The Great Overlord: Simulating the Future, Dominating Speedrunning

Chapter 181 Supreme Heart Demon Seal, Lu Chen's Choice
Under the Thunder Demon Abyss,

Lu Chen and Mandala came walking in the air, their eyes looking at the bottomless dark abyss. The abyss was like a demon dragon lurking deep in the ground, winding and entwined, which was chilling.

"I never expected that there would be the inheritance of the Heart Demon Thunder Emperor here."

"Now that I think about it, perhaps this Thunder Demon Abyss isn't a naturally formed treasure land at all, but rather a wonder created after the battle between the Heart Demon Thunder Emperor and the Mysterious Demon Emperor."

Mandala looked at the bottomless Thunder Demon Abyss, and a complex look flashed in his eyes.

She sighed softly, her voice low and distant, "The Inner Demon Thunder Emperor... was also a renowned and powerful being in ancient times. Although not as powerful as the Thunder Emperor, who was ranked among the Nine Ancient Emperors, he was still one of the strongest beings below the Saint Grade Heavenly Supreme."

"If his inheritance is truly hidden in this abyss, it probably won't be easily accessible to anyone."

Lu Chen nodded slightly and said in a deep voice: "According to the previous investigation of the white-robed clone, there is at least one peerless holy object in that inheritance place. As for whether there are other means, I don't know."

"But so much time has passed. Even if there are other means, it would be difficult to stop us."

Mandala glanced at Lu Chen sideways, a faint smile on her lips: "You are quite confident. Aren't you afraid that there are traps set by the evil tribes outside the domain, waiting for you to jump in?"

Lu Chen smiled, stroked the stone cup at his waist, and said nothing.

The clone had already found out before that the space did not have the ability to isolate communications. With the life-saving item given by Senior Yan Di, he could still take the risk.

After all, it is a peerless holy object. If you can get it, it will be enough to greatly increase your strength in a short period of time.

……

Boom.

Low rumbling thunder continued to come from the depths of the darkness. Lu Chen and the other person turned into light and shadow and shuttled down. In just a dozen breaths, they had penetrated thousands of feet underground and arrived at the depths of the sea of ​​thunder.

Deep in the sea of ​​thunder,

Lu Chen and Mandala stood in the air, looking at a dark vacuum area not far away, both with solemn expressions.

hum!
Lu Chen waved his hand, and a crystal-like sword emerged and was held in his hand.

Immediately, he swung his sword, and the brilliant sword energy cut through the void. The surrounding space made a crisp cracking sound as if it could not bear the heavy burden, and a space crack of dozens of feet in size suddenly spread out.

"I'll go in first, and Junior Sister will follow me."

Lu Chen held the Heavenly Emperor Sword in his hand, gave an instruction, and took the lead to step in.

Mandala nodded slightly, flipped her little hand, and a brilliant golden light flashed, and a dark pyramid was suspended above her palm.

Intermediate holy object, the Starry Sky Demon-Suppressing Tower!

Holding the Starry Sky Demon-Suppressing Tower, Mandala also walked into the space crack.

……

within space,

On the blood-red earth, countless thick thunders shuttled through it, like countless pitch-black pythons, crawling in twists and turns on the entire earth.

The sky was covered with dark clouds, and countless thick thunders were flying through the clouds, making deafening roars.

Lu Chen gripped the Heavenly Emperor Sword tightly, and the sword body trembled slightly, as if sensing the violent power of thunder around him.

His eyes were solemn as he whispered to himself, "This space is filled with Netherworld Heart Demon Thunder. If a strong person with thunder-attributed skills were to cultivate here, he would probably make rapid progress."

Mandala followed closely behind, the Starry Sky Demon-Suppressing Tower in his hand emitting a faint golden light, isolating the surrounding thunder power.

She looked up at the sky, her brows furrowed slightly. "The power of thunder here seems to have spirituality, as if it is guarding against outsiders like us."

Lu Chen nodded: "It has spirituality but no intelligence. It is difficult for such a rare object to give rise to true intelligence. The more powerful it is, the more so. However, the Heart Demon Thunder Emperor uses it as a means of protection, which is a very good choice."

As soon as he finished speaking, a thick bolt of lightning suddenly struck down from the sky and headed straight for Lu Chen.

Lu Chen's eyes flashed, and he swung the Heavenly Emperor Sword horizontally. Crystal-like sword energy shot out and collided with the thunder. Amidst a loud bang, the thunder was shattered by the sword light and turned into countless tiny electric lights that scattered in all directions.

Lu Chen put away his sword and stood, looking up at the sky with a serious gaze. The shattered thunder did not completely dissipate, but instead condensed into a thundercloud in the air.

The thundercloud rose up and merged into the sky in an instant. In the huge thundercloud, faint flashes of lightning appeared, and there was a tendency for it to erupt again.

Lu Chen frowned slightly and said with some confusion: "This thunder is a bit strange. It can actually repair itself."

Mandala's expression was also slightly solemn. He said in a deep voice, "It is said that in ancient times, the Heart Demon Thunder Emperor used the Netherworld Heart Demon Thunder as a guide to create many methods. Among them was a formation called the Netherworld Thunder Cloud Formation."

