The Demon King's nine-foot body, with a dark armor draped over his body, is an extremely conspicuous existence even if he is in the Demon Army Array.

Wherever the demon king passed, the demon soldiers bowed their heads one after another.

Inside the fortress, the attack was immediately suspended, but everyone held their breath, and the target of a crossbow arrow was the extremely dark demon king.

In this secret realm, he is synonymous with extreme darkness.

Really saw the demon king up close, Rao is Pierce was murderous, but he could still feel the coercion emanating from the former, which was not only the suppression that only the strong had, but even implied the nobility of blood.

Whether it is a human race, a demon race, or another race, the bloodline is extremely noble.

Those with noble bloodlines will never have a low status among the clans, and they can even practice powerful combat skills or magic that are limited to bloodlines.

The Demon King is such an existence, and it is precisely by virtue of the bloodline he has that the demon army in the entire secret realm is under his command, and he is also the strongest person in the secret realm.

With each step, the dark fighting spirit unique to the demon clan dispersed into the air with the footsteps.

Pierce clenched the rune sword, he was not sure that he would defeat the other party, but if he allowed the demons to cross the bridge, a few hundred adventurers would definitely not be able to stop the pace of the demon army, and he had to delay the time as much as possible.

"In the hundred years since I took control of the demons, the demons have almost disappeared in the secret realm. ”

The Demon King stopped less than ten meters from the bridge, and in front of him was a mountain of corpses.

"In the past hundred years, we have been recuperating, and the demon army has grown from less than a thousand people to its current size. The Demon King's voice changed, and his gaze shot at Pierce, "But do you know why I chose this time to launch a counterattack?"

Since that battle millions of years ago, the ancient battlefield has been separated from the outside world and has become a space of its own, and only a small number of demons have survived and have always been hidden in this secret realm.

Despite this, after some adventurers discovered this ancient battlefield, they began to suppress and slaughter the remaining demons, on the one hand, they excavated the treasures left in the secret realm, and on the other hand, they directly plundered the demons.

Until the demons were almost extinct here, the secret realm suddenly limited the strength of outsiders, but the aborigines in the secret realm were not affected, but then the human race never gave up, and even sent troops into the secret realm regularly, and the two sides were always on the same page.

But now, things are different.

"A hundred years ago, we were sure to rule this place completely, but so what, we couldn't use the teleportation array at all, and that force also imprisoned us here. ”

The Demon King's gaze shifted downwards and landed on the blood-shining rune sword.

"But I finally waited for this opportunity. ”

"A chance to break the seal!"

The Demon King slammed out a punch, and the dark fighting qi was almost condensed, and the blow formed ripples in the air, and the extreme power caused the space to collapse for a short time.

In the face of this punch thrown from the air, Pierce chose to swing his sword to resist, but the opponent's strength was too strong, although he took the attack with the rune sword, the qi and blood in his body were still surging.

Pierce didn't take a step back, but the Demon King attacked again.

The pitch-black giant sword appeared in the hand of the demon king, and the whole body of the sword was entangled with black fighting qi, and the condensed sword qi was quite visually shocking, like a harvesting weapon in the hands of the god of death.

The Demon King did not use sword skills, but simply swung down the giant sword.

"Heavenly Sword Style. ”

Pierce didn't dare to be careless, the opponent's strength was far above him, not even lower than the fifth-order Golden Knight, although it seemed to be an ordinary sword, he would lose his life if he was not careful.

The demonic flame was attached to the rune sword, and the rune blood light was like a catalyst, and under the drive of murderous aura, the rune sword rushed towards the giant sword with monstrous demonic flames.

Rumble!

Black mist collides with demonic flames.

The Demon Flame is like a reckless beast with its mouth open, trying to devour the Demon King in front of it in one fell swoop.

Compared to the Demon Flame, the Demon King's attack was mediocre, and the black mist-like sword aura in front of him was more like an incomparably small existence.

However, the situation took a sudden turn.

When the demonic flame swelled to the extreme, the black mist began to invade the flame beast like a virus, and the latter struggled painfully to resist, but in just a few breaths, it was completely swallowed by the black mist in reverse.

"It's useless, you're too weak. ”

"You can't harness the power of this sword. ”

The Demon King walked forward, and at the same time, the giant sword in his hand continued to exert pressure, and the black mist solidified the surface of the giant sword, as if it had completed an evolution.

Pierce took a deep breath and slowly tightened his hands on the hilt of his sword.

"Cut off the air. ”

The sword shot out and struck the opponent head-on.

The Demon King's eyes were unblinking, and almost no one could see his movements, and the greatsword had already pinched the time and slashed down before Pierce.

Boom!

The giant sword slashed down on the rune sword, his legs bent due to the tremendous force, and while Pierce was holding the rune sword with his right hand, his left hand was aimed at the demon king in front of him.

"Flame bombs. ”

Swish!

The demonic flame quickly condensed, and in the next second, it flew out.

The Demon King does not dodge or dodge, and allows the flame bomb to hit him.

The impact of the explosion sent Pierce flying, and at the same time freed himself from the Demon King's greatsword, whose tall figure stood tall in the rolling flames.

The left hand that was scorched by the demonic flame leaned forward slightly, and then slashed to the side, and the majestic fighting qi instantly dispersed the demonic flame.

On the dark black armor, there was no trace of being burned, and the demon king himself was even more terrifying, and his body ignored the attack of the demon flame.

"For your sake, I'll give you a good time. ”

Pierce's spirit tightened, the cold hairs all over his body exploded at this moment, and he subconsciously waved his sword with both hands and slashed forward.

Swish!

The Demon King suddenly appeared, and the giant sword was resisted by the rune sword, and the blade deviated from the direction and stabbed Pierce in the side, and the blood immediately stained a large piece of clothing.

Without waiting for him to react, a force had swept him away.

A kite shaped like a broken string fell to the ground, and the rune sword fell into the hands of the Demon King.

The Demon King turned the giant sword behind his back, picked up the rune sword with both hands and looked at it carefully, the blood light in the rune was quickly injected into the former's body, although the number was not much, but the Demon King showed a happy look.

Buzz ~ Long!

Pillars of light shot into the sky from inside the fortress, enveloping the entire fortress within the range of the teleportation array.

The Demon King raised his rune sword, the tip of which pointed straight in the direction of the fortress.

Countless demon soldiers brandished their weapons and roared as they rushed up the bridge.

"Quick, attack them. ”

"It takes time to open the teleportation array, so everyone must hold it. ”

Countless crossbow arrows and stones rose into the air and fell on the charging demon soldiers, and even all the adventurers who were waiting for death, the moment they saw the pillar of light rise again, they also rekindled their hope for life and joined the team to resist the demon army.

However, the demon soldiers rushed up the bridge one after another, and although the trebuchets and ballistas were powerful, they could not stop the boundless demon army.

Seeing that the demon army was about to rush across the bridge, the fortress was in danger.

"I told you I would protect her, right?"

Pierce looked at the bridge in his sight that was crowded with demon soldiers, his pupils shrank sharply, and his right hand took out the only remaining magic core in his body.

The deep green glow contains the purest energy.

It was the one Isabella gave him...... Level 5 Demon Core.
