I Was Forced to Become the Demon King's Succubus Lover - Chapter 1

Torrential rain poured down, lightning flashed, and thunder roared. A dense black mist enveloped the city-state, spreading an oppressive atmosphere across the land.

High in the sky, a golden light and a dark light clashed intermittently, their collisions accompanied by deafening booms and waves of scorching heat that washed over everyone’s faces.

All eyes were fixed upward, staring in stunned disbelief.

The Demon King and the Saint were fighting.

The Demon King and the Saint were truly engaged in battle, and they seemed evenly matched.

Could the Saint really hold his own against the Demon King?

As if just awakening from this epoch-defining struggle, or perhaps realizing for the first time that freedom might be within reach, the people trembled, their lips quivering, unable to utter a single word.

For a thousand years, countless generations of Saints had challenged the Demon King, yet it seemed only this one.

They dared not dwell on the thought, fearing that greater hope would lead to greater disappointment. Yet, deep in their hearts, a glimmer of anticipation inevitably began to rise.

What if… what if this Saint truly defeated the Demon King? What if… what if they could finally attain freedom?

This was the first time they had ever been so close to victory and liberation.

Finally, someone spoke up, their voice faltering.

“O great God of Light, your most faithful devotees offer everything in prayer. May our Saint defeat the evil Demon King.”

No matter what, they wanted to offer their most sincere prayers for this Saint, even though, should he lose, the Demon King’s retribution might leave them with no place to rest in death.

For a moment, across the city-state, whether mages, elves, dwarves, or commoners, all prayed fervently. They prayed for Saint Norton Similias to triumph over the Demon King and slay the ruler of the abyss.

High above in the black mist-shrouded sky, the golden light suddenly came to a halt.

“Saint, I must say, I’m surprised you’ve lasted this long.”

Not far away, a handsome man dressed in a black tailcoat, appearing remarkably refined and courteous, wore an indifferent expression as he glanced at his opponent. Then, with a flick of his finger, he conjured a speck of light no larger than a grain of rice.

As the speck appeared, the people below paled in terror. It radiated an aura of evil and bone-chilling cold unique to the abyss, darker and more sinister than any other dark energy. Some of the weaker commoners were already covered in a layer of terrifying frost.

Panicked cries rang out: “Quick, quick! Set up defensive magic!”

The mages below waved their wands, casting magic circles to ward off the icy onslaught. Yet their efforts were like trying to extinguish a fire with a cup of water, utterly insufficient. Many were frozen into ice sculptures.

The Demon King, Li Xier, glanced down and let out a disdainful scoff.

The weak would always be weak.

The speck of light was flicked away. Li Xier’s face turned pale, but everyone’s attention was fixed on the speck as it shot toward Su Sheng like a bullet.

“Well then, it’s time to end this game.”

A cold wind whipped at Li Xier’s tailcoat, causing it to flutter and snap violently in the air.

Su Sheng stared coldly at his opponent. Li Xier’s smile was so casual, as if he had already foreseen the outcome.

The people of the city-state sensed the immense power contained within the speck of light and held their breaths. Some even shut their eyes in despair.

Carrying a cold capable of freezing through anything in this world, the speck of light shot forward with incredible speed. Su Sheng did not retreat an inch. Bathed in a golden glow, he raised his holy sword without hesitation and swung it forward.

The clash of light and holy sword sent Su Sheng staggering back several steps from the tremendous impact.

His internal organs churned violently. Su Sheng turned his head and spat out a mouthful of blood. The shockwaves caused blood to seep from his eyes, nose, and ears, and even the hand gripping his sword trembled uncontrollably.

Yet he still refused to give up.

The Demon King paused, seemingly surprised that his attack had been blocked this time. A flicker passed through his gaze as he withdrew his casual smile and asked in a nonchalant tone, “Are you this generation’s Saint? What is your name?”

Su Sheng remained silent, his expression indifferent. He simply stared at the Demon King’s paling complexion, gathering magic while the other spoke.

Golden points of light coalesced into a sea of radiance in mid-air, converging upon the holy sword before pressing down upon the Demon King with lightning speed.

Logically, that strike alone shouldn’t have been enough to kill the Demon King. It was the Demon King himself who chose not to dodge.

He endured the blow head-on. Golden blood flowed down the blade onto Su Sheng’s hand, scalding him enough to make him flinch.

Then, step by step, the Demon King advanced toward Su Sheng without the slightest hesitation, allowing Su Sheng’s sword to sink deeper as he drew closer.

