In the underworld space, two scorching blood-colored flames burned violently, and in the flames, dozens of soul shadows writhed violently, struggling, and in a moment, they collapsed.

Among them, a soul shadow was particularly powerful, and it was obviously a king-level soul body. This is a king sent by the City of Original Sin to garrison this place, but at this time, he is besieged and killed by Dugu and Nalan.

"So you're the two people the city is looking for. I have sent a message to the lord of the city, and in a moment the lord will be here, and then you will all die. The shadow of the soul struggling in the karmic fire threatened:

Dugu Nalan was unmoved, and the blood-colored flames were even worse, burning so that the soul shadow screamed miserably. Dugu's main attack, with the Nine Heavens Thunder attached to the spear, attacked and killed the soul shadow. Nalan is on the periphery of the karmic fire, resisting the soldiers who keep coming to the underworld.

Finally, the king-level powerhouse collapsed under the fierce burning of Dugu's karmic fire, and turned into a massive amount of soul power.

Dugu stripped the memory of this king-level powerhouse, and left his soul power to Nalan. After all, Nalan's soul power has not yet reached the king realm, and the soul of this king realm has little effect on Dugu.

Dugu looked at it for a moment, and his face became more and more gloomy. Sure enough, as he expected, there was another door in the Thunder Sea, which was the door of the lead.

The ghosts under the cave have endured for a long time, and it is precisely because of the obstruction of this thunder sea that they dare not approach.

"Damn, these bastards of the underworld want to permanently penetrate the gate of the underworld and reach the human world. If it weren't for the Nine Heavens Thunder Divine Spear guarding the cave for 10,000 years, I'm afraid they would have attacked the world long ago. Dugu scolded:

"What do we do now?" asked Nalan.

Dugu's eyes rolled slightly, and suddenly his eyes lit up. Isn't this person from the underworld who wants to go to the world when he opens the door of the underworld, maybe he can take this opportunity. Let's return to the world. Dugu's eyes are getting brighter and brighter.

"Into the Thunder Sea!" Dugu said solemnly:

"You're crazy, even if you have the way of thunder. But this thunder sea is not something you can fight against, if you are not careful, we may be wiped out at any time. Nalan stared at a pair of eyes and exclaimed:

"I don't have any other choice, maybe this is the only chance we can get back into the world. I don't want to miss it. Dugu looked at Nalan solemnly.

"Crazy!" Nalan pouted, but he was undoubtedly a little moved. has been away from the world for thousands of years, and I don't know what the world is like today. He looked into the depths of the Thunder Sea with some fascination.

At this moment, the voice of the old dragon came from inside the brute dragon spear.

"Finally found it!" In the Broken Sword Space, the old dragon looked at the Lei Hai in front of him with a complicated expression.

"What are you talking about? What are you looking for? Dugu looked at the spear with some confusion.

"There is something I need in this thunder sea, and there is one thing that is perfect for you. Why do you think I took you to the underworld in the first place, and when the gate of the underworld opened, I sensed the existence of these two things. But because this sea of thunder concealed the aura, I couldn't determine their direction. Now that I am close to this thunder sea, I know that it is in the depths of this thunder sea. The old dragon said with a complicated expression:

Dugu's heart shook, this thing must be extraordinary if this old dragon can care so much.

"Nalan, you haven't mastered the way of thunder, this thunder and lightning will hurt you a lot, you better go into the sword breaking space first! Dugu says:

Nalan nodded, his life was saved by Dugu. He had already given his life to Dugu, and at this time, he turned into a ray of light and sank into the spear without the slightest hesitation.

"Dugu boy, your way of thunder has just begun, although this envoy's thunder level is good. But the level of the thunder that killed the Thunder Sea was no worse than your Nine Heavens Thunder. The old dragon's voice sounded in Dugu's heart.

"So what should I do? Dugu frowned and said:

"I'll help you, but those two things in the sea must be retrieved for me. "The old dragon is very determined.

Since he met Lao Long, Dugu has never seen Lao Long so solemn. It seems that at the expense of the universe and the destruction, the mountains and rivers are reversed to get these two things. Dugu is more and more concerned about the things in the thunder sea.

The endless sea of killing thunder, blood-colored thunder filled the air, covering the entire void.

Dugu walked through this boundless sea of thunder. Thousands of thunderbolts slashed down and fell on him. However, he was only slightly stunned, but there was no major problem.

This brute dragon sword is really a good thing, and it turned into a protective white armor to wrap Dugu in it. No matter how violent the thunder outside was, they were all blocked by this armor.

Dugu was secretly glad that if it weren't for this brute dragon sword, I am afraid that he would have been split into ashes when he was still surrounded by thunder. It turns out that he really underestimated this thunder sea.

This blood-colored divine thunder is more crazy and tyrannical than the Nine Heavens Thunder.

The closer he got inside, the more violent the thunder became, and gradually Dugu's figure began to shake. Although this armor blocked the thunder, the strong vibration on the armor was unavoidable. Dugu grinned, and only after walking a little far, the thunder became furious like this, and half of his body was numb.

