The Most Powerful System

The Demon King's Cave, located in the heart of hell, is a cave, lair, and rock area with a diameter of several kilometers.

The terrain here is steep, with three natural moats.

Three moats surround the most central temple of the devil, which is where Mephisto is at the moment.

Those moats present a cliff structure, and are connected to each other by iron chain bridges. Between each sky moat is a wide abyss of thousands of feet. In a place like hell, the abyss is naturally not water, but hot molten lava ocean! If it accidentally falls, it will be submerged and melted into blood in an instant.

And near each of the moats, there are a large number of demons stationed, and from the first line of defense to the third line of defense, the further back, the stronger the strength of the demons stationed!

Even the four great demon generals, none of them dared to say that they could defeat this second line of defense.

But now, those four humans have all reached the second line of defense in the Devil's Temple?

This... is simply unbelievable!

It's no wonder that Mephisto, who has always been calm and calm with his eyes closed, opened his eyes when he heard the news, and a trace of surprise flashed across his vicissitudes old face.

"Master Demon King." The old demon servant next to the throne said respectfully when he saw the hell lord wake up.

The four great demon generals and dozens of high-ranking demons below also bowed their heads in a very respectful posture.

"Is the powerful mage you mentioned just now a bald woman?"

Mephisto's hoarse voice asked, not angry, but arrogant. Suddenly, there seemed to be an eerie atmosphere that permeated the entire Demon King's Temple. This is the terror of the Lord of Hell!

The demon spy's kneeling posture became even lower, because he was afraid of the hell ruler on the opposite throne from the bottom of his heart, and immediately replied tremblingly: "Qi...Qi Lord Demon King, that human mage is a man .”

"Oh?"

Mephisto frowned.

As far as he knows, the most powerful sorcerer in the world, and the only one he fears, is a female supreme sorcerer named Gu Yi.

Although the ancient one's magic body is weaker than him, Naihe controls all kinds of ancient and mysterious magic secrets and methods, and Kama Taj also has many amazing magic holy artifacts, which makes him feel The main reason why they are afraid and dare not rashly invade the human world under the protection of the Ancient One mage.

And since the mage who broke into the devil's cave in the heart of hell is now a man, it naturally means that the other party is not Gu Yi.

However, if the other party is not Gu Yi, who is it?

It made him curious.

The four hell generals on the four seats below couldn't help but breathe a sigh of relief when they heard the news and deduced that the human mage was not Gu Yi. They knew very well that even if their four quasi-devil king-level demon generals joined forces, they would not be the opponent of the supreme mage.

Of course, apart from the supreme mage Gu Yi, they have never heard of any powerful mage guardians in the human world.

"Your Majesty the Demon King, please allow us to meet the four humans outside for a while!"

These four quasi-devil king-level demon generals are wind, thunder, water, and fire attributes. They each hold the most powerful wind, thunder, water, and fire magic power in this hell dimension, and they use four powerful demon bodies with different attributes to prove the horror level. layers of life.

In the entire hell dimension, except for the hell lord Mephisto, it is the four of them who occupy the position of top combat power! Absolutely under one demon king, above ten thousand demons!

"Also!"

Mephisto thought about it for a while, then nodded and agreed to the four generals to make a move. He waved his hands full of sharp nails, and said in a hoarse voice, "You guys go."

After all, he himself is the majestic king of all demons, the absolute ruler of this hell world, so naturally he shouldn't take action casually. Do you want to force the Dimensional Demon God? Even in the case of such a powerful enemy invasion, the generals under his command should take the initiative to solve it first. Unless even their four great demon generals can't stand it anymore, then he will really appear on the stage.

"Obey, my subordinates will definitely kill those four humans! Take your souls and come here to worship His Majesty the Demon King!"

The four demon generals of wind, thunder, water and fire bowed their heads in unison, then got up, moved the huge demon body more than ten meters high, and stepped towards the door of the temple with murderous aura...

On the other side, in the heart of hell, Qi Yu's four masters and servants are almost breaking the second line of defense.

The second line of defense outside the Demon King's Temple is full of several high-level demons, dozens of medium-level demons, and hundreds of low-level demons. It also has a natural geographical advantage, making it easy to defend and difficult to attack. . In addition, there is a powerful and strange magic defense array. Not to mention those high-level demons, even if a quasi-devil-level demon comes, it is very likely that it will never return!

Unless the four quasi-devil king-level demon generals join forces to fight together, they will be able to break through this line of defense, but it will be relatively reluctant.

However, when the four great demon generals rushed here with their huge demon bodies, they suddenly discovered that the defense line here had fallen, and all the demon guards were wiped out. With a corpse of a demon.

Moreover, their souls were also collectively evacuated!

It is true that the souls floating out of those demon corpses were actually swallowed and absorbed by Doctor Doom.

And Doctor Doom's magical aura, after devouring those undead demons, also strengthened again! If it was said that when he entered the Demon King's Cave, he was still at the young stage of the horror-level peak, then it can be said that he has reached the mature stage of the horror-level peak!

"My God..."

Looking at the lifeless corpses of demons scattered all over the ground, the four major demon generals of wind, thunder, water and fire couldn't help but widen their eyes, and their faces were full of horror.

Even the second line of defense, which would be a headache when the four quasi-demon kings of hell joined forces, was completely defeated by the four humans in front of them in such a short period of time?

Even, none of the four humans seemed to be injured!

This... is simply unbelievable!

However, what the four great demon generals didn't know was that the current situation was actually formed when Qi Yu, a really powerful character, did not make a move, and only three servants of the terrifying level made a move.

Otherwise, if Qi Yu also joins the battle, tsk tsk, I'm afraid it only takes a snap of the fingers, and the second line of defense will completely collapse.

"Ok?"

Seeing four more demons approaching from the opposite side, and each of them seemed to be more than ten meters tall and huge in size, it was obvious at a glance that they were not ordinary demons, Qi Yu couldn't help frowning slightly.

With the help of the strongest system evaluation function, he scans and explores the past with a lack of interest.

It was suddenly discovered that all these huge and ferocious demons that arrived were all terrifying life forms!

"Hmph, finally here are some decent opponents."

Qi Yu raised the corner of his mouth, smiled slightly, and said in his heart, "Forty thousand experience points are delivered to your door."
