Stop it, the country really can't fit any more bans on the domestic entertainment industry.

Shortly afterward, after confirming that there was no direct radiation hazard or toxic gas residue behind the door that had been violently broken open, Old Qian took a deep breath and led everyone to carefully step over the threshold.

Upon entering the passage, a sense of the times, mixed with dust and a faint smell of gunpowder, immediately hits you.

The air here is slightly cool, as if time has been frozen for more than half a century.

Several powerful flashlight beams swept across the wide passageway.

Soon, everyone's attention was drawn to the images on the walls on both sides of the passage.

On the dusty walls, there were still red paper slogans that had long since faded and were even peeling off.

Although the writing above has been eroded by time, each stroke is still vigorous and powerful.

"Dig deep tunnels and store plenty of grain."

This was a slogan they had often heard before, and it was also the most accurate reflection of that era.

The flashlight beam continued to move forward.

"One for one, one city for one!"

This slogan is full of the ruthless flavor of a strategy that aligns with the idea of ​​exchanging homes.

Let's look further ahead.

There's also a slightly more poetic, yet menacing line: "Dig three thousand feet into the earth, and forge my Heaven-Slaying Sword!"

And that simplest yet most confident statement: "You do your thing, I'll do mine."

........................................

Upon seeing these slogans, the people in the passageway couldn't help but slow down their pace.

These few simple words instantly transported them back to that perilous era.

They seemed to see their ancestors from that era toiling away day and night in this dark and gloomy underground.

Whether they are highly educated intellectuals or ordinary workers with little education.

They all have a ruthless streak in their bones.

They are all using these most straightforward slogans to express their determination to fight to the death against the enemy who destroyed their hard-won peace.

Standing here, everyone seemed to have truly returned to that perilous era.

We have returned to that era when everyone was united in purpose and would rather die than surrender.

Looking at the handwriting, Wang Dafa felt his eyes well up with tears.

Everyone present felt a surge of passion coursing through their hearts.

These are their ancestors.

Never give up.

A ruthless and unparalleled person.

It is said that the Xiong tribe in the north is a warrior nation, but in fact, the Chinese are the real warrior nation.

I ask you, what other country in this world has such terrifying courage to defend its homeland, preferring to perish rather than surrender?

........................................

Amidst the clatter of footsteps, the group's gaze lingered on the slogans for a few seconds before continuing onward.

As the group moved further along, the expressions of the experts and Qian Lao gradually became serious.

Even some of the geological engineering experts had beads of sweat on their foreheads.

As they walked, they kept an eye on the data transmitted back by the instruments in their hands, their steps becoming lighter and more hesitant.

"Stop!"

A geologist suddenly lowered his voice and raised his right hand to signal everyone to stop.

His voice trembled slightly.

Mr. Qian stepped forward, looked at the geological scan map on the other person's tablet, and his brows immediately furrowed into a deep frown.

Based on the experts' comprehensive analysis, the next huge test is coming.

That is a structural collapse.

Although this underground fortification was built to be extremely sturdy, it has been affected by decades of geological changes and constant erosion by groundwater.

At the top of a section of the main passage ahead, the thick concrete layer has been severely weathered, and even large areas of internal cracks have appeared.

Originally, with the explosion-proof door closed, the internal air pressure and humidity maintained a delicate balance, barely preventing that section of the passage from collapsing.

But now.

The sealed door was opened.

The large influx of outside air directly disrupted the original air pressure balance.

This is like a fragile glass bottle that has been vacuum-sealed, which is suddenly shattered.

This change in air pressure may have triggered a chain reaction in the rock strata, causing the severely weathered passage ahead to collapse catastrophically at any moment.

The experts turned around and solemnly warned everyone that from now on, they must be extremely careful.

Do not make loud noises; walk quietly.

........................................

Upon hearing the word "collapse".

Yang Mi, who was standing at the back of the crowd, turned pale instantly.

Her heart skipped a beat.

Is this place about to collapse at any moment?

In that case, wouldn't his nephew Li Mo'an be in danger now?

He was walking right in front of everyone!

