The strange demon kings discovered by the Flame Demon Emperor were those heroes sent by the undead to assist the Southern Abyss Alliance.

As soon as the Flame Demon Emperor appeared in front of the undead hero, the four giant swords slashed towards its body almost simultaneously, which surprised it that was about to rely on the sudden sneak attack.

As an undead creature, the Death Knight naturally had no emotions such as surprise for a long time. Therefore, although the Flame Demon Emperor appeared very abruptly, it did not make them react in the slightest—especially the Fire Demon Emperor's volcano-like life breath, which was obviously incomparably superior in the induction of the undead.

Although he was surprised by the swiftness of the reactions of these strange demon kings, the Flame Demon Emperor who took the initiative was naturally not unprepared. A thin curtain of fire had already covered the Flame Demon Emperor when the four Death Knights' giant swords slashed down.

"Whoa-" This thin curtain of fire seemed fragile and vulnerable, but the giant swords of the four death knights were easily cut open as if a curtain was torn apart, and the blade fell on the body of the Fire Demon Emperor—it was indeed vulnerable!

The Flame Demon Emperor had a look of disbelief on his face. Although the fire curtain around it looked weak, the amount of force used was no less than the mouthful of "thick phlegm" that had offset more than twenty demon kings of the Southern Abyss Alliance before. Now it's just a blow from four strange-looking demon kings, and it's actually been cut like this?

Luckily, it's the essence that is concentrated. The body of the Flame Demon Emperor has shrunk from the size of a small mountain to only about ten meters tall now, and the armor on his body, which originally looked like a black rock texture, has also changed, exuding the color of crystal, and it looks very strong.

"Dang Chang—" Four giant swords slashed down at the same time. At the same time, it was also bounced high. The Fire Demon Emperor retreated backwards. He looked at the four Death Knights who were only up to his knees.

This is the power of the necromancy! The Flame Demon Emperor was sure in his heart. Only this kind of power corresponding to living beings can ignore the gap in rank to a certain extent, and break through their mythical defenses at an epic level.

Taking a deep look at the strange-looking figures behind the four Death Knights, the Flame Demon Emperor suddenly felt that although his strength had recovered to a level stronger than the previous battle, this battle would be even more difficult.

The Fire Demon Emperor quickly distanced himself from the four Death Knights after resisting the slash of the four Death Knights with the black crystal armor on his body. Of course, this is not to say that the Fire Demon Emperor does not dare to fight the Death Knight in close combat, but it is just vigilant.

But in the face of the edge of choosing to temporarily avoid himself. Retreating to the Fire Demon Emperor not far away, the Death Knights had no intention of letting go.

The arm holding the greatsword was bounced up, but their other hand was raised in unison and clenched suddenly. At the same time, countless green energy ripples suddenly appeared on the body of the Flame Demon Emperor, tightly entangled with it.

From the outside, this seemed to be a bondage-type skill, but only the Fire Demon Emperor himself who had been attacked could feel that a - no, four withering and dead breaths were infiltrating its body pervasively.

The appearance of these four breaths did not have the slightest warning. Let the Flame Demon Emperor also have no choice but to be tricked. Fortunately, after all, he was a mythical powerhouse, and the Fire Demon Emperor quickly sprayed all over his body. Shoot. Out of a golden flame. Dispelled those dark green ripples of energy.

However, the Fire Demon Emperor could feel it, and although his response was quite timely, some of those withered and dead breaths had already invaded his body, bringing some damage to it.

Yu Fei, who was paying attention to the battle situation on the side of the Lava Realm through Illidan's perspective, focused his attention on the side of the Fire Demon Emperor, and naturally saw this scene. And he, unsurprisingly, recognized the dark green energy attack suffered by the Flame Demon Emperor, which was the death entanglement of the Death Rider.

The Fire Demon Emperor's face was calm, but his heart had already set off a monstrous wave. Could it be that the time of prophecy is approaching? The necromancy has appeared, and destruction is far away?

