Rustle, rustle.

All kinds of meridians and blood vessels are circulating within the body.

This is the most intricate cycle.

Because it is so delicate, so susceptible to issues, performing "heart bridge surgery" on it is far more difficult than other cycles.

For others, the outcome is nine deaths and one life!

Even if one succeeds, it requires meticulous effort, possibly taking hundreds of years to slowly open up the meridians.

However, fortunately, Ning Zheng is lucky enough.

No matter how thin the meridians are, so what?

Charging recklessly!

But the speed is still slow.

In the previous realm, it only took a few hours to a day; now, under this meticulous effort, it has surprisingly taken three full days.

Sigh!

"Succeeded, One Heart Six Apertures Realm."

Ning Zheng slowly opened his eyes and looked at the blacksmith information on the forum:

"However, the outside world has been quite turbulent these few days, with various forces stockpiling food... Meanwhile, in the Tomb of Longevity, a group of mad dogs frantically digging graves for the past three days, it's pretty ruthless, almost dug it all up."

Ning Zheng looked at the Longevity Imperial Mausoleum, now a piece of ruin, and twitched his mouth slightly.

This is why you shouldn't underestimate these Two-Phase Realm demolition teams.

Their Dharma Aspect can transform into giants; a horizontal and vertical swipe of their hand equals mountains, making land clearing too convenient, even more suitable as demolition teams!

"However, not much happened in the past three days."

Ning Zheng's gaze was calm, like a mortal, and the aura surrounding him was tranquil.

This is the interior reflective ability of a perfect cycle.

A perfect cycle naturally evolves into a Leakless Body, not leaking even a tiny bit of aura.

To cultivate, is to refine cycles, an evolution of the undying!

The One Heart Realm is heart bridge surgery, bridging cycles to the heart, using the heart as a central hub to clear each realm's cycle.

Thus,

Humans have five viscera: heart, liver, spleen, lungs, and kidneys, yet in the Four Viscera Realm, only four are cultivated, leaving the mortal heart as a fatal flaw.

The cultivator's head isn't a weakness, but the heart is as fragile as that of a mortal.

Countless have died in battle due to this mortal heart, yet no one trained in advance to mend this vulnerability of the heart!

Because training the heart prematurely means the heart cannot bridge the cycles in later realms; every cycle remains independent.

Unable to clear other cycles for a lifetime, all undying cycles become a solid piece, never able to cultivate the One Heart Realm.

"The five viscera, only cultivating four... truly the ever-evolving cultivation system of ancestors, it's perfect."

Ning Zheng constantly marveled at the ingenious thoughts involved, yet a slight doubt arose:

"But in this system, the One Heart Six Apertures Realm, connecting the heart with six cycles, is that all?"

Ning Zheng didn't think so.

Fortified by Qi Fortune, he could vaguely perceive a degree of fortune and misfortune, vaguely sensing there is still another element.

One Heart Six Apertures isn't the limit.

The true limit should be an undying Seven-orifice Exquisite Immortal Heart!

Humans have... seven cycle openings.

"But where is the seventh cycle hidden in the body?"

Ning Zheng was somewhat puzzled.

The Five Elements, the Four Viscera... every cycle has already been completed.

Everything has undergone 100% cycle refinement, he couldn't find a trace of blankness.

Initially, Ning Zheng wanted to wait a bit, as part of the waiting party, to see if Xin Xichen, this academic giant, could figure it out.

But now, as he was on the verge of a breakthrough, he couldn't wait anymore!

Even:

Ning Zheng suspected that Xin Xichen had already researched it secretly and simply didn't want to reveal it.

He started evaluating how much Qi Fortune Value would be needed to deduce this realm.

[One Heart Seven Apertures Realm: 10 million Qi Fortune Value].

Ning Zheng raised his eyebrows, showing a hint of confusion: "Why so little? Only charging me an extra 5 million?"

To develop an unprecedented new realm, logically, it shouldn't be this low.

So, perhaps this seventh cycle already exists within himself...

And everything is ready, just missing breaking a paper-window, thus the low value.

Ning Zheng raised his eyebrows, revealing a contemplative look, "In other words, the seventh aperture... likely already researched, existing within me all along."

