As for the Fierce Ghost that was torn apart, since its essence had long been integrated into the Soul-Catching Banner, it belonged to the undying and immortal.
Unless one has the great power to instantly obliterate its spiritual imprint, or the Soul-Catching Banner is utterly destroyed, wanting to simply kill the Fierce Ghost is simply impossible.
Zheng Yi waved the Soul-Catching Banner, and black mist continuously gathered. The Fierce Ghost that was eliminated appeared again, with only a slightly weaker aura, but no other significant changes.
The Red-clothed Female Ghost, who was blocking the Cyan Ghost's escape, was directly covered by a black fog, restoring her body to its original state.
This is the power of the Soul-Catching Banner once refined into a Lifebound Spiritual Artifact, complemented by the "Black Evil Technique" as the foundation. The released Fierce Ghosts are undying and powerful.
Even when facing a more powerful special form of the Hundred-Year-Old Cyan Ghost, there is no fear at all.
Instead, gradually, it turned into a war of attrition, eventually leading to the Soul-Catching Banner's Fierce Ghosts gaining the upper hand.
In fact, this Hundred-Year-Old Cyan Ghost is already considered a powerful ghost entity. Its special form, strength, and speed are all unique energy feedback.
Although far inferior to the Bloodthirsty Evil Ghost in grade, this Hundred-Year-Old Cyan Ghost can already be considered at the level of a Half-step Ghost General, equivalent to a cultivator at the Sixth Level of Cultivation in the Great Yi City Immortal Realm.
Unfortunately, these three old ghosts have never cultivated the Ghost Dao Secret Technique, unable to directly convert a hundred years of Dao practice. Otherwise, in the Cultivation Realm, an old ghost with such Dao practice might have the opportunity to become a Ghost King, provided they could bide their time!
Of course, the premise is not to be easily slain by those Righteous Disciples or enslaved by a Demon Cultivation Sect like the Soul Catching Sect.
If Zheng Yi were to face these three Hundred-Year-Old Cyan Ghosts alone, he would be devoured with not even scraps left.
However, precisely because he held the Lifebound Spiritual Artifact, the Soul-Catching Banner, which was a Celestial Overlord against various ghost entities and resentful spirits.
With only a Qi Cultivation Fourth Layer, Zheng Yi managed to corner the three Hundred-Year-Old Cyan Ghosts, making them like caged beasts, trapped in a stalemate battle.
The battle between ghost entities continued. Even though the Hundred-Year-Old Cyan Ghost had a strength advantage, it could never threaten the caster, Zheng Yi, from start to finish.
Instead, as time passed, with the support of the Soul-Catching Banner, the Red-clothed Female Ghost leading forty-eight Fierce Ghosts began to gain the upper hand.
By taking advantage of their formation, the Fierce Ghosts within the Soul-Catching Banner firmly controlled the movements of the three Cyan Ghosts.
In each clash, the strength of these three centennial old ghosts was greatly weakened.
On the side of the Fierce Ghosts, with the assistance of Zheng Yi, who controlled the Soul-Catching Banner, and the replenishment of the "Black Evil Technique," the Cyan Ghost's advantage was greatly diminished.
From initially gaining the upper hand to balancing the factions, eventually, the three Cyan Ghosts became anxious. While not highly intelligent, they could clearly sense they were in a dangerous situation.
"Screech!"
The Red-clothed Female Ghost seized the moment, seeing one of the Hundred-Year-Old Cyan Ghosts frantically defending against the attacks from multiple Soul-Catching Banner Fierce Ghosts wielding Black Evil Long Sabers, and finally revealing a defensive flaw.
A swath of red flew by, and a long silk gathered with intense blood-colored ghost Qi struck hard on the Cyan Ghost's chest. With such strength, it blasted the Cyan Ghost away again, dispersing the ghost Qi accumulated on it.
As the main soul of the Soul-Catching Banner, the Red-clothed Female Ghost now with heightened intelligence, would not miss this chance.
She directly controlled dozens of Fierce Ghosts from the Soul-Catching Banner to form a formation, swarming up, continuously hacking at the body of the Hundred-Year-Old Cyan Ghost with Black Evil Long Sabers in hand.