Finally, Li Xier came to a halt before Su Sheng. They stood so close that Su Sheng could even feel Li Xier’s breath.

“You do have some skill,” the Demon King Li Xier said.

As he moved, a drop of golden blood fell onto Su Sheng’s eye. Su Sheng instinctively closed it, and the blood slid down his eyelid to the corner of his eye, like dye staining a white cloth.

Suddenly, the Demon King raised his hand.

Su Sheng tensed, preparing to defend himself, but then abruptly stopped. Unexpectedly, the Demon King merely lifted his hand, his fingertip tracing along Su Sheng’s jaw before pausing on the vulnerable Adam’s apple. Then, he cupped Su Sheng’s face, using his thumb to wipe away that drop of golden blood, his tone disdainful: “Killing me, you will regret it, especially you.”

With those words, the Demon King’s body dissolved into motes of light, scattering into the air.

Su Sheng coldly lowered his hand. Immediately after, a beam of holy light descended upon the sacred altar, followed by a second, then a third…

Below the altar, the cheers of humans, dwarves, elves, all races belonging to the light, resounded endlessly.

During the ceremony for the new Saint, the pristine white marble pillars gleamed as if freshly polished. The steps beneath the sacred altar, carved with the emblem of the God of Light’s flower, were lavishly decorated on both sides. Dressed in white robes and holding a staff as tall as himself, Su Sheng ascended barefoot.

The priest held a scroll, followed by members of the Royal Guard and the Temple Knights, all bowing to Su Sheng.

By tradition, after such a monumental event, the human Saint of this generation slaying the Demon King, everyone was expected to kiss the Saint’s hand as a sign of respect.

Taking advantage of the chaotic crowd, Su Sheng cast a duplication spell on himself and pulled the Holy Knight Commander, Fei Meng, aside into a corner.

“Norton, oh, no, Your Holiness, you are truly magnificent…”

“Stop, Fei Meng.” Su Sheng rubbed his temples, cutting off what Fei Meng was about to say. “I didn’t come to hear that. I’m leaving.”

“Oh, my God, my great God of Light, I know you’re leaving, but why must you go now? The people still need you.”

Su Sheng could sense that the moment he uttered the word “leave,” his friend before him stiffened, and his tone turned oddly strange.

But he didn’t care, nor did he bother to explain everything. He believed his good friend could handle everything here in his stead, for they were cousins after all.

And he had far more important matters to attend to.

“Fei Meng, listen.” Su Sheng frowned, gripping Fei Meng’s hand tightly. “I have something very important to do right now. I’ll cast a transformation spell on you, just like when we were kids. You’ll have three days to prepare everything. After three days, you will succeed me as the Saint and the throne.”

You will succeed me as the Saint… and the throne… you will…

It took Fei Meng a moment to process what Su Sheng had said, and his eyes widened instantly, his expression turning horrified. “Are you joking, Norton?”

Fei Meng knew Su Sheng had never cared much about these things, but handing over the position of Saint and the throne to someone else was simply too outrageous.

Su Sheng watched Fei Meng calmly, observing as his friend gradually regained his composure and stood properly once more.

He saw Fei Meng’s limbs moving awkwardly, clearly overwhelmed by the sheer magnitude of the information, yet still struggling to find a way to respond.

“Alright, I mean… my magical affinity isn’t as strong as yours, and besides, I don’t have the light element. How could I possibly succeed you as the Saint?”

Fei Meng clearly disagreed with Su Sheng’s reasoning, but he seemed afraid that his agitation might draw attention. Nervously, he glanced around.

“I’ve cast a barrier spell. No one can hear our conversation here.” Su Sheng saw through Fei Meng’s actions.

“But…”

Fei Meng wanted to say more, but Su Sheng cut him off.

“Don’t worry, I have a solution.” Su Sheng had anticipated Fei Meng’s concerns and pulled out a vial of light magic potion he had prepared earlier, handing it over. “One bottle of this will temporarily grant you the same light element affinity as me. I’ve prepared an entire box, hidden in the study of the temple. You know where it is.”

Su Sheng’s way of handling matters was as decisive and detached as he was. Feeling he had explained everything necessary, he ignored Fei Meng’s reaction and prepared to cast a spell to leave. Unexpectedly, Fei Meng grabbed his arm, his head lowered, his expression hidden in shadow:

“Can you tell me what you’re going to do?”

“Find someone.”

Su Sheng slowly pried his friend’s hand away, his expression turning cold.

In this world, he was Norton Similias, the heir to the most prosperous kingdom on the continent and the seventy-second Saint chosen by the light-aligned races. But no one knew that he was actually Transmigrator No. 001, sent to this world to carry out a special mission.

