After listening to Lin Ziming's arrangements,

Wang Qiang and Li Bai'an nodded in unison, then turned and left to make their preparations.

Compared to the elusive spiritual energy, the movement of Y particles is not as difficult to grasp.

After all, these particles are not very small, and the currents they form can be felt by a cultivator like Wei Fan, otherwise, there wouldn't be such a term as 'evil energy entering the body'.

Of course.

This is just one possibility, as no one knows how many Y particles appear at "dawn".

If there are too few, not even Wei Fan could do anything about it.

For instance, when he first entered the mountain gate, Wei Fan merely felt a bit cold, without sensing the presence of Y particles—it was because they were too scarce, almost imperceptible.

On the other side.

After separating from Li Bai'an and Wang Qiang, Lin Ziming found Daoist Huang:

"Daoist Huang, there's good news and bad news. Which do you want to hear?"

Daoist Huang stroked his beard, glanced thoughtfully at Wang Qiang, who was busy with handover matters nearby, and said:

"Colonel Lin, is the good news that you've possibly confirmed the existence of the ancestral Earth Palace or array? As for the bad news... are you preparing to warn me that you might end up digging up part or even all of the cliff?"

Lin Ziming: "?! "

Have you old Daoist read the script or something?

Daoist Huang clasped his hands with a chuckle:

"Simple psychology and behavioral analysis, Colonel Lin, you have to trust science."

Lin Ziming continued, "..."

He then rubbed his temples speechlessly and admitted bluntly:

"Yes, if nothing goes wrong, the Earth Palace left by Zhang Daoling is likely to exist, and mostly lies below the cliff.

But it definitely isn't suppressing any nether demons; rather, it seals another kind of substance."

As he spoke, he suddenly thought of something and asked:

"Daoist, in the past, have the predecessors of Qingcheng Mountain ever dug up this cliff?"

Daoist Huang shook his head at his words:

"The industrial level in ancient times was limited, moving mountains and carving stones was not easy.

Moreover, breaking the earth involves considerations of feng shui, so the sages of Qingcheng Mountain in ancient times practically never had such an idea.

As for post-founding industrial levels, they have gradually matured, but considering various reasons, successive sect leaders eventually abandoned this thought."

Although Lin Ziming does not believe in feng shui, he obviously needed to offer some commercial praise at this moment, so he politely said:

"Following ancestral precedents, venerating the ancient and respecting the Way, no wonder it's a virtuous sect with a long-standing legacy."

Daoist Huang gave him an odd look:

"It's not that mysterious; the biggest reason is actually money, the cost of bringing an excavator into the mountains is quite expensive."

Lin Ziming: "....?"

Daoist Huang shrugged:

"The ownership of the back mountain of Qingcheng Mountain has always been in the hands of our Daoist Palace, and indeed some forests are quite obstructive, making it more peaceful after excavation and infrastructural development.

However, the Qingcheng lineage is not the type to exploit money; a few years ago, the sect leader went down the mountain to inquire about prices and was scared back in less than an hour."

Lin Ziming: "...."

Finally, he slapped his forehead and sighed softly:

"....So Daoist, if Wang and her team get results later, are you in agreement with excavating the cliff?"

Daoist Huang nodded and said candidly:

"If it were before today, I might not have agreed to such a thing, as this place for meditative practice has been handed down through my lineage for years.

But now that we're touching on spiritual energy, just the official value of enlightening the way for us cannot be replaced by a mere cliff.

Besides, to not keep any secrets from Colonel Lin.

Actually, when I was a child meditating, I thought about digging open the cliff one day, probably like the kids who want to blow up a kindergarten."

Upon hearing this, Lin Ziming exhaled gently with relief.

It has to be said.

Daoist Huang is indeed a very reasonable person, dealing with such people doesn't feel as tiring.

In a sense, this is also a kind of manifestation of 'dao heart'.

After that, the two temporarily parted ways.

Lin Ziming went to discuss the relevant matters of sensing condensed particles with Wei Fan, not wanting to place all bets on the instruments, a two-pronged preparation was more secure.

Daoist Huang went to find their sect leader to inform them about the possibility of excavating the cliff.

The current sect leader of Qingcheng Mountain is surnamed Guo, with the Daoist name Master Qingxu.

Also one of the members selected for this cultivation project, mainly responsible for the handover matters of the mountain gate and Daoist Palace this time.

Of course.

Excavating the cliff is just a theoretical possibility, after all, at this moment Y particles and the like haven't been detected.

It can only be said by combining the classical records, Zhang Daoling's Daoist Palace most likely suppresses evil energy below.

An hour later, a ray of sunlight emerged from the edge of the earth.

It has to be said.

If one had nothing better to do on a regular day,

coming to a place like Qingcheng Mountain for a vacation, brewing a pot of not particularly expensive tea early in the morning, leisurely watching the sunrise at the cliffside would also be a good choice.

However, Lin Ziming and the others did not have such leisure at this time; they had more pressing matters to attend to.

Half an hour earlier, several precision devices had been placed at various corners of the cliff.

At the same time,

numbers continuously flashed across several screens.

"The current outdoor temperature is minus 2.5 degrees, humidity is 56.4% with no condensation, power supply device DC5V, peak current 1A, no abnormalities!"

"Number of sensors: 16, atmospheric pressure: 676.7mmHg, boiling point of water: 97.3°, no abnormalities!"

"Current wind speed is 1.6 meters per second, gentle breeze, no abnormalities!"

"Oxygen concentration: 21.6%, slightly above standard concentration, total nitrogen deposition has increased from before, current deposition value is 5.2 kilograms per hectare, raised nearly 100% from 75 minutes ago!"

Hearing these words, Wang Qiang couldn't help turning to Li Bai'an and said:

"Academician Li, it seems your previous guesses were correct, the 'loading' process is still happening here at the cliff."

Li Bai'an slowly nodded:

"I hope the subsequent detection will also proceed smoothly."

The reaction where microbes absorb nitrogen to produce Y particles does not produce pressure, so the nitrogen in the air can only fill naturally by a difference in volume.

In the case where the surrounding areas' gas volumes are fixed, this difference filling speed is remarkably slow.

Thus, over an hour has passed, and the nitrogen deposition value has only increased by about 10%.

In general areas, nitrogen deposition values typically are 8.7 kilograms per hectare, occasionally exceeding ten.

The deposition values in farmlands are higher, usually around twenty, and in some areas, even reaching thirty.

So, the total nitrogen level at the cliff area is indeed somewhat scarce.

Amidst the conversation between Wang Qiang and Li Bai'an, assistant Zhao Zhiming suddenly raised his voice by a few decibels:

"Academician Li, the nitrogen content is decreasing rapidly!"
