At this moment, Zheng Yi noticed that the red clothes on the Red-clothed Female Ghost were not originally red. From the style, it vaguely appeared to be a school uniform.
Yet the color was dyed red with fresh blood. It's hard to imagine how many people she must have killed to turn it red.
Rip! Rip...
The Red-clothed Female Ghost was quickly tearing at the Black Evil Qi surging from the Soul-Catching Banner. She seemed to know that as long as she ripped through the Black Evil Qi's defense, the culprit hiding inside would have nowhere to hide.
Watching the ferocious Red-clothed Female Ghost, Zheng Yi was not surprised. With a reverse flick of the Soul-Catching Banner, powerful and tall Fierce Ghosts emerged from the surging Evil Qi, eighteen or nineteen of them, all were the gains from the past few days.
As the Soul-Catching Banner pointed, they roared and pounced toward the Red-clothed Female Ghost.
It was a one against nineteen battle. Despite the absolute disadvantage in numbers, the Red-clothed Female Ghost fought the Fierce Ghosts to a standstill.
It's important to know that the Fierce Ghosts within the Soul-Catching Banner were chosen selectively and only those who survived after mutually devouring each other remained. They were far stronger than those ordinary Fierce Ghosts appearing in the school.
Yet in facing the Red-clothed Female Ghost now, even with their combined effort, they were absolutely at a disadvantage. Instead, she would sometimes burst out and heavily injure the Fierce Ghosts within the Soul-Catching Banner.
At this time, Zheng Yi couldn't help but wave the Soul-Catching Banner, accurately directing a wave of Black Evil Qi onto the injured Fierce Ghosts, whose broken bodies directly restored to their original state.
Soon after, they rejoined the battle against the Red-clothed Female Ghost.
This was outright cheating. One side kept healing and restoring, making it impossible for the Red-clothed Female Ghost to defeat these Fierce Ghosts.
"Still trying to escape now? Unfortunately, the chance is gone."
After a full hour of battle, just as the Red-clothed Female Ghost was exhausted, blasting away a Fierce Ghost in front and letting out a sharp ghostly scream, ready to escape,
Zheng Yi waved the Soul-Catching Banner, causing several Fierce Ghosts that were originally behind to vanish instantly, only to reappear in front of the Red-clothed Female Ghost.
This was the trap he prepared for the Red-clothed Female Ghost, the King of Hundred Ghosts in this Ghost School, ensuring that once within the range covered by the Soul-Catching Banner, she wouldn't leave.
Under the siege of more than a dozen Fierce Ghosts, the Red-clothed Female Ghost was eventually exhausted and subdued by the Fierce Ghosts, thrown into the Soul-Catching Banner.
In any case, Zheng Yi knew his strength was weak, and he would never take risks to act personally, well versed in the art of survival.
The Soul-Catching Banner itself could manipulate Fierce Ghosts and Resentful Spirits to attack, so why bother taking action himself.
This doomsday world for a demon cultivator is an inexhaustible treasure trove.
He didn't mind temporary gains or losses.
Fortunately, after planning, everything turned out as desired.
Instantly, after subduing the Red-clothed Female Ghost, the King of Hundred Ghosts, Zheng Yi immediately felt a surge of Evil Qi pouring out from the Soul-Catching Banner, integrating into his body.
The aura of Black Evil Technique within him surged upward slightly; he gained significant benefits.
After refining the Red-clothed Female Ghost, it seemed there were no more formidable ghosts in the school, so Zheng Yi continued refining the Soul-Catching Banner, persisting for about ten days.
Ultimately, after refining forty-nine Fierce Ghosts within the Soul-Catching Banner, Zheng Yi gave up on this place.
"Spending ten days to refine forty-nine Fierce Ghosts is already the limit of the Soul-Catching Banner."
Zheng Yi thought to himself, somewhat distressed.
Refining forty-nine Fierce Ghosts in one go, the Soul-Catching Banner had reached its limit, and the time used was indeed minimal, even less than what Zheng Yi had imagined before.
It's evident how abundant the cultivation resources are in this doomsday world for demon cultivators.
