Bai Zisheng nodded and said, "Then study it well. I can't help with the Formation, but if you need to fight, you must call on me."
"Right," Mo Hua agreed.
In the following days, Mo Hua devoted his time to studying the Formation patterns on the zombies' bodies.
The Formation on the bodies of both the Walking Corpses and the Iron Corpse, combined, formed a rather complete and coherent system where Spiritual Power could circulate with a beginning and an end, and the Formation Patterns echoed each other – a first-grade, twelve-patterned Ultimate Formation.
This Formation was the Spiritual Pivot Formation.
Several days later, Mo Hua sat in the courtyard, staring at a Formation in front of him, somewhat dazed.
He had already mastered drawing this Ultimate Formation.
This was far beyond Mo Hua's expectations.
Mo Hua originally thought that mastering the Spiritual Pivot Formation would, at the very least, require time to understand the unique patterns of Spiritual Power circulation, not to mention any special Taoist meanings.
But the Spiritual Pivot Formation came to him surprisingly quickly.
After just a few days, he had mastered the Formation.
Mo Hua tried inscribing the Spiritual Pivot Formation onto a toy wooden tiger. This tiger was a gift from Old Kui.
Once the tiger had the Formation painted on it, Mo Hua inserted a Spirit Stone into it, activated it with Spiritual Power, and found that he could control the tiger's movements with his Divine Sense.
It could walk, sit, run, leap, crouch, and jump; it was as lifelike as could be.
Bai Zisheng and Bai Zixi, upon seeing it, found it quite novel.
Typically, toys in the Cultivation World could move on their own.
In Tongxian City, Mo Hua had bought many such toys – if you inserted Broken Spirit Stones into them, the dolls would clatter their way forward under the motivation of Spiritual Power.
But their movements were mechanical and fixed.
That was different from what Mo Hua had just created.
This wooden tiger could perform many subtle movements under the control of Divine Sense.
To an onlooker, the difference might not seem vast, but the involved Formations were worlds apart.
One required only a few Formation Patterns and was a simple Formation.
But the other needed a beyond-grade, first-grade, twelve-patterned Ultimate Formation.
Mo Hua studied the principle of the Spiritual Pivot Formation more closely.
He discovered that Instructor Yan was right. At its core, the Ultimate Formation was indeed about "control."
It transformed Spiritual Power into finer strands to perform detailed controls through these threads of power.
But was that all there was to it?
Had he only grasped the surface of the Formation?
Were there deeper elements to the Formation that he had not yet understood?
Mo Hua furrowed his brows.
Beyond understanding the rules of the Spiritual Pivot Formation, he also realized there was an issue with this Formation.
It seemed like the Formation was still not the complete Spiritual Pivot Formation, even though it was already effective.
Why did it seem incomplete?
Mo Hua thought for a long time but could not figure it out.
Not until he remembered the out-of-control Iron Corpse did he have a sudden epiphany.
The Iron Corpse's loss of control was a "loss of control" under the influence of the Formation.
In other words, the Iron Corpse controlled Walking Corpses while also being controlled by something else.
The Spiritual Pivot Formation on both Iron Corpses and Walking Corpses could essentially form a Spiritual Power cycle, achieving the effect of the Spiritual Pivot Formation.
However, atop the Iron Corpse, there was another tier of Spiritual Pivot Formations.
This tier of Spiritual Pivot Formation was a higher component of the overall structure.
In other words, what Mo Hua currently understood was merely the intermediate and lower levels of the Spiritual Pivot Formation.
This hierarchical structure of Formations exceeded Mo Hua's previous understanding.
"Formation mastery is indeed profound and vast," Mo Hua sighed once more.
If his conjecture was correct, the so-called Spiritual Pivot Formation was not simply a Single Formation.
It was a special type of Formation system that branched down from one Formation into a hierarchical structure that spanned from top to bottom, from high level to low level.
All Spiritual Pivot Formations belonged to the same category, yet controlled with distributed authority at different tiers.
The one on the Walking Corpses was the lowest level of Spiritual Pivot Formation, with the least authority, capable only of being controlled by others.
The one on the Iron Corpse was a level higher, with more authority able to control the Walking Corpses.
Considering this, there had to be something controlling the Iron Corpses!
Was it an Evil Artifact, a Cultivator, or another zombie that controlled the Iron Corpse?
And this unknown item, person, or corpse, within the hierarchy of the Soul Pivot Ultimate Formation, held the highest authority, capable of dominating all others, controlling every zombie that had the Spiritual Pivot Formation on its heart meridian.
It commanded all Walking Corpses and Iron Corpses!
The mere thought sent a chill through Mo Hua.
