Speaking of which, among the undead heroes, the Death Knight and the Lich can actually cause damage to the Flame Demon Emperor because of their strength attributes. The Crypt Lord and the Dreadlord can only play a role in controlling them for a short period of time with the two skills of Piercing and Sleep.

And in the Molten Realm, the Fire Demon Emperor has constructed a huge energy body. Whether it is the piercing of the Crypt Lord or the sleep of the Dread Demon King, it cannot act on the body of the Fire Demon Emperor, and naturally it can no longer have a control effect.

The four Dreadlords are okay, at least they still have the long-range attack method of the rancid swarm with a short cooldown, and the hellfire they summon has also caused a lot of trouble to the Fire Demon Emperor; The Crypt Lords can only deal with those little fire demons with their own corrosive beetles.

Speaking of which, the strength of the corrosive beetles summoned by the Crypt Lord is not comparable to that of the Little Fire Demon summoned by the Fire Demon Emperor. In addition to the disparity in summoner's strength, the environment within the Molten Realm is also an important factor.

In the Molten Realm, although the Little Flame Demon could not be divided, its strength was even more intense. However, the corrosive beetle's ground-penetrating skill cannot be used in the realm of molten fire, which is the flame, so there is one less means.

If it weren't for the four Crypt Lords who also participated in the battle with the Little Flame Demon, the corrosive beetles under their hands would have been made into roasted beetles by the Little Flame Demon cannon.

Even, seeing that those strange insects were invincible to the little Yan Demon summoned by himself, the Fire Demon Emperor actually divided a part of the Little Yan Demon to contain the Nanyuan Alliance Demon King who was later involved in the Molten Fire Realm, and shared a lot of pressure on himself.

Kel'thugad's face was unswerving. These so-called allies are too bad to play a role in the battle with the Flame Demon Emperor. Fortunately, it didn't expect the Demon King of the Nanyuan Alliance to be. The master's order to it was to have the undead hero kill the Fire Demon Emperor with his own hands.

Casually blasted out another frost nova. Darken the flames of the Molten Realm. Kel'thugad was thinking about what to do next.

The strength of the Fire Demon Emperor was indeed beyond its expectations. The undead heroes, with a few but extremely practical skills, can easily rival the demon kings who are more powerful than themselves in terms of energy.

It's like these clones who have just been promoted to the seventh level of the hero level and can reach the epic level, such as the Death Knight, the Lich, etc., if they really want to put up with the demon kings in the middle and late stages of the epic level, they will definitely not be the ones who fail.

It's just that the Fire Demon Emperor actually possesses a domain skill like the Molten Fire Realm, which Kel'thugad didn't know before. Come to think of it. It couldn't help but be even more disdainful of its nominal ally, the Nanyuan Alliance, and such important news had not been learned in the previous war.

Now it seems that the charge of the Death Knight and the frost nova of the eight lichs alone will not be able to inflict fatal damage on the Flame Demon Emperor.

Kel'thugad could feel that although the Death Knight's greatsword containing necromantic power and the occasional death coil, as well as the Frost Nova of his own lich attribute to restrain the Flame Demon Emperor, every time he hit the opponent, the Flame Demon Emperor's aura was temporarily weakened, but it would soon recover again.

After all, the Lava Realm is the home of the Flame Emperor, and opening the Molten Realm here is as if Illidan had an endless demonic aura to sustain the Demon Realm. If he was not able to use his devastating power to destroy the Flame Demon Emperor in a short period of time, the Flame Demon Emperor would be almost invincible.

We just have the power of destruction. Kel'thugad looked up and glanced faintly at the endless flames. The Flame Demon Emperor, who seemed incomparably strong, showed a penetrating smile.

Although the Molten Flame Realm of the Fire Demon Emperor has the advantage of super endurance. However, the Fire Demon Emperor's use of it was obviously not as delicate as the use of the Demon Realm.