But even so, once the Soul-Catching Banner is activated, even a cultivator at the Qi Cultivation Seventh Layer might not withstand the attack of forty-eight Fierce Ghosts led by the Red-clothed Female Ghost.
Of course, this limit is just the limit of the Soul-Catching Banner in Zheng Yi's possession.
Above it, there's a magical artifact called the Hundred Souls Banner, which can refine a hundred Fierce Ghosts.
According to the introduction in the Soul Catching Sect's cultivation technique, if the Seven-Faced Hundred Souls Banner forms an array, its power could even match that of a great cultivator at the Early Stage of Foundation Establishment.
Zheng Yi waved the Soul-Catching Banner.
With a piercing banshee's wail, amidst the whistling yin wind, the Spiritual Power within his body poured in madly. A burst of black fog surged on the Soul-Catching Banner, directly engulfing the surrounding area of more than ten square meters.
In the black fog, bursts of sinister and terrifying roars were heard; vague figures of grotesque demons began to emerge.
When the black fog thinned, Zheng Yi held the large black banner aloft, with the bronze staff gripped in his palm, the large black banner fluttered in the wind, revealing the form of forty-nine skulls on its surface.
At the same time, amidst the mist, around the perimeter of Zheng Yi's body, appeared the images of forty-nine grim Fierce Ghosts.
These Fierce Ghosts were all the victors from within the Soul-Catching Banner, where numerous resentful spirits devoured each other. Their ghost Qi was rich, each one's surface seemingly layered with a substance as black and slick as oil.
That was the Evil Qi, so dense that it resembled a tangible presence.
As a Demon Dao Sect specialized in manipulating souls and ghosts, the Soul Catching Sect managed to secure a foothold in the Demon Realm, naturally boasting its own unique Secret Techniques and distinctions.
Especially in refining Fierce Ghosts and Resentful Spirits, they had reached an extraordinary level, far exceeding many sects of higher status than the Soul Catching Sect, particularly in the aspect of Soul Capturing and Ghost Control magic.
This is one of the reasons Zheng Yi, after much consideration, ultimately chose to join the Soul Catching Sect.
He only had the cultivation level of Qi Cultivation Third Layer, with not many methods to confront enemies besides a Fine Steel Flying Sword in hand.
If the zombie crowd contained Red-eyed Zombies, they posed a significant threat.
However, there were not as many issues regarding Ghost-Controlling Skills.
The Soul-Catching Banner from the Soul Catching Sect was the Celestial Overlord against those Resentful Ghosts and Fierce Ghosts.
Even when encountering those old ghosts with a century of Dao Practice, relying on the Soul-Catching Banner's ability to suppress soul bodies,
Zheng Yi, even if unable to win, could at least escape, maintaining a degree of flexibility.
And the Soul-Catching Banner he now held was merely the lowest level, a mass-produced standard product for outer disciples recruited by the Soul Catching Sect. Though its appearance was crude, it was simple to use,
Perfectly suitable for his current use.
After all, the Soul-Catching Banner, as a composite-type magical artifact, unlike ordinary magical artifacts, could be upgraded and iterated.
The Soul-Catching Banner is primarily composed of two parts.
The Soul-Catching Stick of the banner's rod part and the Soul Refining Cloth on the banner's surface.
Once he had the funds or his cultivation improved,
The bronze Soul-Catching Stick could be replaced with a White Bone Staff, the ordinary Soul Refining Cloth could also be updated to be woven with Soul Spider Silk into a Five Yin Cloth or knitted with Ice Silk into a Thousand-Section Brocade.
If he could even acquire the refining method of the Soul-Catching Banner or an upgraded Refining Technique, that would be even better, allowing him to refine, upgrade, and iterate on his own.
The interior of the entire Soul-Catching Banner forms a massive Yin Soul Space, akin to the vessel for Gu Cultivation in the Five Poison Sect.
It's not simply about collecting grudging ghostly creatures inside, but also letting them battle and devour one another to become increasingly fierce, ultimately emerging as stronger Fierce Ghosts.
This is the core aspect of the Soul-Catching Banner.
