After dealing with the insects in front of them, Duan Chen and the others walked directly into the mine, and at this moment, in the mine, after missing these bugs, it was much quieter, and the wind mania also continued to send out dispersal magic one by one against the black fog in front of them, opening the road in front of them.

"The black fog here is particularly thick, I suspect that this is the source of the black fog!" Looking at everyone, Feng Mania said loudly, the black fog in front of him was getting thicker and thicker, and he was a little overwhelmed, which made Feng Mania a little unbelievable. You know, Wind Madness's skill is not an ordinary skill, but this skill can dispel darkness.

"Looks like there's some demon treasure here!" Seeing this scene, Duan Chen said loudly, apart from this explanation, there is no other explanation at all, and only the heavy treasure of the demon clan, or the suppression of the demon king, etc., can have such a terrifying demonic qi.

"It's weird!" Hearing this, Feng Mad also nodded and said.

"There's a door there!" Suddenly, the octopus said loudly, and everyone also saw in the distance, there was indeed a small door there, and the continuous eruption of demonic energy was overflowing from the crack in the door.

"What the hell is this! What a heavy demonic energy! Everyone looked at the stone gate in front of them with some solemnity, and said loudly, in the crack of the stone door, there were continuous bursts of black gas, and these black gases were enough to make everyone feel frightened, and it could be seen that this stone gate was strange.

"Let's go inside!" Blood splattered Qianli said loudly, and then, he directly pushed open the stone door in front of him.

"Boom!" When the blood splashed thousands of miles to push open the stone gate, an explosion suddenly resounded, and also pushed everyone away from the distance, at this moment, everyone looked at the stone gate with some surprise.

"Demon King Bead!" Duan Chen's eyes narrowed slightly, looked at the substance inside the stone gate, and said aloud.

"Demon King Beads?" Hearing this, everyone suddenly showed a look of surprise, and also looked at the black beads in the stone gate, at this moment, the black beads continued to overflow with black demonic energy, and this demonic energy was emitted from the entire black bead, and everyone could feel the demonic energy in the black beads.

"This is the legendary Demon King Bead?" Looking at the Demon King Bead in front of them, everyone's eyes were full of surprise.

"This thing is the Demon King Bead!" Duan Chen looked at the Demon King Bead in front of him, and said: "The best thing about the Demon King Bead is that it can catalyze the forbidden spell cannonballs of the dark attribute, as long as they are installed in the Demon Soul Cannon, they can make the Demon Soul Cannon automatically produce many shells of the Demon Soul Cannon of the dark attribute, and the power of such cannonballs is extremely huge."

"Roar!" At this moment, the black mist violently erupted with a dazzling color, and then, under the gaze of everyone, the black qi in front of him exploded directly, and in an instant, it rushed towards Duan Chen and the others. Turned into a huge black monster, and when they saw this monster, everyone took a step back, nervously staring at the monster form formed by the black qi.

The monster in front of him, all black, and the black monster in front of him suddenly burst out with a roar, and rushed directly towards Duan Chen and the others.

"Dark Demon King: One hundred and thirty level monarch monsters, with 550,000 HP! Condensed by the demonic energy emitted by the Demon King Bead, the terrifying strength is extremely domineering! Looking at the introduction of the Dark Demon King, everyone looked at the dark monster in front of them, the monster in front of them, the body was strong, especially the thing in his hand, it was even more huge, like a pillar, which was daunting.

At this moment, the Dark Demon King in front of him let out a violent roar, and then, as soon as his body swung, he rushed towards Duan Chen and the others, and in the hands of the Dark Demon King, the pillar-like weapon was aimed at Duan Chen and the others and smashed them fiercely.

"Get out!" The blood splashed thousands of miles forward, and the heavy shield directly resisted in front of him, directly blocking the powerful blow of the Dark Demon King, and then, the heavy axe of the blood splash thousands of miles slashed fiercely, splitting the Dark Demon King back a few steps in an instant.

"Roar!" A furious roar sounded, and immediately, the Demon Dragon and the Ice Burst Bear rushed up directly, and as soon as the two bosses with outstanding physical bodies appeared, they began to attack the Dark Demon King.

"Boom!" The Dark Demon King held a huge pillar like a telephone pole in his hand and threw it fiercely, and in an instant, it hit the Ice Explosion Bear that rushed up first, and under the powerful blow of the Dark Demon King, the Ice Explosion Bear was like a ball that was knocked away, and it was thrown out fiercely.

"This guy's attack power is not simple!" Duan Chen looked at this scene and said loudly, the Dark Demon King's attack is strong, even if he doesn't dare to say that he can catch it, you can imagine how difficult this guy is.

"I'm coming!" Dream Weaving shouted, and the longbow in his hand was raised directly, and then, with the Dark Demon King is arrow, under the violent explosion, the Dark Demon King's body was directly knocked out. Yumori's attack power,Extreme domineering,Even the monarch boss is difficult to resist.。

"Magic Knife Technique!" Duan Chen rushed forward at this moment, the battle knife in his hand directly turned into a touch of black, and the magic knife technique was launched in an instant, bombarding the Dark Demon King's body, and sending the Dark Demon King with a damage value of nearly more than 80,000 points.

"Roar!" The Dark Demon King roared wildly, and the huge pillar in his hand waved directly, and with the Dark Demon King's waving, Duan Chen and the others were immediately knocked out by this huge earth pillar, at this moment, the Dark Demon King continued to attack everyone, the pillar smashed people underground, and the attack that erupted was also huge, and Duan Chen and the others were difficult to resist at all.

"This thing is crazy!" Heartbroken Wuchen said out loud, the effect of this thing is extremely obvious, the power of that blow can definitely open the mountain and crack the rock, especially the huge pillar in his hand, not to mention the damage he received when he was smashed, but that kind of huge force smashed on his body was enough to knock himself out.

"Boss Qianli, help me block this thing, I'll deal with this guy!" The wind shouted wildly, and then, directly withdrawing from the battle, began to prepare for the attack.

Hearing this, the blood splashed Qianli also nodded, the heavy shield in his hand suddenly clenched, and rushed over directly at the Dark Demon King in front of him, the huge shield smashed on the Dark Demon King's head, smashing the Dark Demon King back a step, at this moment, only the blood spattered Qianli could do this, after all, the defense of the tyrant's blood spattered Qianli was amazing, even if the Dark Demon King's pillar smashed on him, the blood spattered Qianli did not have much reaction.

"Roar!" Two roars rang out, and the Demon Dragon's Ice Burst Bear also erupted directly, rushing towards the Dark Demon King, and the two figures were biting towards the Dark Demon King.

The two summoned beasts and the blood spattered thousands of miles, just suppressed the Dark Demon King in front of him, and at this moment, everyone's attacks fell on the Dark Demon King's body, and the Dark Demon King let out a violent roar several times, but there was no way at all, after all, the attack power of Duan Chen and the others was too strong.

And at this moment, the wind madness is constantly chanting the magic that belongs to the light forbidden spell, and the sky has long been shrouded in a stream of white, and the light restricts the darkness, so this blow of the wind madness may be the most effective attack.

"Divine punishment!" Fiercely, the wind roared loudly, and then, a violent light power rushed out in an instant, and the light spear exploded directly, bombarding the Dark Demon King in front of him, knocking the Dark Demon King out fiercely.

"Whew!" In an instant, the Dark Demon King's terrible screams rang out.
