After I died, my personal maid rebelled.

They are always more concerned than the Demon King himself about who the Demon King will choose as his successor.

Is it the eldest prince, the second prince, the third prince, or the eighth prince, the thirteenth prince, and the fourth prince who seems to be on the fringes but is actually highly valued by His Majesty the Demon King?

Alas, the Demon Kingdom has been too deeply influenced by humans.

In the past, it would have been so simple: just throw all the princes into the dueling arena, and the one who survived would be the heir.

Now... the previous human king, Frank, has once again set an example and model for the princes. The royal city and the royal palace are perfect places to carry out underhanded tactics.

Frank: Remember, it's all about cunning. Only the city's army truly counts as an army—the royal guard, the royal guard, private armies, and assassins can all be manipulated covertly. The army is the first step; controlling the city gates and the armory is the second…

The princes: We've learned our lesson. From now on, we'd rather die than leave the Demon King's castle.

His Majesty the Demon King is pleased to see the competition among the demons below, even if these demons are his own children.

Otherwise, he wouldn't have chosen a princess like Vivian to lead foreign campaigns instead of a bunch of valiant princes, and even went to comfort his daughter after a defeat.

As for the princess's good brothers, their fake greetings were just a way to keep her dealing with the troubles outside, so that she wouldn't be squeezed out of the Demon King's castle and become the first to be eliminated!

Strength reigns supreme? Power reigns supreme! To expect a race with intelligence to yield to so-called talent and real ability is nothing short of a fantasy.

General Colin was frustrated by being unfairly blamed, but what frustrated him even more was not the power struggles in the Demon King's Castle, but the steady development of his rivals.

Charles and his sister from the Northern Territory, despite their small family size, each member is an exceptional hero.

Perhaps in just a few years, the balance of power between the human and demon races will undergo a dramatic shift.

"General, the Northern Army...the Northern Army is here! They're only five kilometers from Scarlet Devil Castle!"

"What?!"

A mouthful of liquor went down his throat, the burning pain turning his face bright red. Colin didn't care about drinking; he hurriedly threw away the bottle, slid down from the roof, and strode towards the city wall.

"What are the rest of the scouts doing! Why haven't they found any trace of the Northern Army? How many of them are there?"

Colin asked anxiously as he walked, and the demon messenger, running to keep up, answered breathlessly.

"The number is approximately six thousand."

"Six thousand..."

Upon hearing this number, Colin's expression became even more tense, and his voice gradually began to tremble.

"Are they cavalry?"

The lance cavalry of the Northern Territory are not to be trifled with, especially those lance cavalry selected through rounds of battles, who are capable of standing up to the ogre legions of the demon race.

"They were all infantry, but it felt strange, inexplicably strange."

The demon messenger couldn't find the right words to describe his feelings, but Colin, who had a keen sense of what was going on, stopped and gestured for him to be quiet.

Boom!Boom!Boom!

The gates of hell were knocked on, and the perfectly synchronized steps brought Colin's unease to its peak. This army, after such a long march, could still maintain such a high level of discipline!

Monsters! This is a level that elite soldiers could never reach. The Northern Territory has brought the monsters that have appeared one after another in the human kingdoms to the territory of the demons!

"What are the defenders on the city wall doing? Why haven't they attacked yet!"

He ordered the messenger to leave the city immediately and seek support from the demon army. Colin heard an eerie silence under the eerie march and hurriedly climbed the city wall.

But the scene before him left Colin frozen in place. There stood a man, or more precisely, the Duke of Oswald of the Northern Territory.

The aura he exuded was like a curtain of solidified night. The demon soldiers, bound by the magic of immortality, were prostrate at his feet, pressed tightly to the ground. Their faces were like dripping sludge, and even their cries were silent.

Oswald leaned against the wall, picked up his pipe, and beckoned to Colin.

Colin walked over instinctively; he already knew about this city and his own fate.

