Friends with a deep understanding of military knowledge should know.

The current Type 07 military boots used by the rabbits have shafts made from high-density flame-retardant nylon material, with a Kevlar layer in between, and a fabric lining.

The soles are integrally-cast rubber, with a leather insole, and three nails in the heel of the insole.

These military boots often provide a rebound force when the heel presses down on the ground, allowing for a preliminary judgment of the thickness and type of stone layer on the ground.

Encountering some experienced old soldiers, they can even analyze whether the stone is marble or granite.

Especially for reconnaissance soldiers like Chen Jiasong, the sensitivity of their boots is much higher than ordinary Type 07s — for a simple reason, to detect anti-tank mines.

In fact, it's not just him. Those who become squad leader-level soldiers of the reconnaissance troops are basically human walk detectors.

Thus, they can often find things that are hard for ordinary people to discover.

Just now, when Chen Jiasong walked past the current position, he clearly felt a significant difference in the feedback rebound between his front and back heels.

It's like suddenly stepping on an iron block while walking on a wooden board, a situation that shouldn't occur on the same piece of ground, creating a strong sense of dissonance.

After detecting the anomaly, Chen Jiasong fixed his gaze on the ground, furrowing his brows, while holding a flashlight in one hand, meticulously searching for something.

About half a minute later, he suddenly reached out a hand towards Chu Fan:

"Xiaochu, give me your canteen."

"Oh, okay."

Chu Fan quickly took off the military canteen from his waist and handed it to Chen Jiasong, then held his gun in a guard position.

Chen Jiasong took the canteen, unscrewed the cap, and gently poured it onto the ground.

Drip, drip, drip —

Soon, the entire liter of water had fallen onto the stone floor.

Previously mentioned, this attic was like a guest room, with a relatively high level of decoration.

Therefore, even though the floor was made of stone, its surface was very smooth, without raised gravel.

Under normal circumstances, the poured water should spread at the drop point, then gather into a not very obvious but visible small pool at the center, which would take a while to air dry.

But surprisingly.

The canteen of water poured by Chen Jiasong barely pooled up on the ground before it suddenly began to noticeably seep.

Two or three minutes later, all the water stains disappeared, revealing several crevices imprinted by the watermarks on the floor!

Chen Jiasong handed the canteen back to Chu Fan, and reported through the communication device to Zhang Yaqing:

"Company Commander, there is a discovery at the A5 target attic, a small hidden compartment on the floor, approximately half a meter square.

Based on its arrangement as an uninhabited attic, there could be something inside.

Considering the existence of extraordinary powers in the Damo Realm, we did not open it."

Soon after Chen Jiasong finished reporting, Zhang Yaqing's reply came through the communicator:

"Message received, Squad Leader Chen, you did a great job!

Please stay put and do not open the compartment on your own, I will be there shortly!"

Ten minutes later, Zhang Yaqing arrived outside the attic with Wei Qiangsheng and exchanged nods with Chen Jiasong.

Then Chen Jiasong briefed the situation:

"We first... then... after entering the room, I found this part of the floor seemed a bit off, and pouring water revealed this hidden compartment."

Zhang Yaqing patted him on the shoulder, acknowledging his good work.

This time, Longxing River arranged over twenty teams to explore the Mo Family Manor. Although other teams had discoveries, they were mostly common gold and silver ornaments, with three Spirit Stones being the best find.

The discovery of a hidden compartment like Chen Jiasong's was a first, let alone the fact that its location seemed somewhat dissonant.

Then Zhang Yaqing said to Wei Qiangsheng:

"President Qiangsheng, it looks like we need your expertise to inspect it."

Wei Qiangsheng smiled. Now his command of Mandarin was good enough that he didn't need Wei Niandong's help, speaking fluently with a second-level proficiency:

"Small matter, small matter, Director Shi already told me before coming that I should do whatever needed."

Then he walked around the hidden compartment area for a careful inspection, shook his head, and said:

"Company Commander Zhang, there are no Spiritual Energy fluctuations around here; the entire building looks very ordinary.

Either the items in the compartment are of general value, or the owner deliberately left no traces of Spiritual Energy-related means, to avoid exposing themselves.

Without signs of Spiritual Energy, even a Cultivator's divine sense can't detect these hidden compartments, so I think the latter possibility is greater."

Upon hearing this, Zhang Yaqing pondered for a while, then turned to the two engineers who came with him and waved them over:

"Xiaolin, Xiaomeng, put on the bomb suits, start up those two generation-one-and-a-half, and use the drilling machine to take down the compartment."

The 'One-and-a-Half Generation' mentioned by Zhang Yaqing refers to a certain enhanced version cracked by Hua Jun's team based on the Tier One Spiritual Shield.

The specific operation involved optimizing some of the useless runes under the assistance of an industrial production line experiment, enabling the entire talisman to carry more Spiritual Energy, thereby achieving better defensive effects.