"This formation is based on the Netherworld Heart Demon Thunder, and is infused with the demonic energy of the Heart Demon Clan. It can not only repair itself, but also continue to grow stronger with the help of everyone's heart demons."

"If you remain trapped in this for too long, you will unknowingly develop inner demons. If you can defeat them, that's fine. If you can't, you will be devoured by your own inner demons and become the nourishment for this formation."

"The Heart Demon Clan? One of the thirty-two major clans outside the domain?"

A look of astonishment flashed in Lu Chen's eyes, and he asked in disbelief.

Mandala nodded, her eyes complicated as she said, "Do you think the Heart Demon Thunder Emperor is some decent person? Back then, he was known as a super-ferocious demon. To become stronger, he would do anything, even daring to borrow the power of the evil tribes from outside the domain."

"If he hadn't been strong enough and had the Thunder Emperor as his guarantor, and if he hadn't killed more than a dozen Demon Emperors from the extraterritorial evil clans to clear his name, he would have been expelled from the Ancient Thunder Palace long ago."

Upon hearing this, Lu Chen's eyes flashed with a solemn expression: "He even dares to borrow the power of the Heart Demon Clan. This Heart Demon Thunder Emperor is truly audacious."

Mandala nodded, his eyes swept around, and whispered, "If my guess is correct, the reason why there is a constant flow of Netherworld Heart Demon Thunder here is because of the existence of this Netherworld Thunder Cloud Formation."

"It can not only continuously repair itself, but also grow stronger with the inner demons of outsiders. Unless we can find the center of this formation, if this continues, we will probably also develop inner demons."

Lu Chen gripped the Heavenly Emperor Sword tightly in his hand and said in a deep voice, "If that's the case, then I'll lead the way. If I'm not mistaken, the Supreme Heart Demon Seal is the core of this formation. As long as we capture it, this formation will collapse without any attack."

After saying that, Lu Chen took a step forward, and the spiritual power in his body instantly burst out, and a brilliant light appeared on the Emperor's Sword.

Immediately, he swung his sword, and the thunder that filled the surrounding sky and earth retreated. In the blink of an eye, a vacuum zone was cleared.

"go!"

Lu Chen turned into a sword light and rushed directly towards the Thunder Lake not far away, where the Supreme Heart Demon Seal was located.

Seeing this, Mandala hurried to follow.

……

After a while,

Lu Chen and Mandala finally arrived at the edge of Thunder Lake.

The lake in front of me was pitch black, formed by the purest power of thunder. The surface of the lake was shimmering, but it was not water waves, but countless tiny lightning bolts jumping and flashing, as if the entire lake was breathing.

In the center of the lake, an ancient altar stood quietly. Above it hovered a silver lightning seal, emitting a heart-pounding wave. Lu Chen's gaze was solemn, and he whispered, "That is the Supreme Heart Demon Seal... It is indeed extraordinary."

Mandala nodded, with a hint of fear in her tone: "Be careful, the thunder power in this Thunder Lake is more violent than that outside. If you are not careful, you will be swallowed by it."

Lu Chen nodded slightly, and then the spiritual power in his body surged, and the space behind him was turbulent. Faintly, a brilliant crystal body appeared behind him.

Heavenly Flame Dharmakaya!

A Sky Flame Dharma Body of hundreds of feet long enveloped Lu Chen. When he entered the Dharma Body, the Dharma Body suddenly burst out with brilliant spiritual light, and his whole body was filled with a powerful aura. He raised his hand and grabbed the Supreme Heart Demon Seal.

hum!
Sensing the coming crisis, the Supreme Heart Demon Seal on the altar trembled slightly, and also burst out with unprecedented light. The sound of splashing water was heard, and countless waves swept over from all around, suddenly condensing into a huge thunder figure!

The figure was hundreds of feet tall, wrapped in the power of thunder. Holding a thunder spear, his eyes were like lightning. Like the most loyal guard, he glared at Lu Chen and roared, "Trespassing into the forbidden area, death!"

boom!
The giant thunder shadow held the thunder spear in his hand and thrust it forward suddenly, colliding with the giant crystal hand, and countless dazzling lightning flashes burst out immediately.

At the same time, circles of invisible sound waves spread out from the point of collision. The sound waves were particularly strange. They actually penetrated the Dharma body and directly hit Lu Chen.

A look of astonishment flashed in Lu Chen's eyes. He was not careful and took a few steps back under the impact of this force. Every step he took caused the void to tremble and flames to splash.

"Interesting! Just now I was saying that this Netherworld Heart Demon Thunder couldn't possibly develop intelligence, but now a Thunder Spirit with intelligence has appeared to block the way."

"I don't know whether this was nurtured by the Inner Demon Thunder Emperor using secret techniques, or whether it was born naturally within this Netherworld Thunder Cloud Formation."

Lu Chen steadied his body and looked at the huge thunder spirit in front of him. Instead of being angry, he looked at it with curiosity and said with interest.