"And this cycle might not have existed in ancient times, only recently emerged and perfected... But Xin Xichen hid the external information about the seventh cycle."

Ning Zheng thought about what cycles appeared in this era?

Suddenly, a thought flashed through his mind.

Yin Yang Spirit Root Cycle!

Five Elements Spirit Root Cycle!

Spiritual Roots are themselves an internal body cycle.

"I should have thought about it earlier." Ning Zheng's eyes flashed a trace of color.

Why do the Immortal Spirit Roots need to be painstakingly researched by the Xin Dynasty Royal Family emperors?

Because Xin Xichen disclosed: the limit for Celestial Spirit Root cultivators is the Self-Transformation Realm.

If one wants to break through to the realm above Self-Transformation to become Immortal.

There must be...

Immortal Foundation, Immortal Spirit Root.

So, Xin Xichen crazily slaughtered his kin and even indulged in internal strife to study Immortal Spirit Roots, leading to chaos in the Xin Dynasty, inciting Jiu Shui's rebellion!

The importance of Immortal Spirit Roots is unquestionable.

But how are Immortal Spirit Roots applied? What principles allow individuals to break to a higher realm?

Now Ning Zheng figured it out.

It's for completing the body's seventh cycle.

Root Cycle.

Only in the One Heart Realm, by casting a Seven-orifice Exquisite Heart, can one have the chance to break through to the realm above Self-Transformation.

"Haha, Xin Xichen is truly vile."

Ning Zheng chuckled coldly, "He doesn't reveal the information, fearing most cultivators won't clear the seventh opening in the One Heart Realm, leaving a flawed foundation, with the seventh cycle not integrated with the heart... Thus, most Nine-State cultivators' limits are the Self-Transformation Realm!"

This is information monopoly.

If Ning Zheng weren't smart enough, failing to clear the seventh cycle and breaking directly to Self-Transformation Realm, he'd be wasted.

The foundation would be incomplete...

To mend it, one would have to die once, become a Ghost King, and live a third life to mend the foundation.

This...

Kinda simple too?

Ning Zheng touched his chin, "Seems that even if I've been tricked, I can rely on Qi Fortune to mend this foundation, but others are practically wasted, living another life isn't easy for them."

But now that the information is received, Ning Zheng naturally intends to cultivate to perfection in the One Heart Realm.

[One Heart Seven Apertures Realm: 5 million Qi Fortune Value].

Seeing the number change, Ning Zheng smiled instantly.

A layer of paper-window worth 5 million Qi Fortune Value!

Although not much, relying on his intellect and thoughts to deduce Xin Xichen's hidden scheme is an incomparable achievement.

Through reasoning, gaining a blood profit of 5 million!

Even though he figured out Xin Xichen's backup plan, Ning Zheng had no intention of publicizing it for the world's benefit.

Screw as many as possible.

The cursed, Phoenix Yi, and even major forces likely know but also don't disclose... to prevent others from competing with them.

In short, the information about the breakthrough should only be shared with those around him, he isn't the Holy Mother.

"Slowly consolidate cultivation, and after a while, clear the seventh aperture cycle!"

Ning Zheng touched his chin, shook his body, stood up to exercise a bit, "However, the seventh aperture cycle... Yin Yang Cycle, seems somewhat imperfect?"

Ning Zheng pursues perfection.

Perhaps he needs to cultivate the Five Elements Spirit Root Cycle, transforming into Seven Colors Spirit Root Cycle.

With the most perfect posture, Seven Colors Spirit Root Cycle, clearing the seventh cycle, that's the strongest.

"Preparing the Five Elements Spirit Root is really necessary!"

Ning Zheng secretly made up his mind:

"But the cost is incredibly high, cultivation is just burning money! To forge a strong foundation, the expense is dozens or even a hundred times that of same-tier cultivators, potentially emptying a force's resources, previously the Yin Yang Immortal Spirit Root of Shadow Crocodile, Human God Flower spent a large fortune."

"Thankfully, a big haul from the imperial mausoleum provides ample resources, allowing for a start on the Five Elements Celestial Spirit Root that suits me!"
