Mephisto, the Lord of Hell, was at the forefront, followed by dozens of hideous demons of different shapes.

All the demons in this demon king temple are all first-class powerhouses in this hell world, and dozens of powerful high-level demons work together, even the old demon king Mephisto under normal conditions will feel a lot of headaches.

Bringing them over should not be enough to turn the tide of the battle, but it is more or less a force to be reckoned with.

At the same time, the three servants under Qi Yu were attacking the third line of defense in the Demon King Cave area. As long as you break through this line of defense and go deeper, it will be the Demon King's Temple, which is also the place where the Hell Lord Mephisto is.

As the master, Qi Yu naturally didn't make a move because he wanted to maintain his compulsion and mystery, but just let the three servants under his command let go of their hands and feet to kill, and these three servants were more powerful than one another, and it didn't take long for the third line of defense, which was stronger and more difficult than the first two lines of defense, and half of it had been successfully swept away by them.

There were almost ten high-level demons, dozens of medium-level demons, and more than two hundred low-level demons reduced to dead corpses!

A large number of revenants floated in the sky above.

However, due to the fierce battle between the two sides, Doctor Doom couldn't take a break to use the magic and secret techniques on the "Hell Covenant" for the time being, so none of these souls were devoured and refined by him at present.

However, I believe that according to the current development of the situation, it will take less than a minute at most, and this third line of defense will completely collapse.

However, just as the two sides were starting to enter the second half of the battle!

Suddenly, in the gray sky not far away, hula flapped its wings, and a large group of demons were flying towards it.

And on the ground below, there is also a group of tall demons, who are rushing towards this direction with heavy and powerful steps. As they stepped on, the ground under their feet was faintly trembling!

Obviously, it's another powerful demon army!

When this demon reinforcement army arrived, the four Qi Yu masters and servants and the demons who were fighting all stopped fighting for a while, and they all cast curious glances over there. They all know that it is definitely not a simple character who can make such a big movement even when walking!

When they were close enough, their appearance and form clearly came into view.

The first to be excited was the group of demon guards of the Third Heavenly Trench Defense, who were in a bitter battle.

"Hahaha, it's the Demon King here!"

"Boom, the hell lord is here, these human powerhouses will definitely die!"

"Even Lord Mephisto, the master of our Hell Dimension, has personally descended, it seems that these humans are indeed difficult to deal with!"

"However, to be able to die at the hands of the dignified Hell Lord, these guys can be regarded as worthy of death!"

These demon guards, not to mention how excited they are at the moment.

On the side of Qi Yu and the others, Hatred and Magneto, they had never seen Mephisto before, and they had no impression of his image. I thought that it was just a group of relatively powerful demons who came to support, but now that I heard those demon guards say this, I immediately learned that among this group of demons, even Mephisto, the master of the Hell Dimension, has come!

Although they had never seen Mephisto before, the two of them knew which of these demons on the other side was the Lord of Hell.

Very recognizable!

Because these dozens of demons who rushed here all have huge sizes, generally ranging from two meters to ten meters, or have wings on their backs, or have hands and feet similar to insects or beasts, or have horns and tails, in short, each one is more terrifying than the other!

In contrast, at the very front of those huge demons stood a small, gray-haired old man.

Although the old man's face looked vicissitudes, invisibly, it gave people a sense of not being angry and arrogant, as well as mysterious and extremely unsettling!

"It seems that the old man should be Mephisto."

Magneto speculated, and both he and Abomination turned their heads slightly to look at their masters beside them for confirmation.

Qi Yu nodded.

"Although he looks like a thin old man who seems to be weak, in fact, even the huge high-level demons behind him are not necessarily his opponents."

Qi Yu said lightly.

In fact, from the very beginning, when Mephisto arrived here, Qi Yu used the evaluation function of the strongest system to scan and probe the other party, and found that the life level of this old demon king was terrifying, and it belonged to the peak of the terrifying level.

There is only a line away from the quasi-overlord level!

Moreover, Mephisto's current form seems to be just the norm, and in his body, there is also a very tyrannical and extremely surging magic power, and it has even reached the overlord level! It's just that the assessment of this life level, currently in Qi Yu's virtual vision, it is a gray frozen state. It is estimated that only when Mephisto breaks the seal and sacrifices his true body, the life level status bar will be activated.

And at this moment, among the four masters and servants, there is only one Doctor Doom, and his expression does not look very good.

Doctor Doom gritted his teeth, his silver-glowing face filled with resentment. The dark green magician special effect flames floating up and down his body also burned more intensely!

It was as if at the moment when I saw the enemy who killed my mother, and my emotions became excited!

"Mephisto, do you remember me?" Doctor Doom stared straight at the other man, as if two flames were burning in those eyes.

"Huh?"

Seeing that someone on the human side was talking to him, Mephisto frowned curiously, and when he frowned, the vicissitudes of life rolled up in folds.

To be honest, no matter at first glance or on closer inspection, he couldn't make out what the human mage on the other side, wearing a dark green mage robe and a silver complexion, had any relationship or past intersection with him.

However, he could clearly perceive the anger in the other party's eyes at the moment, as if the other party had an indelible hatred with him!

It's just that, no matter how much he recalls, Mephisto doesn't have the slightest impression of destroying the doctoral students. Even the apprentices under the command of the Ancient One Supreme Master of the Human Kama Taj Mage Group, he had some impressions, but he just couldn't remember who this mage in front of him was.

"This mage, this Demon King, has never seen you."

Mephistopheles' hoarse, eerie voice was muffled.

"The way I look now, you naturally can't tell the difference."

Doctor Doom smiled, a hint of anger in his smile, "Because when you first saw me, I was just a child!" ”
