206: Chapter 211 The Underground Fortress, the Confidence of the Yonan People

In the lush jungle, Vietnam engineers were working in full swing.

They were setting up various traps in the jungle: bamboo stakes, iron spike traps, pressure-activated landmines, and tripwire mines.

These traps were placed every few meters, using soil and vegetation as cover, making them extremely well-hidden.

"Lord, 5,000 landmines have been laid, and various iron traps have been covered!"

Beneath the dense jungle, Lord Li Sun sat in the command room of Vietnam's massive underground System, listening to the message.

"Send another squad back to check the guidance markers on the road. Once finished, all personnel are to enter the tunnels and prepare for battle!"

Hanging up the ground communication, Lord Li Sun connected to the command units at various levels one after another, ordering them to enter a state of combat readiness.

After hanging up, Lord Li Sun revealed a confident smile.

As experts in tunnel warfare, Vietnam possessed a unique tunnel civilization trait.

The speed of constructing underground facilities was increased, resource consumption was reduced, and underground defensive facilities were reinforced.

However, because the tunnel System was primarily a defensive measure, this powerful ability of Vietnam was not very popular in the Forbidden Area Trial, which advocated for external expansion.

In the first two rounds of the Forbidden Area Trial, Vietnam had no opportunity to showcase their powerful tunnel warfare technology.

But today, they would hold back the main force of the Dragon Country and use this to once again demonstrate to the world the wisdom of the Vietnamese people and the power of Vietnam's tunnel warfare capabilities!

Back in the day, the Vietnam Senior almost single-handedly dragged down the arrogant United States and subsequently dealt a heavy blow to the invading Dragon Country.

They relied on the spirit of heroic resistance, tunnel tactics full of wisdom, and the favor of the Jungle God.

Now, he, Lord Li Sun, would replicate this feat once again in the Forbidden Area Trial.

What if they have a powerful army? What if they have powerful firepower?

Utilizing the terrain, utilizing the environment, and utilizing wisdom—these are the decisive forces.

Today, he would let those arrogant Dragon Country bastards witness what the wisdom of the Vietnamese people is!

Lord Li Sun lightly patted the wall of the conference room; these fortifications, reinforced with Vietnam's advanced technology, were extremely sturdy.

This massive tunnel System spanned nearly 5 kilometers, and the deepest command post reached 12 meters underground.

The tunnel System was divided into four levels based on function and depth.

The first level consisted of numerous traps located above ground, as well as extremely well-hidden tunnel entrances, exits, and observation points.

Originally, most of Vietnam's traps were hunting traps and some improvised explosive traps.

But with the support of the United States' command points, they were able to intersperse landmines among a large number of improvised traps.

These were hidden killers capable of instantly destroying heavy tanks; just this ground level alone would be enough to give the Dragon Country troops a hard time.

Moreover, apart from the landmines, Vietnam's improvised traps were no child's play.

Although these nightmares that once plagued American soldiers could not cause effective damage to the Dragon Country soldiers wearing steel armor, it was very easy to use them for containment purposes.

And when the Dragon Country infantry soldiers, after enduring great hardships, passed through the surface defenses, they would discover that the nightmare had only just begun.

The second level was located 3 to 5 meters below the surface, where the top-level tunnel passages were distributed.

The tops of the passages were all triangular or arched and reinforced with anchor bolts.

These sturdy defensive facilities could withstand 50 tons of pressure and the bombardment of bombs weighing hundreds of kilograms.

Even with Dragon Country's current firepower, it was impossible to directly break through such hard fortifications.

Unable to blast through the fortifications, the Dragon Country soldiers would have to enter the tunnels as individual soldiers.

Then they would find that the tunnel entrances were extremely narrow, with an average height of less than 1.6 meters, allowing only their Vietnam soldiers to move through freely.

To go deeper, they would have to widen the tunnels while advancing, which would take a lot of time.

Furthermore, the tunnel System was extremely complex, with various forks and traps, making it very easy to get lost or fall into a trap.

Next was the third level, located 5 to 10 meters underground.

As the living and combat area for Vietnam soldiers, the level of complexity here would rise to another level.

While traversing this level, they would not only suffer from various large-scale traps but also face endless attacks from Vietnam soldiers in the darkness.

The harassment from soldiers would make them irritable, the various traps would keep them on edge, and the endless darkness would fill them with fear.

Combining these three, even with the strongest armor protection, the soldiers inside would fall into a breakdown.

This was the wisdom of their Vietnam warriors: not only to attack the enemy's body but also to attack the enemy's mind.

Finally, the fourth level, located 10 meters and below underground, was where the command room, granaries, and various logistical points were located.

This would be a protracted war, and they would entangle themselves with the Dragon Country bastards here for a long time.

A powerful logistics force was an important guarantee for them in fighting against the Dragon Country.

The support from the United States, plus Vietnam's own storage, allowed them to hold out underground for a month.

The Dragon Country troops had traveled a long distance and were unfamiliar with the rainforest environment; obtaining food would definitely be a serious problem for them!

Zzz---

The walkie-talkie sounded.

"Lord, the guidance route has been set up, and we are returning to the fortifications."

"Equip every squad at the observation points with a communication team; I want them to report the miserable state of the Dragon Country in real-time!"

"Yes!"

The walkie-talkie turned off, and Lord Li Sun leaned back, letting his upper body sink into the darkness.

He interlaced his fingers, and his lips curled into a slight arc.

"The show begins."

...

Vietnam high-level conference room.

Under normal circumstances, the Forbidden Area Trial live broadcast screen would follow the Lord, providing a top-down, semi-god's-eye view.

When the Lord was located underground or in a building, the perspective could produce an X-ray effect, penetrating the soil to lock onto the Lord.

Because of this mechanism, the officers watching the broadcast could intuitively view Vietnam's massive underground System.

Viewing their own tunnels from this perspective was also a fresh experience for them.

"As expected of our tunnel System! This level of complexity, this level of detail—it is absolutely the Peak of human craftsmanship!"

"Can a slightly longer wall built on the ground be considered one of the Seven Wonders of the World? Our tunnels are the true light of humanity!"

"Even if the Dragon Country is strong, it will take them at least two weeks to break through our tunnels. In two weeks, their home base might even be taken out."

"It's hard to say about their home base, but at least Australia will surely be able to return to the Three-Party Alliance; by then, they will suffer huge debuffs."

"I'm just afraid they won't dare to fight to the death and will tuck their tails and return to their territory at the slightest setback."

"Impossible. With the self-righteous and arrogant attitude of the Dragon Country bastards, they will absolutely not easily accept the outcome of failure."

"Indeed, in their eyes, we might just be a bunch of uncivilized monkeys; they definitely won't be willing to accept a setback!"

"Hehe, the Dragon Country originally had a chance to win this round of the trial, but it's a pity they ran into us."

"They even want to turn the whole world into vassal states; what era do they think this is!?"

"Even if we are defeated, Vietnam will never become a slave!"

"Kill them; this will become the opportunity for our rise!"

...

Boom---

The dark iron heavy armored vehicle moved forward along the path, the sound of its massive engine echoing over the jungle.

According to the Scout's reconnaissance, the Vietnamese not only did not hide their withdrawal route but even provided many guides, as if they were worried they wouldn't be able to find them.

Su Yang expressed his confusion about this; were these people in such a rush to reincarnate?

"Enemy stronghold detected; the stronghold has entered the range of fire."

The Scout in front sent back detection images, with dense white dots concentrated in one area.

Still playing tunnel warfare? Then let's see if these Vietnamese tunnels are any stronger than the Zerg's.

"Prepare to commence artillery bombardment."

Su Yang ordered.
