The devil's cave, located in the heart of hell, is a cave, nest and mountain rock area with a diameter of several kilometers.

The terrain here is steep, with three natural grabens.

Three natural grabens surround the most central demon king temple, which is where Mephisto is now.

Those natural grabens show cliff structure, which are connected by iron chain bridges. Between each natural graben, there is a wide abyss. In places like hell, the abyss is not water, but a hot molten sea! If it falls down carelessly, it will be submerged and melted into blood in an instant.

A large number of demons are stationed near each natural graben, and from the first natural graben defense line to the third natural graben defense line, the more backward, the stronger the strength of the demons stationed!

Even the four magic generals dare not say that they can break the second natural moat defense line.

But now, those four humans have all hit the second line of defense of the demon king's temple?

This... Is incredible!

It is no wonder that Mephisto, who has always been calm and calm, closed his eyes and rested, also opened his eyes when he heard the news, and a trace of surprise flashed on his old face.

"Devil... Lord devil." the old devil servant next to the throne said respectfully when he saw the Lord of hell waking up.

The four great demons and dozens of higher demons at the bottom all bow down and show great respect.

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

Mephisto asked in a hoarse voice, not angry, but self threatening. Suddenly, it seemed that there was a gloomy and terrible atmosphere in the whole demon king temple. This is the horror of the Lord of hell!

The devil scout knelt lower, because he was afraid of the hell master on the opposite throne from his heart. He immediately replied with a trembling reply: "Qi... Tell the Lord of the devil that the Human Mage is a man."

"Oh?"

Mephisto frowned.

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

Although the magic body of naguyi is weaker than him, he still controls all kinds of ancient and mysterious magic mysteries and means. Moreover, there are many powerful magic holy vessels in Kamata Taj, which is the main reason why he feels afraid and dare not rashly invade the human world under the protection of guru Guyi.

Now that the mage who broke into the heart of hell demon king cave is male, it naturally means that the other party is not Gu Yi.

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

It made him curious.

After hearing the news, the four demons of hell on the four seats below inferred that the Human Mage was not ancient, and they couldn't help but breathe a sigh of relief. They knew very well that even if their four quasi demon generals joined hands, they would not be the opponent of the supreme mage.

Of course, except for the supreme mage Gu Yi, they have not heard of any powerful mage guardian in the human world.

"Lord devil, please allow us to meet the four humans outside for a while!"

These four quasi devil level magic generals are wind, thunder, water and fire attributes. They each master the most powerful wind, thunder, water and fire magic in the dimension of hell, and demonstrate the terror level life level with four powerful magic bodies with different attributes.

In the whole hell dimension, in addition to the hell Lord Mephisto, the four of them occupy the position of top combat power! Under the absolute demon king, above all demons!

"Good!"

After a little consideration, Mephisto nodded and allowed the four demons to make a move. He put his hands full of sharp nails and said faintly in a hoarse voice, "go."

After all, he is the king of demons, the absolute master of the hell world. Naturally, he shouldn't shoot casually. Do you want the force of the dimension demon God? Even in the case of such a strong enemy invasion, it should first be the senior general under his command to solve it. Unless even their four demons can't stand it, he will really play then.

"Yes, my subordinates will wipe out the four humans! Take your souls and come to worship your Excellency the demon king!"

The four demons of wind, thunder, water and fire bowed their heads in unison, then got up, moved the huge demon body up to more than ten meters, and stepped quickly to the murderous boiling outside the temple door

On the other side, in the heart of hell, Qi Yu's master and servant almost broke through the second natural moat line.

The second natural moat defense line outside the demon king's temple is fully stationed with several high demons, dozens of medium demons and hundreds of low-level demon minions, as well as natural terrain advantages, which are easy to defend and difficult to attack. In addition, there is a powerful and strange magic defense array. Not to mention those higher demons, even if a quasi demon comes, it is very likely that it will never return!

Unless the four quasi demon generals work together, they can break through this line of defense, but they will be reluctant.

However, when the four demons arrived here with huge devil bodies, they suddenly found that the defense line here had fallen, all the devil guards were destroyed, and the devil bodies were scattered all over the pothole broken grain rock ground.

And their souls were collectively evacuated!

Indeed, the souls floating from the devil's body were actually swallowed and absorbed by Dr. destruction.

The magic smell of Dr. destruction has been enhanced again after swallowing the demons and undead! If you were still at the level of terror level peak childhood when you first entered the demon king cave, you can say that you have reached the level of terror level peak maturity now!

"My God..."

Looking at the dead bodies of many demons scattered all over the ground, the four magic generals of wind, thunder, water and fire couldn't help staring at each other, and their faces were full of horror.

Even their four hell quasi demons would have a headache under the joint efforts of the second line of defense. As a result, they were completely defeated by the four humans in front of them in such a short time?

Even, none of the four humans seems to be hurt!

This... Is incredible!

However, what they didn't know was that the current situation was formed when Qi Yu, a really powerful character, didn't make a move, and only three terror level servants made a move.

Otherwise, if Qi Yu joined the war, tut Tut, I'm afraid it would only take one finger to snap, and the second natural graben defense line would collapse completely.

"Huh?"

Seeing four more demons coming from the opposite side, each of them looked more than ten meters high and huge. At a glance, Qi Yu knew that they were not ordinary demons. Qi Yu couldn't help frowning slightly.

With the help of the strongest systematic evaluation function, he scanned the past without interest.

Surprisingly, these new huge ferocious demons are all terrorist creatures!

"Hum, finally there are some decent opponents."

Qi Yu raised his mouth, smiled and said in his heart, "40000 experience points have been sent to the door."