Logically speaking, this thunder spirit is only at the level of Great Perfection of the Earth Supreme, and naturally inferior to myself who has now been promoted to the Quasi-Heaven Supreme through secret techniques.

But the tricky thing is that the attack of this thunder spirit is wrapped in a strange sound wave force, which directly attacks the soul, making it impossible to defend against.

Caught off guard, he suffered a loss.

"In that case, I won't confront you head-on."

"Celestial Emperor Sword!"

Lu Chen waved his hand, and with a whoosh, a streak of light flashed across, and the Emperor of Heaven's Sword floated in the palm of his Dharma body.

Immediately, his mind moved, and the light on the three-foot-long Emperor Sword suddenly increased, and its size instantly increased, turning into a huge crystal sword dozens of feet in size, floating in front of him.

Tianyan Dharmakaya held the Emperor's Sword in both hands, and mysterious and obscure crystal light patterns appeared all over his body. An indescribable ancient aura emanated from the light patterns, giving people a strong sense of oppression.

The supreme magical power, the Buddha divine pattern!

Immediately, the Dharma body swung the sword, and in an instant, a dazzling sword light shot out. Countless crystal light patterns emerged in the sword light, intertwined and entangled together, turning into a crystal sword light.

boom!
The sword light carrying the Buddha divine pattern fell down with a bang, and with a destructive force, it slammed into the giant shadow of thunder!
"Roar!"

The giant thunder shadow roared, and the aura of his body burst out like a storm, and the thunder spear in his hand suddenly shot out.

call out!
The Thunder Spear shot out from the air like a giant dragon. In the blink of an eye, it collided with the crystal sword light, and then a violent spiritual power storm swept out.

boom!
The two collided with each other, and the sword light instantly cut the spear into pieces. Wherever it passed, the space shattered, and countless space fragments were directly shattered into endless light spots.

call out!
Immediately afterwards, the sword light pierced into Lei Ling's body, and Lei Ling let out a terrifying roar. Countless mysterious crystal runes appeared on the surface of its body, and the originally violent spiritual power fluctuations disappeared without a trace in an instant.

Click!

At the same time, layers of broken crystals began to spread from the wound, and in the blink of an eye, the huge thunder spirit that was hundreds of feet tall was transformed into a crystal sculpture.

"It's done."

A hint of relief flashed in Lu Chen's eyes, and the Emperor Sword in his hand pointed directly at the Supreme Heart Demon Seal on the altar.

"I know you are intelligent and can understand human speech. I'm not afraid of you knowing that I am the descendant of the ancient Heavenly Emperor. Since you once followed Senior Heart Demon, you must have heard of the Heavenly Emperor's reputation."

"Now that your master has disappeared, and the evil tribe outside the domain is ready to make a move, why do you have to imprison yourself here? Why not come with me and fight against the evil tribe together?"

The Supreme Heart Demon Seal trembled slightly, as if responding to Lu Chen's words.

A moment later, a strange idea emerged in Lu Chen's mind.

"Heavenly Emperor... the descendant of the ancient Heavenly Emperor? No wonder you can wield the Heavenly Emperor Sword."

"But in ancient times, the Emperor of Heaven and my Thunder Palace were not allies. In fact, you guys from the Heavenly Palace even called for the killing of my Lord. Why should I help you?"

When Lu Chen heard this, a look of astonishment flashed in his eyes, and he was quite surprised.

I have never heard Mandala mention this matter. It seems that she is not omniscient and omnipotent.

Immediately, his heart moved, and he said in a deep voice, "The events of the ancient times are now a thing of the past. Now that we are faced with a formidable enemy, if we still cling to past grudges, it will only give the evil tribes from outside the domain an opportunity to exploit. If you have any intelligence, you should understand that cooperation is the only way out."

"If your master were still alive, he certainly wouldn't want the world to be devastated."

The Supreme Heart Demon Seal fell silent again, as if weighing the pros and cons.

A moment later, another thought came to Lu Chen's mind.

"Okay, I can cooperate with you temporarily, but I have one condition."

Lu Chen's eyes fixed, and he asked in a deep voice, "What are the conditions?"

"I want you to swear in the name of the Emperor of Heaven that if you use my power, you must help me find the remaining soul of the inner demon Emperor Lei and help him be reborn."

Upon hearing this, Lu Chen frowned slightly, and then asked with some doubt: "Is the Heart Demon Thunder Emperor still alive?"

"Are you sure? It's been so many years..."

The Supreme Heart Demon Seal trembled slightly, and another thought came out.

"You don't need to worry about this. Just agree to this, and I will be at your disposal until you recover his remaining soul."

"Okay, I promise you."

Lu Chen thought for a moment and then nodded.

As soon as the words fell, the Supreme Heart Demon Seal suddenly burst out with brilliant light, turning into a stream of light and flying towards Lu Chen.

Lu Chen stretched out his hand and grasped the flowing light in his hand. He immediately felt a mysterious connection that connected him to the Heart Demon Seal in his hand.

The Supreme Heart Demon Seal, recognize the master!
