Robbie smiled and shook his head:
"To let this go unchecked is irresponsible. If Zang truly resurrected, Outland will face its doom. We must nip him in the bud."
Robbie took out the Node Key and activated the largest node.
With a flash of light, Robbie and Krasus appeared deep beneath the Zangarmarsh.
This is an unimaginably large cave, with an eternal light source floating directly above it, like a small sun that has been burning for countless years and has yet to go out.
Below is a shimmering lake with clear water where you can see giant red fish, more than ten meters long, swimming around.
In the center of the lake is an Island, lush and verdant, with countless pavilions and towers, and at its very center stands a magnificent golden palace.
An artificial mini-sun, a complete ecosystem, a palace on the central Island, and a distinctive Titans style.
Krasus was astonished by what he saw; who could have such a grand gesture?
Robbie looked up at the small sun overhead. "Did the Arakkoa Empire suddenly decline? It remains a mystery to this day; perhaps this is the answer."
The Arakkoa established the powerful Apexis Civilization, a civilization that utilized light energy to its fullest potential.
Some say the Arakkoa declined because of endless civil wars, while other scholars analyze that it was because their energy source was taken away.
Countless Apexis Crystals were embedded around the small sun.
"According to ancient Legendary, Aggramar once visited Draenor," Krasus whispered.
Robbie shook his head, but didn't explain, changing the subject instead:
"Some scholars believe that the Arakkoa stole technology from the Titans and created the Apexis Civilization. But how could Titans technology be so easily stolen? Look here, I suspect that the Titans taught the Arakkoa the technology with the aim of building this palace. Once the palace was completed, Apexis declined overnight because they had become useless."
Krasus stroked his chin and said, "A reasonable guess."
It's not surprising that an ancient Titans built a secret palace in Draenor to secure his escape route.
"Let's go, there are more secrets in the palace."
Robbie and Krasus landed on the central Island, which was filled with Titans Constructs that faithfully carried out their orders and maintained the Island's ecosystem.
The palace at the very center was filled with extraordinarily large tables and chairs, as if they belonged to a kingdom of giants.
Robbie went straight down to the basement.
Following the winding Passageway, the two arrived at the deepest part of the underground, the central control room.
Judging from the decorations and signs of wear, the central control room is older than the outer palace.
In the very center of the control room sits a metal heart the size of a small mountain.
Nine tall stone pillars stood around the perimeter, covered with obscure Runes that continuously drew energy from the metal.
For countless years, the heart of the rock has continued to beat slowly.
Beside the heart, a red vine broke through the ground and pierced straight into the metal heart.
A red substance flowed through the vines; it was the flesh and blood of the Orcs.
Robbie circled the metal heart, which was made of an unknown metal and flowed with a dazzling magical light.
Unfortunately, a small portion of the metal heart showed signs of flesh-like decay, with dark red veins resembling ugly scars.
"What did you feel?" Robbie asked Krasus.
Krasus frowned deeply. "I sense boundless hatred, a vengeful spirit lurking within my heart."
Robbie nodded. "That's exactly what we're after. If we let this vengeful spirit grow unchecked, the Outland will be destroyed. The Orcs' flesh and blood are accelerating its growth."
Krasus was startled. "Could this be Jaina's purpose from the future?"
The sacrifice of a million Orcs would have had unimaginable consequences, but thankfully the Node Key did not fall into Jaina's hands.
Robbie shouted, "Come out, vengeful spirit!"
Golden Holy Light descended, penetrating deep into the metal heart, accompanied by a piercing scream.
"It hurts! It's Holy Light! Who has disturbed my eternal slumber?"
A chilling wind howled, and countless dark shadows emerged from the flesh and blood veins of the metal heart, coalescing into a black humanoid shape.
The humanoid form has thick limbs and huge spikes protruding from its skin, much like the ancient creature Magnaron from Draenor World.
"Hate! An overwhelming hatred! I will destroy everything here, destroy the Order created by the Titans!"
A powerful aura of resentment filled the central control room, and Robbie and Krasus could clearly sense his hatred.
"Who are you?" Robbie asked.
The black humanoid trembled and sobbed as it spoke:
"Who am I? Who am I really? I remember now, long ago I had a name, they called me Grond. I had just achieved a great victory, ending a battle that had lasted for a thousand years, when a Lightning struck from the sky and my body was torn to pieces."
"Grond, it's him!" Krasus exclaimed in surprise.
Gorgrond, the Titan Aggramar, infused the highest peak of Draenor with the powerful energies of earth, fire, water, and wind, creating the ancient life form.
Orcs, Ogres, Cyclops, and Gronn are all descendants of Grond.
According to research, after Grond destroyed the spore swarms Zang and Nayanu, he was defeated by the last spore swarm, Potaan. His corpse formed Nagrand, and the Elemental Power within him formed the Throne of the Elements.
Could there be another hidden story behind this?
The Lightning that fell from the sky was clearly the work of the Titans.
Robbie chuckled and said, "If the Titans were to kill you, they would leave no remnant soul behind. You are merely a spirit born of hatred; your hatred is meaningless."
"Shut up, you all understand nothing."
The black humanoid figure exuded a chilling aura.
"Leave this place, or become nourishment for me."
Krasus said in a trembling voice, "Run! We are no match for him."
Robbie smiled confidently and said, "Don't worry, look at this."
Robbie raised the Node Key, and the nine stone pillars surrounding the metal heart hummed, resonating with the Node Key.
The sound of machinery echoed in the control room:
"Control room key found. Titans defense activated. Unidentified vengeful spirits have appeared. Urgent cleansing is needed."
The black humanoid panicked. "Stop! I surrender! I was wrong! Damn it! No!"
The nine stone pillars simultaneously emitted a golden light, and in an instant, the black humanoid figure was vaporized.
Krasus scratched his head blankly. "That's it?"
"It's not over yet; the real trouble is yet to come."
Robbie arrived at a corner of the metal heart, the cleanest area, with no trace of flesh and blood nearby.
There is a keyhole on it, which is just right for inserting the Node Key.
The outer shell of the metal heart slowly opened, revealing a device resembling a control console.
Krasus stared at it for a long time. "You understand the Titans's control panel?"
Robbie shook his head. "I don't understand. Based on general experience, we should start with a reboot."
A red button, resembling a reset switch, made Krasus shake his head.
"No, no, you need to think this through. What if it's the switch to destroy Draenor? We've already destroyed the vengeful spirits; it's time to leave."
"I'm sure this is a reboot." Robbie pointed to the marks on the button. "Quietly, this has been pressed multiple times by a thick finger."
Robbie pressed the red button.
The mechanical voice sounded again, "Draenor World, Life Evolution Device activated."
