Inside the iron coffin, an Iron Corpse was sealed.
Iron Corpse was one level higher than Walking Corpses.
Walking Corpses had pale and rotting flesh and contained Corpse Poison. Although fierce and fearless of death, their strength was quite ordinary. They primarily relied on their numbers and Corpse Poison to gain an advantage.
The skin of an Iron Corpse was an iron blue, much like cast iron, and their strength was greater, comparable to that of a cultivator in the initial stage of Foundation Establishment.
Crafting an Iron Corpse was more costly, and it took more time.
Similarly, controlling an Iron Corpse was also more difficult.
Only a Foundation Building Cultivator, relying on the Divine Sense of Foundation Establishment and using the Corpse Controlling Bell as a medium, could control an Iron Corpse with relative stability.
For Corpse cultivators in the Qi Refinement Realm, whose Divine Sense was insufficient, controlling an Iron Corpse for an extended period could easily lead to its loss of control and result in a backlash.
That's why Zhang Quan intended to consecrate the bell, to enhance the stability of corpse control by borrowing Divine Thought.
Mo Hua opened the iron coffin.
An Iron Corpse with blackish-green skin and ferocious iron features lay inside with its eyes closed.
There was a rich Corpse Qi emanating from it, and within its flesh flowed a greenish Corpse Poison.
Bai Zisheng, gripping a long spear, placed the tip on the Iron Corpse's forehead to prevent it from losing control and lashing out, potentially injuring Mo Hua.
Bai Zixi was also holding a golden longsword, standing by Mo Hua's side.
Using a dagger, Mo Hua cut open the Iron Corpse's shirt to reveal its iron-blue, sinister chest.
There was nothing on the surface of the chest.
However, Mo Hua's eyes lit up.
He had indeed sensed the aura of the Ultimate Formation.
With the dagger, Mo Hua made several cuts on the Iron Corpse's chest, but the skin was so tough that not even a scratch was left.
Mo Hua sighed and could only hand the dagger to Bai Zisheng, saying,
"Senior brother, it's up to you now."
Bai Zisheng took the dagger and said,
"Step back a bit."
Mo Hua obediently retreated several feet.
Bai Zisheng then activated his cultivation technique, wrapping the dagger in golden Spiritual Power, and carefully started cutting into the chest of the Iron Corpse, peeling off the skin.
Underneath the skin, the flesh was dark green, and the Corpse Poison was dense.
And on top of the flesh was indeed a red Formation, complex and profound!
"Mo Hua, come take a look!"
Bai Zisheng called out.
Mo Hua hurried over and leaned in to take a closer look.
After inspecting for a while, his eyes brightened.
Yes, it was indeed the Spiritual Pivot Formation related to Walking Corpses, but the Formation Patterns were slightly different.
He quickly took out paper and pen, and began to jot down the Formation Patterns.
But as he recorded, Mo Hua's expression turned a bit grim.
He glanced at the Iron Corpse and said in a serious tone,
"Senior brother, this Iron Corpse, it's about to lose control..."
Bai Zisheng was taken aback, "How do you know?"
Mo Hua's gaze was profound, "The Formation is operating, someone is controlling this Iron Corpse… 'Losing control'..."
Startled by the words, Bai Zisheng immediately took out his spear and pinned the Iron Corpse within the iron coffin.
Simultaneously, the Iron Corpse abruptly opened its eyes.
Their red eyes were brimming with bloodthirst and ferocity.
Its arms stretched forward, its iron claws sharp and long, tipped with Corpse Poison, as it rigidly tried to stand up.
But its body was pinned down by Bai Zisheng's spear, making it unable to break free for the moment.
As it struggled, the Blood Formation on the Iron Corpse's chest also became increasingly vivid.
Between the Patterns, there seemed to be blood flowing, and as the blood moved, the sound grew louder, like a peculiar pulse.
The redder the Patterns, the heavier the Iron Corpse's savage aura, and the stronger its struggle became.
Bai Zisheng frowned and said,
"Step back, I can't suppress it any longer!"
Bai Zixi quickly moved back gracefully with light steps.
Mo Hua also stepped back a few paces.
