209: Chapter 214 Unconditional Surrender, True Purgatory

Boom—

The flames surged along the ventilation shafts into the tunnels, weaving through every passageway.

At level five firepower, the Fire Dragon Guard's flame projection distance in open terrain is 200 meters.

However, when the flames surged underground, the narrow tunnels effectively prevented energy diffusion and loss.

The flames moved along the tunnels, reaching over a thousand meters!

The tunnel fortress meticulously designed by the Vietnamese had now turned into a giant furnace, becoming their graveyard!

The raging flames reached deep underground, then proceeded along various channels.

No secret passages, mechanisms, or forks in the road could deceive the flames.

Wherever there was airflow, the flames would roar in, incinerating everything.

Ah—

Heart-rending yet brief and stifled screams echoed continuously in the tunnels.

The Vietnamese soldiers hiding in the tunnels were incinerated into charcoal the very instant they saw the flames and felt the pain.

However, these soldiers who were directly scorched to charcoal by the flames could be said to be the luckiest people in this horrific massacre.

Because those who were lucky enough to escape the burning flames would suffer torment worse than death.

Some soldiers in the tunnels escaped the center of the flames and were not burned to death directly.

However, what awaited them next was not the hope of life, but pain and despair.

After the flames surged, they left behind gelatinous fuel, a fuel known as the "never-extinguishing flame."

They would not kill the enemy directly, but would adhere to the enemy's body and burn continuously, penetrating deep into the marrow.

Soldiers who were contaminated with the gelatinous fuel tried to extinguish it by rolling, but this action only spread the fuel evenly across their bodies.

While leaving behind the gelatinous fuel, the flames also consumed all the oxygen in the tunnels.

Oxygen-deprived soldiers could not help but breathe faster and deeper, but what they inhaled was superheated gas.

As they breathed, these gases poured into their respiratory tracts and lungs, bringing unimaginable pain.

Besides the soldiers in the tunnels, some soldiers were hiding in secret rooms.

After seeing the flames, they quickly closed the stone doors of the secret rooms, successfully avoiding the burning flames.

However, they thought they had escaped death, but in reality, they had missed Su Yang's final mercy.

The flames roared, taking away the oxygen in the tunnels and leaving behind gelatinous fuel in the passageways.

The fuel would burn continuously, consuming all the subsequent oxygen that squeezed in.

Therefore, once the oxygen in the small secret rooms was exhausted, those hiding inside would die from lack of oxygen.

However, this was a way of dying that required good luck; a large number of soldiers would die before the oxygen in the secret rooms was exhausted.

The stone doors could block the flames, but they could not block the high heat left behind by the flames; the high heat would penetrate the stone doors and conduct into the secret rooms, turning them into furnaces.

The gelatinous fuel remaining in the tunnels would continue to burn, constantly maintaining the temperature inside the furnaces.

The soldiers hiding in the secret rooms would endure roasting that was worse than death.

Boom—

"No, no!!!"

"The Dragon Kingdom are not human! The Dragon Kingdom are simply not human!!"

"This is a massacre, this is a slaughter, he will be taken to the war tribunal!!!"

The people in the Vietnamese high-level conference room fell into madness.

They had a bad premonition when they saw the Fire Dragon Guard appear, because units of this size clearly were not meant to enter underground combat.

Watching the Fire Dragon Guard approach the ventilation shafts step by step, their vigilance and unease grew heavier.

Finally, seeing the Fire Dragon Guard spew flames and the fire dragon travel all the way down the passageway, their suspended hearts finally exploded.

In their X-ray view, they could clearly see the situation of the Vietnamese soldiers dying miserably in the flames inside the tunnels.

The fire dragon surged wildly in the tunnels, turning everything in its path into charcoal; even the iron nails in those traps were instantly melted into molten iron.

However, being turned into charcoal and dying in the flames was already the luckiest way to die.

They also saw some surviving soldiers struggling in the gelatinous fuel and wailing in pain in the high-temperature secret rooms.

Heart-rending screams in the tunnels were incessant, and scenes like an Asura purgatory were playing out everywhere.

This is the fate of those who betray, this is the consequence of defying the Dragon Kingdom!

The various high-level officials of Vietnam were in complete despair, and there was no longer any thought of resistance in their hearts.

The power of the Dragon Kingdom's technology and the ruthlessness of Su Yang's methods far exceeded their imagination and far exceeded the consequences they could bear!

"Send a message to the Dragon Kingdom's high command, send a message to the Dragon Kingdom's high command!!" the General of the Military Department of Vietnam shouted, trembling.

"We surrender, Vietnam surrenders unconditionally! Let them stop, let him stop!!"

"We were coerced by the United States, spare our lives, spare our lives!!"

Ah—

Screams came from the passageway above, and Lord Li Sun held a kerosene lamp, trembling continuously.

What happened, what happened?

"Fire! A great fire!!!"

Bang!

The guard rushed in.

"Run! Lord, the fire is rushing in! The fire is rushing in!!"

"How is that possible!" Lord Li Sun grabbed the guard.

"With the water gates in place, how can there be fire, how big can the fire be!"

Lord Li Sun could not believe it; their tunnels had many water-sealed gates at the turns.

These were defensive measures for the tunnels, which could effectively prevent attacks like poison gas and smoke.

How could the flames break through so many water gates and burn to his lowest level?

"There are no more water gates, it's all over!!" The communications officer didn't want to explain further and pulled Lord Li Sun violently.

"Lord, let's go, we will escape through the water well!!"

"Impossible! How could we be finished!!"

Lord Li Sun stumbled out of the command room, and just a few steps up, screams reached him.

Two soldiers, covered in fire and burned pitch-black, ran out from the end of the passageway.

Their skin was already carbonized, tearing as they ran, and the newly exposed muscle and blood were quickly scorched by the flames again.

They screamed heart-rendingly and ran towards Lord Li Sun, like vengeful ghosts coming for his life.

"Ah, ah!"

Lord Li Sun was so scared that he dropped the kerosene lamp in his hand and turned back.

"The well, where is the well..."

Above the surface, the Ranger Troops were responsible for dispersing to find ventilation shafts or tunnel entrances.

The Scout used the Radar Detection on the black iron chariot to detect the crowds gathered underground and guide the Fire Dragon Guard to spray fire.

After spraying fire at one opening, the Fire Dragon Guard immediately adjusted its position to continue spraying, ensuring the flames could cover the entire tunnel System of Vietnam.

This was a method Su Yang developed while roasting Zerg caves: the Skyfire Guard clears the way, the Scout reports the points, the Fire Dragon Guard incinerates, and finally, the infantry cleans up the remaining soldiers.

In this operation against the tunnels of Vietnam, out of humanitarian considerations, Su Yang had the Fire Dragon Guard increase the combustion ratio and reduce the gelatinous fuel ratio.

This allowed most soldiers to be directly burned to charcoal by the flames, rather than being roasted alive in the subsequent continuous burning of the gelatinous fuel.

Su Yang sometimes felt that he was still too merciful.

However, while this combat method was efficient and convenient, it was a great waste of resources.

If it weren't for the complexity of the tunnels of Vietnam and the urgency of time, he actually wouldn't have wanted to use this method.

After all, Lord of Yuenan was still down below; dying just like that would really be letting him off too easily.

"Your Majesty, the Scout has detected signs of activity around the water well. Should we kill them directly or..."

"Keep them alive. I want the people who escape from the well alive."

Su Yang's eyes flickered; given the cunning nature of the Lord of Yuenan, he should have left himself a way out, right?