And this mission was so unique that he had come alone this time, without his bound system.

Watching Su Sheng’s expression, Fei Meng’s face shifted through several emotions before finally settling into resignation. He opened his mouth, then slowly stepped back. “Alright, go quickly and come back soon.”

“Mm.”

As soon as the words fell, Su Sheng cast a teleportation spell and appeared outside the city.

He walked into a shabby, rundown inn on the outskirts. The inn was quiet and empty, as nearly everyone from the nearby main city had gone to attend the Saint’s succession ceremony. Su Sheng wasn’t worried at all about being recognized.

He made his way with practiced ease to the door at the very bottom of the stairwell. There, he removed the white robe that symbolized his identity as the Saint. In the mirror nearby, a young man with black hair and dark eyes was reflected, his features more exquisite than those of an angel.

The young man’s slender figure was concealed beneath a lake-blue mage’s robe, his fair skin once again hidden beneath the garment. A soft, smooth black hat, matching the color and style of the robe, was gently placed atop his head.

Once dressed in this manner, Su Sheng left the inn. He took out an instrument that did not belong to this world, which displayed all the characteristics of his mission target.

He held three things in his hands: name, power, and justice.

This meant he had to visit everyone who possessed these three things.

Those who possessed all three were not many, but certainly not few. Fortunately, he still had enough time to visit them one by one.

Su Sheng compiled a sufficiently long list containing the names of all those who possessed these three things, and now he was about to visit the first one.

Along the way, with the retreat of the dark aura, he encountered no demons. Yet, Su Sheng couldn’t help but tug on the reins, bringing his horse to a halt as he surveyed his surroundings.

He was traveling along the main road, yet not a single person was in sight. A sense of unease crept over him, and he raised his hand to cast a small detection magic circle, but it yielded no results.

Recalling the joyful faces of the people before his departure and the meaningful words spoken by the Demon King on his deathbed, Su Sheng remained unsettled. After a moment, he turned his horse around and headed back toward the kingdom.

Upon re-entering the city, he found every household shut tight, the once vibrant atmosphere completely gone. Even the occasional vagrant or bard on the streets turned their backs to the road, refusing to utter a single word.

Su Sheng frowned, finding the scene utterly eerie. It seemed as though something terrible had already happened. An inexplicable sense of crisis gripped him, and he tightened the reins, urging his horse swiftly toward the temple.

Before the sacred altar, everything appeared as usual. Even the flowers from the succession ceremony still adorned the steps on either side, though they had been scattered by the wind, with no one bothering to tidy them up.

Hadn’t he only been gone for half a day? How had the sacred altar become so…

“Desolate”?

Su Sheng first dismounted and removed his disguise, then walked through the sacred altar and into the temple.

The temple guards, upon seeing Su Sheng, shifted from expressions of distress to overwhelming joy, and finally to reproach.

“Your Holiness, why have you only just returned?”

“What happened?” Su Sheng glanced outside, removing his outer robe and handing it to the approaching maid. He then noticed the crowd of people hiding inside the temple swarming toward him.

He scanned the group, somewhat surprised to find that the temple had taken in some outsiders and vagrants.

“We… we don’t know either. It’s like some strange game.”

“No, you’re wrong. It’s not like a game, it’s more like a curse!”

“Oh, heavens! A curse? Could it be that the evil Demon King cursed us before he died?”

As everyone chattered, a faint cough suddenly sounded, and the crowd parted to make way.

The High Priest, leaning on a cane, appeared, supported by Fei Meng, who was using his original face. Clearly, the deception had been uncovered by everyone.

But no one mentioned it. Instead, they were all discussing the series of strange events that had occurred over the past few hours.

“The white doves suddenly flew away, every single one of them.”

“Mrs. Ji Nuo from Rainbow Avenue suddenly disappeared before and has been talking nonsense ever since she returned, saying things like ‘the Demon King’s punishment is coming, the Demon King will descend again’ and such.”

The words sounded absurd, after all, the Demon King had clearly been killed by him, but recalling the Demon King’s last words…

Su Sheng pursed his lips tightly, his expression grim, and asked, “Besides that, what else happened?”

At this question, everyone fell silent. After a moment, the elderly voice of the High Priest finally replied:

“Do you remember the small inn outside the city?”

Seeing Su Sheng nod, the High Priest continued:

“The innkeeper there was killed by a demon, and his body was devoured by vulture demons.”