The Cyan Ghosts, with their immense strength and hardened body defense, have it as their special form, but faced with such frenzied attacks from so many Soul-Catching Banner Fierce Ghosts, it's impossible not to break their defenses, with their ghost bodies chopped into pieces.
Ghost entities, regardless of how special their form, are fundamentally of the Spirit Body nature. With so many parts of the ghost body cleaved, before the old ghost could re-fuse, these fragments were absorbed by Zheng Yi through the Soul-Catching Banner.
With tides turning in favor, the Soul-Catching Banner's arrogance increased.
Conversely, the centennial old ghost had large parts of its ghost body chopped off, shrinking significantly, its aura weakening, unable to maintain its previous presence.
This illustrates the might of the Soul-Catching Banner in dealing with ghost entities, not only capable of controlling the Fierce Ghosts within the banner but also wresting control of Essence Qi Energy from ghost entities.
Moreover, with Zheng Yi being a Loose Cultivator and now the master of the Soul-Catching Banner, low-cost combat is customary; how could he pass on such an opportunity?
"Screech Screech!"
This centennial old ghost, trapped like a king of beasts, exhausted but unwilling to surrender.
Though its aura greatly diminished now, desperately resisting was merely a stubborn struggle. Instincts drove it to use every means possible, attempting to escape the perilous besiegement.
It constantly vibrated the remaining ghost Qi around it, repeatedly blasting surrounding Soul-Catching Banner Fierce Ghosts away, but quickly became entangled by the Soul-Catching Banner's main soul, the Red-clothed Female Ghost, with other dispersed Fierce Ghosts swarming back again.
After several iterations, the Cyan Ghost's strength severely dwindled, unable to hold any longer, the Red-clothed Female Ghost's long silk whipped out, and the Cyan Ghost shattered into pieces amid explosions.
Ghost Qi reformed, and the Cyan Ghost's figure reappeared.
But now its aura was less than half of its prime, no longer shrouded in the surging ghost Qi, although still fiercely intimidating, incapable of killing even a Soul-Catching Banner Fierce Ghost in the short term.
"Capture it!"
To Zheng Yi's command of controlling the Soul-Catching Banner, as the main soul within the banner, the Red-clothed Female Ghost had not a hint of resistance or capability; the blood-red long silk she held flew through the air, directly piercing through the Cyan Ghost's legs, binding the ghost entity.
Being Spirit Bodies, typically formless and incorporeal, ordinary weapons cannot harm them, but the Fierce Ghosts within the Soul-Catching Banner perfectly counter this, preventing even the chance for it to scatter and escape.
With its legs bound, unable to move, the Cyan Ghost's combat strength dropped sharply again. Before the Cyan Ghost could react, numerous Soul-Catching Banner Fierce Ghosts swarmed in, hacking it to death with blades.
Once its form reappeared with even more weakened aura, it was directly controlled, the Red Silk coiled up, completely binding the Cyan Ghost and sending it into the Soul-Catching Banner.
As a unique Magical Artifact for manipulating and controlling ghosts, the Soul-Catching Banner is a Celestial Overlord against ghost entities, not only a Magical Artifact for refining Resentful Ghosts and Fierce Ghosts but also possesses the ability to trap and suppress ghost entities.
Especially after Zheng Yi refined this banner into a Lifebound Spiritual Artifact, such properties became even more potent.
With a thought, Zheng Yi created a separate Yin Qi Space within the Soul-Catching Banner, suppressing the captured Cyan Ghost inside.
With the first Cyan Ghost dealt with, naturally, a batch of idle Soul-Catching Banner Fierce Ghosts became available. Zheng Yi manipulated them to join the assault on the remaining two Cyan Ghosts.
Originally, the Cyan Ghosts' combat strength was significantly restrained within the domain of the Soul-Catching Banner. Now, with more Fierce Ghosts besieging the two Hundred-Year-Old Cyan Ghosts, and the Soul-Catching Banner's main soul, the Red-clothed Female Ghost eyeing them closely, it was even worse.
Without using much effort, the remaining Soul-Catching Banner Fierce Ghosts swarmed, immediately slaying the two remaining Cyan Ghosts into a weakened state.
One by one, they were collected by Zheng Yi into the Soul-Catching Banner and suppressed.
