damo Realm's civilization isn't some primordial creation without innate gods and demons, based on the information the rabbits have already grasped, the universe where the Damo Realm resides is at least several billion years old or even older.

Hence, the rabbits were psychologically prepared for one or several civilizations to exist before the 'Ancient Times.'

But no matter how open-minded the rabbits might be, they absolutely never thought that the preceding civilization would comprehend lasers!

This is not at all in line with cultivation!

Most readers should know these few chapters are collaborations, Uncle Tong blessed me with some, and I'm just paying homage.

I didn't say "Tui Beitu" was real, I said it's interesting to look into, quite fascinating.

So why did someone outright label me with pseudo-science for deduction...