Su Sheng’s heart jolted with shock. He furrowed his brow, he had been at that very inn at the time. How had he not noticed? Just as he was about to speak, a thick black fog enveloped the kingdom, and a magnetic, captivating yet bone-chilling voice echoed through the air.

This voice belonged to none other than the Demon King who had appeared in the sky half a day earlier, only to be slain by the Saint with a single strike of his sword.

“Ignorant commoners, you have provoked the Demon King. To appease the wrath of the Dark God, you shall now be cursed with the most malevolent fate, to be transformed into the lowest form of demons for all eternity.”

As soon as the words fell, the crowd froze as if time had stopped, disbelief etched on every face.

Someone murmured, “But the Demon King is already dead, isn’t he?”

Then, as realization dawned, chaos erupted. Some crouched in terror, clutching their heads and praying to the God of Light; others stood dazed, their legs trembling so violently they could barely walk.

People flooded into the temple, pushing and shoving until the scene descended into utter pandemonium.

At the same time, the horrified crowd watched in terror as their own bodies began to change.

Some grew serpent-like tails, others sprouted thick horns on their foreheads, and even more horrifying, many found their lower bodies transforming into the legs of deer or horses, the tails of snakes, or other bizarre appendages.

Only Su Sheng remained in his human form.

The scene was surreal and grotesque, like a gentle angel surrounded by a panicked horde of demons.

When those who had transformed into demons noticed that their Saint still retained his human appearance, they surged toward him in desperation. Even the usually composed and steady High Priest trembled with fear, his voice shaking:

“Norton, save your teacher.”

Those who could still speak pleaded desperately, “Your Holiness, help us, please help us!”

“We don’t want to become demons, we don’t want to turn into demons!”

…

Su Sheng was pushed out of the temple by the crowd onto the sacred platform, then cornered at the edge, nearly falling off before the quick-witted Fei Meng pulled him to safety.

Fei Meng dragged Su Sheng behind the temple doors.

Fei Meng complained, “Why didn’t you use magic to keep those people away? Do you realize you almost fell just now?”

“I don’t want to use magic on my own kind,” Su Sheng replied with a frown, unwilling to elaborate. Seeing Fei Meng about to continue his lecture, he cut him off, “Let’s not dwell on that now. Go and gather the other citizens of the city-state. Tell them I have a solution.”

Fei Meng hesitated, swallowing hard before finally asking, “Norton, why has the Demon King returned?”

Su Sheng furrowed his brow and shook his head. “I’m not sure either, but if you don’t want to fully demonize, you’d better go quickly.”

Fei Meng was about to leave when he suddenly seemed to remember something, his expression turning serious. “By the way, have you heard about the rumor that’s been spreading lately?”

“What rumor?” Su Sheng was taken aback, instinctively looking at Fei Meng.

Fei Meng said, “People are all discussing a ‘Three-Day Pact.’ The content of the phrase is…”

He paused, then slowly recited, “The King of the Abyss is not dead. Everyone will vanish under the first ray of sunlight on the third day.”

Su Sheng tightened his grip on his staff until his knuckles turned white, a cold glint flashing in his eyes. He said slowly, “This is a conspiracy… What is the public’s reaction? Do we know the origin of this phrase?”

Fei Meng hesitated before replying, “Most people believe it. As for the origin, I’ve already sent people to investigate.”

After a moment of silence, Su Sheng took a deep breath. “Alright, I understand. You should go now.”

“Then I’ll leave. Take care of yourself.” Fei Meng wasted no more time. He patted Su Sheng’s hand three times, a secret signal they used as children when gathering. By now, his lower body had already transformed into hooves, allowing him to run swiftly.

There was no curse inflicted upon the human body that could not be broken by a potion. Su Sheng used teleportation magic to arrive at the potion room. After washing his hands, he sat at a table covered with glass bottles and began to brew.

For the sake of the kingdom’s people, he would surely concoct the potion he needed.

At the same time, a massive eye opened in the sky. Its black pupil seemed to contain all forms of evil, and the direction it stared at was unmistakably where Su Sheng was.

Su Sheng, however, was lowering his head, testing the toxicity of a newly brewed potion. As blood flowed from the cut made by the knife, the pupil in the sky suddenly contracted.

In the abyss, upon a throne adorned with gold, silver, and jewels, a pair of demonic wings slowly unfurled. A handsome man with a pair of demonic horns atop his head opened his eyes. As his brows relaxed, a trace of disdain inadvertently surfaced.

“The one who killed my avatar walking in the mortal realm… is the new Saint, I presume?”

“Nothing more than an ant.”
