The grand battle between the Human and Demon races, initially magnificent and imposing, saw soldiers facing soldiers and generals facing generals in fierce combat.
However, during the battle between the Nascent Soul cultivators, the Human race successfully slew two Demon Nascent Soul experts, causing the remaining four Demon powerhouses to flee once more.
Deprived of their Nascent Soul leaders, the Demon army crumbled like a mountain collapsing, quickly routed by the Human forces.
As the Demon army scattered, they discovered that the outskirts of the battlefield were densely packed with vengeful spirits, blocking their escape routes.
Upon learning of the impending decisive battle between the Human and Demon races, Xiao Lan had long since mobilized his subordinate vengeful spirits, who had quietly ambushed the battlefield's periphery.
Although vengeful spirits differed from humans, they were all victims of the Demon race, harboring deep resentment towards them.
The ordinary Demon soldiers that followed were not as fortunate as their Nascent Soul experts. Pursued by the combined forces of the Human army and the vengeful spirits, only a handful managed to escape with their lives.
Even Nascent Soul cultivators like Zhu Yu and Huang Feifei participated in the pursuit of the Demon race.
The Human and Demon races bore an irreconcilable enmity; there was no concept of the strong bullying the weak, nor any room for humanitarian considerations.
Once captured, they were met with lethal force, leaving the enemy no chance of survival.
After three days and three nights of relentless pursuit, less than one percent of the Demon race remained on the Eastern Continent.
"Hahaha… the Eastern Continent has finally returned to our Human race!"
Ji Wudi, bare-chested, stood atop a mountain peak, gazing into the distance. A surge of exhilaration filled him, and he couldn't help but laugh out loud.
Ji Wudi's body-refining techniques were cultivated with extreme purity, even his brain possessed a significant amount of muscle, making his thought processes simple, direct, and optimistic.
Just as there were optimists in this world, there were also pessimists.
For instance, at this very moment, Zhu Yu, looking at the Eastern Continent that had been reduced to ruins, felt a wave of sorrow.
"Our world is finished. The spiritual energy is almost depleted, and our total population is less than ten million. Is there any future for us…"
Ji Wudi dismissed Zhu Yu's pessimism with disdain.
Once he learned the truth, he had come to strongly dislike people like Zhu Yu, who were handsome and relied on their looks.
In this world, besides Xiao Fei, he would yield to no one.
"What's there to fear? At least we've driven away the Demon race and reclaimed the Eastern Continent. Everything else can be rebuilt later."
Zhu Yu, in turn, looked down on Ji Wudi, who had muscles in his brain and spent his days showing off his physique with his chest bared.
"The Demon race has only had its main force annihilated. Four of their Nascent Soul experts escaped, and the passages connecting to the Demon Realm still exist in various locations.
The Demon race could return at any moment. They have the vast Demon Realm supporting them, their strength is immeasurable. What will we use to resist them then?"
"Moreover, the spiritual energy in this world is already so scarce. Future cultivators might find it difficult to even reach the Golden Core stage, let alone advance further. How can the Human race develop?"
Ji Wudi scratched his head. He couldn't immediately answer Zhu Yu's questions, but he felt a sense of defiance.
"As you said, the spiritual energy in our world has withered and turned into ruins. What use would the Demon race have in attacking such a world? Perhaps they won't come back."
Ji Wudi still held onto optimism, or perhaps a sliver of hope.
Just as the two were about to argue further, Xiao Fei and Huang Feifei, seated on the broad backs of flying fish, flew towards them.
"Let's go!"
Xiao Fei called out to the two from a distance and then flew off into the distance. Zhu Yu and Ji Wudi quickly followed, also leaping onto the backs of the flying fish.
Their current mission was to locate the Demon Sealing Wells scattered across the continent and find a way to deal with these passages, preventing the Demon race from treating the Eastern Continent like a marketplace they could enter at will.
Additionally, they intended to track down the four escaped Demon Nascent Soul cultivators, preferably to eliminate them completely.
Otherwise, these powerful individuals might emerge to cause trouble at any time, making it impossible to guard against.
The four first flew to the nearest Demon Sealing Well.
This area originally belonged to the Great Qin Kingdom but had long since been breached by the Demon race, with dense demonic energy continuously emanating from it.
"The Demon race can pollute spiritual energy into demonic energy. Do you think we have any way to convert demonic energy back into spiritual energy?"
Ji Wudi, looking at the billowing demonic energy from the Demon Sealing Well, voiced a sudden thought.
"There is indeed a type of spiritual herb that can absorb demonic energy, convert it into spiritual energy, and then release it."
Xiao Fei, having read countless books, possessed a wide array of obscure knowledge. He recalled a book that mentioned such a spiritual herb.
"Then why don't we try to leave these exits open and use the spiritual herbs to convert the demonic energy, gradually replenishing the spiritual energy of the Eastern Continent?"
Upon hearing this, Xiao Fei shook his head. He had already considered this.
"However, this type of spiritual herb is likely extinct. In the past tens of thousands of years, no trace of this spiritual medicine has been found."
The three could only sigh with regret.
Xiao Fei and Huang Feifei, both masters of formations, began to meticulously examine the ancient formations surrounding the Demon Sealing Well.
These formations were laid out by ancient Human cultivators. After countless millennia, had they not been damaged by the Demon race, they would still be functional.
Xiao Fei, looking at the residual formation runes around the Demon Sealing Well, suddenly had a bold idea.
"I believe it's better to guide than to block!"
The other three turned to look at Xiao Fei, awaiting his explanation.
"If we seal the exits, these demons, wanting to return, will undoubtedly find ways to break through again.
Especially with things like demon seeds, which are undetectable by divine sense. Even the slightest crack allows them to penetrate, making it impossible to guard against."
The three nodded in agreement. In the past, these Demon Sealing Wells were all sealed, yet the Demon race still managed to infiltrate, leading to the current disaster.
"My idea now is to keep the Demon Sealing Wells open, no longer sealing them. Instead, we will construct a cage outside the wells, one that allows entry but not exit."
"All the demons arriving from the Demon Realm will be imprisoned within this cage."
*Snap!*
Ji Wudi slapped Zhu Yu's thigh, his eyes widening in realization.
"This plan is brilliant! Only someone like Senior Brother Xiao could come up with such a magnificent strategy."
Zhu Yu slapped Ji Wudi's hand away.
"If you have something to say, say it properly! Why are you slapping my thigh!"
"Hehehe! It was just close by!"
Ji Wudi rubbed his hands.
"Your own leg is even closer!"
Huang Feifei, ignoring their bickering, took Xiao Fei's idea and elaborated on it, coming up with new insights.
"Young Master! We can also set up potent poisons and various lethal formations within this cage."
"Feifei's idea is excellent. Let's do it this way."
Ji Wudi and Zhu Yu, lacking understanding of formations, were still entangled in their squabble.
Xiao Fei, paying them no mind, continued to discuss and refine the details with Huang Feifei.
A formation cage filled with malice towards the Demon race gradually took shape through their discussion.