"Hiss!" A serpentine thunderbolt slammed into Dugu's armor, instantly shaking him dizzy and constantly retreating.

"I'll go! What the hell, this thunder turned into a little snake. Dugu exclaimed.

"Hey, this thunder is a bit extraordinary, how can he know such a profound method and evolve the Great Dao of Heaven and Earth with his body. The old dragon said in amazement:

When Dugu heard this, he was immediately shocked, these thunderbolts could not have become fine.

A blood-colored giant bear waved its big claws and slammed into Dugu, and Dugu was knocked into the air when he was isolated.

"Shit! What kind of damn thunder is this, so powerful. Dugu spewed out a breath of soul and scolded and said:

After all, there are few thunderbolts that can transform into animals, and Dugu has only encountered seven such thunderbolts along the way. The rest of the thunder was kept out alive by this armor. But even if he only encountered seven such thunderbolts, it would still shock his soul power and numb all over his body.

That's when it happened. Dugu faintly heard the sound of weapons clashing.

"Strange, how can there be people here?Who is so bold to dare to fight in the depths of this killing thunder pool?" Dugu slowly approached the source of the sound.

"Roar!" the roars of the beasts rang out one after another. The scene in front of him couldn't help but tremble violently and his scalp tingle.

I saw that in the distant thunder sea, tens of thousands of thunder beasts roared and surrounded the five figures.

Any of these five figures is extremely powerful. These tens of thousands of thunder beasts couldn't help the other party for a while.

"The Emperor Realm turned out to be a powerhouse in the Emperor Realm. Dugu looked at the five figures in the distance in shock. The heavy pressure coming from his thin body made him sure. The other party must be a strong man in the imperial realm.

Suddenly, Dugu saw a familiar figure: "Original Sin City Lord?"

In the Broken Sword Space, Nalan heard that it was the City Lord of Original Sin, and his eyes were full of hatred. The Lord of the City of Original Sin imprisoned him like a slave for ten thousand years. He had already sworn to kill the Lord of the City of Original Sin. But I met it today.

"They are not affected by this thunder sea?" Dugu saw the clue. Each of the five people was wearing a black light armor, and the thunder slashed in front of them and turned around strangely, never really slashing at them.

"What kind of armor is that? It's so strange that the thunder can't even touch their bodies. "Look at your armor again. Although the material is unparalleled, the thunder cannot slash at him, but he is always injured by the power of the shock.

"Boy, what kind of eyes do you have? The old dragon raised his eyebrows, as if he was very dissatisfied with Dugu's eyes.

"I've been shocked to death for half a day, but people's armor can't even cut thunder. Does this still need to be distinguished?" Dugu pursed his lips and said in his heart:

"Ahh I don't know the goods. It's called a lightning armor, and it can indeed avoid the attack of thunder, but its own material is very fragile. You don't notice that those people are tied up. Don't you dare to attack violently? Otherwise, these thunderbolts would have been destroyed by them long ago. The old dragon scolded and said:

Only then did Dugu find that the range of movements of those people was controlled within a small range, and even their eyes glanced at the armor on their bodies from time to time, as if they were worried that they would suddenly shatter.

"So that's the case!" Dugu pinched his chin and said with a wicked smile:

"Boy, what are you doing with bad intentions?" asked the old dragon.

"I was thinking if I went up up and sneaked into them. What will happen to them?" Dugu's face was full of ill intentions.

"I agree!" Nalan changed his gloomy face and immediately expressed his position.

Even the old dragon was bright, and a wicked smile faintly appeared on his face.

Dugu secretly detoured behind the original sin city lord and quietly waited for the opportunity.

"Damn, if it weren't for the fragile material of this lightning armor, Lao Tzu really wanted to kill all these beasts. The original sin city lord's face was full of unhappiness, and he shouted angrily:

"Original sin, don't be distracted, the five of us can barely deal with this thunder when we join forces, if the distraction causes the armor to shatter, we can only retreat helplessly. A black figure spoke:

"I know! Hmph!" The City Lord of Original Sin snorted coldly. Among the five, he is the weakest, and he is usually suppressed by the other four, and he has long had enough of that anger.

At this moment, in the depths of the Thunder Sea, a hundred-zhang long dragon composed of thunder shot towards the City Lord of Original Sin.

"Oops! It's Zure's doppelganger. "The City Lord of Original Sin shouted, the secret way is not good. But the blood-colored thunder dragon had already whipped him upside down with its tail.

"Good opportunity!" Du set off in isolation, shooting towards the original sin city lord like a bolt of lightning, and the white armor slammed into the original sin city lord's vest.

"Click!" a crack cracked in the lightning armor on the original sin city lord's body. This clicking sound shook the figure.

"It's not broken yet!" Dugu shouted angrily and kicked the vest of the City Lord of Original Sin. Immediately, he flew upside down towards the thunderous dragon.

"Boy, you should die!" the resentful voice of the City Lord of Original Sin resounded through the sea of thunder.