Moreover, that kid is always single-minded and doesn't understand what it means to avoid danger; he lacks sufficient awareness of danger.

Almost uncontrollably, a terrifying scene began to play out in Yang Mi's mind.

In the dimly lit passage, hundreds of tons of weathered rocks and concrete blocks suddenly fell from the sky.

Li Mo'an didn't even have time to make a sound before he was instantly smashed into a pulp by the rocks, leaving no trace of his body.

Thinking of this, Yang Mi felt her legs go weak and her eyes reddened.

Not only her, but Teacher Huang and the others also thought of this, and their expressions all turned rather unpleasant.

Under the guidance of the experts, everyone moved about cautiously.

They held their breath as they slowly approached the dangerous section of road marked in red by the detector.

Everyone was prepared to run back at any moment.

however.

When they finally reached the so-called dangerous section of road, they were shining flashlights.

Everyone, including the experts, was dumbfounded.

There was no collapsed earth and rocks.

There were no cracks that threatened to cause it to collapse.

There wasn't even a single piece of gravel that fell from the top.

The road was perfectly intact before them, and the ground was even cleaner than the previous passage.

There is not a single sign that it is about to collapse.

"What? Is the instrument broken?"

An expert patted the detector in his hand, his face full of astonishment and confusion.

Mr. Qian did not speak.

He frowned, his gaze slowly shifting from the smooth ground to the walls on either side of the passageway.

Using the flashlight, he noticed some unnatural reflections on the walls of the passageway.

Mr. Qian stepped forward.

On the dusty load-bearing wall, there were also evenly spaced hoe marks.

The marks seemed chaotic, some high, some low, some deep, and some shallow.

However, when viewed together, they seem to follow a peculiar pattern.

As a top scientific figure who has conducted research in various fields.

Old Qian squatted down, stretched out his fingers and carefully felt the marks for a while, then looked up at the load-bearing structure of the dome.

After a while.

A flash of understanding crossed his eyes, and he immediately realized why the place hadn't collapsed.

He stood up, dusted off his hands, and turned to look at the experts who were still doubting the equipment, as well as the bewildered crowd.

"The instrument isn't broken."

Professor Qian explained to everyone, "Our previous speculations were correct. The structure here is indeed extremely unstable and has reached the point of collapse."

"but......"

He pointed to the hoe marks on the wall, his voice filled with undisguised amazement:

"Li Mo'an has been relentlessly working on this, and he hasn't been doing it randomly."

"With each strike of his hoe, he precisely hit the point where the rock stress in this section of the tunnel converged."

Everyone was completely confused.

Seeing this, Mr. Qian simply bent down and picked up a rather sharp stone from the ground.

He walked to a slightly flattened wall, picked up a stone, and wrote down a series of complex mechanical formulas.

Accompanied by the rustling sound of stones scraping against the wall, Qian Lao wrote and argued as he went:

"Look here, through precise vibration, he released some of the dangerous stress in advance."

"Then, these blows changed the direction of force transmission, forcibly readjusting the stress distribution throughout the rock mass and concrete."

After writing the last line of formula, Qian Xuesen threw away the stone and clapped his hands.

Looking at the wall covered in cryptic writings, he stated with certainty that this method could indeed temporarily maintain the stable structure and postpone the collapse.

Inside the passage, apart from Mr. Qian's voice, no one spoke.

The experts stared blankly at the formulas on the wall, seemingly trying to digest this seemingly miraculous operation.

........................................

but.

The truth is often simpler and more direct than scientific deduction.

In fact, Li Mo'an didn't understand stress distribution at all, let alone what the bunch of symbols on the wall represented.

He knew what to do.

It was simply because when he walked through this area, he felt that the precarious, collapsing roof of the passageway was also a very dangerous explosive device.

After all, a collapse can crush people to death, which is no different from being killed by a bomb.

His thought process is just that unique.

The moment the thought crossed his mind, he knew what to do.

He picked up a hoe and, treating the potentially collapsing passage like a giant bomb, casually "detonated" it.

........................................

At this moment, Yang Mi noticed something different.
