After more than ten years of war, the demon army has indeed been tempered into a mature army.

"Fire charge, prepare, fire!"

"Boom, boom, boom......"

Huge fireballs were launched by the bomb carts on the city's head, and smashed down on the rushing monster herd in front of the city.

"Bang!bang!bang......"

In an instant, a dense loud noise erupted, and every fireball that fell to the ground exploded, igniting a fireball with a diameter of dozens of meters, igniting the nearby demonic beasts and demons, burning them to scream.

The fireballs continued to burn, fusing with each other, forming a huge sea of fire, encircling the base of the Demon Expeditionary Army, and immediately blocking the Dark Demon Army into two layers, one layer on one side of the sea of fire, and a larger layer on the other side of the sea of fire.

"Fire charge, fire!"

Immediately afterward, another wave of dense fireballs smashed down from the city, landing on the dark demon army on this side of the sea of fire.

"Ah...... Ah......h

"Whew...... Whew......"

Another sea of fire quickly formed, devouring all these demonic beasts and demons, and the screams came one after another, just this one face, tens of thousands of demonic beasts and demons were given less time by this special flame, and more demonic beasts and demons were injured, the number was no less than 100,000.

In the rear, the four demon lords of Herod, Yezi, Yumu and Ace saw this scene, and their brows couldn't help but lock deeply, and their scarlet eyes seemed to be able to breathe fire.

And Baijie, Ge Tai and Guan Nan have long been accustomed to this, but they don't feel anything.

"Baijie, it's not appropriate for everyone to die like this!" said Herod, with some dissatisfaction.

Baijie's expression was as usual, and he replied: "Humans are good at all kinds of defense methods, if we want to break the city, we can only use the number to consume them in this way, unless we ......"

"Unless what?" asked Herod.

Baijie hesitated for a moment and replied, "Unless the seven of us make a move together......"

Herod's eyes narrowed slightly, and he said coldly: "Then let's shoot together, there is no need for us to let our subordinates make meaningless sacrifices for the sake of meaningless pride." ”

None of the other six demon lords objected to Herod's proposal.

Baijie immediately ordered: "All retreat!"

"Boom ......"

The Dark Demon Army, who had been stopped in the vicinity of the Fire, immediately turned around and retreated to their positions.

Seeing the Dark Demon Army retreating, the Demon Conquering Army at the head of the city couldn't help but be a little surprised.

"No, they're not like that......" someone muttered.

At this moment, the seven figures flew into the air from seven directions, hundreds of meters higher than the walls of the base, looking down condescendingly at the base of the Demon Expeditionary Army, these seven people were the Seven Great Demon Lords.

Although the sergeants of the Demon Expeditionary Army didn't know the Seven Great Demon Lords, they also felt the horror of these seven people at this time, even through the protective array, they could feel that kind of palpitating oppression!

Seeing the Seven Demon Lords appear, Netherworld knew that the situation had begun to develop in the worst direction.

"Hundred stars prosper!"

Nether whispered, he was informing the high-level star gods in the base that they were in the Hundred Stars Commonwealth Array.

The Hundred Stars Prosperity Array, which he set up in order to prevent more than three demon lords from joining forces to attack, was guarded by more than a hundred ninth-order star gods, and could barely exert the effectiveness of a peak star god.

The voice of the Netherworld fell, and more than a hundred bright points of light lit up on the protective barrier above the Demon Expedition Base, like stars.

"Nether, I heard that your formation is good, let's take a good look at it today!" said Herod in a loud voice.

After speaking, he immediately shouted: "Demonization!"

I saw him casually wave his hand and press it forward and downward, and I saw a cloud of black gas erupt from his palm, instantly turning into a huge strange demonic beast and slamming into the defensive barrier below.

"Demonization!"

"Demonization!"

......

The other six demon lords were not idle, and they took action one after another, each sending a huge demonic beast to the protective barrier of the demon army base.

The seven-headed beasts almost covered the entire defensive barrier, and they swung their claws at the same time, clawing hard at the protective barrier.

"Bang ......"

With an earth-shattering bang, the protective barrier shook violently, as if it might break at any moment.

Seeing this, the hearts of the sergeants of the Demon Expedition Army couldn't help but shrink suddenly.

"Firebolt, fire!"

The commander recovered from the shock and immediately ordered a return fire.

"Boom, boom, boom......"

"Boom!Boom......"

A long fire crossbow shot towards the demonic beasts on the enchantment, like a fiery snake, and like a meteor that rolled upside down.

The fire crossbow shot into the body of the seven-headed demonic beast through the protective barrier, but it did not make any sound, as if the seven-headed demonic beast was just an illusion, and the fireballap penetrated their bodies and continued to fly forward.

Witnessing this scene, the Netherworld was not surprised at all, if an ordinary fire crossbow could hurt the demonic beast transformed by the demon lord, then it would be strange.

He took out a long sword.

This sword is four feet and two inches long, the whole body is as black as ink, exuding a faint and extremely cold aura, just by looking at it, it feels like your star soul is going to be frozen!

Holding the long sword in his hand, Netherworld reached out and stroked the blade, and sighed lightly: "It's a pity that this Netherworld Qi can't restrain the demon ......"

With that, he swung his sword and slashed into the air.

"Nether Slash!"

I saw a black sword light flash and disappeared, and most people didn't even see this sword light, because it was too fast.

The sword light passed through the defensive barrier and shot at one of the demonic beasts, but this time it was not like those fire crossbows passing through the body, but shot at the ground, making a soft "poof" sound.

Almost at the same time, the demonic beast that had been hit by the Nether Slash instantly froze...... To be precise, it was frozen, like a pitch-black ice sculpture.

In the next moment, the ice sculpture made a "click" cracking sound, and the demonic beast like a small mountain shattered into countless pieces and rolled down from the defensive barrier.

High in the air, the demon lord Yumu let out a muffled snort, the demonic beast that was slashed by the Netherworld was exactly what he had transformed, and he was obviously injured by the backlash because of this.

Seeing this, Herod shouted in a low voice: "Everyone, the strength of the Netherworld is extremely strong among their nine great gods, everyone doesn't have to keep their hands! Use the Great Demon God to break it in one fell swoop!"

"Okay! Then the Great Demon God!"

"Good!"

“......”

The six demon lords responded one after another, and took out a black weapon that looked like a bone one after another, and began to dance rapidly.

At this time, the demon lord Yumu had already turned into a huge demonic beast again.

"Great Demon God!! the Seven Great Demon Lords shouted in unison.

I saw that the demonic beasts they had transformed suddenly adhered to each other, and then quickly fused, and in the blink of an eye, they turned into a huge monster with seven heads, and the size of a single demonic beast before was also seven times larger.
