Deep in the night.

The pitch-black Black Mountain Pass, with not a soul in sight on the entire street.

All that remained were patrolling soldiers and the night watchmen.

As early as two years ago, when Wu Country and Great Yu went to war, a curfew had already been instituted in Black Mountain Pass.

After 7:00 PM, anyone wandering the streets was either a soldier of Wu Country or a spy of Great Yu!

And tonight was destined to be an extraordinary night.

At 1:00 AM, when the night watchmen were already resting, more than a dozen silhouettes suddenly emerged from some small alleys.

They were clearly assigned, moving towards their respective predetermined directions.

Some people even carried firewood, sulfur, and other items, quickly traversing the alleys.

What they didn’t know was that inside several rooms on the periphery, large numbers of fully armed Wu Country soldiers, clad in armor, were hidden!

The leader was a man in a blue robe, continually tapping a folding fan against his other hand.

“Lord Qiann, are we not acting yet?”

A soldier asked softly, with an eerie tone.

The man named Qian shook his head and said, “No hurry, our ‘Feiyan Forest’ has found out that Xu Mujun plans to raid Black Mountain Pass tonight, intending for the Great Yu spies to set the place ablaze. I’m rather keen to see what means they will use?”

“General Turga has already gathered all elite soldiers on the city walls, just waiting for the Great Yu army to fall into the trap.”

“Hmph!”

The soldier snorted coldly, “What Grand General of Great Yu, aren’t they pinned down firmly by us at Black Mountain Pass.”

“Even if Xu Mujun is powerful, how can he charge into Black Mountain Pass alone?”

“Our Black Mountain Pass is as solid as a rock, even if given a million soldiers, they cannot take it down!”

The man surnamed Qian shook his head, pondering how Great Yu planned to launch a surprise attack tonight?

Black Mountain Pass!

That was a strong city established in a mountain pass of the Yin Mountain, entirely constructed from massive stones transported from the Yin Mountain Range, mixed with rice slurry inside, incredibly sturdy.

Unless… they dig a tunnel?

He shook his head.

The entire area beneath Black Mountain Pass was as solid as a single mass, how could Great Yu possibly dig through it?

“Fire! Fire!”

Just then, a frantic shouting came from outside the door.

Along with it, a large number of figures rushed out of the room, hurriedly carrying water to extinguish the fire.

Those who remained in Black Mountain Pass nowadays were mostly people associated with the military, hence the fire was quickly brought under control.

But suddenly, there were over a dozen fire spots within Black Mountain Pass, waking nearly half of Black Mountain City.

The man named Qian immediately said, “Everyone, hold your positions, don’t rush out to put out the fire.”

“Yes!”

“Feiyan Forest!”

More than a dozen figures quickly stood out. As spies of Wu Country, they were all elite in the Wu Country army.

“Go, capture a few tongues, let’s see what they’re up to, and hopefully we can find out their target for the sneak attack.”

“Yes!”

More than a dozen people quickly chased after them, soon capturing two Great Yu spies who had just set fires.

After some severe interrogation, however, no useful information was obtained, causing the man named Qian’s face to change immediately.

“Not speaking? Or perhaps… they don’t know either?”

The man named Qian frowned and said, “Inform General Turga, Great Yu’s attack is coming soon, tell everyone to hold their positions, don’t move recklessly.”

“Yes!”

“What exactly are the Great Yu spies up to?”

“And from where exactly will Great Yu’s attack come?”

“Tunnels? Impossible, the underground is solid rock, entirely undiggable.”

“The two mountain flanks? That’s impossible too!”

“The mountain paths are treacherous and impassable for large armies, and I’ve built numerous arrow towers on both sides of the mountain paths. If Great Yu’s army dares to come, they will surely be completely destroyed!”

“Then from where can they launch an attack…?”

Inside Black Mountain Pass, everyone was waiting for the surprise assault from the Great Yu army.

And those more than a dozen fires, risking the exposure of over a dozen Great Yu spies’ identities, even their lives, were gradually being extinguished.

No one noticed, in the direction above the southern side of Black Mountain Pass, large balloon-like figures resembling raindrops were slowly drifting over.

Those were… hot air balloons!