Although this enhanced version of the Spiritual Shield is slightly stronger than the ordinary Tier One Body Protection Talisman, it is still far inferior to the upcoming second-generation Spiritual Shield, which is the Tier Two Body Protection Talisman.

After all, the materials required for Tier Two talismans are completely different, and their effectiveness cannot be resolved simply by optimizing a few runes.

At the same time, due to production issues, these enhanced Spiritual Shields have not been fully popularized and are temporarily distributed to some assault units. Given their defense effect is neither outstanding nor inadequate, everyone casually started calling it the 'One-and-a-Half Generation'.

This is just like the Type 38 manually-operated rifle being called 'Three-Eight Big Lid', J-8 being called 'Master Eight', and DB-28 being called 'Big Plate Chicken', which are colloquial names that roll off the tongue.

A few minutes later.

Two engineers, clad in bomb suits, arrived at the side of the hidden compartment with the strengthening of the 'One-and-a-Half Generation' and started drilling at the designated location.

"Ka ka ka——"

The drill made a sharp collision sound on the ground, and after about a minute or so, the two warriors wearing heavy bomb suits gestured to Zhang Yaqing, indicating that they had opened the hidden compartment.

Then chemical defense soldiers quickly stepped forward to sample the gases:

"Report, the oxygen content is 3.6%, which is significantly different from the Damo Realm standard of 26%. Judging by the airtight nature of the compartment, the hidden compartment was opened at least three to five years ago—although this figure fluctuates a lot, and even a possibility from ten years ago cannot be ruled out!"

The chemical defense soldier then stepped forward with a flashlight to take a look:

"Commander, there seems to be a passage below!"

"Hmm? A passage?"

Zhang Yaqing muttered in surprise; the situation of the hidden compartment was not quite what he had imagined—in his original expectation, there should have been one or two small boxes beneath the hidden compartment, possibly revealing Spirit Stones or even demon beast crystals.

After all, according to Wei Qiangsheng, this hidden compartment can't be found by ordinary Cultivators and requires strong observational power to discover, so logically, there should be some treasures inside.

Seeing that the situation in the hidden compartment differed from expectations, Zhang Yaqing told Chen Jiasong and others to remain vigilant, while he moved aside to quickly report the situation on the scene to Longxing River.

A few minutes later, he returned to the side of the hidden compartment and said:

"Authorized by higher authorities, the communications team should first send a micro-sensory robot down to examine the situation, then set up a temporary base station to transmit the images back to the command center."

Micro-sensory robots are a concept that fewer students are more familiar with.

In fact, research into micro-sensory robots, which we often refer to as electronic bees, began domestically as early as the early twenty-first century.

However, this technology has always been stuck due to the endurance issue—it's somewhat like Neon's full-scale Gundam model, which looks impressive but is actually just a large model, shaking more than an elderly grandma when it walks.

In the relevant field internationally, Robo-Bee and the Tribot inchworm robot are among the more famous examples.

The locals didn't break through this bottleneck either, but in some special situations, using a double-chamber battery with a potassium ferricyanide cathode to control the micro-sensory robot for short-distance flights is still not difficult.

This technology's civilian limit distance in the homeland is 118 meters, accomplished by the Physical Research Laboratory of Huazhong University of Science and Technology in March 2018.

The military version certainly goes farther, but since it involves sensitive data, it's best to assume it operates like the civilian version.

Once everything was ready, the micro-sensory robot began to start, fly in, and descend.

Zhang Yaqing and others observed the exploration in real-time through a screen.

The passage beneath the hidden compartment was somewhat deep, with an overall length of about fifty meters, and it was curved, somewhat like a spoon.

If the communications soldier had not dropped a relay down using ropes during the process, the micro-sensory robot might have lost signal with the ground due to the layers being too thick.

The width of the passage remained about one meter, and after a few more minutes, the micro-sensory robot finally reached the end of the passage.

Yet, as soon as they saw the scene at the end of the passage, the pores of everyone present almost stood up!

Some warriors even raised their guns subconsciously!

The end of the passage was around twenty square meters of ground, with a ceiling height of three to four meters, composed entirely of yellow soil.

In the black-and-white images captured by the infrared camera, there was a skeleton and an ice coffin clearly present on the ground!

The skeletal frame was pitch black, while the ice coffin was crystal clear.

Even more horrifying was the fact that there was a person lying inside the ice coffin!

Breathing still present, with a lifelike appearance!

Note:

Only one update today because it's this author's birthday, and feeling justified (thunderous voice)!

In the blink of an eye, I'm another step closer to forty...

Being away from home without many friends, I'm contemplating whether to order a cake delivery in the hotel or treat myself to some Japanese food alone.

Speaking of it, it's been more than ten years since I last had a birthday cake.

The loneliness of adulthood...

But remarkably, at 11:53 p.m. yesterday, the total number of subscriptions perfectly reached 7,000, a birthday gift from heaven, perhaps, laugh.
