The soldiers who rushed to the large iron gate at the valley entrance were startled by the dark shadow that crashed down from mid-air.

Immediately afterwards, a series of muffled explosions rang out, and a raging inferno instantly engulfed the space.

Amidst the horrific screams, the more than 300 remaining soldiers of the First Mixed Regiment, including their commander Dubois, who was looking utterly horrified, were all turned into human torches.

What they thought was a safe zone, a blind spot for the fortress's fire, was anything but safe.

Indeed, with Eagle Valley's defenses, how could they possibly overlook such an obvious vulnerability?

Fifty large incendiary grenades turned a 30-meter radius around the valley entrance into a sea of ​​fire.

The soldiers engulfed in flames have lost any chance of escaping.

Incendiary grenades made of aluminum powder and metal oxides will ignite immediately if they get on the skin, and they are impossible to extinguish.

These incendiary bombs can release temperatures of up to 3,000 degrees Celsius in one second, which can instantly melt even armored vehicles.

How could the human body withstand that?

The screams from the flames lasted less than five seconds before being replaced by the crackling and popping sounds of human fat burning.

Soon, the area in front of the valley entrance was transformed into a scorched, dead land.

When the fire was finally extinguished, the more than 300 twisted and deformed corpses had turned into dry, black charcoal...

The third wave of a regiment attacking the fortress had just crossed the 500-meter death zone, leaving behind more than 1,700 mangled corpses.

Less than 300 people remained and rushed to the valley entrance, only to be terrified by the horrific scene before them.

The still-smoking human-shaped charcoal reveals the tragedy that occurred here not long ago.

"These sons of bitches from the mountains actually used incendiary bombs!"

A young officer in a major's uniform muttered to himself, then looked up in horror.

Because another wave of dark shadows crashed down from the fortress.

"Everyone, get out of the way! It's an incendiary bomb!"

The major shouted loudly, trying to alert the soldiers around him.

But it was too late. The insane flames and high temperatures of the incendiary grenade instantly dried up the surrounding air.

Those at the epicenter of the fire will inevitably be burned to ashes...

Thirty minutes later, the sounds of gunfire on the battlefield gradually subsided.

The Kachin Independence Army launched three large-scale offensives, losing 3,800 lives, but still failed to breach the valley entrance.

The defeat in this battle was so swift it was unbelievable.

The 8,000-strong attacking force of the First Division was wiped out in one fell swoop, losing nearly half of its strength. With a 50% casualty rate, the First Division was completely crippled.

Division Commander Wu Nuo stood in the division headquarters, painfully closing his eyes. Several minutes passed before he finally managed to give the order to retreat.

"Order the forward positions to cease their advance. The 3rd Regiment will remain to monitor the situation. All other units must withdraw..."

The ground attack failed.

The Kachin Army's last hope rests on the Black Hawk and Mountain Eagle aerial assault aircraft.

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

At the same moment that the First Division launched its second ground assault, Lin Dong, standing on Eagle Tail Cliff, also heard the buzzing of helicopters coming from the thick fog of the night.

Suddenly, ten fully armed Black Hawk attack helicopters appeared in the pitch-black night sky.

Flashing navigation lights rapidly approached from the northern and southern border of Eagle Valley.

"They're here!"

Lin Dong coldly watched the 10 Black Hawk helicopters fly closer and closer, and calmly issued the signal for the air defense positions to attack.

Three anti-aircraft machine gun positions on the mountain peaks north of Eagle Valley and at the valley's end immediately began a cross-saturation attack on the aircraft.

Long, red dragons of fire tore through the night sky without warning, swooping down towards the oncoming black eagles...

"Alarm! Alarm... Enemy attack!"

"Damn! The enemy has anti-aircraft machine gun positions... Increase altitude immediately!"

"All aircraft lock onto targets and launch missiles..."

......

The helicopter group, which had been so confident just moments before, suddenly descended into chaos.

The Black Hawk attack helicopters in the formation panicked and pulled up and changed direction in an attempt to evade the dense anti-aircraft machine gun fire.

Four Black Hawk helicopters hastily launched air-to-ground missiles, but due to data discrepancies, only one hit its target, destroying an anti-aircraft machine gun.

Under the insane rate of fire of the remaining NSV cliff-mounted anti-aircraft machine guns, the three Black Hawk helicopters were unable to dodge and were hit by dozens of 12.7mm bullets.

The three Black Hawk helicopters instantly burst into flames, billowing black smoke, and spun as they plummeted off the cliff...

"The enemy's firepower is too strong. Quickly raise the level and retreat immediately!"

"Roger that, Black Hawk squadron, withdraw immediately!"

......

The downing of three Black Hawk helicopters extinguished any remaining fighting spirit among the crew members, including the more than 20 Mountain Eagle Special Forces members who survived in the cabin. They all wanted to leave this dangerous place as soon as possible.

However, they underestimated Kunzhai's determination, or rather, they underestimated Lin Dong's ruthlessness.

"Order: RPG rocket launcher combat team, immediately move into the air defense position and assist the machine gun team."

Lin Dong gazed at the brilliant fireworks in the night sky, pressed the communicator, and said coldly:

"Shoot down all the helicopters, not even a single Black Hawk!"

Upon receiving the order, the RPG combat team quickly emerged from the hidden rocks and bushes, raised their rocket launchers, aimed at the Black Hawk helicopters that were trying to escape in a sorry state, and decisively fired the rockets.

Twenty rockets, trailing red flames, whistled as they flew toward Black Hawk, who was dodging anti-aircraft machine gun fire.

"Beep beep beep..."

"Oh no, it's a rocket!"

"Beep beep beep..."

"My machine is locked, take cover immediately..."

......

"Boom!"

"Boom!"

......

In the dark night sky, several more bursts of fire erupted. This time, the Black Hawk helicopter group was not as lucky as before, and five more were hit and caught fire.

The remaining two Black Hawks, with black smoke billowing from their tails, continued to fly, turbulently, attempting a desperate retreat from the battlefield.

However, caught in a pincer attack from both sides by eight anti-aircraft machine guns and 20 RPG rocket launchers, the two Black Hawks did not last long.

Soon, two blazing fireballs fell from the sky, looking from a distance just like two black-feathered eagles on fire...

"Awesome, haha...that's fucking spectacular!"

Feng Zi, who had been standing silently behind Lin Dong, blurted out a curse in excitement, and then said:

"Boss, the Kachin army is in for a rough time this time."

Lin Dong put the communicator in his pocket, his tone calm and indifferent:

"What's there to be happy about? This is just the beginning; the best is yet to come."