Along with the gentle breeze, the clouds were blown away, revealing the bleak white moonlight.

One by one, the enormous hot air balloons slowly exposed their true appearances.

On one of the hot air balloons, Chen Hongxiu looked at the sprawling dark city below, where a dozen or so flames flickered faintly, and immediately said: “We’ve reached the target, commence the attack!”

“Yes!”

A messenger beside him immediately answered, then lit two torches, beginning to wave them in the air.

Signal flags.

In the dark night, only the torches could be used for communication.

Meanwhile, the others quickly took out one by one thunderbolts, the size of melons, from nearby wooden crates, cautiously handling them.

Each hot air balloon had about ten people aboard, and each time they tossed ten thunderbolts out, pulling the fuses out before casually tossing them down.

These thunderbolts have been specially crafted, with lengthened fuses set to burn for about ten seconds.

Now, from an altitude of at least three to four hundred meters above Black Mountain Pass, the shock wave from the explosion couldn’t possibly injure them.

In an instant, no less than a thousand thunderbolts rained down from above, fiercely crashing into Black Mountain Pass.

“Boom!”

“Boom boom boom boom boom boom boom boom boom…!!!”

Immediately, endless explosions resounded within the entire Black Mountain Pass.

“Boom!”

“Ah!”

“Celestial Thunder! It’s Celestial Thunder!”

“Rumble!”

“An earthquake!”

“Explosion!”

“There’s an immortal…!”

“Ah!”

In an instant, the sounds of explosions, screams, and collapsing buildings erupted from within Black Mountain Pass.

Looking into the night, a series of violent explosions erupted above the entire Black Mountain Pass, flames shooting everywhere.

Whether it was soldiers hiding in houses or people patrolling and putting out fires in the streets, everyone was dizzy from the series of explosions.

Most of the people were blown to pieces by the thunderbolts, while more were crushed beneath collapsed buildings, screaming as they were turned into minced meat.

As for the Feiyan Forest spy organization hidden in the houses, and Wu Country soldiers still stationed on the walls waiting for Great Yu’s army to launch a sneak attack, their losses were even more severe.

The first bombing target Chen Hongxiu and his men aimed for was the southern wall of Black Mountain Pass!

Only by blowing a hole in the wall could the Great Yu army advance directly and capture Black Mountain Pass.

“Boom boom boom boom boom boom boom boom boom…!”

The continuous explosions kept resonating, as if the entire Black Mountain Pass, with hundreds of thousands of people, were setting off fireworks together.

On the south side of Black Mountain Pass, the well-prepared Great Yu army was unexpectedly paralyzed with fear at this moment.

Especially the two dozen generals leading them, who stood there with mouths agape, dumbfounded at the sight of the distant Black Mountain Pass and the soaring flames.

“Heaven’s punishment?”

“Immortals aiding us!”

“Our Great Yu is actually assisted by immortals!”

“Such…such powerful weapons…”

Wujun was so frightened that he fell off his horse, trembling as he knelt on the ground: “Celestial thunder descends! Divine beings! They are all divine beings!”

At this moment, he showed none of the arrogance he had displayed in the military tent the day before.

At the front of the crowd, Zhao Tieshan, who had been waiting for a long time, shouted loudly: “What are you waiting for, move towards Black Mountain Pass quickly!”

“Fifteen minutes! I agreed with General Chen that the Thunderbolt would cease in fifteen minutes…”

Xu Mujun flung his cape, his long sword pointed towards Black Mountain Pass.

“The whole army, attack!”

“Boom…!”

Under Xu Mujun’s command, fifty thousand Dragon-soaring Army soldiers immediately mounted their horses and charged towards Black Mountain Pass.

Other troops also moved out, marching towards Black Mountain Pass.

At this moment, the morale of the Great Yu army was exceptionally high.

With the aid of celestial thunder, tonight they must take Black Mountain Pass!

Meanwhile, inside Black Mountain Pass, some of the Wu Country troops, who had been bombarded, began to react, looking up towards the sky.

After all, Black Mountain Pass was large, and with mountain slopes on both sides, along with inaccurate aim and the hot air balloons in constant motion, there were areas that Chen Hongxiu and others couldn’t bomb.