However, no matter how shocked it was or what it was thinking, the undead heroes would not stop attacking. The four Death Knights had just used Death Coil and had lost the means of long-range attacks. The skeleton war horses under them all shook their hooves and rushed towards the Fire Demon Emperor.

And the first to arrive before the death knight is the attack of other heroes.

On the ground in front of the Flame Demon Emperor, which was originally relatively flat, spikes suddenly appeared, and they spread to its feet in a very short time. And these spikes, which were only very short when they spread, suddenly rose up when they came to the feet of the Fire Demon Emperor, and bounced the Fire Demon Emperor fiercely.

The Flame Demon Emperor only felt that his mind was suddenly blurred, and he fell into a state of vertigo. However, as a mythical-level supreme powerhouse, its resistance to this negative state is still considerable, and it has already sobered up when it falls.

It's a pity that these spikes are more than just a wave. As soon as the Fire Demon Emperor fell, another spike that spread over it bounced high, sending it into the air again, and at the same time falling into a brief state of vertigo.

Similarly, when it fell again, a third wave of spikes arrived, sending the Fire Demon Emperor into the air again. This time, however, it finally learned to behave, and when it recovered from its vertigo and fell, it flew up and was no longer standing on the ground.

Looking at the spikes that bounced up again on the soles of his feet, even though the Flame Demon Emperor was a hot Flame Demon, he couldn't help but shed a trace of cold sweat. Immediately, it turned its angry gaze on the source of these spiked attacks, the four demon kings who resembled beetles.

Compared to the four death knights, there was no sense of necromancer in the aura of these beetle-like demon kings. It's just that compared to the Death Knight, who brought a little damage to himself, the Fire Demon Emperor hated these beetle-like demon kings more - the spikes that bounced it away one after another were too shameless.

It's just that the undead heroes don't attack just that. Just as the Flame Demon Emperor set his gaze on the four beetle-like Demon Kings, that is, the Crypt Lords, four green energy waves had already flown in front of the Flame Demon Emperor.

However, compared to the Death Knight's attack, these four rancid bee swarms did not make the Fire Demon Emperor feel any threat. And its judgment was no longer wrong, and the fire curtain that it had spent a lot of effort to lay could easily withstand the attacks of the Dreadlords.

However, after dealing with the attacks of the Crypt Lord and the Dreadlord King, the four Death Knights in a row rushed in front of the Fire Demon Emperor again. Although the Fire Demon Emperor had already flown into the air, this pair of Death Knights, who had already reached epic level, could not pose a problem.

In the process of charging, the front hooves of the skeleton war horse no longer fell to the ground, but stepped in the air, and flew like this. Although there was no sound of horses' hooves, the momentum of the four death knights charging did not diminish in the slightest, and the four giant swords that exuded an icy aura also fell towards the Fire Demon Emperor.

The Fire Demon Emperor was disdainful in his heart, although the attack of these necromants would cause him a little damage, but it was only a little. Besides, hadn't they seen the speed at which they had almost teleported from the middle of the basin just now?

Not wanting to be attacked by the necromantic aura again, the Fire Demon Emperor immediately prepared to withdraw and retreat. However, a low murmur suddenly appeared in its ears. As soon as he heard this murmur, the Fire Demon Emperor felt a sense of distress.

Well? Problematic! The Flame Demon Emperor shook his head, trying to get out of this predicament. However, the murmur quickly became four, echoing in its ears.

It stands to reason that the four voices sounded at the same time, and it would seem extremely chaotic, but to the ears of the Flame Demon Emperor, the rhythm of these four murmurs was extremely strange and not chaotic at all. On the contrary, they seem to have the same root and origin, and they are increasing from each other.

As the voice echoed in his ears grew stronger, the Fire Demon Emperor finally failed to resist the feeling of distress emerging from the depths of his soul, and fell into a sleep—and in front of him, four giant swords were being chopped down. (To be continued......)
