Over two hundred Gu Kings from various regions gathered together, led by a law enforcement officer from the Gu Emperor City who wielded the Purification Gu. They advanced in a grand procession towards Shi Haojun.
Ever since Long Xuan learned from Long Dan that the Purification Gu could naturally counter the Plague Demon Gu, he had thoroughly researched this type of Gu insect.
The Purification Gu is not found in either the Far West or the Western Lands, and Long Xuan had little knowledge of it before.
The primary function of the Purification Gu is to cleanse everything and eliminate all negative effects.
For instance, poison is a negative effect on the human body, so the Purification Gu can be used to detoxify.
The burning effect of flames is negative to the human body, so the Purification Gu can grant immunity to fire.
Pain is also a negative effect, and the Purification Gu can likewise alleviate pain.
In short, possessing the Purification Gu almost grants immunity to most of the world’s harm, making the owner nearly invincible.
Such an ability is truly extraordinary. One could say that the Purification Gu is among the most powerful peak-grade Gu insects in this world, and there are very few who possess it.
When the Purification Gu’s purification field is activated, it can directly eliminate the impact of the mutated domain on the microorganisms in the air, restoring them to normalcy.
It can also purify the polluted waters of the Black River, making the water safe for human consumption again.
Once the purification field is activated, the mutated field of the Plague Demon Gu is almost nullified.
Even countless plague corpses, under the influence of the purification field, will have their corpse poison eradicated and will return to normal corpses, rendering Shi Haojun’s army of corpses useless.
Therefore, the Purification Gu’s ability is a natural counter to the Plague Demon Gu.
With just one Purification Gu, at least half of Shi Haojun’s combat power would be neutralized.
However, despite this, the battle to exterminate the demon was extremely challenging, with half of the forces perishing.
In the end, it is said that a mysterious woman who could control the sun suddenly entered the battlefield and launched a sneak attack on Shi Haojun.
The mysterious woman’s combat strength was terrifying. Shi Haojun was severely injured in her ambush and almost died, but he ultimately did not perish in that siege.
He managed to escape by finding a weak point in the encirclement using mind-reading, causing the entire siege to fail.
It is said that they were fortunate that the mysterious woman attacked, or else the result of that battle would have been a devastating defeat for the Gu King coalition and a victory for Shi Haojun.
Under Shi Haojun’s slaughter, most of the Gu Kings would have fallen in that battle.
The identity of the mysterious woman remains unknown. After that battle, she vanished without a trace, and no one could find any information about her.
Afterward, a second wave of Gu King reinforcements arrived, hailing from the Central Region, where experts are as numerous as clouds. Their overall strength far surpassed that of the first wave of Gu Kings.
Upon arriving in Blackstone City, a portion of these Gu Kings first spread out to use the Purification Gu to cleanse the water bodies thoroughly, eradicating the plague in this area, while the rest continued to pursue Shi Haojun.
Moreover, Gu Kings from various places continued to arrive, showing the immense resolve in this demon-extermination operation. The Gu Emperor City would not rest until Shi Haojun was completely eradicated.
All factions planned to take advantage of Shi Haojun’s serious injuries to eliminate him. After all, the Plague Demon Gu’s growth requires constant massacres. If the Plague Demon Gu were to fully mature, who knows how many cities it would massacre, and who could guarantee that it wouldn’t be their own city next? Ꞧ
Therefore, none of the factions involved in the siege dared to slack off.
What happened next, Long Xuan did not know for the time being. The distance was too great, and news had not yet reached him.
This madman doesn’t need to conduct any experiments to research Gu Recipe. Even a single material is enough for him.
Looking at the heaven-defying spirit insect in his palm, Long Xuan's eyes flashed with excitement.
The medicinal insect ranks tenth among the Ten Supreme Spirit Insects, and its heaven-defying ability is to accelerate the growth of spiritual herbs, breaking their lifespan limits and allowing any spiritual herb to mature into a ten-thousand-year-old herb.
In other words, whoever possesses the medicinal insect can not only obtain ten-thousand-year-old spiritual herbs in bulk but can also obtain peak-grade spirit insects in bulk.
If a herb garden could frequently produce thousand-year-old or ten-thousand-year-old spiritual herbs, and it was filled with peak-grade spirit insects, even a pig could stand at the pinnacle of the world with such vast wealth!
Moreover, this heaven-defying ability ranks only tenth among the Ten Supreme Spirit Insects. How terrifying must the first nine be?
Long Xuan's breath quickened. This medicinal insect was truly a timely rain, providing him with enormous help.
It should be known that the four Divine Dragon's Wood seedlings in his herb garden are still in their infancy, producing a limited amount of Divine Dragon's Milk Sap. Who knows how many years it would take for the Eye of Heavenly Secret to complete its perfect evolution?
But now he doesn’t have to worry about that anymore.
The medicinal insect can rapidly mature the Divine Dragon's Wood. The Eye of Heavenly Secret evolution is not far off.
No, to be precise, the medicinal Gu can rapidly mature the Divine Dragon's Wood. He has the ability to refine the medicinal insect into a medicinal Gu, making the heaven-defying spirit insect even more heaven-defying.
Thinking of this, Long Xuan felt even more excited. He couldn't wait to quickly develop the medicinal Gu recipe. He couldn't wait any longer.
He immediately ran home, ready to go into seclusion for some time. He had no intention of continuing to guard this place.
However, what Long Xuan didn't know was that just as he left, a weary-looking woman emerged from the formation. She looked in the direction where Long Xuan had left, let out a long breath, and said, "He’s finally gone, huh?"
She suddenly revealed a charming smile, opened her insect pouch, and released a Blade Gu.
That’s right, she had successfully refined the Blade Gu with tens of thousands of materials. She truly was a child of fortune, successfully refining a ten-thousand-level Blade Gu with just one attempt.
If Long Xuan had been present, he would have exclaimed again, "A child of fortune!"
With a ten-thousand-level Blade Gu, she could sweep through this region.
Of course, no matter how extraordinary she was, she couldn't compare to Long Xuan. Long Xuan had fifty-three thousand materials for his Blade Gu, while her tens of thousands of materials couldn’t even compare to a fraction of that. How could she compete?
Monsters always fear meeting other monsters; otherwise, you'd discover that there’s always a more terrifying one.
"Can't wait, huh? I no longer intend to have you take the fusion spirit weapon evolution route. I want you to take the more difficult sword intent evolution route. Your master now has the strength to make that happen," Long Ziyan said confidently, stroking the Blade Gu's head with a smile.
She suddenly pointed her fingertip at the Blade Gu's forehead, and a powerful sword intent, radiating cold energy, surged into its mind, causing its eyes to turn dull in an instant.
"Comprehend this well. This is the sword intent you need to understand for your first evolution, and it is also my strongest sword intent. As long as you comprehend this sword intent, you will have successfully transformed."
Long Ziyan patted its head again, then turned around with a smile and left.
Having spent a lot of time with Long Xuan, she had gradually picked up some of his habits. One of them was the habit of always patting Gu insects on the head.
The Blade Gu, feeling the sword intent in its mind, slowly showed a look of excitement. It then eagerly sat down and began to close its eyes, meditating on the Ice Sword Intent.
Thus, the place fell silent once more...
