This is a perpetually dark world, because what hangs overhead is not the bright and blazing sun, but a dim and cold blood moon.

In the deepest part of the Demon Realm, within a radius of hundreds of miles, apart from a deep and dilapidated ancient castle, nothing grows and there is no life.

Humanoid skeletons littered the wilderness, and fragments of some divine weapons crafted from precious materials were barely preserved, but no one paid them any attention.

This is the most dangerous forbidden area in the Demon Realm, and also the final battlefield between humans and demons—the Demon King's Castle.

Inside the castle, traces of battle are everywhere, but the throne at the very center of the hall remains unchanged since its creation.

Suddenly, a cold wind swept through the silent castle.

"Buzz" "Buzz" "Buzz"

The row of candlesticks on the wall lit up with eerie blue flames.

The hall was finally bright and airy.

Gray particles rose from the ground and quickly formed eight shapes.

Some resemble humans, some resemble beasts, and some resemble strange geometric shapes.

As the particles solidified, the eight figures stood respectfully beneath the throne like statues, as if welcoming the arrival of a great being.

After an unknown amount of time, a crack appeared in space, and a wisp of black mist quickly emerged from it and hovered silently above the throne.

"Your Majesty, when will the seal be broken? We are eager to set foot in the mortal realm." The humanoid creature on the far left of the eight stepped forward first and bowed to ask for instructions.

"New changes have occurred in the human world; you must continue to wait." The Demon King's majestic voice echoed from the black mist.

"Could it be those so-called guardians again? Your Majesty, there is no need to care about these weak humans. We are the ones who possess true power." The figure seemed unwilling and continued to advise.

"Are you questioning my judgment?" The Demon King's voice carried a hint of displeasure.

"I dare not," the figure said hastily, kneeling on the ground in fear.

"You should all lead your troops back to your respective territories first. I will inform you when the time is right."

"Yes, ma'am."

No one else stepped forward, and after the reply, the eight spirits disappeared from the hall.

The moment the spirit disappeared, the black mist above the throne changed.

The fog continued to dissipate, gradually revealing the shapes hidden within.

It was a terrifying-looking monster.

This monster has three heads and six arms, and walks on four legs. Its body is covered with thick, black scales, and its hands have no fingers, but instead sharp bone blades.

However, at this moment, this monstrous demon king was trembling violently all over.

Scales began to fall off, and his strong limbs could no longer support his body, causing him to collapse onto the throne.

However, the collapse was not over yet; both the strong bones and the robust flesh began to shatter simultaneously.

Every sword strike Wu Yu unleashed finally transcended the river of time and the distance of space, striking the Demon King, who was known as the strongest being in the world.

Soon, only a few small pieces of meat were scattered haphazardly on the throne.

"Is this what humanity is like? Even the ultimate war weapon built for combat has been destroyed by them."

A gasp of surprise echoed from the void.

Then, a strange black sphere appeared out of thin air.

A large, mouth-like opening appeared on the smooth sphere, and the Demon King's body, which had just shattered, gently floated up, then flew into the mouth without falling to the ground.

The crack healed, and it became a perfect sphere again.

A drop of blood suddenly appeared above the sphere, then dripped onto the sphere and merged into it.

"Let's try again, this time choosing a human as the prototype. Hopefully, it will bring me some surprises."

The mysterious voice appeared once again, ethereal and illusory, yet it seemed to carry a hint of weariness.

The sphere began to change, and soon became a huge egg, with an embryo that could be vaguely seen growing inside.
