A large number of bundles of bundled explosives were buried under the predetermined location, covered only by a thin layer of sand and gravel.

This big pit was made by an earth magician who used magic to sink into the ground, and it didn't take long.

After firing the palm cannon, Owen immediately controlled the armor and turned around to accelerate towards the north wall.

Before the Black Dragon King fell to the ground, the energy light speed cannon penetrated the layer of sand and gravel and detonated the explosives inside.

Rumble——

With a deafening bang, a huge ball of flames and black smoke suddenly rose from the ground, and a large amount of gravel and iron pieces also spewed out, completely engulfing the Black Dragon King's body in an instant.

Immediately afterwards, strong shock waves and explosions reached the northern city wall one after another.

The soldiers covered their ears and lay prone on the ground to avoid the debris and iron pieces that might fly over.

The large amount of black smoke produced by the explosion formed a mushroom cloud as it rose, and it did not dissipate for a long time. There was a rain of gravel and iron flakes all around.

Angelica's mount was frightened again, and she had to comfort the Pegasus and fall behind the city wall, temporarily leaving the battlefield.

After the shock waves and explosions passed, the soldiers in the trenches quickly got up and stuck their heads out to observe the battle situation.

Due to the protection of the armor, Owen was not greatly affected when escaping.

Flying over the city wall, he turned around and hurriedly asked about the situation in his mind.

[Alfa, can this explosion severely damage the Black Dragon King? 】

[Based on the data obtained on the target and the analysis of the amount of black powder, an explosion of this magnitude has a 99% probability of causing minor injuries to the target. 】

【Is it only a minor injury? 】

After hearing Alpha's prediction, Owen couldn't help but frown. Using so much black powder could only cause minor injuries. The Black Dragon King's skin was really thick.

Ouch——

Sure enough, a roar came from the black smoke, and the Black Dragon King used his magic power to form a strong wind that blew away the surrounding black smoke, revealing his figure, staring angrily ahead.

After receiving the explosive attack at such a close distance, the dragon wings on the back of the Black Dragon King were in tatters, and the dragon scales on the lower body were damaged in several places, and red dragon blood flowed out.

We have to quickly enter the next combat stage, but Owen only knows the basic operations of the armor and doesn't know how to unleash this ultimate move.

[Alpha, how to use the charged ion cannon?]

[Please make fists with both hands straight and close them in front of your chest.]

Owen obeyed and did as he was told. The armor's arm immediately deformed, and a pillar protruded from the chest. Then it split into four thin pillars, which were assembled together with the arm to form a huge ion cannon launcher.

It started to accumulate energy, and a spherical blue ion ball formed in the middle of the barrel. The four thin pillars released countless tiny blue lightnings, which continued to gather towards the ion ball.

Countdown, thirty seconds.

The Black Dragon King flapped his dragon wings and wanted to fly again, but suddenly found that the dragon wings behind him were already in pieces.

It had no choice but to move its limbs and crawl towards the north wall with anger.

"Full firepower output!" Viscount Jarvis ordered loudly.

Lusha who was under the city wall also issued the same order, and then he also raised his musket and shot at the Black Dragon King.

Bang! Bang! Bang!

Up and down the city wall, two large hails of bullets hit the Black Dragon King.

The Black Dragon King is not within the effective range of the musket? It doesn't matter, just shoot, there is only one enemy anyway, and he is so big.

Faced with a salvo of hundreds of musketeers from the entire army, with so many bullets flying past, and exchanging quantity for hit rate, many bullets will definitely hit the target.

The artillerymen were also loading the next shell quickly.

boom!

A bullet hit the dragon scale near the Black Dragon King's left eye. It failed to penetrate, but sparked a spark.

Realizing that someone was deliberately attacking his eyes, the Black Dragon King became angry.

Facing the overwhelming bullets flying in front of it, it didn't see clearly where the bullets just came from, so it opened its dragon's mouth and breathed out dragon breath.

Shaking his head left and right, the flying bullets quickly turned into copper water and fell to the ground when they passed through the dragon's breath.

I thought the dragon's breath could reach the bottom of the city wall, and the soldiers in the trench shrank and fell down in fear.

But it didn't happen. The dragon's breath was still some distance away from the city wall.

Seeing this, Lusha yelled: "It can't hit us, keep shooting!"

Upon hearing the order, the soldiers who had loaded their bullets quickly stood up from the trenches, raised their muskets and continued to shoot at the Black Dragon King.

Bang! Bang! Bang!

The first salvo was the time when the number of bullets was the largest. After that, due to the varying loading efficiency of the soldiers and a few firing failures, the bullet density suddenly dropped.

Probably aware of this, the Black Dragon King took back his dragon breath and continued to climb towards the north wall at a faster speed.

No matter how many bullets hit him, the Black Dragon King's dragon scales can completely block them, but there are too many of them, so the bullets will hurt a little bit.

This little pain is nothing to the Black Dragon King. It just wants to kill those hateful humans in front of it, kill them all!

The huge Black Dragon King's crawling speed on the ground was not bad. After a while, it crawled to a place where it could use its dragon breath to attack humans.

Raising his head, the Black Dragon King opened his dragon's mouth, black flames burst out from the depths of his throat, and he was ready to breathe out dragon breath.

Seeing this, Lusha yelled again: "Hide quickly!"

Bang!

Below the city wall, the fastest artillery group loaded the shells and decisively fired the second bombardment.

The cannonball hit the Black Dragon King's abdomen, and its power was not at the same level as a bullet. It was painful and the dragon's breath was interrupted.

Ouch——

The Black Dragon King roared again, preparing to breathe dragon breath again, and the target of the attack was its most hated artillery.

"Run quickly and jump into the trench!" the squad leader who operated the artillery shouted to his teammates.

Black flames shot out from the dragon's mouth and hit the cannon directly, melting it into molten iron.

"Ahhhhh——"

The nearby trenches were unable to escape the scorching heat of the dragon's breath. The soldiers inside screamed in pain and were soon roasted alive to death.

Damn it! There are still five seconds left! Owen was so anxious in the air that time seemed to pass so slowly.

At this moment, McGrady, the sniper ambushing in the Sky Mountains, pulled the trigger.

boom!

A bullet flew accurately and hit the Black Dragon King's left eye.

Ouch ouch——

The dragon's breath was interrupted again, and the Black Dragon King was blind in his left eye, bleeding with dragon blood, shaking his head crazily, and letting out painful dragon roars.

Then, it endured the pain, turned the dragon's head, and looked somewhere in the Tianqiong Mountains with its right eye.

This time, the Black Dragon King found the location of the attacker.

Feeling the Black Dragon King's gaze, Maddie felt a chill behind her and said to Izzy urgently: "Run!"

One second left!

The Black Dragon King originally wanted to hunt down the human who shot his left eye out, but an inexplicable sense of danger quickly rose from the bottom of his heart. He suddenly raised his head and looked at Owen.

Time is up.
Chapter completed!
