Full health is the kill threshold, no matter if you're a god or a demon!

Two days have passed, and the scene here has changed.

Under Arachne's command and with the diligent work of the spider elves and abyssal dwarf slaves, the main structure of the Hall of Slavery has been completed and is now in use, continuously converting dwarf slaves.

In addition, the first thing to be completed was the "Lord's Secret Chamber" in the fifth-floor library.

This place has been specially reinforced by Arachne, with layers upon layers of concealment, protection, and spatial stabilization runes laid out, making it the safest place in the floating city and the location closest to the core energy vein of the psionic energy.

Liu Nian was very satisfied with the progress of the project. He went to the newly built secret room, activated the surrounding protection, and then took out the Prism Skill Stone.

Liu Nian enhanced the mad beast's form with prismatic enhancement.

Originally, he wanted to enhance Endless Fury the most, but after acquiring Heart of Deception, his survivability was greatly enhanced, so the priority of this skill was put on hold.

Any of the prismatic enhancements would result in a qualitative change, but considering that the Demon Bear Clan could instantly enhance themselves tenfold using the Heart of Elune, Liu Nian was also somewhat tempted.

Looking at his skills, if he could double his combat power, then the transformation skill—Beast Transformation—would be the best choice.

[Prismatic Skill Stone Takes Effect]

[Effect 1: The Berserker Avatar form removes the transformation time limit, and the user's size increases tenfold after transformation, gaining physical and control immunity.]

[Effect 2: The transformation time of the Berserker Avatar is reduced to 20 seconds, and you are invincible during the transformation.]

[Effect 3: The Berserker Avatar is now replaced by the Dragon Form. Dragon Form (lasts 10 minutes, 24-hour cooldown): Maximum health increased by 500%, magic immunity, movement mode changed to flight, you can still use your character's original skills, and additionally gain the "Elemental Breath" and "Celestial Manipulation" skills.]

"What's there to think about... I am a descendant of the dragon!"

After receiving this result, Liu Nian looked at the two skills.

Elemental Breath involves exhaling elemental attacks through the mouth. Unlike Dragon Breath, this skill emits a beam of energy, and the user can freely choose to release lightning, fire, water, or other elemental energies.

The damage is based on ability power and health, and it can keep firing as long as you have enough energy.

As for celestial manipulation, it means being able to control natural weather, such as sending down thunder, torrential rain, or strong winds.

This skill is also based on ability power, but Liu Nian thinks that the main purpose of these two skills is to show off, rather than to deal damage...

Well, no matter what, this prismatic color is worth it.

After completing the Prism upgrade, Liu Nian then studied the [Heart of Deception].

With a thought, a chaotic halo quickly enveloped his entire body.

A slight, strange sensation, as if his body had been reshaped, washed over him. The light faded, and another "Liu Nian" appeared before him.

The exact same appearance, eyes, aura, even the simple clothes are exactly the same. This is the self-reflection under the "perfect disguise," or rather, the "deceptive body."

As soon as this body appeared, Liu Nian felt his consciousness switch into this mirror image.

He moved his hands and feet, performing several complex movements without any hesitation; his body felt exactly the same as his own.

Then, he removed all the equipment he was wearing on his original body and put it on the mirror image.

Then he put two pieces of the Immortal King set from his backpack onto his main body, and put some important items that he didn't need for the time being into his main body's backpack.

From now on, the one active outside will be "Mirror Image Liu Nian".

Liu Nian found Arachne, who was supervising the construction of another site.

"Master, you're back." Arachne immediately stopped what she was doing. "What are your orders?"

"Can you tell if I'm any different from before?" Liu Nian asked.

Arachne paused for a moment upon hearing this, then his eyes gleamed with arcane light as he scanned the person from head to toe several times before finally shaking his head: "I can sense that you are stronger than before, but you are no different from the others."

Liu Nian felt relieved. If even Arachne, an eternal being, couldn't see through it, then it meant that this deceptive body was indeed amazing.

"Get ready, come with me to a place," Liu Nian said. "The Rust Dynasty, the territory of the Silverscale Naga. They control the 'Tidal Core,' and I've secured an opportunity that might allow us to use its power to repair the Psionic Core. This will require your expertise to assess and implement the necessary procedures."

Arachne's compound eyes lit up instantly: "A tidal core? Excellent! Master, if it's a water-attribute eternal core, then the chances of repairing the psionic core are extremely high! I'll prepare the necessary knowledge and tools right away!"

A moment later, Arachne, having made all the necessary preparations, followed Liu Nian through the teleportation array to the Rusted Dynasty.

When the eternal Arachne appears accompanied by spatial fluctuations, the resulting tremors are unimaginable.

The immense pressure was undisguised; it was the suppression of an eternal being. The nearby Naga guards tensed almost instantly, their weapons instinctively pointing at her as she suddenly appeared.

The Deepwater Matriarch was immediately alerted and rushed over with several Naga elders.

When she saw Arachne standing quietly beside Liu Nian, her aura as deep as the ocean, her dignified face revealed an undisguised look of surprise.

"Lord Liu Nian, who is this gentleman...?"

"My technical advisor and partner, Arachne," Liu Nian introduced calmly. "She has an excellent understanding of psionic cores. She is the most suitable person to lead the assessment of contact between psionic cores and tidal cores."

Arachne bowed slightly, speaking in some ancient common tongue: "Greetings, leader of the Silverscale Naga. I have come to restore the core; may our contact be of mutual benefit."

An eternal being serving as a "technical advisor"?

The Deepwater Matriarch and the elders exchanged glances, their shock beyond measure. Their evaluation of Liu Nian had to be raised even higher. His ability to command an Eternal-level being spoke volumes.

The lingering doubts and scrutiny completely vanished after Arachne's appearance.

Collaborating with such entities presents both risks and opportunities, but clearly, the opportunities outweigh the risks.

"Welcome, Lady Arachne." The Deepwater Matriarch's attitude became even more solemn. "Your arrival adds even more significance to this technical exchange. Please follow me; we have prepared a place to access the outer array of the 'Tidal Core'."

Under the personal guidance of the Deepwater Mother, Arachne, accompanied by several Naga elders, began a cautious exploration and preliminary energy resonance test of the outer array of the Tidal Core.

This work requires time, meticulous operation, and a deep understanding of the eternal laws of creation; it cannot be rushed.

Liu Nian naturally wouldn't wait idly here. He handed the Psionic Core to Arachne, gave her a few instructions, and then, through the Deepwater Mistress, conveyed the message of temporary departure to the Sun Devourer, who was still digesting the harvest in the quiet room. He then returned to the Floating City.