"Why aren't you setting up sentry posts? Have you encountered some difficulties recently?"

Looking up at the sky and down at the ground, Colin felt, whether it was his imagination or not, that the Duke of Oswald was some leader who had come to inspect their defense work.

"Actually, we have cavalry patrols..."

"Where are the patrols?" Oswald asked curiously. If he hadn't made up his mind to take this trip, he would have suspected that he had already been exposed since he hadn't encountered any sentries along the way.

Colin rubbed the dead skin off his hands and gritted his teeth, saying, "We went hunting during this snowy season. Without food, this winter will be tough. But usually, the goblins who live in the forest will also give us warnings."

Oswald nodded. "What's unusual about that?"

"We killed half of the goblins, and the other half fled into the mountains."

"So you didn't send any hidden sentries?"

"They sent one, but only one came back with the news."

After a long silence, Oswald lightly flicked the cigarette between his fingers and joked, "As the lord of a city, still drinking at midnight, what's wrong? Is there a girl you can't let go of?"

"Duke Oswald, what exactly do you want to do?" Colin had no intention of continuing the conversation. From the moment Duke Oswald appeared in the Crimson Demon Castle, whether or not the Crimson Demon Castle was prepared, it could not escape the fate of destruction.

There's no need to be upset, because the person in front of you is a terrifying being capable of easily destroying cities and armies.

"I just want you to do me a favor."

The gates of the Crimson Demon Castle slowly opened, and soldiers of the Loyal Death Legion filed in, quickly heading to various strategic locations.

These long-dead warriors became the local garrison's worst nightmare. Their emanating immortal magic was pervasive, causing a cold, stinging pain when it touched the skin, as if flesh and blood had instantly lost their vitality.

The longer the battle lasted, the less fatigue the opponent showed, and even if they were injured, it was not a big deal.

In contrast, the nerves in the bodies of the demon guards were dying one after another. In the end, amidst painful screams, their chests were ripped open by sword blades, and their already black blood flowed out.

The sounds of fighting along the way awakened the sleeping city, bringing the carnage to a climax. Oswald, who had invited Colin to witness this scene, exhaled a thick cloud of smoke and calmly said, "Take a letter for me to the Demon King, Colin. It's a letter in my own handwriting."

"You're not giving me a chance to live, Duke Oswald!"

Colin turned to look at Jenny, who was walking up the city wall step by step. Jenny ignored their situation and instead activated a magic circle, frantically drawing on the immortal magic power within Oswald's body.

A dark halo flashed, and a large-scale undead invasion descended upon the city. Using loyal soldiers as anchor points, Jenny quickly found the severely wounded and dying demon civilians and soldiers, and then transformed them into undead in large numbers.

Colin lowered his head once more and said bitterly, "If I deliver this letter to His Majesty the Demon King, he will surely chop off my head..."

Oswald glanced at him. "Then where do you think you're going to escape to, the Dwarf Kingdom? Are you sure they'd take in a fallen, disgraced demon general?"

A mournful cry echoes across the wilderness, white bones appear in the night city.

Since the target of her spell was a demon, Jenny Shi, without any scruples, continuously expanded the magic circuit, going all out. The flesh and blood of the demons boiled and detached in the yin wind, directly transforming into the purest undead skeletons.

Oswald, feeling much more relaxed, stretched. Meanwhile, to the north of the city, thousands of demon cavalrymen trampled through the mud beneath the snow and charged toward the Crimson Demon City.

Colin took a deep breath, his eyes showing no relief at the arrival of reinforcements. "Perhaps one day you will regret starting this war against the demons, Duke Oswald."

"You can't just say the enemy started the war when you're being attacked. Let's be realistic, Colin. There are too many things humans and demons have to regret. Destroying only one race is already the best outcome."

Oswald put away his pipe, his long fingers tracing the city's surface. Countless undead armies surged forth, charging towards their former brethren...