For example, Illidan almost merged with the demonic realm after reaching the mythical level. If he opens the Demon Realm, then Illidan can appear in any corner of the realm at any time and attack the enemy from an impossible angle.

But the Flame Demon Emperor can't. What it can do is to summon a small flame demon with no time limit in the Molten Fire Realm with almost infinite energy, that is, to form a huge energy body that cannot be destroyed to fight.

The Fire Demon Emperor was surrounded by four Hellfires and four Death Knights who were walking through the air. It was extremely disgusted by the feeling of the Lich's frost nova striking the Fire Demon Emperor, and the cold feeling that seeped into its energy body and spread into its body was the most disgusting thing for a flame creature like it.

But neither Hellfire nor the Death Knight are easy to match. Whether it's the Flame of Hellfire's sacrifice, or the Necromantic Energy and Death Coil attached to each of the Death Knight's hits, they can all deal some damage to the Flame Emperor.

As a result, it can only deal with these eight guys, unable to break through their siege and find trouble with the Lich. At most, it is to manipulate the flame energy in the Molten Realm to scorch the lichs, but under the protection of the uninterrupted frost armor around those lichs, these flames can only return to nothing.

All the Fire Demon Emperor could count on was that the Hellfires that were apparently summoned would disappear after the summoning time limit had expired. In that case, four Death Knights alone would not be able to trap it. When the time comes, the Emperor of the Flame Demon will be able to go to trouble those hateful lichs.

However, all of a sudden, the Fire Demon Emperor felt that something was wrong. Well? That extremely nasty ice attribute attack hasn't appeared for a while, huh?

The Fire Demon Emperor was alert. The Frost Nova cast by the Lich is the primary way the undead hero weakens it, and there's no reason to stop it. As for the energy (mana) of those lichs being depleted, the Fire Demon Emperor wouldn't believe it.

It had really thought before that those ice attacks that were obviously spell-like would consume energy. And with the entire lava country as its backing, it will not be afraid of energy competition.

But the lich's energy seemed endless. Obviously, in its senses, after suffering a few rounds of ice attribute attacks, those lichs should no longer have the energy to cast spells in their bodies, but after they each "digested" a beetle in a wonderful way, they became vigorous again.

There is a conspiracy! Everything in the Molten Fire Realm can be easily sensed by the Flame Demon Emperor. After turning his attention to the eight lichs who had stopped casting the Frost Nova, the Firelord was horrified.

The eight lichs led by Kel'thugad were surging with extremely large and obscure energy. From this, the Flame Demon Emperor felt a complete aura of death. This aura of death gives it a feeling that is even more uncomfortable than the death entanglement of the Death Knight.

Before the Emperor of Fire could make a move, the eight lichs had already unleashed their ultimate, and death withered.

Originally, Withering Death didn't require preparation time, and as a natural ability, the Lich wanted to cast this ultimate skill as easily as casting Frost Nova, which could be activated at the stroke of the mind. In this way, it will not be noticed by the Fire Demon Emperor.

However, Kel'thugad knew that such a hastily launched death withering would not be able to deal a fatal blow to the Flame Demon Emperor, a mythical supreme powerhouse.

With the exception of Kel'thugad, the other clone lichs are only at level seven. And the Fire Demon Emperor is a hero equivalent to level ten. With such a large level gap, if the Lich Death Withers were cast separately, the Fire Demon Emperor's resistance would be enough to withstand such an attack.

Thus, under the auspices of Kel'thugad, the eight lichs united the forces of force. They are of the same root and origin, and they are easily combined by the creation of the altar, and a multiple death wither appears.

The Flame Demon Emperor suddenly found that there were countless purple-black rays of light around him. These rays of light flickered in a huge area, making them extremely brilliant. However, the Flame Demon Emperor didn't have the heart to look at this beautiful scene, because from these purple-black rays, it sensed a mortal danger. (To be continued......)
