Longevity Technique’s Ultimate Yin Cultivation Method – Innate Ultimate Yin True Qi

After deciding to cultivate his second martial soul, Nangong Lingyun began researching how to develop it further.

Among the five major attributes of the Chaos Spirit,Darkness, Time, Death, and Emotion all fundamentally rely on the mind.

Besides being complementary, traits like Absolute Insight, Fate Interference, Necromancy, and Divine Physique Manifestation are all heavily related to the strength of spiritual power.

Douluo is a world with settings that can only be described as ridiculous.Releasing force exceeding 100,000 jin (50 tons, or even 100 tons if measured in kilograms) can shatter space.

Things like Time and Fate—just by having strong enough spiritual power, one could influence them. At this point, they're practically secondary attributes or byproducts of the spirit.

No matter how absurd it feels, these are still the unchangeable rules of this world.

So, in the original plan, enhancement and application of the spiritual attribute occupied at least four spirit rings.And these skills would require massive amounts of extra "爽點" (cool points), with each one being unique, even if upgraded to million-year quality.

They were:

Mirror Flower, Water Moon (Illusion)

Telekinesis

Mind Control

Turning Illusion Into Reality

The remaining five rings, apart from the Martial Soul Avatar, were assigned to the Darkness, Time, Death, and Emotion attributes—one each.

After pondering for a moment, Nangong Lingyun called out in his mind:

"Diao Chan?"

"Respected Master, I'm here!"

That familiar voice, still carrying a playful and teasing tone,Just that charming inflection could stir the imagination, as if tens of thousands of words of fanfiction and several hard drives' worth of "educational videos" suddenly popped into one's head.

But his heart remained calm and steady as he thought:

"Begin configuring the first soul skill of the Chaos Spirit. Name: Mirror Flower, Water Moon.Choose the maximum age both I and the martial soul can endure, prioritizing quality and effectiveness."

Spirit Ring Effects (Passive):

Massively enhances spiritual essence, including but not limited to the quality, purity, amount, and utilization rate of spiritual energy, as well as the controllability of related abilities.Enhancement should be no less than that of a perfect soul ring produced by a 100% affinity Supreme God-level spiritual beast.

Greatly develops and evolves the martial soul's spiritual attributes, including all spirit-related traits and any other skills potentially affected by spiritual radiation.Development degree same as above.

Grants strong charm and illusion abilities, thought guidance, control over the five senses, illusion-world creation, and total control over illusion content.

Skill Effects (Active):

Instantly nullifies the opponent's soul, consciousness, and spirit-based defenses, traits, and skills.

Instantly strips the target's sensory perception of the outside world at the spiritual level, and replaces it seamlessly with one's own desired content. Nearly impossible to detect.

On top of the above, enables spiritual attacks, mind control, memory implantation and erasure, etc.

"Respected Master, do you confirm this configuration?Please review all terms, check for errors, assess resource consumption, and ensure no omissions before proceeding."

This reminder from Diao Chan was something he had set up himself.After triple-checking everything, Nangong Lingyun confirmed internally:

"No mistakes. Confirm."

In the next moment, the Chaos Spirit Martial Soul automatically attached to his body, and a white halo began circling above it.

Accompanied by a euphoric sensation, he could clearly feel his spiritual power expanding and strengthening rapidly.

That halo instantly turned yellow, then quickly shifted to purple,and within less than three minutes, it began to flash with intense black light.

The age of a soul ring isn't only determined by martial soul, physical body, spirit, and affinity. The quality of the ring itself is crucial too—Generally, the higher the quality, the lower the age, and vice versa.

But all the soul rings of Nangong Lingyun's two martial souls were special-grade and of exceptionally high quality.As a result, the age maxed out at only 21,000 years.

However, based on experience from the Primordial Divine Physique,once all four rings are attached, the earlier ones will unlock additional enhancement space.

Without pause, Nangong Lingyun began setting the remaining skills.

System produced—quality guaranteed.There's no such nonsense as unstable soul power, absorption cooldowns, or time gaps between adding rings.

Thirty minutes later, the second skill [Time Control], third skill [Mind Control], and fourth skill [Darkness Control] were all configured.

All four soul rings were now exactly 36,000 years old.

The Chaos Spirit still hadn't been developed and honed as long as the Primordial Divine Physique, after all.

Without a word, Nangong Lingyun entered the virtual space, eager to test the power of his second martial soul—especially the Time attribute.

But within thirty seconds, his brow began to slowly furrow.

Apparently, some of the abilities were so broken that their actual performance fell drastically short of expectations.

Time Stop: Consumes 10% of spirit power for one use. Can freeze a Golden Lion-Tiger for 0.16 seconds, but requires 8 seconds of charge-up.

For a typical level 44 Soul Sect, no charge would be needed, only 5% spirit power, and it would last about 3 seconds.

Time Acceleration / Deceleration:Applies to oneself or other entities, but the limit and consumption vary depending on energy level.

For the Golden Lion-Tiger:Maximum ±104% time flow, and maintaining this intensity consumes about 1% of spirit energy per second.

Time Reversal / Traversal:Still unusable.

"The ring age is still too low..."

Nangong Lingyun sighed internally and exited the virtual space.He had expected this. Time-based powers, while extremely strong, come with equally ridiculous limitations, complexity, and energy demands.

Also, spreading too thin was part of the issue.

If he had only chosen Time Stop or Acceleration, the results would've been vastly different.

Still, he had no regrets.

Developing and cultivating the second martial soul had always been on the agenda—it just happened a little earlier than planned.

After all, the little kitty was about to show up, and the Chaos Spirit's Darkness attribute would pair perfectly for a Martial Soul Fusion.

The Time ring had to be set this way—A single OP skill might feel good now, but when strengthened to a million years or more, being limited by the number and potential of abilities would come back to bite him.

Mastery, on the other hand, encompasses all related abilities—essentially no ceiling.

That thought alone made Nangong Lingyun's brow relax again.

His cheat system was far from done anyway.

"In that case, let's begin cultivating the Longevity Technique's Ultimate Yin Inscription.The Innate Ultimate Yin True Qi should boost both the soul ring limits and their actual performance."