“In the sky! Look at the sky!”

“What the hell is that!”

“There are people up there! They’re dropping things down!”

“Celestial thunder?!”

“Immortal?”

“There are cultivators!”

Inside Black Mountain City, an old man with a black beard suddenly appeared on a rooftop, glaring at the Thunderbolt falling from the sky.

Yin Mountain Ancestor!

“Magical artifact of cultivators? A semblance thereof?”

“Send orders! Bring the archers over to shoot down those damned things!”

“It’s impossible, Grand General, those damned things are too high, the archers simply can’t reach!”

Inside Black Mountain Pass, chaos reigned, yet the Yin Mountain Ancestor kept his eyes fixed on the hot air balloon moving across the sky.

His figure shimmered and transformed into a phantom darting towards the mountain peak on the left.

His whole body moved through the forest like a panther, swiftly reaching the top.

He took a deep breath, his robes billowing without wind, and then, with a tap of his foot in the air in front of him, he soared into the sky like a great bird.

Within moments, he flew over a hundred meters high!

This height had already reached the flying altitude of the hot air balloons.

He swooped effortlessly onto the hot air balloon like an eagle.

“Hmm? Made of animal hide, with people hanging below? The things in their hands are the explosives? Immortal magical artifacts?”

“Someone!”

“Enemy attack! Enemy attack!”

The soldiers in the balloon’s basket from the Divine Strategy Camp immediately spotted the Yin Mountain Ancestor’s presence, but they hadn’t brought weapons, opting instead to carry more Thunderbolts.

They could only watch as the Yin Mountain Ancestor descended, effortlessly slaying several people in the basket!

“This is what caused the explosions in Black Mountain Pass?”

He picked up a Thunderbolt and examined it closely, a suspicious look in his eyes.

“No fluctuation of innate qi, just a lump of iron? What on earth is this?”

“Sizzle…”

Suddenly, his ear twitched, seeing a Divine Strategy Camp soldier whose chest he had smashed lying sprawled in the basket, covered in blood, but his eyes locked onto him.

He was clutching a Thunderbolt in his arms, and his right hand had already pulled the fuse!

For some reason, seeing the fast-burning fuse, the hair on the back of the Yin Mountain Ancestor’s neck stood up.

“Die!”

His face changed dramatically, and in an instant, using a single foot on the ground, he quickly leaped out of the basket.

Seconds later, the Thunderbolt detonated violently, setting off the remaining dozen Thunderbolts in the basket.

“Boom boom boom boom boom boom boom boom boom…!”

In an instant, a dazzling firework exploded in the sky!

“Damn it! This thing is indeed peculiar!”

In mid-air, the Yin Mountain Ancestor’s body plummeted rapidly, still clutching a Thunderbolt.

“If I can bring this thing back to the Imperial Court, my Wu Country will also…”

Just then, a blade light suddenly appeared before him, striking at his neck with lightning speed.

“Xu Mujun!”

He roared angrily, retreating explosively, while grabbing an odd crescent-shaped curved blade, barely blocking the attack.

“Yin Mountain Old Ghost!”

In the darkness, Xu Mujun swiftly shot forward, his eyes filled with murderous intent.

“You have been hiding in Yin Mountain before, and I couldn’t do anything to you, but today you will leave your head here!”

“Hmph!”

The Yin Mountain Ancestor sneered coldly: “Both of us are innate, we’ll see who lives and who dies!”

“Boom!!”

Just then, a more intense explosion erupted, along with countless cries of alarm.

“The wall has collapsed!”

“The city wall has collapsed!”

“The Great Yu army! The Great Yu army is here!”

“Retreat quickly…!”

“Attack!”

“Smash Black Mountain Pass!”

“Smash Black Mountain Pass!”

The Yin Mountain Ancestor suddenly turned back: “Xu Mujun, you weren’t alone after all!”

Xu Mujun raised his long saber, saying coldly: “Today I will let you know, that being innate and being innate are not the same.”

“Hundred Battle Blood Slaughter Saber!”

“Boom!”

Blood-colored sword qi exploded violently.

The surrounding forest’s trees, flowers, and grass withered rapidly under the blood evil qi, turning into ashes.
